Question

I _____ to your party, but I didn't have time. A. would have come B. could have come

这题答案给的是B，但我觉得A更好。请高手详细解释下，谢谢！

Answer 1

你好。你是正确的，应该是A
==If I had had time, I would have come to your party. (这是最好的证明方法，show it to your teacher 。看来，你们老师的变通能力不行，还有他的英语思维不到位，只会根据所给答案上课。) 祝你愉快。

我也这么觉得，但现在我还不能确定。如果确定了咱是对的，我就给你分

放心吧，我是吃英语饭的。Good day to you.

Answer 2

“1.would+have+done”虚拟语气，表示对过去事情的假设，意思是“本来会做”。
I would have told you all about the boy's story, but you didn't ask me. 我本来会告诉你这个小男孩的故事，但是你没有问我。
2.“could+have+done”是虚拟语气，表示对过去事情的假设，意思是本来能够做某事而没有做。
He could have passed the exam, but he was too careless. 本来他能够通过考试，但是他太粗心。

相比之下，选could have come更为确切，需要仔细体会句子的语境。

追问

题干后一句说的是我没时间，也就是客观情况导致不能去。那么用could就有点矛盾吧：“我本能......但没时间”。
用would的话，就是我本来要去的，但是我没时间。感觉这样更通顺。
您怎么看？

Answer 3

看but后面的句子，说明事情已经发生，所以前面半句应该是表示发生过的事情而没有实现的。如果用A,应该是未发生的事情，比如：I would have come to your party if I have time.
