“我没有。。。” 翻译成英语是 I have no sth 还是 I don't have sth ？？

I have no...和 I don't have ...都可以(注意如果要翻译我什么都没有时, have后面只能接anything 或者nothing,something是接在肯定句后面的 不能接在否定句后)

都可以的，但是要地道一点呢：
I have nothing
或 I do have nothig(do 表示强调）

一般用后者。否定提前嘛。

Both right。都对

I have no
I dont have

I have nothing或I don't have anything.
