It surrounds the North Pole.Lik

9、e Antarctica, the Arctic is a land of ice and snow. Antarctica holds the record for a low temperature reading125 degrees Fahrenheit below zero. Reading of 85 degrees below zero is common in both the Arctic and Antarctica. Winter temperatures average 30 degrees below zero in the Arctic. At the South

10、Pole the winter average is about 73 degrees below zero.One thing alone makes it almost impossible for men to live in Antarctica and in parts of the Arctic. This one thing is the low temperature-the killing chill of far North and the polar South.To survive, men must wear the warmest possible clothing

11、. They must build windproof shelters. They must keep heaters going at all times. Not even for a moment can they be unprotected against the below-zero temperatures.Men have a way of providing for themselves. Polar explorers wrap themselves in warm coats and furs. The cold makes life difficult. But th

12、e explorers can stay alive.What about animals? Can they survive? Do we find plants? Do we find life in the Arctic and in Antarctica? Yes, we do. There is life in the oceans. There is life on land.Antarctica, as we have seen, is a cold place indeed. But this has not always been the case. Expedition s

13、cientists have discovered that Antarctica has not always been a frozen continent. At one time the weather in Antarctica may have much like our own. Explorers have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swamps and forests. Heat and moisture

14、 must have kept the trees in the forests alive.（分数：7.00）(1).The lowest temperature that man has ever known was recorded in Antarctica.A. Right B. Wrong C.

The ar

18、t of metallurgy includes the deriving of metals from their ores, or the condition in which they are found in nature; their purification (提纯) or their admixture with other metals, and finally their manufacture into shapes and forms usable in industry. The science of metallurgy includes the study of t

19、hese processes with a view to (以便) their control and improvement, and the development of new metal mixtures or alloys and of new test methods.2Because of this wide scope the field of metallurgy may be divided into two parts. The first part deals with the melting (熔化) and refining (精炼) of metals, and

20、 has been designated as process of Chemical Metallurgy. The second deals with the physical and chemical behavior of the metals during shaping and treating operations, and their behavior in the service of man. This phase is termed Physical Metallurgy.3The scope of Physical Metallurgy is wide and is o

21、f interest to more people than the field of Process Metallurgy. For example, only a few individuals will be engaged in the operation of a melting and refining furnace, whereas a hundred men will be employed in the rolling (轧制) or forging (锻造) of the metals produced, and thousands of individuals will

22、 work at manufacturing the rolled or forged metal into automobiles, bridges, ships, airplanes, buildings, wire goods, tools, and a multitude of useful articles.4Everyone comes in contact with metals through his many everyday uses; therefore the term metal is well known. Not everyone realizes, howeve

23、r, why metals have come to play so large a part in mans activities. Wood and stone are both older in use, yet to a considerable extent they have been substituted by the metals. The reason for the increased use of metals is to be found in their characteristic properties.5Most important of these prope

24、rties is their strength (强度), or ability to support weight without bending or breaking, combined with toughness (韧性), or the ability to bend rather than break under a sudden blow. Resistance to atmospheric destruction, plasticity (弹性) ,and the ability to be formed into desired shapes add to the rema

25、rkeable combination of properties possessed by no other class of materials. Some metals also have special additional properties, two of which are the power to conduct electric current and the ability to be magnetized.（分数：8.00）(1).Paragraph 2 _ A Division of MetallurgyB Properties of MetalC Range of

Theyre all

29、disease caused by viruses, tiny microorganisms that can pass from person to person. Its no wonder that when most people think about viruses, finding ways to steer clear of viruses is whats on peoples minds.Not everyone runs from the tiny disease carders, though. In Cambridge, Massachusetts, scientis

30、ts have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work, teaching them to build some of the worlds smallest rechargeable batteries.Viruses and batteries may seem like an unusual pair, but theyre not so strange for engineer Angela Belcher, who first cam

31、e up with the idea. At the Massachusetts Institute of Technology (MIT) in Cambridge, she and her collaborators bring together different areas of science in new ways. In the case of the virus-built batteries, the scientists combine what they know about biology, technology and production techniques.Be

32、lchers team includes Paula Hammond, who helps put together the tiny batteries, and Yet-Ming Chiang, an expert on how to store energy in the form of a battery. “Were working on things we traditionally dont associate with nature.“ says Hammond.Many batteries are already pretty small. You can hold A, C

33、 and D batteries in your hand. The coin-like batteries that power watches are often smaller than a penny. However, every year, new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink, ordinary batteries wont be small enough to fit i

34、nside.The ideal battery will store a lot of energy in a small package. Right now, Belchers model battery, a metallic disk completely built by viruses, looks like a regular watch battery. But inside, its components are very small, so tiny you can only see them with a powerful microscope.How small are

35、 these battery parts? To get some idea of the size, pluck one hair from your head. Place your hair on a piece of white paper and try to see how wide your hair is pretty thin, right? Although the width of each persons hair is a bit different, you could probably fit about lots of these virus-built bat

36、tery parts, side to side, across one hair. These micro-batteries may change the way we look at viruses.（分数：15.00）(1).According to the first paragraph, people try to_.A. kill microorganisms related to chicken pox, the flu, etc.B. keep themselves away from viruses because they are invisibleC. stay awa

37、y from viruses because they are causes of various diseasesD. cure themselves of virus-related diseases by taking medicines（分数：3.00）A.B.C.D.(2).What is Belchers team doing at present?A. It is finding ways to get rid of viruses.B. It is mass-producing micro-batteries.C. It is making batteries with vir

38、uses.D. It is analyzing virus genes.（分数：3.00）A.B.C.D.(3).What expression below is opposite in meaning to the word “shrink“ appearing in paragraph 5?A. Broaden.B. Spread.C. Extend.D. Expand.（分数：3.00）A.B.C.D.(4).Which of the following is true of Belchers battery mentioned in paragraph 6?A. It is made

39、of metal.B. It is a kind of watch battery.C. It can only be seen with a microscope.D. It is a metallic disk with viruses inside it.（分数：3.00）A.B.C.D.(5).How tiny is one battery part?A. Its width is one tenth of a hair.B. It equals the width of a hair.C. It is as thin as a piece of paper.D. Its width

40、is too tiny to measure.（分数：3.00）A.B.C.D.六、第二篇(总题数：1，分数：15.00)The SeaWhat do you know about the sea? We know that it looks very pretty when the sun is shining on it. We also know that it can be very rough when there is a strong wind. What other things do we know about it?The first thingto remember is

41、 that the sea is very big. When you look at the map of the world you will find there is more water than land. The sea covers three quarters of the world.The sea is also very deep in some places. It is not deep everywhere. Some parts of the sea are very shallow. But in some places the depth of the se

42、a is very great. There is one spot, near Japan, where the sea is nearly 11 kilometres deep! The highest mountain in the world is about 9 kilometres high. If that mountain were put into the sea at that place, there would be 2 kilometres of water above it! What a deep place!If you have swum in the sea

43、, you know that it is salty. You can taste the salt. Rivers, which flow into the sea, carry salt from the land into the sea. Some parts of the sea are more salty than other parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that swimmers cannot sink! Fish cannot live i

44、n the Dead Sea!In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are also millions of tiny living things that float in the sea. These floating things are so small that it is hard to see them. Many fish live by eating thes

45、e.The sea can be very cold. Divers, who go deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has

46、to wear clothes made of metal. But he cannot go very deep. Some people who wanted to go very deep used a very strong diving ship! They went down to the deepest part of the sea in it. They went down to a depth of eleven kilometres!（分数：15.00）(1).When does the sea look beautiful?A. When it is calm.B. W

47、hen the weather is fine.C. When there is a strong wind.D. When there is a storm.（分数：3.00）A.B.C.D.(2).How much of the earths surface does land cover?A. 15%. B. 25%. C. 30%. D. 45%. （分数：3.00）A.B.C.D.(3).Why does the author cite the sea somewhere near Japan?A. To show that the sea in some places is ver

48、y deep.B. To show that the sea in some places is very shallow.C. To show that its depth is 9 kilometres greater than the height of the highest mountain.D. To show that its depth is 11 kilometres greater than the height of the highest mountain.（分数：3.00）A.B.C.D.(4).Which of the following statements ab

49、out the Dead Sea is NOT true?A. There are plenty of fishes in it.B. It is a safe place for swimmers.C. It is extremely salty.D. No fish can be found in it.（分数：3.00）A.B.C.D.(5).Why cant people go very deep in the sea?A. Because the deepest part of the sea is very cold.B. Because the deepest part of the sea is very rough.C. Because the pressure of water at great depths is unendurable.D.
