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。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?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?future? 3)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。这一特定的过去时间除有上下文暗示以外,?一般用时间状语来表示。? 2.?结构??was?/?were?(?not?)?+?动词-ing?????? 3.?句式??????? ?肯定式:?

1)?was?not常缩略为wasn’t;?were?not常缩略为weren’t。?

2)?一般过去时与过去进行时用法的比较:?一般过去时表示在过去某个时间发生过的动作或存在的状态,?而过去进行时则表示在过去某一时刻或某一段时间正在进行的动作。?例如:?

David?wrote?a?letter?to?his?friend?last?night.??大卫昨晚给他的朋友写了封信。(信写完了。)?

David?was?writing?a?letter?to?his?friend?last?night.??大卫昨晚一直在给他的朋友写信。(信不一定写完。) 4.过去进行时中的when和while? ?when,?while?区别:?

1)?由when引导的时间状语从句,主句用过去进行时,从句应用一般过去时;?由while引导的时间状语从句,主句用一般过去时,从句应用过去进行时。? When?the?teacher?came?in,?we?were?talking.?

?当此句改变主从句的位置时,则为:??While?we?were?talking,?the?teacher?came?in.??

2)如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导。如:?? They?were?singing?while?we?were?dancing.?
