【导语】海阔凭你跃,天高任你飞。愿你信心满满,尽展聪明才智;妙笔生花,谱下锦绣第几篇。学习的敌人是自己的知足,要使自己学一点东西,必需从不自满开始。以下是本站为大家整理的《小学一年级英语语法【四篇】》 供您查阅。
【第一篇: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.
【第二篇:过去进行时】
过去进行时主要用于:
表示过去某个时刻或阶段正在进行的动作。
e.g. At that time she was working in a PLA unit.
那时她在解放军某部工作。
What were you doing this time yesterday?
与这个时态连用的时间状语常用:
at nine o`clock, this time last night, these days, at that time 等。
用 when 引导的时间状语从句表示主句的动作正在进行的时间。
e.g. When he came in, I was reading a newspaper.
注:
1 、 while 引导时间状语从句叙述过去的动作时,从句常用过去进行时。
e.g. I read a magazine while I was waiting for the bus.
2 、 when 用作并列连词,意为"这时",连接两分句时,第一句多用过去进行时。
e.g. I was reading a newspaper when he came in.
一般过去时与过去进行时的区别:
一般过去时:强调过去某一时间开始或完成的动作。
过去进行时:强调过去某一时间正在进行的动作。
试区别下面两句: We were building a reservoir last winter.
去年冬天我们在修建一座水库。(可能尚未建成) We built a reservoir last winter.
去年冬天我们修建了一座水库。(已经建成)
【第三篇:现在进行时】
现在进行时主要用于:
1 、表示现在或现阶段正在进行的动作。
e.g. Listen, someone is crying.
What are you doing these days?
2 、代替一般现在时,表示经常性动作或状态,而含有某种感情色彩。
e.g. How are you feeling today?
你今天感觉怎样?(显得亲切)
He is doing well in his lessons.
他的功课很好。(赞扬)
You are always boasting.
你老爱吹牛。(厌烦)
3 、动词 go, come, leave, arrive 等表将要发生的动作时。
e.g. They are leaving for Shanghai.
与这种时态连用的时间状语常有:
now, these days, recently, this week 等。
【第四篇:过去完成时】
1 、过去完成时是一个相对时态,表示过去的过去,只有在两个过去发生的动作相比较时才可显示出来。
e.g. As soon as we got to the station, the train had left.
注:主从句表达的动作紧接时,即两动作发生的时间没有明显时间上的悬殊或空档时,主从句都可用一般过去时。
e.g. Where did your brother study before he joined the army?
2 、过去完成时可表示截止过去某一时间动作的总或动作的结束。
e.g. By the end of last month. We had reviewed four books
By eight o`clock, he had finished his homework.
与这个时态连用的时间状语常有:
by 1985, by eight o`clock, by then, by the end of last month, by the time when, when, as soon as, before 等连词引导的时间状语从句,表示主句动作结束的时间。
