日常生活中常见的错误翻译,让我们哭笑不得
日常生活中常见的错误翻译，让我们哭笑不得对于中国人来说，我们在说英语的时候，往往是先用中文思考，然后再想用英文怎么说。
如果是直接翻译而不参考习惯表达，我们很容易闹出各种笑话。
下面给大家盘点一些常见的翻译错误，阅读时请自行脑补各种画面。
邀请妹子参加聚会：中文：你愿意参加我们的聚会吗?“神”翻译：Would you like to join our party?（来，亲！加入我党吧！我们是XX主义接班人……）推荐翻译：Would you like to come to our party?画外音：join多指加入某个组织或者党派，party除了表示聚会，还可以表示党派。
党果然把你教育地很先进，遇到一个外国妹子，一上来就让人家入党。
但是这样真的好么？！会把妹子吓跑的啦！英语不好，妹子会跑！T.T在妹子面前谦虚一下：中文：我的舞跳得不好。
“神”翻译：I don’t dance well.（我就不好好跳舞！你咬我呀！你咬我呀！）推荐翻译：I am not a very good dancer.画外音：导演，说好的谦虚呢？这样贱贱的台词真的好么？中文：别对我期望太高。
“神”翻译：Don't expect me too much.（别老盼着我，太想我是不对的哟！）推荐翻译：Don't expect too much of me.画外音：来人，快把这个自恋狂拖走。
描述自己的住处：中文：我的屋子比较窄，但是很整洁。
“神”翻译：My room is narrow,but it is very tidy.（我的房间可是很细很细的哟！）推荐翻译：My room is small,but it is very tidy.画外音：你是毛毛虫吗？住细长细长的房间？难道是住走廊过道？妹子跟了你，得哭晕在厕所里。
妹子病了，关心一下：中文：你生病了，你要多喝白开水。
“神”翻译：You are sick.You should drink more white boiled water.（汉子：亲爱滴，你病了，多喝白色的开水哟！妹子：啊！偶找不到白色的开水！偶是不是好不了了！偶是不是要死了！嘤嘤嘤……）推荐翻译：You are sick.You should drink more plain boiled water.画外音：白开水指“水中没有添加其它的东西”，不是白色的水。

Unit4课文翻译素材-高中英语牛津译林版(2020)选修第二册
高中英语译林版选修二课文翻译（原文+中文翻译）Unit 4 Law and order法律与秩序Reading The rules of law 法治Have you ever wondered when and where the law originated? Around 12,000 years ago in the Middle East, small permanent farming communities were established,changing traditional nomadic hunter-gatherer lifestyles. Different groups were closely living together and dealing with unfamiliar behaviours, beliefs and attitudes. To prevent chaos and resolve conflicts, the rules of conduct and consequences for unacceptable behaviours were created. Hence, the concept of law was born.你有没有想过法律起源于何时何地?大约1.2 万年前，中东地区建立了小型永久性农业社区，改变了传统的游牧狩猎采集生活方式。
不同的群体紧密地生活在一起，处理不熟悉的行为、信仰和态度。
为了防止混乱和解决冲突，制定了行为规则和不可接受行为的后果。
因此，法律的概念诞生了。
Many ancient civilizations arose in the Middle East, so it is not surprising that law codes first appeared there. The oldest discovered, the Code of Ur-Nammu, dates back to about 4,000 years ago. The code presented laws in the cause -and-effect format, a style used in nearly all later codes. Another one discovered, the Code of Hammurabi, was composed around 300 years later, which is one of the longest, best-organized and best-preserved legal texts. This code was among the first to implement the concept “innocent until proven guilty”. Both codes have features in common. For instance, they treated a variety of matters,but often ignored some important rules, because such rules were deeply grounded in custom.许多古老的文明都起源于中东，因此法典最早出现在那里也就不足为奇了。

Section A --- 3aBus Driver and Passengers Save an Old ManAt 9:00 a.m. yesterday, bus No. 26 was going along Zhonghua Road when the driver saw an old man lying on the side of the road. A woman next to him was shouting for help.The bus driver, 24-year-old Wang Ping, stopped the bus without thinking twice. He got offand asked the woman what happened. She said that the man had a heart problem and should go to the hospital. Mr. Wang knew he had to act quickly. He told the passengers that he must take the man to the hospital. He expected most or all of the passengers to get off and wait for the next bus. But to his surprise, they all agreed to go with him. Some passengers helped Mr. Wang to move the man onto the bus.Thanks to Mr. Wang and the passengers, the man was saved by the doctors in time. “It's sad that many people don't want to help others because they don't want any trouble,” says one passenger. “But the driver didn't think about himself. He only thought about saving a life.”【中文翻译】公交车司机和乘客救了一位老人昨天上午九点，26路公交车正沿着中华路行驶，这时司机看到路边躺着一位老人。
