1.现在完成时的构成：主语+have/has +dne 要熟练掌握其肯定、否定和一般疑问形式及其简略回答。2.现在完成时的用法：“未完成表延续”指动作从过去某一时间开始一直延续到现在（包括现在在内），可以和表示延续的时间状语连用（一般是fr 或since)。谓语动词必须是延续性或状态性动词。

A: D yu have/wn a(n) _______ ?B: Yes, I d.A: Hw lng have yu had/wned it?B: I’ve had it fr/since…

He has stayed here since 5 ’clck.She has taught English since he came here.He has stayed here since 5 hurs ag.He has kept the bk fr 2 weeks.
since＋时间点＝fr＋时间段; since tw weeks ag=
