10、，均不符合题意。23. C undertake 意为“从事”。 其他选项中Aunderestimate “低估” ， Bundermine “削弱”Dundergo “经历”和 undertake 的区别在于，undertake 强调“主动做某事”。 Undergo 一般是被动地经历某事。24.

A absence 原来的句子为That is, the effects occur more often when the causes occur thanwhen the causes are (30)-but not always.此处显然需要一个形容词，“不在的，则应为形容词absent。31. A Thus 这里需要的承接上文的词应该具有 “因此” 的含义。 上面讨论的是研究中的 “或然性” 问题，也就是

13、，没有什么事情是绝对有把握发生的，社会研究中的因果关系一般都是probabilistic ，也就是发生的概率相对比较大。作者在后面举例说， “也就是说，那些刻苦读书的学生往往会取得好成绩，但是并不是每次都这样”。四个选项中唯一有承接关系的词是Thus。 So that 一般不用于句首。32.

16、9. B occur “发生” 。原句意思为：如果你能明白为什么有些事物是相互联系的，为什么有些固定的模式总是出现，你就可以不仅仅单纯地依靠观察和记忆，而更好地预测将来。Occur做 “突然发生”解时， 可以和 happen 相互交换使用。但是在本文中，occur 的主语为pattern。更侧重于“出现”的含义。因此不能用 happen 代替。 Incur 意为“招致；惹起”。例如 incurinconvenience “使别人不方面，给别人带来麻烦”等。40.
