1、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 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 or shade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area 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 temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble _____ Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold 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(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

A.convincing

B.begging

C.ordering

D.forcing

正确答案:A

答案解析:Bose 一筹莫展，只好求助于爱因斯坦，后者通过计算证实了Bose的理论。本题选 convincing（说服）最恰当。ordering（命令）或forcing（强迫）都不合逻辑。而begging恳求）也太低三下四了。

2、Desirable Qualities in a TeacherHere I want to try to give you an answer to the question: What personal qualities are desirable in a teacher? Probably no two people would draw up exactly similar lists, but I think the following would be generally _____.First, the teacher\'s personality should be pleasantly live and attractive. This does not rule out people who are physically plain, or even ugly, because many such have great personal charm. I would say that excludes all of dull or purely negative personality. I still stick to what I said in my earlier book: that school children probably suffer more from bores than from brutes.Secondly, it is not merely desirable but essential for a teacher to have a great capacity for sympathy in the literal meaning of that word; a capacity to tune in to the minds and feelings of other people, especially, since most teachers are school teachers, to the minds and feelings of children. Closely related with this is the capacity to be tolerant not indeed, of what is wrong, but of frailty （脆弱) and immaturity of human nature which induce people, and again especially children, to make mistakes.Thirdly, I hold it essential for a teacher to be both intellectually and morally honest. This does not mean being a plaster saint. It means that he will be aware of his intellectual strengths.【单选题】

A.accepted

B.agreed

C.approved

D.admitted

正确答案:A

答案解析:选项B和C都是不及物动词，而选项D意为“承认”，不符合文意.

3、G8 SummitLeaders of the Group of Eight Major Industrialized Nations (G8) will meet in Scotland in July this year. Representatives from China, India, Mexico, South Africa and Brazil have also been invited. Here\'s what the G8 leaders want from the meeting.British Prime Minister Tony Blair wants the G8 to cancel debt to the world\'s poorest countries. He wants them to double aid to Africa to 50 billion pounds by 2010. He has also proposed reducing subsidies to Western farmers and removing restrictions on African exports. This has not got the approval of all members because it will hurt their agricultural interests. On climate change, Blair wants concerted (共同的) action by reducing carbon emissions (排放). US President George W. Bush agrees to give help to Africa. But he says he doesn\'t like the idea of increasing aid to countries as it will increase corruption. Bush said he would not sign an agreement to cut greenhouse gas emissions at the summit, according to media. The US is the only G8 member not to have signed the Kyoto Protocol(《京都议定书》). Although the US is the world\'s biggest polluter, Bush so far refuses to believe there is sufficient scientific data to establish beyond a doubt that there is a problem.French President Jacques Chirac supports Blair on Africa and climate change. He is determined to get the US to sign the climate change deal.German Chancellor Gerhard Schroder remains doubtful of Blair\'s Africa proposals. Schroder\'s officials have dismissed the notion that money will solve Africa\'s problems as"old thinking". Berlin says that African states should only receive extra money if they can prove they\'ve solved the corruption problem.Russian President Vladimir Putin was doubtful about the value of more aid to Africa. But he has seen a way to make this work to his advantage. Putin intends to use the aid to Africa as a springboard (跳板) next year to propose aid to the former Soviet Republics of Georgia, Uzbekistan, Tajikistan and Moldova.Japanese Prime Minister Junichiro Koizumi\'s priorities are a seat on the UN Security Council, for which he will be lobbying (游说) at the summit. And he\'s concerned about the Democratic People\'s Republic of Korea\'s nuclear weapons programme.Chirac takes a stand similar to Blair’s on Africa and climate change.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:根据主语Chirac可以确定答案出自第四段。第四段第一句：French President Jacques Chirac supports Blair on Africa and climate change. （Chirac支持布莱尔对非洲和气候变化的看法及态度。）这与题干所表达的意思是一致的，故正确答案是A。

4、A Country\'s Standard of LivingThe "standard of living" of any country means the average person\'s share of the goods and services the country produces. A country\'s standard of living, therefore, depends first on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy: "goods such as food and clothing", and "services" such as transport and entertainment.A country\'s capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country\'s natural resources. Some region of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate, other regions possess none of them.Next to natural resources comes the ability to ____ them to use, China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external wars, For this and other reasons it was unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasions, enable a country to develop its natural resources peacefully and steadily, to produce more wealth than other country.A country\'s standard of living does not only depend upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain\'s wealth in foodstuffs and other agricultural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products which would otherwise be lacking. A country\'s wealth is, therefore, much influenced by its manufacturing capacity, providing that other countries can be found ready to accept its manufactures.【单选题】

A.move

B.force

C.turn

D.push

正确答案:C

答案解析:本题有一定难度，干扰项干扰较大，本题考点是动词短语turn to，使变成，最佳答案是C。

5、Stop Eating Too much"Clean your plate!"and" Be a member of the clean-plate club!" Just about every kid in the US has heard this from a parent or grandparent. Often, it\'s accompanied by an appeal: "Just think about those starving orphans (孤儿) in Africa!" Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of saying "clean the plate", perhaps we should save some food for tomorrow.According to news reports, US restaurants are partly to blame for the growing bellies(肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.Barbara Rolls, a nutrition (营养) professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline(腰围) began to expand.Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believed restaurants served portions that were too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can\'t afford fine dining still prefer large portions. Seventy percent of those earn at least $ 150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25, 000 want smaller.It\'s not that working class Americans don\'t want to eat healthy. It\'s just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck (薪金支票) to paycheck, happy to save a little money for next year\'s Christmas presents.(2008年)Which of the following is NOT true of working class Americans?【单选题】

A.They work long hours.

B.They live from paycheck to paycheck.

C.They want to save money for presents.

D.They don\'t want to be healthy eaters.

正确答案:D

答案解析:题干问“以下哪一种说法不符合美国工人的实际情况”。参见最后一段第一句话：美国工人不是不想吃得健康。而选项D正与文意相反，故正确答案为D。
