Sometimes it isn＇t easy being the kid at school.什么在这里是形式主语,什么才是真正的主语,这样做是为了避免头重脚轻. It isn't easy ______ (be) a new student in the school.,可是在新目标英语书中是填being 而不是to be ,在习题中又常考, Being _______(live) is a beautiful thing,isn't it it isn't easy being the new kids at school.为什么用being而不是to beit is +adj+to do sth这里用这样不是说可以 it is +adj+doing sth 分析这个句子：it isn't easy being the new kid at schoolit isn't easy 是形式主语,being the new kid at school是真正主语.动名词形式和to do形式,都可以用it引导的形式主语吗,二者有没有什么区别? it isn't easy 后面是跟DOING吗?为什么?是因为EASY?
