定语从句中只用that不用which的多种情况

关系代词指代某物事时，只用that不用which的情况

1. 当先行词是everything, anything, nothing （something 除外,用which或者that均可）, all, none, few, little, some等不定代词时，或当先行词受every, any, all, some, no, little, few, much等词修饰时。如：

2.先行词被序数词或形容词最高级修饰时。

3.先行词被the very，the only，he right，the first，the last等修饰时

4. 先行词前有the same 修饰时

如果表示和先行词是同一物时用the same…that…

This is the same purse that I lost yesterday.

这就是我昨天丢的那个钱夹。

如果表示与先行词同一类或相似的某物，则用the same…as…

This is the same purse as I lost yesterday.

这个钱夹和我昨天丢的那个一样。

5. 先行词是并列结构，既有人又有物时

6. 先行词为数词时

Look at the books on the bookshelf. You can see the two that you bought me for my birthday.

7.避免重复原则，当先行词前面有who, which等疑问代词时

8. 关系代词在定语从句中作表语时，而且通常省略

My hometown is no longer the place that it used to be. 9.关系代词在there be 句型中作主语时,而且常可以省略。如：This is the fastest train (that) there has ever been. 10.……the way that……

(…the reason that… / …the cause that…)

英语语法顺口溜：定语从句只用that情况

口诀：先行不定代，the very/only/first

有高,序，some, all, much, few;

指物人，有了which/who

英语语法顺口溜：定语从句不用that的情况that用法真有趣，两个地方它不去;

逗号后边它不去，介词之后不考虑;
