2. since，for在現在完成（進行）時中的用法差異
(1) since 后接過去的時間點或一般過去時的從句。
he has been an english teacher since three years ago.
we have known each other since we came to study in this university.
(2) for后接時間段
he has lived here for three years.
3. 現在完成時與一般過去時的區別
現在完成時表示過去發生的某一動作對現在造成的影響和結果，強調的是現在的情況，所以它不能和表示過去的時間狀語連用，如：yesterday, last night, three weeks ago, in 1990等。
而一般過去時只表示過去的動作或狀態，和現在不發生關系，它可以和表示過去的時間狀語連用。如：
he has lived here since 1992. 1992年以來他一直住在這里。（他現在還住在這里）
he lived here in 1992. 1992年他住在這里。（并不涉及他現在是否住在這里）
