信号词一：顺接和递进
例词：also, furthermore, moreover, what is more, in addition…
考点：And Western scientists are starting to draw on this wisdom…(C6, P28, T31找标题)
解析：And在这句话开头，有一定的递进含义, this wisdom则是指代了前面一句话出现的their wealth of traditional knowledge(因纽特人传统的知识)，所以这两句话有紧密的联系，同学们在读题的时候要通过发现信号词，然后发散地看它的前后句，最后把考点考察的意思补充完整。
信号词二：对比和转折
例词：however, but, although, nevertheless, on the other hand, by comparison…
考点：However, we believe that credit must be extended in association with other types of support that help participants develop critical life skills as well as productive businesses.(C4, P66, T13主旨选择题)
题目中出现了conclude的字眼，总结段落一般是在文章的最后，然而带有转折信号词however这句话，显然就是文章的考点所在。
信号词三：相似
例词：similarly, in other words, that is, put another way…
考点：In other words, we became aware of the obvious fact that there were‘limits to growth’.(C4, P97, T32分类题)
解析：In other words是解释，换一种说法，通常会以更加简单易懂，清晰的话语陈述出难点，常常难点就是雅思阅读考点出没的地方。
信号词四：时间先后
例词：firstly, second, next, then, now, later, since, eventually, finally…
考点：Three factors are involved in this change. First is an awareness of the severity of the problem. Second, a number of resources to help tackle bullying have become available in Britain…Third, there is evidence that these materials work, and that schools can achieve something.(C6, P94, T30选标题)
解析：段落结构很清楚，主要是因为有表达顺序的信号词First、second、third，让我们认识这段是在讲，侍强凌弱这种现象已经开始改变，主要是从三个方面入手：意识、资源、监督。这种发展让学校有了更多的方法和有效途径解决存在的问题。这里的First、second、third提示我们三个方面，同时也是一个发展的过程。
信号词五：排列次序
例词：another, the second, the most, the best…
考点：Most important of all, the traditional measures of‘risk’, such as parents’ age and education, or whether they were a single parent, bore little or no relationship to the measures of achievement and language development.(C5, P63, T12判断题)
解析：most important of all强调了最重要的事情，也就是文中比较重要的结论要出炉了。Single parents是题目中的关键词，同样在这一句里出现了，我们可以利用对雅思阅读信号词的敏感度，快速抓住文章的考点，进行局部精读。
信号词六：强调作用
例词：in fact, in essence, in particular, emphasize…
考点：This, in essence, is the problem of modern sociobiology- to discover the degree to which hard-wired genetic programming dictates…(C5, P21, T18信息包含题)
解析：信息包含题考察细节是在那个段落出现，在做此类题目时，要注意信号词与考点的密切相关性，从而迅速找准答案。这里出现了in essence(实质上),起了一定的强调作用，迅速扫读后，发现同时出现了题目关键词sociobiology,破折号后面的介词to是表目的与题目中的the general aim of一致对应。
