if you don't go there tomorrow,i ____(not),either

If you don't go there tomorrow,I will not （ go there ),either.这个是考查主将从现原则和省略原则相结合的一道题.
1.主将从现原则：在时间,条件,方式等状语从句中,从句用一般现在时表示将来,主句用一般将来时.
E.g.If it rains tomorrow,we will not go climbing.
When he comes,I will prepare a good meal for him.
2.省略的现象很复杂.这里就题论题.因为题中前半句已经有了"go there tomorrow",所以在主句中再一次出现同样的谓语动词时,就可以省略.
E.g.--- He often goes to the park after supper.
--- Me.too ( =I often go to the park after supper too.) 至于为什么用Me,不用I ,这是交际用语中的习惯.习惯用宾格代替主格.
E.g.--- Who is there?--- Me.
