雅思写作中因果关系表达的干货总结

　　雅思写作考试中，因果关系的表达常常难倒很多考生，本文中，精选雅思常考话题，将雅思写作中因果关系表达的干货做了详尽整理，希望对大家备考雅思有帮助。

　　雅思大作文中有一类题目是因果关系类，具体包括三小类：cause and effect、cause and solution、problem and solution。这三小类问题也可以穿起来，即针对某个topic的cause—effect (即problem) – solution。

　　无论哪种题目，写明因果关系很重要。关于因果关系的表达同学们都很熟悉，无非是BS(because / so)，而且大家也一定很清楚的知道BS在英语中，用了前者就不能用后者的道理。例如：

　　ü Because further education has become more accessible for a wider range of people, an increasing number of people have degrees.

　　ü Further education has become more accessible for a wider range of people, so an increasing number of people have degrees.

　　但是除了BS之外，还有很多其它表示因果关系的表达，具体如下：

　　Because系列(表原因)：

　　1. because of : because后接的是一个句子(主谓宾);because of 后一般直接跟名词。例如：

　　ü Because of the increasing number of machine—and as we noted before, machines magnify human effort—then anyone using a machine can get a higher wage than anyone not using a machine.

　　2. as / since(除了“因为“外，还有”自从”的意思，使用时要注意避免歧义)

　　ü Hours spent on commuting, traffic jams, and fights for parking should diminish, sinceworkers make fewer journeys or work staggered hours.

　　ü Unfortunately, as the number of people living in the city increases, so do the different problems associated with population growth. (注意此句中的so不表示“所以”，而是“…也…”的意思)

　　3. thanks to(positive situations通常适用于结果好的时候)

　　ü Thanks to new technology, it's easier than ever to work remotely.

　　due to (negative situations通常使用与结果不好的时候)

　　owing to / attributable to /on account of.

　　ü Due to /… / On account ofextreme weather conditions, damage to property occurs.

　　4. 当原因需要的表达较多时，我们还可以把以上表达改写为原因状语从句，使用thanks to the fact that / due to the fact that /owing to the fact that或者on the grounds that ,,,

　　ü Will we live longer merely due to the fact that / on the grounds that technology, if implemented properly, will take stress away from our lives

　　5. caused by /result from也表原因

　　ü Many car accidents were resulted from / caused bya lack of guardrails
