在雅思写作中因果关系是一种常见的表达技巧，通过因果关系我们可以表达事情之间的联系和自己的态度，但是因果关系也是一种常常让大家感到困惑的一种方式，大家经常对此把握不足，而且经常没有足够的练习来熟练这种技巧。所以下面澳际小编要讲到的就是在雅思阅读中提到的这种因果关系。

　　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 fect、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—fect (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(精品课)中，用了前者就不能用后者的道理。例如：

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

　　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：

　　Because of the increasing number of machine—and as we noted bore, machines magnify human fort—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)

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

　　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)

　　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.

　　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 ,,,

　　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

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

　　So系列(表结果)：

　　1. thus/ therore/ thereby / hence

　　thus：表示‘in this/that way’

　　As a country develops, its cities become the engines of development, thus jobs are available in these areas.

　　therore：表示 ‘for this reason’ /‘because of this or that’

　　In some countries, reduced budgets have led to the elimination of busing systems, therebyincreasing the use of cars and the congestion they create.

　　hence: 表示 ‘from this/that’

　　2.As a result /As a consequence

　　As a result, those people who were indoors had much lighter skin, which means that whiter skin is now associated with having a higher status than dark skin.

　　As a consequence, environmental health must address the societal and environmental factors that increase the likelihood of exposure and disease.

　　3.consequently/ accordingly

　　Consequently更偏重因果逻辑;accordingly更偏重后续解决

　　Water pollution affects drinking water, rivers, lakes and oceans all over the world. This consequently harms human health and the natural environment.

　　Cause系列(表结果)：
