so do he与nor do he
neither do i与either will do的区别

不同的人做同一件事情.要倒装.肯定句用so .谓语与后面的人称和数保持一致.
eg.1. he is a worker, so am i.
2. they are teachers. so is Mike.
3. he goes to school by bike, so does Lucy.
4. he has been to Beijing three times, so do my parents.

同一个人,同一件事情,用正装句.
eg.1. A: Jim is a good boy.
B:so is he.
2. A:Mike goes to work by bus.
B: So he does

否定句用neither 或 nor.谓语与后面的人称和数保持一致.
1. he is not a worker, nor am i /neithe am i
2. he does not like watching Tv, nor do i.
实在不理解就找语法书翻一翻倒装的内容


另外 either will do。是正常语序，意思是 “两个都不”

比如说 Do you like music or movie ? Either will do. I like novel.(你喜欢音乐还是电影？我两个都不喜欢，我喜欢小说)
