九年级英语复习---语法讲解(1-7单元)
Unit1
By是个很常用的介词(有时也用作副词),在初中英语中的用法有以下几种: 1.意为“在……旁”、“靠近”。如: Some are singing and dancing under a big tree . Some are drawing by the lake. 有的在大树下唱歌跳舞,有的在湖边画画儿。 2.意为“不迟于”、“到……时为止”。如: Your son will be all right by supper time. 你的儿子在晚饭前会好的。 How many English songs had you learned by the end of last term? 到上个学期末你们已经学了多少首英语歌曲? 3.表示方法、手段,可译作“靠”、“用”、“凭借”、“通过”、“乘坐”等。如: The monkey was hanging from the tree by his tail and laughing.
猴子用尾巴吊在树上哈哈大笑。 The boy’s father was so thankful that he taught Edison how to send messages by railway telegraph.
孩子的父亲是那么的感激,于是他教爱迪生怎样通过铁路电报来传达信息。 4.表示“逐个”、“逐批”的意思。如: One by one they went past the table in the dark.
他们一个一个得在黑暗中经过这张桌子。5.表示“根据”、“按照”的意思。如:What time is it by your watch? 你的表几点了? 6.和take , hold等动词连用,说明接触身体的某一部分。如: I took him by the hand. 我拉住了它的手。 7.用于被动句中,表示行为主体,常译作“被”、“由”等。如: English is spoken by many people. 英语被许多人所说。(即“许多人讲英语。”) 8.组成其它短语。 1) by the way : 意为“顺便说”、“顺便问一下”,常做插入语。如: By the way , where’s Li Ping , do you know?
顺便问一下,李平在哪儿。你知道吗? 2) by oneself : 意为“单独”、“自行”。如: I can’t leave her by herself. 我不能把她单独留下。 3) by and by : 意为“不久以后”、“不一会儿”。如: But by and by , more and more people began to study English. 但是不久以后,越来越多的人开始学英语了。
二、动名词的构成动词后加动名词doing,相当于名词,在句子中可以做主语、宾语、表语定语等。1)★作主语(这种用法常考)
Fighting broke out between the South and the North.南方与北方开战了。2)作宾语Would you mind turning down your radio a little, please?
请问你介意调小一点收音机的音量吗?3)作表语Babysister’s job is washing,cooking and taking care of the children。保姆的工作是洗衣服,作饭和照看孩子。
Unit2
used to 的用法:(1)肯定句:used这个词没有人称的变化,to后面接动词原形。
否定句是didn’t use to….
When I was a child, I didn’t use to like apples.当我还是孩子的时候我不喜欢苹果.
疑问形式是Did you use to…?Where did you use to live before you came here?当你来这儿之前你住哪儿?
(2)含有used to 的句子的反意疑问句不要usedn’t + 主语,而用didn’t + 主语。He used to smoke, didn’t he? 他过去常常吸烟,是吗?Yes, he did./ No, he didn’t. 是的,他吸。/ 不,他不吸。
(3)used to 表示过去的习惯动作, 而不是现在的。I am used to the weather here. 我已经习惯于这里的天气了。He is used to hard work. 他习惯于艰苦的工作。
(4)used to 可以和be, have 以及其他状态动词连用,描写过去的状态。 I used to be a waiter, but now I’m a taxi-driver.我过去是一个服务员,但现在我是出租车司机。
★ 本单元的许多运用used to 的句子属于描述过去的状态。Mario used to be short.马力奥过去总是很矮。Amy used to be outgoing.爱米过去性格外向。Tina used to have long and straight hair.蒂娜过去有一头直的长头发。He used to wear black shoes. 他过去常穿黑鞋。
Unit3
本单元重点讲到了被动语态的用法英语动词的被动语态由助动词be加及物动词的过去分词构成。助动词be有时态,人称和数的变化,其变化规则与连系动词be完全一样。
一、被动语态的句式变化: 以一般现在时和动词invite为例,列表说明被动语态的句式变化:
二、各种时态的被动语态结构总结如下: 被动语态的时态是由be的时态决定的,be是什么时态,全句就是什么时态,be动词后面的过去分词不变。一般现在时的被动语态为:主+am / is / are (not)+过去分词一般过去时的被动语态为:主+was / were +过去分词
例如:我们学过的was / were born 生于,就是一个被动语态.born是个过去分词(bear)-When were you born ? -I was born in 1989. 现在进行时被动语态的构成为: 主语+is / am / are + being +过去分词
现在完成时被动语态的构成为: 主语+have / has +been +过去分词
情态动词的被动语态: 情态动词+be+过去分词
一般将来时的被动语态: 主语+will +be +过去分词
过去将来时的被动语态: 主语+would / should + be +过去分词
过去进行时的被动语态: 主语+was / were + being +过去分词
过去完成时的被动语态: 主语+had + been +过去分词
三、被动语态的用法:(1)不知道或没有必要说明动作的执行者是谁,不用by+动作执行者短语 Football is played widely all over the world. 全世界都广泛地踢足球。
(2)强调动作的承受者,这时应用by短语。The bank was robbed yesterday afternoon. 昨天下午这家银行遭到抢劫。
(3)作客观说明时,常采用一种被动语态句型It is reported that about twenty children have died of flu in the USA.
据报道美国大约二十名儿童死于流感。
四、主动语态的句子变为被动语态的方法是:(1)把原句中的宾语变为主语(2)动词改为被动形式,即be+过去分词(3)原来的主语,如果需要的话,放在by后面,如果没必要,可省略。请看下表:
主动语态 被动语态
They make trains in Zhuzhou. They use this key for locking the classroom door.Many people speak English.He wrote a letter.They are building a road. Trains are made in Zhuzhou.This key is used for locking the classroom door(by them).English is spoken by many people.A letter was written by him.A road is being built (by them).
Unit4
虚拟语气:如果我们所说的不是事实,也不是要求、命令、劝告等,而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气
注意:条件句分两种,真实条件句和虚拟条件句。只有在虚拟(非真实)条件句中,才用虚拟语气,而在真实条件句中,要用陈述语气。
请比较:
(1)If it is sunny tomorrow , we’ll go to the zoo.
如果明天天气好,我们将会去公园。在这句话中,明天天气好是完全有可能实现的,并非虚拟、幻想,因此是真实条件句。在本句中,适用“主将从现。”
(2)If I were you , I would go at once.
(如果我是你的话,我立刻就走。)在这句话中,条件句,“如果我是你”,但事实上,我不可能成为你,这只是假设的情况,没有实现的可能。当条件实现的可能性很小,甚至可以说没有时,就需要用虚拟语气来表示,动词发生了变化。
也就是说虚拟语气表示和现实的事实相反时,从句用一般过时。
主句用 “should/would/could/ might +动词原形。
1.If I had time, I would go for a walk.
2.If I were invited, I would go to the dinner party.
3.If I won a million dollars in the lottery, I would put it in the bank.
知识点2. He doesn’t know if he should bring a present.
此处if表示“是否”,引导宾语从句。Should此处表示“应该”。不是虚拟语气。
E.g.1. I don’t know if I should go to the party.
2.If I have enough money, I will go to Hainan .
知识点3.If I were you , I’d wear a shirt and tie.
if 引导的条件状语从句表示与现在事实相反的虚拟语气时,be动词只能用were,而不能用was。
E.g. If he were here, he would not agree with you .
知识点4. I don’t have a present. What if everyone else brings a present?
What if… “如果……怎么办?”相当于 what would happen if…
E.g. What shall I do if it snows?
知识点5.Well, dogs can be a lot of trouble.
Trouble 麻烦事 ,名词
常用搭配 :get (sb)into trouble get out of trouble what’s the trouble
“if”引导的条件句。

在选择引导定语从句的关系代词时,有如下要点:
1 由于关系代词在主句与从句间既起到联系作用,又在从句中充当一个成分,因此, 要正确判断关系代词在从句中的功能,如作主语还是宾语等。
2 当先行词指人时,关系代词可用who(做主语,宾语),that(做主语,宾语),whom(作宾语),whose(作定语)
3 当先行词指物时,关系代词可用that(做主语,宾语),which(做主语,宾语)
4 再定语从句中,作宾语的关系代词长可省略,但在介词后面的关系代词不能省略。指人时,介词后只用whom,指物时,介词后只用which。
5 在非限制性定语从句中,指人时,只用who,指物时,只用which。
1.定语从句中that与who、which的区别
2.定语从句中关系词的省略
典型例题
1. The first job ________I found was to be a cleaner.
A. where B. why C. which D. that
解析:指事物的先行词前有序数词修饰时,只能用关系代词that。故本题的正确答案是D。
2. I don’t think history is as interesting as English.(改为同义词)
I think history is ___________ interesting _________ English.
解析:答案是:less; than。意思是“我认为历史不如英语有趣”。
3. The woman who is wearing the hat is my mother.(改为同义句)
The woman ________ the hat is my mother.
解析:读题后可知:上句含义是“戴帽子的那个妇女旭我的妈妈”,对应下句,可知空格处应填“戴”,故正确答案是in。
选择填空
1. The poor boy ________ lost both his parents last year is called Mike.
A.which B.what C.who D./
2. The bridge ________ has been there for nearly fifty years still looks nice.
A.which B.what C./ D.who
3. I’m one of the students _______well in English in my class.
A.who does B.who do C.which does D.who did
4. Is this factory ________ some foreign friends visited last Friday?

九年级英语复习---语法讲解(Units8-15)
Unit8
1、短语动词小结
常见短语动词结构有下面几种:
1.动词+副词 如:give up 放弃 turn off 关掉 stay up 熬夜
这种结构有时相当于及物动词,如果其宾语是代词,就必须放在动词和副词之间,如果是名词,则既可插在动词和副词之间,也可放 在短语动词后。
2. 动词+介词 如:listen of 听 look at 看 belong to 属于
这种结构相当于及物动词,后面跟宾语。
3. 动词+副词+介词 如:come up with 提出,想出 run out of 用完,耗尽
4. 动词+名词(介词) 如:take part in参加 catch hold of 抓住
2、倒装句
not only … but (also) … 不但… 而且… 用来连接两个并列的成分
(1)引导以 not only …but (also)… 开头的句子往往引起部分倒装。
因此 ⑴Not only do I feel good but (also)…. 是倒装句。也是说得要
把前面的句子中的助动词或者是情态动词放在主语的前面。如:
①Not only can I do it but (also) I can do best. 我不仅能做到而且做得最好。
⑵Not only…but (also)… 接两主语时,谓语动词随后面的主语人称和数的变化 也就是就近原则 如:
①Not only Lily but (also) you like cat. 不仅莉莉而且你也喜欢猫。
②Not only you but (also) Lily likes cat. 不仅你而且莉莉喜欢猫。
常见的就近原则的结构有:
Neither… nor…即不…也不… (两者都不)
Neither you nor I like him. 我和你都不喜欢他。
Either… or… 不是…就是… (两者中的一个)
Either Lily or you are a student.
Not only …but (also)…

‘叁’ 初三英语重要知识点有哪些
动词不定式一. 定义:
动词不定式是非谓语动词的一种,它没有人称和数的变化,在句子中不能独立作谓语,但它仍保持动词的特点,既可以有自己的宾语和状语。同时动词不定式又具有名词、形容词、副词的特征,在句中可以作主语、表语、宾语、宾语补足语、定语和状语
二. 动词不定式的构成:to+动词原形
三. 动词不定式作宾语后面能接不定式作宾语的动词有:agree, ask, choose, decide, forget, hope, learn, want, wish, would like等。
We hope to get there before dark. The girl decided to do it herself.
动词不定式作宾语的注意事项(2点)
1. 有些动词既可跟不定式作宾语,也可跟动名词作宾语,但含义不同:
remember to do 记住要做某事 remember doing 记得曾经做过某事
forget to do忘记要做某事 forget doing 忘记曾经做过某事
stop to do 停下来去做某事 stop doing 停止做某事
go on to do 继续做另一件事 go on doing 继续做原来在做的事
I remember seeing you somewhere before
Please remember to turn off the light when you leave.
2. 不定式作宾语时,如带有宾语补足语,则要把不定式放到后面,用it作形式宾语,构成“主语+动词+it+宾补(形容词、名词)+不定式”结构。
如:He found it very difficult to get to sleep.
四. 动词不定式作宾语补足语 1. 后面能接to不定式作宾语补足语的动词有:ask, order, teach, tell, want, wish, help等。
The teacher told us to do Exercise 1.
I want both of you to go. We helped her (to) repair her bike.
2. 使役动词let, have, make及感官动词see, watch, notice, hear, feel等要以不带to的不定式作宾补。
Let’s have a rest. I saw him come in.
感官动词后既可跟不带to的不定式作宾补,也可跟v-ing作宾补,前者表示动作的全部过程已结束;后者表示动作正在进行。
I saw him come downstairs.我看见他下了楼。(说明他下楼了这件事)
I saw him coming downstairs.我看见他在下楼。(说明他下楼时的情景)
五. 动词不定式作状语
Later he left home to work in different cities.
He went to see a football match.
In order to catch the other students, I must work hard.
六. 动词不定式作定语一般放在所修饰的词的后面。
I need something to eat. Do you have something to read?
Tom was so excited that he had no word to say.
He is really a fool only to eat.
The man to stand here just now is our English teacher.
The doctor had no way to save the patient.
注意:(1)作定语的不定式是由及物动词组成,被修饰的名词或代词与不定式之间存在方位或方式关系需要有介词。
I am looking for a room to live in(方位关系)
We have many things to do experiments with. (方式关系)
(2)作定语的不定式是由“be + adj + prep”构成的动词短语。
Here there isn’t any book for me to be interested in.
We have done many things to proud of.
七. 动词不定式作主语To give is better than to receive.
To reach there on foot is impossible.
动词不定式作主语时,可以用it 代替,把实际主语不定式放在后面。
It’s better to give than to receive.
It’s impossible to reach there on foot.
It’s + adj + for sb. to do sth.
It’s not difficult for me to study English well.
It’s easy for him to work out this math problem.
在这个句型中,如果形容词与不定式的逻辑主语关系密切,并且形容词用来说明逻辑主语性质、品质、特点等,由of引出逻辑主语。这类形容词主要有nice, kind, good, wrong, right等。
八. 动词不定式和疑问词连用
动词不定式可以和疑问词what, which, how, where, when连用,构成不定式短语,可以作主语、宾语、表语、宾语补足语等。
How to do is still a question. Have you decided when to leave?
九. 动词不定式的否定形式
动词不定式的否定式是在to前加not;不带to的不定式则在动词前加not. 如:
Zhang Ming asked me not to stay at home all day.
My mother let me not do it by myself.
被动语态两种语态:主动语态和被动语态
主动语态(The Active Voice)表示主语是动作的执行者。
被动语态(The Passive Voice)表示主语是动作的承受者。
构成:承受者+助动词be+及物动词的过去分词+by+执行者
一般现在时:承受者+助动词am / is/are +及物动词的过去分词+by+执行者
一般过去时:承受者+助动词was / were +及物动词的过去分词+by+执行者
承受者+助动词shall / will be+及物动词的过去分词+by+执行者
承受者+助动词 have/ has been+及物动词的过去分词+by+执行者
承受者+ can /may/must/should +be+及物动词的过去分词+by+执行者
被动语态用法:
1)当我们不知道动作的执行者是谁,或者没有必要指出动作的执行者时,需用被动语态。
2)当我们需要强调动作的承受者时,常用被动语态。
3)如果需要说出动作的执行者, 用by引导出动作的执行者。
主动语态变为被动语态时,其谓语动词的时态要与原句时态保持一致,其谓语动词的数要与新主语保持一致。
主动语态变为被动语态时有以下几种情况:
1)主语+谓语动词+宾语 将主动语态的宾语变为被动语态的主语。
(主动)We bought a book yesterday.
(被动)The book was bought yesterday.
2)主语+谓语动词+间接宾语+直接宾语
将主动语态中一个宾语变为被动语态的主语。多数情况下将间接宾语变为主语。如果直接宾语变为主语时,间接宾语前要加介词to / for。
(主动)He showed me a book yesterday.
(被动)I was showed a book yesterday.
(被动)The book was showed to me yesterday.
3)主语+谓语动词+复合宾语
含有一个由宾语加宾语补足语构成的复合宾语,变为被动语态时,将主动语态的宾语变为被动语态的主语,宾语补足语保留不变,成为主语补足语。
(主动)I found him a good pupil. (宾语补足语)
(被动)He was found a good pupil. (主语补足语)
4)短语动词变为被动语态
有些短语动词相当于一个及物动词,其后可以接宾语,因此它们也有被动语态,但短语动词是不可分割的整体,变为被动语态时不可去掉其后面的介词或副词。
(主动)We should look after the patients very well.
(被动)The patients should be looked after very well by us.
5)宾语从句变为被动语态
若主动语态中是宾语从句,变为被动语态时常用it作形式主语,而把真正的主语放在后面。 It’s said that he passed the exam.
被动语态应注意的几个特殊问题:
(1)不及物动词带介词和介词宾语,在变为被动语态时,仍然要带上介词。
(主动)The students in class listen to the teacher carefully.
(被动)The teacher is listened to carefully by the students in class.(2)当动词带有复合宾语时,并且宾补是省去“to”的动词不定式时,在被动语态中应加上“to”。
(主动)They make do all the work.
(被动)We were made to do all the work.
(主动)We often hear her sing English songs.
(被动)She is often heard to sing English songs.
(主动)I see him walk to school.
(被动)He is seen to walk to school.

返回动词的时态目录
11.10 比较一般过去时与现在完成时
1)一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。
2)一般过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。
一般过去时的时间状语:yesterday, last week,…ago, in1980, in October, just now等,皆为具体的时间状语。
现在完成时的时间状语:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等,皆不确定的时间状语。
共同的时间状语:this morning, tonight, this April, now, already, recently, lately 等。
3)现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know.。
一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。例如:
I saw this film yesterday. (强调看的动作发生过了)
I have seen this film. (强调对现在的影响,电影的内容已经知道了)
Why did you get up so early? (强调起床的动作已发生过了)
Who hasn't handed in his paper? (强调有卷子未交,疑为不公平竞争)

句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。
(错)Tom has written a letter to his parents last night.
(对)Tom wrote a letter to his parents last night.
返回动词的时态目录
11.11 用于现在完成时的句型
1)It is the first / second time.... that…结构中的从句部分,用现在完成时。例如:
It is the first time that I have visited the city. 这是我第一次访问这城市。
This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。
注意:It was the third time that the boy had been late.
2)This is +形容词最高级+that…结构,that 从句要用现在完成时。例如:
This is the best film that I've (ever) seen. 这是我看过的最好的电影。
典型例题
(1) ---Do you know our town at all?
---No, this is the first time I ___ here.
A. was B. have been C. came D. am coming
答案B. This is the first time 后面所加从句应为现在完成时,故选B。
(2) ---Have you ____ been to our town before?
---No, it's the first time I ___ here.
A. even, come B. even, have come C. ever, come D. ever, have come
答案D. ever意为曾经或无论何时,反意词为never,此两词常用于完成时。
注意:非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。
(错)I have received his letter for a month.
(对)I haven't received his letter for almost a month.
返回动词的时态目录
11.12 比较since和for
Since 用来说明动作起始时间,for用来说明动作延续时间长度。例如:
I have lived here for more than twenty years.我住在这儿二十多年了。
I have lived here since I was born. 我从出生起就住在这儿了。
注意:并非有for 作为时间状语的句子都用现在完成时。
I worked here for more than twenty years. (我现在已不在这里工作。)
I have worked here for many years.(现在我仍在这里工作。)
注意:用句型转换的方法,很容易排除非延续动词在有for/since结构的完成时中的误用。
1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
显然,第二句不对,它应改为 Harry got married six years ago. 或 Harry has been married for six years.

11.13 since的四种用法
1) since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。例如:
I have been here since 1989. 1989起,我一直在这儿。

返回动词的时态目录
11.14 延续动词与瞬间动词
1) 用于完成时的区别
延续动词表示经验、经历; 瞬间动词表示行为的结果,不能与表示段的时间状语连用。例如:
He has completed the work. 他已完成了那项工作。 (表结果)
I've known him since then. 我从那时起就认识他了。(表经历)
2) 用于till / until从句的差异
延续动词用于肯定句,表示"做……直到……" 瞬间动词用于否定句,表示"到……,才……"。例如:
He didn't come back until ten o'clock. 他到10 点才回来。
He slept until ten o'clock. 他一直睡到10点。
典型例题
1. You don't need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B. 首先本题后句强调对现在的影响,我知道她的模样,你不用描述。再次,several times告知为反复发生的动作,因此用现在完成时。
2. ---I'm sorry to keep you waiting.
---Oh, not at all. I ___ here only a few minutes.
A. have been B. had been C. was D. will be
答案A. 等待的动作由过去开始,持续到现在,应用现在完成时。
返回动词的时态目录
11.15 过去完成时
1) 概念:表示过去的过去
----|----------|--------|----> 其构成是had +过去分词构成。
那时以前 那时 现在
2) 用法
a. 在told, said, knew, heard, thought等动词后的宾语从句。例如:
She said (that)she had never been to Paris. 她告诉我她曾去过巴黎。
b. 状语从句
在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。例如:
When the police arrived, the thieves had run away. 警察到达时,小偷们早就跑了。
c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"。例如:
We had hoped that you would come, but you didn't. 那时我们希望你能来,但是你没有来。
3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。例如:
He said that he had learned some English before. 他说过他以前学过一些英语。
By the time he was twelve, Edison had began to make a living by himself. 到了十二岁那年,爱迪生开始自己谋生。
Tom was disappointed that most of the guests had left when he arrived at the party.
汤姆失望了,因为他到达晚会时,大部分客人已经走了。
典型例题
The students ___ busily when Miss Brown went to get a book she ___ in the office.
A. had written, left B,were writing, has left C. had written, had left D. were writing, had left
答案D. "把书忘在办公室"发生在"去取书"这一过去的动作之前,因此"忘了书"这一动作发生在过去的过去,用过去完成时。句中when表示的是时间的一点,表示在"同学们正忙于……"这一背景下,when所引导的动作发生。因此前一句应用过去进行时。
注意: had hardly… when 还没等…… 就……。例如:
I had hardly opened the door when I he hit me. 我刚打开门,他就打了我。
had no sooner…than 刚…… 就……。例如:
He had no sooner bought the car than he sold it. 他刚买了这辆车,转眼又卖了。

11.16 用一般过去时代替过去完成时

When she saw the mouse,she screamed. 她看到老鼠,就叫了起来。
My aunt gave me a hat and I lost it. 姑妈给了我一顶帽子,我把它丢了。
2 ) 两个动作相继发生,可用一般过去时;如第一个动作需要若干时间完成,用过去完成时。例如:
When I heard the news, I was very excited.
3) 叙述历史事实,可不用过去完成时,而只用一般过去时。例如:
Our teacher told us that Columbus discovered America in 1492.

A. read;was falling B. was reading; fell C. was reading; was falling D. read;fell
答案B.句中的as = when, while,意为"当……之时"。描述一件事发生的背景时,用过去进行;一个长动作发生的时候,另一个短动作发生。句意为 "在她看报纸时,奶奶睡着了。"句中的 fell(fall的过去时),是系动词,后跟形容词,如:fall sick。
