2014英语四六级备考如何有效使用历年真题

　　Stress prompts the body to produce certain stress hormones. In short bursts these hormones have a positive effect, including improved memory function. They can help nerve cells handle information and put it into storage, says Dr. Bruce McEwen of Rockefeller University in New York. But in the long run these hormones can have a harmful effect on the body and brain.

　　Sustained stress is not good for you, says Richard Morimoto, a researcher at Northwestern University in Illinois studying the effects of stress on longevity, Its the occasional burst of stress or brief exposure to stress that could be protective.

　　1. The passage is mainly about ___A___.

　　A) the benefits of manageable stress

　　B) how to cope with stress effectively

　　C) how to avoid stressful

　　D) the effect of stress harmonies on memory

　　分析：综合各段开头反复重现的成分既为主题词，stress，不包含主题词的优先排除，四选项全部包含，转而查找主题句，文章开头出现引言，引言后的解释句中出现several studies suggest明确的结论性表达，引导全文主题的出现，A选项为文章主题句的同义改写，manageable对应rise to，benefits对应be good for。BC选项都以how to开头，而原文中并未提出解决方法，因此排除。D选项是针对第3段的细节信息，不能够概括全文，因此排除，而且请各位同学注意，D选项几乎完全照抄原文，像这样的选项在选之前请先思考一下，这2分拿得会不会太轻松。
