1)have/has gone to 表示去了,屬于瞬間動(dòng)詞(暫短性 動(dòng)詞),不與一段時(shí)間連用.
eg:-Where is Tom?
-He has gone to Shanghai.(他去了上海)言外 之意:他不在說話現(xiàn)場
如果表示去過則用has / have been to
eg:I have been to the Great Wall.(我去過長城)
另外,如果時(shí)間狀語是一段時(shí)間,也用has / have been to
eg:he has been there for two years.(兩年是時(shí)間段所以用been)
(2)同樣,has /have been away 和 has/have left 是對(duì)應(yīng)的,都表示離開,has/have been away 是延續(xù)性的,與時(shí)間段連用,has/ have left 是瞬間動(dòng)詞
eg :He has been away from that factory for two days.(離開兩天了)
eg:He has left from his office.(只表示離開)
