做好英语四六级的的阅读理解，光有词汇的积累还远远不够，阅读在于词汇，理解就要读懂句子啦，掌握各个句子之前的逻辑关系，这样才能顺利的理解文章的意思。下面就跟随出国留学网小编一起看看阅读中常考的逻辑关系——因果关系吧!
因果关系。
因：because、because of、for、as、since、in that、on account of、with
果：so、so that、therefore、thereby、as a result、hence、thus、consequently、accordingly
因果关系除了传统意义上的显性因果表达词外，隐性的因果同样是不可忽略的一个重要部分。

如：“The extreme serioue of desertification results from the vast areas of land and tremendous numbers of people affected，as well as from the great difficulty of reversing or even slowing the proce.”
在这段话中，根据result from可以推断出有因果关系，那如果是解释句子题时，选项中有因果关系就可以优先考虑。
C 反映，体现(果-因)：reflect、present、demonstrate、suggest、imply
D 考虑到：given、considering、in view of、thanks to、according to
He succeeded thanks to(in view of) his effort.
E 依赖于：rely on、depend on、resort to
He resorted to books when he had problems.
F 条件关系：when、once、as s...
