利用时间数轴讲解时态
英语时态多,学生在学习过程中很难理解掌握。

我通过多年的教学实践,建立了一个时间数轴,可帮助学生理解和掌握时态的应用。

时间数轴的概念:原点表示现在,箭头方向(原点右边)表示将来,箭头反方向(原点左边)表示过去。

如图所示:
1.一般现在时:表示现阶段经常性的动作或状态。

例如:
I often go to school at 7:00 in the morning.
She sometimes plays tabletennis after school.
You are students.
2.现在进行时:表示现在正在进行的动作。

例如
I’m speaking.
You are listening to me.
They are playing basketball now.
3.一般过去时:表示过去发生的动作或状态,或者过去发生的经常性动作。

例如
I did a lot of work on the cinema last Saturday.
They lived here last year.
LeiFeng was born in a poor family.
4.过去进行时:表示过去某时刻正在进行的动作。

例如
My mother was cooking when I got home yesterday.
I saw some children were playing in the street last night.
He said they were looking for a dog.
5.现在完成时:表示从过去开始持续到现在的动作。

例如
He has been here for 5 years.
现在完成时:表示动作发生在过去但对现在造成了影响。

例如
She has gone to Beijing.
He has been to Shanghai.
6.一般将来时:表示将来的动作或状态.
I will be a doctor when I grow up.
Her father will buy a bike for her next Sunday.
7.过去完成时:表示过去的过去动作或状态。

例如
He said his sister had drawn a good picture.
My teacher asked me what we had done the day before.
The stutents had finished their homework before they played football. The teacher said he had been a teacher for thirty years.
8.过去将来时:表示过去的将来动作或状态。

He said that he would come to see me again in two days time.
She asked her husband if he would never go to bed that night.
The boy would go skating in spite of my warning that the ice was too thin. (作者单位:724400陕西省宁强县第二中学)。
