分析一道英语题目Jack is a student and studies at the NO.2 Middle sch

So it is with sb 某人也一样 和so is sb意思一样
但句子中有两个谓语动词 所以不能用 so is Mike
so + 助动词/be动词/情态动词+ 另一主语 ,表示另一主语的情况与前一个主语的情况相同.可以是一个人说的,也可以是对话中另一人说的.
so + 人称代词主格 + 助动词/be动词/情态动词 ,表示强调,是对话中对对方所说情况的赞同.
1.She is clever,and so is he.(她聪明,他也是）
2.Mary can swim,and so can Tom.（Mary会游泳,Tom也会）
3.I have seen the film,and so has my friend,Bob.(我看过这个电影,我的朋友Bob 也看过了）
4.Mr.Green went for his holiday last month,and so did his wife.(Mr.Green上个月去度假了,他妻子也去了）
5.The students will have a five-day holiday,and so will their teachers.(学生们将有五天假,老师们也有）
6.--She is a clever girl.--So she is.(确实是）

其它类似.
