在托福阅读中，逻辑是我们理解文章组织结构，明确作者思维过程的重要参考。尤其是逻辑会为大家的托福阅读解题带来极大的方便，甚至成为解题的关键。为了熟悉在托福阅读文章中的逻辑关系，前程百利小编为考生带来托福阅读逻辑中的因果关系。希望可以对大家有所帮助。
先看一下特征词：
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。
隐性因果：
A.导致(因-果)：cause, reason, lead to, give rise to, result in, render,
make, let, ask, support, push, stimulate, spark, spur, fuel, produce, be
responsible for
如：The increased pressures of expanding populations have led to the
removal of woody plants so that many cities and towns are surrounded by
large areas completely lacking in trees and shrubs。
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 responsive to, be attributable to
如：“The extreme seriousness 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, present, demonstrate, suggest, imply,
show This result demonstrates that…
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 soon as, as long as As soon as he got the
money, he would leave the country at once
G.分词短语，不定式做状语：Failing in the final exam, she cried
以上就是前程百利小编为考生带来的托福阅读逻辑中的因果关系。从文章中的介绍可以了解到，在文章中的因果关系并不一定是大家熟悉的显性因果，更多的可能会是有因果关联的隐形因果。希望大家在阅读中善于发现，总结。预祝大家托福考试取得好成绩!
