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.
