托福阅读中的逻辑关系词

托福阅读中的逻辑关系词

作者在阐述观点时会大量使用逻辑关系词来组织结构，展开论证。在阅读过程中，充分利用逻辑关系词（也称之为语言信号词）是定位主旨和查找细节信息的重要阅读应试技巧之一。通过寻找信号词可以寻找线索，快速定位答案所在。常见的信号词包括以下四类：

-Comparison 比较关系词

-Cause and effect 因果关系词

因：because、because of、for、as、by、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。

-隐性因果：

- A 导致(因-果)：cause、reason、lead to、give rise to、result in、render、make、let、ask、push、stimulate、fuel、produce、tempt、encourage、draw、trigger

如：The increased pressures of expanding population have led to the removal of woody plants so that many cities and tow are surrounded by large areas

completely lacking in trees.

在这段话中，有lead to表示了导致的意思，即结果，而so that更进一步表示了后面的结果，所以可以充分判定这段话有因果关系的逻辑。

- B 由…而来(果-因)：result from、derive from、originate from、initiate from、stem from、be attributable to、attribute to

如：“The extreme serious 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 process.”

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、show、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.
