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 convincing Other scientists to believe _____ 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】

3、Migrant (移民的) WorkersIn the past twenty years, there has been an increasing tendency for workers to move from one country to another. While some countries have restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, where increased oil incomes have enabled many countries to call in outsiders to improve local facilities. Thus the Middle East has attracted oil workers from the USA and Europe. It has brought in workers from many countries, including South Korea and Japan.In view of the difficult living and working conditions in the Middle East, it is not surprising that the pay is high to attract suitable workers. Many engineers and technicians can earn at least twice as much money in the Middle East as they can in their own country, and this is a major attraction .Sometimes a disadvantage has a compensating (补偿的) advantage. For example, the difficult living conditions often lead to increased friendship when workers have to depend on each other for safety and comfort. In a similar way, many migrant workers can save large sums of money partly because of the lack of entertainment facilities. The work is often complex and full of problems but this merely presents challenge to engineers who prefer to find solutions to problems rather than do routine work in their home country.One major problem which ______ migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. In any case, migrant workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive.【单选题】

A.invites

B.affects

C.needs

D.reflects

正确答案:B

答案解析:最后一段第一句话的大意是：影响来中东工作的工人的一个主要问题是，他们的工作是临时性的。affects（影响）符合语境。

4、Travel Across AfricaFor six hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I\'d bought in a market in Mozambique.Southern Africa was full of stories and visions. We were almost drunk on sensations. The roaring (咆哮) of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.And then the other things, dogs in the streets, whole families in Soweto livng in one room, a kilometre from clean water.As we drove towards the setting sun, a quietness fell over us. The road was empty and we hadn\'t seen another car for hours. And as I drove, something caught my eye. Something moved close enough to touch them, to smell their hot breath. I didn\'t know how long they had been there next to us.I shouted to Dan: "Look!" But he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened."Wild horses?" he said. "Why didn\'t you wake me up, Sophia?""I tried, but they were gone after a few seconds.""Are you sure you didn\'t dream it?""You were the one who was sleeping!""Typical," he said, "The best photos are the ones we never take."We checked into a dusty hotel and slept the sleep of the dead.Daniel took photos of the Nile River.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题有一定难度，需要通读全文。读完全文可以发现，文章并没有提到尼罗河the Nile of River，所以答案应该是C。

5、Indian\'s NamesEach Indian was supposed to keep his birth name until he was old enough to earn one for himself. But his playmates would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. Often it was not pleasing, such as Bow Legs or Bad Boy. But sometimes a name fit so well that the youngster found it difficult to shake it off. If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life.The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief. If he had done well, he would get a good name. Otherwise he might be called Crazy Wolf or Man-Afraid-of-a Horse. So an Indian\'s name told his record or described the kind of man he was.A man was given many chances to improve his name, however, if in a later battle he was brave in fighting against the enemy, he was given a better name. Some of our great fighters had as many as twelve names, all good and each better than the last.An Indian\'s names belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away because names were assigned by the tribe, not the family. So no man could pass on his name unless the chief and the tribe asked him to do so.Sometimes an Indian would be asked to give his name to a son who had performed a noticeable deed. I know of only three or four times when this happened. It is the rarest honor for a person -the honor of assuming his father\'s name.If an Indian had more than ten names, it meant that_____.【单选题】

A.many people in the tribe liked him.

B.he was a great fighter.

C.he had a lot of friends.

D.he had fought in fewer than ten battles.

正确答案:B

答案解析:由第3段可知印度人有很多机会改进名字，如果下一次战争中表现出色就会得到更好的名字。一些出色的斗士可能有12个名字，而且每一个都比上一个好。有10多个名字的人一定是了不起的斗士，所以选B。
