1、A Great Quake Coming?Everyone lives in San Francisco knows that earthquakes are common in the Bay Area ａｎｄ　they can devastate. In 1906, fｏｒexample, a majｏｒquake destroyed about 28000 buildings ａｎｄ　killed hundreds, perhaps thousands of people. Residents now wonder when will the next "Big One" strike. It\'s bound to happen someday. At least seven active fault(断层) lines run through the San Francisco area. Faults are places where pieces of Earth\'s crust (地壳) slide past each other. When these pieces slip, the ground shakes.To prepare fｏｒthat day, scientists are using new techniques to reanalyze the 1906 earthquake ａｎｄ　predict how bad the damage might be when the next one happens.One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture(断裂) about 2.7 kilometers persecond. During bigger quakes, however, ruptures can happen faster than 3.5 kilometers persecond.At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky fｏｒSan Francisco, these pressure pulses (脉冲) traveled away from the city during the 1906 event.Looking ahead, scientists are trying to predict when the next majｏｒquake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a majｏｒearthquake striking the Bay Area before 2032 is at least 62 percent.New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city\'s buildings are old ａｎｄ　weak. Analyses suggest that another massive earthquake would cause extensive damage.People who live there today tend to feel safe because San Francisco has remained pretty quiet fｏｒa while. According to the new research, however, it\'s not a matter that whether "the Big One" will hit here. It\'s just a matter of when.Scientists will be able to predict the exact time of an earthquake soon.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题难度较大，没有明显的答案依据，需要通读全文，做出判断。第五段第一句：Looking ahead, scientists are trying to predict when the next majｏｒquake will occur.{炎到展望未来，科学家正努力预测下次大地震的发生，但全文只谈到在积极预测地震，没有提及是否能够预测出准确的时间，所以本题未提及，答案是C。

2、The great change of the city astonished all the visitors.【单选题】

A.surprised

B.scared

C.excited

D.moved

正确答案:A

答案解析:这座城市发生的大变化使所有的参观者惊讶。本题难度不大，干扰项干扰不强。astonished和surprised都可指“吃惊的”，B项指“使惊吓”，最佳答案是A。

3、It is absurd to predict that the sun will not rise tomorrow.【单选题】

A.ridiculous

B.funny

C.odd

D.foolish

正确答案:A

答案解析:题干大意：预测明天太阳不会升起是荒谬的。画线词absurd：荒谬的，和ridiculous完全是相同的意思。odd：奇怪的。funny：滑稽可笑的。foolish：愚蠢的。故答案选A。

4、Strike in MTV NetworksScores of workers from MTV Networks walked off the job yesterday afternoon, filling the sidewalk outside the headquarters of its corporate parent, Viacom, to protest recent changes in benefits. The walkout highlighted the concerns of a category of workers who are sometimes called permalancers： permanent freelancers who work like full-time employees but do not receive the same benefits.Waving signs that read "Shame on Viacom", the workers, most of them in their 20s, demanded that MTV Networks reverse a plan to reduce health ａｎｄ　dental benefits fｏｒfreelancers beginning Jan. 1. In a statement, MTV Networks noted that its benefits program fｏｒfull-time employees had also undergone changes, ａｎｄ　it emphasized that the plan fｏｒfreelancers was still highly competitive within the industry. Many freelancers receive no corporate benefits. But some of the protesters asserted that corporations were competing to see which could provide the most mediocre health care coverage. Matthew Yonda, who works at Nickelodeon, held a sign that labeled the network "Sick-elodeon". "I\'ve worked here every day fｏｒthree years-I\'m not a freelancer," Mr. Yonda said. "They just call us freelancers in ｏｒｃｅｒto bar us from getting the same benefits as employees."The changes to the benefits package were announced last Tuesday. Freelancers were told that they would become eligible fｏｒbenefits after 160 days of work, beginning in January. While that eased previous eligibility rules, which required freelancers to work fｏｒ52 weeks before becoming eligible, it would have required all freelancers not yet eligible fｏｒbenefits to start the waiting period over again on Jan. 1. The 401 (k) plan was also removed On Thursday, acknowledging the complaints, MTV Networks reinstated the 401 (k) plan ａｎｄ　said freelancers who had worked consistently since March would be eligible.Fueled by a series of blog posts on the media web site Gawker-the first post was headlined "The Viacom Permalance Slave System" -a loose cohort of freelancers created protest stickers ａｎｄ　distributed walkout fliers last week. Caroline O\'Hare, a unit manager who has worked fｏｒMTV fｏｒmore than two years, said the new health care plan-with higher deductibles ａｎｄ　a $ 2,000 cap on hospital expenses each year-had provoked outrage. "They think they can treat us like children that don\'t have families, mortgages ｏｒdreams of retirement," she said.Outside Viacom\'s headquarters, several workers held posters with the words, "There\'s too many of us to ignore." It was unclear how many freelancers are on the company\'s payroll； an MTV Networks spokeswoman said the figure was not known because it rises ａｎｄ　falls throughout the year. The company has 5,500 full-time employees, excluding freelancers, around the world.Two freelancers ａｎｄ　one full-time employee, who asked not to be identified fｏｒfear of retribution, estimated that the percentage of freelancers in some departments exceeded 75 percent. Another labｏｒaction is expected to take place outside Viacom later this week. Members of the Writers Guild of America, who have been on strike fｏｒfive weeks, are expected to picket there on Thursday.Which one of the following statements is NOT true of MTV Networks\' new benefits plan fｏｒfreelancers?【单选题】

A.Its benefits plan fｏｒfreelancers is highly competitive in the industry.

B.Its freelancers cannot receive the same benefits as the full-time employees.

C.The freelancers who are not eligible fｏｒbenefits should start the waiting period over again on Jan. 1.

D.The freelancers are against the new plan which substantially but their benefit.

正确答案:C

答案解析:细节考查题。题干考查的是与新福利方案不符的一项。只有选项C符合题意，故正确答案为C。

5、A special educationVideodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, ｏｒsocializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one ｏｒmore of the following ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, ｏｒother health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, ａｎｄ　indefatigable (孜孜不倦) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, ａｎｄ　designers can assure absolute consistency within a program. Most important, according to special educatｏｒWilliam Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism fｏｒchildren who need graphic representations."Healey explained that deaf ａｎｄ　mentally retarded children especially have difficulty grasping figurative language ａｎｄ　higher-ｏｒｃｅｒlanguage concepts. He believes that fｏｒspecial education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken fｏｒgranted by non-handicapped persons. Complex figurative language forms such as idioms ａｎｄ　metaphors come most readily to mind as being difficult fｏｒhandicapped learners. A videodisc courseware is beneficial to those who have study difficulties because______【单选题】

A.its fancy design is very attractive

B.it allows the user to go back to where he wants to restudy

C.the content of it is healthy ａｎｄ　promising

D.it is developed by university professors

正确答案:B

7、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms _____ behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.would

B.will

C.must

D.need

正确答案:A

答案解析:本题有一定难度，考查虚拟语气和时态一致的用法，干扰项有一定的干扰。根据上下文逻辑，文章此处是说“爱因斯坦的计算帮助Bose理论成立，即原子会象原来他设想的那样运行”，此处只是表示理论成立，而不等于是经过验证的科学事实，所以要用假设的语气，此外整个句子都是用的过去时态，因此答案是A。

8、Walking to Exercise the BrainDo you think sitting ａｎｄ　studying all the time will improve students grades? Think again. Getting some exercise may help, too.New research with older people suggests that taking regular walks helps them pay attention better than if they didn\'t exercise.Previous research had shown that mice learn, remember ａｎｄ　pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don\'t. Their brain cells also make more connections.Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true fｏｒpeople. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen ａｎｄ　had to use computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task, ａｎｄ　their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible fｏｒpaying attention ａｎｄ　making decisions.In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching ａｎｄ　toning (韵律操) exercises fｏｒthe same amount of time.So, even going fｏｒa walk every 2 ｏｒ3 days fｏｒjust 10 to 45 minutes can help. That should be good news fｏｒthe elderly.The effects of exercising on the brains of younger people haven\'t been studied yet. Still, it can\'t hurt to take occasional breaks ａｎｄ　go fｏｒa walk ｏｒrun around with friends. Whatever you do, though, don\'t try to read ａｎｄ　walk at the same time. You could end up hurting yourself!It can be good fｏｒhealth when one takes a walk every 2 ｏｒ3 days fｏｒat least ______.【单选题】

A.3 minutes

B.45 minutes

C.30 minutes

D.10 minutes

正确答案:D

答案解析:本题有一定难度，需要认真阅读文章。答案依据在文章第七段。带着题干信息词回到文章定位。第七段第一句谈到，每两三天出去散步10到45分钟会对健康有益，回来看选项，很明显，D是近义解释，是答案。
