东北三省三校2014年高三第二次联合模拟考试(哈师大附中、东北师大附中、辽宁实验中学)英语试题第二部分:阅读理解(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的四个选项中(A、B、C和D),选出最佳选项,并在答题卡上将该项涂黑。
AI’ve often wondered if I might do more good as a travel agent rather than as a psychologist. It seems that I have been more dramatically affected by certain kinds of travel experiences than I ever have.My trip to Iceland is a fine example of that. The plan was to spend two days in a remote mountain hut in Iceland. I was working on a photographic book about winter in Iceland and needed to capture images of this amazing region of high mountain peaks, smoky volcanoes, and lakes with floating icebergs.The moment after we arrived, the weather turned extreme making visibility impossible. It snowed so much and the wind bl ew so hard that we couldn’t leave the tiny hut. To stay warm, we walked around in circles much of the day inside the tiny hut. We tried to call for help but the radio did not work. Day after day, we watched our supplies of food and fuel grow dangerously short. We got acute cabin fever (幽居病) and started going for walks and ski expeditions outside. Even when the weather finally broke, nobody came to get us even though it was three days beyond our scheduled pickup. By the time the rescue team came to pull us out, we had all given up hope.From then on, the world looks different to me, as does my life. It would have taken me years of psychotherapy to get to the same point.Almost everyone has a story to tell, and interestingly, most of these experiences were not altogether pleasant at the time. In fact, it appears that the most constructive life-changing journeys were those that involved some sorts of awful and uncomfortable events that forced the person to develop new resources, increase confidence, and solve problems in new ways.21. The writer went to Iceland to ______.A. enjoy the natural beautiful floating icebergsB. take photos about the region for a bookC. collect materials for psychological researchD. challenge the high mountains there22. During the trip in Iceland, those travelers faced difficulties EXCEPT that ______.A. they got lost in the mountainB. they were short of food and fuelC. they couldn’t see the surroundings clearlyD. they failed to get in touch with the rescue team23. From Paragraph 3, we learn that the travelers ______.A. were in despair before they were rescuedB. stayed in the hut for three days altogetherC. got sick because of going for ski outsideD. got rescued immediately the weather turned fine24. Which of the following statements is true according to the passage?A. The writer is a travel agent who loves difficult challenges.B. In Iceland the weather is always extreme and it snows a lot.C. The travellers were so depressed that they needed psychotherapy.D. Awful journeys may become life-changing events that inspire people.BOne of India’s top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students’ performance, making them lonely and even suicidal.Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. “Now, a student doesn’t even know who lives two doors away from him because he is so busy on the Internet,” said Prakash Gopalan, dean of Student Affairs. “The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion.”IIT-Mumbai, with about 5,000 students, is one of the seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional lifestyles are known to be common among IIT students, and at least nine have committed suicide inthe past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming.“Starting Monday, Internet access will be banned between 11 p.m. and 12:30 p.m. at IITMumbai’s 13 boarding buildings to encourage students to sl eep early and to try and force them out of their shells.” Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. “Now they will say we need to listen to a lullaby (摇篮曲) to go to sleep.” said Rajiv, an electronics student.25. According to the text, the students addicted to the Internet in IIT-Mumbai are likely to ______.A. perform well in studiesB. participate in social activitiesC. know their classmates betterD. feel lonely and even suicidal26. The underlined word “dysfunctional” in Paragraph 3 most probably means “______”.A. unpopularB. meaningfulC. abnormalD. exciting27. What measures have been taken in IIT-Mumbai?A. Students must go to bed before 11 p.m.B. Students are forbidden to surf the Internet on campus.C. Students have unlimited free Internet access in their dormitories.D. Internet access is unavailable in deep night in boarding buildings.28. We may infer from the last paragraph that ______.A. all electronics students hate the banning orderB. some students complain about the banning orderC. there is no Internet access on the IIT campus ever sinceD. more students prefer listening to music to surfing the InternetCWell, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It’s awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.It may sound risky, so many teens stay wi thin their own social circles to find rides, and don’t branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.“I think the digital connection of y oung people is really key, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they’ve been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn’t the car any more because there’s technology out there connecting you to a car.”According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver’s license compared to six in ten today. So it’s not that surprisin g that on my 16th birthday I wasn’t rushing to get a license but an iPhone.“Driving, for young people, does mean they have to disconnect from their technology, and that’s a negative. So if they could sit in the passage side and still be connected, that’s going to be a plus.” Schor continued.To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.29. The American teens like me, prefer to possess an iPhone as a birthday gift because _______.A. it is most fashionable and coolB. they are bored with driving carsC. they are fond of being connectedD. it is much cheaper than a car30. We can learn from the text that _______.A. Twitter is a website for teens to make friends and achieve goalsB. ridesharing can be seen as a sign that people still count on each otherC. driving cars for teens means a plus and connecting with technologyD. having a car and cost-sharing symbolize more fre edom for the author’s mother31. Professor Juliet would agree that _______.A. young people will sit waiting to be contacted by reading a passageB. sharing economy is bound to be responsible for the recessionC. young people tend to share a car with strangers by means of TwitterD. being connected via technology comes first for young people32. The best title for the passage is probably _______.A. Twitter, an Awesome WebsiteB. Cars or iPhoneC. Teens Use Twitter to Thumb RidesD. Cool Teens on the GoDNews that Microsoft made a $44.6 billion bid to buy Yahoo resulted in heated discussions made by many Internet users. Here are some responses:Diane Burke of Weeks bury, KentuckyI think it would definitely be an interesting combination. Everyone recognizes the names Yahoo and Microsoft, but everyone also says, “Did you Google it?” Such a catchphrase (时髦话) is going to be hard to beat. Shaun Carney of Laurelville, OhioI think the merger (合并) will provide more competitions for Google. I don’t think the merger will allow Microsoft to develop faster than Google, though. I believe the increased competition this merger brings will force Google to stay on top of its game by offering more fresh and original Internet tools and expanding on the tools it already offers.Toni Suarez of Hacienda Heights, CaliforniaI view the merger as a necessary element in preventing a monopolization (垄断). Perhaps it would bring better high technology innovations to e-mail and help in researching and developing a better Internet!Rick R. of Edgewater, FloridaIt sounds like a disaster to me. If this were to happen, I would stop using my Yahoo e-mail account because I don’t like the feeling of Microsoft spying upon my business. I will sign up for Google.Antonio Glosser of Kansas City, MissouriRight now, Yahoo offers a lot of features and tools at no cost for all different levels of Internet users. Micr osoft seeks nothing but profit. Undoubtedly, they’ll do nothing other than find ways to start removing Yahoo’s formerly non-priced features. Microsoft’s greed will ruin the great thing that Yahoo currently is.33. How many companies are mentioned in the passage?A. One.B. Two.C. Three.D. Four.34. Which of the following statements is NOT true according to the passage?A. Shaun’s attitude towards Google is passive.B. Toni believes the Internet will have a promising future.C. Rick will support Google after the merger.D. Antonio is afraid that the merger will cost Yahoo’s free features.35. The passage is mainly about ______.A. opinions on the merger of Yahoo and MicrosoftB. the strengths of Yahoo and MicrosoftC. the strengths and weaknesses of large companiesD. the future of Yahoo and Microsoft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。

AWoman Uses Daughter's Key to "Steal" CarCharlie Vansant, a college student of Athens, Ohio who reported that his car was stolen, got a surprise when he learned a woman had mistaken it for her daughter's car and taken it-using her key.Kate Anderson became an accidental car thief when picking up her daughter's car near an Ohio University building last week.Anderson spotted the nickel-~ay Toyota Camry(银灰色丰田凯美瑞)and used her daughter's key to unlock the car, start the engine and drive home-without realizing that the car wasn't her daughter's.When Charlie Vansant left class a short time later, he found only an empty parking spot.He first assumed the car had been towed, but when the police couldn't find a record of it, they took a theft report.The morning after Anderson took the car, her daughter discovered the Camry in the driveway wasn't hers.Anderson said she was able to find Vansant's name on paperwork in the glove compartment and look up his phone number on the website for the university.When Anderson told Charlie the car was in her driveway, "It sounded real suspicious at first, like may he she wanted to hold the thing for ransom(赎金),”said Vansant.He eventually went to the house with a police officer, where he was reunited with his car.According to police report, the ease was closed "because of mistaken car identity", Anderson wasn't charged.V ansant seemed to blame the car company more than the "thief"."Her key fit not only my lock, but my ignition(点火装置)as well - so high-five for Toyota.I guess." he said.21.What does the underlined word "towed" mean in paragraph 3?A.removed B.damaged C.stolen D.sold 22.Which of the following is NOT true according to the passage?A.Mrs.Anderson's daughter discovered the car her mother drove was not hers.B.Mrs.Anderson stole Charlie's car at the request of her daughter.C.Charlie had thought he had to give Anderson money to get his car back.D.Mrs.Anderson used her daughter's key to unlock Charlie's car and drive home.23.What does Charlie mean by "h~-five for Toyota"?A.He is blaming Toyota for the poor quality of car keys.B.He should thank Toyota for returning his car.C.He wants to celebrate with Toyota for getting his car back.D.He thinks highly of Toyota for producing large quantities of cars.24.What is likely to happen next according to the passage?A.Mrs.Anderson was charged with stealing a car.B.Charlie blamed Mrs.Anderson for mistakenly taking his car.C.Charlie would ask the Toyota Company to give him an explanation.D.The Toyota Company would give Charlie a new car as compensation.BPicture the scene: the battery on your mobile phone has run out.You can't make any calls for help and no one can contact you.You are all alone - well, not quite.Just reach into your pocket and take out a piece of sugar.Put it into the battery, wait a minute, and you're back on the phone.Thanks to a couple of American scientists, this situation could become real.Swadesh Chaudhuri and Derek Lovely have invented the "bacteria battery" - powered by bacteria that eats sugar and turns it into electricity."This is a special organism," Lovely said."You ean harvest enough electricity to power a cell phone battery for about four days from a spoonful of sugar."In the past, bacteria batteries have been expensive and not long-lasting.But this battery uses more efficient bacteria that can turn 80 percent of sugar into electrical energy.This is 30 percent more than similar batteries can manage.The bacteria battery could become as small as a household battery.It's also cheap and stable, as sugar can be taken from waste and crops.But the sugar to electricity process is slow: it could take weeks for the bacteria to digest a cup of sugar.And it produces "greenhouse" gases which pollute the environment.The scientists understand there is a lot more work to be done."It is still young," said Lovely."Where we are now is where solar power was 20 0r 30 years ago."But he believes the battery could be used in scientific equipment at the bottom of the ocean.Other ideas include using sugar in the blood to run medical devices in the human body, and taking sugar from animal waste to provide energy to power homes in rural areas.25.This passage is mainly about_ .A.how to change sugar into electricityB.a scientific invention of a new kind of bacteria batteryC.a new way to reduce pollution caused by mobile phonesD.a new kind of mobile phones and its future26.Which of the following is not the strong point of the newly-developed battery?A.Convenient.B.Stable.C.Inexpensive.D.Quick.27.The underlined sentence in the 7th paragraph actually means .A.the bacteria battery shares some similarities with solar energyB.scientists will continue their work until they find solar powerC.there is much room for the improvement of the bacteria batteryD.the bacteria battery will get popular in 20 0r 30 years28.According to the passage, who will find the bacteria battery less useful?A.Farmers.B.Divers.C.Doctors.D.Electricians.CFederal Child Labor Standards for TeenagersTeenage labor in the United StatesFederal Law sets child labor

with his injuries himself.C.Contact a supervisor when feeling uncomfortable.D.Use any tool in hand.DIt is a wonderful morning, as I write this: hot, but without being too hot.Outside my window, I can see the sunniest sky of the year reflected in a huge natural expand of water.It is the kind of sun that makes you well aware of summer's temporary nature a reminder that if I am ever to go around to book this year's holiday, time is running out.It is now close to four years since I last took a holiday.This is because I have come to the conclusion, over the course of my adult life, that I am not very good at it.You might say this sounds like saying you are not very good at drinking tea or listening to music.What could possibly be difficult about the natural act of putting your working life on hold for a couple of weeks and going somewhere to do nothing?So what is my problem? On the surface, I'm probably a bit of homebody.And I just find the pressure of being on holiday too severe: it always feels like having a gun held to my head and being forced to have fun.Somehow, packing a carefully itemized (详细列举的)list of possessions and meeting a scheduled flight has none of the excitement of suddenly deciding to take a day off and driving somewhere for the fun of it.Thankfully, I am not alone.This summer, most of my friends have decided not to have a break.And a recent survey highlighted the downside(负面)of holidays, with the results showing that nearly two thirds of people found that the calming effects of a holiday wore off within 24 hours, as stress levels returned to normal.And this year's the Idler magazine published its hook, Awful Holidays.Here you will find a list of the five most ecologically-damaging vacations it's possible to take, along with 50 horrible holidays experiences voted for on the idler website.Over the last decade, The Idler has become well known for promoting the idea of an easy, lazy life.The leisure(休闲)industry might seem an unlikely target of its criticism, but Dan Kienan, the book ' s editor, says that he was flooded with entries from readers for his list of awful holidays.32.According to the first paragraph we can know that the writer .A.has a strong desire to book a holidayB.wishes that the weather would changeC.finds it is too late to enjoy the sunshineD.realizes it's time to decide whether to go on a holiday33.The reason why the writer dislikes going on holidays is that .A.it usually costs too much moneyB.he is tired of making preparations too much for holidaysC.it is far less enjoyable than breaks planned in advanceD.he feels embarrassed when other people are having fun but he isn't34.We can learn from the survey that .A.most people pretend to enjoy their holidayB.all people fail to relax while they are on holidayC.a lot of people feel that the benefits of going on holidays are limitedD.many people have made the same decision as the writer and most of his friends 35.The writer takes the book of Awful Holidays as an example to .A.damage the reputation of the magazineB.prove the idea of living an easy, lazy life to be wrongC.indicate that his dislike of holidays is widely sharedD.focus entirely on bad personal experiences of holidays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。
