With his speed and power, he has conquered (征服)lots of other great boxers of the 21st century. In between fights, he keeps his training and strengthens it when another fight approaches.Just like a boxer, we too, come face to face with many competitors in the arena(竞技场)oflife―problems and difficulties. The bad news is that we don't really know when they occur.Here are several reasons why you should train yourself for success like a champion boxer!You don't practice in the arena ; that's where your skills and your abilities are evaluated. This also means that you don't practice solving problems and developing yourself when problems occur; you prepare yourself to face them long before you actually face them.Talent is good but training is even better. Back in college, one of my classmates in Political Science didn't bring any textbook or notebook in our classes ; he just listened and participated in discussions. What I didn't understand was how he became a top student! Obviously, he was gifted with a great memory and analytical skills. In short, he was talented.If you are talented, you maybe need less preparation and training time in facing life's challenges. But even for people who are talented, training and learning are important. Avoid the lazy person's maxim (格言):“If it isn't broken, why fix it?” Why wait for your roof to leak in the rainy season when you can fix it right away?Training enables you to gain intuition (直觉)and reflexes (反应力).Without training, you will mess up. Without training, you won't be able to anticipate how your enemy will hit you. You will lose control of your race car after the first lap. With training, you lower the possibility of these accidents.Keep in mind that training is borne out of self-command and strong will. Even if you meet with some setbacks in your training, if you keep at it and persevere, you will soon see results in your life and when problems come, you will be like the champion boxer who stands tall and fights until the final round is over and you're proclaimed as the champion!24. What does the text mainly tell us?A. To become a top boxer isn't easy.B. We should train ourselves for success.C. Life is full of problems and difficulties.D. Talent is more important than training for success.25. Why does the author mention his classmate?A. To introduce his classmates learning methods.B.T O prove an average person doesn't need more training.C. To prove even talented people also need training.D. To show respect for his classmate.26. Which is the closest in meaning to the underlined word “anticipate” in Paragraph 7?A. predictB. avoidC. understandD. defeat27. What can we know from the last paragraph?A. Victory depends on the positive attitude to training.B. Ifs normal to meet with some difficulties in training.C. Boxers often win the victory by persevering.D. Perseverance in training is very important.CAs with many etymologies(词源),the exact root of this word is difficult to say with one hundred percent certainty. However, the leading theory is extremely believable and backed up by a fair bit of documented evidence. Specifically, it is thought that a dollar is called a “buck" thanks to deer.One of the earliest references of this was in 1748, about 44 years before the first US dollar was created, where there is a reference to the exchange rate for a cast (桶)of alcoholic drink traded to Native Americans being "5 bucks” , referring to deerskins.In yet another documented reference from 1748, Conrad Weiser, while traveling through present day Ohio, noted in his journal that someone had been “robbed of the value of 300 Bucks".At this time, a buck skin was a common medium of exchange. There is also evidence that a "buck" didn't simply mean one deerskin, but may have meant multiple skins, depending on quality. For instance, skins from deer killed in the winter were considered superior to those killed in the summer, due to the fur being thicker. It is thought that the highest quality skins generally had a one to one value with one skin equaling one buck. In contrast, for lower quality skins, it might take several of them to be valued at a single buck. The specific value for given sets of skins was then set at trading. In addition, when the skin was from another animal, the number of skins required to equal a buck varied based on the animal and the quality of the skins. For instance, there is one documented trade where twelve high-quality rabbit skins equaled one buck.This use of skins as a medium of exchange gradually died off over the next century as more and more Europeans moved in and built towns and cities. Once the US dollar was officially introduced after the passing of the Coinage Act of 1792 , it quickly became the leading item used as a medium of exchange, but the term "buck" stuck around and by the mid-nineteenth century was being used as an informal term for the dollar.28. What can be inferred from the text?A. The first dollar was made from a deerskin.B. A skin from any animal was valued at a buck.C. The quality of a deerskin varied with the change of seasons.D. Deerskins were the only medium for trading in 1970s.29. When did the use of skins as a common medium of exchange die off?A. As more and more Europeans settled in America.B. When the Coinage Act of 1792 was passed.C. When the bucks died out in the 1950s.,D. As the US dollar was officially introduced.30. How does the author mainly develop this text? ”A. By analyzing causes.B. By following the order of importance.C. By making comparison.D. By following the order of time.31 . What is the text mainly about?A. When the dollar first appeared.B. Why a dollar is called a buck.C. What a dollar was worth in the past.D. How the word dollar came into being.DA new device works like a solar panel, except it doesn't harvest energy from the sun. It captures energy from the cold night sky.A prototype (雏形)of the device produced enough electricity at night to power a small light bulb. A bigger version might one day light rooms or charge phones. It could also power electronics in remote or low-resource areas that lack electricity.The device makes use of the temperature difference between the earth and outer space to create electricity. As long as one side of it is cooler than the other, the generator can produce electricity. The cooler side faces the sky and is attached to an aluminum plate. That plate is sealed beneath a transparent cover and surrounded with insulation (隔热材料)to keep out heat. The bottom of the generator is attached to an exposed aluminum (铝)plate. That plate is warmed by the local air. At night, the top plate can get a couple of degrees Celsius cooler than the bottom of the generator.Researchers tested a 20-centimeter prototype one clear December night in Stanford University, California. The generator produced up to 25 milliwatts of power per square meter of the device. That was enough power to light a small light emitting diode (发光二极管),or a LED bulb. Further improvements might increase its production to at least 500 milliwatts per square meter. The system might need more insulation around the cool, top plate to do that.“The device could also help power remote weather stations or other environmental de vices, " says Aaswath Raman. He is a material scientist who works on the device at the University of California, Los Angeles. " This may be useful in polar regions where people can't see sunlight for months, “ Raman says. "If you have some low-power devices and you need to power them through three months of darkness, this might be a way. ”32. What does the author mainly talk about in Paragraph 3 ?A. Application fields of the device.B. The developing process of the device.C The working principle of the device.D Significant effects of the device.33 How can researchers make the device produce more electricity? A. By putting more insulation around thetop plate.B. By using it in extremely cold and clear nights.C. By attaching the bottom plate to a warm plate.D. By covering the top plate with a transparent lid.34.What's Raman's attitude to the new device?A. Doubtful.B. Hopeful.C. Negative.D. Ambiguous.35 . What could be a suitable title for the text?A. A Device Using the Cold Night Sky to Produce ElectricityB. A Device Bringing New Hope for Those in the Cold NightC. The Differences Between a Solar Panel and a New DeviceD. The Temperature Difference between the Earth and Outer Space第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

On 14 July.C. On 29 June.D. On 6 July.BWe know that smartphone addiction is real,and that it can affect lives in negative ways.While some people have tried going cold turkey(快速戒掉坏习惯)or even punishing themselves for using their mobile phones,an app is made available in the UK that rewards people for staying away from their devices.The app,called Hold,was created by Norwegians Maths Mathisen,Florian Winder,and Vinoth Vinaya while they are studying at Copenhagen's Business school to help break fellow students' attachments to their devices.The three college students found that positive reinforcement(强化)was the best way of beating smartphone addiction.Hold allows students to collect points for staying off their devices between the hours of 7 am and 11 pm;they get 10 points for every 20 minutes.Through partnerships with universities and businesses,points can be used for discounts on everything from cinema tickets to Amazon goods to cafe food and drink.A half price cinema ticket,for example,costs 60 points,or 2 hours away from a phone.And a £5($6.88)Amazon voucher(代金券)needs 1,000 points,or 33 hours off your smartphone.Students can also use their points to buy school books and stationery(文具),which are then donated to schools partnered with children's charity Unicef.Over 120,000 people use the app in Scandinavia,including 40 percent of higher education students in Norway,where Hold first came onto market in February 2016.It's now available to students from over 170 universities in the UK.A 2017 University of Texas study claimed that merely placing a smartphone in someone's line of sight slowed down their productivity,response time,and reduced their grades.An earlier study from the London School of Economics found students who didn't use smartphones on school grounds saw their test scores increase 6.4 percent.4.The app Hold was created mainly to ______ .A. promote online sales of goodsB. earn discounts on goods or servicesC. find new uses of mobile phonesD. help students put down their smartphones5.How long should a student stay off the mobile phone to get 300 points?______A. 6 hours.B. 10 hours.C. 15 hours.D. 30 hours.6.What is the main purpose of the text?______A. To tell the story of Hold creation.B. To present people's opinions of Hold.C. To give a brief introduction of Hold.D. To attract potential customers to Hold.7.Where is the text most likely to appear?______A. A newspaper advertisement.B. A computer textbook.C. A science magazine.D. An official document.CThe dancer put a cardigan sweater over her leotard.Then she sat down to eat asandwich.Cardigan,leotard,sandwich-where did these words come from?Did you know that each of them was a person's name?Words that come from proper names are called eponyms(名祖名词),and there are many eponyms in English.The sandwich,for example,was named for John Montagu,the Earl(伯爵)of Sandwich.He lived from 1718-1792.He loved to play cards and did not want to stop a game even to eat.By putting cold meat between two pieces of bread,he could eat while he played.The cardigan sweater was named for an officer in the British army.In the 1800s,James Thomas Brudenell,the Earl of Cardigan,spent his own money to buy special knitted(针织的)jackets for the men in his army.Knitted jackets with buttons soon came to be called cardigans.Jules Leotard was a French circus performer.In 1859,at the age of twenty-one,Leotard performed the first mid-air somersault(空翻).He became known as the daring young man on the flying trapeze(吊杠)Leotard invented a close-fitting one-piece suit to wear when he performed.Dancers still call their close-fitting garments leotards.Another person who gave her name to a style of clothing was Amelia Bloomer.Bloomer was the editor of a magazine called The Lily.A men can woman in her day were expected to wear heavy skirts that dragged on the floor.In 1851,a young woman named Elizabeth Smith Miller introduced a new kind of clothing that was much easier to move around in.She wore a dress that came only to the knees.Under it she wore loose pants that fitted close at the ankles.Amelia Bloomer published a picture of the outfit(全套服装)in the Lily.She hoped women would adopt the new style.In news stories,reporters called the pants "bloomers".A hundred years later,people were still using the word.There are many other words that come from people's names.The diesel engine was named for its inventor,Rudolf Diesel.The word boycott comes from the name of an English landlord named Charles Boycott.Where each word came from is a story in itself.Who knows,maybe your name will become a word someday.8.Why did the Earl of Sandwich invent the "sandwich"?______A. He found it boring to play cards.B. He preferred to eat meat and bread.C. He wanted to create a new kind of food.D. He could eat while playing cards without stopping the game.9.According to the text,what do "bloomers" refer to?______A. Loose dresses.B. Loose pants worn under a dress.C. Dresses that came to the knees.D. Heavy skirts dragged on the floor.10.What do the words cardigan,leotard and sandwich have in common?______A. They are still in use today.B.

Words that come from people's names.C. The history of garments development.D. The unknown stories behind English words.DA team of researchers led by engineers from Penn State University has created the first material that heals itself in the presence of water,according to a study published in Scientific Reports.The material,inspired by squid(鱿鱼)teeth,could be used to repair instruments in water-filled environments that are difficult to access,such as the human body,or the bottom of the sea.The researchers had been studying squids' ring teeth,which are uniquely strong and can change state from liquid to solid in the presence of water.After testing ring teeth samples from several species of squid found all over the world,the researchers uncovered the genetic code for the proteins(蛋白质)that allow the teeth to heal themselves when broken.They then changed the genetic structure of bacteria to produce the proteins so they could conduct more tests.The researchers then made the proteins into a rubbery plastic by mixing them with a solvent(溶剂)and letting the solvent change into a gas.The resulting material combines a soft,shapeless part of the protein that gives the plastic its self-healing characteristics and a more structured sheet of amino acids(氨基酸)that give it a solid structure.To test the material's strength,the researchers cut it,and then put the two pieces back together with a drop of water.They found that the material healed best at 113 degrees Fahrenheit,a little warmer than the temperature of the human body,and with slight pressure from a metal tool.The material was just as strong,and able to hold the same amount of weight,before and after it was cut.Material that heals itself in the presence of water could expand the usability of biomedical implants(移植).Of course,this material is nowhere near ready for that application,and the researchers didn't test whether the constant presence of water degrades(降低)the plastic's ability to heal itself.The researchers next plan to study how their technology could help heal wounds.12.According to paragraph 3,the rubbery plastic become self-healing in combination with______ .A. amino acidsB. another kind of rubberC. a mixture of gasesD. some protein13.In paragraph 4,the researchers carried out a test to check whether the material ______ .A. was fit for human bodyB. would melt at high temperaturesC. could be connected with the metalD. would recover its original strength after healing itself14.What is the authors attitude towards the self-healing material?______A. Positive.B. Objective.C. Doubtful.D. Critical.15.What is the main idea of the text?______A. A kind of self-healing teeth was made from squids' ring teeth.B. The genetic code of squids' special teeth has been uncovered.C. Super-strong material inspired by squid teeth is self-healing.D. A special rubbery plastic is used to replace squids' teeth.二、阅读七选五(本大题共5小题,共10.0分)Imagine going to the doctor to get treatment for a terrible fever. (1) .The robot detects(检测)the cause of your fever,travels to the appropriate system and provides medication directly to the infected area.(2) .They're called nanorobots(纳米机器人)and engineering teams around the world are working to design robots that will eventually be used to treat everything from fever to cancer. In recent years researchers have been building nanorobots out of a familiar material - the same stuff that makes human life possible. (3) .DNA is literally all around(and in)you - you just can't see it.If you were to look inside almost any cell inside any living creature,you would find DNA.This might sound surprising-especially since these nanorobots don't need batteries or anypower source.Instead,they work by using the natural structure of DNA.These nanorobots "crawl" on DNA.Sometimes researchers refer to these things as DNA "spiders". (4) .A nanorobot could,perhaps,destroy just a cancerous cell,for example,but leave healthy cells alone.(5) .But the future is bright for DNA-built nanorobots.One day,perhaps DNA-made machines will swim around in the human body,delivering medicine to diseased cells or helping doctors diagnose problems.Or maybe they'll help build the smallest computers the world has ever seen.A.These nanorobots are made of DNA.B.Nanorobots made from DNA aren't useful yet.C.In other words,the DNA nanorobot destroys the track as it goes.D.This description will give you a simple picture of the legs of a DNA nanorobot.E.Being able to make such a tiny thing move in a certain way might be useful for health.F.Instead of giving you a pill or a shot,the doctor puts a tiny robot into your bloodstream.G.In fact,we're not that far off from seeing devices like this actually used in medical procedures.16.

Our task,however,is to keep our expectations,worry,and anger to ourselves and do something positive(积极的)for our children.We must encourage our children to solve their own problems.If you want to help your daughter,the best thing you can do is accept her feelings.I know how hard it is not to do something to help our children with their friend problems,but they willalways refuse our advice.When your daughter comes to you with her complaints,listen without saying a word.Try to see what your daughter is feeling and ignore the words.When you think you know what she is feeling,let her know that you know.She needs to express her feelings and you just allow her to do that.Sit and listen for as long as she wants to talk,or cry.If you need to say something,let her know that her feelings are acceptable.They often need to be encouraged to solve their own problems.We may have to listen for a long time before they move from complaints(抱怨)to problem-solving.They need our support and encouragement but they don't need or want our advice.Trust your daughter to learn and grow from this experience.You will,too.Elaine Gibson13.What does Sarah's daughter complain about?______A.

Education.CIf you walk into a native plant nursery(苗圃),you must feel defeated(被击败的)because all the little plants look similar.Now we have the shopping guide for you:a set of easy-to-carryflashcards that explain in brilliant color what those little plants will look like when they all grow up.Native Plants just aren't that easy to understand for traditional gardeners. "That's why staff(员工)at the Theodore Payne Foundation for Wild Flowers & Native Plants began creating some good information into the world of native plants," said Kitty Connolly. "Everybody needs to learn about natives if we're going to have them in our future,but it's difficult to get information to everyone at once.We wanted something that would be useful to everyone."The group decided to create flashcards only about the size and shape of an iPhone 6. "You can take them apart and put them on a table to see how plants go with other plants.They don't replace a website or great books on the shelf;they're just easier to carry and use for planning," said Mike Evans.While the cards are very small,they include a lot of information.You can find how tall and wide a particular plant will grow,when it blooms,how quickly it grows,what birds and animals it attracts and how much water and sunlight it needs.The cards don't include all native plants.They don't include milkweed,for example.But they are helpful for people to learn native plants.The price of the cards is $17.They are only sold online.If people have the cards,they can more easily request the plants they want.The director said,"We create the cards with the hope that people can learn more about native plants and grow them."17.Why do people feel defeated in a native plant nursery?______A. They're forced to buy many plants.B. The little plants are difficult to carry.C. The little plants have bright colors.D. They can't recognize little plants there.18.How does Mike Evans like the flashcards?______A. They are too big.B. They are easy to carry.C. They are too expensive.D. They are difficult to buy.19.What can we know about the flashcards from the text?______A. They can be bought in a local food store.B. They have a bigger size than an iPhone 6.C. They are helpless for people to learn plants.D. They show information of some kinds of native plants.20.Which is the best title of the text?______A. Flashcards Will Help You Learn Native PlantsB. Native Plants Are Sold OnlineC. Plant Nurseries Won't Grow Native PlantsD. Little Plants Look the SameDIt's likely that you don't think you've invited a spy(间谍)into your home when setting up a new TV.But new Samsung,LG,and Vizio smart TVs can record and share everything that's viewed,whether it's a broadcast or something streaming from the Internet.And some smart TVs can even track what DVD you're watching.Your viewing habits are valuable information for marketers who might want to use the information to advertise(广告)new shows and products,offer extra content on shows you want to watch.The advertisements are like the ones you see on your computer.You might not realize that you allowed TVs to collect your viewing habits when you agreed to the long privacy policy(隐私政策)during setup.With Samsung,there are 47 screens of text.LG and Vizio also ask you to agree to the privacy policy in thousands of words in fine print. When Consumer Reports emailed the makers to ask how they are using thetechnology,representatives(代表)for Samsung and Vizio didn't say anything.An LG representative said that the company isn't using any data to send personalized ads and has no plans to do so.But Consumer Repots says that cold change at any time.You might think,"How can I turn those advertisements off?" It's not always so easy.To stop tracking,you have to fight your way through menu stings.On an LG set,go to settings,then options,then Live plus,click off,then close.With Vizio,it's like a long tour through three menus to turn off the advertisements.With Samsung,it's a similar trip to find the box "SyncPlus and Marketing" to disable it.Consumer Reports says that countermanding the marketing feature may cause you to lose some extra services from makers,but it's more important to protect your privacy.21.What will the marketers use customers' viewing habits to do?______A. Build a good relationship with customers.B. Collect some suggestions about shows.C. Advertise new shows and products.D. Improve the quality of smart TVs.22.How does Consumer Reports think of what the LG representative said?______A. Supportive.B. Doubtful.C. Reasonable.D. Believable.23.What's the main idea of paragraph 5?______A. How we stop advertisements from appearing on the screen.B. How we can get more shows from TV.C. How we send personal information to others.D. How we learn to use TVs' settings.24.Which word can replace the underlined word "countermanding" in the last paragraph?______A. learningB. readingC. researchingD. cancelling三、阅读七选五(本大题共5小题,共10.0分)You want to be loved,respected,and live a happy life.And so do I. (1) However,we aren't taught how to get this.There is no happiness class at school and everyone's definition(定义)of happiness is different.However,there are several key habits that you can develop to be happy people.(2) If happy people are with their kids,they are fully enjoying that moment in time.They aren't thinking about what they will make for dinner or how they will pay for their children's schooling.They hang out with other happy people.It's true that happiness is contagious(会传染的). (3) If you hang out with people that are sad and angry,you're likely to become those people as well.Make sure you surround yourself with happy,positive people that choose to look at the bright side of things.They exercise regularly Exercise is goo for health,both physical and mental heath.You don't need to spend two hours in the gym.Just a thirty-minute walk can be of great benefit to your mental health. (4)They don't seek happiness in things.They know a pair of new shoes or a new car isn't what's going to make them happier. (5) A weekend at the beach with good friends means more to them than a new cellphone.A.They live in the moment.B.We all want the same thing.C.But sadness and anger are contagious too.D.They don't compare themselves to others.E.Most of the time,happiness isn't something we just walk into.F.Instead,happy people value experiences and people above things.G.To get the most out of a workout,simply pick an activity you enjoy.25.

Intrigued by the sight, Chen raised his camera to take a picture of the three — but it was then that he noticed the sleeves of the girl in red blowing in the wind. He approached and touched the girl's sleeves, only to discover there were no arms inside.After returning home and reviewing his photographs, Chen decided he had to find the girl again. Chen finally found the girl one year later. He learned that she touched an exposed electrical wire when she was only 4 and had to have both her arms amputated. It was then that an idea occurred to him — hand in his pictures of Xiang to the World Press Photo Contest, which offers a 10,000 euro ($11,080) top prize. From 2003 to 2013, Chen visited the family and took photos of Xiang every year. He entered the contest every year, but every time he failed to win the top prize. That was until December last year, when his pictures caught the attention of journalists at a photo exhibition. After the photos were published online in June, 2016, they were viewed more than 100 million times and attracted more than 80,000 comments. With the support of the China Social Assistance Foundation, more than 300,000 yuan was donated to Xiang. "She now has more confidence and told me over phone that she wants to open an online store," Chen said.4. Chen Yongheng first met with Xiang Liping when she .A. was taking part in a contestB. was being treated in hospitalC. was traveling with her familyD. had already had her arms amputated5. The underlined word "Intrigued" can be replaced by “”.A. TerrifiedB. AttractedC. ShockedD. Touched6. What can we know about Xiang Liping?A. She lost her arms because of a car accident.B. She will use the donated money to help others.C. Her photos caught great attention of online viewers.D. She opened an online store together with Chen Yongheng.7. What does the passage mainly talk about?A. A photographer helps a disabled girl by recording her life.B. A photographer won the top prize by his strong will.C. A girl who lost her arms lives a hard life.D. One will be rewarded by helping others.CThe new two-child policy is making job hunting more difficult for women when about 40 percent of them said they were asked whether they planned to have a second child during job interviews, according to a report in Chongqing.China dropped its decades-long one-child policy in October and allowed each family to have two children. The country now has about 270 million married women of childbearing age.This change has put millions of career women in a dilemma between family and career. Employers also face big challenges as more female workers will have two childbearing leaves, seven to eight months altogether. A human resources website conducted a survey among 500 employers and 5,000 job seekers about how the two-child policy affects the job market.Though two thirds of employers said the policy would make no difference to their recruitment(招聘), the survey showed that more than 70 percent of job seekers believe that bearing a second child will make women less popular in the job market. Forty percent of employers said they will give priority to married women with two children, according to the survey.Lin Xia, 29, quit her job after giving birth to her first child. She is now preparing to return to work. After several inquiries at a job fair, she found that the employers are concerned aboutfuture birth plans. "I thought it would be easier to find a job after giving birth," she was quoted as saying by the website. "I had to answer whether I will have a second child before I could get a chance for a job interview."Liang Siqi, 23, a college graduate, said although employers did not ask her the child question yet, she will not plan to have two children. "It (having two children) will definitely affect my career and personal life, so I will have only one," she said.Zhou Jiansong, who is in charge of human resources at a large private high-tech group in Chongqing, said the company will discuss birth issues with interviewees in order to make a better work plans. "We fully respect a women's right to bear a child or two," he said. "But you don't want them to go on a childbearing leave soon after they join your company." The experts expect more labor dispute cases concerning childbearing leave rights when bearing a second child in future.8. As for the influence of the new policy on working women, which of the following is TRUE?A. They will find it more difficult to ask for a leave in a companyB. Most of them will be forced to choose to have two childrenC. Many of them will stay at home instead of working outsideD. Those who have two children may find it easier to get a job9. In the opinion of Zhou Jiansong, what will employers probably do when interviewing women interviewees?A. They will pay no attention to women’s right to have a child or twoB. They will let women interviewees make a future planC. They may hope to know more about women interviewees’ childbearing planD. They may expect more labor debate c ases about interviewees’ second-child plan.10. What can we infer from the report in the passage?A. All the women surveyed in the passage are marriedB. The women bearing a second child get the same chance as before to get a jobC. About 70 percent of the women were asked whether they planned to have a second child.D. Bearing a second child affects the women’s career to some degree.11. What is the writer’s attitude towards the new two-child policy?A. PositiveB. NeutralC. IndifferentD. CriticalDWe are often unable to pay close attention to what we hear. Just like when we try to grab a sponge(海绵) that is full of water, some water will run out of it. But sometimes we try to remember everything a speaker says and try to take in a speaker’s every word as if every word was equally important. We try to remember all the names, all the dates, and all the places. In the process we often miss the speaker’s main point.Erik Waldman works at a design company. Knowing he had never been good at budgeting his money, he was determined to begin thinking about his economic future. When his employer circulated an e-mail announcing a financial planning workshop(研讨会), Erik signed up right away.The first session was about retirement planning. Simone Fisher, the lecturer, explained that 7 of 10 Americans between the ages of 22 and 35 do not have a regular savings plan. Erik wrote down every number Simone mentioned."If you want to have a retirement income equal to 75 percent of your current salary," Simone continued, "you will need to save at least of 6 percent of your present earnings, taking into account future inflation rates(通货膨胀率). In the meantime, I want to stress that the most important thing is to start saving now."Erik recorded all the statistics Simone used. When she opened the floor(自由发言) for question, Erik raised his hand and said, "I have two question. When is the best time to start saving for retirement? And how can I figure out my savings target if I don’t know what inflation rates will be in the future?"This is a typical example of losing the speaker’s point by concentrat ing on details. Erik had fixed his mind on remembering all the statistics in Simone’s presentation, but he blocked out the man message. Rather than trying to remember everything, we should concentrate on main ideas and evidence.12. What does the author mean by saying "Just like when we ... run out of it."?A. We tend to reject what others say.B. We always try to remember all details.C. It is difficult for us to remember all things.D. We often fail to focus on what we are listening to.13. During the workshop, Erik .A. got Simone Fisher 's main ideaB. focused on the lecture's detailsC. showed little interest in the lectureD. didn't agree with what Simone had said14. When hearing Erik's questions, Simone would most probably think .A. they are very good questionsB. Erik was an excellent listenerC. it was hard to answer the questionsD. his questions were meaningless15. The passage is written to help those who want to be .A. a good listenerB. a financial plannerC. an excellent lecturerD. a successful employee第二节(共5分:每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

豫南九校2017-2018学年下期第二次联考高二数学(文)试题第Ⅰ卷(共60分)一、选择题:本大题共12个小题,每小题5分,共60分.在每小题给出的四个选项中,只有一项是符合题目要求的.1. 已知复数满足,则复数对应的点位于复平面内的()A. 第一象限B. 第二象限C. 第三象限D. 第四象限【答案】D【解析】由题得,所以复数z对应的点为(2,-1),所以复数z 对应的点在第四象限.故选D.2. 已知复数满足,其中是的共轭复数,,则复数的虚部为()A. B. C. D.【答案】D【解析】设复数,由题得所以复数z的虚部为故选D.3. “对数函数是非奇非偶函数,是对数函数,因此是非奇非偶函数”,以上推理()A. 结论正确B. 大前提错误C. 小前提错误D. 推理形式错误【答案】C【解析】本命题的小前提是是对数函数,但是这个小前提是错误的,因为不是对数函数,它是一个复合函数,只有形如的才是对数函数.故选C.4. 在利用反证法证明命题“是无理数”时,假设正确的是()A. 假设是有理数B. 假设是有理数C. 假设或是有理数D. 假设是有理数【答案】D【解析】由于反证法假设时,是对整个命题的否定,所以命题“是无理数”是命题“是无理数”,即假设是有理数,故选D.5. 若椭圆与直线有公共点,则该椭圆离心率的取值范围是()A. B. C. D.【答案】B【解析】联立方程得消去y化简得,由题得故该椭圆离心率的取值范围是,故选B.6. 已知,则是为纯虚数的()A. 充要条件B. 充分不必要条件C. 必要不充分条件D. 既不充分又不必要条件【答案】C【解析】先考虑充分性,当x+y=0时,不一定为纯虚数,因为x-y=0时,它是实数.所以是非充分条件.再考虑必要性,当为纯虚数时,则有x+y=0且x-y≠0,所以必要性成立.故选C.7. 在平面几何里有射影定理:设三角形的两边,是点在边上的射影,则.拓展到空间,在四面体中,平面,点是点在平面内的射影,且在内,类比平面三角形射影定理,得出正确的结论是()A. B.C. D.【答案】A【解析】由已知在平面几何中,若△ABC中,AB⊥AC,AE⊥BC,E是垂足,则AB2=BD•BC,我们可以类比这一性质,推理出:若三棱锥A﹣BCD中,AD⊥面ABC,AO⊥面BCD,O为垂足,则(S)2=S△BOC.S△BDC.△ABC点睛:类比推理在几何里面是有一般规律的. 由点类比到线,由线类比到面,由面类比到体,一步一步由低级向高级在转化.本题中,类比到空间,线段的关系就要类比到面积的关系,就是这个原理.8. 下列说法正确的是()A. 命题“若,则”的否命题是“若,则”B. 命题“,”的否定是“,”C. 函数的最小值为D. 若,则“”是“”的必要不充分条件【答案】D【解析】对于选项A,命题“若,则”的否命题是“若,则”,所以选项A错误.对于选项B,命题“,”的否定是“,”,所以选项B错误.对于选项C,不能利用基本不等式求最小值,因为取等的条件不成立. 只能这样:设所以函数在上是增函数,所以t=3时函数取最小值所以选项C错误.对于选项D,由得a>1或a<0,由于a>1或a<0是“”的必要不充分条件,所以“”是“”的必要不充分条件,所以选项D正确.故选D.9. 在中,内角,,的对边分别是,,,若,,则()A. B. C. D.【解析】由正弦定理得故选A.学_科_网...学_科_网...学_科_网...学_科_网...学_科_网...学_科_网...学_科_网...学_科_网...10. 已知函数在区间上是减函数,则实数的取值范围是()A. B. C. D.【答案】A【解析】由题得在区间上恒成立,所以,设故选A.11. 已知点是抛物线上的动点,点在轴上的射影是,点,则的最小值是()A. B. C. D.【答案】B【解析】过点M作抛物线准线的垂线,垂直为N,则=-1=|PA|+|PF|-1,当A,P,F三点共线时,|PA|+|PF|最小=|AF|=所以的最小值是.故选B. 点睛:在圆锥曲线里面,我们只要看到焦半径就要联想到圆锥曲线的定义,看是否能够利用圆锥曲线的定义解题,这是一个基本的规律.本题就是利用了这个规律解题,看到点到准线的距离马上联想到转化成点到焦点的距离.12. 已知函数的定义域为,是的导函数,且满足,则不等式的解集为()A. B. C. D.【答案】B【解析】设所以函数在上是减函数,因为,所以(x+1),故选B.点睛:本题的关键是观察和联想.一是看到要联想到商的导数,从而构造函数.二是看到联想到前面的单调性,想到在不等式的两边同时乘以(x+1). 数学里的观察和联想是一种比较重要的能力,在平时的学习中要注意培养.第Ⅱ卷(共90分)二、填空题(每题5分,满分20分,将答案填在答题纸上)13. 若,则__________.【答案】6【解析】由题得,所以故填6.14. 在平面直角坐标系中,已知的顶点和,若顶点在双曲线的右支上,则__________.【答案】【解析】∵双曲线中,a=3,b=∴c==4,∴A、C恰好是双曲线的左右焦点,焦距|AC|=8根据双曲线的定义,得||AB|﹣|CB||=2a=6,∵顶点B在双曲线的右支上,∴|AB|﹣|CB|=6,△ABC中,根据正弦定理,得故.15. 给出下列说法:①线性回归方程必过点;②相关系数越小,表明两个变量相关性越弱;③相关指数越接近,表明回归的效果越好;④在一个列联表中,由计算得的观测值,则有以上的把握认为这两个变量之间没有关系;⑤设有一个线性回归方程,则变量增加一个单位时,平均增加个单位.其中正确的说法有__________(填序号).【答案】①③【解析】对于②,应该是相关系数的绝对值越小,表明两个变量相关性越弱.所以它是错误的.对于④,应该是有以上的把握认为这两个变量之间有关系.对于⑤,应该是变量增加一个单位时,平均减少个单位.故填①③.16. 观察下列的数表:…… ……设是该数表第行第列的数,则__________.【答案】4980【解析】第一行有1个偶数,第二行有2个偶数,第三行有个偶数,所以第行有个偶数,所以前n行共有个偶数,所以前n行最后一个偶数是所以第10行最后一个是2046,第10行有512个偶数,所以2018在第498个,所以m=10,n=498,所以4980,故填4980.点睛:本题归纳主要是先要发现第n行有个偶数,再就是要计算出前n行一共有个偶数,最后确定m和n就容易了.三、解答题(本大题共6小题,共70分.解答应写出文字说明、证明过程或演算步骤.)17. 已知数列为公差不为零的等差数列,,且,,成等差数列.(1)求数列的通项公式;(2)若数列满足,求数列的前项和.【答案】(1).(2).【解析】试题分析:(1)由题意可得数列的公差为,则数列的通项公式是;(2)结合(1)中求得的通项公式裂项求和可得数列的前项和.试题解析:(1)设数列的公差为由,且,,成等差数列,得,即,得,得,解得或(舍去).所以数列的通项公式为.(2)因为,所以.点睛:使用裂项法求和时,要注意正负项相消时消去了哪些项,保留了哪些项,切不可漏写未被消去的项,未被消去的项有前后对称的特点,实质上造成正负相消是此法的根源与目的.18. 某机构为研究患肺癌是否与吸烟有关,做了一次相关调查,其中部分数据丢失,但可以确定的是调查的不吸烟的人数与吸烟的人数相同,吸烟患肺癌的人数占吸烟总人数的,不吸烟的人数中,患肺癌的人数与不患肺癌的人数之比为.(1)若吸烟不患肺癌的有人,现从患肺癌的人中用分层抽样的方法抽取人,再从这人中随机抽取人进行调查,求这人都是吸烟患肺癌的概率;(2)若研究得到在犯错误的概率不超过的前提下,认为患肺癌与吸烟有关,则吸烟的人数至少为多少?附:,其中.【答案】(1).(2)20人.【解析】试题分析:(1)第(1)问,先计算出吸烟患肺癌的有16人,吸烟不患肺癌的有4人,再利用古典概型的概率公式求出这人都是吸烟患肺癌的概率.(2)第(2)问,设吸烟的人数为,列出2×2列联表,再利用卡方公式计算求出x的范围,即得吸烟的人数至少为多少.试题解析:(1)设吸烟的人数为,依题意有,所以,吸烟的有20人,故吸烟患肺癌的有16人,吸烟不患肺癌的有4人.由题意得不吸烟的有20人,其中不吸烟患肺癌的有4人,不吸烟不患肺癌的有16人.用分层抽样的方法从患肺癌的人中抽取5人,则应从吸烟患肺癌的人中抽取4人,分别记为,从不吸烟患肺癌的人中抽取1人,记为.从这5人中随机抽取2人,所有可能的结果有共10种,其中这2人都是吸烟患肺癌的结果共有6种,所以这2人都是吸烟患肺癌的概率.(或)(2)设吸烟的人数为,由题意可得列联表如下:由表得,的观测值,由题意得,解得,因为为整数且为5的倍数,所以的最小值为20,即吸烟的人数至少有20人.19. 设命题关于的不等式,;命题关于的一元二次方程的一根大于零,另一根小于零;命题的解集.(1)若为值命题,为假命题,求实数的取值范围;(2)若是的必要不充分条件,求实数的取值范围.【答案】(1)或.(2).【解析】试题分析:(1)第(1)问,先化简命题p、q和r,再由题得,一真一假,最后求出实数a的范围.(2)第(2)问,先写出和,再根据是的必要不充分条件列出不等式,即得实数的取值范围. 试题解析:对于命题:,解得或,对于命题:只需,解得,对于命题:关于的不等式的解集为.(1)若为真命题,为假命题,则,一真一假,当真假时,解得;当假真时,解得,综上可知,实数的取值范围是或.(2)若是的必要不充分条件,则,所以,所以或或,所以解得.综上,实数的取值范围是.20. 已知圆的圆心为,,为圆上任意一点,线段的垂直平分线与线段的交点为.(1)求点的轨迹的方程;(2)若过点的直线交曲线于,两点,求的取值范围.【答案】(1).(2).【解析】试题分析:(1)第(1)问,利用定义法确定点P的轨迹是椭圆,再求椭圆的标准方程.(2)第(2)问,先求出关于直线斜率k的表达式,再求函数的取值范围.试题解析:(1)连结,由于是线段的垂直平分线,所以,所以,所以点的轨迹是以为焦点,以4为长轴长的椭圆,故其方程为.(2)①当直线的斜率不存在时,,,所以.②当直线的斜率存在时,设:,代入消去得,设,则,因为,所以因为,所以,所以,综上可知,的取值范围是.点睛:本题关键是第(2)问,首先要想到函数的思想,先求出关于直线斜率k的表达式,再求函数的取值范围.函数的思想是高中数学里的一个重要思想,大家要理解掌握并灵活运用.21. 已知函数.(1)若,求曲线在点处的切线方程;(2)若函数有两个极值点,求的取值范围.【答案】(1).(2).【解析】试题分析:(1)第(1)问,先求导,利用导数的几何意义求出切线的斜率,再求切点坐标,最后写出切线的点斜式方程.

AThe other day I was shopping at a local store and came upon a lady from India squatting on the floor looking for a certain product on the bottom shelf. She sprang up when she saw me as if to get out of my way. Apologetically she explained that she was a cashier at a nearby store and was on her lunch break, trying to get a few needed items before her time was up.I reassured her, "I am in no hurry. Go ahead and do what you need to do." While she searched for a particular brand, she said that sometimes customers were rude to her at the store and she really appreciated my kindness. I told her that I had noticed cashiers being treated rudely by some people.I also explained to her that I was a retired nurse and understood some of what she was saying first hand. Sometimes patients, families, or doctors could be very rude or mean. But I tried to understand why they were feeling that way and let it go. "The world would be a better place if we all acted kindly toward each other. Those who are rude may have bad karma coming after them eventually." I added.She nodded and was surprised, “So you know about karma?” My reply was simple. “A little bit. Karma is the same thing as doing something bad and it comes back to bite you on the butt.” She paused, looked puzzled, then broke out in a big smile and covered her mouth with her hand, laughing as she walked away.It felt so good that in a brief exchange I showed her there were kind people in the world, which might have helped her regain her faith in humanity.1. How did the lady react when she saw the author in the store?A. She apologized for her rude manners.B. She invited her to have lunch together.C. She stood up trying to make way for her.D. She kept searching for the needed product.2. Which of the following best describes the author?A. Kind and understanding.B. Courageous and warm﹣hearted.C. Responsible and humorous.D. Sympathetic and open﹣minded.3. What is the main message the author wants to convey?A. Working as a cashier is no easy job.B. Those who are rude deserve bad karma.C. Doing acts of kindness will make people feel good.D. We should treat others the way we want to be treated.『答案』1. C 2. A 3. D『解析』这是一篇记叙文。

My parents found out what I needed to learn. Sometimes I had lessons but most of the time I studied things I liked. That's how home schooling works best.My favorite hobby was playing computer games. So, with Dad's help, I began to write my own computer programs. But I didn't sit at the computer all day. I liked making models tooand for that I needed …math! At school math was boring but now it was useful for m aking my models. I made a model plane and a model boat and I needed to understand science andmath to do that.So were there any bad things about home schooling? Not really. I missed my friends, but I saw them on weekends and we talked about school! They told me about their week at school and I told them about mine. Mine always sounded more fun. Some weeks I studied more than they did. Other weeks I didn't study much at all. And I never had homework!I'm 15 now and I'm back at school because I need to take exams. I don't mind.

While some people have tried going cold turkey(快速戒掉坏习惯) or even punishing themselves for their mobile phones, an app is made available in the UK that rewards people for staying away from their devices.The app, called Hold, was created by Norwegians Maths Mathisen, Florian Winder, and Vinoth Vinaya while they are studying at Copenhagen's Business school, to help break fellow students' attachments to their devices.The three college students found that positive reinforcement(强化)was the best way of beating smartphone addiction. Hold allows students to collect points for staying off their devices between the hours of 7 am and 11 pm; they get 10 points for every 20 minutes.Through partnerships with universities and businesses, points can be used for discounts on everything fromcinema tickets to Amazon goods to cafe food and drink. A half price cinema ticket, for example, costs 60 points, or 2 hours away from a phone. And a£5($ 6.88)Amazon voucher (代金券) needs 1,000 points, or 33 hours off your smartphone.Students can also use their points to buy school books and stationery(文具), which are then donated to schools partnered with children's charity Unicef.Over 120, 000 people use the app in Scandinavia, including 40 percent of higher education students in Norway, where Hold first came onto market in February 2016. It's now available to students from over 170 universities in the UK.A 2017 University of Texas study claimed that merely placing a smartphone in someone's line of sight slowed down their productivity, response time, and reduced their grades. An earlier study from the London School of Economics found students who didn't use smartphones on school grounds saw their test scores increase 6. 4 percent.24. The app Hold was created mainly to .A. promote online sales of goodsB. earn discounts on goods or servicesC. find new uses of mobile phonesD. help students put down their smartphones25. How long should a student stay off the mobile phone to get 300 points?A. 6 hours.B. 10 hours.C. 15 hours.D. 30 hours.26. What is the main purpose of the text?A. To tell the story of Hold creationB.

A computer textbookC. A science magazineD. An official documentCThe dancer put a cardigan sweater over her leotard. Then she sat down to eat a sandwich. Cardigan, leotard, sandwich-where did these words come from? Did you know that each of them was a person's name? Words that come from proper names are called eponyms(名祖名词), and there are many eponyms in English.The sandwich, for example, was named for John Montagu, the Earl(伯爵)of Sandwich. He lived from 1718-1792. He loved to play cards and did not want to stop a game even to eat. By putting cold meat between two pieces of bread, he could eat while he played.The cardigan sweater was named for an officer in the British army. In the 1800s, James Thomas Brudenell, the Earl of Cardigan, spent his own money to buy special knitted(针织的)jackets for the men in his army. Knitted jackets with buttons soon came to be called cardigans.Jules Leotard was a French circus performer. In 1859, at the age of twenty-one, Leotard performed the first mid-air somersault(空翻). He became known as the "daring young man on the flying trapeze(吊杠)". Leotard invented a close-fitting one-piece suit to wear when he performed. Dancers still call their close-fitting garments leotards.Another person who gave her name to a style of clothing was Amelia Bloomer. Bloomer was the editor of a magazine called The Lily. American women in her day were expected to wear heavy skirts that dragged on the floor. In 1851, a young woman named Elizabeth Smith Miller introduced a new kind of clothing that was much easier to move around in. She wore a dress that came only to the knees. Under it she wore loose pants that fitted close at the ankles. Amelia Bloomer published a picture of the outfit(全套服装)in the Lily. She hoped women would adopt the new style. In news stories, reporters called the pants "bloomers". A hundred years later, people were still using the word.There are many other words that come from people's names. The diesel engine was named for its inventor, Rudolf Diesel. The word boycott comes from the name of an English landlord named Charles Boycott. Where each word came from is a story in itself. Who knows, maybe your name will become a word someday.28. Why did the Earl of Sandwich invent the "sandwich"?A. He found it boring to play cards.B. He preferred to eat meat and bread.C. He wanted to create a new kind of food.D. He could eat while playing cards without stopping the game.29. According to the text, what do "bloomers" refer to?A. Loose dressesB. Loose pants worn under a dressC. Dresses that came to the kneesD. Heavy skirts dragged on the floor30. What do the words cardigan, leotard and sandwich have in common?A. They are still in use today.B. They were first used in the army.C. They belong to the clothing category.D. They were invented during the same period.31. What is the best title for this passage?A. Ways to remember words.B. Words that come from people's names.C. The history of garments development.D. The unknown stories behind English words.DA team of researchers led by engineers from Penn State University has created the first material that heals itself in the presence of water, according to a study published in Scientific Reports. The material, inspired by squid(鱿鱼)teeth, could be used to repair instruments in water-filled environments that are difficult to access, such as the human body, or the bottom of the sea.The researchers had been studying squids' ring teeth, which are uniquely strong and can change state from liquid to solid in the presence of water. After testing ring teeth samples from several species of squid found all over the world, the researchers uncovered the genetic code for the proteins (蛋白质) that allow the teeth to heal themselves when broken. They then changed the genetic structure of bacteria to produce the proteins so they could conduct more tests.The researchers then made the proteins into a rubbery plastic by mixing them with a solvent(溶剂)and letting the solvent change into a gas. The resulting material combines a soft, shapeless part of the protein that gives the plastic its self-healing characteristics and a more structured sheet of amino acids(氨基酸)that give it a solid structure.To test the material's strength, the researchers cut it, and then put the two pieces back together with a drop of water. They found that the material healed best at 113 degrees Fahrenheit, a little warmer than the temperature of the human body, and with slight pressure from a metal tool. The material was just as strong, and able to hold the same amount of weight, before and after it was cut.Material that heals itself in the presence of water could expand the usability of biomedical implants(移植). Of course, this material is nowhere near ready for that application, and the researchers didn't test whether the constant presence of water degrades(降低)the plastic's ability to heal itself. The researchers next plan to study how their technology could help heal wounds.32. According to paragraph 3, the rubbery plastic become self-healing in combination with .A. amino acidsB. another kind of rubberC. a mixture of gasesD. some protein33. In paragraph 4, the researchers carried out a test to check whether the material .A. was fit for human bodyB. would melt at high temperaturesC. could be connected with the metalD. would recover its original strength after healing itself34. What is the author's attitude towards the self-healing material?A. Positive.B. Objective.C. Doubtful.D. Critical.35. What is the main idea of the text?A. A kind of self-healing teeth was made from squids' ring teeth.B. The genetic code of squids' special teeth has been uncovered.C. Super-strong material inspired by squid teeth is self-healing.D. A special rubbery plastic is used to replace squids' teeth.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
