比如我想说我从来没见过那个地方有这么多虫子,但现在我不仅见到了,我还在这里.I had never thought that there would be such a terrible place where there are so many bugs.But now,I not only have seen one,but also am in one.这句话应该是错的,但是第二句应该怎么说才对?

I have never thought that there could exist such a terrible place where there are so many bugs.But now,I have not only seen them, but also been to here....

I never thought that there would be such a terrible place where there were so many bugs. But now,I have not only seen one, but also remained here.

应该用现在完成时：I have never thought that there could exist such a terrible place where there are so many bugs.But now,I have not only seen one, but also been there.

I never thought that there would be such a terrible place where there are so many bugs. But now, I not only have seen one, but also am living in the middle of such a place.
这样说就不会引起歧义了。
