文都考研英语老师为大家梳理一下1994年考研英语真题阅读Text 4的要点，涉及相对重要的词汇和短语的含义和用法以及典型长难句的分析。这篇文章主要探讨了癌症的防治问题。供2018考研学子参考。

　　“I have great confidence that by the end of the decade we’ll know in vast detail how cancer cells arise,” says microbiologist Robert Weinberg, an expert on cancer. “But,” he cautions, “some people have the idea that once one understands the causes, the cure will rapidly follow.

　　confidence后that引导同位语从句，解释说明抽象名词confidence;in vast detail“非常详尽”;arise“出现”;人物的身份不重要，重要的是人物的观点，因此我们重点关注引号之间的内容;主要关注But 后，首段转折往往与文章中心相关;caution“告诫”;idea后that也引导同位语从句，解释说明抽象名词idea;once“一旦”。

　　This year, 50 percent of the 910,000 people who suffer from cancer will survive at least five years. In the year 2000, the National Cancer Institute estimates, that figure will be 75 percent... But other survival statistics are still discouraging...

　　suffer from“遭受”;survive“幸存”;机构组织名称不用关注;estimate“估计”;discouraging“使人沮丧的，令人气馁的”，反义词encouraging“令人鼓舞的”;破折号后补充说明直接略过;生僻词汇完全不用关注。

　　With as many as 120 varieties in existence, discovering how cancer works is not easy... Anything from cosmic rays to radiation to diet may activate a dormant oncogene, but how remains unknown.

　　in existence“现存的，现有的”;discovering how cancer works为主语部分;activate“刺激，激活”;dormant“休眠的”;but how remains unknown“但是，如何激活的不得而知”。

　　The exact mechanisms involved are still mysterious, but the likelihood that many cancers are initiated at the level of genes suggests that we will never prevent all cancers... Environmental factors can never be totally eliminated; as Hayward points out, “We can’t prepare a medicine against cosmic rays.”

　　involved过去分词充当后置定语;likelihood“可能性”;that引导同位语从句，解释说明抽象名词likelihood;initiate“开始”;suggest“表明”;environmental factors“环境因素”;eliminate“清除”;分号前后语义并列，读懂其一即可;point out“指出”。

　　The prospects for cure, though still distant, are brighter.

　　“尽管遥远，但是治愈的前景越来越明朗。”

　　“First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells which are always responsible for at least part of the trouble. If we can understand how cancer works, we can counteract its action.”

　　control“控制”，也可以充当名词，self-control“自制”;determine“确定”，也可以表示“决定”，名词determination;be responsible for“对...负责”;counteract“抵消，中和”。
