1、Arctic MeltEarth\'s North ａｎｄ　South Poles are famous fｏｒbeing cold ａｎｄ　icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter ａｎｄ　shrinks(缩小) during the summer. But fｏｒmany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent ｄｒｅｐin end of summer ice cover. Between 1981 ａｎｄ　2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. ａｎｄ　it\'s a very large 23 percent below the previous record low, which was ｓｅｔjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons fｏｒthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice ａｎｄ　open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water ａｎｄ　the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average ａｎｄ　1.5c warmer than the previous record.With both air ａｎｄ　water getting warmer, the ice is melting from both above ａｎｄ　below. In some parts of the Beaufort Sea, north of Alaska ａｎｄ　western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.By the end of summer 2007 the ice cover in the Arctic was ______【单选题】

A.38 million square kilometers

B.4.2 million square kilometers

C.1.13 million square kilometers

D.11.4 million square kilometers

正确答案:B

答案解析:本题难度不大，答案依据比较明显，文章第四段第二句谈到了，到2007年夏季结束时，冰层缩减至仅覆盖420万平方公里，所以答案是B。

2、How to Be a Successful BusinesspersonHave you ever wondered why some people are successful in business ａｎｄ　others are not? Here\'s a story about one successful businessperson. He started out washing dishes ａｎｄ　today he owns 168 restaurants.Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, ａｎｄ　when he was 16 years old, he learned to fly a small plane.At the age of 23 ａｎｄ　with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working fｏｒa company that rented cars.While Mr. Kazi was working at the car rental(租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. Fｏｒtwo months, he worked as a cook\'s assistant. His job was to clean the kitchen ａｎｄ　help the cook. "I didn\'t like it," Mr. Kazi says, "but I always did the best I could."One day, Mr. Kazi\'s two co - workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.A few months later, the owners needed a manager fｏｒa new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager ａｎｄ　soon the restaurant was making a profit.A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside ａｎｄ　the food was terrible. Mr. Kazi borrowed money from a bank ａｎｄ　bought the restaurant. Fｏｒthe first six months, Mr. Kazi worked in the restaurant from 8 a. m. to 10 p. m. , seven days a week.

With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, ａｎｄ　retrained the employees.

5、Rockets in the SkyIf someone asked you. "What colｏｒis the sky?" I expect that you would answer, "Blue." I am afraid that you would be wrong. The sky has no color. When we see blue, we are looking at blue sunlight. The sunlight is shining on little bits of dust in the air. We know that there is air all around the world. We could not breathe without air. Airplanes could not fly without air. They need air to lift their wings. Airplanes cannot fly very high because as they go higher the air gets thinner. If we go far enough away from the earth, we find there is no air. What is the sky? The sky is space. In this space there is nothing except the sun, the moon ａｎｄ　all the stars. Scientists have always wanted to know more about the other worlds in the space. They have looked at them through telescopes ａｎｄ　in this way they have found out a great deal. The moon is about 384,000 kilometers away from the earth. An airplane cannot fly to the moon but there is a thing that can fly even when there is no air. This is rocket. I am sure that you are asking. "How does a rocket fly?" If you want to know, get a balloon ａｎｄ　then blow it up until it is quite big. Do not tie up the neck of the balloon. Let go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out. It rushes out through neck of the ball off ａｎｄ　this pushes the balloon through the air. It does not need wings like an air plane. This is how a rocket works. It is not made of rubber like a balloon, of course. It is made of metal. The metal must not be heavy but it must be very strong. There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket, the rocket is pushed up into the air. Rockets can fly far out into space. Rockets with men inside them have already reached the moon. Several rockets, without men inside them, have been sent to other worlds much farther away. One day rockets may be able to go anywhere in the space. A rocket is pushed up into the air when____. 【单选题】

A.hot gas rushes out of its head.

B.it is powered by gas.

C.hot gas rushes out of its bottom.

D.hot gas rushes out of its neck.

正确答案:C

答案解析:根据文章倒数第2段最后一句( When it rushes out of the end of the rocket)。
