语法 Grammar in use

have +名词代替普通动词

第18课的语法中,我们学习了完全动词have的一些用法,知道它既可以表示“具有”、“拥有”,又可以表示 eat, drink, enjoy, take等含义:
I have(got) a new car.
我有辆新汽车。

Have a good time!
祝你(们)玩得开心!

have的另一种用法是 have+名词代替普通动词表示“完成该动作”。类似的动词还有dance, fight, look, rest, ride, talk, sleep, swim, wash等。一般完全动词的用法也适用于have:
Jim and I have just had a long talk.
我和吉姆刚进行过一次长谈。

I must have a wash before lunch.
午饭前我得洗一洗。(情态动词+have)

I had two dances with Lucy.
我和露西跳了两次舞。(可用复数形式)
