2019年中考英语复习阅读理解训练题 (9)
2019年中考英语：阅读理解训练题（8）附答案第一篇（2019中考科普环保类选练）Satellites are an important part of our ordinary lives. For example, the information for weather forecasts is sent by satellite. Some satellites have cameras which take photographs of the Earth to show how clouds are moving. Satellites are also used to connect our international phone calls.Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites. Airplane pilots also sometimes use a satellite to help them find their exact location.We use satellites to send television pictures from one part of the world to another. They are usually 35，880 kilometers above the equator. Sometimes we can see a satellite in the sky and it seems to stay in the same place. This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates.A satellite must orbit the Earth with its antennae facing the earth. Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position. This usually happens about every five or six days.Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth. A satellite usually works for about 10-12 years. Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired. Often，very old or broken satellites are left in space to orbit the Earth for a very long time. This is very serious because some satellites use nuclear power and they can crash into each other.1.Which of the following is NOT done by satellites according to the passage?A. Sending information for weather forecast.B. Taking photographs of the Earth.C. Sending TV pictures.D. Providing food for airplane pilots.2.What’s the speed the earth rotates at?A.35,880 kilometers per hour.B.335,880 kilometers per hour.C.11,000 kilometers per hour.D.110,000 kilometers per hour3.Why does the satellite move around the world at the same speed as the Earth rotates?A. In order to take photographs.B. In order to stay in a certain position in the orbit.C. In order to move away from its orbit.D. In order to send television pictures.4.What does the underlined word “This” in the 3rd paragraph refer to?A. Asatellite.B.A little rocket.C. A satellite seems to stay in the same place in the sky.D. The satellite puts the rockets in the right position.5.Which is true of satellites?A.A satellite usually works for about 10-12 years.B. Every time a satellite gets broken, it is brought back to the Earth to be repaired.C.A broken satellite is never left in space.D. They often crash into each other.参考答案DCBCA第二篇阅读理解****EatingAn important question about eating out is who pays for the meal. If a friend of yours asks you to have lunch with him, you may say something like this,“I’m afraid it’ll have to be someplace cheap, as I have very little money." The other person may say,“O K, I’ll meet you at McDonald’s."This means that the two agree to go Dutch, that is, each person pays for himself. He may also say,“Oh, no. I want to take you to lunch at Smith’s," or“I want you to try the Chinese dumplings there. They’re great." This means the person wants to pay for both of you. If you feel friendly towards this person, you can go with him and you needn’t pay for the meal. You may just say,“Thank you. That would be very nice."American customs（1） about who pays for dates（2） are much the same as in other parts of the world. In the old days, American women wanted men to pay for all the meals. But, today, a university（3） girl or a woman in business world will usually pay her way during the day. If a man asks her for a dance outside the working hours, it means “Come, as my guest（4）.” So as you can see, it is a polite thing to make the question clear at the very beginning.Notes:（1）custom/`kstm/n. 风俗（2）date/deIt/n.约会（3）university/、ju：nI`v：sItI/n. 大学（4）guest/gest/n. 客人1.The passage tells us .A.how to eat outB.where to eat outC.what to eat outD.who pays for the meal2.If you have little money, .A.you’ll have a cheap mealB.you’ll borrow some from othersC.you’ll ask your friend to pay for your mealD.you won’t want your friends to ask you to dinner3.“Go Dutch" in this passage means .A.去饭馆B.就餐C.订餐D.各自付款4.Sometimes your friend takes you to lunch.

If I pass the test with good grades, I can get to the 10th grade and choose a good school to study in. Now I am trying my best to achieve this. At the same time, I’m monitor in my class, which meansI should do lots of things for my class. ①I am so busy with my schoolwork and duties as monitor that I don’t have enough time to keep a balance between them. Gradually I become lazy. ②The other day, my headteacher told me that she was disappointed in my poor performance as class monitor. Her words really discouraged(使泄气) me. What should I do now, to give up or not to give up as class monitor? I must do my best in school because how well I do will influence where I go after this school year is over and it can affect the rest of my life. Being class monitor is also a valuable(宝贵的) learning experience because my teacher trusts me to be a goo d leader. ③I don’t want to go to my parents for suggestions, for they will get worried about me. Can you tell me how to choose?Yours,Gates1. 根据①处内容，完成下面的句子。
CarbonFootprint-CenterforSustainableSystems
Carbon Footprint“A carbon footprint is the total greenhouse gas (GHG) emissions caused directly and indirectly by an individual, organization, event or product.”1 It is calculated by summing the emissions resulting from every stage of a product or service’s lifetime (material production,manufacturing, use phase, and end-of-life disposal). Throughout a product’s lifetime, or lifecycle, different greenhouse gases (GHGs) may be emitted, such as methane and nitrous oxide, each with a greater or lesser ability to trap heat in the atmosphere. These differences are accounted for by calculating the global warming potential (GWP) of each gas in units of carbon dioxide equivalents (CO 2e), giving carbon footprints a single unit for easy comparison. See the Center for Sustainable Systems’ “Greenhouse Gases Factsheet” for more information on GWP.Sources of EmissionsFood• On average, U.S. household food consumption emits 8.1 metric tons of CO 2e each year. The production of food accounts for 83% of emissions, while its transportation accounts for 11%.3• The emissions associated with food production consist mainly of carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (NO 2), which result primarily from agricultural practices.3• Meat products have larger carbon footprints per calorie than grain or vegetable products because of the inefficient transformation of plant energy to animal energy.3• Ruminant animals such as cattle, sheep, and goats produced 164 million metric tons (mmt) in CO 2e of methane in the U.S. in 2014 through enteric fermentation (digestion).4• Eating all locally grown food for one year could save the GHG equivalent of driving 1,000 miles, while eating a vegetarian meal one day a week could save the equivalent of driving 1,160 miles.3• A vegetarian diet greatly reduces an individual’s carbon footprint, but switching between different types of meat can have a major impact as well. For example, replacing all beef consumption with chicken for one year leads to an annual carbon footprint reduction of 882 pounds CO 2e.5• Organic food typically requires 30-50% less energy during production but requires one-third more hours of human labor compared to typical farming practices, making it more expensive.6Household Emissions• For each kilowatt hour generated in the U.S., an average of 1.2 pounds of CO 2 is released at the power plant.7 Coal releases 2.2 pounds, petroleum releases 1.9pounds, and natural gas releases 0.9 pounds. Nuclear, solar, wind, and hydroelectric release no CO 2 when they produce electricity, but emissions are released during upstream production activities (e.g., solar cells, nuclear fuels, cement production).4,8 • Residential electricity use in 2014 emitted 750.2 mmt CO 2e, 11% of U.S. total.4 • Heating and cooling account for about 53% of the energy use in a typical U.S. Pounds of CO 2e per Serving 2,7,13(4 oz. meat, 1/2 c. asparagus & carrots, 8 oz. liquids)Greenhouse Gases from Average FoodConsumption 2Cite as: Center for Sustainable Systems, University of Michigan. 2016. “Carbon Footprint Factsheet.” Pub. No. CSS09-05.August 2016• Gasoline releases 19.6 pounds of CO 2 per gallon when burned, compared to 22.4 pounds per gallon for diesel.16 However, diesel has 11% more BTU per gallon, which improves its fuel economy.17• The average passenger car emits 0.81 pounds of CO 2 per mile driven.13• Automobile fuel economy can improve 7-14% by simply observing the speed limit. Every 5 mph increase in vehicle speed over 50 mph is equivalent to paying an extra $0.15-$0.30 per gallon.18• Commercial aircraft GHG emissions vary according to aircraft type, the length of trip, occupancy rates, and passenger and cargo weight, but totaled 116.3 mmt CO 2e in 2014.4 In 2014, the average domestic commercial flight emitted 0.42 pounds of CO 2e per passenger mile. Emissions per domestic passenger-mile decreased 41% from 1990-2014, due to increased occupancy and fuel efficiency.4,19• On average, trains release 0.32 pounds of CO 2e per passenger mile, but this varies with occupancy and the length of the trip.20Solutions and Sustainable ActionsWays to Reduce Carbon Footprint• Eat local, vegetarian, or organic foods. Fornon-vegetarians, replace some beef consumption with chicken.2,3,6• Walk, bike, carpool, use mass transit, or drive a best-in-class vehicle.21• Smaller homes use less energy. Averagehousehold energy use is highest in houses (103.6 million BTU), followed by apartments with 2-4 units (76.1 million BTU), mobile homes (67.9 million BTU), and apartments with 5+ units in the building (46.3 million BTU).11• Replacing 80% of conditioned roof area on commercial buildings in the U.S. with solar reflective material would offset 125 mmt CO 2 over the structures’ lifetime, equivalent toturning off 36 coal power plants for one year.22,23• Using a low-flow shower head can save 350 pounds of CO 2e per year. Setting the temperature to 120°F can help improve a hot water heater’s efficiency.24• Turn off your TV, computer, and other electronics when not in use to reduce your carbon footprint by thousands of pounds of CO 2e each year. Unplug unused electronics to further reduce your footprint.24• Choose energy-efficient lighting. If every home in the U.S. replaced their 5 most used light bulbs with Energy Star bulbs, the reduction in carbon emissions would be equivalent to removing 10 million cars from the road.25• Recycling half a household’s waste can save 2,400 pounds of CO 2 per year. Buying products with minimal packaging also helps reduce waste. For every 10% of waste reduction, 1,200 pounds of CO 2e are avoided.24• Shop smart and purchase items with a comparatively low carbon footprint when possible. Some manufacturers have begun assessing and publishing their products’ carbon footprints.Carbon Footprint CalculatorUse one of these tools to estimate your personal or household greenhouse gas emissions and explore the impact of different techniques to lower those emissions:• Global Footprint Network: /en/index.php/gfn/page/calculators/• The Nature Conservancy: /greenliving/carboncalculator/• U.S. Environmental Protection Agency: /carbon-footprint-calculator/1.

He is Zhang Jiacheng, from Guangdong Province. In the video, facing a taller, stronger, and older opponent （对手），he isn't afraid at all.Attracted by his good skills in the video, many people even fail to know that Zhang Jiacheng has only one arm. Although the young boy lost one of his arms in an accident, he became crazy about playing basketball at 12. "Work hard or just give up," he always says. Thus, he spent all of his free time on it without considering his body condition.People's attention has encouraged him to work harder towards his goal---to become a top basketball player "I just keep practising every day to improve myself whether at home or in the playground, he says, "My biggest challenge is to control the ball much better." After only a year of hard practising, Zhang Jiacheng has improved his skills greatly. Through patience, confidence and determination, the young basketball player is getting closer to his life goal.His effort and courage finally caught the attention of Yi Jianlian, a Chinese professional （MR 业的）basketball player, who shared the video on his own Weibo.11．Why do people fail to know the boy has only one arm?A．Because his good skills attract people.B．Because his life goal encourages people.C．Because he jumps to an amazing height.D．Because he hides the other arm carefully.12．What is the biggest challenge for the boy?A．Controlling the ball better.B．Keeping his balance.C．Making some more friends.D．Getting closer to his family.13．What is the boy's goal according to the text?A．To live a comfortable life.B．To become a top basketball player.C．To set up a basketball team.D．To build a large gym for his school.14．Which of the following can best describe the young boy?A．Humorous.B．Confident.C．Careless.D．Noisy.15．What will probably be talked about in the following paragraph?A．Yi Jianlian's cute pets.B．Yi Jianlian's courage.C．The video's influence.D．The video's quality.DThe South American country of Bolivia has a highly varied climate which ranges from hot and moist in the east to high and cool in the west.In fact,the one missing element is a sea breeze,since Bolivia has no coastline.The population of Bolivia is about three and a half million.Three-fourths of the people live in the mountainous regions,where the altitude varies from 8,000 to over 13,000 feet.The highest mountains are over 21,000 feet high.About one-tenth of the total population is white.Some of these white citizens are descendants of the Spanish conquerors who came to South America with Pizarro in the sixteenth century.Others white citizens migrated to Bolivia from Europe and the United States because of their interest in trade.The white people in Bolivia control the government and the industries.About one-fourth of the Bolivians are mixed Indian and white.They usually work as shopkeepers or government employees.More than half of the Bolivians are full-blooded Indians.They are the descendants of the people who made up the Inca Empire.The Inca rulers claimed that they come from a mythical race living on an island in Lake Titicaca.This lake is the largest in South America and one of the highest lakes in the world.When the Spanish soldiers conquered the Incas,they imposed their own government on the country.They also tried to force the people to practice Roman Catholicism and to speak Spanish.However,even today,most of the Indians still speak their own languages.16．Which of the following statements is true according to Paragraph 1?A．West of Bolivia is the Pacific Ocean.B．East of Bolivia is the Atlantic Ocean.C．North of Bolivia is the Arctic Ocean.D．There is no ocean around Bolivia.17．Bolivians live in the mountainous regions.A．2,625,000B．3,500,000C．1,750,000D．875,00018．The Indians were forced to speak .A．English B．FrenchC．Spanish D．their own language19．The underlined word “descendants” in Paragraph 3 means .A．forefathers B．offspringC．ancestors D．grandfathers20．Paragraph 4 mainly tells us .A．about 875,000 Bolivians are mixed Indian andwhiteB．some Bolivians serve as shopkeepers or government employeesC．Lake Titicaca is one of the highest lakes in the worldD．the blood relation of Bolivians第二部分语言知识运用（共两节，满分 25分）第一节完形填空（共15小题；每小题1分，满分15分）阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填人空白处的最佳选项。

四级真题——阅读训练（4.1）队别： [填空题] *请输入数字Section BDirections: In this section, you are going to read a passage -with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The quiet heroism of mail delivery[A]On Wednesday, a polar wind brought bitter cold to the Midwest. Overnight, Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colder than Antarctica （南极洲），Alaska, and the North Pole. Wind chills were 64 degrees below zero in Park Rapids, Minnesota and 45 degrees below zero in Buffalo, North Dakota, according to the National Weather Service. Schools, restaurants, and businesses closed, and more than 1,000 flights were canceled.[B]Even the United States Postal Service （USPS） suspended mail delivery. "Due to this arctic outbreak and concerns for the safety of USPS employees/9 USPS announced Wednesday morning, "the Postal Service is suspending delivery Jan. 30 in some 3-digit ZIP Code locations." Twelve regions were listed as unsafe on Wednesday, on Thursday, eight remained.[C]As global surface temperatures increase, so does the likelihood of extreme weather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and other natural disasters cost at least $49 billion in the United States. As my colleague Vann Newkirk reported, Puerto Rico is still confronting economic and structural destruction andresource scarcity from 2017's Hurricane Maria. Natural disasters can wreck a community 5s infrastructure, disrupting systems for months or years. Some services, however, remind us that life will eventually return, in some form, to normal.[D]Days after the deadly 2017 wildfires in Santa Rosa, California, a droned无人机）caught footage （连续镜头）of a USPS worker, Trevor Smith, driving through burned homes in that familiar white van, collecting mail in an affected area. The video is striking: The operation is familiar, but the scene looks like the end of the world. According to Rae Aim Haight, the program manager for the national-preparedness office at USPS, Smith was fulfilling a request made by some of the home owners to pick up any mail that was left untouched. For Smith, this was just another day on the job. "I followed my route like I normally do,” Smith told a reporter. As I came across a box that was up but with no house, I checked, and there was mail—outgoing mail—in it. And so we picked those up and carried on.“"[E]USPS has sophisticated emergency plans for natural disasters. Across the country,285 emergency management teams are devoted to crisis control. These teams are trained annually using a framework known as the three Ps: people, property, product. After mail service stops due to weather, the agency's top priority is ensuring that employees are safe. Then it evaluates the health of infrastructure, such as the roads that mail carriers drive on. Finally, it decides when and how to re-open operations. If the destruction is extreme, mail addressed to the area will get sent elsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming New Orleans mail to existing mail facilities in Houston. Mail that was already processed in New Orleans facilities was moved to an upper floor so it would be protected from water damage.[F]As soon as it's safe enough to be outside, couriers｛由K递员）start distributing accumulated mail on the still-accessible routes. USPS urges those without standing addresses to file change-of-address forms with their new location. After Hurricane Katrina hit in 2005, mail facilities were set up in dozens of locations across the country in the two weeks that USPS was unable to provide street delivery.[G]Every day, USPS processes, on average, 493.4 million pieces of mail一anything from postcards to Social Security checks to medicine. Spokespeople from both USPS and UPS told me all mail is important. But some mail can be extremely sensitive and timely. According to data released in January 2017, 56 percent of bills are paid online, which means that just under half of payments still rely on delivery services to be completed.[H]It can be hard to identify which parcels are carrying crucial items such as Social Security checks, but USPS and UPS try their best to prioritize sensitive material. They will coordinate with the Social Security Administration to make sure that Social Security checks reach the right people in a timely fashion. After Hurricane Florence and Hurricane Michael last fall, USPS worked with state and local election boards to make sure that absentee ballots were available and received or time.[I]Mail companies are logistics (3iE) companies, which puts them in a special position to help when disaster strikes. In a 2011 USPS case study, the agency emphasized its massive infrastructure as a "unique federal asset" to be called upon in a disaster or terrorist attack. "I think we're unique as a federal agency," USPS official Mike Swigart told me, "because we're in literally every community in this country... We're obligated to deliver to that point on a daily basis."[J]Private courier companies, which have more dollars to spend, use their expertise in logistics to help revitalize damaged areas after a disaster. For more than a decade, FedEx has supported the American Red Cross in its effort to get emergency supplies to areas affected by disasters, both domestically and internationally. In 2012, the company distributed more than 1,200 MedPacks to Medical Reserve Corps groups in California. They also donated space for 3.1 million pounds of charitable shipping globally. Last October, the company pledged $1 million in cash and transportation support for Hurricanes Florence and Michael. UPS's charitable arm, the UPS Foundation, uses the company5 s logistics to help disaster-struck areas rebuild. "We realize that as a company with people, trucks, warehouses, we needed to play a larger role： said Eduardo Martinez,the president of the UPS Foundation, The company employs its trucks and planes to deliver food, medicine, and water. The day before I spoke to Martinez in November, he had beer touring the damage from Hurricane Michael in Florida with the American Red Cross. “We have an obligation to make sure our communities are thriving,9, he said.[K]Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a normal life can be difficult, but some small routines—mail delivery being one of them—may help residents remember that their communities arestill their communities. "When they see that carrier back out on the street,5, Swigart said, “that's the first sign to them that life is starting to return to normal.”36.The United States Postal Service has a system to ensure its employees' safety.

[单选题] * ABCDEGH(正确答案)IJKPassage OneQuestions 46 to 50 are based on the following passage.Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge-Based Artificial Intelligence. This online course is a core requirement of Georgia Tech's online Master of Science in Computer Science program. Professor Goel already had eight teaching assistants, but that wasn't enough to deal with the overwhelming number of daily questions from students.Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn't too great. But Goel and his team sourced the online discussion forum to find all 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments, and sufficient time, Jill was able to answer the students9 questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn't know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldn't tell it apart from a real human being. Goel didn't inform them about Jill's true identity until April 26. The students were actually very positive about the experience.The goal of Professor GoeFs virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. The name Jill Watson will, of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of artificial intelligence than, say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46.What do we learn about Knowledge-Based Artificial Intelligence ? [单选题] *A)It is a robot that can answer students' questions.B)It is a course designed for students to learn online.(正确答案)C)It is a high-tech device that revolutionizes teaching.D)It is a computer program that aids student learning.47 .What problem did Professor Goel meet with ? [单选题] *A)His students were unsatisfied with the assistants.B)His course was too difficult for the students.C)Students9 questions were too many to handle.(正确答案)D)Too many students dropped out of his course.48.What do we learn about Jill Watson ? [单选题] *A) She turned out to be a great success.(正确答案)B) She got along pretty well with students.C) She was unwelcome to students at first.D) She was released online as an experiment.49.How did the students feel about Jill Watson? [单选题] *A) They thought she was a bit too artificial.B) They found her not as capable as expected.C) They could not but admire her knowledge.D) They could not tell her from a real person.(正确答案)50. What does Professor Goel plan to do next with Jill Watson? [单选题] *A)Launch different versions of her online.B)Feed her with new questions and answers.C)Assign her to answer more of students9 questions.(正确答案)D)Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being engaging, and having a sense of humor don't hurt. Those are a few of the traits of successful science crowdfunding efforts that emerge from a recent study that examined nearly 400 campaigns. But having a large network and some promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken off in recent years for everything from making movies to producing water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goals, but others have fallen short of reaching even modest targets.To determine what separates science crowdfunding triumphs from failures, a team led by science communications scholar Mike Schafer of the University of Zurich examined the content of the webpages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report in Public Understanding of Science. For one, they use a crowdfunding platform that specializes in raising money for science, and not just any kind of project. Although sites like Kickstarter take all comers, platforms such as Experiment, com and Petridish. org only present scientific projects. For another, they present the project with a funny video because good visuals and a sense of humor improved success. Most of them engage with potential donors, since projects that answered questions from interested donors fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% receiving less than $1000. The more money a project sought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project's success, most notably, the size of a scientist's personal and professional networks, and how much a researcherpromotes a project on their own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researchers5 efforts to reach the public, and people give because "they feel a connection to the person" who is doing the fundraising—not necessarily to the science.51.What do we learn about the scientists trying to raise money online for their projects? [单选题] *A)They did not raise much due to modest targets.B)B) They made use of mixed fundraising strategies.C)Not all of them achieved their anticipated goals.(正确答案)D)D) Most of them put movies online for the purpose.52.What is the purpose of Mike Schafer's research of recent crowdfunding campaigns? [单选题] *A)To create attractive content for science websites.B)B) To identify reasons for their different outcomes.(正确答案)C)To help scientists to launch innovative projects.D)D) To separate science projects from general ones.53.What trait contributes to the success of a crowdfunding campaign? [单选题] *A)The potential benefit to future generations.B)B) Its interaction with prospective donors.(正确答案)C)Its originality in addressing financial issues.D)D) The value of the proposed project.54.What did the researchers think of the financial targets of crowdfunding projects? [单选题] *A)They should be small to be successful.(正确答案)B)B) They should be based on actual needs.C)They should be assessed with great care.D)D) They should be ambitious to gain notice.55.What motivates people to donate in a crowdfunding campaign ? [单选题] *A)The ease of access to the content of the webpage.B)Their desire to contribute to the cause of science.C)The significance and influence of the project itselfD)Their feeling of connection to the scientists themselves.(正确答案)。

高考英语一轮复习 Unit 4 Global warming课时作业高三英语试题 (2)
入舵市安恙阳光实验学校Unit 4 Global warmingⅠ.阅读理解A[2020·兰州实战模拟]The effect of climate change extends beyond ruining Earth's environment and our physical safety. A report published this week suggests that climate change has a negative effect on our mental health, too.The study, published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS), links an increase in monthly temperatures to a rise in mental health issues. The experimental evidence stems from meteorological (气象学的) data paired with information collected from nearly 2 million randomly sampled residents in the United States. The data was collected over the span (跨度) of a decade.“We find that experiences with hotter temperatures and added rainfall each worsen mental health, that longlasting warming associates with an increased popularity of mental health issues, and that exposure to tropical cyclones (热带气旋), likely to increase in frequency in the future, is linked to worsened mental health，” authors of the stu dy stated. “These results provide added largescale evidence to the growing link between climate change and mental health.”The report specifically focused on mental health outcomes due to the effects of environmental stress — such as temperature, rainfall, and tropical cyclones —but other climate changerelated issues are likely to affect mental health as well — specifically, the stress and anxiety of knowing natural disasters could be more frequent as temperatures rise.1．From the newlypublished report,we learn that the climate change may ________.A．save a lot of people's livesB．cause unbelievable disastersC．influence people's mental healthD．greatly change people's life styles2．Why did the author mention “the span of a decade” in Paragraph 2?A．To stress the importance of the study.B．To show that the study cost too much money.C．To explain the difficulties and hardships of the study.D．To indicate that the study is objective and believable.3．Where can we find some specific results of the study?A．In Paragraph 1. B．In Paragraph 2.C．In Paragraph 3. D．In Paragraph 4.4．What can we infer from the last paragraph?A．The study has its limits.B．The results of the study aren't satisfactory.C．The environmental problems can't be solved.D．Mental health is determined by climate change.B[2020·石家庄模拟]CocaCola, which reportedly produced more than 3 million tons of plastic packaging in 2017, announced that it wants to “help fix the world's plastic waste problem one community (社区) at a time”．The soda giant is doing so by providing $5.4 million for recycling programs in cities like Atlanta, Boston, Denver and Houston. In these cities, partners, like The Green Blue Institute and The Recycling Partnership, which receive the money, will work together to improve recycling rates.“We focus on areas where we have the ability to make the biggest influence on communities through the funding and expert skills of CocaCola employees，” Carlos Pagoaga, CocaCola's group director of community partnerships, said in a statement. “In each city, local partners will work together to identify barriers to recycling on a local level and test a range of solutions，” he added. “We hope the learning from these ‘model markets’ can offer solutions to other cities facing similar ch allenges.”As part of the effort, The Recycling Partnership and the city of Atlanta, where the CocaCola company's headquarters are based, will send street teams out to open recycling carts and leave citizens cards informing them what they can and can't recycle, and let them know how their efforts work.“Two of the most urgent problems with recycling in the U．S. today are lack of access and the pollution in recycling，” Keefe Harrison, CEO of The Recycling Partnership, said in a statement. “We know from the success of Atlanta in 2017 that the citizens want to recycle, and that communicating with them in the street works.”Last year, CocaCola announced its task to collect and reuse a bottle or can for each one it sells, and increase the amount of its products out of recycled materials to 50% by 2030. It also aims to make all its packaging fully recyclable by 2025.5．What does CocaCola company intend to do in the program?A．Produce less packaging.B．Help deal with plastic waste.C．Pick up waste in communities.D．Build a plant to recycle plastic waste.6．What's Paragraph 2 mainly about?A．How CocaCola conducts its program.B．What organizations participate in the program.C．How CocaCola chooses cities for the program.D．What the local people do in CocaCola's p rogram.7．What do street teams do to help?A．Sort out all kinds of waste in the city.B．Look into the cause of pollution.C．Instruct local people what to recycle.D．Hand cards to the locals in person.8．What does Keefe Harrison think of the program?A．Promising. B．Difficult.C．Pioneering. D．Costly.Ⅱ.完形填空[2019·成都第三次诊断]I recently visited India to meet women with AIDS. Having AIDS is considered as a mark of disgrace and the punishment is abandonment.

Eastern and Western coasts of the United States. Native to the northeast Atlantic seaboard from Norway to Mauritania, this crab has made its way around the world over the last 200 years, traveling along with cargo ships and traders into new ports and establishing populations in several different countries.The green crab is a problematic invasive species because it alters the function and organization of the different marine habitats it enters, including intertidal rocky shores, intertidal mudflats, marshes, andeelgrass beds. This crab is also capable of reducing biodiversity and altering food webs. There is evidence that green crabs have reduced populations of native clams in New England, and also harmed other commercially important bivalves including the scallops and quahogs.How to Identify a Green CrabAdult green crabs have mottled shells, usually dark brown or green in color, that reach around 3 to 4 inches in width. They are sometimes misidentified as native species including juvenile Dungeness and helmet crabs, but can be distinguished primarily by a set of five triangular teeth, or spines, evenly spaced between the eyes and the widest part of the shell on either side.As our climate changes, this species will continue expanding into new environments, being tolerant of a wide range of hot and cold temperatures, according to research published in the Journal of Experimental Biology.How the Green Crab Became an Invasive SpeciesGreen crabs (Carcinus maenas) are also called European green crabs in Canada and the United States, while in the British Isles they're typically referred to as shore crabs or green shore crabs. They were first documented on the East Coast in the early 19th century, one ofintroduced in the late 20th century). It is likely that one of these lineagesrom warmer native waters, while the other was native to cooler, northern environments.Both of these lineages of green crab eventually made their way to eastern Canada and hybridized, creating a point of contact in Nova Scotia. In that location, scientists found that the mean high temperature at which cardiac function fails in adult crabs is consistently higher in southern populations, which are adapted to overall warmer sea surface temperatures. This indicates that green crabs are highly adaptable and change genetically to accommodate different native and non-native aquatic environments.Initial introductions of the green crab to the East Coast came from ships arriving in New England from European waters, likely releasing ballast water (water stored in a ship's hold to provide needed weight) carried from overseas that contained the crabs ortheir larvae. It is also likely that green crabs arrived to new areas in packing materials as well as shipments of live seafood.The crab's West Coast introduction may have occurred via boxes of live fishing bait in San Francisco. Once these crabs enter the water, their tiny larvae disperse widely and are almost impossible to detect and remove.Problems Caused by the Green CrabThe green crab has had a wide-reaching impact on the United States' coastal waters since its introduction. Significant losses to commercial fisheries and natural ecosystems have been documented in waters where the crab now resides, including decreased populations of clams, scallops, quahogs, and other native crab species.These crabs have a wide variety of food preferences, and their ability to out-compete native species for food resources, high reproductive capacity, and wide environmental tolerances lend them the capacity to fundamentally alter community structure in coastal ecosystems. In Canada, for example, the aggressive green crab has been dubbed the "cockroach of the sea," and is known for completely mowing down eelgrass beds, a valuable ecosystem and food source for manyspecies. There is also evidence of a cascading impact on broader fish communities where green crabs are present.Complicating any understanding of the full scope of the impactaquatic environments and also threatening native crabs and other species in the region. More research is required to fully understandenvironments.Green crabs established along the East Coast long before invasion biology was a science, and the ability of their small eggs to be dispersed through tidal currents means that even new populations are difficult to control. That said, there have been efforts to trap crabs in Washington state as well as eastern Canada, and catch rates of green crabs declined in areas where government officialsnewly present.Like with many other invasive species, some advocates are working to create a market for the crab by advertising its culinaryprepare the crab, as well as dozens of delicious recipes, as part of a mission to educate Americans on the green crab's appeal.。
华氏温度的英文缩写
华氏温度的英文缩写The English abbreviation for Fahrenheit temperature is "°F". Fahrenheit temperature is a temperature scale named after the German physicist Daniel Gabriel Fahrenheit, who developed it in 1724. It is commonly used in the United States, some parts of Canada, and a few other countries.The Fahrenheit scale differs from the Celsius scale, which is the international standard temperature scale. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F at sea level. In contrast, on the Celsius sca le, water freezes at 0°C and boils at 100°C.The Fahrenheit scale is based on a series of fixed points, including the temperature of a mixture of ice, salt, and water (0°F), human body temperature (98.6°F), and the temperature of a water-steam mixture (212°F). These fixed points are used to divide the scale into equal intervals.Although the Celsius scale is the internationalstandard, the Fahrenheit scale is still widely used in the United States and some other countries. This is partially due to tradition and inertia, as well as the fact that Fahrenheit temperatures are often used in weather reports, cooking recipes, and other everyday applications.In scientific and engineering applications, however, the Celsius scale is generally preferred because it is based on absolute zero, the lowest possible temperature at which all molecular motion stops. The Celsius scale also aligns with the Kelvin scale, which is used in thermodynamics and other physical sciences.Overall, while the Fahrenheit scale is still used in some contexts, it is less common than the Celsius scale in most scientific and engineering applications. As technology and globalization continue to advance, it is likely that the Celsius scale will become more widely used and accepted worldwide.。
各个国家的四季和全球气温变化 英语作文
各个国家的四季和全球气温变化英语作文全文共5篇示例，供读者参考篇1The Seasons Around the World and Global WarmingHi there! My name is Jamie and I'm going to tell you all about the seasons in different countries and how the planet is getting warmer. It's a really important topic that grown-ups talk a lot about these days.First, let me explain what seasons are. Seasons are the different parts of the year when the weather changes. In many places, there are four seasons: winter, spring, summer, and fall (or autumn). But in some parts of the world, there are just two seasons or even no seasons at all!In the United States and many other countries far away from the equator, we have four seasons that go in a cycle every year. Winter is the coldest season with snow, ice, and freezing temperatures. Then spring comes and things start blooming and warming up. Next is summer which is hot and sunny. Finally, fall brings cooler weather and leaves changing colors before winter comes around again.But in places closer to the equator (that's an imaginary line around the middle of the Earth), the seasons are very different. Let me tell you about a few examples:In Kenya in East Africa, they really only have two seasons - a dry season and a wet season. The dry season is hot and the wet season brings heavy rains. There's no winter like we have with bare trees and snow.In Brazil, which is in South America, the seasons are opposite from the ones we have in North America because it's in the opposite hemisphere (half of the Earth). So when we have summer in the United States, Brazil has winter. Crazy, right?Then there are places like Colombia that don't really have any seasons at all because they are so close to the equator. The weather pretty much stays the same all year round - not too hot and not too cold.I think having four seasons is the most fun because you get to experience different types of weather. I love sledding in the winter, watching flowers bloom in spring, swimming in summer, and jumping in leaf piles in fall. But all the seasonal patterns around our planet are really neat!Okay, now let me tell you about something called global warming that is changing the seasons and climate of the whole Earth. Global warming means the overall temperature of the planet is increasing year after year. This is happening because humans are burning lots of coal, oil, and other fossil fuels which release gases that trap extra heat in the atmosphere.As the Earth keeps getting warmer, the seasons are shifting and changing in weird ways. Winters aren't as cold as they used to be in many places. Spring comes earlier than normal. Summers are becoming extremely hot with heat waves and droughts. And fall is arriving later than usual.Melting glaciers and rising sea levels are other major effects of global warming. You may have seen pictures of little baby polar bears stranded because the ice they live on is melting due to warmer temperatures. So sad!Many of the plants and animals on Earth are getting confused by these shifting seasons too. Flowers are blooming sooner, birds are migrating at different times, and some species can't adapt fast enough to the changing climate.The good news is that grown-ups all around the world are working really hard to try and slow down global warming before it creates even bigger problems. We are finding ways to usecleaner energy that doesn't release as many heat-trapping gases. We're planting more trees which remove carbon dioxide from the air. And we're trying to conserve energy and resources.But we could still use your help too! Here are some things kids can do:Reduce, reuse, recycle as much as possibleTurn off lights and electronics when not in useWalk, bike or take public transportation instead of riding in a carStart a recycling program at your schoolPlant trees and gardensSpread awareness about global warmingThose are just a few ideas. If we all work together, we can help make sure the Earth's seasons don't get too wacky and out of control in the future. We want the beautiful seasons and natural environments to be preserved for generations to come.Thanks for reading my essay! I tried to explain seasons around the world and global warming in a simple way. But it's obviously a very complex issue that even grown-ups are still trying to fully understand. I'll do my part, and I hope you will too.The Earth is our one and only home in this amazing universe after all!篇2The Seasons Around the World and Climate ChangeHave you ever wondered why the seasons are different in various parts of the world? And have you heard about climate change and how it's affecting the weather patterns everywhere? Well, let me tell you all about it!In many countries, there are four distinct seasons - winter, spring, summer, and fall (or autumn). But in some places, the seasons are quite different or even non-existent! Isn't that crazy? Let me break it down for you.Winter WonderlandsDuring the winter months, lots of countries in the Northern Hemisphere experience freezing temperatures, snow, and ice. Places like Canada, Russia, Sweden, and even parts of the United States can get really, really cold! Kids living there have to bundle up in warm coats, hats, scarves, and mittens to stay toasty. Many schools close for "snow days" when the weather is too intense. How fun! Imagine building the most epic snowmen and having epic snowball fights.But you know what's really cool? The Northern Lights! Also called the Aurora Borealis, these are beautiful, dancing lights in shades of green, pink, and purple that appear in the night sky. They're best seen in the Arctic regions during the winter. I'd love to witness that someday!Spring ShowersAh, springtime! When the snow starts melting and new life begins to bloom after the harsh winter. Many countries in the middle latitudes, like the U.S., U.K., France, and Japan, experience a spring season full of rain showers, blooming flowers, and temperatures that are just right - not too hot, not too cold.My favorite part of spring is definitely seeing all the cute baby animals that are born, like lambs, chicks, and bunnies. Easter celebrations with egg hunts and chocolates are fun too! The spring showers do make it a bit muddy though. Don't forget your rain boots!Summertime SizzleSummer is often the hottest season across many parts of the world. Countries closer to the equator, like those in South America, Africa, and Southeast Asia, can get extremely hot andhumid. Temper atures can soar way past 100°F (37°C)! Phew, I'm sweating just thinking about it.That's why kids in these regions go swimming, eat lots of ice cream, and try to stay in the shade as much as possible. Beaches, lakes, and water parks are super popular during these toasty months. Who doesn't love splashing around in cool water when it's scorching hot outside? Sign me up!Fallin' for AutumnLast but not least, autumn (or fall) is when temperatures start to cool down again after summer. The leaves on trees change into gorgeous shades of red, orange, and yellow before falling off. Autumn is big in countries with large forests, like in the Eastern U.S., Canada, and Europe.Two of the most exciting parts of fall are Halloween at the end of October and Thanksgiving in November (at least where I'm from). Dressing up in costumes and trick-or-treating for candy is so much fun! Then we get to stuff our faces with delicious turkey, mashed potatoes, and pumpkin pie. YUM!Weird Weather PatternsNow, as amazing as the four seasons are, things start to get a bit wacky in certain parts of the world. Some places really onlyexperience two seasons - wet and dry. The regions close to the equator, like in parts of Africa, South America, and Southeast Asia, have this pattern.During the wet season, it can rain pretty much every day for months. Everything is muggy and damp. Then in the dry season, you may not see a single raindrop for just as long! The temperatures stay very hot and humid though. That's why desert regions near the equator don't really have seasons at all. It's just hot and dry all year round. No surprise there!The Curious Case of Climate ChangeOkay, now for the serious part. Whether you live where there are four seasons or just two, all these normal weather patterns are being affected by something called climate change. Essentially, the Earth is getting warmer due to human activities like burning fossil fuels and deforestation.As the planet heats up, the melting of glaciers and ice caps is causing sea levels to rise. Extreme weather events like hurricanes, wildfires, droughts, and heatwaves are becoming more common. Some areas are getting more rainfall than usual, while others are experiencing longer dry spells.The timing and lengths of the seasons are shifting too. Winters may be milder with less snowfall. Spring arrives earlier, fall comes later, and summer temperatures keep hitting record highs. Scientists have lots of evidence showing these changes are happening at a rapid pace.So what does this mean for us kids? Well, the effects of climate change make our future pretty uncertain and scary. We may not get to enjoy the same four seasons and typical weather that lots of generations before us did. That's why it's so important for everyone to do their part to reduce emissions and take care of our planet!Every little bit helps, from walking or biking instead of driving, to recycling, and conserving energy. We're the ones who are going to inherit this Earth, so we need to be the change. Nagging our parents to make eco-friendly choices can turn us into great Environmental Protectors! Our future depends on it.Well, that's the scoop on seasons around the world and why climate change is causing some pretty wacky weather these days. I'd give anything to see the Northern Lights or experience an actual snowy winter just once. But I also want to make sure kids years from now can have amazing seasonal adventures too. What's your favorite season?篇3The Seasons Around the World and Global WarmingHi, my name is Tommy and I'm going to tell you all about the seasons in different places on Earth. I've been learning a lot about it in school and I think it's really interesting!First, let me explain what seasons are. Seasons happen because of the way the Earth tilts and moves around the Sun. When the North Pole is tilted towards the Sun, we get summer in the northern half of the world. And when the South Pole tilts towards the Sun, the southern countries get their summer.In places like the United States, Canada, Europe and Russia, we have four seasons - winter, spring, summer and fall (or autumn). Winter is the coldest season with snow, spring has rain and flowers blooming, summer is hot and sunny, and fall has cooler weather with leaves changing colors and falling off trees.But not everywhere has these four seasons! In places closer to the equator like Colombia, Kenya and Indonesia, they only have two main seasons - a dry season and a wet season. The dry season is sort of like summer where it's hot and sunny most days. And the wet season is rainy with thunderstorms, kind of like our spring.Some countries that are really close to the equator like Singapore and Ecuador don't really have different seasons at all. It's pretty much warm and humid all year round!Then you have places at the very top and bottom of the world like Antarctica, Greenland and the Arctic. These polar regions just have one season that is super cold and dark for most of the year. Sometimes it can stay dark for months at a time in the depths of their winter!So as you can see, the seasons vary a lot depending on where you live on the globe. But no matter where you are, the seasons are caused by the Earth's movement around the sun. Pretty neat, right?Okay, now I want to talk about something kind of scary that is affecting seasons and weather patterns all over the world - global warming. Have you heard about that? Global warming refers to the Earth's temperatures slowly getting hotter overall.There are a few reasons why global warming is happening. One big cause is all the factories, cars and planes releasing gases into the air that trap heat from the sun. Another reason is that we are cutting down too many trees that help absorb those gases.So what does global warming mean for the seasons? Well, for one thing it can make winters milder and shorter in a lot of places. You might get less snow than usual. And summers can become extremely hot, with more droughts, wildfires and heat waves.The changing temperatures affect animals too. Some species are going extinct because their habitats are getting too warm for them. Polar bears are a good example - the Arctic ice they live on is melting rapidly.Extreme weather is another consequence of climate change. We are seeing more powerful hurricanes, flooding from heavy rains, and severe droughts in some areas. It's pretty scary!So what can we do about global warming? Well, we need to find ways to use less fossil fuels like gas, oil and coal that make those heat-trapping gases. We should drive less, turn off lights when not using them, and get energy from cleaner sources like solar and wind power.Every family can help by reducing waste, reusing things when possible, and recycling things like bottles, cans and paper. We can also plant more trees since they absorb carbon dioxide and give us clean oxygen.If we all make an effort, we can slow down global warming and help protect the environment. The seasons and weather patterns are so important for all life on Earth. We need to take care of our planet before it's too late!Well, that's all I wanted to say about the seasons around the world and climate change. I tried to explain it in a simple way, but it's actually a pretty complex topic. I'm still learning about it myself in school. Feel free to let me know if you have any other questions!篇4The Four Seasons Around the World and Climate ChangeHi, my name is Timmy and I'm going to tell you all about the four seasons in different countries and how the Earth is getting warmer. It's a really important topic that grown-ups are worried about. Let me start by explaining what seasons are.Seasons are the different weather patterns we get throughout the year. There are four seasons: spring, summer, fall (autumn), and winter. The seasons are caused by the tilt of the Earth as it orbits around the Sun. When the North Pole is tilted towards the Sun, we get summer in the Northern Hemisphere and winter in the Southern Hemisphere. Six months later, theopposite happens - the South Pole tilts towards the Sun so the Southern Hemisphere gets summer while we get winter up north.But seasons aren't exactly the same everywhere on Earth. They depend on stuff like how close you are to the equator (the midline of our planet) and factors like mountains, oceans, and wind patterns. Some places have very different seasons while others barely have any seasons at all! Let me tell you about some examples.In the United States and Europe, we have pretty classic seasons. Spring brings warm weather and flowers blooming after the cold winter. Summer is hot and sunny, great for swimming at the beach. Fall has cooler temps, leaves changing colors, and harvesting crops. Winter is freezing with snow, bare trees, and holidays like Christmas. Easy peasy, right?But in the tropics near the equator, like in parts of Africa and South America, there aren't really any seasons. It's kind of warm and humid all year round without a lot of change. The "seasons" are more like dry and rainy periods. So weird!Australia is a funky case because their seasons are flipped from ours. When we have summer up north, they have winterdown under. Their winters are in June, July and August while we're having summer break and going to the pool.India has three main seasons - summer (really hot and dry), monsoon (tons of rain), and winter (cooler and dry). The monsoon is super important for their farms and many festivals celebrate it.Now I want to talk about a big problem that scientists are very worried about these days - global warming and climate change. You've probably heard about it before. Basically, the Earth is gradually heating up and getting warmer overall.This warming is caused by human activities like burning oil, gas and coal for energy, driving cars, and cutting down forests. It releases greenhouse gases like carbon dioxide into the atmosphere. These gases trap heat from the Sun, kind of like a greenhouse, which raises temperatures across the whole planet over time.Climate change is making seasons shift and change in weird ways. Some places are getting hotter summers, milder winters, weird weather patterns, and more droughts, flooding or intense storms like hurricanes. The polar ice caps are melting which can cause sea levels to rise and floods in coastal cities. Plants, animals and people all get impacted in different ways.Many scientists agree that limiting climate change is really important so we don't totally disrupt the normal seasonal patterns that plants, animals and humans need to survive. We need to find better ways of getting energy that don't pollute as much. Governments, companies and people can do stuff like:Use more renewable energy like solar, wind and hydro instead of fossil fuelsDrive electric cars or use public transportationReduce, reuse and recycle to create less wastePlant more trees to absorb carbon dioxideBuild homes and buildings that don't waste energyEat less meat and dairy since cows create a lot of methane gasThere's still a lot of debate around climate change and what to do about it. But most adults seem to agree that we need to take action to protect the environment and prevent further shifts in seasonal patterns across the world. We kids have to inherit this planet someday so we better start taking good care of it now!That's my essay explaining the four seasons globally and the impact of climate change. I tried to make it easy for kids tounderstand but also accurate based on what scientists say. Let me know if you have any other questions!篇5The Seasons Around the World and Global WarmingHi there! My name is Alex and I'm going to tell you all about the four seasons in different countries and how global warming is changing the seasons. It's a big topic, but I'll do my best to explain it in a way that's easy to understand. Let's get started!First up, the four seasons - winter, spring, summer and fall (or autumn if you prefer). You might think the seasons are the same everywhere, but that's not quite true. While most places have four seasons, the timing and what happens during each season can be really different depending on where you live.In places like the United States, Canada, Europe and parts of Asia, the four seasons are most like what you probably picture. Winter is cold and snowy, spring is warmer with rain and flowers blooming, summer is hot and sunny, and fall is cooler with changing leaf colors.But in other parts of the world, the seasons can look very different. Let me give you some examples from around the globe:AustraliaSince Australia is in the southern hemisphere, the seasons are flipped compared to the northern hemisphere. That means their summer is during our winter (December-February) and vice versa. In summer, much of Australia gets blazing hot with temperatures over 100°F! Winters are mild, with c ool temps and some rain.Amazon RainforestCountries in the Amazon like Brazil, Peru and Colombia really only have two seasons - a dry season and a rainy season. The dry season has lower rainfall and lasts around 4 months. Then the crazy rainy season hits with huge thunderstorms almost every day!AntarcticaAt the very bottom of the globe, Antarctica basically has one ultra cold season all year long. Temperatures can dip way down to -100°F or worse in the winter months of June-August. During their summer (December-February), it warms up a tiny bit with temps around 0°F. But it's still freezing all the time!IndiaIn India, they also generally have three seasons instead of four. Winter is mild, summer is scorchingly hot (over 110°F in some areas!), and then they have a monsoon season of intense heavy rains that can cause flooding.So as you can see, what we think of as the "normal" four seasons of winter, spring, summer and fall really varies a lot based on location and hemispheres. It's one of the coolest things about our amazing planet!But now I need to tell you about something not-so-cool that is happening on our planet: global warming. Have you heard about it? Basically, the Earth's overall temperature has been slowly getting hotter and hotter over the past 100 years or so.There are a few main reasons why global warming is happening. One is that humans have been releasing tons of greenhouse gases into the air by burning fossil fuels like oil, gas and coal. Greenhouse gases like carbon dioxide and methane get trapped in our atmosphere and act like a blanket, trapping in heat from the sun.Another reason is deforestation - we've been cutting down millions of trees in rainforests and other areas. Trees are awesome because they absorb carbon dioxide and releaseoxygen. With fewer trees, more of that heat-trapping carbon dioxide builds up.So what does global warming have to do with the seasons? Well, as the Earth's temperature rises, it's starting to mess up normal seasonal patterns in a lot of places. Let me give you some examples:Winter seasons are getting shorter and less cold/snowy in many areasSpring is arriving earlier than usual with early bloomsSummers are becoming extremely hot, with more heat waves and droughtsFall/autumn is coming later, with delay in leaves changing colorAnimals are going into hibernation later or not hibernating at allPlant and animal species are shifting where they live to find better temperaturesSome areas are being impacted way more extremely by warming temperatures. Polar regions like the Arctic are heating up much faster than the rest of the world. Huge amounts ofArctic sea ice and glaciers are melting at scary speeds, causing sea levels to rise. This melting ice is also disrupting the annual seasons and life cycles that polar bears, seals, penguins and other Arctic animals depend on.Low-lying islands and coastal cities are also in big trouble from rising seas caused by melting ice and warmer ocean temperatures. Their normal seasonal weather patterns are getting extreme storm surges, coastal flooding, and erosion that could make some areas unlivable in the coming decades if we don't reduce global warming.Scientists are really worried that if we humans don't make big changes soon to reduce our greenhouse gas emissions and stop warming trends, we could see even crazier changes to the seasons all over the world. Disruptions to food supplies, water shortages, animal extinctions, and bigger natural disasters are just some of the risks.So what can we do to help? Well, we all need to try our best to have a smaller carbon footprint - that means reducing our emissions in simple ways like:Walking, biking or taking public transportation instead of drivingTurning off lights/electronics when not using themRecycling and trying to create less wasteEating more plant-based foods since livestock create methanePlanting trees wherever possible since they absorb CO2Using renewable energy like solar/wind powerEvery little bit helps! And we need grown-ups to make smart choices for our planet too, like switching to cleaner energy sources, investing in green technologies, and passing laws to limit emissions.If we all work together, we can get global warming under control and make sure humans and animals can keep enjoying the changing seasons for a long, long time. The seasons are one of the coolest, most special things about our planet Earth - and it's our job to protect them!Whew, that was a ton of information! But I hope it helped you understand more about why the seasons vary around the world, how global warming is affecting seasonal changes, and what we can do about it. Let me know if you have any other questions!。
关于美国天气的英语短作文的
关于美国天气的英语短作文的全文共3篇示例，供读者参考篇1The weather in the United States varies greatly depending on the region and time of year. From the sunny beaches of California to the snowy mountains of Colorado, there is no shortage of diverse climates to experience across the country. In this article, we will explore the different types of weather that can be found in the United States and how they impact the daily lives of its residents.On the east coast, states like New York and Florida experience four distinct seasons throughout the year. Summers can be hot and humid, with temperatures reaching into the 90s and frequent thunderstorms. In contrast, winters can be cold and snowy, with blizzards causing travel disruptions and school closures. Spring and fall offer milder temperatures and blooming flowers, making them the most pleasant times of year in these regions.In the central part of the country, states like Texas and Illinois often experience extreme weather conditions. Tornadoes are acommon occurrence during the spring and summer months, causing damage to homes and businesses. In the winter, blizzards and ice storms can make travel treacherous and lead to power outages. Despite these challenges, residents in these regions are accustomed to adapting to the changing weather patterns.In the western part of the country, states like California and Arizona enjoy mild and sunny weather throughout much of the year. However, they also face the risk of wildfires during the dry summer months. In recent years, wildfires have become more frequent and destructive, causing widespread damage to homes and forests. In response, residents have implemented evacuation plans and fire prevention measures to protect themselves and their communities.Overall, the weather in the United States is as diverse as its landscape. From the arid deserts of Nevada to the lush forests of Washington, each region offers a unique climate that shapes the way of life for its residents. Despite the challenges posed by extreme weather events, Americans have shown resilience and resourcefulness in the face of adversity. As the climate continues to change, it is more important than ever for communities tocome together and work towards sustainable solutions that mitigate the impact of severe weather on our planet.篇2The United States is a vast country with diverse weather patterns that vary greatly from region to region. From the cold winters of the northern states to the hot summers of the southern states, the weather in the U.S. can be unpredictable and sometimes extreme.In the northern states such as Alaska, Minnesota, and Maine, winters are long and cold with heavy snowfall. Temperatures can drop well below freezing, and blizzards are not uncommon. Residents in these states often have to bundle up in layers of clothing and stay indoors to stay warm.In the central states like Kansas, Nebraska, and Oklahoma, the weather can be more unpredictable with frequent changes in temperature. Tornadoes are a common occurrence in these states during the spring and summer months, causing widespread damage and destruction.In the southern states such as Florida, Texas, and California, the weather is generally warm and sunny throughout the year. Summers can be scorching hot with temperatures reaching over100 degrees Fahrenheit, while winters are mild with occasional rain showers. Hurricanes are also a threat in states along the Gulf Coast, bringing strong winds and heavy rainfall.The western states like Arizona, Nevada, and Colorado experience a desert climate with hot summers and mild winters. Droughts are common in these states, leading to water shortages and wildfires.Overall, the weather in the United States is diverse and ever-changing, making it important for residents to stay informed and prepared for whatever Mother Nature may bring. Whether it's snowstorms in the north, tornadoes in the central states, hurricanes in the south, or wildfires in the west, Americans must be ready to adapt to the weather conditions in order to stay safe and secure.篇3The weather in the United States is known for its diversity and extreme variations. From the freezing temperatures of Alaska to the scorching heat of Arizona, the weather patterns across the country are as varied as the landscapes themselves.One of the most notable weather phenomena in the United States is hurricanes, which occur predominantly in the Southernand Eastern states. These powerful storms can cause widespread destruction with high winds, heavy rain, and storm surges that can flood coastal areas. States like Florida, Louisiana, and Texas are especially vulnerable to hurricanes, with residents often preparing well in advance for these potentially deadly storms.In the Midwest and plains states, tornadoes are a common occurrence during the spring and summer months. These violent storms can produce devastating winds that can level entire towns and cause significant damage to property. Tornado alley, which stretches from Texas to South Dakota, is particularly prone to these destructive storms.In the western states, wildfires are a major concern, especially during the dry summer months when vegetation is at its most flammable. California, in particular, has seen some of the largest and most destructive wildfires in recent years, with thousands of acres of land being consumed by flames and many homes being destroyed.In the northern states, winter weather can be brutal, with heavy snowfall and subzero temperatures making travel difficult and dangerous. States like Minnesota, Wisconsin, and Michigan often experience blizzard conditions that can shut down roads and airports, leaving residents stranded in their homes.Despite the extreme weather conditions that can be found across the country, the United States also experiences more temperate climates in regions like California, Florida, and Hawaii. These states enjoy mild temperatures year-round, making them popular destinations for tourists and retirees seeking a more relaxed way of life.Overall, the weather in the United States is as diverse as its population, with each region experiencing its own unique climate patterns and challenges. While some areas may be prone to extreme weather events, others offer more moderate conditions that make them ideal places to live and visit. Whatever the weather, one thing is certain – Americans are resilient and always ready to face whatever Mother Nature throws their way.。

Throughout much of human history, man has been the measure of many, if not all, things. Lengths were divided up into feet and smaller units from the human hand. Other measures were equally characteristic. Mediterranean traders for centuries used the weight of grains of wheat to define (定义) their units of mass. The Romans used libra, forerunner of the pound, by referring to the weight of a carob (角豆树) seed.The sizes of similarly named units could also differ. The king's foot, used in France for nearly 1, 000 years after its introduction by Charlemagne in around 790 AD, was, at 32.5cm, around a centimeter shorter than the Belgic foot, used in England until 1300.Greek, Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos, Nor was there agreement on such things within countries. In France, where there was no unified (统一的) measurement system at the national level, the situation was particularly terrible. The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south.Although John Wilkins, an Englishman, first put forward a decimal system (十进制) of measurement in 1668, it was the French who in 1799 made it law. The Système International d'Unités (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shake-up yet.At a meeting in Versailles, France, on November 16th, 2018, the world's measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常数).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20th2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.（1）What does Paragraph 1 mainly tell us?A.Pound went before libra in measurement.B.Different things used to be adopted as measures.C.Grains were accepted as measures by the Romans.D.Fixed measurement systems were gradually formed.（2）How does the author develop the second paragraph?A.In time order.B.By analysis.C.In space order.D.By comparison.（3）Which of the following countries used SI as an official measurement?A.France.B.Liberia.C.America.D.Myanmar.（4）What will the world's measurement bodies achieve at the meeting held in Versailles?A.They will come up with seven new SI units.B.They will set May 20th as a new international festival.C.They will redefine four SI units including the kilogram.D.They will decide on a new measure used in the laboratory.【答案】（1）B（2）D（3）A（4）C【解析】【分析】本文是一篇说明文，法国凡尔赛宫举办的国际计量大会，将对目前使用的国际单位制中的四个基本单位进行重新定义，其中包括对千克的重新定义。

Even the busiest government official or (16) executive always takes (17) extra time to be polite and offer (18) refreshments. No matter how busy you are, you should make time for this (19) hospitality. Making decisions quickly is not an Arab custom. There is a (20) vagueness in doing business in the Middle East which will puzzle a (21) newcomer. Give yourself lots of time and ask lots of questions.Patience is an important (22) quality. You may have to wait two or three days to see high level government officials as they are very busy. Give yourself enough time.Personal relationships are very important. They are the key to do business in Arab countries.(23)Try to identify the decision maker regarding your product or services immediately and get to know him on a friendly basis. Do your homework. Be prepared to discuss details of your product or proposal. Be ready to answer technical questions.When an Arab says yes, he may mean “maybe". When he says maybe, he probably means "no". You will seldom get a direct "no" from an Arab because it is considered impolite. Also, he does not want to close his options. Instead of "no", he will say "inshalah" which means, "if God is willing,,.(24)On the other hand, “yes" does not necessarily mean "yes" . A smile and slow nod might seem like an agreement, but in fact, your host is being polite. An Arab considers it impolite to disagree with a guest.Section DAnd now for the Monday Morning weather report. Right now the skies over the Chicago area are sunny and clear.

热点41 冰川及其与气候的关系(原卷版)中考英语考前时事热点话题阅读
备战2022年中考英语考前时事热点话题阅读+题型专练热点41 冰川及其与气候的关系一、阅读理解1The world’s glaciers are melting（融化）quickly. Scientists, from Nature studied 20 years of satellite data of the world’s 220,000 mountain glaciers, and found that since 2015, glaciers have last 298 bill ion metric tons of ice and snow per year. That is 31% more than 15 years ago, and enough ice melt to put Switzerland under 7.2 meter of water each year.Scientist say the melting is caused by climate（气候）change. Almost all of the world’s glaciers are melt ing. Half of the world’s glacier melts in the United States and Canada. Some miller glaciers are totally lost. The melting “mirrors” the worldwide increase in temperature and is from the burning of coal, oil and gas.Shrinking（缩小）glaciers are a problem for million is of people who use regular glacier melt for drinking water. Very fast melting can also cause floods（洪水）in places like India. But the biggest problem to the world is rising sea levels, Glaciers are responsible for 21% of sea level rise. Mark Serreze, director of the American National Snow and Ice Data Center（NSIDC）in Colorado, thinks that sea level rise is going to be a bigger and bigger problem, as we move through the 21st century.Scientists said that it could take hundreds of years to regrow melted glaciers. Twila Moon studies glaciers at the NSIDC. “I’m not sure whether the glaciers can regrow even if the planet’s temperature is controlled. We must try to keep much ice possible and slow the speed of glacier melting.” she said.1. According to the passage, glacier melting is caused by ________.A. climate changeB. water pollutionC. sea level riseD. serious floods2. ________ of the glacier melt around the world is in the United States and Canada.A. 21%B. 31%C. 50%D. 80%3. What is the main idea of paragraph 3?A. The world’s glaciers are melting quickly.B. Some smaller glaciers are completely lost.C. The world’s glacier melting causes some problems.D. People need to find ways to deal with glacier meting.4. We can guess that Twila Moon might be ________ about glacier regrowing.A. excited B. surprised C. angryD. worried5. The passage is probably from ________.A. a sports newspaperB. a science magazineC. a story bookD. a travel guide2Antarctica is the coldest, windiest, and emptiest place on Earth. But it is also home to penguins and many kinds of ocean life.The cold weather over millions of years has created a huge layer(层) of ice that covers Antarctica. In some places, the ice is about 20 meters thick. Yet the continent (大陆) is also one of the driest deserts on Earth.Humans have explored the area for decades. The first human to set foot on land in Antarctica is said to be John Davis, a US seal hunter, in 1821. Tourists visit the coast of Antarctica during summer, which is from November to February in the southern hemisphere. They get to see penguins, seals, whales and a beautiful icy view.But who lives and works in Antarctica? They are mostly scientists and those who help them carry out their research.The National Science Foundation(NSF) is a US organization. Polar Programs, which is part of the NSF, supports scientists in both the Arctic and the Antarctic.“Each year, we send more than 100 teams of scientists to our three research stations in Antarctica,” Polar Programs spokesman Peter West said.Some scientists study the movement of glaciers(冰川) or the activity of volcanoes. Others study animals such as whales, seals, birds and fish. There are even scientists looking for dinosaur bones!6. We would NOT describe Antarctica as being ________.A. windyB. greenC. coldD. deserted7. The scientists in Antarctica study ________.a. animalsb. glacier movementc. sailing routed. volcanic activityA. abdB. abcC. acdD. bcd8. Paragraph 3 is mainly about ________ in Antarctica.A. special animalsB. tourismC. scientific findingsD. human exploration9. What would be a good title for this passage?A. Missing glaciers.B. The last dinosaurC. Get to know Antarctica.D. Protect Antarctica.10. We can probably find this story in a ________.A. story bookB. movie posterC. sports reportD. geography magazine3Judy is reading a book which describes 37 endangered natural and cultural treasures in the world. The writer wants the book to be hopeful call to action. Let’s visit some of these places.VeniceThe city of Venice, Italy, has been in danger because of rising sea levels. The situation is worse because of its ancient buildings that were built on a body of water and are slowly sinking (下沉). When the city was built 1,600 years ago, the level of the Adriatic Sea was almost 2 meters lower than it is today.Mount KilimanjaroThe mountain is the highest point in Africa, almost 6,000 meters high. It supports 5 plant areas and many kinds of animals.The ice glaciers (冰川) on it are disappearing very quickly. This is bad for the local natural environ ment and its tourist industry. Also, a valuable record of Glacier National ParkIn the US, the icy blocks in the park may soon completely disappear because of weather change. In 1850, there were about 150 glaciers, but only 26 are remaining today.Scientists predict that all the glaciers will be gone by 2030. Warm temperatures are also threat ening (威胁) many kinds of plants and animals that livethousands of years of weather history will also be in the park.lost if the ice melts (融化).Great Barrier ReefIt’s the largest coral reef (珊瑚礁) in the world.Rising sea temperatures are greatly harming the reef.In some areas, healthy yellow, brown and green reefshave become white. The coral becomes white inwarmer tem perature. Sick or dying coral affects thenatural environment of this special underwater area.Water pollution and visits from careless swimmersand divers also threaten the reef.11. The following treasure is important to the local natural environment EXCEPT_______.A. the city of VeniceB. Mount KilimanjaroC. Glacier National ParkD. Great Barrier Reef12. Why is Mount Kilimanjaro so important?①Because it is almost 6000 meters high.②Because it supports 5 plant areas and many animals.③Because it has a bad effect on nature and local travel.④Because it has a valuable record of long weather history.A. ①④B. ③④C. ②③D. ②④13. Glacier National Park and Great Barrier Reef are in danger mainly because of ________.A. rising sea levelsB. melting iceC. warm temperaturesD. water pollution14. What should we do to protect all the four treasures according to the text?A. Stop people visiting the places.B. Try to stop the earth getting warmer.C. Protect all plants and wild animals.D. Stay away from all kinds of pollution.15. The book is probably called“_______”.A. Interesting PlacesB. Disappearing TreasuresC. Ecosystem of the WorldD. Fun Places around the World4On Feb 9, Brazilian researchers at Seymour Island reported a temperature of 20.75℃ on the icy continent of Antarctica. It was almost a full degree higher than the previous record of 19.8℃, taken on Signy Island in January 1982.This record-breaking reading was taken at a monitoring (监测) station in the northern part of Antarctica. According to Brazilian soil scientist Carlos Schaefer, the temperature was documented during a 20-year-long research project. The focus of this project is to study the effect that climate change has on the permafrost (永久冻土) within the region. Permafrost is soil that stays frozen for at least two years. Although this is a first record high for Antarctica, Schaefer stressed that “We can’t use this to anticipate (预测) climati c changes in the future. It’s simply a signal that something different is happening in that area.”But in fact, the last high temperature reading was in the 19℃ range. These higher temperatures can cause ice and glaciers (冰川) in Antarctic regions to melt. The Antarctic peninsula (半岛) —the long finger of land(狭长地带) that stretches towards Argentina（阿根廷）—is most dramatically affected. Scientists saw glaciers that have retreated by more than 100 meters in Discovery Bay where the snow melted in little more than a week, leaving dark exposed rock. This melted ice leads to a rise in sea levels that can threaten the safety of coastal areas. It’s believed to be behind an alarming decline of more than 50 percent in chinstrap penguin (帽带企鹅) colonies, which are dependent on sea ice.Like American writer Ernest Hemingway once said, “The Earth is a fine place and worth fighting for.” We should do everything we can to help save our planet. Otherwise, it may become too hot for us to fix.16. What did Brazilian researchers report on Feb 9?A. Signy Island is the warmest region in the Antarctic.B. Antarctica hit a record high temperature of 20.75℃.C. The average temperature of Antarctica ranges from 19.8 C to 20.75℃.D. Antarctica’s new record temperature is a full deg ree higher than the previous decade.17. What’s the main purpose of the 20-year-long research project?A. To predict possible climatic change in the future.B. To monitor Antarctica’s contributions to world climate change.C. To explain why the permafrost may cause glaciers to melt.D. To examine how the permafrost is influenced by climate change.18. What does the underlined word “retreated” probably mean?A. Moved backward.B. Increased in size.C. Covered a certain areaD. Stretched in an opposite direction.19. According to the text, the melted glacier may lead to________.A. the pollution of ocean waterB. the release of various virusesC. threats to penguin habitatsD. disappearances of coastal cities二、阅读还原阅读短文及文后选项，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。
