1、大学英语六级模拟试卷 228及答案与解析 一、 Part I Writing (30 minutes) 1 Directions: For this part, you are allowed 30 minutes to write a short essay entitled Computer and Online Games. You should write at least 150 words following the outline given below. 1. 大学生接触电脑 游戏的概况 2电脑游戏对大学生的利与弊 3我对这一问题的看法 Computer and Online

2、Games 二、 Part II Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-4, mark： Y (for YES) if the statement agrees with the information given in t

3、he passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Himalaya s Receding Glaciers The great majority of the worlds glaciers appear to be declining at rates equal to or greater than long-establis

4、hed trends, according to early results from a joint NASA and United States Geological Survey (USGS) project designed to provide a global assessment of glaciers. At the same time, a small minority of glaciers are advancing. Scientists monitor only a few of Indias vital glaciers, which are receding by

5、 as much as 100 feet each year. Billions of people in China and the Indian subcontinent rely on South Asias Himalayan glaciers the worlds largest store of fresh water outside the polar ice caps. The massive ice floes feed seven of the worlds greatest Asian rivers in one of the worlds most densely po

6、pulated regions. Yet as global climate change slowly melts glaciers from Africa to the Andes, scientists say the glaciers in the Himalayas are retreating air a rate of about 33 to 49 feet each yearfaster than in any other part of the world. In the Himalayas, the Gangotri Glacier, one of Indias large

7、st, is entitled to an even more dubious distinction. Recent studies reveal that the Gangotri, which forms a mass of ice about 18 miles long, is retreating at a rate of more than 100 feet a year. But according to government officials and environmental groups like Greenpeace, very little has been done

8、 in the way of a rigorous scientific study. Scientists are monitoring glacial melting on only a handful of the 7,000 glaciers that cover the Indian Himalayas. While ice reflects the suns rays, lake water absorbs and transmits heat more efficiently to the underlying ice, kicking off a feedback that c

9、reates further melting. And at such a rapid retreat, a gradual increase in droughts, flash floods, and landslides are not the only issue to worry about, say environmentalists. Glacier changes in the next 100 years could significantly affect agriculture, water supplies, hydroelectric power, transport

10、ation, mining, coastlines, and ecological habitats. Just when power companies are planning more energy sources to power Indias growing economy, a rising level of sediment in regional rivers is creating havoc for many grids. “The power grid in Uttarkashi is constantly breaking down and thats because

11、of the rise in sediment in the water being used at the hydro-power projects,“ says Joseph Thsetan Gergan from the WADIA Institute of Himalayan Glaciology, a part of the Indian Department of Science and Technology. “When the power breaks down, the people blame the Geological Survey of India or the Ce

12、ntral Water Commission for not doing its work properly, but thats like thinking of digging a well when your house is already on fire.“ While the Gangotri has been retreating since measurements began in 1842, the rate of retreat, which was around 62 feet per year between 1935 and 1971, has almost dou

13、bled. Global warming is causing Himalayan glaciers to rapidly retreat, threatening to cause water shortages for hundreds of millions of people who rely on glacier-dependent rivers in China, India and Nepal. In northwest China, the Qinghai Plateaus wetlands have seen declining lake water levels, lake

14、 shrinkage, the absence of water flow in rivers and streams and the degradation of swamp wetlands An added difficulty, says Mr. Gergan, is the lack of a sustained research effort since the 1970s. The Indian governments own recommendations, issued in March 2002 by the standing committee on Science an

15、d Technology, noted that glacial melting required immediate implementation of a program to measure and monitor the changes to the Gangotri and its impact on the Ganges river systems. “Its not enough to just note the fact that the glaciers are melting,“ Gergan says. “The impact of that is not being f

16、ocused on at all.“ Melting ice may cause serious problems and all these impacts will change with time. Indias moves in the right direction The importance of these glaciers system is because they may be melting rapidly under present climatic conditions and therefore makes large contribution to rising

17、 sea level. They are estimated to store freshwater stocks of approximately, 12 billion m3 , but have been observed to be shrinking rather fast, faster than the average global rate. In India, there are more than 5,000 glaciers on the southern slope of Himalayas covering an area of nearly 38,000 km2 .

18、 The distributions of these glaciers are higher in North-West than in the North-Eastern part of the Indian Himalayas due to the criss-cross mountains, altitude variations and different climatic environment. Glaciers are a source of continuous water supply to perennial river systems and two of the wo

19、rlds largest rivers, the Indus and Brahmaputra originate from these glacial lake systems and thereby ensure round the year irrigation facility to agriculture, which is the main string of economy of the developing nations like of India. Others say the news is not all bad for India. Suruchi Bhadwal of

20、 the Energy Resources Institute, in New Delhi says that India is the first country to have a ministry for nonconventional energy sources which has big plans for the future. “The government plans to electrify 70,000 villages using renewable energy, promote the use of biodiesel, and use low-carbon dev

21、elopment pathways,“ Mr. Bhadwal says. India has the potential to generate up to 45,000 megawatts of wind energy, but the country has only been able to harness about 2,980 megawatts as of 2004. None of these lofty goals assuages environmentalists worries, but Bhadwal is optimistic when he compares In

22、dias glaciers with those of neighboring Pakistan. “Although Indias glaciers are retreating, in Pakistan there are some that are actually growing in size,“ says R. Rangachari, a research professor at the Center for Policy Research, a New Delhi-based independent think tank. But despite such scientific

23、 ambiguities, Mr. Rangachari says Indias retreating glaciers can no longer be ignored-regardless of whether they are the fault of climate change or population increases along the higher reaches of the river. “The Gangotri has been receding for about 500 years, and there is no doubt that things are w

24、orsening, whether its climate change or anything else,“ Rangachari says. “But its no good looking at recession in isolation, or population density in isolation, the problem as a whole must be urgently attended to by the government.“ A holy place in jeopardy The Gangotri glacier terminates at a “snou

25、t,“ known to Indians as the Gaumukh, or cows head. The snout forms an ice cave and becomes the source of the Bhagirathi river. Each year, millions of pilgrims take a swim in the freezing waters here in order to free themselves from their sins. At 79, local holy man Swami Sundaranand, who lives in Ga

26、ngotri-a temple town and destination for many trekkers has been taking photos of the Gangotri glacier and the Gaumukh for more than 50 years. As a yogi, he has perfected 300 yogic positions or asanas, and climbed twice with Edmund Hillary and Tenzing Norgay. Yet it is his photographic tendencies tha

27、t have earned the Swami his nickname: “Sadhu Who Clicks,“ after the common name for an Indian ascetic. Armed with more than 100,000 photos as evidence of the glaciers shrinkage, the swami travels India holding press conferences to raise awareness of the Gangotris rapid demise. “In 1949, when I first

28、 saw the glacier, I felt as if all my sins were washed away and I had truly attained rebirth,“ the swami says. “But now, it is impossible to experience that Ganga of the past.“ 2 The passage is mainly about receding of Himalayas glaciers and its impact on the life of people. （ A） Y （ B） N （ C） NG 3
