许多同学在进行英语写作时，很容易受汉语的影响而写错句子，即写出所谓的 Chinlish。这是最常见的错误之一。如：
1. 事实上，这个人年纪很轻。
误：In fact, the man’s age is very young.
正：In fact, the man is very young.
析：中国人常说“年纪轻”，但英语中的 young 本身就有“年纪轻”的意思，它习惯上不再与 age 搭配使用。类似地，汉语说“他年纪很大”，不能译成 His age is very old，而应是 He is very old.
2. 我的工作太忙，我不能来。
误：My work is too busy and I can’t come.
正：I’m too busy and I can’t come.
析：汉语说“工作忙”，实际上是指“人忙”。类似地，要表达汉语中的“我的事情很忙”，英语只需说 I’m busy 就够了，而不能说成 My things are busy.
3. 这个老太太的左眼瞎了。
误：The old woman’s left eye is blind.
正：The old woman is blind in the left eye.
析：汉语中说“眼瞎”，而按英语习惯却要说“人瞎”，瞎在哪儿?瞎在“眼睛”，所以英语中要表达类似意思总是用“人”作主语，而用介词短语引出“瞎”的位置。同样地，要表示“他的左腿是跛的”，不能说成 His left leg is lame, 而应说成 He is lame in his left leg.
4. 他身体很好，很少生病。
误：His body is good / healthy, and seldom falls ill.
正：He’s healthy, and seldom falls ill.
析：汉语说“身体好”，其实是指某人的健康处于一种良好的状态，而绝不是指他的躯体是完好的。
5. 我讨厌周末拥挤的交通。
误：I hate the crowded traffic on weekends.
正：I hate the busy / heavy traffic on weekends.
析：汉语可说“拥挤的交通、街道、房间、商店等”，而英语中虽然可说 crowded streets / rooms, shops 等，但习惯上不说 crowded traffic。
6. 汤姆打了鲍勃的脸。
误：Tom hit Bob’s face.
正：Tom hit Bob in the face.
析：汉语中可以说“打某人的脸”，而英语中必须先说“打某人”再+介词+the+身体的某个部位。又如“打某人的鼻子”译为 hit sb. on the nose.“抓住某人的胳膊”译为 catch sb. by the arm.
想当然错误
有的同学在写作时，常将一些似是而非的东西想当然乱用，不注意语言的准确性和地道性。
1. 我说两个小时的时候，那是包括了吃饭的时间。
误：When I say two hours, which includes the time for eating.
正：When I say two hours, that includes the time for eating.
析：许多同学往往想当然地认为在逗号后面总是用 which 引导定语从句，而不用 that。其实，本句中的 that includes the time for eating 不是定语从句，而是主句(that 用作主句主语)，其前的 when I say two hours 为状语从句。
2. 你应该更注意练习你的英语口语。
误：You should pay more attention to practise your spoken English.
正：You should pay more attention to practising your spoken English.
析：有的同学们认为 to 后总是接动词原形，构成不定式。其实，此句中的 to 不是不定式符号，而是介词，所以其后的动词要用原形。
3. 几年前，对大多数中国人来说，在家里有一台电脑的想法还是不大现实的。
误：Just a few years ago, the idea to have a computer in one"s home seemed very difficult for most Chinese.
正：Just a few years ago, the idea of having a computer in one"s home seemed very difficult for most Chinese.
析：许多同学认为表示做某事就用动词不定式，这要根据具体情况来定。idea 后面要用of 短语说明 idea 的内容。
4. 尽管他只有十六岁，但是他已经学会用英语和外国人交谈了。
误：Although he is a boy of sixteen, but he has learned to talk with the foreigners in English.
正：Although he is a boy of sixteen, he has learned to talk with the foreigners in English.
正：He is a boy of sixteen, but he has learned to talk with the foreigners in English.
析：许多同学往往认为“虽然„但是”是关联词组。但 although 是从属连词，而 but 为并列连词，故不能同时出现在同一句中。类似的还有 because 和 so，也不能连用。
5. 他迟到的原因是因为他没赶上早班车。
误：The reason why he was late is because he didn’t catch the early bus.
正：The reason why he was late is that he didn’t catch the early bus.
析：许多同学认为“因为”表原因就用 because，但在此句 The reason why„is that 中 that引导表语从句，无实际意义。
6. 他说他将尽最大努力学好英语。
误：He said he would do what he could learn English well.
正：He said he would do what he could to learn English well.
正：He said he would do / try his best to learn English well.
析：情态动词后只能跟动词原形。于是有的同学就出现了误句。实际上，此句中“学好英语”是“尽最大努力”的目的状语，应该用不定式。
思维定势错误
有的同学不能灵活地运用所学知识进行表达，而是凭印象观念，结果写错句子。
1. 我永远不会忘记我们一起度过的日子。
误：I’ll never forget the days when we spent together. 正：I’ll never forget the days which / that we spent together. 析：有的同学记住了定语从句的规则，当先行词指时间时，关系词用 when，而没用考虑它在定语从句中做什么成分。此句中的 spent 是及物动词，应由 which 或 that 替代 the days作它的宾语。
2. 炎日下没有比一杯冷饮更让人愉悦的了。
误：Few pleasures can equal those of a cool drink on a hot day. 正：Few pleasures can equal that of a cool drink on a hot day. 析：有的同学只知道用 that 指代前面的单数或不可数名词，用 those 指代复数名词。殊不知，此句中 Few pleasures 和 a cool drink 这种乐趣相比，因此应该看成单数概念。
3. 他从上一星期二一直病着。
误：He has been ill from last Tuesday.
正：He has been ill since last Tuesday.
析：有的同学认为“从„”译为from, 如：从7点到9点from7 to 9;从家到学校from home to school. 但在现在完成式中却用 since. 4. 那个丢失的孩子最后一次被看见在河边玩。
误：The missing boy was last seen to play near the river. 正：The missing boy was last seen playing near the river. 析：有的同学只记得：在主动语态中感官动词后面不带 to,而变为被动语态时则必须带to. 因此没有具体分析，此句是考查感官动词后接现在分词表示动态情景。“看见某人正在做某事”译为 see sb. doing sth.,变为被动语态为 sb. is seen doing sth. 5. 他很少上学迟到，如果有的话，也很少。
误：He is seldom, if any , late for school. 正：He is seldom, if ever, late for school. 析：有的同学知道 any 用于 if 引导的条件状语从句中，但此句是一个省略句，完整的句子为 He is seldom, if he has ever been , late for school. 用 if ever 表示如果曾经迟到过的话。
6. 他把雨伞忘在火车上了。
误：He has forgot his umbrella on the train. 正：He has left his umbrella on the train. 析：“遗忘”译为 forget 或 leave.但二者是由区别的：leave 多于表示场所的地点状语连用，而 forget 通常不与表场所的地点状语连用。外出时把东西忘记在家里的时候通常用forget. 如：“我忘了带驾驶证”译为 I’ve forgot the driver’s license.
成分残缺错误
许多同学在进行英语写作时，通常不考虑句子的完整性而写出一些成分残缺的句子。
1. 他的笔头英语不错，但口语不行。
误：His written English is good, but not good at spoken English.
正：His written English is good, but his spoken English is not good.
正：He is good at written English, but not good at spoken English.
析：误句中 but 后的句子缺适当的主语，因为 good at spoken English 的主语应是“他”，而不是 his written English。
2. 英语很有趣，我的确很喜欢。
误：English is very interesting, and I really like very much.
正：English is very interesting, and I really like it very much.
析：like 是及物动词，其后通常应有宾语。
3. 别怕，我们会帮你的。
误：Don’t afraid; we’ll help you.
正：Don’t be afraid; we’ll help you.
析：误句谓语不完整，因为 afraid 是形容词，不是动词，不能单独作谓语，必须和连系动词一起构成谓语。当然，若说成 Don’t fear，则完全可以。
4.住在我隔壁的李明是个医生。
误：Li Ming, lives next to me, is a doctor.
正：Li Ming, who lives next to me, is a doctor.
正：Li Ming, living next to me, is a doctor.
析：误句中定语成分不完整。定语从句是一个完整的句子，当先行词指人且关系代词在从句中作主语时要用 that 或 who。也可用现在分词短语作后置定语。
5. 你介意我问你一个问题吗?
误：Do you mind I ask you a question?
正：Do you mind if I ask you a question?
正：Do you mind my asking you a question?
析：误句中的主句和从句之间缺少连接词。也可以用动名词短语作 mind 的宾语。
6. 他考试及格了使他妈妈很高兴。
误：He passed the exam made his mother very happy.
正：That he passed the exam made his mother very happy.
正：He passed the exam, which made his mother very happy.
析：误句中的主语应该是由主语从句来承担的。that 引导主语从句，不做成分，无实际意义，但不能省略。也可以用非限定性定语从句。
结构搭配错误
有的同学在写作时，常常把一些固定词组、习惯用语和固定句型错误搭配，结果写出来的句子让人看不懂。
1. 你愿意帮我忙吗? 误：Will you give me a favour?
正：Will you do me a favour? 析：“帮某人一个忙”、“给某人恩惠”应是 do sb. a favour. 2. 在回家的路上，史密斯夫人的钱包被抢了。
误：Mrs. Smith’s wallet was robbed from her on her way home. 正：Mrs. Smith’s wallet was stolen from her on her way home. 正：Mrs. Smith’s wallet was robbed of her on her way home. 析：“抢某人某物”译为 steal +某物+from+某人或场所，或 rob+人或场所+of +某物。
3. 你认为工程师的演讲怎么样? 误：How do you think of the speech made by the engineer? 正：What do you think of the speech made by the engineer? 析：本句的错误在于有同学对 what „think of 的结构概念模糊加上母语的干扰而造成的。What 在这一结构中作 think 的宾语。what do you think of„还可以说 How do you like„? How 在句子中是疑问副词，作状语。
4. 这个问题很难懂。
误：The question is hard to be understood. 正：The question is hard to understand. 析：在“主语+be+形容词+不定式”的句式结构中，主语是不定式的逻辑宾语，不定式用主动形式表示被动意义。又如：The man is hard to work with.其中，与不定式习惯搭配或根据表达需要的介词不能省略。
5. 她有如此好的一位父亲，以致于我们都很羡慕她。
误：She has a so good father that we all admire her. 正：She has so good a father that we all admire her. 正：She has such a good father that we all admire her. 析：so 是副词，用来修饰形容词或副词，常用于 so+ adj. / adv.+ that„句型中，表示“如此„以致于”。在单数可数名词前可用 so+ adj.+ a+名词+that„句型，相当于 such +a +adj. + 单数名词+ that 结构。
6. 他可不是那种先想到自己后想到别人的人。
误：It’s not like him of thinking of himself before thinking of others. 正：It’s not like him to think of himself before thinking of others. 析：表示“某人(恰恰)就是„这个样子”，用 It’s (just) like sb. to do sth.说明赞成或不满。若用否定式则表示怀疑。
