根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

     Let children learn to judge their work. 1_____ If corrected too much, he will stop talking. He notices a

thousand times a day the difference between the language he uses and the language those around him use.

Bit by bit, he makes the necessary changes to make his language like other people's. 2_____ They learn to

do without being taught to walk, run, climb, whistle, ride a bicycle, compare their own performances with

those of more skilled people, and slowly make the needed changes.

     But in school we never give a child a chance to find out his mistakes and correct them for himself. 3_____

we act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it

unless he was made to. Let him work out, with the help of other children if he wants it, what this word says,

what the answer is to that problem, whether this is a good way of saying or doing this or not.

     If it is a matter of right answer, as it may be in mathematics or science, give him the answer book. 4_____

Why should we teachers waste time on such routine work? 5_____ Let the children learn what all educated

people must some day learn, how to measure their own understanding, and how to know what they know or

do not know.

A. Children learn to do all the other things in the same way.

B. Let him correct his own papers.

C. Point out his mistakes.

D. We do it all for him.

E. We allow him to learn from other children.

F. A child learning to talk does not learn by being corrected all the time.

G. Our job should be to help the child when he tells us that he can't find the way to get the right answer.
