雅思阅读技巧之寻找信号词的正确姿势
雅思阅读考试考查的不仅是对文章的理解，还有许多文章语段中的详情，通过题干去锁定关键词信息对考生来说尤为重要。

不过雅思阅读题会设置许多的同义词转换，查找答案的难度就提高了一个level，怎么办，这时候文章中的信号词变成了救命稻草，一起来了解一下如何查找雅思阅读中的信号词吧。

雅思阅读信号词之特别信号词
特别的信号词，一般都比较简单识别，假如遇到题目中涉及到，一般大写字母开头的人名，地名，专出名词，以及特别印刷体和黑体，这些词在英语文章中显得尤为突出，往往也是题干中关键词的原词定位。

例如 the US Congress voted NASA $10 million per year for ten years to conduct a thorough search for the extra-terrestrial life 这句话，出现了US Congress, NASA 专出名词信号词，极有可能成为定位的讯息。

确实，推断题型中有一题the NASA project attracted criticism from some members of Congress. 就是依据这两个信号词精确地回到原文定位。

雅思阅读信号词之一般信号词
雅思阅读作为一项专业的语言水平测试，当然不能只依靠简单识别的特别信号词，文章中的一般信号词对于解题可谓是功不行没。

1)信号词之缘由
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，假如考生只定位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，该句出如今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。

最终的主旨选择题，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，重点应当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，强调指出区分的关键地方。

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 didnt survive to see either，前半句讲解并描述他精确预报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。

推断题中Halley observed one transit of the planet Venus主要就是以原文定位句的后半句为推断根据。

5)信号词之举例
例如for example, for instance, that is to say, such as, include, 后面引出具体事物的具体例子，同时原文中破折号和冒号也有异曲同工之妙，对前面的内容补充说明。

如in other worlds, the life form we are looking for may well have two green heads and seven fingers, but it will nevertheless resemble us in that it should communicate with its fellows, be interested in the Universe, live on a planet orbiting a star like our Sun, and perhaps most restrictively, have a chemistry, like us, based on carbon and water. 整句话都在解释说明该段的第二个假设we are looking for a life form that is pretty well like us，所举的例子也是推断题SETI scientists are trying to find a life form that resembles humans in many ways 的推断根据。

6)信号词之顺序
例如first, second, finally, eventually, later, then, next 等，表达出文章内容的规律性与进展性。

如In discussing whether
we are alone, most SETI scientists adopt two ground rules. First,Second，使用first 和second这两个序数词，清楚规律地讲解并描述了两个重要的假设。

这两个信号词，也是这篇文章heading 题型段落大意的重点提示。

7)信号词之比较级
例如more, most, -est, best, better,exclusively, extremely, superior, preferable，表示事物之间的比较，也是文章要强调的地方。

如one part is a targeted search using the worlds largest radio telescopes, the American-operated telescope，该句的the worlds largest radio telescopes 对应了题目中the worlds most powerful radio telescopes，答案信息就在这里。
