they are certainly not mine这句话为什么不用certain,certainly是副词,为什么可

They are certainly heroes,这句为什么不用certain,不是形容词修饰名词么? 为什么是are you certain 不是are you certainly It is certainly not for me是否等于It is not certainly for me?为什么 It‘s certainly not for me!能否写成It is not certainly for me!为什么 certainly不是副词吗 为什么可以单独成句 英语翻译在这句话中：Certainly they do not constitute themselves a 'col It seemed certain that the plane would crash为什么不是certainly呢? for certain=certainly吗? 英语翻译They are certainly not putting any live pandas at risk,s certainly.here you are for certain和certainly的区别 It's certainly not for me.这里面certainly不是副词吗?怎么能修饰be动词呢?
