除我之外，还有4名参观者用英语怎么说？

There are 4 other visitors besides me.

There are four visitors except me.
Except me, there are still four visitors.
这里用except，除了。。。之外， 就是要把我除去
假如用besides的话，就是把我算进四个人之中

There are 4 other visitors besides me.

楼上的，一句话你也机译，有没有搞错！！

There are four visitors besides me.
There are four visitors in addition to me.

There are(were) four visitors, except me.

Except for me, there are four other visitors.
