Most parents, I suppose, have had the experience of reading a bedtime story to their children. And they must have 【B1】 how difficult it is to write a 【B2】 children’’s book. Either the author has aimed too 【B3】. so that the children can’’t follow what is in his (or more often, her) story, 【B4】 the story seems to be talking to the readers. The best children’’s books are 【B5】 very difficult nor very , and satisfy both the 【B6】 who hears the story and the who 【B7】 it. Unfortunately, there are in fact 【B8】 books like this, 【B9】 the problem of finding the right bedtime story is not 【B10】 to solve. This may be why many of books regarded as 【B11】 of children’’s literature were in fact written for 【B12】. "Alice’’s Adventure in Wonderland" is perhaps the most 【B13】 of this. Children, left for themselves, often 【B14】 the worst possible interest in literature. Just leave a child in bookshop or 【B15】 and he will 【B16】 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 【B17】 of teachers and right-thinking parents. Perhaps we parents should stop trying to brainwash children into 【B18】 our taste in literature. After all children and s are so 【B19】 that we parents should not expect that they will enjoy the 【B20】 books. So I suppose we’’ll just have to compromise over that bedtime story.
