情態助動詞(modal auxiliaries)

多益必考文法--- 英文 的助動詞大致上分為兩類:


一種是「沒有語意,只有文法功能」的助動詞,如do, does, did, have, has等。另一種是「具有語意」的助動詞,也就是情態助動詞,此種助動詞多益文法填空題必考(雖然題數並不會太多),實際上也很常用,非常有必要加以熟 悉,以下我按照各種「語意」做個分類整理。

 

A. 許可 (permission)
may, can, could (can的過去式), must not …
a. You may leave the office as soon as you have finished. (可以…)
b. You can take three books home with you. (可以…)
c. Last summer break we could stay up late on Sundays. (可以…)
