西安雅思培训教你三步搞定写作复杂句 

有同学说他对复杂句很是头疼，今天就教大家轻松三步就让你的作文上个档次。
1. Constructing a Complex Sentence 
为了方便理解，这里我们以这个简单句为例：
Cars cause air pollution.
它可以从以下几个方面思考去变复杂句：
why? Why do cars cause air pollution?
where? Where do they cause it?
how? How do they cause it?
when? When do they cause it?
这里我们以why为例：
Cars cause air pollution because their engines emit harmful gas into the 

atmosphere.
Because cars emit harmful gas into the atmosphere, they cause air 

pollution. 也可以放在前面作dependent clause
2. Adding an Opening
给陈述性事实加入一个开头，例如：
It is known to all that cars cause air pollution because their engines 

emit harmful gas into the atmosphere.
也可以用 Some people think that/ It is often considered that 等。
3. Adding a Relative Clause
适当加入定从修饰人，物或者地点。例如：
It is known to all that cars, which remain the most popular means of 

transport in many countries, cause air pollution because their engines 

emit harmful gas into the atmosphere.

以上就是具体思考步骤，各位烤鸭要多加练习才会掌握，更多雅思托福干货内容关注
