2、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 _____ 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 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.whether

B.where

C.what

D.when

正确答案:A

答案解析:本题难度不大,考查whether or的用法,答案干扰项干扰不大。可以先看选项得到信息提示。很明显,此处是whether or结构,是说“温度(的多少)取决于你是否在阳光下或阴影里”,答案是A。

3、The chairman proposed that we stop the meeting.【单选题】

A.stated

B.announced

C.demanded

D.suggested

正确答案:D

答案解析:主席建议我们中止会议。本题难度不大,考查的是基本意义,干扰项干扰不大。propose和suggest都有“建议”的意思,是近义词,A项指“陈述”,B项指“宣布”,C项指“要求”和答案意义差异大,最佳答案是D。

4、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building and that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home forblind people in Sommersetand a resource centre forthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the doorwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the ______ of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising orfalling frequencies to indicate whether people should go up ordown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】

A.feature

B.quality

C.diagram

D.source

正确答案:D

答案解析:解题关键是要看出句子中主要结构是more. . . than,后面出现核心词the source,所以可以得出结论,前面的名词也应是source,这样符合比较级用法,用来进行比较的事物必须具有可比性,所以选D。

5、Snow RangerThe two things, snow and mountains, which are needed fora ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain, often called "White Death. "It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937, 38 at Alta, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a majorski area. Thus, development of Alta and other majorski resorts in the west was dependent upon controlling the avalanche. The Forest Service setout to do it, and did with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber. He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better. He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety forpeople on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, ortalks with the ski area\'s operatoras he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes. The passage implies that a snow ranger____. 【单选题】

A.knows how to use a pistol.

B.must write lengthy reports on his work.

C.may travel many miles when he is on duty.

D.has a long working day.

正确答案:C

答案解析:A:知道怎样使用手枪;B:必须写有关其工作的长篇报告;C:值班时可能会滑行数英里;D:工作时间很长。依据常识和已有的对文章的了解推断C最合理。如果依据原文,文章中提到了“枪”的使用,所以A不是答案。在第5段中说“雪地管理员”必须身体素质好,所以暗示答案是C。
