s suggestion. For one thing, recycling textbooks can save a lot of natural resources, which are used to make textbooks. And it can also save plenty of family expenses. For another, in western countries, recycling textbooks is very popular and it gives us a good example. But some have different opinions about it, for the content of the textbooks are often renewed. What’s more, it is not proper to make notes in the textbooks. In my opinion, this is a wonderful idea because this will do good to both the government and the families.
