Unit2 I’ll help to clean up the city parks.◆重点语法一：动词不定式语法全解：动词不定式是动词的一种非谓语形式，是非谓语动词的一种，它没有人称和数的变化，在句中不能作谓语。

1. 动词不定式的构成：动词不定式的基本形式是“to+动词原形”，有时to要省去；动词不定式的否定形式是“not to+动词原形”。

动词不定式没有人称和数的变化，在句子中不能作谓语，但仍保留动词的特点，即可以有自己的宾语和状语。

动词不定式同它的宾语或状语构成动词不定式短语。

● He wanted to sit down. 他想坐下。

● Let me have a look at that letter. 我来看看那封信吧。

● They asked him to sing a pop song at the party. 他们请他在宴会上唱了一首流行歌曲。

● Tell him not to leave alone. 告诉他不要一个人离开。

● I thought I told you not to touch anything！我想我告诉过你什么都不要碰的！2. 动词不定式的用法3. 动词不定式不带to的情况①在固定词组had better之后。

注意：had better do sth.的否定形式是had better not do sth.。

● You had better go home now. 你最好现在回家。

●It’s cold outside. You’d better not go out. 外面很冷，你最好不要出去。

②在使役动词或感官动词后作宾语补足语时，不带to。

这些动词可归纳为：一感（feel）二听（listen to, hear）三让（let, make, have）四看（look at, see, watch, notice）● I made them give me the money back. 我迫使他们把钱还给了我。

【重点语法】动词不定式动词不定式的基本结构为“t+动词原形”。

在句中除不能充当谓语外，其他成分都可充当，如：主语、表语、宾语、状语、宾语补足语、定语等。

在八上已讲过作宾语的用法。

在此主要讲作宾语补足语和状语的用法。

作宾语补足语。

动词不定式作宾语补足语，放在宾语的后面，表示宾语是什么或怎么样。

有td和tbe两种形式。

ThedtradvisedhittaeagdrestIfindEnglishtbevereas提示：在as,tell,ant,uldlie,advise,invite,teah,等动词或短语之后，常接带t的不定式做宾语补足语。

easedhitsingappsngatthepart①动词不定式作宾语补足语时，不定式符号t在使役动词、感官动词的后面时要省略。

但他们变为被动语态时，不定式符号t不能省略。

Thebssadetherersrvertenhursadainthepast=Therersereadetrvertenhursadabthebssinthepast②动词help接不定式做宾语补足语时，不定式符号t 可省略也可不省略。

期中备考-人教版八年级下册unit 2核心考点总结归纳【语法】一、作主语为避免句子头重脚轻，常用it作为形式主语，而真正主语--动词不定式后置。

常用句型：It takes sb. some time to do sth.It +be+adj./n.+(for/of sb.) to do sth.（此句型注意使用介词for和of的区别：用“for”时表示“对于某人来说，做某事是怎样的”，此时的形容词修饰sth；用“of”时表示“某人做某事，某人是怎样的”，此时的形容词修饰sb.）Eg.It took me three hours to finish my homework.It’s difficult for me to finish this alone.It’s kind of you to help me when I was in trouble.二、作宾语动词agree ；offer ；intend，plan ；help；prepare ；decide ；refuse ；choose ；wish，hope，want，expect ；fail ；demand，ask (要求)；promise (答应)；pretend (假装)；dare (敢于)；manage (设法做成)；determine （决心）等后面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。

Eg.I plan to go to Sydney together with my parents next week.三、作（后置）定语“have/has＋sth.＋to do”或“enough＋名＋to do” “It’s time to do sth.” 等结构。

Eg.I have something important to do.It’s time to tidy up your own room.四、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。

八下unit 2 语法归纳■动词短语：动词与其他一些词构成的起动词作用的短语为动词短语。

有的相当于及物动词，有的相当于不及物动词，有的兼有及物和不及物动词的特点。

及物动词可以接宾语，而不及物动词短语不接宾语便可以表达完整的意思。

■动词短语的构成1.动词 + 介词（后接宾语，宾语必须放在介词后面）Eg: I am looking for my glasses. 我正在寻找我的眼镜。

Eg: Don't laugh at others. 不要嘲笑别人。

还有 look at/after/like, take after, agree with, belong to, hear of, get to, learn from, pay for, point at/to/out, talk to/with, think of/about, ask for2.动词 + 副词（三种情况）⑴相当于不及物动词，后面不需要接宾语。

Eg：My money ran out. 我的钱用光了。

Eg: I get up at 6 o'clock every day. 我每天早上6点起床。

还有 fall down, grow up, sit down, stand up, come out,⑵相当于及物动词，当宾语是名词时既可以放在副词的后面，也可以放在动词的前面；当宾语是副词时必须放在Eg: turn on the TV = turn the TV onPut up a tent = put a tent up 支帐篷Eg：Put it up ; think it over⑶既及物也不及物Eg: Don't give up. 不要放弃。

Eg: Don't give up hope. 不要放弃希望。

Eg: When will the plane take off? 飞机什么时候起飞？Eg: Take off your coat. 脱下你的外衣。
