What do you read when you are travelling by train or bus? What are other people reading? Perhaps a woman sitting near you is reading a love story. A man is reading a serious biography(自传) about a president. And there's a student reading an English textbook.

    What do their choices(选择) say about them? Do you think you can know them by what they are reading? I have got to tell you that your feelings of them may be quite wrong. The woman reading the love story could be a lawyer. She just wants a light read to take her mind off work. The man reading the biography wants you to think that he is very clever. The student reading the textbook isn't a student at all. She's an English teacher.

    Publishers(出版商) know that some people care what they read on trains or buses and so they put out different types of covers. For example， books about Harry Potter have a cartoon cover for young readers and then another more serious cover for grown—ups.

    So next time you are on a train， look around and see what other people are reading， but don't jump to any conclusions(结论). You will be wrong maybe.

Here is a sentence that you could say， “Don't judge（判断） a book by its cover”.
