这句英文是对的吗？

不对

I think my English is as poor as your Chinese.

错，应该是：

I think my English is as undesirable as your Chinese.

I don't think my English is good. It's just like your Chinese.

I think my English is as poor as your Chinese.我同意这个,.,

I think my English is not very well as poor as you speaking Chinese. 也同意这个...

不对的 ithink I think my English not very well as your chiness

我的修改意见是
i do not think my english is very well,so as you speak chinese
