雅思语法：利用谓语动词抓主干

虽然雅思考试中并没有语法的专题考试，但其实语法的考点是贯穿始终的，为了使学生更好地了解雅思语法的内容，新通外语老师们做了基础的句法整理，希望能为各位烤鸭整理下雅思语法思路。

雅思语法中的基本句型主要是以主谓宾、主系表、主谓三种为主，基本构成就是陈述对象加上陈述内容。其中，最重要的一点是要抓住谓语动词。谓语动词决定了一个句子的骨架结构，分析复杂的长难句时一定要先找谓语。运用这样的技巧，我们发现一些所谓的长难句，其实也是没有那么难的。再来看几个例子。

1. A child hears it spoken from morning till night and， （what is more important）， always in its genuine form， with the right pronunciation， right intonation， right use of words and right structure.

结构：共有2个谓语动词，其中主句的是hears.（what is more）是插入语，而插入语并不重要。所以要先理解插入语两端的内容，再理解插入语。因此，对于插入语，我们的处理方法是：“先读两端，再读中间”。 with后面的right…right…and right…是并列结构。

2.Work， （for most American and Chinese women aged 55 and under）， involves responsibility for a household， a child or children， and a job outside the home as well.

结构：只有一个谓语动词：involves.（for most American and Chinese women aged 55 and under）是插入语。本句的主干为：Work involves responsibility.for后面的内容修饰responsibility，而a household， a child or children， and a job outside the home as well为并列结构。

 3.Still， he could not help thinking that if anything should happen， the nearest person he could contact by radio， （unless there was a ship nearby）， would be on an island 885 miles away.

结构：共有5个谓语动词，主句谓语动词为could not help.that引导think的宾语从句。could contact属于定于从句，省略了引导词，修饰person.unless引导条件状语从句，为插入语。拆分为：

1）Still， he could not help thinking.
2）That if anything should happen.
3）The nearest person would be on … away.
4）he could contact the person.
5）Unless there was a ship nearby.

4.Our knowledge of social systems， （therefore）， （while it is in many ways extremely inaccurate）， is not likely to be seriously overturned by new discoveries.

结构：共有2个谓语动词，其中is not是主句的谓语动词。while引导的让步状语从句，作为插入语，分隔了主语和系动词。拆分为：

1）Our knowledge of social systems is not likely to be seriously overturned by new discoveries.
2）While it is in many ways extremely inaccurate.
