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…

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，后把考点考察的 意思补充完整。

二、对比和转折

例词：however, but, although, nevertheless, on the other hand, by comparison, while

考点：But such projects must be built to higher specifications and with more accountability to local people and their environment than in the past.

雅思培训机构之解题：此题是段落大意配对题，在确定H段段落大意时，段落中间but之后出现的那句话就是解题的关键，根据句子中出现的两个比较级，可以确定答案应该为X The need to raise standards.

三、相似

例词：similarly, in other words, that is, put another way, as …

考点: Thus, we concluded that the blind interpret abstract shapes as sighted people do.(C4, P28, Q40)

解析：题目考的是对文章的总结。因此解题时重点看文章中表示结论的句子，thus这个单词给了我们提示，而句子中的as...do表达的是一个相似的逻辑，因此答案可以确定为B。
