C. 初中英语总结.和所有重点及短语 单词 语法
由动词开头构成的短语、词组很多。复习时应分类处理:
一、动词+介词

2.listen to…听……
3.welcome to…欢迎到……

此类短语相当于及物动词,其后必须带宾语,但宾语无论是名词还是代词,都要放在介词之后。
二、动词+副词
“动词+副词”所构成的短语义分为两类:
A.动词(vt.)+副词
1.put on 穿上 2.take off脱下 3.write down记下
此类短语可以带宾语,宾语若是名词,放在副词前后皆可;宾语若是人称代词,只能放在副词的前面。
B.动词(vi)+副词。
1.come on赶快 2.get up起床 3.go home回家
4.come in进来 5.sit down坐下 6.stand up起立
此类短语属于不及物动词,不可以带宾语。

7.1ook young 8.go shopping 9.watch TV/games
10. play games
[介词短语聚焦]
“介词+名词/代词”所构成的短语称为介词短语。现将Unitsl-16常用的介词短语按用法进行归类。
1.in+语言/颜色/衣帽等,表示使用某种语言或穿着……。
2.in + Row/ Team/ Class/ Grade等,表示“在……排/队/班级/年级”等。

7.at work(在工作)/at school(上学)/at home(在家)应注意此类短语中无the。

9.like this/that表示方式,意为“像……这/那样”。
10.of短语表示所属关系。
11.behind/ beside/ near/ under+ 名词等,表示方位、处所。

另外,以下这些短语也必须掌握。如:on ty, after breakfast, at night, at the door, in the middle, in the sky, on one’s bike等。
[重点句型大回放]
1.I think…意为“我认为……”,是对某人或某事的看法或态度的一种句型。其否定式常用I don’t think…,
2.give sth. to sb./ give sb. sth. 意为“把……给……”,动词give之后可接双宾语,可用这两种句型;若指物的宾语是人称代词时,则只能用give it/ them to sb.
3.take sb./ sth. to…意为“把……(送)带到……”,后常接地点,也可接人。
4.One…, the other…/One is…and one is…意为“一个是……;另一个是……”,必须是两者中。
5.Let sb. do sth. 意为“让某人做某事”,人后应用不带to的动词不定式,其否定式为Don’t let sb,do sth.,或Let sb. not do sth. 另外,Let’s 与Let us的含义不完全相同,前者包括听者在内,后者不包括听者在内,
6.help sb. (to) do sth./help sb. with sth.意为“帮助某人做某事”,前者用不定式作宾补,后者用介词短语作宾补,二者可以互换.
7.What about…?/How about…?意为“……怎么样?”是用来询问或征求对方的观点、意见、看法等。about为介词,其后须接名词、代词或V-ing等形式。
8.It’s time to do…/ It’s time for sth. 意为“该做……的时间了”,其中to后须接原形动词,for后可接名词或V-ing形式。

11.show sb. sth. / show sth. to do. 意为“把某物给某人看”,该句型的用法同前面第2点。
12.introce sb. to sb. 意为“把某人介绍给另一人”;introce to sb.则是“向某人作介绍”。

[重温重点句型]
1.So + be/助动词/情态动词+主语.
前面陈述的肯定情况也适于另一人(物)时,常用到这种倒装结构,表示“另一人(物)也如此。”前面陈述的否定情况也适于另一人(物)时,常用“Neither/ Nor + be/助动词/情态动词+主语.”这种倒装结构。
注意:“So+主语+be/助动词/情态动词.”这一句型常用于表示赞同,进一步肯定对方的看法,表示“的确如此。”“是呀。”
neither...nor... , both...and... , either...or... , not only...but also...等句型要遵循相邻原则。
2.Turn right/left at the first/second/…crossing.
这一指路的句型意为“在第一/二/……个十字路口向右/左拐。”相当于Take the first /second/…turning on theright/left.
3.It takes sb.some time to do sth.
此句型表示“干某事花了某人一段时间。”其中的it是形式主语,后面的动词不定式(短语)才是真正的主语.
就等于spent time on sth / spent time in doing sth
4.…think/find + it + adj. + to do sth.
此句型中的it是形式宾语,不可用其它代词替代,形容词作宾语的补足语,后面的动词不定式(短语)才是真正的宾语。
5.What’s wrong with…?
此句型相当于What’s the matter/ trouble with…?后跟某物作宾语时,意为“某物出什么毛病了?”后跟某人作宾语时,意为“某人怎么了?”
6.too…to…
在so…that…复合句中,that后的句子是否定句时,常与简单句too…to…(太……而不能……)进行句型转换。
在so…that…复合句中,that后的句子是肯定句时,常与简单句…enough to…进行句型转换.
7.Sorry to hear that.
全句应为I’m sorry to hear that. 意为“听到此事我很难过(遗憾)。”常用于对别人的不幸表示同情、遗憾之意。

1.弄清词语自身结构用法学生做题时往往仅限于依据词语的中文含义,简单对照。这样就造成了许多中文正确,而英语结构上的错误。如“允许某人干某事”,allow sb to do sth,而不可用做agree sb to do sth.“同意干某事”说allow doing sth.而agree却应为agree to do sth.再如:“希望某人去干某事”expect sb to do sth.不可说为hopesbtodosth.“建议某人去干某事”,说advise sb to do.就不可说是suggest sb to do sth.这是根据动词自身的基本用法而决定的。这些更需要学习中不断积累。
下面是一些常用动词的不同结构用法:
A.以下动词与不定式连用即afford to do sth .afford,agree,appear,arrange,ask,attempt,care,claim,dare,decide,demand,desire,determine,expect,failhappen,
help,
hope,intend,learn,man-age,mean,need,offer,plan,pretend,promise,refuse,seem,used,want,wish

I. 初中英语单词重要还是语法重要
词汇量很重要,语法的话,其实可以用语感代替
要培养语感,最好,最有效率的方法是看原版书籍.
J. 帮我总结初中英语每本书的每个单元的语法。
初一上册!!!
名词的复数形式一般在单数后面加-S或-es (构成方法和发音规则)
s在清辅音后发/s/ 如.desks maps;
在浊辅音、元音后发/z/ 如.jobs workers;
es有两种情况:一般情况下同s,发音是/s , z/
感叹句是用来表达说话者说话时的惊异、喜悦、愤怒、气愤等思想感情的句子。其结构常由感叹词“What(How)+感叹的部分+主语+谓语!”构成。读时一般用降调。主要有以下两大句型:
一、由感叹词what引导的感叹句。
what修饰名词或名词短语,有以下两种形式:
1. What+a(an)+(形容词)+单数可数名词+主语+谓语!如:
What an apple this is!
What a fine day it is!
2. What+(形容词)+可数名词复数或不可数名词+主语+谓语!
What kind women they are!
What nice music it is!
二、由How引导的感叹句。
how用来修饰形容词、副词或动词。其结构是:How+形容词(副词)+主语+谓语!
How hard the worker are working!
How clever the girl is!
How quickly the boy is writing!
注意:当how修饰动词时,动词不跟着感叹词提到主语之前。
How the runner runs!
三、what与how引导的感叹句,一般情况下可以相互转换,转换后意义不变。如:
What an interesting story it is!==How interesting the story is!
what a beautiful bulding it is!==How beautiful the building is!
四、在口语中,感叹句的主语和谓语常常省略。如:
What a nice present!(省略it is)
How disappointed!(省略she is或其它可作本句主、谓的词语)
回答者: 萍mm - 护国法师 十五级 6-20 09:38
感叹句的句型特点及做法:
一、如何快速掌握感叹句?
学会分析五种基本句型的句子成分是快速掌握感叹句的关键,陈述句变感叹句实际上就是句子成分位置的移动。
例1 She is smiling sweetly.
→How sweetly she is smiling!(移动状语)
二、哪些句子成分可能会移动位置?
通过对句子成分的分析我们就可以确定哪个句子成分需要挪动位置,一般说来含有形容词的名词短语、形容词短语和副词短语需要变动位置。位置可能会变动的句子成分:宾语、表语和状语。
例2 Mr Turner told us a funny story.
→What a funny story Mr Turner told us!(移动宾语含有形容词的名词短语)
三、如何确定使用what还是使用how?
当我们做句型变换或选择题时需要自己确定到底是用what还是用how,一般可以这样来确定:位于主语之前的是名词短语时用what,是形容词或副词短语时用how。但这种格式例外: how + adj. + a/ an + N
例3 What a cool bike you are riding!(a cool bike 名词短语)
例 4 How fast he is riding!(fast 副词)
例 5 How cool a bike you are riding!(how + adj. + a/ an +N)
四、如何判断是否使用冠词、使用什么样的冠词?
名词的复数形式和不可数名词之前不使用冠词,以元音音素开头的词语之前用an,以辅音音素开头的词语之前用a。
例6 What beautiful sunshine it is today!(sunshine 不可数名词)
例7 What a useful book this is!(useful 以辅音音素开头)
例8 What an old house that is!(old 以元音音素开头)
五、感叹句有哪几种格式?
简单地说是"两型七式":两种句型是以what开头的句型和以how开头的句型,七种格式是
① what + a + adj. + N+ S +V
② what + an + adj. +N +S +V
③ what + adj. + N(不可数) + S +V
④ what + adj. + N(可数名词复数形式)+ S+V
⑤ how + adj.+ S +V
⑥ how + adv. + S + V
⑦ how + adj. + a/ an + N + S+V
例 What exciting news it is!(what + adj. + N(可数名词复数形式)+ S + V结构)
例9 What good teachers they are!(what + adj. + N(可数名词复数形式)+ S+V结构)
例10 How warmly they are discussing!(how + adv. + S + V结构)
例11 How beautiful a picture it is!(how + adj. + a/ an + N + S + V 结构)
六、以what开头的句型和以how开头的句型怎样进行转换?
这两种句型之间的转换主要是指以下两种情况而言的:
⒈含有"a/ an + adj. + N "结构的句子方法是把形容词单独抽出来放在名词短语的前面和how搭配使用。
⒉名词短语作主语而表语是形容词的句子方法是把主语当作"a/ an + adj. + N"结构的中心名词而用人称代词充当主语。
例12 What an expensive glass he broke! →How expensive a glass he broke!
例13 How beautiful the birds are! →what beautiful birds they are!
(说明:N代表名词,未特别说明者代表可数名词的单数形式,S代表主语,V代表动词)
七、在感叹句中哪些词语常常省略?
常常省略的是充当主语的人称代词和动词be。
例14 What a naughty boy!(省略了he is
