托福考试对留学生来说都是很重要的，对考生的阅读能力具有高的要求，本文英匠教育小编为各位考生带来托福阅读高分技巧之寻找信号词，希望对大家有所帮助。
1 信号词之原因
例如reason,cause,since,in that,as,because,thanks to,owing to,解释说明某一事物或事件，往往会蕴含重要信息。如'since the lifetime of a planet like ours is several billion years,we can expect that…'该句是之后简答题'what is the life expectancy of Earth'的答案信息来源，如果考生只定位Earth,那就很有可能失分，因为原句对Earth做了同义替换的表述，而since这个信号词则提示了答案所在的地方。
2 信号词之结论
例如thus,therefore,so,hence,consequently,as a result,这些词往往是对前面所论述的总结归纳，例如'Tortoises therefore represent a remarkable double return’，该句出现在整篇文章的末段首句，很明显是对前文的总结概括，高度浓缩了信息。最后的主旨选择题，就是对该句的改写：'they have made the transition from sea to land more than once’。
3 信号词之转折
例如however,but,by comparison,nonetheless,nevertheless，这些词往往表示文章观点或方向的重大转变，重点应该关注信号词后面的内容。如‘this definition implies that iconoclasts are different from other people,but more precisely,it is their brains that are different in three distinct ways’，前半句指出iconoclasts异于常人，用but转折词，强调指出区别的关键地方。这也是选择题‘iconoclasts are distinctive because…'的出题方向。
4 信号词之让步
例如although,though,while,whereas,whilst等连接的句子，后半句才是引出的话题和强调内容。如'He accurately predicted that Venus would cross the face of the Sun in both 1761 and 1769--though he didn't survive to see either’，前半句讲述他精确预测金星跨越太阳的两次时间，后半句用though引出让步内容，他没有看到任何一次。判断题中‘Halley observed one transit of the planet Venus’主要就是以原文定位句的后半句为判断依据。
