第8题

A child who has once been pleased with a tale likes, as a rule, to have it retold in identically the same words, but this should not lead parents to treat printed fairy stories as sacred texts. It is always much better to tell a story than read it out of a book, and if a parent can produce what, in the actual circumstances of the time and the individual child, is an improvement on the printed test, so much the better.

A charge made against fairy tales is that they harm the child by frightening him or arousing his sadistic impulses. To prove the latter, one would have to show in a controlled experiment that children who have read fairy stories were more often g0.ilty of cruelty than those who had not. Every child has aggressive, destructive, sadistic impulses and, on the whole, their symbolic verbal discharge seems to be rather a safety valve than an incitement to overt action. As to fears, there are I think, well-authenticated cases of children being dangerously terrified by some fairy story. Often, however, this arises form. the child having heard the story once. familiarity with the story by repetition turns the pain of fear into other pleasure of the fear faced and mastered.

There are also people who object fairy stories on the grounds that they are not objectively true, that faints, witches, two-headed dragons, magic carpets, etc, do not exist, and that, instead of indulging his fantasies in fairy tales, the child should be taught how to adapt to reality by studying history and mechanics. I find such people, I must confess, so unsympathetic and peculiar that I do not know how to argue with them. If their ease were sound, the world should be full of madmen attempting to fly from New York to Philadelphia on a broomstick or covering a telephone with kisses in the belief that it was their enchanted girlfriend.

No fairy story ever claimed to be a description of the external work and no sane child had ever believed that it was.

The author considers that a fairy story is more effective when it is ______.

A．repeated without variation

B．treated with reverence

C．adapted by the parent

D．set in the present
