so和as的倒装句怎样区别高一下的第十三单元:Our eating habits have changed , as h

1.这两者区别很简单,即：as = and so
2.在此种倒装情况下,如果单独用so,则前后是两个并列句.
两个并列句之间如果没有其他并列连词时,是不能用逗号和so并列这两个句子的,原因就在于此时的so是个副词而非连词.
这时就必须要求so前面用句号,当然so还要首字母大写.当然,也可以再加入and.
但是如果用as,as本身是个连词,所以无须再加and了.
3.如：He is a teacher,and so is his wife.√
=He is a teacher.So is his wife.√
=He is a teacher,as is his wife.√
而：He is a teacher,so is his wife.×

这里 as 表示“。。。也如此”“同样”
此处不能换为so,因为两者没有因果关系
