雅思英语语法点训练
雅思语法的改变就在于对这些长难句的控制，学会了分数就可以提上去了，就这么简单。下面就是小编给大家带来的雅思英语语法点训练，希望能帮助到大家!
请找出下面句子中的表语从句
1. The question is when he can arrive at the hotel.
分析：
先找句子里的谓语动词，分别是is和arrive。Can不是动词，是情态动词，必须要和谓语动词连用才可以。
一句话有且只有一个谓语动词。这里有两个动词，因此不是简单句，是复杂句，复杂句由一个主句和一个或多个从句组成，有时会有两个或以上主句出现，但是必须要有and这样的连词才可以，这里没有连词，因此只能有一个主句，并且主句必须要出现。
如果句子里有一个动词，这个动词就是主句里的，如果有两个动词，一个一定仍然是主句的，另一个才是从句的。整个句子其实是The question is sth的结构，只不过这里用when he can arrive at the hotel这个从句来代替sth这个表语，因此是表语从句。
Is是系动词，根据“主系表”结构，is前面的成分是主语，后面的成分是表语。
2. The book is not what I need.
分析：
先找句子里的谓语动词，是is和need。一个谓语动词在主句里，另一个在从句里。整个句子其实是The book is sth的结构，只不过这里用what I need这个从句来代替sth这个表语，因此是表语从句。整个句子里有个not，不影响结构，只是多了个否定的意思。
3. That is why she failed to pass the exam.
分析：
先找句子里的谓语动词，是is和failed。一个谓语动词在主句里，另一个在从句里，整个句子其实是That is sth的结构，只不过用why she failed to pass the exam这个从句来代替sth这个表语，因此是表语从句。
4. The argument is whether it rains tomorrow.
分析：
先找句子里的谓语动词，是is和rains。一个谓语动词在主句里，另一个在从句里，整个句子其实是The argument is sth的结构，只不过用whether it rains tomorrow这个从句来代替sth这个表语，因此是表语从句。
表语从句常用引导词
that 在名词性从句中只负责把从句引出来，不在从句里充当成分，这点和在定语从句里的用法不同，定语从句中that充当成分
what 一般不用于定语从句，用在名词性从句里既引导从句，又在从句里充当成分;
which 在名词性从句里含有“哪一个”的意思，通常有一定的选择范围，而在定语从句里则没有意思，只是引导句子和充当句子成分;雅思真题里相关例句很少;
who 在从句里充当成分，指人，不指物;雅思真题里相关例句很少;
how 表示“如何”，可以用来表示程度;
whether 表示“是否”，不管是主语从句，表语从句，宾语从句里都可以使用;
if 用法比较复杂，有多种限制，而且雅思真题里相关例句很少。
