一般现在时,一般过去时
一般现在时
一、构成
一般现在时除主语是第三人称单数时谓语动词要加s外,一律用动词原形.
二、用法
■一般现在时表示经常性或习惯性的动作,常与表示频度的时间状语every day,usually,always,often,sometimes,on Sunday等连用.如:
I go to school at 6 every morning.每天早上我七点去上学.
■一般现在时表示客观存在及普遍真理.如:
Summer follows spring.春天之后是夏天.
The sun rises in the east.太阳从东方升起.
注意:此种用法即使出现在过去的语境中,仍用一般现在时.如:
I learned that the earth goes around the sun when I was in primary school.我在小学就学过地球是围绕太阳转的.
■一般现在时表示格言或警句.如:
Pride goes before a fall.骄者必败.
■一般现在时表示目前的情况或状态.如:
I am a teacher.我是教师.
Peter writes good Chinese but does not speak well.彼得汉语写得不错,讲的可不行.
■在下列情况下表示将来:
1.在状语从句中用一般现在时代替一般将来时.如:
I will give it to him as soon as I see him.我一看见他就交给他.
He will come if you invite him.如果你请他,他会来的.
Suppose he doesn’t agree,what shall we do?假如他不同意,那怎么办?
I shall do as I please.我高兴怎么做就怎么做.
He will continue the work no matter what happens.不管发生什么情况他都要继续这项工作.
2.表示按计划或时间表将要发生的动作,通常有表示将来的时间状语.如:
The plane takes off at 11:30 and arrives in Shanghai at l:20.飞机十一点半起飞,一点二十分抵达上海.
注:只限于少数动词能这样用,如 begin,start,,end,finish,stop,go,come,leave,sail,arrive,return,close,open 等.
一般过去时
一般过去时用动词的过去式构成,即在动词原形后加ed.
二、用法说明
■表示在过去某个时间所发生的动作或所处的状态.常与yesterday,last week,in 1989,just now,a moment ago,the other day等连用.如:
He was here just now.他刚才还在这里.
What did you do yesterday?你昨天做了什么事?
■在过去一段时间内的经常性或习惯性动作.如:
We often played together when we were children.我们小时候常在一起玩.
注:表示过去经常发生的动作还可用used to 和would.如:
He used to smoke a lot,but he doesn’t now.他过去经常抽烟,但现在不抽了.
Whenever we were in trouble,he would help us.每当我们遇到困难,他都会帮助我们.
■表示主语过去的特征或性格.如:
At that time she was very good at English.那时她英语学得很好.
■用在状语从句中表示过去将来.如:
He said he would wait until they came back.
■一般过去时有时可以表示现在,多与 want,hope,wonder,think,intend 等动词连用,使语气更委婉.如:
I wondered if you could help me.不知你能不能帮我一下.
有时用一般过去时也是时态一致的需要.如:
I didn’t know you were here.没想到你在这里.
注意:
1.表示一系列的动作,尽管有先后,都用一般过去时,最后两个动词之间用and连结.如:
He opened the door,rushed out and then disappeared.他打开门,冲了出去,然后就消失了.
2.注意在语境中理解“我刚才/原来还不……”.如:
—Your phone number again?I didn’t quite catch it.—It’s 2566666.请再说一次你的电话号码,好吗?我刚才没听清楚.是2566666.

一般现在时表示经常的,习惯性的动作或状态
一般过去时表示动作发生在过去,与过去的时间状语连用

一、巧记一般过去时:
动词一般过去时,表示过去发生的事;be用was或用were, have,has变had;
谓语动词过去式,过去时间作标志;一般动词加-ed,若是特殊得硬记。
否定句很简单,主语之后didn’t添;
疑问句也不难,did放在主语前; 不含be动词时
如果谓语之前有did,谓语动词需还原;
动词若是was,we...

一、巧记一般过去时:
动词一般过去时,表示过去发生的事;be用was或用were, have,has变had;
谓语动词过去式,过去时间作标志;一般动词加-ed,若是特殊得硬记。
否定句很简单,主语之后didn’t添;
疑问句也不难,did放在主语前; 不含be动词时
如果谓语之前有did,谓语动词需还原;
动词若是was,were,否定就把not添。 含be动词时
疑问句也不难,要把was,were放在主语前。
二、be的一般过去时:学习动词be的一般过去时,下面有一口诀,它可以帮你们更好地掌
握动词be的一般过去时。 be的过去时有四巧:
一是时间状语巧, 表示过去的短语要记牢;
二是形式巧,单数was,复数were;
三巧是否定句结构,not紧跟was/were;
四是疑问句式巧,was/were向前跑(提前)。
【一巧】时间状语(即标志词)巧。一般过去时表示过去发生的动作或存在的状态,恰巧
与表示过去的一些时间状语连用。
【二巧】形式巧。它与一般现在时一样,形式多样:当主语是第一人称单数或第三人称单
数时,谓语动词用was;主语是第二人称或其他人称复数时,谓语动词用were。
例如: I was in the classroom yesterday morning. 昨天早上我在教室里。
He was at school last Tuesday. 上周二他在学校。
They were over there a moment ago. 刚才他们在那边。
【三巧】否定句结构巧。与动词be的一般现在时一样,它在动词后面加not即可变成否定
句,并且was, were与not可以缩写成wasn't, weren't。即:
主语 + wasn't/ weren't + 表语 + 其他。例如:
I was not (=wasn't) here yesterday. 昨天我不在这儿。
My parents were not (=weren't) at home last Sunday. 上周日我父母不在家。
【四巧】 疑问句式巧。把was, were提到句首,句末用问号即可变为一般疑问句。即:
Was(Were) + 主语 +表语 + 其他?这恰巧与动词be的一般现在时的疑问句
式相似。例如: Were you at home the day before yesterday﹖ 前天你在家吗?
Was she late this morning﹖今天早上她迟到了吗?
更巧的是疑问句的答语也相似,肯定回答用“Yes, 主语+was/were.”;
否定回答用“No,主语+wasn't/weren't.”。
例如:—Were Wei Hua and Han Mei here just now﹖ 刚才魏华和韩梅在这儿吗?
—Yes, they were. (No, they weren't.) 是的,她们在。(不,她们不在。)
