英语高手进：It seems that she will not come tomorrow.这句话里面it是形式主语么 It seems that John will not come here today. It seems that it will going to snow tomorrow.这句话通顺吗? 英语it形式主语问题老师说it + 实意动词就不是形式主语,必须是it is,it seems , it occurs这 It is a pity that he could not come .这句话是主语从句吗?请分析一下句子成分, It seems that she will come back soon.(改写同义句) It seems that 和 It seems as if中的是形式主语吧?真正的主语呢?逻辑主语呢?（请详细一点, It is.that..这句形式主语里面 It seems that they will win the game.该怎么讲解是主语从句? 请英语高手指教一下，这句话中的it是否为形式主语？ that,it,math,did,well,seems,not,do,she,in It seems that是宾语从句还是主语从句
