语法:情态动词(Modal Verbs)
1) must
A.表示必须要干的事。如:
We must obey the rules.我们必须遵守规则。
You mustn’t talk like that.你可不能那样说话。
must也可以表达过去情况,主要用于间接引语中。
She said that we must wait a little while.她说我们必须要等一会儿。
B.表示一种推测(只用于肯定句中,语气比may要肯定得多)。
must have则表示对过去情况的推测。例如:
This must be Tom’s room. 这准是Tom的房间。
Jack must have gone there, hasn’t he? / didn’t he?杰克准是去过那儿了,对不对?
C.比较:have to也表示“必须”,但have to更强调客观需要,must着重说明主观看法。如:
We had to be there at 10 o’clock.我们得在10点到那儿。(客观需要)
We must be back before 10 o’clock.我们必须10点前回来。(主观认为)
有时也可互换:
We must / have to leave now.我们得走了。
must和have to的否定式即mustn’t和don’t have to意思完全不同。Mustn’t表示“不作某事”,有禁止的含义;don’t have to表示“不必要(作某事)”,含有“客观上无此必要”的意思。例如:
You mustn’t move someone if the person is badly hurt.如果这人受了重伤,你一定不要动他.
The person isn’t hurt at all. You don’t have to give him first aid.这个人根本就没有受伤,你不必给他进行急救。
2)need need作及物动词,和不定式连用:
need to do sth. 需要干某事
need也可做情态动词,主要用于否定句,即:
needn’t + v.不必干某事 例如:
You need to tell him the reason.你需要告诉他原因。
You needn’t tell him the reason. 你不必告诉他原因。
情态动词need也可用于疑问句,肯定回答对一般must,否定回答时用needn’t.
——Need I come? ——Yes,you must./No,you needn’t.
