Ⅴ. 短文填空(共10小题;每小题1分,满分10分)

选择适当的词(组)并用适当形式完成短文。每个词(组)只使用一次,其中有两个词(组)是多余的。

make use of  ,  never ,   say  ,   take ,        still ,       afford

“You can learn English more efficiently if you spend 20 minutes a day for a week than if you spend two hours a day.” This is what a teacher usually 71  when he tells his students how to allot(分配)their time. But is it true?

Suppose you have a bucket with a small hole in its bottom. Now you are asked to fill the bucket with the water in a basin. If you are too little a boy to lift the basin full of water, you are sure 72   a bowl or something alike. You will dip out the water from the basin with the bowl and pour it into the bucket .You may dip from the basin again and again. However, you will soon find that as soon as you pour a bowl of water into the bucket , most of the water 73  through the hole , so you are 74   able to fill up the bucket this way.

On the contrary , if you are an adult, you will 75  lift the basin and pour the whole basin of water into the bucket at once. Now, the bucket is full. Though the water in it is also leaking out, you at least have filled up the bucket with water. If you want to 76   the bucket full, you only have to add a bowl of water now and then .

The same is true of English learning. Let us 77  a simple example. If you learn 10 new words today, you are most likely to remember 9 tomorrow. But if you try to learn 30 words today, though you may forget far more than one word , you may 78  be able to remember 11 or 12 words tomorrow.

Day in and day out , you will be able to remember a large number of words, 79  you may forget some of them.

80  , the more time you spend at a time, the more you will learn on the whole. Of course, the amount of time you spend each time must be within the limit that you do not exhaust (使筋疲力尽)yourself .
