情态动词 (Mdals) 情态动词本身具有一定的词义，不能独立作谓语，必须和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。常用的情态动词包括can (culd), may (might), shall (shuld), will (wuld), dare , need, must, had better, used t, have t, ught t等。 本单元主要涉及的情态动词有be able t, dare, have t, had better, need。下面将对这几个情态动词用法进行讲解。
be able t d sth. 有能力做某事 可用于大多数时态 was/were able t d sth. 过去或当时成功地做了某事 a. I will be able t speak Japanese in anther few mnths.（再过几个月，我 就能讲日语了。） b. They were able t escape frm the building when the fire brke ut. （火灾发生时，他 们设法从那栋建筑里逃了出去。）
be able t与can
二者都表示“能力”，可以互换使用，但也有细微区别：
2) dare & need A. dare 作情态动词时，主要用于否定句、疑 问句和条件从句中，一般不用在肯定句中。 Hw dare yu say I’m unfair?（你怎么敢说我 不公平？） B. need 作情态动词时，用于否定句或疑问句中，在肯定句中一般用must, have t, ught t 或shuld代替。 Yu needn’t cme s early.（你不用这么早来。）
C. dare实义动词，有时态、人称和数的变化。在肯定句中，dare t d sth；在否定句和疑问句中，“t”可以省略。
a. I dare t swim acrss this river. （我敢游过河去。）b. He des nt dare (t) answer. （他不敢回答。）
D. need 作实义动词，有人称和数的变化； sb. need (s) t d sth. 某人需要做某事 sth. need (s) ding/t be dne 某事/物需要被…… a. He needs t earn mre t supprt such a large family. (他需要赚更多的钱来支持这一大家子的生活。) b. This shirt needs washing. = This shirt needs t be washed. (这件衬衫该洗了。)
以need开头的一般疑问句，否定回答用_______,肯定回答用__________;以must开头的一般疑问句，肯定回答用__________,否定回答用________________。
needn’t/dn’t have t
3) have t (不得不) 与must相似，可以互换使用，但have t有各种时态，且强调客观需要，否定式为“dn’t have t”。例如： I have t leave because f the bad weather. （因为天气不好，我不得不离开了。）
have t 与must
4) had better d sth. 最好做某事 用于现在时或将来时，可用于一切人称，没 有任何词形变化。 否定式：had better nt d sth. 疑问式：把had和nt提前a. Yu’d better sit here and have a rest.（你最好 坐在这儿休息一下。）
b. She had better nt tell lies any mre.（她最 好再也别撒谎了。）c. Hadn’t the dctr better see him?（医生是 不是去看看他比较好？）
