     The question of what children learn,and how they should learn,is continually being debated and

redebated.Nobody dares any longer to defend the old system,the learning of lessons parrotfashion,

the grammarwithawhip system,which was good enough for our grandparents.The theories of modern

psychology have stepped in to argue that we must understand the need of children.Children are not

just small adults;  they are children who must be respected as much.

     Well,you may say,this is as it should be,a good idea.But think further.What happens?"Education"

becomes the responsibility not of teachers,but of psychologists.What happens then?Teachers worry

too much about the psychological implications of their lessons,and forget about the subjects themselves.

If a child dislikes a lesson,the teacher feels that it is his fault,not the child's. So teachers worry whether

history is "relevant" to modern young children.And do they dare to recount stories about violence?Or

will this make the children themselves violent?Can they tell their classes about children of different races,

or will this encourage racial hatred?Why teach children to write grammatical sentences?Verbal expression

is better.Sums?Arithmetic?No,reallife mathematical situations are more understandable.

     You see,you can go too far.Influenced by educational theorists,who have nothing better to do than to

write books about their ideas,teachers leave their teachertraining colleges filled with grand,psychologica

l ideas about children and their needs.They make elaborate (精心的),sophisticated (复杂的)

preparations and try out their "modern methods" on the longsuffering children.Since one "modern method"

rapidly replaces another,the poor kids will have had a good bellyful by the time they leave school.

Frequently the modern methods are so sophisticated that they fail to be understood by the teachers,let

alone the children;  even more often,the relaxed discipline so essential for the "informal" feelings the class

must have,prevents all but a handful of children from learning anything.

A. too much grammar was taught to children

2. What view do the modern psychologists hold?

A. Children must be understood and respected.

B. Children are small adults and know what they need.

C. Children are better off without learning lessons.

D. Education of children is the responsibility of psychologists.

A. They find that the children dislike the lessons.

B. They tend to blame students for their failure.

C. They do not pay enough attention to the actual lessons.

D. They no longer want to teach children history.

4. Grammatical sentences are regarded as unimportant because________.

A. it is better to use verbal expression only

B. words are said out of natural feelings only
