there and back

​

adding together the distance or time to and from a particular place

往返

It was 20 miles there and back.

到那儿往返共20英里。

I planned to get there and back in the same day.

我本想一天内往返。

And they can't get there and back without a car which is a bit revolutionary for Mr Carson.

而且他们来回都得坐汽车，这对卡森先生就太新潮了

to……and back

It's a long day up to London and back again.

一日往返伦敦肯定很辛苦。
