发达国家大量减免关税的目的是希望实现贸易自由化，从而促进发展中国家的发展。()

A child who has once been pleased with tale likes, as a rule, to have it retold in identically the same words, but this should not led parents to treat printed fairy stories as sacred texts. It is always much better to tell a story than read it【41】of a book, and, if a parent can produce【42】in the actual circumstances of the time and the individual child, is an improvement on the printed text, 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【43】, one would have to show in a controlled experiment that children who have read fairy stories were more often guilty of cruelty than those who had not. Aggressive, destructive, sadistic impulses every child has and,【44】the whole, their symbolic verbal discharge deems to be rather a safety valve than an incitement to overt action. As to fears, there are, I think, well-authenticated cases of children【45】dangerously terrified by some fairy story. Often, however, this arises from the child having heard the story once. Familiarity with the story by repetition turns the pain of fear【46】the pleasure of a fear face and mastered.
There are also people who object to fairy stories on the grounds【47】they are not objectively true, that giants, witches, two-headed dragons, magic carpets, etc, do not exist, and that, instead of indulging, his fantasies【48】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 cases【49】sound there should be full of madmen attempting to fly from New York to Philadelphia on broomstick【50】covering a telephone with kissed in the belief that it was their enchanted girl- friend. No fairy story ever claimed to be a description of the external world and no such child ever believed that it was.
