语法讲解
动词不定式
一. 作主语
为避免句子的头重脚轻，常用it作为形式主语，而真正的主语动词不定式后置。
常用句型：It +be+adj./n.+(for/of sb.) to do sth. 做某事对某人来说很……（形容词是nice, kind, right, clever, polite, careless等表示主语品质的形容词。）
It takes sb. some time to do sth. 花费某人多少时间做某事
二. 作宾语
动词agree (同意) offer (提出) intend, plan (打算,计划) demand, ask (要求) promise (答应) help (帮忙) prepare (准备) decide (决定) refuse (拒绝) dare (敢于) choose (选择)
wish,hope,want,expect (希望，想要) fail（不能,忘记） pretend (假装) manage (设法)
determine（决心）常接动词不定式作宾语。
【记忆口诀】同意提出做计划， 要求答应来帮忙。
准备决定遭拒绝， 敢于选择有希望。
不能做到莫假装， 设法做成决心强。
三. 作（后置）定语
常用于“have/has＋sth.＋to do”或“enough＋名词＋to do” “It’s time to do sth.” 等结构中。
四. 动词不定式作状语
主要用来修饰动词，表示目的，结果或原因。为了强调目的，有时可以把动词不定式放在句首，或在不定式前加in order (to) 或so as (to) “为了，目的是”。常用结构有too + adj./adv. + to do sth.等。
五. 作宾语补足语
tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语
构成tell / ask / want / call / invite sb. to do sth. 结构。
【注意】动词不定式作使役动词和感官动词的宾语补足语时应省去to：
“一感(feel) 二听(listen to, hear) 三让let,make,have, 四看look at,see, watch,notice 半帮助help”。
六. 固定句式中动词不定式的用法 常见的形式有：
had better (not) do sth. 最好（不）做…
