直到一切准备好,我们才会举行运动会用英语怎么说?

用not...until...句型翻译如下：
We won't hold the sports meeting until everything is ready.
如果用倒装句型,则为：
Not until everything is ready will we hold the sports meeting.
如果再结合强调句型,则为：
It is not until everything is ready that we will hold the sports meeting.

it is not until all is ready will we hold the sports meeting .
