  语法是学习英语非常关键的一个要点,那么一年级英语的语法有哪些呢?一起来看下吧!下面就是小编为大家整理的英语语法,希望对大家有所帮助!

  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。

  一般现在时

  一般现在时主要用于:

  1 、表示经常性或习惯性动作。

  e.g. It seldom snows here.

  2 、表示现在的特征或状态。

  e.g. He is always ready to help others.

  3 、普遍真理。

  e.g. Action speaks louder than words.

  4 、剧情图片介绍,背景说明,动作解说。

  e.g. (Tom enters the room_and_sits at the table)

  Doctor : What`s your trouble, young man?

  Tom : I`ve caught a cold, doctor.

  5 、时间、条件、让步、方式状语从句表将要发生的动作时。

  e.g. Tomorrow we shall go for an outing unless it rains.

  与这种时态连用的时间状语常有:

  always, often, never, seldom, usually, once, a week, now 等。

  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?
