l have no idea when he____get back____the USA l have no idea.what______you I have no idea what——when l was awayA.had happenedB.had happenedC.happenedD.will happen l have no idea when he will be back这为什么是同位语从句?我觉得是定语从句. 英语翻译I have no idea when ____ ____ ____ ____ . when?How?Why?I have no idea about these!翻译 l have no idea.同义句l____ _____. I have no idea have no idea 造句 when l have no work to do. 同位语从句与定语从句判断,实例l have no idea when he will be back这个是哪个,为什么 have no idea后面可以接when,that,whether,where等吗?比如I have no idea when he was ill. l have no idea when he will be back请分析此句语法.请问这句话中,是不是he will be back充当了受词idea的同位语?整句话属於同位语从句么? l have no idea what l should do next(改成同义句) have no idea的用法 英语语法问题-请问这是一个什么从句?We have no idea when she was born I have no idea when he will be back速度点 高手进!when能不能换成whether? 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
