A Thirsty World
Three-fourths of the earth’s surface is covered by water, some of which is frozen and most of which is salty. In fact, less than one percent left for all the living things.
Now fresh water is becoming scare, but more and more is needed because of the increasing number of people. Some industries also use amounts of fresh water in the production of things such as steel, paper, and rubber. These factories have polluted water flow into rivers without making it clean. What’s more, people in the city have much dirtied water piped into ditches after cooking every day.
Scientists estimate that the need for fresh water will have doubled by the year 2003. This means that we must find new ways of saving it or producing it. Some nations have worked on the problem and are already sharing their information with others. They are trying to keep their rivers from being polluted. Deep wells are also being dug, and rainwater is being collected in huge artificial lakes. In one way or another, they hope to provide enough water to satisfy the needs of their people. For example, one important way of producing water is to distill(用蒸馏法提取) it from sea water. After the salt has been removed, sea water can be used not only for drinking but also for industry and irrigation. However, the equipment for distillation process is very expensive. Distilled water might be as dear as gold if pollution goes on.

We Need a Green Environment
Though the earth is covered by water, we are living in a world thirsty for water for many reasons. Therefore, to save water, some nations develop new projects, such as using distillation process to make fresh water.
When we explore into the reasons, we find that much pollution is caused by things that benefit people. For example, air and noise pollution is produced by cars that carry us fast and conveniently. In fact, people keep polluting the earth this way or that. It is necessary for government to pass laws to stop polluting the environment. For example, factories should be ordered to make the dirty water clean before it flows out into rivers. Besides, people should be more aware of this serious problem and take actions to protect our earth. As for us students, deeds are louder than speech. We should stop littering, and try to use those things that can be recycled. Only when we realize the importance can we win the fight against pollution.

阅读下面的短文，然后从A-F选项中，为每一小段选择合适的标题, 并把答案写在答案卷上。
|
A. The most common problem is a “wandering” mind B. Selective listening is also a mental barrier C. Listening isn’t an easy skill to master D. Attitude can also influence good listening E. Noise and background music makes listening more difficult F. Listening is also related to the level of the listener’s knowledge |
1._____________
Listening is not as easy as someone thought. Even good listeners may recall only fifty percent of what they hear. Retention, the ability to remember and recall information, decreases about twenty to twenty-five percent after a few days. So no matter how well you listen in class, you’re always going to have to refresh your memory before a test! Unfortunately, many people have poor listening habits, and little listening training. To improve your listening skills, it’s important to understand what causes poor listening.
2.___________
If you find it difficult to concentrate solely on what a speaker is saying, there’s a good reason. The mind processes information much faster than a speaker can speak. The brain can process over 500 words per minute, while the average speaker talks at a rate of 124 to 250 words per minute. That means the mind can hear what’s being said and can think about something else at the same time.
3.____________
If you have a negative idea about the speaker or the topic, you’ll find it difficult to listen attentively. Hostile or captive audiences often have more difficultly listening than do favorable or voluntary ones.
4.____________
If a speaker speaks “above the heads” of an audience, people find it difficult to concentrate. Speakers who use unfamiliar words or who use incomplete explanations make it more difficult to listen. Speakers who “speak down” to audiences, failing to acknowledge what the audience already knows, also create mental blocks.
5.___________
When people listen selectively, they simply block out what they don’t want to hear. For instance, many people have habits that are dangerous to their health, like smoking. However, they often choose to block out what a speaker says about health risks. They may listen to a speech and think that the speaker’s message applies to other people, not them. In other words, they hear what they want to hear and ignore what they don’t want to hear.
