短語 up to speed 意思是了解事情發展的最新情況, 它也可以指一個人能夠勝任某事。


Is Fran up to speed with the project yet? If not, can you please tell her what's been going on since the last meeting?

Brian wasn't very good at using the software to begin with, but now he's up to speed. He just needed to practise.


不要同短語 speed up 搞混,speed up 的意思是提速,加快。


Mike, speed up a bit please! We need to finish this today.
