定语从句还有一个重要的细节（看看我的解释）

今天给大家讲一点定语从句常见的用法考点，希望对大家有点帮助。

那就是在定语从句中that和which用法的简明差异。补充一点，定语从句不仅可以修饰它前面的名词和代词，也能修饰前面的一整句话。

第一点就是当定语从句修饰的代词是不定代词时。

我们来具体举例下，不定代词即是all ，few, little, much, every, something, nothing, none等等时，定语从句的引导词只能用that。

举例说明：

This was all (that) I could give to you.The police explained something that can help us.She just gave me some money, not much that can afford what I wanted to buy.There is nothing that you can find to support your plan.其次在非限制性定语从句中用引导词which，不能使用that。这很简单，当定语从句修饰的词或句子和它之间有逗号隔开时，那这个定语从句就是非限定性的。

例如：Thanos was informed that the mind stone was on the earth,which was a coming threat to Vision.

这句话中Thanos was informed that the mind stone was on the earth这句话后面有个逗号，和后面的定语从句隔开了。那后面的定语从句就是非限定性的定语从句。

下一点记住就是“介词+关系代词”引导的定语从句中，只用关系词which，不用that，这一点一定要记住。

例如：

The gate is the one through which we went to see the locals.这句话如果through不提前就可以说成：The gate is the one (which/that) we went through to see the locals.

继续补充一下，我们来看看。

被定语从句修饰的词被不定代词little, few, no, any等，还有被 the only, the very, the same等修饰时。那定语从句的引导词就只能是that了。还有就是被定语从句修饰的词被序数词或形容词最高级修饰时，也只能用that。

例如：The sword seems the onlyweapon that can kill the monster.

I have a little money that can make us survive today.

Did you know the very girl (that) we met that day?

Who was the first/best one that came into the room?

最后我要强调的是：当定语从句修饰的词既有人又有物时；当疑问词which开头的句子出现时，那就只能用that了。

具体举例：

Sam has the money(物）and the people（人）that can help to win this war.

Whichboy belongs to the our team that will fight next morning?

简单讲解，仔细体会。祝大家鼠年好运！
