小学英语语法-时态篇

  小学英语语法-时态篇 1

  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.

  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.

  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.

  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?

  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。
