Li Fang went to the hospital.The appointment clerk said that the doctor could see her at 3:30.Li Fang replied that she would not be able to be there at 3:30 because she had a class then.“Shall I put you down for ten to four ” the appointment clerk suggested.Li Fang thought she shouldn’t waste any more time.So she replied,“I think I can make it at ten to four.”
Li Fang went to the class.She asked her teacher,“May/Can I leave at 3:45 today I must/have to have an eye examination.” As expected,the teacher said,“Yes,of course you can.”

语法精讲
情态动词,即表示人的情感和态度的动词,它们本身有一定的词义,但是不能独立作谓语,只能跟动词原形一起构成谓语。情态动词虽然数量不多,但用途广泛。常见的情态动词主要有:can(could),may(might),must,need, shall(should),will(would),dare等。
一、情态动词的基本用法
1.表示“能力(ability)”。表示“能力”时,can用于表示现在或将来的能力,could用于表示过去的能力,be able to可用于各种时态。
(2021·新高考全国Ⅰ卷)The two children could finish cooking a breakfast,which she didn’t expect.
两个孩子做完了早餐,这是她没有想到的。
As a result,humans can perform very complex tasks with their hands.
因此,人类能用手完成非常复杂的任务。
Luckily I was able to catch them and put them back.
幸运的是,我能抓住它们,把它们放回去。
2.表示“可能性(probability)”。can,could,may,might都可以表示可能性,而且这四个词的可能性大小是依次由大到小递减的。
(2021·新高考全国Ⅰ卷) Our aim was to see if we could live,in some way,like real Parisians.
我们的目标是看看我们是否在某种程度上可以活得像真正的巴黎人。

他总是有一种好奇心,想知道什么新的角色或挑战即将到来。
3.表示“建议(suggestion)”。should,ought to,had better都可以表示向别人提出建议。had better语气最弱。
(2021·全国甲卷)One of the ground rules of the swap should be that everyone must try on the clothes before they take them...
交换衣服的基本规则之一应该是,每个人在拿衣服之前都必须试穿……
—Shall I order a taxi for Sarah to go to the airport tonight
—Don’t bother.I’ll drive her there.
——今晚我为莎拉叫一辆出租车去机场好吗
——不用麻烦了。我开车送她去。
In order to get more clicks,you’d better tell me which Chinese culture you westerners prefer.
为了获得更多的点击量,你最好告诉我你们西方人更喜欢哪种中国文化。
4.表示“必要性(necessity)”。need,must,have to,shall等都可以表示“必须,必要”,可以说成是表示命令或奉劝,但must表示主观意愿,need和have to表示客观上必须怎样。mustn’t则表示禁止。
(2021·新高考全国Ⅰ卷)The hot spring at the foot of the mountain is something you must try after the climb.
山脚下的温泉是你爬山之后一定要去尝试的东西。

我喜爱周末,因为在周六和周日我无须早起。
5.表示“请求(request)或许可(permission)”。can,could,may,might,will,would,shall等都可以表示请求或许可。might语气最委婉。
Would you like the opportunity to earn extra cash close to home
你想有机会在家附近赚点外快吗
What about dessert Can I still have ice cream
甜点呢 我还能吃冰激凌吗
Will you please tell me the way to the post office
请你告诉我去邮局的路好吗
二、“情态动词+have done”结构的用法
1.must have done表示对过去发生的事情所作出的合理或很有把握的推测,意为“想必/准是/一定……”,只用于肯定句中,在否定句或疑问句中通常被“can/can’t+have done”代替。
Steam engines were used to pull the carriages and it must have been fairly unpleasant for the passengers,with all the smoke and noise.
蒸汽机被用来拉车厢,周围到处都是烟雾和噪声,对乘客来说一定很不舒服。
2.can have done一般用于疑问句和否定句中,用于表示对过去所发生事情的推测。could have done用于肯定句时,表示“可能已经做过某事”或“本有能力做某事而未做”。
George can’t have gone too far.His coffee is still warm.
乔治不可能走很远,因为他的咖啡还是热的呢。
3.should/ought to have done表示“过去本应该做某事而(实际上)没有做”,含有责备或遗憾的语气;其否定形式表示“某种行为不该发生却发生了”。
You shouldn’t have scolded him for his poor performance.After all,he had done his best.
你本不应该因为他表现不佳而责骂他。毕竟,他已经尽力了。
4.need have done表示“本需要做而实际未做”;needn’t have done表示“本不必做某事而实际做了”。
As it turned out to be a small house party,we needn’t have dressed up so formally.
原来这是一个小型的家庭聚会,我们本来没必要穿得那么正式。
5.may/might have done表示对过去发生的事情的推测,意思是“也许已经做了某事,可能已经做了某事”,多用在肯定句中,用might时表示语气更加不肯定。
You might have read about the news in the papers.
你可能已经在报纸上看过这个消息了。
