I had a suspicion that somebody had come in and changed the ornaments on the piano around.我怀疑有人进来挪动了钢琴上面装饰物的位置。

We can change people around. They don't always have to do the same job.我们可以进行人员调换, 他们不用一直干同样的工作。

We'll change around at the end of this over and you can bat and I'll bowl.打完这场咱们换一下位置, 你来击球我来投。
