)—Why didn't you buy the gold ring?答案选a 为什么不选c

这是表示与过去事实相反虚拟语气的动词形式,完整的句子是：I would have (bought the gold ring),but I didn't。。。等于I would have (bought the gold ring) if I had had the money。 再问： ?为什么不用C？不可以说我想买但是没钱，would like to是一般现在时的“我想要做某事 再答： 这是陈述过去的一个事实而非表达现在的一个主观愿望。 下面这个语境就可以用 would like to --Would you be so kind as to go there with me? --I'd like to, but I am too busy。
