我们应当充分发挥组织者和引导者的作用,威廉希尔app 初中频道为大家准备了初中英语词汇,欢迎阅读与选择!

比较since和for

Since 用来说明动作起始时间,for用来说明动作延续时间长度。例如:

I have lived here for more than twenty years.我住在这儿二十多年了。

I have lived here since I was born. 我从出生起就住在这儿了。

注意:并非有for 作为时间状语的句子都用现在完成时。

I worked here for more than twenty years. (我现在已不在这里工作。)

I have worked here for many years.(现在我仍在这里工作。)

注意:用句型转换的方法,很容易排除非延续动词在有for/since结构的完成时中的误用。

1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.

2)(错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.

显然,第二句不对,它应改为 Harry got married six years ago. 或 Harry has been married for six years.

欢迎大家去阅读由小编为大家提供的初中英语词汇大家好好去品味了吗?希望能够帮助到大家,加油哦!
