小学英语写作中的平行结构的
在英语语法中，平行（也称为平行结构或平行结构）是在句子的两个或多个部分重复相同的语法形式。
保持平行结构可以帮助你避免语法错误的句子，提高你的写作风格。虽然缺少排比并不总是严格错误的，平行结构的句子更容易阅读，并为你的写作增加平衡感。
并列结构最常用于句子中包含成对或串联的成分。它也适用于学术写作中的标题和提纲。
当两个相似的短语连在一起构成一个句子时，就出现了排比现象。例如:
Tom plays the piano.
Tom plays the violin.
Parallelism = Tom plays the piano and the violin.
这只是一个简单的例子。有许多类型的并行，需要记住的重要一点是，这两种形式必须是相同的。换句话说，如果你有两个并列的动词结构，它们的时态必须相同。例如:
Peter works hard and plays hard. NOT Peter works hard and play hard.
单字平行结构
前面的两个例子都是单字平行结构。下面是单字平行结构的概述:
名词
Jack eats fish and chicken.
Sarah writes poetry and short stories.
动词
Our neighbors have moved and have sold their house.
My sister walks or rides her bike to work.
形容词
he class is not only fun but also helpful.
She is not only strong but also fast.
副词
Peter drives quickly and aggressively.
They work carefully and effectively.
短语平行结构
短语上也可以出现排比现象。这种类型的平行结构可能更难识别，因为句子更复杂。以下是一些例子:
Having fun is as important as working hard.
She advised me to get some sleep and take some time off work.
这是短语平行结构。每种类型的结构都包含一个关于需要考虑的要点/问题的注释。
名词短语
Work is as necessary as play.
Apples are as good for you as oranges.
注意:名词短语在性质上可以是单数或复数，也可以是非人称的(it或they)。
动词短语
Work is as necessary as play.
Apples are as good for you as oranges.
注意:平行结构动词短语中的所有动词都具有相同的词形变化。
副词短语
As soon as I arrive home, I put on my shoes and go for a run.
Before she leaves for work, she usually eats breakfast and has a cup of coffee.
注意:一个副词短语是由多个起副词作用的词组成的。在这种情况下，In less than an hour and In time表示某事将要发生。
动名词短语
He enjoys playing tennis and working out.
They don"t mind waiting and talking while you get ready.
注意:在平行结构中不要把不定式(to do)和动名词(doing)混在一起!
不定式短语
Jackson hopes to visit his parents and see his old friends when he goes home.
She advised me to find some new friends and forget about the event.
注意:在平行结构中不要把不定式(to do)和动名词(doing)混在一起!
分词短语
Discovering her financial losses and not knowing enough about the current market, she decided to stop investing.
Driving through the German countryside and speaking to the people, Mark began to understand the culture better.
注意:这是一个相当复杂的结构。注意逗号是如何放在介绍句子的并列结构分词短语后面的。
使用平行结构
最后，从句也可以用来构成平行结构。在这种情况下，记住你必须使用完整的从句结构(主语+动词+宾语)，而且两个从句的主语是相同的。这使得两个从句中的动词变位保持不变。
