情态动词
need
既可作情态动词,也可作实义动词。①情态动词:多用于否定句、疑问句,后直接跟动词原形,无人称变化;否定式 needn't = 不必②实义动词:可用于肯定 / 否定 / 疑问,有人称变化(need/needs/needed),结构 need to do sth;否定、疑问需借助 do/does/did
You needn't worry about the result.(情态动词,后直接跟动词原形)He needs to finish the report before Friday.(实义动词,主语三单,后接 to do)
✗ You don't need worry about it.解析:实义动词 need 后必须接带 to 的不定式;正确:You don't need to worry about it.
✗ He need to hand in the paper today.解析:主语 he 为第三人称单数,肯定句中 need 是实义动词,要随人称变化;
正确:He needs to hand in the paper today.
情态动词
had bette
表达 "最好做某事",用于提出劝告或建议,暗含 "不这样做会有不良后果"。①后接动词原形,无人称、数和时态变化,一律用 had(不能用 have)②否定式为 had better not do sth(最好不要做)③疑问句可将 had 提前
You had better start early tomorrow.You'd better not miss the last bus.Had we better leave now?
✗ You have better finish it today.解析:had better 是固定搭配,无论主语人称和时态如何,都必须用 had,不能写成 have better;正确:You had better finish it today.
✗ You had better to stay here.解析:had better 后必须直接跟动词原形,不能加 to;正确:You had better stay here.✗ You hadn't better waste time.解析:had better 的否定式是在 better 后加 not,而不是在 had 后加 not;正确:You had better not waste time.
情态动词
have to
表达客观上 “不得不”;有人称变化 have to /has to;变疑问否定借助助动词 do/does
You have to receive strict training.
❌ Have you to finish the work?解析:have to 的疑问句需要借助助动词;
正确:Do you have to finish the work?

—No, you _________. Students under the age of 16 aren’t allowed to ride electric bicycles.
A.couldn’t B.needn’t C.mustn’t D.can’t
【答案】D
【详解】句意:——妈妈,我能骑电动自行车去上学吗?——不,你不能。16岁以下的学生不允许骑电动自行车。
couldn’t不能(过去式);needn’t不必;mustn’t禁止;can’t不能。根据问句“could I...”是委婉请求许可,回答时应用can’t表示“不可以”,且后句“Students under the age of 16 aren’t allowed to ride electric bicycles”说明是规定上的不允许。
2.—Ms. Li, must we finish the science project today?
—No, you ________. Just make sure it’s done before Friday.
A.mustn’t B.can’t C.needn’t D.shouldn’t
【答案】C
【详解】句意:——李老师,我们今天必须完成科学项目吗?——不,你们不必。只要确保周五之前完成就行。
mustn’t禁止;can’t不能;needn’t不必;shouldn’t不应该。根据答语“No”以及后句“Just make sure it’s done before Friday”可知,今天不是必须完成,只需周五前完成即可,表示“不必、没必要”,应填needn’t。
3.— These purple clay works look so amazing!
— True. But we ________ touch any of them. They break easily.
A.need not B.may not C.mustn’t D.couldn’t
【答案】C
【详解】句意:——这些紫砂作品看起来太神奇了!——没错。但是我们千万不能触摸它们中的任何一件。它们很容易碎。
need not不必;may not可能不/不可以;mustn’t禁止/不能(语气强烈);couldn’t不能(语气委婉)。根据后句“They break easily”可知作品容易破碎,为了保护作品,禁止触摸,mustn’t符合语境。
4.He ________ know the secret. I haven’t told anyone about it.
A.might B.needn’t C.can’t D.mustn’t
【答案】C
【详解】句意:他不可能知道这个秘密。我没告诉任何人关于它的事。
might可能;needn’t不必;can’t不可能;mustn’t禁止。根据后句“I haven’t told anyone about it.”可知我没告诉任何人,推测他不可能知道这个秘密,表示否定推测用 can’t。故选C。
5.—________ we clean the classroom together after the afternoon class?

A.Shall B.Must C.May D.Can
【答案】A
【详解】句意:——下午课后我们一起打扫教室好吗?——好主意!团队合作能让工作变得更轻松更快。
Shall将要/好吗;Must必须;May可以/可能;Can能/可以。根据答语“Good idea!”可知,上句是提出建议。“Shall we...?”是常用句型,用来征求对方意见或提出建议。

A.mustn’t; keep B.needn’t; keep C.needn’t; borrow D.mustn’t; lend
【答案】B
【详解】句意:——这个星期我必须还书吗? ——不,你不需要。你可以保存20天。
考查情态动词和动词辨析。must引导的一般疑问句,否定回答应使用needn’t(不必)。keep保存;borrow借(入);lend借(出)。borrow与lend为非延续性动词,不与时间段连用,keep为延续性动词,可以与时间段连用。故选B。

A.not move B.not to move C.don’t move D.not moving
【答案】A
【详解】句意:这个男人伤得很重。在医生来之前我们最好不要移动他。
考查情态动词的否定。not move 不要移动;not to move 不要移动;don’t move 不要移动;not moving 不要移动。had better (not) do sth. “最好(不)要做某事”。此处had better是情态动词,可直接加not变否定,后跟动词原形。故选A。
