&p&&b&没人来说说“The”的使用么！定冠词the是英语中出现频率最高的单词。&/b&最常用又陌生的语法点。
往往使用最频繁的最容易出错。&/p&&p&&br&&/p&&p&哪里要加the，哪里不要加the，是不同段位英语学习者所面临的问题。&b&仍然记得我的剑桥导师说，能否恰到好处地使用“the”的可以一下子反映出一个人的英语写作水平。&/b&&/p&&p&&br&&/p&&p&下面和大家分享雅思官方出品方 British Council （英国文化教育协会）对 The的用法的官方解读，简单易懂。&/p&&p&&b&The 的使用&/b& &/p&&p&&br&&/p&&ol&&li&&b&我们在一个单词使用定冠词the是因为我们相信读者或听者知道所指事物具体是什么。&/b&&/li&&/ol&&p&&b&因为这一事物在世界上是独一无二的。&/b&&/p&&p&&b&比如：The Pope&/b& is visiting Russia.&br&&br&&b&The moon&/b& is very bright tonight.&/p&&p&&br&&/p&&p&&b&2. 或者说这一事物所具备的特征在那个特定情景中是独一无二的。&/b&&/p&&p&&b&例如在形容词最高级前加定冠词&/b&&/p&&p&&br&&/p&&p&He is &b&the tallest boy&/b& in the class.&br&&br&It is &b&the oldest building&/b& in the town.&/p&&p&&br&&/p&&p&&b&3. 这一事物在上文中已经提到。&/b&&/p&&p&A woman who fell 10 metres from High Peak was lifted to safety by a helicopter. &b&The woman&/b& fell while climbing.&br&&br&The rescue is the latest in a series of incidents on High Peak. In January last year two men walking on &b&the peak&/b& were killed in a fall. &/p&&p&&br&&/p&&p&&b&4. 一个名词前有定冠词代表这一事物的集群&/b&&/p&&p&The wolf is not really a dangerous animal (= Wolves are not really dangerous animals)&br&&br&The kangaroo is found only in Australia (= Kangaroos are found only in Australia)&/p&&p&&br&&/p&&p&&b&5. 指代某个系统或某种服务&/b&&/p&&p&How long does it take on &b&the train&/b&?&br&&br&I heard it on &b&the radio&/b&.&br&&br&You should tell &b&the police&/b&.&/p&&p&&br&&/p&&p&&b&6. 放在乐器前&/b&&/p&&p&Joe plays the piano really well.(= Joe can play any piano)&br&&br&She is learning the guitar.(= She is learning to play any guitar)&/p&&p&&br&&/p&&p&&b&7. 放在个别形容词之前指代某个群体&/b&&/p&&p&Life can be very hard for &b&the poor&/b&.&br&&br&I think &b&the rich&/b& should pay more taxes.&br&&br&She works for a group to help &b&the disabled&/b&.&/p&&p&&br&&/p&&p&&b&8. 一般不会在人名、事物名称前加定冠词The&/b&&/p&&p&&b&不过也存在一些特殊情况，&/b&&/p&&p&&b&例如，国家名中包括kingdom, states, republic，国家名为复数，&/b&&/p&&p&&b&描述地理特征时，如山区，岛屿群，河流，大海，运河&/b&&/p&&p&&b&报刊杂志，世界闻名的建筑物或艺术品&/b&&/p&&p&&b&组织，宾馆酒吧餐厅的名称&/b&&/p&&p&&b&家族名称&/b&&/p&&p&We do not normally use the definite article with names:&/p&&p&William Shakespeare wrote Hamlet.&br&Paris is the capital of France.&br&Iran is in Asia.&/p&&p&But we do use the definite article with:&/p&&p&o &b&countries&/b& whose names include words like &b&&i&kingdom&/i&&/b&, &b&&i&states&/i&&/b& or &b&&i&republic&/i&&/b&:&/p&&p&the United K the Kingdom of N the United S the People’s Republic of China.&/p&&p&o &b&countries&/b& which have &b&plural nouns&/b& as their names:&/p&&p&the N the Philippines&/p&&p&o &b&geographical features&/b&, such as mountain ranges, groups of islands, rivers, seas, oceans and canals:&/p&&p&the H the C the A the Atlantic O the A the Panama Canal.&/p&&p&o &b&newspapers&/b&:&/p&&p&The T The Washington Post&/p&&p&o well known &b&buildings&/b& or &b&works of art&/b&:&/p&&p&the Empire State B the Taj M the Mona L the Sunflowers&/p&&p&o &b&organisations&/b&:&/p&&p&the United N the Seamen’s Union&/p&&p&o &b&hotels&/b&, &b&pubs&/b& and &b&restaurants&/b&*:&/p&&p&the R the Ritz H the King’s H the Déjà Vu&/p&&p&*Note: We do not use the definite article if the name of the hotel or restaurant is the name of the owner, e.g.,Brown’s; Brown’s H Morel’s; Morel’s Restaurant, etc.&/p&&p&o &b&families&/b&:&/p&&p&the O the Jacksons&/p&&p&&br&&/p&&p&&br&&/p&&p&&b&你会使用“The“了么？&/b&&/p&&p&&b&&i&如果你对我关于语言学习方面回答感兴趣，欢迎关注：&/i&&/b&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&哪些英语单词我们经常用错？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&每天坚持英语学习为什么还是学不好？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&为什么很多人学了很多年英语，却不能跟外国人简单交流？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&哪些英语用法是普通中国学生最生疏的？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&有哪些出国后才发现的以前对英语的错误理解？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&《经济学人》杂志好在哪？&/a&&/p&&p&&b&方法论：&/b&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&学西班牙语的人，你们是怎么走过来的？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&英语连读有哪些规则跟变音技巧呢？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&练习英语口语的方法？&/a&&/p&&p&&b&学术英语：&/b&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&如何提高学术方面的英语水平，尤其是论文写作？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&在英语学习过程中，有哪些书籍让你醍醐灌顶？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&英语原版语法书，有哪些推荐的？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&怎样提高presentation能力？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&如何提高雅思写作成绩？&/a&&/p&&p&&a href=&https://www.zhihu.com/question//answer/& class=&internal&&雅思口语怎么备考？&/a&&/p&&blockquote&更多语言学习笔记见微信公众号 潇峰学长，ID：xuxiaofeng600。&br&回复 语言学习笔记

I'll come to find you& （你在哪里？ 我来找你），简直无语。这里用 see好点Where are you? I'll come to see you.&/blockquote&&ul&&li&&b&推荐说法 &/b&If you have any question, please come to me directly.&br&&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&ul&&li&&b&我明天给你反馈。&br&&/b&&/li&&li&&b&I’ll&br&feedback you tomorrow.&/b& &/li&&/ul&&blockquote&这是很多做外贸或者做销售的回复客户邮件时的误用，feedback只能做名词。在《How google works》里的学到用词组feed back. 我也听过一个老外口头上也说feedback you，我好奇地问他feedback可以这样用吗，他马上就承认是错的^_^，偷懒而已。&/blockquote&&ul&&li&&b&推荐说法一：&/b&I’ll&br&&b&give you feedback&/b& tomorrow.&br&&/li&&li&&b&推荐说法二：&/b&I’ll&br&&b&feed you back&/b& tomorrow.&br&&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&ul&&li&&b&星期五行吗？&br&&/b&&/li&&li&&b&Is&br&Friday OK for you?&/b& &/li&&/ul&&blockquote&OK for you = good for you 对某人有好处，属于乱套介词。&/blockquote&&ul&&li&&b&推荐说法：&/b&Is&br&Friday OK with you?&br&&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&ul&&li&&b&只要你对价格满意就成交。&br&&/b&&/li&&li&&b&Only&br&if you are happy with the price, it’s a deal.&/b& &/li&&/ul&&blockquote&我发现很多人不会用as long as 这个非常常见的固定搭配来表示“只要.....就”，用汉英词典查出来的都是 only if，但是only if 表示 &仅....情况下”，比如，&只有水存在的情况下才有生命&，就是only if there is water。&br&&/blockquote&&ul&&li&&b&推荐用法&/b& As&br&long as you are happy with the price,
it’s a deal.&br&&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&ul&&li&&b&-

You&br&are impatient/unreasonable&/b&&/p&&blockquote&英文中如果这样说，会得罪很多人，因为你用一个 are 就把别人完全说死了，正常的说法是用being，这样表示某时某刻这个人处于的状态,不表示你把他彻底说死。&/blockquote&&ul&&li&&b&推荐说法： &/b&You are being impatient/unreasonable&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&ul&&li&&b&这是我的照片（本人照片）&br&&/b&&/li&&li&&b&This is my picture&/b& &/li&&/ul&&blockquote&吐槽的是，这是初中英文知识，现在大把人还用错。my picture只是代表这个照片是你的，比如你手机里的照片都是你的。a picture of me才是这是我&b&个人&/b&的照片，我在照片里。&/blockquote&&ul&&li&&b&推荐用法&/b&： This is a picture of me.&br&&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&ul&&li&&b&你来自哪里？&/b& &/li&&li&&b&Where are you come from?&/b& &/li&&/ul&&p&&br&&/p&&blockquote&这个我不想说了，很多人明明写的时候知道是错的，说的时候偏偏要这样说。&/blockquote&&p&&br&&/p&&ul&&li&&b&应该没什么问题&br&&/b&&/li&&li&&b&There should have no problem.&/b& &/li&&/ul&&blockquote&又是套用中文的思维“有”
已经表示了“有”（存在）的概念了&br&&/blockquote&&ul&&li&&b&推荐用法：&/b&There should be no problem.&br&&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&ul&&li&&b&他只在这里待了两天&br&&/b&&/li&&li&&b&He only stayed here for two days.&/b& &/li&&/ul&&p&&br&&/p&&blockquote&only的误用也非常普遍，only必须紧挨着需要修饰的词，而中文的“只”通常和动词连在一起,这时要看情况到底“只”修饰哪个部分。&br&&/blockquote&&ul&&li&&b&推荐说法：&/b&He stayed here for only two days&br&&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&ul&&li&&b&一张申请表只能填一个人的信息&br&&/b&&/li&&li&&b&One&br&application form is only allowed to fill in one person’s information.&/b&&/li&&/ul&&p&&br&&/p&&blockquote&这里除了only用错了之外，也是按照中文的顺序一步一步翻译出来的。fill的主语必须是人（要人才可以fill)，比如 I fill the information in the form.&/blockquote&&ul&&li&&b&推荐说法：&/b&Only&br&one person’s information is allowed to be filled in an application form&br&&/li&&/ul&&p&&br&&/p&&p&&br&&/p&&p&&br&&/p&&h2&&b&干货来了&/b&&/h2&&ul&&li&&b&把重量超出规格上限的产品挑出来&br&&/b&&/li&&li&&b&Please pick out the parts that are heavier than the upper limit&/b&&/li&&li&&b&Please pick out the parts whose weights are greater than the upper limit.&/b&&/li&&/ul&&blockquote&这种说法也不能说错，只是不简洁，很啰嗦，老外通常不会这么说。用一些 前缀 over（过多）, under（过少）, mis（误），out（超出） 加在动词或者名词前&b&（字典上没有没关系，你可以自创）&/b&，可以简洁表达相应的意思。比如overestimate(高估）, underestimate（低估），misjudge(误判），outperform(比...强）。特别是out前缀，非常好用，我在网上找到了一篇关于out前缀的单词汇总分享给大家，详见结尾链接。&br&- 这条信息我看错了&br&- I &b&misread&/b& your email&br&- 他没有告诉我正确的信息，所以我犯错了。&br&- I made a mistake because of being &b&misinformed&/b&.&br&- 这个产品做错了&br&- The product was manufactured in a wrong way.(啰嗦）&br&- The product was &b&mismanufactured&/b&(简洁）&br&- 我的衣服已经穿不下了&br&- I &b&outgrew&/b& my clothes.&br&- 这个行业比其他行业成长快&br&- This industry &b&outgrew&/b& the rest.&br&- 十月的销售业绩比九月的要好&br&&br&- October's sales performance is better than September（啰嗦）&br&- October's sales &b&outperformed&/b& September.(简洁) （有知友指出这里应该是outperformed that of September,我也推荐这样写。我原文之所以那样写是因为看到新闻上经常省略&a href=&https://link.zhihu.com/?target=http%3A//www.marketwatch.com/story/chinas-economy-may-outperform-the-us-in-2016-says-strategists-& class=& wrap external& target=&_blank& rel=&nofollow noreferrer&&China’s economy may outperform the U.S. in 2016, says strategists&/a&）&br&- 我奶奶比爷爷活得长5年&br&- My&br&grandpa lived 5 years longer than my grandpa（啰嗦）&br&&br&- My grandma &b&outlived&/b& my grandpa by 5 years(简洁)&br&- 我们的产品定价过高&br&- Our product was too expensive when pricing(啰嗦）&br&- Our product was &b&overpriced&/b&.（简洁）&br&- 产能过剩 over capacity
