Step 3　问题探究

1．else的用法

① 没有别的事了，谢谢你。

There_is_nothing_else.Thank_you!

② 你还能看见别的什么人？

Who_else_can_you_see?

③ 快跑，不然我们就迟到了。

Hurry_up，or_else_we_will_be_late!

else的基本含义是“别的、其他的、另外的”等可以用在所有由any­，every­，some­，no­开头及由­body，­one，­thing，­where结尾的不定代词的后面。else用作形容词时常常用来作后置定语，即放在疑问代词who，what，which，when，where，how等后面；else 还常用于固定结构or else，意为“否则、要不然”。
