能力提升训练

Ⅰ.语法填空

阅读下面短文，按照句子结构的语法性和上下文连贯的要求，在空格处填入一个适当的词或使用括号中词语的正确形式填空。

The world is not hungry, but it is thirsty. It 1 (seem) strange that nearly

3/4 of the earth is covered 2 water while we say we are short of（短缺）water.

Why? Because about 97% of water on the earth is sea water which we can't drink or

3 (use) for watering plants directly（直接地）.Man can only drink and use the other

3% of the water that comes 4 rivers and lakes. And we can't even use all of that,

because some of it is 5 (pollute).

Now more water is needed. The problem is: Can we avoid (避免) a serious water

shortage later on? First, we should all learn how 6 (save) water. Turn the tap

off while 7 (brush) your teeth, washing your hands,doing the dishes, and so on.

Second, we should find 8 the ways to reuse it. Scientists always make studies

in the field.Today, in most large 9 (city) water is used only once and then runs

to the sea or rivers. But it can be used again. Even if(即使) every large city reused

10 (it) water,still there would not be enough. From now on, everyone should save

the water.

1._____2._____3. _____4._____5.________6._____7._____8._____9._____10._____

Ⅱ.阅读下面短文，从短文后所给的五个选项中选出能填入短文空白处的最佳选项，使短文通顺、连贯，意思完整

We should not use more water than we actually need. If we do, we will not have

enough water in the future. 1 It is not a difficult question to answer. If we

remove more fresh water than nature replaces, we have taken too much.

Many cities run campaigns(运动) to get people to stop wasting water. They show

them ways they can cut back on water use. 2 What's more, they carry out programs

that offer money to reduce water use. For example, they give people shower heads

and toilets that use less water. 3

Another threat (威胁 ) to our water supply is pollution.When our sources of fresh

water get polluted, we can no longer use this water. This also endangers (危及) the

animals that depend on the water.

4 We can save lots of water by not letting taps(水龙头) run

while we brush

our teeth or by turning off taps right after washing hands. By collecting cold water

when we're taking warm showers, we can also save water. 5 In this way, we can

make full use of water.

A.However, just how much is too much?

B.There are several things we can do to save water.

C.Finally, they make laws to control the use of water.

D.We don't have to let the cold water run until it gets warm.

E.They also increase water bills for people who use too much.

1._____ 2._____ 3. _____ 4._____ 5.________
