平行英语

：Jack is a student and Mary is a English teacher.（平行结构句子）这句中两个都用be动词。而不要说出成，Jack is a student and Mary teaches English.这样一下用be动词一下又用实意动词，这样就不是平行结构了。

平行结构

Parallel structure

英语写作常见问题之一是句子的平行结构（或称对称结构parallelism)，也就是说当句子或单字结合在一起的时候，必须确保每一个部分都是「同等价值」，也就是必须是同样形式。

平行结构是什么呢?

直接举例，看你是否能发现其中的问题。

1. I like apples, oranges, and going to the zoo.

2. The coach advised that I should eat healthily, exercise regularly, and that joining a gym

would make this easier.

3. Mary is a celebrated author, dancer, and writes great songs.

有发现吗？没关系，我们把其中有问题的地方标出来了，而底线的地方则是平行结构的起始点。

1. I like apples, oranges, and going to the zoo.

2. The coach advised that I should eat healthily, exercise regularly, and that joining a gym

would make this easier.

3. Mary is a celebrated author, dancer, and writes great songs.

知道为什么红字部分错了吗？下面分析句型给你看

·句-"I like noun,noun,and -ing phrase."

·句二"The coach advised that I should:(1) verb;(2) verb;(3) that -ing phrase.

·句三“Mary is a noun,noun,and verb."

这些句子就是不符合平行结构，句中的同等位置的单字没有以同样的文法形式呈现。
