高一英语经典讲义：情态动词(一)
情态动词（一）预热情态动词是英语中唯一一种―为情所困‖的词类，你看它终日处在―情态‖中，反复无常，一会儿凶狠地说must，一会儿又温柔地说might，忽冷忽热，所以我们都得提防着点，不要它今天冷淡，我们误会成热情，不要它热情了，我们又误会成冷淡。
对待情态动词，就要去体会这种―情态‖的感觉。
问世间情为何物，只叫人生死相许。
问英语间情态动词为何物，只叫人蓬头垢面一头雾水。
然天下无难事，只怕有―勤‖人。
●学而时习【情态动词基本花样】情态动词在英文中主要用来表示说话人的看法、态度等。
从用法上来说，它有这样几个特点：1）各个情态动词自身都有一定的词义。
2）情态动词不能在句中独立担当谓语。
3）情态动词在句中不受任何人称、词性、数变化的影响。
4) 情态动词后接的不定式（除ought外）都不带to ，即接动词原形。
英文中的情态动词主要有：can , could, may , might, must, ought, need, dare , dared, have to另外，shall , will , should , would在一定的场合也可用作情态动词。
其中，must表示出于主观意识而必须要做某事；have to却表示由于某种客观原因而不得不做某事。
除此以外，have to自身有时态的变化形式。
●知识点精讲透析●考点一can1.“能够，会”，表示体力或脑力等方面的能力。
例：I am staving to death. I can eat two bowls of noodles now. 我快饿死了，现在我能吃两碗面条。
The classroom can seat thirty students. 这教室能坐三十位学生。
2.“可以”，表示表示请求和允许，常在口语中代替may。
例：Can you tell me the truth? 你可以告诉我真相吗？You can't take the book out of the room. 你不可以将这本书拿出室外。
高考英语情态动词的功能(一)讲义
高中英语情态动词的三大功能（一）情态动词表推测：一、对现在的推测①must :表示“一定”，≥90%的可能性。
只用于肯定句中，不能用于否定和疑问句中。
②should:表示“应该, 总该…….吧”，表示谨慎的推测，常用于服务范围。
有60%--80%的可能性。
例：I think they should be home by now. 我想现在他们总该到家了吧。
③can/could/may/might:表示“可能”，有40%--50%的可能性。
但can一般不能用于肯定句(用于肯定句时表“有时可能”)，may不能用于疑问句。
例：Girls can be very naughty. 女孩子们有时也可能很淘气。
It can be quite cold in Beijing in March. 北京的三月有时也可能相当的冷呀。
例如：他可能是对的。
He can be right. （×）He may be right.（√）他可能是对的？Can he be right? （√）May he be right? （×）④may/might not:表示“可能不”，有20%左右的可能性。
⑤can/could not:表示“不可能”，≥90%的不可能。
例：1、This cake is very sweet. He____________ have put a lot of sugar in it.A. willB. wouldC. mightD. must解析：句意：这个蛋糕很甜，他_____放了许多糖在里面。
根据情态动词表推测排除A和B，因为没有这种用法，剩下C和D，因为前面已经有证据说明蛋糕很甜，那么放糖的可能性就很大，故选D。
例：2、Helen________ go on the trip with us, but she isn' t quite sure yet. （安徽）A. shallB. mustC. mayD. can解析：根据句意：她还没有确定，可以排除B选项，因为shall不能表示推测，故排除。

您可以借20天。
考查情态动词的一般疑问句。
在以must开头的一般疑问句，肯定回答用must；否定回答用need’t或者don’t have to，故排除A和D。
第二空根据“it for 20 days.”可知该空是延续性动词，borrow是短暂性动词，因此排除B。
故选C。
3．In China, all passengers ________ wear protective masks while using public transport. A．should B．need C．can D．must【答案】D【解析】【分析】【详解】句意：在中国，所有乘客在乘坐公共交通工具时必须佩戴防护口罩。
