How long has the girl been away from her home？．

Answer 1

分析 How long has the girl been away from her home？

解答 答案：How long has the girl been away from her home？這里是說女孩已經(jīng)離開，持續(xù)了一段時間了，用現(xiàn)在完成時have/has+過去分詞，這里是特殊疑問句，疑問詞是how long多久，后加一般疑問句語序，主語是the girl，故How long has the girl，這里的離開leave是短暫性動詞，需換成表狀態(tài)的持續(xù)性動詞結(jié)構(gòu)be away from，be的過去分詞been，加上賓語her home，故答案是How long has the girl been away from her home？

點評 本題是現(xiàn)在完成時的特殊疑問句，一定要注意這里不能用短暫性動詞，常見的用be+形容詞或副詞替換短暫性動詞的有
  die→be dead       leave→be away（from）   finish/end→be over    begin/start→be on   open→be open        close→be closed        come here→be here    come back→be back marry→be married     fall asleep/get to sleep→be asleep return→be back
