雅思写作:表因果关系词汇总结

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:

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 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)

Hours spent on commuting, traffic jams, and fights for parking should diminish, since workers 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)

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 of extreme 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 by a lack of guardrails

So系列(表结果):

1. thus/ therefore / thereby / hence

thus: 表示‘in this/that way’

thereby: by that means, as a result of that

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

hence: 表示 ‘from this/that’

Drinking lots of water is healthy and reducing plastic waste is great for the environment. Hence, trendy reusable water bottles that you can refill yourself are health-promoting, eco-friendly, and green.

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

Cause系列(表结果):

注意这里是result in, 后跟结果,前面提到的result from后面跟的是原因。

3. bring about: to cause to take place 引起,带来(注意使用时更倾向于“带来“这个意思)

The internet technologies that have brought about so much social change were scarcely imaginable just decades before they appeared.

4.spark off 引发、引爆 ,具体指引发比较严重的后果、冲突等(=trigger / activate),或指”点燃“(=inspire)
