大家在写雅思作文的时候有没有关联词匮乏的烦恼?比如在进行因果论证的时候，总是一个“because”走天下，导致文章看起来过于平淡。其实我们是可以通过使用各种丰富的关联词表达来让作文更出彩的。
一、因果关系的替换可以总结为以下4大类：
基础替换词：比如 since、as、due to 等
从句和句型：比如 which leads to、with 结构等
表达的转述：比如 be responsible for 等
不完全替换：比如 by dint of 等
各位小烤鸭看完后肯定会觉得非常实用，说不定下次写到 because 的时候，还会觉得不替换不舒服呢
不完全替换
1. in this way 这样
例句：In this way, the manager develops a powerful data base of information.
2. as long as 只要
例句：There are few moral limits imposed, so long as what happens is between consenting adults.
3. 一定程度表示“因为”，后面接句子，但是相对非常少用了：
insomuch as / inasmuch as / insomuch that / insofar as / insofar that
例句1：The economic forecast for the coming decade looks promising, inasmuch as we can predict that far in advance.
例句2：The present study was limited in this regard insofar that behavior change was not assessed.
4. 表示“考虑到，鉴于”的意思：
considering / seeing that / given / in consideration of / in view of the fact that
例句1：Given such a dramatic impact on children's lives, one might expect today's high divorce rate to be viewed more widely as a national crisis.
例句2：Seeing that there is often poor visibility, the site chosen as an airport is not appropriate.
5. in order to / in order that 为了
例句：All the parts for this kind of machine must be made of especially strong materials in order that they will not break while in use .

例句：Confidence enables you to win, and by winning you get enjoyment out of the game.
7. not … until 直到…才

8. by dint of 凭借
例句：Trying new and different products by dint of what new and different labels show up on the bar has become second nature to them.
表达的转述
这里的所有表达原意思都不是完全的表达“因为”或者“所以“。但是当两者有前后因果关系时，根据具体的情况可以尝试表达更加自然一些。
使用的时候记得根据原始场景的褒贬意思，以及具体的情况进行调整。有任何不确定的地方，多多参考例句和查词典。
