专业英语四级分类模拟330_真题-无答案

专业英语四级分类模拟330 (总分182,考试时间90分钟) WRITING 1. Read carefully the following excerpt on youth crime argument in the USA, and then write your response in NO LESS THAN 200 words, in which you should: ● summarize the main message of the excerpt, and then ● comment on whether young criminals are born or not. You should support yourself with in formation from the excerpt. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. Juvenile delinquency: nature or nurture? Being a juvenile in any one"s life is part of the stage of development. The behavior patterns of juveniles are influenced in part by what goes on in the environment in which they live. Every stage of development has transitions. Family members, friends, and peers all influence these times of transition for the juvenile. It is sometimes accompanied by a desire for material things, fashion, peer pressure, cash and more. At times, the demands of wants and needs are intensified by a society that consists of high mobility, social change, and is materialistic. Also, social changes can create anxiety and disillusionment for adolescents and thus **mit delinquent acts. Obviously, human beings tend to develop in different stages until they become adults. One of these stages is the adolescent stage. When humans are in the adolescent stage, they are considered juveniles. When a juvenile does something wrong, contrary to the laws or norms of the society, such as acts of vandalism, theft, drug related activity, arson or other anti-social behavior, he/she is then considered a juvenile delinquent. On the other hand, some scientists believe some are born to be criminals. Some teenagers may suffer from psychopathy—a disorder suffered by many (but not all) violent criminals—is characterized by an inability to "empathise". The researchers, based at King"s College London"s Institute of Psychiatry, said the differences in psychopaths" brains mark them out even from other violent criminals with anti-social personality disorders (ASPD), and from healthy non-offenders. Psychopaths have physically different brains from "normal" people—and may be born to kill. The new finding may mean that there is simply no point treating psychopaths with current "behavioural" treatments. 2. Should we always tell the truth? The following are the supporters" and opponents" opinions. Read carefully the opinions from both sides and write your opinion in about 200 words, in which you should first summarize briefly the opinions from both sides and give your view on this issue.
