Unit 2 I'll help clean up the city parks动词不定式A. 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.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。

常用结构有too + adj./adv. + to do sth.等。

Unit 3 Could you please clean your roomCould 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在于其上显得更委婉、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。
Could you help me find my book,please?你能帮我找到我的书吗？（2）对could you/I...?的问句作出肯定回答，常用“sure/certainly/of course”等；如果作否定回答，常用“sorry或oh,please don’t”。
一般不用no开头，用no显得语气生硬、不礼貌。
（3）表示请求的句式：Would you like to do...? Would you mind doing...? Let’s do.... Shall I/we do...?Please do...(祈使句前加please)提示：could you please...与could I Please...两种问句，前者是请求别人帮忙的句式，后者是有礼貌地向别人请求允许的交际用语。
试比较：Could you please help me?请你帮我一下好吗？Could I please invite my friends to my birthday party,Mom? 妈妈，我能邀请我的朋友参加我的生日聚会吗？Unit 4 Why don't you talk to your parents?1.提建议向别人发出邀请，请求，建议，或征求某人的意见的其他表达方式：How /what about doing sth.?（about是个介词，可跟名词或动名词）“…怎么样？”You’d better (not) do something.“你最好（不）做某事”Would you like sth …?:“你想要某物Let?s do sth…?What should I do …? ( should表示请求、征询对方意见)2.学会谈论问题和学会用why don't you…提建议向别人发出邀请，请求，建议，或征求某人的意见的表达方式：Why don?t you do something? =Why not do something? 你为什么不做某事呢？来表示请求、征询对方意见３．until, so that ,although引导的状语从句：1)until：在带有till或until引导的时间状语从句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。
如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。
Don?t get off until the bus stops.2）so that引导目的状语从句（为了，以便）例如：He studies hard so that he could work better in the future3）although的用法意思相当于though（尽管，虽然），引导让步状语从句。
引导的从句不能与并列连词but，and， so 等连用，但可以和yet， still等词连用。
例如：Although he was tired, he went on working.尽管他很累，但是他继续工作。
Unit 5 What were you doing when the rainstorm came？过去进行时1. 基本概念：过去进行时表示在过去某一时刻或一段时间内正在进行的动作。
