⑵ 初中英语语法大全
学英语一开始要学发音。英语是拼音文字,由字母组单字。英语字母共有二十六个,其中字母a、e、i、o、u是元音字母,其余二十一个是辅音字母,其中y字母有时当元音字母用。每个字母可以有一个或一个以上的读音,因此,英语语音共有五十个音位,音位的书写形式是音位字母,即音标符号,一个音位字母即音标,表示一个音位,所以,必须先学习五十个KK音标,然后根据发音规则拼读单字。下面是一些常用的发音规则。
一、辅音字母在单字中的发音一般是一对一的,如p-b、t-d、k(qu)、f-v、s-z、r、h、j、m、n、l、w就发它的本音,一般字母和音标写法一致,或者字母名称当中,包含了这个字母的音素。
二、有些辅音字母有多个发音。如:字母c后面接a,o,u的时候,c的发音与字母k发音相同,叫做“hard c sound”,当字母c后面接e,i,或y的时候,通常c的发音与字母s发音相同,叫做“soft c sound” 。有时在e或i前面,c会发/ʃ/音。字母g后面接a,o,u的时候,所发的音叫做“hard g sound” ,当字母g后面接e,i,或y的时候,有时g的发音与字母j的发音相同,叫做“软g音”。x在单词中间或结尾时发/ks/音,在单词中间时有时发/gz/音,在单词起始位置时发/z/音。y在单词起始位置时发音为辅音/j/,单词或音节中间或结尾时被当做元音,在重读开音节里发长元音/aɪ/,在重读闭音节里和词末发短元音/ɪ/。
三、辅音字母组合的发音也是有规律可循的。常见的辅音字母组合有:tr-dr,发音时舌身与r相似,舌尖贴上齿龈后部,气流冲破阻碍发出短促的t-d后立刻发r。ck只发一个k的音,ng的发音是舌头抵住上颚后方所发出的鼻音,n在k之前也这样发音。
四、复合字母构成的单音。digraph是两个(或三个)辅音字母在一起只发一个音,通常指以下四种组合:ch(tch),sh,wh和th。ch发/tʃ/音,sh发/ʃ/音,一般来说wh发/hw/音(清辅音),但在o前面发/h/音,th的发音则需要一些记忆力了,在虚词和一部分代词中发浊音(舌尖在上下牙齿中间,声带需要振动,声音从牙齿和舌头之间的缝隙里出来),其它以th开始的单词基本上都发清音(舌尖在上下牙齿中间,声音从牙齿和舌头之间的缝隙里出来,但是声带不振动)。
五、在有些辅音字母组合中,其中一个字母是不发音的,如kn中的k、ps中的p、mb和bt里的b、mn里的m、wr中的w。在罗曼语族词汇里,辅音字母h一般也不发音;而在法语词源的外来语里,辅音字母在词末也不发音,如depot、ballet、faux pas等。
六、英语里元音的发音比较复杂,每个元音都可以发多个音,掌握了元音的发音规律才能对整个单词的发音有比较准确的掌握。元音字母有五个:a,e,i,o,u,另外y在一个单词的中间或结尾时也被当做元音。每个单词里都包含有至少一个元音,元音是单词的“最强音”。元音所发的音取决于该元音在单词中的位置或它是如何与其它元音组合的。一般来说,如果五个元音字母中的任意一个后面紧接着一个或几个辅音字母,这个元音字母就处于重读闭音节中,发成短音:a发/æ/、e发/ɛ/、i和y都发/ɪ/音、o发/α/、u发/ʌ/音。
七、如果一个单词以字母e结尾,前面的元音发长音,叫做重读相对开音节(magic e)。如果一个元音是在一个单词或重读音节的结尾,该元音也发长音,叫做重读开音节,所谓长音就是元音字母的名字,如:a的长音为/e/,e的长音为/i/,i和y的长音都是/aɪ/,o的长音为/o/,u的长音为/ju/。重读相对开音节结尾的字母e只起到让前面的元音发长音的作用,自己是不发音的。
八、当一个单词或音节里有两个元音时,通常第一个元音发长音,第二个元音不发音,叫做vowel digraph。但是al、au、aw、ou、o有时发/ɔ/这个音,也是长元音。但是,在一些特殊情况下,元音后面紧接着辅音字母的时候,该元音是发长音的。如o在st、ld前,i在gh、gn、ld、nd前都要发长音,但元音字母o接st时有时也发成长元音/ɔ/,如cost,lost等。
九、双元音是两个元音音素组合在一起的,所以听上去有两个音,尽管这两个音并不是两个元音所单独发出的,如oi(oy)和ou(ow)分别发/ɔɪ/和/aʊ/音。
十、元音字母与r结合起来后,发卷舌音,如ar发/αr/、or发/ɔr/、er、ir、ur都发/ɝ/。
十一、五个元音字母在非重读音节中发弱元音/ə/。
学会了发音后,再开始学词汇和语法。英语属于印欧语系的日耳曼西部语支,英语的词汇有开放性,一部分是日耳曼语族词汇,一部分是罗曼语族词汇,还有一部分是从法语、德语、西班牙语、意大利语、拉丁语、希腊语、阿拉伯语以及其它语言引进的词汇。英语属于屈折语,但是它的屈折变化形式相对比较少,除了名词、代词、动词、形容词、副词有词形变化外,数词、冠词、介系词、连接词、感叹词都是不变的,只有简单句、并列句、复合句三种句子结构,词序比较固定。只要你用心学,一定能学好英语这门语言的,希望我能帮助到你。

。例如:I thought
you might have some. 我以为你想要一些。
比较:Christine was an invalid all her life.(含义:她已不在人间。)

典型例题
---- Your phone number again? I ___ quite catch it.
---- It's 69568442.
A. didn't B. couldn't C. don't D. can't
答案A. 本句虽没有明确的时间状语,但从语意上看出,在听的时候没有听懂这个动作发生在过去,因此应用过
去时。
11.4 一般将来时
1) shall用于第一人称,常被will 所代替。will 在陈述句中用于各人称,在征求意见时常用于第二人称。例
如:
Which paragraph shall I read first? 我先读哪一段呢?
Will you be at home at seven this evening? 今晚七点回家好吗?
2) be going to +不定式,表示将来。

明天下午我想去踢球。(主观安排)
11.7 一般现在时表将来
1)下列动词come, go, arrive, leave, start, begin,
return的一般现在时可以表示将来,主要用来表示在时间上已确定或安排好的事情。例如:
The train leaves at six tomorrow morning. 火车明天上午六点开。

return等现在进行时可以表示将来。例如:

11.9 现在完成时
现在完成时用来表示之前已发生或完成的动作或状态,其结果的影响现在还存在;也可表示持续到现在的动作
或状态。其构成:have
(has) +过去分词。
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

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:

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.
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.
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。
2) since +一段时间+ ago。例如:
I have been here since five months ago. 我在这儿,已经有五个月了。
3) since +从句。例如:
Great changes have taken place since you left. 你走后,变化可大了。
Great changes have taken place since we were here. 我们走后,变化可大了。
4) It is +一段时间+ since从句。例如:
It is two years since I became a postgraate student.
我考上研究生有两年了。
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。
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
1) 两个动作如按顺序发生,又不强调先后,或用then,and,but 等连词时,多用一般过去时。例如:
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.
11.17 将来完成时
1) 构成will have done
2) 概念
a. 状态完成:表示某事继续到将来某一时为止一直有的状态。例如:
They will have been married for 20 years by then.
到那时他们结婚将有二十年了。
b. 动作完成:表示将来某一时或另一个将来的动作之前,已经完成的动作或获得的经验。例如:
You will have reached Shanghai by this time tomorrow.
明天此时,你已经到达上海了。
11.18 现在进行时
现在进行时的基本用法:
a. 表示现在(指说话人说话时)正在发生的事情。例如:
We are waiting for you. 我们正在等你。
b. 习惯进行:表示长期的或重复性的动作,说话时动作未必正在进行。例如:
Mr. Green is writing another novel.
他在写另一部小说。(说话时并未在写,只处于写作的状态。)
c. 表示渐变,这样的动词有:get, grow, become, turn, run, go, begin等。例如:
The leaves are turning red. 叶子在变红。
It's getting warmer and warmer. 天越来越热了。
d. 与always, constantly, forever
等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。例如:
You are always changing your mind. 你老是改变主意。
典型例题
My dictionary ___, I have looked for it everywhere but
still___ it.
A. has lost, don't find B. is missing, don't find C. has lost,
haven't found D. is missing, haven't found.
答案D. 前句是一个仍在持续的状态,应用进行时,由于没有找到,其影响仍然存在,应用完成时,瞬间动词用
于否定式时可用于完成时。
11.19 不用进行时的动词
1)表示事实状态的动词,如have, belong, possess, cost, owe, exist, include,
contain, matter, weigh, measure, continue等。例如:I have two
brothers. 我有两兄弟。
This house belongs to my sister. 这房子是我姐的。
2)表示心理状态的动词,如know, realize, think see, believe, suppose,
imagine, agree, recognize, remember, want, need, forget,
prefer, mean, understand, love, hate等。例如:I need your help.
我需要你的帮助。
He loves her very much. 他爱她很深。
3)瞬间动词,如accept, receive, complete, finish, give, allow,

,因此用过去进行时。
2) As she ___ the newspaper, Granny ___ asleep.
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

顺口溜:本领最多不定式,主表定补宾和状;样样成分都能干,只有谓语它不敢;大家千万要小心,有时它把句型改;作主语时用it,自己在后把身藏;七个感官三使役,宾补要把to甩开;疑问词后接上它,宾语从句可充当;逻辑主语不定式,不定式前加for sb.;to前not是否定,各种用法区别开。
以下是不带to的动词不定式(即动词原形)的常见用法
★ let sb. do sth让某人做某事 ★ make do sth使得某人做某事
★ hear do sth do sth听见某人做某事 ★see do sth do sth看见某人做某事
★why not/why don’t you +动原?为什么不.?Why not/Why don’t you take a walk?
★ 某人+had better( not)do 某人最好(不)做某事
★情态动词can/may /must /should+ 动词原(包括情态动词的否定形式+动词原形)
★ 助动词do/does/did/will/would在构成疑问句或者构成否定句即don’t /doesn’t /didn’t /will not /would not+ 动词原形
★ be going to + 动词原形(表示“即将”“打算” 做某事)

11.2 一般过去时的用法

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)
He has been in the League for three years. (在团内的状态可延续)
He has been a League member for three years. (是团员的状态可持续)
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.
返回动词的时态目录
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。
2) since +一段时间+ ago。例如:

It is two years since I became a postgraate student. 我考上研究生有两年了。
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。

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:

典型例题

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。
