Most parents, I suppose, have had the experience of reading a bedtime story to their children. And they must have how difficult it is to write a children's book. Either the author has aimed too . , so that the children can't follow what is in his (or more often, her) story, the story seems to be talking to the readers. The best children's books are very difficult nor very simple, and satisfy both the who hears the story and the adult who it. Unfortunately, there are in fact books like this, the problem of finding the right bedtime story is not to solve. This may be why many of books regarded as of children's literature were in fact written for . “Alice's Adventure in Wonderland” is perhaps the most of this. Children, left for themselves, often the worst possible interest in literature. Just leave a child in bookshop or and he will more willingly choose the books in an imaginative way, or have a look at most children's comics ( 连环画 ), full of the stories and jokes to which both teachers and right-thinking parents . Perhaps we parents should stop trying to persuade children into our taste in literature. After all children and adults are so that we parents should not expect that they will enjoy the books. So I suppose we'll just have to compromise（妥协） over that bedtime story.
