Any idea when he might be back?是什么意思啊?

Any idea when he might be back?是什么意思啊? 英语好点的帮哈忙嘛谢谢he,when,any idea,might,be back这几个词连词成句,还不能加减任何词语进去…… 请帮我解释：Any idea when she might be back? is there any diffrences between your idea and ------(his he her she)please call me when Li ----(arrive正确形式)help ----(youself正确形式）to some fish my children. He has no idea同意句He---- ------只有两个空啊He doesn't have any idea.这个我也知道！ is there any difference between you idea and______?A he B his C all D her a:any idea when she might be back?b:well,she shouldn't be long.she said she was just going topost some letters.前面的any idea when she might be back? Do you have any idea when ho.ll be back 中文怎么写?要准确点的. when I told him my idea,he (agree) with me.填啥 have no idea后面可以接when,that,whether,where等吗?比如I have no idea when he was ill. 这句话“i have no idea when he will be back这句话“i have no idea when he will be back ”这里为什么要用be 不直接when he will back 呢 I have no idea when he will be back速度点 高手进!when能不能换成whether? 英语题+++++++++++++++++++++++++++++++++++++++111IS there any differece between your idea and ____A.he B.his C.she D.her He didn't play football any longer when he was forty years old.改为同义句He____ ____ football when accident event afffair incident 的区别1.A journalist will soon be sent to cover the ______2.
