语法突破---情态动词、不定式---精讲精练
一、常见情态动词的用法
1.can与be able t（1）相同点：后面都接动词原形；都可表示能力。（2）不同点：can只有一般现在时和一般过去时，即can/culd;可以用于否定句或疑问句中，表示判断或推测；be able t有多种时态变化以及人称和数的变化；表示“过去通过努力做成了某件事”只能用be able t。
2.must与have t（1）must表示说话人的主观意志，意为“必须”,无人称和数的变化。其否定回答通常用dn't have t或needn't,而不用mustn't。如：—Must I finish my hmewrk first?我必须先完成作业吗？—N,yu dn't have t/needn't.不，你不必。
（2）have t 意为“不得不”，往往强调受到外界客观因素的迫使。它可用于多种时态，且有人称和数的变化。如：It is ging t rain.I have t g hme nw.快下雨了，我得回家了。We didn't want t g but we had t.我们并不想去,但是不得不去。
3.以culd开头的，表示委婉请求的疑问句，要用can回答，不能用culd回答。如：—Culd I brrw this bk?我能借这本书吗？—Srry,yu can't.对不起，你不能。
1.I have traveled a lt.I can （会） speak fur needn't （不必） take a car t g there.It's nly five minutes' shuldn't （不应当） drink and drive.It's very dangerus.
4.Anyhw yu must （必须） finish this wrk tday.5.— May/Can （可以） I use yur ruler?—Sure.Here yu are.
二、动词不定式1.动词不定式的形式动词不定式的基本形式为：t+动词原形，其否定形式为：nt t+动词原形。（要注意省略t的动词不定式）
巧记口诀常见的只跟不定式作宾语的动词决定学会有希望（decide,learn,wish,hpe，expect）,同意计划莫假装（agree，plan,pretend）,胆敢拒绝会失败（dare，refuse，fail），
准备设法来帮忙（prepare,manage,help）,提供请求负担起（ffer，beg，affrd），答应安排理应当（prmise,arrange，be suppsed），以上后跟不定式，劝君牢记永不忘。
1.My brther always refuses t let (let) me watch (watch) my favrite TV shw.2.(20·呼和浩特改编)Nw let's welcme ur headmaster t present (present) the prizes t the winners!
