1、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have _____ vials (小药瓶). and the last "official" stocks of live Virus bred mistrust of the US and Russia, forno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fortests on new treatments and vaccines(疫苗). So once again there\'s a good reason to the virus, just in keep the disease puts in a reappearance.How do we case with the mistrust of the US and Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn\'t mean the idea is rejects. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【单选题】

A.more

B.few

C.a few

D.a lot

正确答案:C

答案解析:本题有一定难度,本题可用排除法,文章里没有出现比较的含义,所以more可以排除掉,a lot后面不能接名词,不能说a lot vials,所以也可以排除掉,依据上下文逻辑,文章此处是说“毫无疑问,几个国家仍有几瓶(病毒)”,此处要用“几个”的意思,只能用a few,答案是C。

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 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。

3、It took us a long time to mend the house. 【单选题】

A.build

B.destroy

C.design

D.repair

正确答案:D

答案解析:mend和repair都有“修理”的意思;build:建设;destroy:破坏;design:设计。

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 ______ 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 source 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.run by

B.changed by

C.decorated by

D.criticized by

正确答案:A

答案解析:我们知道Sound Alert是一家公司的名字,从语意上判断应该是由某人经营,因此选择A较为合适。

5、So far no one has been able to account forthe cause of the accident. 【单选题】

A.assess

B.explain

C.describe

D.investigate

正确答案:B

答案解析:account for和explain同义,解释、说明;assess:评估;describe:描述;investigate:调查。
