Fcus n 基本用法
be able tdare＆needhave thad better
1. a) be able t 后接动词原形，表示某人做某事的能力，可用于大多数时态。
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。
b) be able t 用于过去时态时，可以表示 “某人过去或当时成功地做了某事”。
2. 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。
① I'm s afraid that I dare nt mve.我吓得一动也不敢动。 ② Dare she ring him at the ffice?她敢打电话到办公室找他吗？
2. b) need 表示 “需要”或 “必须”, 作情态动词时，用于否定句和疑问句中，在肯定句中一般用must, have t, ught t或shuld 代替。needn’t表示“不必；不需要”。
Yu needn’t tell him abut it. He has knwn it.你不必告诉他这件事。他已经知道了。
2. c) dare 和need 常用作实义动词，有时态、人称和数的变化。所不同的是，作实义动词时，在肯定句中，dare+带t的不定式；在否定句和疑问句中，dare+带t/不带t的不定式。
① I dare t swim acrss this river. 我敢游过河去。② He didn't dare (t) say what he thught. 他不敢说出他的想法。③ He des nt dare (t) answer. 他不敢回答。
3. a) have t 的含义与must相似，两者往往可以互换使用，但have t 有各种时态，且强调客观需要，意为 “不得不”。
① It’s dark nw. I have t g hme. 现在天黑了，我必须回家。② I have t leave because f the bad weather. 因为天气不好，我不得不离开了。③ D yu have t wear unifrms at schl? 你在学校必须穿校服吗？
Yu dn’t have t/needn't g if yu dn't want t.如果你不想去，就不必去。
3. b) 否定形式是dn't have t，相当于needn't。
4. had better 后接动词原形，意为 “最好”, 用于现在或将来时，可用于一切人称，没有任何词形变化。 had better 的否定式是在其后加nt,疑问式是把had和nt 提前。
① Yu'd better sit here and have a rest. 你最好坐在这儿休息一下。② She had better nt tell lies any mre. 她最好再也别撒谎了。③ Hadn't the dctr better see him? 医生是不是去看看他比较好？
