高中英语必修7Unit 4 The underground in the world-Task
Unit 4 The underground in the worldTask Writing an e-mail to give informationThis section consists of a series of activities which provide you with an opportunity to practice your listening, speaking, reading and writing skills. The task is divided into three steps and each step is preceded with a skills building activity. Through the three steps, you will learn how to listen to instructions, how to find out different information and how to give reasons for your choices. You are expected to apply what you learn in the skills building sections to write an e-mail to give information about the travel to Dalian.Skills building 1: listen to instructionsIn this part, you will learn how to listen to instructions.T: What sentence structures are often used to give instructions?S: You should …/ You will need to…/ You will have to…Quite good. Now let’s read the guidelines and the key structures in this part. You will know what you should focus on when listening to instructions.Step 1: taking notes for future actionPart AT: If you are going somewhere for holiday, what do you need to plan?S: Where to go, when to go there, how to go there, how much money to spend, who to go with, what to do there and so on.T: Let’s come to the context of Part A. Two families are planning their May Day holiday trip to Dalian. Read the notes before you listen to the recording and make sure that you know what you should listen for.Now I’ll check the answers with you.Part BNow let’s listen to the conversation in Part B and find out advantages and disadvantages of taking different means of transport. Find out why they do not choose to go by aetoplane.Now let’s check our answers.Part CLet’s read the information on the web page about Dalian in Part C on page 59. Compare the information about different means of transport and to complete the notes below the passage.Skills building 2: finding out different informationT: If you are going somewhere, what information should you know before you go on the trip?S1: which way to travelS2: the timetable for the transportS3: travel timeS4: travel costS5: the number of changes needed……Read the guideline in this part first. Then read the questions and the information in the chart. If the question is not complete, you should complete the question first.Step 2: buying ticketsNow you have decided to go to Beijing and then Dalian by train, and you are goingto buy the tickets for the fastest train. Work in pairs, with one person selling tickets and the other as the person who wants to buy the tickets. The student who is going to buy the tickets should ask the ticket seller some questions to decide which train should be taken. Remember to choose the fastest train within the budget. Do you still remember how much money can be spent on the tickets for you all?Work in pairs to make up a dialogue. Some of you will be asked to present your dialogue to the whole class.Now complete the notes below the timetable.Skills building 3: giving reasons for your choicesBoys and girls, you are asked to write an e-mail to explain the reason why you have made the decision. Do you know what you should explain and how to explain your decisions? Now read the guidelines in this part.Step 3: writing an e-mail to your uncle1. First discuss what you should write in the e-mail according to the information gathered in steps 1 and2. You can write an outline to organize your reasons in the e-mail to help you write it well. You can take the following as an example.What to writethe decision: travel by trainthe reasons: why to travel by train;why not to travel by boat or by coach or by planethe decision: which trains to takethe reasons: why to take the chosen trains, considering travel time and travel allowance2. Now begin to write your e-mail. Then some of you will be asked to present your e-mails to the class. If you have some difficulties, you can discuss in pairs.Step 4: Practice:A. Read the passage about the importance of transportation and fill in the chart. Have you ever thought about how important transportation is to the world? Without transportation modern life could not exist. We have come to depend on the availability (可用性) of three principal kinds of transportation.Automobiles, railroads, trucks, and pipelines are the principal means of land transportation. Ships, barges, and submarines (潜水艇) form the chief means of water transportation. Without our principal means of air transportation, the airplane,we would have to slow down our lives and commerce. Nearly every major city in theworld provides some form of public transportation. The most common form of transportation is the bus. Buses have been in use in majorcities since approximately 1900. They provide transportation service on innumerable(无数的) routes from the city center to the suburbs and even to outlying rural areasthat surround the city. Subwaysare mostly found in larger cities, such as New York, London, Beijing, Paris, Sydney,and Tokyo. The subway is an underground system of high speed trai ns. The world’sfirst system was built in London, and trains have been operating there since 1890.Subway trains move more quickly and efficiently than buses. They, too, areinexpensive and help solve city traffic problems. The one drawback of subway trainsis that they are often crowded and noisy. Taxicabs are more expensive than busesor subways, but they deliver you to the exact location you want in the shortest timepossible. Taxis are convenient if you are in a hurry or if you are taking along anumber of suitcases or packages. And as an added attraction, many cab drivers willtell you stories about their adventures as taxicab drivers or even the details oftheir life stories. If you ever visit a major city in anothercountry, you probably have no trouble getting around. You will quickly find out aboutcity bus routes and schedules, and about crowds on subway trains. Like many people,of course, you may come to the conclusion that the most inexpensive and reliableform of transportation will be your own two legs.B. Tom is writing a letter to a newspaper editor, telling him his opinion about whathe saw this morning. Please complete the letter by filling each blank with one properword.Dear Editor,This morning, I saw many cars (1) ____________ for the traffic lights at the (2)____________ road when a large number of people came to the cars.

新教材高中英语课时作业7Unit11PartCLesson2北师大版选择性必修第四册(含答案)
新教材高中英语北师大版选择性必修第四册：课时作业(七) Unit 11Part C Lesson 2 Dealing with ConflictⅠ.阅读理解AFor years, the giant squid (大王乌贼) had remained a modern mystery. Living in the dark depths of the ocean, the creature is difficult for scientists to observe directly. It had also managed to avoid all attempts to film it. That changed last July: for the first time ever, scientists were able to catch the giant squid on video in its natural habitat. They were amazed by what they saw. The scientists filmed the squid in the North Pacific Ocean, south of Tokyo, Japan. They followed it down to a depth of 2，952 feet. They shot more than 23 minutes of video before the squid swam off into even darker depths, The video footage will be released to the public later this month on TheDiscoveryChannel.Tsunemi Kubodera, a zoologist at Japan's National Museum of Nature and Science, led the team that filmed the squid. The team went into the ocean in a small submarine with lights invisible to both humans and squid. Since giant squid eat smaller squid, the scientists released a small squid as bait (诱饵). Then the scientists waited in the pitch black for the giant squid to approach.The color video shows the creature floating vertically, eating the bait squid. The giant squid is 9 to 10 feet long and is missing its two longest tentacles (触须). With those tentacles, it could have measured up to 26 feet long. It has huge black eyes, the size of dinner plates. “It was shining and so beautiful，” Kubodera said.Because the deep ocean is so unfriendly to humans, little is known about the giant squid. Scientists say catching the mysterious creature on video is an important step toward understanding it. For centuries, sailors had reported seeing a huge, oceandwelling beast, thought to be the giant squid. The creature is also believed to be the subject of the Nordic myth of the kraken, a sea creature that supposedly attacked ships in Scandinavian waters over the past thousands of years.1．Why is it difficult to film the giant squid?A．Because it is illegal to film the giant squid.B．Because it is too expensive to make such a film.C．Because the giant squid lives in the dark deep ocean.D．Because the giant squid is dangerous to humans.2．We can learn from the first paragraph that scientists ________．A．first saw the giant squid in the oceanB．discovered a new sea creature in the oceanC．have the ocean bottom secretly recorded on videoD．have first caught the legendary giant squid on video3．According to the passage, the giant squid's longest tentacles can be ________．A．16 to 17 feet longB．9 to 10 feet longC．more than 26 feet longD．about 36 feet long4．The scientists released a small squid in the ocean to ________．A．increase the number of the giant squidB．trick the giant squid into coming outC．make an educational film about itD．show concern for the giant squidBWith climate change and overfishing threatening our oceans, it is becoming increasingly important for researchers to closely observe and check sea animals and plants. However, it's almost impossible to make it since human presence scares the animals. Now, thanks to the robot, aka SoFi, researchers may be able to solve the problem.Built by MIT's laboratory，the snowwhite remotecontrolled robot simulates fish, complete with a flexible tail that moves from side to side and two “fins (鳍)”．When the robot is under the sea, a motor is pumping water into a pair of balloonlike rooms located in the robot's tail. These rooms operate similarly to the key parts in engines. As one room expands, the tail bends to one side; when the motor pushes water to the other channel, the tail bends in the other direction. Thus the robot gains the ability to move to where it wants to go.SoFi solves many of the issues that have affected the usefulness (有效性) of previous robots—some types of autonomous underwater vehicles (AUVs).AUVs traditionally often have had to be tied to a boat because radio frequency communications do not work well underwater. So researchers use sound waves. The new technology can travel greater distances, allowing drivers, by using a controller，to pilot SoFi from up to 50 feet away. SoFi can move around the ocean, unaffected by ropes. Also limiting traditional AUVs' usefulness is the risk of hitting something，like hard stones. With the outside made of rubber (橡胶) and plastic that can keep its builtin electronics dry, SoFi can efficien tly avoid hitting. So a soft robot is more likely to survive a potential crisis.During test dives in Rainbow Reef, SoFi swam alongside the unsuspecting (无疑心的) ocean life at depths of 50 feet for up to 40 minutes at a time，obtaining highquality photos and videos. More importantly, it was able to do so without causing any disturbance. Researchers say sometimes the fish would swim alongside the strangelooking robot in curiosity, while at other times they appeared to completely ignore its existence. “It's no t perfect, but we're improving it. Our efforts will pay off，” says Robert Katzschmann.5．The robot SoFi is created to ________．A．observe climate changeB．help to monitor sea creaturesC．catch fish and observe themD．prevent overfishing in oceans6．Wha t does the underlined word “simulates” in Paragraph 2 probably mean?A．Is modeled after. B．Is designed for.C．Is combined with. D．Is applied to.7．What's Paragraph 3 mainly written to show?A．The shape of SoFi.B．The application of SoFi.C．The structure of SoFi's tail.D．The theory of SoFi's movement.8．What's Robert Katzschmann's attitude towards SoFi?A．Satisfied. B．Negative.C．Hopeful. D．Neutral.Ⅱ.完形填空Troy longed to be a professional basketball player. He had loved the __1__ ever since he was a small child. He was also very skilled.

That question is “What’s your name?” Ever yone gives a different answer, but everyone is correct.Have you ever wondered about people’s names? Where do they come from? What do they mean?People’s first names, or given names, are chosen by their parents. Sometimes the name of a grandparent or other member of the family is used. Some parents choose the name of a well-known person. A boy could be named George Washington Smith; a girl could be named Helen Keller Jones.Some people give their children names that mean good things. Clara means “bright”; Beatrice means “one who gives happiness”; Donald means “world ruler”; Leonard means “as brave as a lion”.The earliest last names, or surnames, were taken from place names. A family with the name Brook or Brooks probably lived near brook(小溪)；someone who was called Longstreet probably lived on a long, paved road. The Greenwood family lived in or near a leafy forest.Other early surnames came from people’s occupations. The most common occupational name is Smith, which means a person who makes things with iron or other metals. In the past, smiths were very important workers in every town and village. Some other occupational names are: Carter— a person who owned or drove a cart; Potter—a person who made pots and pans.The ancestors of the Baker family probably baked bread for their neighbors in their nativevillage. The Carpenter’s great-great-great-grandfather probably built houses and furniture.Sometimes people were known for the color of their hair or skin, or their size, or their special abilities. When there were two men who were named John in the same village, the John with the gray hair probably became John Gray. Or the John who was very tall could call himself John Tallman. John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.Some family names were made by adding something to the father’s name. English-speaking people added–s or –son. The Johnsons are descendants of John; the Roberts family’s ancestor was Robert. Irish and Scottish people added Mac or Mc or O. Perhaps all of the MacDonnells and the McDonnells and the O’Donnells are descendants of the same Donnell.56. Which of the following aspects do the surnames in the passage NOT cover?A. Places where people lived.B. People’s characters.C. Talents that people possessed.D. People’s occupations.57. According to the passage, the ancestors of the Potter family most probably _______.A. owned or drove a cartB. made things with metalsC. made kitchen tools or containersD. built houses and furniture58. Suppose an English couple whose ancestors lived near a leafy forest wanted their new-born son to become a world leader, the baby might be named _______.A. Beatrice SmithB. Leonard CarterC. George LongstreetD. Donald Greenwood59. The underlined word “descendants” in the last paragraph means a person’s _____.A. later generationsB. friends and relativesC. colleagues and partnersD. later sponsorsBIt is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness(荒野)For Killing WolvesIn Alaska，the wolf almost disappeared a few years ago，because hunters were killing hundreds 0f them for sport .However．1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur．So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply．A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food．Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life．When the deer can’t find enough food，they die．If the wolves continue to kill large numbers of deer，their prey(猎物)will disappear some day．And the wolves will．too．So we must change the cycle of life in the wilderness to balance the ecology．If we killed more wolves，we would save them and their prey from dying out．We’d also save some farm animals．In another northern state，wolves attack cows and chickens for food．Farmers want the government to send biologists to study the problem．They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population．Against Killing WolvesIf you had lived long ago，you would have heard many different stories about the dangerous wolf．According to most stories，hungry wolves often kill people for food．Even today，the stories of the “big bad wo lf'＂will not disappear．But the fact is wolves are afraid of people．and they seldom travel in areas where there is a human smell．When wolves eat other animals，they usually kill the very young．or the sick and injured .The strongest survive .No kind of animal would have survived through the centuries if the weak members had lived．And has always been a law of nature.Although some people say it is good sense to kill wolves，we say it is nonsense! Researchers have found wolves and their prey living in balance．The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life．The real problem is that the areas where wolves can live are being used by people．Even if wilderness land is not used directly for human needs．the wolves can’t always find enough food .So they travel to the nearest source, which is often a farm．Then there is danger．The “big bad wolf” has arrived! And everyone knows what happens next．60．According to the passage，some people in North America favor killing wolves for all the following reasons EXCET that ．A. there are too many wolvesB. they kill large numbers deerC. they attack cows and chickens for foodD. they destroy the wilderness plant life61．Some people are against killing wolves because ．A. wolves help to keep the ecological balance in the wildernessB. there is too small a wolf population in the wildernessC. there are too many deer in the wildernessD. wolves are afraid of people and never attack people62．According to those against killing wolves，when wolves eat other animals，．A. they never eat strong and healthy onesB. they always go against the law of natureC. they might help this kind of animals survive in natureD. they disturb the ecological balance in the wilderness63．The last sentence “And everyone knows what happens next” implies that in such cases ．A. farm animals will be in danger and have to be shipped awayB. wolves will kill people and people will in turn kill themC. wolves will find enough food sources on farmsD. people will leave the areas where wolves can live高二暑假英语自修材料答案Keys:Part I:一. 1.purchased 2.privilege 3.anniversary 4.voluntary 5.arrangements6.clinic7.weeds8.relevant9.operated/operates 10.Concept二. 1.of which 2.at which 3.in which 4.provide for 5.to be adjusted三. 1.up to 2. have no concept of 3.making any difference4.from where5.adjust … to…6.dried up7.is dying to8.donate…to…9.Otherwise 10.participate inPart II:1---5.

课时作业7：Unit 4 Astronomy：the science of the stars
Unit 4Astronomy:the science of stars(60分钟83分)Part A一、阅读理解(共9小题;每小题2分,满分18分)AForget cyclists,pedestrians are real dangerWe are having a debate about this topic.Here are some letters from our readers.■Yes,many cyclists behave dangerously.Many drivers are disrespectful of cyclists.But pedestrians are probably the worse offenders.People of all ages happily walk along the pavement with eyes and hands glued to the mobile phone,quite unaware of what is going on around them.They may even do the same thing while crossing a road at a pedestrian crossing or elsewhere.The rest of us have to evade(避让)them or just stand still to wait for the unavoidable collision.The real problem is that some pedestrians seem to be,at least for the moment,in worlds of their own that are,to them,much more important than the welfare of others.—Michael Horan■I loved the letter from Bob Brooks about cyclists(Viewpoints,May 29).I am afraid they seem to think they own the roads.I was walking across Altrincham Road one morning when a cyclist went round me and on being asked what he was doing he shouted at me.The government built a cycle lane on the road but it is hardly used.The police do nothing.What a laugh they are!The cyclists should all have to be made to use the cycle lanes and wearhelmets,fluorescent(发荧光的)jackets and lights at nights and in the morning.They should pay some sort of tax and be fined for not wearing them.—Carol Harvey■Cyclists jump on and off pavements(which are meant for pedestrians),ride at speed along the pavements,and think they have a special right to go through traffic lights when they are on red.I was almost knocked down recently by a cyclist riding on the pavement when there was a cycle lane right next to him.Other road users,including horse riders,manage to obey the rules so why not cyclists?It’s about time they had to be registered and insured,so when they do hit a pedestrian or a vehicle,or cause an accident,at least they can be traced and there might be an opportunity to claim.—JMLWrite to Viewpoints of the newspaper.(2015·湖南高考)1.Michael Horan wrote the letter mainly to show that .A.drivers should be polite to cyclistsB.road accidents can actually be avoidedC.some pedestrians are a threat to road safetyD.walking while using phones hurts one’s eyes2.Carol Harvey suggests that cyclists should .A.be provided with enough roadsB.be asked to ride on their own lanesC.be made to pay less tax for cyclingD.be fined for laughing at policemen3.What is a complaint of JML?A.Very few drivers are insured.B.Cyclists ride fast on pavements.C.Pedestrians go through red traffic lights.D.Horse riders disrespect other road users.4.The underlined word “they” in th e third letter refers to .A.accidentsB.vehiclesC.pedestriansD.cyclists5.The three letters present viewpoints on .A.real sources of road dangersB.ways to improve road facilitiesC.measures to punish road offencesD.increased awareness of road rulesBAn ambitious project to establish a human colony on Mars has attracted applications from tens of thousands of would-be astronauts,just two weeks after applications opened.The mission,a private venture by the Dutch non-profit organization,Mars One,aims to send a crew to the Red Planet in 2022—and,due to the physiological change in the human body after a stay on Mars,there’d be no coming back.That hasn’t deterred people,though,so far,over 200,000 people have applied to become one of Mars’first immigrants.“This is turning out to be the most desired job in history,” says Bas Lansdorp,co-founder of Mars One.Day-to-day life on Mars will be no picnic.The organization says that the daily routine on the planet would involve construction work on the colony (installing greenhouses,forexample),maintenance of the settlement’s systems and research into Mars’climate and geological history—all in an inhospitable environment with unbreathable air and an average temperature in the planet’s mid-latitudes of around -58 ℉.But Mars One says it is not looking for applicants with specific skills,such as a science degree,which might be useful during an interplanetary posting.Instead,they are looking for people who “have a deep sense of purpose,willingness to build a nd maintain healthy relationships,the capacity for self-reflection and ability to trust.” They also want volunteers who are “resilient,adaptable,curious,creative and resourceful.” Candidates will receive a minimum of eight years training before leaving Earth,the company says.In addition to people skills,successful applicants must be good fundraisers too:Mars One plans to raise much of the mission’s $6 billion estimated cost through a reality TV show following the applicants as they undergo preparations for the one-way trip to Mars.1.According to the passage,we can’t know about Mars that .A.there is no human beings living on it nowB.there is no air on itC.the mid-latitudes’average temperature is lower than that on the earthD.it will lead to physiological change for human beings living on it2.The applicants will on Mars.A.live in coldB.get a desired jobC.do some researchD.get a large amount of money3.The applicants are not necessary to .A.have a science degreeB.have people skillsC.be good fundraisersD.have a deep sense of purpose4.The underlined word

lessons.When you choose to be a student of life,you open yourself to limitless opportunities.Explore the world.Don’t limit yourself to your hometown or to the city you got your first job.2It doesn’t

2．下列两种物质不属于同分异构体的是(A)A．淀粉纤维素B．蔗糖麦芽糖C．正丁烷异丁烷D．果糖葡萄糖解析：同分异构体特点：分子式相同结构不同，而淀粉和纤维素属于多糖，分子式不同，故A错误。
3．葡萄糖的结构简式为CH2OH—CHOH—CHOH—CHOH—CHOH—CHO其对应的性质中不正确的是(D)A．与钠反应放出氢气B．可与乙酸发生取代反应C．能发生银镜反应D．可使小苏打溶液冒出气泡解析：葡萄糖含有羟基，故能与钠反应放出氢气，与乙酸发生取代反应；含有醛基，能发生银镜反应；无羧基，所以不与NaHCO3反应，故只有D错误。
4．下列关于淀粉和纤维素的叙述正确的是(D)A．两者都属于糖类，所以都有甜味B．两者化学式相同，所以属于同分异构体C．两者具有相同的通式，所以化学性质相同D．两者碳元素的百分含量相等解析：淀粉和纤维素属于多糖，没有甜味，A项错误；两者常用(C6H10O5)n 表示，但n值不同，分子式不同，结构也不同，所以不属于同分异构体，化学性质也不同，故B、C两项错误。
5．(多选)下列关于蔗糖的说法中，不正确的是(AC)A．蔗糖是最重要的双糖，它的相对分子质量是葡萄糖的两倍B．纯洁的蔗糖溶液中加入银氨溶液，微热，不发生银镜反应C．向蔗糖与稀硫酸共热后的溶液中滴加银氨溶液，再水浴加热能看到银镜生成D．在蔗糖里加入浓硫酸，可观看到颜色变黑，并有气泡消灭解析：葡萄糖的分子式是C6H12O6，蔗糖的分子式为C12H22O11，A不正确；蔗糖分子内无醛基，B正确；蔗糖在酸性条件下水解，但检验其水解产物前必需先加碱调至碱性再检验，C错误；蔗糖加浓硫酸炭化脱水，发生氧化还原反应，有大量气体消灭，D正确。
6．(多选)下列试验结论正确的是(BD)试验操作现象结论A 向淀粉的水解液中加入碘水溶液变蓝淀粉没有水解B将乙醇与酸性重铬酸钾(K2Cr2O7)溶液混合橙色溶液变为绿色乙醇具有还原性C向蔗糖溶液中加入稀硫酸，水解后加入银氨溶液，水浴加热未消灭银镜水解的产物为非还原性糖D将新制的Cu(OH)2与葡萄糖溶液混合加热产生砖红色沉淀葡萄糖具有还原性解析：A项，淀粉未完全水解时，与碘水作用，溶液也会变蓝，错误；B项，乙醇具有还原性，能被强氧化剂K2Cr2O7氧化，正确；C项，在加入银氨溶液之前应先加入碱液中和多余的酸，使溶液呈碱性，错误；D项，葡萄糖具有还原性，正确。
