◾我们知道在具体考试中做考研阅读时，不需要每句话都读明白，一般除了重点的段首尾句以外，还需要同学们认真研读的当然是题眼句啦，也就是所谓的考点句。今天我们就一起看一下需要重点关注的阅读常考点。

◾因果关系处

◾因果句通常是作者进行分析或者得出结论的地方。英语句子存在前因后果和前果后因，考生一定要弄清楚谁导致谁。出题者为了考查考生的阅读能力和逻辑分析能力，经常会把含有因果关系进行颠倒，将“因变成了果、果变成了因”，考生需要注意辨别实际的因果关系，防止混淆。表示因果关系的词语有：

结果：thus, therefore, consequently, in consequence, as a result; lead to, attribute to, result, consequence, result in, cause等。

【真题回放1997-Text3】
We live in a society in which the medicinal and social use of substances (drugs) is pervasive: an aspirin to quiet a headache, some wine to be sociable, coffee to get going in the morning, a cigarette for the nerves. When do these socially acceptable and apparently constructive uses of a substance become misuses? First of all, most substances taken in excess will produce negative effects such as poisoning or intense perceptual distortions. Repeated use of a substance can also lead to physical addiction or substance dependence. Dependence is marked first by an increased tolerance, with more and more of the substance required to produce the desired effect, and then by the appearance of unpleasant withdrawal symptoms when the substance is discontinued.

Physical dependence on certain substances results from __.
[A] uncontrolled consumption of them over long periods of time
[B] exclusive use of them for social purposes
[C] quantitative application of them to the treatment of diseases
[D] careless employment of them for unpleasant symptoms

[真题解析]此题为细节题，根据题干Physical dependence定位到第四、五句，它们指出“频繁使用（Repeated use）一种物质也会导致身体成瘾或物质依赖。对药品的依赖性首先表现为不断增长的耐药量，要产生想得到的效果所需要的药品剂量越来越大，然后表现为当停止用药后，就会出现难受的停药症状。”题干当中的Physical dependence是将原文中physical addiction 和 substance dependence合成一个短语，A项是对这两句的概括，为正确答案。而lead to为因果关系指示词，可以引起关注。
