新概念第一册57课中
In the evening,the children usually do their homework,but this evening,they are not ding their homework.At the moment,they are playing in the garden.请问,at the moment 是否可以换成at that moment 或者 at this moment?

优质解答

at the moment 此刻
(right) at this moment 就现在这一刻 = 比at the moment 更强调“现在这一刻” (前面常常还有个 right).
at that moment 用于过去:
--- Why did you answer the phone when I called an hour ago?
--- I happened to be occupied at that moment.我那会儿恰好有事儿、正忙着呢.
