上海牛津版6B语法-情态动词讲解及提升练习

1. 语法特征2

5) 个别情态动词过去式用来表达更加客气, 委婉的语气, 时态性不强；
1
The bag must be Anne’s because it has her name on it.
That man can’t be Prof. Lee. He has gone to Xiamen.
肯定回答：Yes, ...must.
2. must
2）must表示主观义务，意为“应该，“必须”
否定回答：No, ...needn’t / don’t have to.
3如：You mustn’t break the rules/laws.
4
e.g.He said she must go with me.
1）表示客观要求,意为“不得不；必须”
3. have to e.g.Now there’s no bus here, so we had to walk home.
2
e.g.He didn’t have to cancel the plan. 他可能需要打消这个计划。

4. would
e.g. Would you pass me the book?
Would you please post the letter for me? 请帮我寄了这封信好吗?
◆2)
e.g. She asked if I would go with them. 她问我是否愿同他们一起去。

He wouldn’t help me yesterday. 他昨天不愿帮助我。

◆3）常见搭配和句型：
Would you like to do sth…?
Would like/ love to do sth.
表示要求、邀请、希望或询问
would rather… than do…宁愿…而不愿...
表现在的能力，意为“能，会”。

提问：Can .....?
5.can 表现在的请求，允许
回答：Yes, ...can . No, ...can’t. / I’m afraid not.
can’t 和mustn’t 一样，都可表示“不准，不允许”。

表对现在或将来的推测：多用于否定句及疑问句中。

【考点拓展】could的用法：
表过去的能力，作为can的过去式；
could
6. should
表示“应该，应当”，否定结构should not = shouldn’t:
He should work harder. 他应该更加努力。

Crime should be punished. 犯罪应受惩罚。

【考点拓展】should 与ought to:
1) should 强调主观看法，而ought to 强调客观要求，语气稍重。

2) 注意ought to的否定式与疑问式。

① You ought not to do it. 你不应该做此事。

① —Ought he to start now? 他现在该动身了吗？
—Yes, he ought (to) . 是的，该动身了。

① They ought to go now, oughtn’t they?他们现在该走了，对吗？
