2.过去已经开始，持续到现在的动作或状态，

常与for或since引起的一段时间状语连用。

动词构成：have/has+v过去分词

have breakfast

I have just had my breakfast.

(现在我不饿)

I’m not hungry now

moved here

in 2004

I still live here

I have lived here for three years.

I have lived here since three years ago.

now

past

现在完成时：表示过去发生或已经完成的某一动作对现在造成的影响或结果，或从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，不能和表示过去的时间状语连用（如：in 1990，last Sunday 等）。

一般过去时：一般过去时只表示过去的动作或状态，和现在不发生关系（即动作或状态在现在已经结束），它可以和表示过去的时间状语连用。

现在完成时与一般过去时的区别：

have / has + V过去分词

How long have you had that bike over there?

I've had it for three years.

How long has his son owned the train and railway set?

He’s owned it since his fourth birthday.

Have you ever played football?

Yes, I did when I was little, but I haven't played for a while now.

Grammar Focus

for 和 since 在现在完成时中的应用

for与since都能与现在完成时连用，但区别较大：

（1）for后须接“时间段”

He has studied English for three years.

他学英语3年了。
