对定语从句来说，最重要的就是引导词了，没有引导词就不成句子，所以只有能灵活应用引导词，才是真正的掌握定语从句，引导词的使用也不是那么简单，需要很多的技巧，所以这次小编就为大家带来的是根据修饰词来选引导词的小技巧，一起学起来吧。

根据先行词及先行词前的修饰词来选择。

① This is the most beautiful place that I visited last year.

② This is the place which / that I visited last year.

句①中先行词 place 前有形容词最高级修饰，引导词只能用 that。

句②中先行词 place 前没有形容词最高级修饰，引导词用 which 或 that 均可。

*在下列情况下只能用 that 而不能用 which。

(1)先行词前有序数词或形容词最高级修饰时。

eg. It's the first composition that I have written in English.

(2)先行词前有 any, all, few, little, the only, the right, the very, the last 等修饰时。

eg. You are the last people that  get the chance to attend the party.
