"马上去做" 英文怎么翻译？

do it right now

do it at once

应该根据语境上下文来翻译，一般英美人会用come on 来表达此意，不过在有些情况下会表示强调的时候用do it right now也可以

Do it now(right now)!

I'll is back in a jiffy.
我马上去做。
We will do it in a jiffy.
我们马上去做。
With these conditions present, we can start work there at once.
有这些条件，就能马上去做工作。
I'll do it in short meter.
我马上就做。

get down to business right away
do it right away/right now
do it now
