小学英语语法-时态篇
小学英语语法 一般过去时态
（a） be 动词的过去式:
I/He/she/it was(not)…. You/we/they were….
一般疑问句was, were 放在句首。
（b） 动词过去式：
肯定句： I watched cartoons.
She visited the zoo.
一般疑问句： Did you read book last night? Yes, I did. No, I didn't.
Did she clean the desk just now? Yes, she did. No, she didn't.
否定句： They didn't go the the part yesterday.
He didn't make model ships last week.
小学英语语法 一般现在时
通常用 "usually, often, every day, sometimes"。
肯定句：
I go to school on foot every day.
She goes to school on foot every day.
一般疑问句:
Do you jump high? Yes, I do. / No, I don't.
Does he jump high? Yes, he does. / No, he doesn't.
否定句： We don't go to school on Sundays.
My mother doesn't like watching TV in the evening.
小学英语语法 一般将来时
一般将来时主要用于：
表示将要发生的动作或情况
e.g. Tom will have a bike of his own.
与这个时态连用的时间状语常用：
tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
一般将来时态与其它结构表将来情况的区别：
一般将来时态 ：主要从时间的角度表将要发生的动作或情况。
be going to 结构 ：①表（主观上）打算或准备做某事时。 ②表有发生某事的预兆时。
e.g. They are going to have a competition with us in studies. It is going to rain.
据以上区别，故下面一句是错的：
I am going to be eighteen years old next year.
应改为： I shall be eighteen years old next year.
be about to do sth 结构 ：意为"刚要做某事"、"马上要做某事"强调时间之紧迫性。
e.g. We are about to discuss this problem.
小学英语语法 一般过去时现在完成时
一般过去时现在完成时主要用于：
1 、表示到现在为止这一时期中发生的`动作或情况，即多次动作的总和。
e.g. We have learnt four English songs this month.
How many times have you read the novel?
For many days we haven`t seen each other.
2 、表示对现在有影响的某一已发生的动作。
e.g. The delegation has left 代表团已经走了（说明现在不在这里）
Look, what you have done. 看你干的事。
与这一时态连用的时间状语有：
already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短语，连词 since 引导的时间状语从句。
一般过去时与现在完成时的区别：
一般过去时：重在说明动作在过去发生时的具体情况（时间、地点、方式、对象、细节等）。
现在完成时：只提起已发生的动作（事实）及其影响，不说明动作发生时的具体情况。
cf. Have you had your lunch?
What did you have for lunch?
I have ever been to the Great Wall,_and_I went there last summer with my father.
注：现在完成时表达的动作常具有反复性，故下面一句是错的：
Have you seen the six thirty`s news program?
应改为：
Did you see the six thirty`s news program?
小学英语语法 一般过去时
一般过去时主要用于：
1 、表示过去某个时间发生的动作或情况（包括习惯性的动作或状态）
e.g. When did you read the novel?
She often came to help us in those days.
2 、谈到过去的情况时
e.g. I didn`t know you were so busy.
3 、谈到已死人的情况时
e.g. Lei Feng was a great communist fighter.
与这个时态连用的时间状语常有：
yesterday, last night, the other day, two months ago, in 1985, then, just now,
when, after, as soon as 引导的时间状语从句，表示主句动作开始的时间。
