五. 动词不定式（to do）的用法1. 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./It takes sb. some time to do sth.2. 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。

3. 作（后置）定语常用于“have/has＋sth.＋to do”或“It‟s time to do sth.”等结构中。

4. 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)”。

5. 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”。

六. Could you please...？句型1. 请求别人时通常用此句型，也可以说Can you...please?情态动词could或can在这里均表示请求，在意思上无区别，但是用could在于其显得更委婉、客气、诚恳。

在日常生活中常使用could you/I...?若在句末加上please，则显得更礼貌。
