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.

We are short of clean safe drinking water, which is found to be the ______ in many third world countries.

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.
【小题1】The world is thirsty because ___________.

A．3/4 of the earth is covered with water

B．we have enough sea water

C．we haven’t used all the water in rivers and lakes

D．about 97% of water on the earth can’t be drunk or used for watering plants directly

【小题2】Which of the following is TRUE?

A．3% of drinkable water on the earth is from rivers and lakes.

B．75% of water on the earth is in the sea.

C．97% of the earth is covered with water.

D．3% of water on the earth is sea water.

【小题3】From the passage we learn that __________.

A．if every city reuses its water, we’ll be in no danger of drying up

B．man can only drink and use about 25% of water on the earth

C．today in most large cities water is used only once

D．water can be used only once

The UN passed a rule in the year 2004 to improve the quality of drink water and reduce deaths caused by drinking unhealthy water each year. The UN has already worked out the specific plan to reduce half of the number, that is, five thousand. The UN announced in the world there are about 1/6 of the world population can't meet the sanitation regulation of drinking water.

The water we drink and use is running short in the world. We all have to learn to stop wasting our quite limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done on this field. Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying(净化)factory. There it can be filtered(过滤) and treated with chemicals so that it can be used again , just as it were fresh from a spring. But even large cities purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we would have to do to make use of seawater on earth is to get the salt out of it. This method has already been used in many parts of the world.

47. The way to stop wasting water is to ________ .

A. do experiments with water

B. purify the used water and reuse it

a. to have the used water filtered b. to put chemical in it

c. to pipe it to the user

d. to pipe the used water to be purified in a factory.

A. dabc B. bcda C. bdca D. dcba

49. There wouldn't be enough water for us if we didn't ________ .

A. turn to the ocean for more water

B. reuse used water and make use of seawater

C. make fresh water from the seawater

D. take steps to reuse all water on earth

50. The word "it" underlined in the last paragraph refers to ________ .

A. the process of collecting salt from the ocean

B. the process of getting rid of the salt in seawater

C. purified water

D. seawater

I have to admit: I don’t flush the toilet every time I go to the bathroom. In fact, I firmly believe “If it’s yellow, let it mellow; if it’s brown, flush it down.”

I’m sure a lot of it has to do with the fact that I work at home. Alone (well, except for the cats and dogs). All day. And I drink a lot of water, which makes for many trips to the bathroom.

Another thing I have to admit: I also try to use very little toilet paper. I wash my hands after, though. Every time. (So maybe the water I don’t use flushing makes up for the water used to wash my hands?)

Ironically, my husband, who only uses toilet paper when necessary, always flushes. But he doesn’t seem to mind that I don’t flush every time. Or, at least not enough to file for divorce yet.

When I’m at home alone I do not flush every time I pee(小便). My husband hates that, though, so when he’s home, I flush a little more often. I grew up doing that because I had a family that lived with huge tanks and you have to do it that way because it’s easier on the system, so it doesn’t bother me. I do flush when I’m out in public, at people’s houses that don’t have big tanks and when we have company!

Not always. But I have 4 children who are always hanging from the door knob（球形捏手） while I pee anyway. So I’m lucky I have time to wash my hands after. The average toilet uses 8 gallons of water per flush! Much less than what it takes to wash my hands after. (just saying)

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.
