You should write at 120 words according to outline given below in Chinese:1.计算机游戏对大学生有一定一处;2.但是现在有太多的人沉迷其中;3.你的看法.Computer Games on CampusToday, many college students are absorbed in playing computer games. I understand that computer games are fun, but they may do more harm than good to you.First, it is very time-consuming to play computer games. If you spend too much time on them, you will have no time to attend classes, to take exercises, or even to date. Upon graduation many will regret that they have wasted the precious college time on nothing. Second, those who play computer games excessively would easily fall victim to various illnesses. For example, game fans always fix their eyes on the screen, therefore they are likely to be near-sighted. Third, the games fans, who spend their time before the lifeless computers, usually overlook their relationship with others.Computer games are fun, but do not spend too much time on them. There are simply a lot of more important things in life.Part Reading Comprehension (Skimming and Scanning) (15 minutes)Global Water ProblemThe UN's World Summit on Sustainable Development to be held in Johannesburg from August 26 to September 4 is supposed to result in plans to reduce global poverty and the North-South income gap without causing irreparable damage to the environment. As a follow-up to the Earth Summit of 1992, it is using the Millennium Development Goals (MDG) as a guide. These are part of the UN's2000 Millennium Declaration, which resolved to cut the proportion of people who are unable to get safe drinking water in half by 2015.Following are some facts and figures on the state of the world's water supplies and the UN's goals regarding water.Water Supply and ShortageA new study warns that about thirty per cent of the world's people may not have enough water by the year 2025. A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries which are mostly in Africa or the Middle East.PAI researcher Robert Engelman says by the year 2025, about three billion people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.Freshwater ecosystems cover less than 1 per cent of the Earth's surface. Ice-mostly in the form of glacier-comprises 69 per cent of the world's freshwater supplies and groundwater is 30 per cent. Wetlands, which include marshes and swamps, comprise 0.3 per cent, lakes 0.3 per cent, and rivers 0.06 per cent. However, many experts argue that the world's wells are not about to run dry.They say that on a global level we have enough water but must use it more wisely and attempt to address uneven distribution around the globe which is related partly to different rainfall patterns.Problem/issueLack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking water is not safe. Mr. Engelman says there are problems all over the world because of diseases such as cholera which are carried in water. Lack of water may also result in more international conflicts. Countries may have to compete for water in the future. Some countries now get sixty per cent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. Water shortage would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.Moreover, there are many problems with the world's fresh water supplies, including pollution from industry, agriculture and untreated sewage. The World Bank says inefficient infrastructure means that water that does not reach customers is not only wasted but ultimately not paid for. This can lead to infrastructure decay because of a lack of funding for maintenance. Tariffs are often kept low by politicians seeking to woo voters, leading many to advocate the privatization of water services-95 per cent of municipal water services are publicly run-but this is controversial because of concerns that the very poor could be denied access. Privatization advocates argue that services will improve at a lower cost as a result because the contracted operators will have an incentive to improve their product.DamsDams have brought huge benefits to more than 140 countries but the social and environmental costs have often been high. Perhaps 40 to 80 million people have been displaced globally by dam projects. Dams have damaged aquatic habitats and blocked migration routes. According to a 2000 report by the World Commission on Dams, China and India have half of the world's 45,000 dams. Dams account for only 19 per cent of electricity generated worldwide, but 24 countries generate more than 90 per cent of their power from dams.Species at RiskAccording to the WWF (World Wildlife Fund), of 10,000 species of freshwater fish, 20 per cent are threatened by pollution, habitat destruction, damming, over-fishing and the introduction or invasion of alien species. The WWF says that 81 freshwater fish species have become extinct over the past century. The major proportion of known extinctions resulted from the huge Nile perch in Africa's Lake Victoria, which caused the loss of 50 species. But scientists say the state of knowledge about freshwater fish is incomplete so many unknown to us may have become extinct already.In addition to fish, the WWF says that four of the five species of river dolphins, two of the three manatee species, about 40 freshwater turtles and more than 400 types of freshwater crustaceans are at risk.An Example of MisuseThe land-locked Aral Sea, which straddles the former Soviet Central Asian republics of Uzbekistan and Kazakhstan, is actually salty, but its tragedy highlights the potentially disastrous consequences of poor freshwater use. In the 1960s, Soviet planners built a network of canal to divert the waters of the river that river that fed the sea to irrigate cotton fields in Uzbekistan and Turkmenistan. As a result, the sea's life source was reduced to a trickle, and it is shrinking and dying as a result. Once the world's fourth largest lake, the Aral Sea has shrunk so much that it is now split into two separate bodies of water-the northern or little Aral Sea and a larger southern body. Aralsk, once a thriving port town, is now 95 kilometers from the coast.Tackling the Water ProblemThe Population Action International Study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture. The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.(Y)The UN's World Summit on Sustainable Development and Rio Earth Summit of 1992 contribute to solving water supply problem.(Y)Africa and Middle East are the districts facing most severe water shortage.(N)The main reason for severe water problem in the near future is pollution.(N)According to the experts, the amount of water storage is far from sufficient.(N)The author argues that privatization of the publicly-run water services will solve the current water supply problem.(NG)Climate deterioration should take partial responsibility for the extinction of freshwater fish.(N)Actually the water in Aral Sea isn't salt.Two of the results of lacking water mentioned in the passage are _.
