这个行不?
Ⅱ 初中英语一般过去时的语法形式有哪几种
一般过去时主要表示过去某时发生的动作或情况。可以从以下几个方面来理解:
1)过去某个时间所发生的动作或存在的状态。e.g. I bought a new shirt yesterday. He was a worker two years ago.
2)过去一段时间内,经常性或习惯性的动作。e.g. When I was a child,I often played with fire. Li Lei always walked to school last term.
3)谈到已故人的情况时多用过去时。e.g. Lu Xun was a great writer.
4)有些发生时间不是很清楚的情况,实际是过去发生的,也应用过去时态。e.g. What did you say?
另外,还可用过去时表示委婉的语气。e.g. Could you lend me your pen?
其结构是"主语+动词的过去式"。be动词的过去式为was, were;行为动词的过去式有规则变化和不规则变化两种,规则变化有以下几种情况:1)直接在动词原形末尾加-ed. e.g. work-----worked; ask------asked; 2)以e结尾的动词只加-d. e.g. arrive-----arrived; like-----liked.3)末尾只有一个辅音字母的重读闭音节,应先双写这个辅音字母,再加-ed. e.g. shop-----shopped; 4)以"辅音字母+y"结尾的动词,先把y变成i,再加-ed. e.g. carry----carried; study------studied.有些动词变过去式是不规则的,e.g. fly------flew; break-----broke; teach-----taught. 这些需要象生单词一样记住.
其句式变化分为两种情况
1)含有be动词的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980?
2)含有行为动词的变否定句要在行为动词前加助动词didn't.,同时把动词变成原形; 变一般疑问句,在句首加助动词did,同时把动词变成原形. e.g. I bought a gift for my mum yesterday. I didn't buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday?
其时间状语为yesterday或由其构成的短语,e.g. yesterday morning; 由"last+时间"构成的短语, e.g. last year; 由"时间段+ago"构成的短语, e.g. three days ago; 另外,还有on the morning of Monday, just now等,以及一些表示过去时态的从句.注意,在宾语从句中主句为过去,一般从句也为过去.
Ⅲ 初中英语 一般过去时
被动语态可以这么理解吧:被...的,也就是说变成了形容词。形容词前面加be动词。

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 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.

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。
2) since +一段时间+ ago。例如:

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.

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。

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:

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。

be used to + doing: 对„„已感到习惯,或"习惯于",to是介词,后需加名词或动名词。 He is used to a vegetarian diet.
Scarf is used to taking a walk.(现在习惯于散步)
二、构成及变化
1. Be动词在一般过去时中的变化:
am 和is在一般过去时中变为was。(was not=wasn’t) are在一般过去时中变为were。(were not=weren’t)
带有was或were的句子,其否定、疑问的变化和is, am, are一样,即否定句在was或were后加not,一般疑问句把was或were调到句首。 2.行为动词在一般过去时中的变化: 肯定句 : 主语 + 动词的过去式 . I watched a film last Sunday .
否定句 : 主语+ didn’t + 动词原形. I didn’t watch a film last Sunday .
一般疑问句:Did + 主语 + 动词原形 ?
Did you watch a film last Sunday ? Yes, I did . No , I didn’t . 特殊疑问句:疑问词+ 以did 开头的一般疑问句 ? What did you do last Sunday ? 3、现在进行时
一、意义——当表示现在正在进行的动作或正在发生的事。 时间标志——now,句前的look ,listen
二、构成:be (am, is ,are )+动词现在分词-ing形式 肯定句: 主语 + be + 现在分词V-ing (+ 其他) I’m doing my homework now .
否定句:主语+be+not+动词-ing +其他. I’m not doing my homework now. 一般疑问句:Be+主语+动词-ing +其他?
Are you doing your home work now? Yes, I am . No , I’m not .
特殊疑问句:特殊疑问词+be+主语+动词-ing+其他? What are you doing now ? 三、现在分词的构成: (1)一般在动词末尾直接加ing,
(2)以不发音字母e结尾的动词,先去掉e,再加ing,
如 skate →skating make →making dance → dancing write → writing have → having ride → riding come → coming
(3)以重读闭音节结尾的动词,中间只有一个元音字母,词尾只有一个辅音字母,应双写末尾的辅音字母,再加ing, 如: putting running beginning stopping swimming shopping jogging sitting getting forgetting letting 四、现在进行时的基本用法:
4
a. 表示现在( 指说话人说话时) 正在发生的事情。
We are waiting for you.
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。 Mr. Green is writing another novel.

c. 表示渐变的动词有:get, grow, become, turn, run, go, begin等。
The leaves are turning red.

4 过去进行时

3) 常用的时间状语
this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while My brother fell while he was riding his bicycle and hurt himself. It was raining when they left the station.
一、过去进行时结构:
was/were + 动词的现在分词
否定句则在was/were后加一个not,疑问句将was/were提前则可。 如:He was reading a book at 5:00pm yesterday.
→He was not reading a book at 5:00 yesterday.
→Was he reading a book at 5:00 yesterday? (Yes, he was./ No, he wasn’t.) →What was he doing at 5:00 yesterday?
二、过去进行时用法:
1. 过去进行时主要表示过去某个时刻正在进行的动作,常和表示过去的状语连用。如: (just)then 那时,当时 at this/that time 在这/那时 yesterday afternoon昨天下午
at nine 在九点 last night 昨晚 (at)this time yesterday在昨天这个时候
但在不少情况下,没有表示时间的状语,这时需要通过上下文来表示。 ①What were you doing at nine last night? 昨晚九点的时候,你在做什么?
②I was watching TV at home yesterday afternoon. 我昨天下午正在家里看电视。 ③They were playing football at this time yesterday.昨天这个时候他们在踢足球。 2.过去进行时也可以表示过去某一段时间内正在进行的动作。常与those days, the whole morning, from 8:00 to 12:00 last night等时间状语连用。 (1)From 1983 to 1998 , he was teaching at Yale . 从1983到1998年,他正在耶鲁大学教书。 (2)They were building a bridge last winter . 去年冬天他们正在造一座桥。 (3) He was writing a book those days. 那几天他正在写一本书
3.过去进行时与频度副词always forever, continually, constantly等连用时表示过去经常反复的动作,常常带有埋怨、讨厌、赞扬或喜爱等情绪。 ⑴My sister was always forgetting things.(表示埋怨) ⑵He was always helping others. (表示赞扬) 4. 过去进行时表示过去将要发生的动作。
现在进行时可以表示将来的动作,同样,过去进行时也可以表示从过去某时看来将要发生的动作,常用在间接引语中。
①Lucy arrived in Beijing last Friday. But she was leaving for Hong Kong the next morning. 上周五Lucy到达北京,但第二天早晨就要动身去香港了。
②She asked him if he was coming back for lunch. 她问他午饭是否准备回来吃。 5、过去进行时和一般过去时的区别。

Ⅶ 初中英语八大时态
初中英语来中的八个基本时自态,即:一般现在时、一般过去时、一般将来时、过去将来时、现在进行时、过去进行时、现在完成时、过去完成时。
时态是一种动词形式,表示经常、反复发生的动作或行为,不同的时态用以表示不同的时间与方式。在语法里,时或时态表示行为发生的时间和说话时的关系。一般分为过去式、现在式、将来式,通常也有与表示动作进行或终止的进行式和完成式等体貌一起相连用的情况。
一般过去时与现在完成时的转换:
在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能。但是,可用别的表达方式:①瞬间动词用于“一段时间 + ago”的一般过去时的句型中;②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用。
一般现在时与现在进行时的转换
在一般现在时中,at加上名词表示“处于某种状态”,如at work(在工作),at school(上学、上课)等。此短语可与进行时态转换。
现在进行时与一般将来时的转换
在现在进行时态中go,come,leave,start,arrive等动词常与表示将来的时间状语连用表示将要发生的动作。
Ⅷ 初中英语语法 一般过去式和现在完成时区别练习
1、Both his parents look sad .Maybe they _________what's happened to him .
A. knew B. have known C. must know D.will know
答案 是 B . 因为原句中 Maybe 以表示“推测”, 用完成时表示对现在造成的“影响和结果”。 注意: 不要误选答案 C. 因为,文中并不强调“过去” 的意义。
2、He has _______ been to Shanghai , has he ?
A. already B.never C.ever D. still
选择 B.never 。 因为这是个反义疑问句的结构, 且后边用的是“has he ”, 即肯定疑问式, 根据反义疑问句构成的“前肯后否, 前否后肯”原则, 可知, 前面一定是“否定句”, 只有选项 B never 填入句中,才能构成否定句。 所以, 正确答案是 B.
3、Have you met Mr Li ______?
A. just B. ago C.before D. a moment ago
选择 C.before 这是个现在完成时的结构, 选项 A. just B. ago D. a moment ago 都是一般过去时的时间状语, 所以,都不对。 只有 C before 才能用在现在完成时的句子中。 因此, 正确的答案 是 C 。
4、The famous writer _____ one new book in the past two year
A. is writing B.was writing C.wrote D.has written
正确答案是 D 。
句子意思是:在过去的两年里, 这位著名的作家写了一本新书。
in the past two year 意思是 在过去的两年里, 也包含“现在”, 因此, 属于现在完成时的范畴。 所以, 要选择现在完成时的答案。
5、-Our country ______ a lot so far .
