B. 作宾语———动词want, decide, hope, ask, agree, choose, learn, plan, need, teach, prepare…常接动词不定式作宾语。 C. 作（后置）定语———常用于“have/has＋sth.＋to do”或“enough＋名＋to do”“It’s time to do sth.”等结构中。 D. 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)”。 E. 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。 F. 固定句式中动词不定式的用法 常见的形式有：had better (not) do sth./Would you like to do sth. /Why not do sth. /Would you please (not) do sth. 等。 Unit 3 Could you please clean your room Could you please... 句型 （1）请求别人时通常用此句型，也可以说：Can ... ...
