　　Passage One
　　Questions 51 to 55 are based on the following passage:
　　Statuses are marvelous human inventions that enable us to get along with one another and to determine where 　we "fit " in society. As we go about our everyday lives, we mentally attempy 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 lift. Most of us can , at very high speed , assume the statuses that various situations require. Much of social interaction consists 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 of a Chinese peasant or that of a Hindu prince. We must choose from among the clothing presented by our society. Furthermore, our choice is limited to a size that will fit, as well as　by our pocketbook Having made a choice within these limits we can have certain alterations made, but apart from minor abjustments , 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.
