《2046》台词
1.只要你自己不放弃，你永远都有机会。When you don’t take “no” for an answer, there is still a chance you’ll get what you want.
2.他一直没有回头，他仿佛坐上一串很长很长的列车，在茫茫夜色中开往朦胧的未来。He didn’t turn back. It’s as if he boarded a very long train headed for a drowsy future through the unfathomable night.
3.如果有一天你可以忘掉过去，记得来找我。Take care. Maybe one day you’ll escape your past. If you do, look for me.
4.爱情是没有替代品的。In love you can’t bring on a substitute.
5.爱情是有时间性的,遇见的太早或太晚都不行 .Love is all a matter of timing.It’s no good meeting the right person too soon or too late.
6.她对你没有反应未必是因为它反映迟钝，也许是因为她对你没有感觉 .Maybe the reason she didn’t answer was not that her reactions were delayed but simply that she didn’t love me.
7.如果你有一个秘密，就到深山里在树上挖个洞，然后对着这个洞说出你心中的秘密，这样秘密就不会被人知道。
If you have a secret, go deep into the mountain and dig a hole in the tree, and then tell the secret in your heart into the hole, so that the secret will not be known.
8.周慕云（梁朝伟独白）
有一个笑话，说阿拉伯数字里的0碰见了8，0就对8说，你以为用一根带子把腰给束起来我就认不出你了么？离开香港几年，我真觉得她从0变作了8！于是，我总极力想把8中间的那根腰带解开…………
There's a joke that says 0 in Arabic numeral meets 8, and 0 says to 8, do you think I can't recognize you by binding your waist with a belt? After leaving Hong Kong for a few years, I really think she has changed from 0 to 8! So, I always try to untie the belt in the middle of 8
有时候我觉得这个世界真的变得很滑稽，以前我写小说是只想给一个人看，现在我写小说是为了不让自己挨饿，给所有无聊的人看；以前两个有欲望有激情的人极力逃避对方，现在两个毫无欲望毫无激情的人却极力想亲近对方…………也许，只有酒，才能重新燃烧我的激情。酒是好东西！
Sometimes I feel that the world really becomes very funny. In the past, I only wanted to write novels for one person. Now I write novels to prevent myself from starving and show them to all boring people. In the past, two people with desire and passion tried to avoid each other, but now two people who have no desire and no passion try to get close to each other Maybe, only wine can rekindle my passion. Wine is a good thing!
我又去了一趟柬埔寨。等我到了那里以后，我才发现，那里的一切也都变了，收藏着我秘密的庙宇已经不复存在，听说是战争的炮火误炸了那个地方…………
I went to Cambodia again. When I got there, I found that everything there had changed. The temple where I kept my secret no longer existed. It was said that the fire of war had mistakenly bombed the place
9.日本人（木村日语独白）
有一棵大树，大树旁边有一个小酒吧，对，那个酒吧叫花样年华，服务员叫小丽，就是染了一头红头发、高鼻梁、大眼睛那个，她老是趴在窗边看小鸟停在大树上…………这儿以前明明有一棵大树的，我记得那时城市里还有树，现在…………好像已经没有植物这个词了。而且，我记得那时世界上还有一种叫爱情的东西，现在好像也没有这个词了…………
There is a big tree. There is a small bar beside the big tree. Yes, the bar is called flower time. The waiter is Xiao Li. She has dyed red hair, high nose and big eyes. She always lies on the window to watch the birds stop on the tree There used to be a big tree here. I remember there were trees in the city at that time. Now There seems to be no word for this plant. Moreover, I remember that there was a kind of thing called love in the world at that time. Now it seems that there is no such word
因为职业的需要，我已经习惯了等待。然而，我却从来没尝试到等一个人等得心痛的感觉！也从来没有试过花美金不是看面额而是用厘米计算的架势。在短短的两个钟头里，一杯啤酒的价钱已经从一厘米美金涨到了三厘米，我已经喝得够慢了，可我还是觉得自己喝得太快了，因为我的朋友还没出现，不知道我还要等他多久！我开始幻想自己是一只很小很小的蚂蚁，因为，以小蚂蚁喝酒的速度，一杯啤酒一定能喝很久很久…………
Because of the needs of my career, I'm used to waiting. However, I have never tried to wait for a person to wait heartache feeling! I've never tried to spend dollars in centimeters instead of face value. In just two hours, the price of a glass of beer has risen from one centimeter to three centimeters. I have drunk slowly enough, but I still feel that I drink too fast, because my friend has not appeared, I don't know how long I have to wait for him! I began to imagine that I was a very small ant, because, with the speed of small ants drinking, a glass of beer must be able to drink for a long time
我终于知道他原来是一个邮差。而且，我也知道了我从来没有关心过的“信”很快就要在这个世界消失了，就像我说过的那样，人们总是会找到多种多样的方法进行沟通的。没有了信，政府就会取消邮局，这个世界也就没有了邮差，所以，这个邮差的身份就像我箱子里的美金一样，很快就要到期作废了。他告诉我，他准备去一个地方碰运气，据说，那个地方的政策会持续不变…………
I finally learned that he turned out to be a postman. What's more, I also know that the "letter" I never cared about will soon disappear in this world. As I said, people will always find a variety of ways to communicate. If there is no letter, the government will cancel the post office, and there will be no postman in the world. Therefore, the identity of this postman, like the US dollar in my box, will soon be expired. He told me that he was going to try his luck in a place where the policy would remain unchanged
10.女机器人（王菲独白）
我曾经试做另外一个梦，然而，我却失败了，我终于明白，我的梦只属于那个离去的人！我也发现，有梦原来是一件痛苦的事！
I tried to dream another dream, but I failed. I finally realized that my dream only belongs to the person who left! I also found that it is a painful thing to have a dream!
那天，他问我，如果他多买一张票，我是不是愿意跟他走，我拒绝了。事实上，我是多么想跟他一起走啊，可不知道为什么，我脑子里的芯片却对我发出了拒绝的指令…………
That day, he asked me if I would like to go with him if he bought an extra ticket. I refused. In fact, how much I want to go with him, but I don't know why, the chip in my brain gave me the order to refuse
