阅读理解。 The more we do a thing, the more we tend to like doing it; and if we do not continue to do it, we feel uncomfortable. This is called the force of habits, and the force of habits should be fought against. Habits, whether good or bad, are gradually formed. When a person does a certain thing, he is driven by some unseen force to do the same thing repeatedly, then a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible, to get rid of. It is therefore very important that we should pay great attention to the formation of habits. Children often form bad habits, some of which remain with them as long as they live. Older persons also form bad habits as long as they live, and sometimes become ruined by them. There are other habits which, when formed in early life, are of great help. Many successful men say that much of their success has something to do with certain habits in early life, such as early rising, honesty and so on. Among the habits which children should not form are laziness, lying, stealing and so on. They are all easily formed habits. Unfortunately, older persons often form bad habits, which should have been avoided. We should keep from all these bad habits, and try to form such habits as will be good for others and ourselves.
