  英语六级听力短文:17 Controling Cancer

  There are two main causes of cancer: heredity and environment. We can do nothing to change our heredity, that is, the basic physical characteristics that are passed on to us by our parents. However, we can do a great deal to control our environment, which may account for eighty to ninety percent of all cancers. Enviromnental pollution can be divided into two kinds: personal and nonpersonal. Personal pollution may be defined roughly as unhealthy habits such as smoking, drinking, and eating the wrong foods. Clearly, with enough will power we can control this personal environment. nonpersonal pollution, on the other hand, refers to those things which are beyond our individual control. One example would be industrial pollution, which is very hard to control because of the expense involved. It would be expensive in terms of profits and, perhaps, jobs.The American automobile industry, for example, resisted the law requiring smog-control devices because it feared the added expense would reduce profits. Nevertheless, some laws protecting the environment have been quite successful in reducing pollution.
