两者都可用!你可以在这里使用任何东西。 At that time是指上面曾经提到过的时间,也用来区分任何两个不同的时区。 At the time指事情发生的时间!示例: People were confused about it at that time. = People were confused about it at the time. (当时人们对此有点困惑。) 例子: At the time of the exam, I was well prepared for it. ( At that time, I was well prepared for the exam. (当时我已经为考试做好了充分的准备。)
