    Water

    Earth is like a big blue marble.From high above the Earth and from the moon,the planet gleams and shines.The blue water in the oceans and seas of the Earth makes a dramatic image.The white clouds above the Earth add beauty to the picture.Water is the source of this beauty and the source of life on Earth.It is the reason people can live on this planet. Water is everywhere.(46)_______.It is in the soil,the ground that grows the food.Water is in rock deep under the ground, in natural holding areas一in storage.In a real sense,water keeps Earth alive.
    Nature has an unchanging amount of water. Nature has a perfect system for recycling water. (47)_____.It falls as rain.Then it goes to one of three places.It might sink slowly through the soil into the natural holding areas in the rock.(48)_______一by becoming vapor,or gas.It might run off into streams,rivers and oceans.By itself,nature can keep the balance and provide plenty of clean water for us.Nature recycles water.
    However,people cause problems for this natural recycling system.Nature's recycling system can work well(49)________.Some ways that people upset nature are easy to understand.For example, dirty sewage（污水沟系统）water from homes and factories must not mix with drinking water. People get sick from drinking contaminated water. Sometimes water from factories goes into streams and rivers.It enters into the groundwater. It can flow into lakes too.This kind of contamination from industry(waste water from factories) can be dangerous for people.If water contains poisons and chemicals,it is poison.(50)________;some poisons kill people as well as birds and animals.Without knowing,people can upset nature's recycling system.
    Lakes and rivers add beauty to the world. People enjoy water for entertainment purposes,too. People enjoy swimming and playing in the cool water of a lake in the summer. They like to ride on boats on rivers.Many people enjoy catching fish in the rivers.They fish for food and for sport.However,in some places,the water of the lakes and rivers is no longer safe.These rivers and lakes are contaminated.The fish are dying because of the chemicals from farms and factories.People cannot swim in the polluted water.

    _________（49）
    A:Poison makes people sick
    B:It is in the air that people breathe
    C:We can not live without water
    D:Water is used again and again
    E:only if people work with the system and not against it
    F: It might disappear into the air quickly

    答案：E
    解析：
    文章前一句说水到处都存在，那么后一句应该跟此句有关系，而且下一句说“它存在土壤里”，因此选项B项“它在人们呼吸的空气里”是最合适的。
    文章前一句说大自然有一个循环水的完美系统，那么后一句相关的选项只有D项“水可以一遍又一遍地反复利用”。
    从本句的前后句看这是一个排比句式，三句话都是以it might开头，而后半句“变成蒸汽或水汽”更证明选项F是最合适的。
    本句前一句讲人们会引起大自然循环体系的问题，那么空格里应该填入人们怎么做大自然的循环体系才能很好地运转。因此选项E“只有顺着这个系统，而不是对它造成破坏”是最佳选择。
    本句前后句的关键词是“poison"，因此判断只有选项A“毒物使人生病” 最合适。

  • 第4题：

    The water we drink and use is running short in the world.We all have to learn how to stop wasting our limited water.One of the steps we should take is to find ways of reusing it.Experiments have already been done in 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 factory.There it can be filtered and treated with chemicals so that it can be used again,just as it were fresh from a spring.
    But even if every large city purified and reused its water,we still would not have enough.Then we could turn to the oceans.All we’d have to do to make use of the seawater on earth is to get rid of the salt.This process is called desalinization,and it is already in use in many parts of the world.
    The way to stop wasting our limited water is to________.

    A.do experiments with water
    B.purify the used water and reuse it
    C.use fresh water once again
    D.make use of seawater

    问答题
    Practice 4　　The problem of pollution is also of great social concern. Continued population increase, accompanied by a rise in the level of living standards, not only threatens to exhaust American resources but pollutes the environment to such an extent that production in the thickly settled area is impossible without damaging the health of the local residents.　　Smog, once an urban annoyance, is now recognized as a health risk, and the automobile has been pinpointed as the principal culprit. Heavy industries have been blamed for river, soil, air, noise and visual pollutions. DDT and other chemical remedies have been doing more ecological harm than the good that they may have brought along.　　Several decades ago, Americans dumped raw sewage into rivers and many industrial plants are now still dumping chemical pollutants into lakes, rivers and oceans. Oceans used to be and are still being considered to be a reserve of seafood. Today, after the oceans have become the home of all pollutants, this use of the oceans is being reduced at an alarming rate.　　The worst pollution threat is concentrated in and near large cities. There the people-made pollutants increasingly surpass the ability of air and water to dilute (冲淡；稀释) the contaminants (污染物) to safe levels. The natural ecological cycle depends on plants, which absorb some pollutants and release oxygen to the air. But near large cities, natural vegetation becomes scarce, and introduced trees, ornamental shrubs and gardens are far from adequate in absorbing motor vehicle and industrial air pollutants. Finally, some pollutants, most notably atomic waste, may continue to contaminate air, land, and water for thousands of years. Therefore, ecocrisis—ecocatastrophe or ecocide—has been for some time one of the major concerns of not only the ecoactivists and environmentalists, but of many scientists of other fields and the government authorities of many countries as well.

    正确答案：
    【参考译文】
    污染问题也受到了社会的极大关注。生活水平在提高,人口在持续增长,这不仅预示着美国资源面临枯竭,而且污染环境到了极严重的地步:人口密集区的工业生产与当地居民的健康已成为不可调和的矛盾。
    烟雾,原先不过是居民的一件烦恼事,现在被公认为危害健康的大敌。汽车已被指控为损害健康的罪魁祸首。重工业因污染河流、土壤、空气、产生噪音和妨碍人们的视觉而备受指责。DDT及其他化学药剂对生态的影响是弊大于利。
    几十年前,美国人把未经处理的污水倒入河流,而许多工厂如今仍在把化学污染物倒入湖泊、江河和海洋。人们一向认为海洋是海产品的宝库。今天,海洋已成为一切污染物的集中地之后,海产品正以惊人速度缩减。
    大城市及其周边是污染最严重的地方。在那里,人为污染物的扩散超过了空气和水将污染物分解稀释到安全水平的能力。自然界生态循环依赖于植物;植物吸收一些污染物,把氧气释放到空气中。但邻近大城市的地区,天然植被日见稀少,而移植的树木、观赏灌木及花园又远不足以吸收机动车辆和工业带来的空气污染物。最后,有些污染物,尤其是臭名昭彰的原子能废料,可能会继续污染空气、土地和水达几千年之久。因此,生态危机——也称为生态灾难或生态灭绝——一段时期以来不仅是生态活动家和环保主义者关注的主要问题,而且引起了其他领域许多科学家和许多国家的政府当局的重视。
