初中英语since和for的区别

我们都知道在各个科目的学习中，对必考知识点进行归纳总结可以有效地帮助我们的学习，在初中英语中当然也不例外。针对初中英语的学习，我们学大教育专家为大家带来了初中英语since和for的区别，希望可以更好地帮助同学们对于初中英语这门学科的学习。

since和for的区别

Since 用来说明动作起始时间，for用来说明动作延续时间长度。

I have lived here for more than twenty years.

I have lived here since I was born..

My aunt has worked in a clinic since 1949.

Some new oilfields have been opened up since 1976.

I have known Xiao Li since she was a little girl.

My brother has been in the Youth League for two years.

I have not heard from my uncle for a long time.

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。)

小窍门：

当现在完成时+一段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。

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.
