（watch) a TV play ,I heard someone knocking at the window.句首是填WATCHING 还是WHEN WATCHING?
（not,receive)a play,Mary decided to send Jack another e-mail.填HAVING NOT RECEIVED对不对?
没有分了,

第一句是watching,因为完整的是when i was watching a tv play,于是省略了前面,只留下了watching a tv play.
第二句亲写的是正确的,主语是MARY,有表示完成时态的意思.因为没有收到,所以要发email.having是必要的.

（watch) a TV play ,I heard someone knocking at the window.句首 I hear someone knocking at the door.的同义句 I heard someone _____(knock /knocking) at the door just now I heard someone ____(knocking/knocked)at the door just now. 将Eng文翻下.One day about a week ago,I heard someone knocking at i was watching tv when i heard the door(knocking) Listen!I hear someone knocking at the door （同义句转换） Listen!Th 初中英语 Listen!I hear someone knocking at the door.(同一句转换） List 一道同义句转换题,1.Listen!I hear someone knocking at the door.转换：Li "Did you heard someone knocking at the door?"为什么要用at? someone is knocking at the door （）i go and see who it is A s someone is knocking at the door .（）i go and see who it is A
