四、语法
祈使句
祈使句表示请求、命令、叮嘱、号召等,谓语动词用原形。它的特点是省略了主语you,不需要回答。例如:
Be sure to get here before nine. 千万九点以前到。
Take care not to catch cold.小心别着凉了。
Get out! 滚!
祈使句的否定式多以do not(通常缩写为don’t)引起,也可用never 引起。例如:
Don’t trouble to come over yourself. 你不必费神亲自过来。
Never forget class bitterness! 不忘阶级苦!
Don’t be late next time.下次不要迟到。
祈使句的反意疑问句用will you, 但以let’s开头的祈使句要用shall we。例如:
Let’s go, shall we? 我们走,好吗?
Let me try, will you? 让我试一下,好吗?
Don’t leave, will you?不要离开,好吗?
情态动词should、ought to和must的用法
1. 情态动词should 和ought to作“应该”是同义词。例如:
You should/ought to play with your pet for some time every day.
2. should用于第一人称的疑问句中,表示征询对方的意见,语气较婉转。例如:
What should we do? 我们该怎么办呢?(的用法:)
3. ought to表示责任上、道义上的“应该”。它没有人称和时态的变化,它的语气比should强,常有责备或督促的意思。例如:
They ought to go tomorrow. 他们应该明天走。
4. must的用法:
① must表示“必须”“应该”,表示说话人的命令和要求。例如:
You must do everything carefully. 你必须认真做好每件事。
—Must I go now? —Yes, you must / No, you needn’t.
② must 的否定式有二个:当回答由must引起的问题时,否定回答用needn’t或don’t have to,表示“不必”的意思;当表 示“不允许,禁止”时就用must not。例如:
You must not play balls in the street. 你不许在街上踢球。
③ have to与must意思接近,只是have to着重强调客观需要,must着重说明主观看法。
I must clean the bedroom.(主观想法) I have to clean the bedroom. (客观想法)
④ must be 可以表示推测“一定”“大概”,只用于肯定句。例如:
The bike must be Li Ping’s. 那辆车一定是李平的。
⑤ 表示推测的否定句,“不可能”、“不一定”,用can’t be , 不用mustn’t be。例如:
He can’t be in Shanghai now. 现在他不可能在上海。
