17、怀疑等。例如： I must go now. 我现在必须得走了。2）情态动词一般没有人称和数的变化，但是个别情态动词有时态的变化。例如：can的过去式是could。3）情态动词不能单独作谓语，后接动词原形共同做谓语。例如： I can swim. 我会游泳。4)常见的情态动词有：can, may, must, have to, should, would 等。5）情态动词一般不止一个意思，否定式是在情态动词的后面加not, 一般疑问句是将情态动词提到句首。例如：I can t speak French.不会说法语。Can you speak English ？你会说英语吗？ 【用法讲解】一、

19、uld是can的过去式，但是这里并不表示过去时，而是表示委婉语气。拓展： can 和 be able to 的区别（1）情态动词can只有两种时态形式，现在式can和过去式could ,而be able to有多种时态形式。在一般过去时中都表示能够时，两者可以互换。例如： Mary can play the piano. （一般现在时）玛丽会弹钢琴。She could / was able to play the piano when she was five. （一般过去时）她五岁时就会弹琴。She has been able to play it since she was five. （

20、现在完成时）她自从五岁起就会弹琴了。（2）用在过去时中，could经常表示能够做某事，事实上不一定去做，而 was ?were able toW 表示 “过去设法做成了某事” 。在否定句中两者可通用。例如： He could swim across the English Channel.

He might be sick. 他离开学校了，可能是他生病了。4）表示希望、祈求、祝愿may表示希望、祈求、祝愿时，常可译为祝-，但愿May you have a good time. 祝你过得愉快。 May you be happy! 祝你幸福！ May you succeed! 祝你成功！3、 must 的用法1）表必须情态动词must在肯定句中后跟动词原形，表示必须”的含义。例如： You must finish your homework on time. 你必须按时完成作业。 W

He looks so pale. 他肯定是病了。他的脸色那么苍白。The light is on, so he must be at home now. 灯亮着，他现在肯定在家。have to 的用法have to是一个词

25、ow I must study hard. 我知道我必须努力学习。My brother was very ill, so I had to call the doctor in the mid -night. 我弟弟病得厉害， 我只得半 夜里把医生请来。（ 2） must和have to的否定式意义区别很大 ，mustn 表示 不允许和禁止，don t have to表 示 “不必要 ” 。例如： You mustn t park your car here. 不允许在这里停车。 You don t have to go now. 你没必要现在走。（ 3） have to 可以用于多种时态，

26、并且有人称和数的变化； 而 must 一般只表示现在或将来，没有人称和数的变化。例如：I /We/ You/Theymust do something.我（我们/你/你们/他们）必须得做点什么。She has to look after her mother today. 她今天必须照看她妈妈。五、情态动词的问答1）由can弓I起的提问，肯定回答用 can,否定回答用can t例如： Can you open the door? 你能打开门吗？ Yes, I can. 是的， 可以。 / No, I can t. 不，不可以。2）由may引起的提问，肯定回答用 may/can,否定回答用can
