would是什么时态

would是过去时态的虚拟语气，在英语中，would用于表示与现在或未来事实相反的假设，或者用于表达强烈的愿望、建议、要求等。

1、If I had more money, I would travel the world.(如果我有更多的钱，我会周游世界。)

2、I suggested that she go to bed early, but she wouldn't listen.(我建议她早点睡觉，但她不听。)

3、He asked me to help him with his homework, but I wouldn't know how.(他请我帮他做作业，但我不知道怎么做。)

通过使用would,我们可以在陈述一个与现实相反的假设时，更加委婉地表达自己的观点或意愿。
