neither do I so do I so I do的区别小弟先谢过了最好有例句

我也不...
我也....
所以我....

当两个句子中的主语不一致时，无论是so do I还是neither do I都要倒装。但前者是肯定回答，后者是否定。
如：He is clever。So do I。他和我是不同的主语，所以倒装。翻译为他和我都聪明。He’s not clever。Neither do I。翻译为他和我都不聪明。Nor可替换Neither。
当两个句子中的主语一致时。就不倒装了。如The weather is good。So it is。两句的主语都是天气，不倒装。翻译为天气很好啊，确实是这样

楼上回答是准确的

楼上错了！
neither do I/so do I 都是我也是，前者用于否定，后者用于肯定
so i do是“我的确如此”的意思

neither do i 我也不
so do i 我也是
so i do 确实如此
eg:
A:I didn't go to school this morning.
B;Neither did i
A:I love the film
B:so do I
A:you like this kind of flower.
B:so i do

none of them go to swim.
Neither do I.
我也不.
All of them go to swim.
So do I.
我也.
Some of them ask me to swim.
So I do.
我就做了.

当前面既有肯定又有否定
或两个谓语时用so it is/was with
也可以用so it is the same with
He likes apples and he doesn't go to school by bus.
So it is with her
而so do I 这一类是前面是肯定的情况也适用于另一主语
They go to school by bus.
So do we.
否定用neither do i
she doesn't go there,neither do i
当表示的确如此用 so i do /am/can
--He is a student.
---so he is

我也不
我也是
因此我这么做
前两个是强调句把neither和so提到句前
