请教一个初中英语题.

It will be my first time to go to Beijing next month.

It will be my first time to go to Beijing next month.

next month 下个月，还未发生，用将来时

first time to do sth.

It (will be) my first time (to go to)Beijing next month.

事情发生在将来，应用一般将来时，即：
1.Be going to...(物作主语sth.)
2.will be的形式，其中will表将来（人作主语sb.)

该句应译为：下个月我将第一次去北京。

I(will )(be)my first time( to)(go)Beijing next month.

括号1 、2 根据next month判断是将来时
括号3、4 根据句型the/one's first time to do sth.判断。是固定句。

It will be my first time to go to Beijing next month.
固定用法：it be one's first time to do sth
由next month 可知是将来时，所以用will

will be ,to go
