不定式to-do-的用法备课讲稿
不定式to-do-的用法备课讲稿语法（二）不定式to do的用法一：动词不定式的意义和结构1.不定式的语法意义：（1）在句中做以下成分：主语，宾语，表语，补足语，定语，状语（2）一“无”一“有”：无人称和数的变化有时态和语态的变化（3）仍然保留动词的特点：to—vt+主语；to—vi（+状语）2.结构：肯定式to do ；否定式 not\never to do二：不定式的时态和语态变化时态：与谓语动词相比，动词不定式的时间在谓语动词之前，同时之后进行。
1.一般式：动词不定式表达的动作发生在主句谓语动词之后或同时发生。
2.完成式：动词不定式表达的动作发生在主句谓语动词之前。
eg：I’m sorry to have kept you waiting so long.3．进行式：动词不定式表达的动作发生在主句谓语动词之前。
eg:They seem to be getting along quite well.4.完成进行式：动词不定式表达的动作发生在主句谓语动词之前且进行.语态：动词不定式与主句主语的关系三．句子结构（一）主语：1.不定式作主语，谓语动词用单数（非谓语动词to do ，doing，done只有前两者可以作主语，done相当于形容词）。
2.不定式作主语，常用it形式主语，把 to do 放于句尾。
句式：（1）It is+ 形容词+for sb.to do sth.做某事对于某人来说是怎样的，此处为客观性质的形容词，如：hard，difficult，easy等（2）It is+形容词+of sb. to do sth.意思同上，此处为表示人得性格，本质特征，如：kind，friendly，selfish等Eg：1>It is hard for me to learn math .2>It is kind of you to help me to study.(3)It is +名词+to do 做某事是…Eg:It is our duty to look after the old.(4)It takes/took+主语+时间+to do.花费多长时间做某事Eg：It takes me five hours to finish the homework.(三)宾语1.直接to do 作宾语的动词（主语+vt+todo）:want/plan/ask/agree/afford/arrange(安排)/determine(决定)/decide/expect/fail/hope/happen/manage(设法)offer/object(反对)/promise(许诺)/wait/refuse等2.若to do 作宾语，且后边又跟宾语补足语时，此时用it作形式主语，把to do 放在后面，即构成结构主语+vt+it+宾语补足语+to do (think,consider,make,find,feel)。
