展开全部
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、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。）
