一个英语问题 I heard her singing an English song when一个英语问题I heard her singing an English song when I passed by her room yesterday.请问为什么时间状语前面可以用进行时? 非谓语的一个小问题i heard her crying when i walking past.i sat near her and heard her sing the new song.谁能给讲下这里hear 后面跟动词用这两种形式是为什么啊? 英语问题two years later,her father disappeared ,never ______again.A..to heard from B.being heard fromC.to be heard from D.be heard i heard from her yesterday的同义句 是8上的英语哟. 一道挺难的英语填空题Her name is n_______to me.I'v never heard of her before. i heard her singing.i heard her sing.有什么不同啊? 问一个英语时态的问题我从未听过这么好听的歌可不可以这样说：I had never heard so great a song? 翻译英语被动句 I HEARD HER SING THE SONG JUST NOW SHE WAS HEARD TO SING THE SONG JUST NOW 翻译 英语问题]【She was heard _______(sing) an English song in her home last night.】【要有理由】 英语高手帮个忙,I heard her __in the bedroom last night.A.cry B.cried C.crying D.criied可多选. 英语改为被动语态I heard her singing at8：00 last night.She at8：00 last night. 英语非谓语选择题i sat near her and heard her_____ the new songA.sing B.singing That’s the stupidest thing I’ve ever heard!求英语告诉速度回答! 是I heard her singing对还是I hear her singing对如果第一个对为什么要加过去态呢 I heard a letter from her还是I heard a letter from she? I heard from her yesterday 改同义句 I have not heard from her so far.翻译 i never heard her和i have never heard her两者在翻译上有什么区别
