32、an that affects the worlds weather, may be forming again.A satellite (卫星) orbiting 600 miles above the Pacific Ocean picked up a streak (条, 带) of warm water forming along the equator (赤道) an early sign of the phenomenon felt around the world when it last appeared, just four years ago.It is more than

33、 3,000 miles long. The water in it is nine degrees warmer than in surrounding areas a substantial (相当大的) number to oceanographers (海洋学家), the warm pool is growing and has caused government forecasters to put out an advisory (气象报告).“Its a heads-up in advance so that people can properly be prepared fo

34、r this event.” Said Vernon Kousky of the National Oceanic and Atmospheric Administrations Climate Prediction Center.If a full-blown El Nino does form, Americans would most likely start to feel its effects next fall and winter.The government called the forecast very preliminary (初步的) but the warning

35、allows emergency agencies to make plans.“Right now, we cant predict whether it will be weak, moderate (中等的) or strong in intensity (强度),” said Kousky.Some Scientists say its too early to predict anything at all. “Id be very careful,” said one who asked not to be named. “There is indeed a very large

36、anomaly (反常状态) in the Pacific right now, and we need to watch it. But these things are very difficult to forecast.”El Ninos can be both good and bad, depending on where you are. Even a relatively small one can bring about significant changes by shifting the wind patterns from the Pacific Ocean that

37、pass over the United States.During the last El Nino, in 1997 and 1998, rainfall doubled in California, causing a $ 1 billion in storm damage.

42、phereUnless its raining or the wind is blowing, we dont usually pay much attention to the atmosphere, the blanket of ai that surrounds the Earth. Yet, without the atmosphere, the Earth would be a desolate (荒芜的) planet with no sign of life!The atmosphere plays several roles in helping to make life po

43、ssible. First, the atmosphere provides the three gases necessary for life: oxygen (氧气), nitrogen (氮气), and carbon dioxide (二氧化碳). All animals, including ourselves, breathe oxygen. Nitrogen and carbon dioxide are both needed for plant growth. Less important atmospheric gases include argon (氩), neon (

44、氖), helium (氦), and hydrogen (氢).Second, the atmosphere also protects us from most of the suns high-energy ultraviolet light rays (紫外线), which are harmful to life. Although these rays are only a small part of the sunlight striking the Earth, they are known to be very dangerous. However, 99 percent o

45、f all ultraviolet rays are absorbed before they reach the Earths surface. They are absorbed by an atmospheric gas, called ozone (臭氧), a type of oxygen gas. The ozone layer surrounds the Earth but is much thinner over the North and South Poles than over other regions of the Earth.The one percent of t

46、he ultraviolet light in the atmosphere that does reach the Earths surface is known to cause sunburn and is now believed to also cause skin cancer in many people. Because of this, doctors recommend that people limit the amount of time the spend in direct sunlight and wear a suntan lotion (防晒油) that b

47、locks the ultraviolet rays when they do sunbathe.Finally, the atmosphere generates all types of weather such as clear blue skies and storms. It acts as a huge energy machine, changing sunlight into other forms of energy such as heat and wind. As part of this role, the atmosphere regulates the temper

48、ature at the Earths surface. First it allows only 46 percent of the sunlight striking it to pass through and actually reach the Earths surface. Second, carbon dioxide gas in the atmosphere controls the amount of warmth on the Earths surface that it allowed to radiate (发散) back into space. By these t

49、wo controlling devices, the atmosphere regulates the Earths surface temperature.注意：此部分试题请在答题卡2上作答。46. Which of the following is true according to the passage? A) The ozone layer is much thicker over North America than over the North Pole. B) Ozone is a type of nitrogen gas. C) Ozone can absorb some

50、ultraviolet rays before they reach the Earths surface.D) Ozone can protect us from anything harmful to our life.47. The main idea of the third passage is that _.A) the Earth is surrounded by a layer of ozone B) 99 percent of all ultraviolet light rays that reach the Earths surface are absorbed by th

51、e ozone layerC) the ozone layer protects people from the suns high-energy ultraviolet light raysD) ozone is an atmosphere gas which surrounds the earth 48. According to the article, carbon dioxide _. A) is a less important atmospheric gas B) controls the amount of warmth on the Earths surface C) all

52、ow only 46 percent of sunlight to reach the Earths surface D) acts like a huge energy machine49. Doctor suggest that _. A) People should stay away from the sunlight to protect themselves form sunburnB) people should block the ultraviolet rays when they do sunbatheC) people should wear suntan lotion

53、under direct sunlightD) people should know that skin cancer results from sunbathing50. The Earth would be a desolate planet without the atmosphere because _. A) the atmosphere is mainly composed of oxygen, hydrogen and nitrogen, which are indispensable to our life B) The atmosphere plays several rol

54、es in making life possible C) the atmosphere allow only harmless rays to reach the Earth D) the atmosphere controls the amount of warmth on the Earths surfacePart VCloze(15 minutes)Directions:There are 20 blanks in the following passage.
