我们之间还是有太多的不了解.用英语怎么说?

We don't know much about each other.

There are still some not understanding between us.

there are still exist incomprehensions between us.

we are not well-acquainted enough~
相信我，这个翻译是最好的~

if there are a lot of incomprehensions between us~

We don't know much about each other. 这个才是最好的。
there are still exist incomprehensions between us. 这样之类的翻译只是按照你的中文意思翻译的，外国人不是那样说的。
