Would 是常见的情态动词之一，我们对它的印象大部分是后面要加动词原形，然而它的用法之丰富不亚于介词。虽然它通常以 will 的过去式身份出现在我们的日常生活中，然而它的实际用法远远不止这个。越深入学习 would，你就会越爱上它。 一、would 用来讨论过去1. would 用作 will 或 be going to 的过去式，意为“会，将，将会”，例如：Even as a boy, he knew that he would succeed in life.他小时候就知道自己会成功。I thought it would rain so I brought my umbrella.我以为将会下雨，所以带了伞。在直接引语中用 will，改成间接引语时常用 would，例如： He said he would be here at eight o'clock.他说他将在八点钟到达这里。
They said that they wouldn't see us at the party.他们说他们将不会在聚会上见到我们。
2. 表示愿意，意为“愿，要，会，定要”，常用于否定句，例如：His mother wouldn't let him go to the party.他妈妈不让他去参加聚会。He wanted a divorce but his wife would not agree.他想离婚，但他妻子不同意。My car wouldn't start this morning.今天早晨我的汽车怎么也发动不起来。3. 表示过去常见的情况或习惯，意为“总是，老是”，相当于 used to；但 would 有时也用来表示某些习惯是极端的，此时常与频度副词 always 连用，例如：When my parents were away, my grandmother would take care of me.我父母外出的时候，总是祖母照看我。He'd always be the first to offer to help.他总是第一个主动提出帮忙。He would always send her strange birthday gifts.他总是送她奇怪的生日礼物。注意，此时的 would 不能用来讨论过去的事实或状态，例如： 我小时候常住在墨尔本。I used to live in Melbourne when I was a kid. (正确)I would live in Melbourne when I was a kid. (错误)二、would 用来讨论过去的将来 基于过去的某一时间点，would 用来讨论此时间点后的将来，例如：When I was young I thought that I would be really tall in years to come.当我年轻的时候，我以为在未来的岁月里我会变得很高。In London she met the man that she would marry one day.在伦敦她遇到了她有朝一日要嫁的人。
三、would 表请求Would 和 will 都可以表请求，但是 would 更正式、礼貌和委婉，例如： 你能帮帮我吗？Would you please help me? (更礼貌)Will you please help me?请你给我开门好吗？Would you open the door for me, please? (更礼貌)Will you open the door for me, please?四、would（或'd）用于条件句 1. 用于第二类条件句，用来谈论与将来相反或现在不可能的事情，例如：If I won the lottery, I would buy a big house.如果我中了彩票，我会买一幢大房子。If I were you, I wouldn't go out with that man.如果我是你的话，我就不会和那个男人约会。2. 用于第三类条件句，用来谈论过去，描述一个没有发生的情况，并想象这种情况的结果，例如：If we had left earlier, we would have been able to stop off for a coffee on the way.如果我们早点走的话，我们就可以中途停下来喝杯咖啡了。If the train hadn't been late, we would have arrived on time.如果火车没有晚点，我们就会准时到达了。五、would 与 wish 连用Wish + (that) + would + 不带 to 不定式，通常不用来谈论与我们自己有关的事或没人能改变的事，表达不耐烦或不满等情绪，例如：I wish that he wouldn't smoke so much.我希望他不要抽那么多烟。I wish you would come to see me more often.我希望你能经常来看我。六、固定搭配 1. Would 常与 like，love，prefer，rather 或 mind 等连用，表达想要什么或想做什么等，此时的 would 不能用 will 代替，例如：I would like some coffee.我想要些咖啡。I would love to play for England again.我很乐意再次为英格兰队效力。We would prefer to leave immediately.我们宁愿马上离开。She would rather go to the cinema.她宁愿去看电影。Would you mind helping me?你介意帮我吗？2. 通常在疑问句中与 like 连用，表示礼貌地给予或邀请，例如：Would you like a sandwich?您来一个三明治好吗？Would you like to come with us?你想不想和我们一块儿去？七、would 和 hadWould 和 had 都可以缩写为“'d”，但是 would 后面跟的是不带 to 不定式（动词原形），而 had 后面跟的是过去分词或带 to 不定式。
