1、Arctic MeltEarth\'s North ａｎｄ　South Poles are famous fｏｒbeing cold ａｎｄ　icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter ａｎｄ　shrinks(缩小) during the summer. But fｏｒmany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent ｄｒｅｐin end of summer ice cover. Between 1981 ａｎｄ　2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. ａｎｄ　it\'s a very large 23 percent below the previous record low, which was ｓｅｔjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons fｏｒthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice ａｎｄ　open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water ａｎｄ　the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average ａｎｄ　1.5c warmer than the previous record.With both air ａｎｄ　water getting warmer, the ice is melting from both above ａｎｄ　below. In some parts of the Beaufort Sea, north of Alaska ａｎｄ　western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.The word "builds" in paragraph 2 could be best replaced by ______【单选题】

A.establishes

B.expands

C.creates

D.constructs

正确答案:B

答案解析:本题难度不大，文章此处build的引申意义指“（冰层）加厚”，选项中expands是其近义解释，答案是B。

2、Stress Lessen CourseDoreen Sykora is now a juniｏｒat McGill University. She had a difficult time when she first began college. She said, "I was always well prepared fｏｒmy examinations. But I would go in to class to take the exam, ａｎｄ　I would fall apart. I could not answer the questions correctly-even though I knew the answers! I would just blank out because of nervousness ａｎｄ　fear". Histoshi Sakamoto, an anthropology student at Temple University in Tokyo reports similar experiences. These two young students were experiencing something called test anxiety. Because when a student worries ａｎｄ　is stressed about a test, his ｏｒher mind does not work as well as it usually does. The student cannot write ｏｒthink clearly because of the severe tension ａｎｄ　nervousness. Now there are special university courses to help students. In these courses, advisors ａｎｄ　psychologists try to help students by teaching them to manage test anxiety. Such a course helps students learn to live with stress ａｎｄ　not fail because of it. First students take a practice test to measure their worry level. If the tests show that their stress level is high, the students can take a short course to manage the fear. These courses teach students how to relax their bodies. They get training to become calm in very tense situations. By controlling their nervousness, they can let their minds work more easily. Learned information then comes out without difficulty on a test. Doreen Sykora saw immediate results after taking such a course. She now has enthusiasm about the relaxation methods. "Mostly, what I do is imagine myself in a very calm place. Then I imagine myself picking up a pencil. I move slowly ａｎｄ　carefully. I breathe easily ａｎｄ　let all the tension out. With each breath, more worry leaves me. It really works too. My grades have improved greatly! I\'m really doing well at McGill now. This relaxation method works not only on examinations, but it has improved the rest of my life as well". FｏｒHistoshi in Tokyo, the results were much the same. He is enjoying school a lot more ａｎｄ　learning more. These are signs of test anxiety EXCEPT____.【单选题】

A.worries about a test

B.stressed about a test

C.low grades ａｎｄ　poｏｒstudy habits

D.nervousness during the test

正确答案:C

答案解析:第1段讲述了两个学生的详细情况，出于对考试的担心、压力、紧张，使得他们难以考好。如果是成绩不好、学习习惯不好，即便不紧张也是考不好的。因此C是答案。

3、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 _____ 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 would 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.by

B.away

C.along

D.with

正确答案:B

答案解析:本题难度较大，考查词义辨析，干扰项干扰较大。根据上下文逻辑，文章此处是说“当我们飞离太阳时温度会变得更低”，答案是B。

4、The maximum speed of this car is 150 miles per hour. 【单选题】

A.highest

B.lowest

C.minimum

D.supreme

正确答案:A

答案解析:highest：最高的，可以修饰speed，替换maximum（最大的）；minimum:最小的；lowest：最低的；supreme：级别最高的。

5、AIDSAs a science writer, I don\'t have to wear emotional armｏｒvery often. Before I went to Zimbabwe fｏｒa visit, I had talked to other reporters who had spent time in Africa. All told me to get prepared fｏｒthe orphans, many of whom had caught the AIDS virus from their mothers ａｎｄ　the strong desire to make everything all right fｏｒthem. Then again, nothing could have prepared me fｏｒthe visit to creche(育婴堂) fｏｒAIDS orphans in Harare, where one sick, smiling four-year-old boy tried to keep up with the other kids playing ring-around-the-rosy but was so weak he kept falling to the floor, ｏｒmeeting a 25-year-old unmarried girl who cared fｏｒher nephew Only when I got back about a week later The boy who called his aunt "Mama" was too weak even to take the piece of banana I offered. Meanwhile photojournalist Karin Retief was visiting a room at the hospice (济贫院) where she had been told a particularly sweet orphan boy stayed. At first she did not see anyone on the bed ａｎｄ　was about to say he must be elsewhere, when suddenly she spotted his tiny arm in the air, his body lost in the folds of the bedclothes. Recently Karin wrote to me that she had been able to keep our assignment from taking too great an emotional suffering at the time. " ______, could I moum the people I met", she continued. "I sat in church ａｎｄ　wanted to ask the priest to pray fｏｒthe people with AIDS in Zimbabwe ａｎｄ　all over the world. Then all the people\'s faces, pain ａｎｄ　suffering became so real, I could not get the words out. I broke down ａｎｄ　cried ａｎｄ　cried fｏｒthem". 【单选题】

A.where she had been told a particularly sweet orphan boy stayed

B.who had spent time in Africa

C.Only when I got back about a week later

D.even though her only income was from growing ａｎｄ　selling a few vegetables at the local market

E.was so weak he kept falling to the floor

F.while we were visiting the orphans

正确答案:C

答案解析:句首需要大写，选项中只有C的开头是大写。另外后面的句子是倒装语序，就要考虑某些特殊的句式结构。因此选C。
