Most parents, I suppose, have had the experience of reading a bedtime story to their children.And they must have 1 how difficult it is to write a 2 children's book.Either the author has aimed too 3 , so that the children can't follow what is in his (or  more often, her) story, 4 the story seems to be talking to the readers.

The best children's books are 5 very difficult nor very simple, and satisfy both the 6 who hears the story and the adult who 7 it.Unfortunately, there are in fact 8 books like this, 9 the problem of finding the right bedtime story is not 10 to solve.

This may be why many of books regarded as 11 of children's literature were in fact written for 12 .“Alice's Adventure in Wonderland”is perhaps the most 13 of this.

Children, left for themselves, often 14 the worst possible interest in literature.Just leave a child in bookshop o 15 and he will 16 willingly choose the books written in an imaginative way, or have a look at most children's comics, full of the stories and jokes which are the 17 of teachers and right-thinking parents.

Perhaps we parents should stop trying to brainwash childrensintos 18 our taste in literature.After all children and adults are so 19 that we parents should not expect that they will enjoy the 20 books.So I suppose we'll just have to compromise over that bedtime story.
