题目内容
Water, which covers about 74 percent of the earth’s surface, is man’s most precious resource. Without it we cannot live. Clean water keeps us alive; polluted water means disease and death.Keeping our water pure is by no means an easy task but it is something that must be done.
Hong Kong once prided herself on being the “Fragrant Harbour”. However, these days, it is not certain if Hong Kong’s harbour could still be called “fragrant”. For, like many other places, Hong Kong has not been spared water pollution. A visit to Tolo and Victoria Harbour, or any of the beaches in Hong Kong is enough to make one aware of the ugly truth that Hong Kong waters are indeed polluted.
The great threat to our water is bacteria pollution. Another great source of water pollution is poisonous chemicals. These substances, which are found in industrial waste and agricultural pesticides, make up unseen dangers that enter biological food chains.
Pollution control is a continuing problem for the government. It is believed that the most effective form of control is legislation（立法）. Most importantly, the present laws on pollution should be given more force. On the other hand, no amount of legislation can effectively control pollution unless those concerned are properly educated about the danger posed by pollution.
While a great majority of Hong Kong citizens and residents seem to be greatly concerned about ways to control water pollution, it is discouraging to note that there are, in our midst, some people who remain apathetic（无动于衷）about the problem. In a recent radio programme conducted on what people in the streets thought about the water pollution problem, one apparently unconcerned person said, “What do I care about water pollution? I don’t drink polluted water. As long as the water I drink is not polluted, I’m not bothered. Water pollution is too big a problem and let’s leave it to the government.”
If all residents in Hong Kong will take such an indifferent attitude, all the government’s attempts to control pollution, let alone the anti-pollution legislation, will prove useless. The best form of pollution control each citizen can employ is to be aware of his surroundings. We hope that someday, the problem of water pollution in Hong Kong will cease to alarm us.

世纪百通期末金卷系列答案We are short of clean safe drinking water, which is found to be the ______ in many third world countries.
| A．example | B．event | C．case | D．object |
The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly. Man can only drink and use the 3% the water that comes from rivers and lakes. And we can’t even use all of that, because some of it has been polluted.
Now more water is needed. The problem is: can we avoid a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making study in this field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it’s already in use in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we’ll be in no danger of drying up.

Looking at the map of the world, and we can see that three quarters of the earth are covered by water. However, we are short of water, it sounds strange to you. But it is true. You see, 97% of the total water in the world is sea water, which is so salt that man can drink it. So only 3% of the water can be drunk or used for man. And the drinkable water comes from rivers, lakes and underground. Man even can’t use them completely, because the water contains icebergs and glaciers. All what is the worst is that water in some parts has been polluted or is being polluted. How can we drink? So something must be done to protect water from polluted.
