新概念第一课语法问题

Question

The hunt went on for several weeks, the puma was not caught. 为什么后句不是用the puma had not been caught?

Answer 1

这里是保持一般过去时上下文一致。除非有突发状况，英语才考虑时态改变。追问

请问一下这句， the experts were now fully convinced that the animal was a puma , but where had it come from? 为什么后句不保持一致，用where did it come from?

追答

这个动物来自哪里，先于专家的动作被说服，因此是过去的过去，即过去完成时。这里对时间的先后顺序进行了强调。

采纳支持下，亲。
