As we go about our everyday lives, we mentally attempt to place people in terms of their statuses. For example, we must judge whether the person in the library is a reader or a librarian, whether the telephone caller is a friend or a salesman, whether the unfamiliar person on our property is a thief or a meter reader, and so on. 　　The statuses we assume often vary with the people we encounter, and change throughout life. Most of us can, at very high speed, assume the statuses that various situations require. Much of social interaction consisits of identifying and selecting among appropriate statuses and allowing other people to assume their statuses in relation to us. This means that we fit our actions to those of other people based on a constant mental process of appraisal and interpretation. Although some of us find the task more difficult than others, most of us perform it rather effortlessly. 　　A status has been compared to ready－made clothes. Within certain limits the buyer can choose style and fabric. But an American is not free to choose the costume (服装) of a Chinese peasant or that of a Hinduprince. We must choose from among the clothing presented by our society. Further more, our choice is limits to a size that will fit, as well as by out pocketbook (钱包). Having made a choice within these limits we can have certain alterations made, but apart from minor adjustments, we tend to be limited to what the stores have on their racks. Statuses too come ready made, and the range of choice among them is limited. 1．In the first paragraph, the writer tells us that statuses can help us ________.
