3.現(xiàn)在完成時與一般過去時的區(qū)別：
1）
2）
4.表示“曾經(jīng)到過某地（人已回來）”用“have/has been to”,表示“到某地去了（還未回來）”用“have/has gone to”.例如：
——where is li hua? －h(huán)e has gone to the reading-room.
——she knows a lot about shanghai.－she has been there.
5.短暫動詞（即瞬間動詞），join,lose,buy,borrow,leave,go,come,arrive,die,
marry,finish,complete,begin,start,break out等，在完成時態(tài)中，其肯定式不能和表示一段時間的狀語連用。例如不能說：he has finished the work for three hours.要翻譯“他已完成工作三小時了。”
可采用1）“ago法”：he finished the work three hours ago.
2）“延續(xù)法”：he has been through(with)the work for three hours.
3）“since法”：it is/has been three hours since he finished the work.
