现在完成时用法（二）
此用法需注意两点：
1.常与for, since引导的时间段的时间状语连用。
2.动词使用延续性动词。
Language points
since, for 的用法:
since: 自……以来
1. since+时间点
·He has stayed here since 5 o’clock.
2. since+ 时间段+ ago
·He has stayed here since 5 hours ago.
3. since+ 从句(句子要用一般过去时态)
·She has taught English since he came here.
for: (长达)for+ 时间段
·He has kept the book for 2 weeks.
since＋一段时间＋ago＝for＋时间段;
since two weeks ago=for two weeks;
·I have kept the library book for a week.
= I have kept the library book since a week ago.
在现在完成时态中,for与since引导的时间状语可以相互转换。
It is + 时间段 +since + 一般过去时的句子.
