Task 1 Divide the sentences in each paragraph into sections, using “//’ between the topic sentence and the supporting sentences, and “/” between sections of the support.1. People often say that gold and silver are valuable, because they are wanted by everybody. But I say that books are even more valuable, because they are needed by everybody. Books are our friends. They introduce us to great men and great women. They take us to all the countries in the world. They tell us stories of all ages. Books are our friends. They teach us to know something about life and truth and science and philosophy. They increase our knowledge, enlarge our vocabulary, strengthen our character, and do many other things that silver and gold cannot do.2. Different books give different kinds of knowledge. Some are good and others are bad. Of course it is impossible for anyone to read all the books in the world, even if he spends his whole life in reading. Bad books contain evil thoughts. They are our enemies. Should one read them, the evil thoughts would poison his mind at once. But bad books, though harmful, are found in the hands of many young people. Accordingly, their way of living is changed, and they are ready to do all sorts of bad things. Good books, on the other hand, teach and help us to do good. They are companions. They are both instructive and inspiring.
