㈠ 常见英语写作错误
1.结构不平行例：I was able to raise my TOEFL score by studying hard and I read lots of books.当使用连词将一系列的单词联接起来的时候，应当使用词性相同或同一类型的短语。
2.不知所云例：Many companies began using computers mouth.
3.段落过长，不分段主语与动词一致问题She are a good friend of mine that I has known for a long time.主语和动词在数方面不一致。
4.句子别扭We heated the soup in the microwave for too long and the shape of the container changed.措辞过长或不清。换言之，句子显得滑稽可笑。
5.不要使用缩写在正式的写作中不要使用缩写形式(can't，don't，it's，we'll，they've等等)，而应当使用单词的完整形式(cannot，do not，it is，we will，they have等等)。
6.关联词语重复Since I want to go to a good school, therefore I am trying to raise my test scores.不能在该句的主要主语和主要动词前使用连词。
7.句子不完整Many students have a hard time passing all the tests to getsintoscollege. For example, my friend in high school.句子没有主要主语或主要动词，因为其实它应是一个从句。这是一个非常常见的错误，修改的方法是将两个句子连接起来。
8.不要使用get When I got home, I got tired, so I got a book and gotsintosbed. Get太不正式，意思也过于含糊，不适合用在正式的场合。应将get改为一个更加具体的单词，如become, receive, find, achieve,等等。
9.书写难以辨认信息不正确I would like to study in America because all modern technology originated there.传的信息不正确，或者让人听起来觉得可能不正确(如果确实是正确的，应当解释为什么这样，因为读者不认为是正确的)。上述例句中，all的意思是百分之百；我们不能绝对地说每一件新东西都是从美国诞生的。为保险起见，应当使用many或most。非英语单词Computers are very helpful and advantageable.尽管看起来象个单词，其实不是，至少不是个英文单词。使用这个单词的另一种形式。
10.介词多余I would like to discuss about something important that you mentioned about to me ring yesterday. We went to downtown yesterday to buy a watch. When I first came to the US, I did not have a lot of friends in here. In class, my classmate never mentioned about her husband.在表示这种意思时此单词不能与介词连用。这种情况常见于downtown，home，there，here等词。这些词语在英语中是副词而非名词，因而不能在它们前面添加介词。
11.跑题或不相关There are many reasons to buy a car, preferably a nice car.这个意思与文章的主题无关。
12.陈词滥调It is okay for children to fail sometimes.所表达的意思很普通大多数人都已经知道到了，因而就没有必要再说出来。
13.标点问题I love animals. And I like to help them. Because they are helpless. So I want to become a vet.这是一个非常普遍的问题！许多学生在句子中使用了太多的句号，尤其是当他们用手写的时候。
14.重复冗余Personally, I believe what the newspaper prints.一种意思的表述不止一次，或者某个词语不必要。
15.单数/复数Many year ago, dinosaur roamed the Earths.单词需要从单数变为复数，或者由复数变成单数。单数可数名词单数可数名词不能单独使用，应该将其变为复数形式或者加上限定词(a, the, my, his, her, Gary's, no, any, 1, 3, 50, most,等等)。
16.拼写错误主语、动词或宾语有问题I want to buy something for my mother that she will like it. There was a terrible accident happen yesterday.句子的基本结构有问题缺少主语、动词或宾语，或者这些成分重复。
17.语气与文章不符I was kind of mad at the guy who vociferated angry words at me. I have heard many wonderful things about such cosmopolitan cities as Paris, London, Tokyo, and Hong Kong and I would love to visit these cities to check them out.语气与文章其他部分不相符可能是过于正式或者太不正式。
18.代词指代不明If people do not speak the same language, it has a greater chance of miscommunication. I intend to complete my studies in the United States because they have good programs there.代词所指代的指示词(介词所代替的名词)不清楚。
19.过于笼统We should use our resources on Earth because the Earth is getting worse.句子或它所表达的意思过于笼统，不能提供多少信息。
20.动词时态错误Yesterday I will go to the store because tomorrow I needed some food.动词时态不正确检查一下是应该用现在时、过去时、将来时还是完成时等等。
21.选词不恰当I was late getting home because I lost my way.在这种情况下不应该使用该词可选择更好的词语或者所使用的词语与文章的总体语气不符。
22.单词形式不当I want to creation a great web site so that I can becoming wealth.所使用的单词的形式不正确检查一下应该使用该词的名词、形容词或副词形式的哪一种。
23.用词错误Even I don't speak Spanish, I was able to find a bathroom in the department store. I gained a lot of pounds ring vacation.用词错误或在此种情况下该词不是最佳用词。
㈡ 英国论文写作常见问题或者错误有哪些
英语写作常见问题：用字愈难愈好
写作时应该要尽量避免难字，因为难字通常容易拼错，且考试时又无法查字典确认拼法；此外，除非你很清楚知道某个难字的确切意思及用法，否则也容易误用此字，倒不如利用自己熟悉且有把握的单字，这样才能在平稳中求取高分，至少也不会被扣分。举例来说，大家都知道，buy是买，purchase也是买，但是前者很容易拼写，后者则较难，因此除非你能正确拼写purchase，考试时还是选用有把握的buy比较妥当！
英语写作常见问题：句子愈长愈好
和上一个误区类似，很多考生以为，英文句子写得愈长，愈能凸显自己的写作功力，因此常常写了一大段，才在段落的最后打上一个句点。这样可就大错特错！为什么呢？因为英文句子不是中文句子，可以写一长段再打句号。英文句子必须谨守一个句子只有一个主词、一个动词的原则，因此一个句子只要出现了一组主、动词，便要在另一组的主、动词出现前打上句号，将两组主、动词区隔。其实英文句子写得愈长，出错的机会也愈高，因此倒不如利用简短句子，确保每句切入要旨，偶尔再用连接词等方式加长句子的长度。
英语写作常见问题：句子愈复杂愈好
很多考生在写作时，总喜欢把每个句子写得很复杂，不是关系代名词which、that满地跑，就是倒装句型（例如：no sooner did I come home…）充斥，让人看了雾飒飒。虽然写作时不要整篇都用差不多的句型，这样会让文章显得乏味，但这并不是说写作时必须每一句都用复句、合句等，因为若整篇文章的每一句都是关系子句，读起来反而很吃力，且如同第二个迷思，句子愈复杂便愈容易出错，反而弄巧成拙；倒不如在写作时让大部分的句子是简单适切的短句或简单句，偶尔再穿插几句复句、合句。
英语写作常见问题：文章愈长愈好
很多考生以为，写作时最好将整张稿纸填满，这样才显得内容丰富，而且也较容易博取阅卷老师的同情分数。事实上，大部分的阅卷老师虽然都心地善良，但是对于满纸荒唐言的作文还是不可能违背良心，给出高分的。如果细看各类作文考试的评分标准，组织结构与内容通常占了总分的一半或以上，由此可知，文章不是落落长就好，而是必须有结构、言之有物。如果为了凑字数，或者在没有结构的情况下东一句、西一句，想到哪写到哪，便容易让阅卷老师看穿自己对英文作文认识的浅薄，得到反效果！
英语写作常见问题：标点符号不重要
标点符号虽然可以有小错误，但如果过多的标点符号问题，就会引起反感了。要记得英文的标点符号中没有顿号，且中文的引号及双引号在英文中也要注意，英文标点在细节上有所不同，学会区别，也应当重视起标点符号，当养成习惯了也不会觉得标点符号有问题。
英语写作常见问题：将中文的想法翻译成英文
中、英文差异很大，中文句子与英文句子当然也是两种截然不同的东西。要了解这点，我们必须从东西方的思维着手。简单地说，中国人重视个人的感受及心领神会，反映在中文句子上，便重意合，动词多，连接词少，不怕重复，一句话可以无限延伸，直到语气的完结点。西方则重形式论证，强调理性分析，反映在英文上便重形合，所以由抽象名词当主词的机会多，被动式也用的多，连接词、介词用得更多。也因此，英文文法要求严格、结构紧凑而严密，句子的主体十分突出。

㈤ 中学生英语作文常见错误及对策，的背景怎么写
如果给了中文意思就逐句翻译,给了中文或英文关键词就自己编,有给表格或信息的就按这些写.题目中给出的一切信息都要在你的作文中表现出来.
单给一个题目就围绕题目自己联想,有些带问题或要求的一定要在你的作文中能找到题目所问问题的答案或满足题目中的要求.
总之题里所给的所有东西都不要漏掉就行了.
一定要有开头和结尾.这个自己可以多看一些英语短文,就会写开头结尾了.看课本上的课文就可以.特别是结尾一定要有总结句.比如写自己理想职业的作文,开头可以写"Everyone has a dream.Do you want to know my dream?",结尾可以写"So I have to study hard in order to be a engineer in the future.What's your dream?".
关于作文字数的问题,如果单是写了题目中给的信息一般字数肯定不够,这就得要你自己加东西.可以加从句感叹句之类的.形容词也可以多用.大概加一两个从句就行了.
最好在文章里用上一些自己知道的比较难的词组和句型,因为有的老师扣分狠,即使满篇没有语法错误也会因为语言太过平淡而不给你满分.
最后一定要检查语法有没有问题.一般的老师都会在语法错误上扣分.还有最好用一些不同的连词把全文贯穿起来.连词用得不合适或是缺少连词也都会扣分

㈧ 阅卷老师总结：英语作文常见10大问题，你中枪否
有很多同学和家长都向我咨询过提高英语成绩的好方法。前段时间也给大家分享过一些英语单词的记忆，英语语法，那么今天我就着重讲一下英语作文。
英语作文的写作技巧固然重要，但是我们在写作之前必须弄清楚要规避哪些常犯的错误，只有了解了这些常规性的错误，写作时才会避免自己犯错，英语作文得分自然不会低。
在我的教学经验中，大部分同学几乎都会犯这10完全可以避免的错误。
1. 审题不清
无论是语文作文还是英语作文，偏离了主题都是致命伤！只要偏题，不管你语言如何规范、准确，都会被判零分。所以，同学们在写作之前一定要把题看清楚，最好是拿笔把关键词勾画出来，以免遗漏或错误理解导致偏题。
比如作文要求写一项最喜欢的课外活动，有些同学审题不清就容易写成“我最喜欢的活动”偏离了“课外活动”这一主题，这样写出来的作文基本得分不高。
2.拼写错误
单词拼写一直是很多同学的硬伤，单词拼写是由单词记忆得好坏直接决定的。一篇文章里有大量的错误拼写不仅会让阅卷老师觉得英语基本功差，同时也直接影响作文内容的表达，阅卷老师都看不懂这篇作文，得分自然就很低。
因此我建议，同学们在平时的学习中要重视单词背诵，如果在作文中有不确定的单词，那最好是用一个比较简单的同义词来代替。
3.名词单复数的错误
名词的单复数是一个很重要的知识点，但是它其实是很简单的，几乎所有的同学都能掌握，但就是由于粗心大意经常写错。
例如“我父亲和母亲都是教师”这一句话，我经常看到很多同学这样写“my father and my mother is all teacher.”这里的“teacher”是“father”和“mother”的指代，是复数，用单数的“is”就是错误的。正确的应该这样“my father and my mother are both teachers.”
而这种低级错误是完全可以避免的，另外，在改错题和选择题中也会出现这样的情况，大家要注意这种送分题。
4.缺少动词
因为语言习惯的不同，一些同学在作文中常缺少动词，因为汉语的一句话中，可以不表达动词，而在英语中则不行。
例如“我很高兴我能来到中国”，这个句子没有动词作谓语，而用形容词，但英语形容词不能作谓语。很多同学这样错误的翻译“I happy I can come to china.”里面就缺少主语“I”后面应该接的动词做谓语，正确的应该是“I am happy I can come to china.”
5.缺少介词、冠词等
还有一些同学因为没有熟练掌握介词或者冠词的用法，不了解中英文语言习惯的不同，也会出现明显的错误，造成丢分现象。
例如：“因为大雨我们不能举行运动会”错误的写法为“because heavy rain we can't hold the sports meeting.”正确的应该这样写“because of the heavy rain we can't hold the sports meeting.”
6.代词的错用
在英语有很多代词的形式，包括主格、宾格、物主代词、反身代词等。而汉语中没有主格和宾格、形容词性物主代词和名次性物主代词之分。
此外汉语中很多时候不用物主代词，而英语中物主代词是不可省略的，代词的误用是考生最容易发生的错误。
例如：错误的写法“I mother and i went to the shop to buy a present for i father.”这里的“I”就用错了，汉语中时常说“我母亲……“，但是在英语中应该是”我的母亲“，所以正确的应该这样写：“my mother and i went to the shop to buy a present for my father.”
7.句子不完整
有的同学没有弄清楚英语中的句子结构，因此长出现只写半句的现象。
例如：错误的“many students have a hard time passing all the tests to get into college. for example, my friend in high school.”这段文章的第二句话没有动词，他不能独立构成一个句子。这是一个非常常见的错误，修改的方法是将两个句子连接起来，把中间的句号改为逗号即可，正确的“many students have a hard time passing all the tests to get into college, for example, my friend in high school.”
8.前后不一致
这也是很多同学常犯的错误：数量的不一致、时态不一致及代词不一致、主谓不一致等。
例如：1. “人一旦有了知识，他就能想干什么就干什么。”错误的写法“when one have knowledge, he can do what he want to do.”这里one是单数第三人称，因而本句的have应改为has ;同理，want应改为wants。这是典型的主谓不一致。因此，应该这样改“when one has knowledge , he can do what he wants (to do)."
9.时态、人称和数的搭配错误
汉语动词无时态、人称和数的变化，而对英语来说，这些都至关重要，这也是英语语法中的难点。
例如“当我到达车站时火车就已经开走了”，错误的写法“when I get to the station the train leave.”这句就是典型的时态错误，错误的示例中用的一般现在时，但是第一人称“I”在说出这句话时，无论是“到达车站”这件事还是“火车开走了”这件事都已经发生了，那么当“我到达车站时”发生在说出这句话的现在之前，所以应该用一般过去时“get”应该改为过去式“got”；“火车已经开走了”是在“我到达车站”之前就开走了，所以是过去的过去，因此，要用had left（left是leave的过去式）。正确的应该是“when i got to the station the train had left.”
10.其他错误
除了上述的9点语法与拼写的错误之外，还有单词的大小写、标点符号的错误等，以及形容词和副词的混淆、连词的误用等等。
其实这些错误都是基础知识没有掌握好或者粗心大意造成的，同学们平时应该多加练习，“熟能生巧”，只要做得多了，自然错误就少了。
㈨ 英语写作要注意的几种情况：常见的10个句子错误
Incomplete Sentence - Sentence Fragment
句子不完整——残缺句
One common mistake many students make is the use of incomplete sentences. Each sentence in English must contain at least a subject and a verb, and should be an independent clause. Examples of incomplete sentences without a subject or a verb might include an instruction or a prepositional phrase.
许多学生都会犯一个常见的错误，就是写出来的句子不完整。英语中，每个句子都必须至少有一个主语，一个动词，并单独成句。没有主语或动词的残缺句子可能就只有表示指令的句子或者介词短语了。
For example:
例如：
Through the door.
穿过大门。
In the other room.
在另一个房间。
Over there.
在那里。
These are phrases we may use in spoken English, but that should not be used in written English as they are incomplete.
在英语口语中，你可能会用到这些短语，但是因为它们毕竟不是完整的英语句子，所以在书面语言中，我们一般不会使用。
Sentence fragments caused by dependent clauses used without an independent clause are more common. Remember that subordinating conjunctions introce dependent clauses. In other words, if you use a subordinating clause beginning with a word such as 'because, though, if, etc.' there must be an independent clause to complete the thought. This mistake is often made on tests asking a question with 'Why'.
由于缺乏独立分句的从属子句导致的句子残缺很常见。记住，从属连词引出了从属子句。也就是说，如果你用一些词语来引出从句，例如because，though，if等等，就必须要有一个独立分句来使句子完整。我们在考试中，使用why来提出问题时，经常会犯这样的错误。
For example, the sentences:
例如，下面这个句子：
Because Tom is the boss.
因为汤姆就是老板。
Since he left work early without permission.
自从他不经允许就早退。
We might answer the question: "Why did he lose his job?" However, these are sentence fragments. The correct answer would be:
我们可能会问：“他为什么丢掉工作?”但是，这些句子都是不完整的。正确用法应该是：
He lost his job because Tom is the boss.
因为汤姆就是老板，所以他丢掉了工作。
He lost his job since he left work early without permission.
他因为不经允许就早退而丢掉了工作。
Other examples of incomplete sentences introced by subordinating clauses include:
其他关于从属子句的残缺句还包括下面内容：
Even though he needs help.
虽然他需要帮助
If they study enough.
如果他们好好学习
As they had invested in the company.
因为他们投资了这家公司
Run-on Sentences
句子不连贯
Run-on sentences are sentences that:
不连贯句子指的是：
1) are not connected by appropriate linking language such as conjunctions
缺乏合适的连接词，例如连词。
2) use too many clauses rather than using periods and linking language such as conjunctive adverbs
使用过多的从句，而非句号和连接语，例如连接副词
The first type leaves out a word - usually a conjunction - that is required to connect a dependent and independent clause. For example:
第一种是漏掉了一个词——通常是连接词——用于连接非独立子句和独立子句。
The students did well on the test they didn't study very much.
学生们考得很好他们没有下多少功夫。
Anna needs a new car she spent the weekend visiting car dealerships.
安娜想买辆新车她整个周末都在约见代理商。
The first sentence should use either a conjunction 'but', or 'yet' or a subordinating conjunction 'although, even though, or though' to connect the sentence. In the second sentence, the conjunction 'so' or the subordinating conjunction 'since, as, or because' would connect the two clauses.
第一句话要么应该加上一个连词but，要么加上yet，或者一个从属连词although, even though或though来连接前后两句。
The students did well, yet they didn't study very much.
学生们考得很好，但他们并没有下多少功夫。
Anna spent the weekend visiting car dealerships since she needs a new car.
因为想买辆新车，安娜整个周末都在约见代理商。
Another common run on sentence occurs when using too many clauses. This often occurs using the word 'and'.
另一种句子不连贯发生在使用太多从句的时候。常常是由于and一词导致。
We went to the store and bought some fruit, and we went to the mall to get some clothes, and we had lunch at McDonald's, and we visited some friends.
我们去商店买了一些水果，去购物商城买了一些衣服，在麦当劳吃的午饭，又见了一些朋友。
The continuous chain of clauses using 'and' should be avoided. In general, do not write sentences that contain more than three clauses to ensure that your sentences do not become run-on sentences.
我们应该避免使用and来连接一大串的从句。一般来说，从句不要超过三个，以确保句子的连贯性。
Duplicate Subjects
两个主语
Sometimes students use a pronoun as a plicate subject.
有时候，学生们会将代词作为第二个主语。
Remember that each clause takes only one sentence. If you have mentioned the subject of a sentence by name, there is no need to repeat with a pronoun.
记住，每个从句只需要一句话。如果之前你已经提到主语的名字，就不需要再用代词重复了。
Example 1:
例一：
Tom lives in Los Angeles.
汤姆住在洛杉矶。
NOT
而不是
Tom, he lives in Lost Angeles.
汤姆，他住在旧金山。
Example 2:
例二：
The students come from Vietnam.
学生们来自越南。
NOT
而不是
The students they come from Vietnam.
学生们他们来自越南。
Incorrect Tense
时态错误
Tense usage is a common mistake in student writing. Make sure that the tense used corresponds to the situation. In other words, if you are speaking about something that happened in the past do not use include a tense that refers to the present. For example:
时态错误在学生写作中很常见。你要确保时态与事情发生的情况一致。也就是说，如果你要表达的是发生在过去的事，就不要使用现在时态。例如：
They fly to visit their parents in Toronto last week.
上周他们坐飞机去看望父母。
Alex bought a new car and drives it to her home in Los Angeles.
亚历克斯买了一辆新车，并把它开进了洛杉矶的家。
Incorrect Verb Form
动词形式错误
Another common mistake is the use of an incorrect verb form when combining with another verb. Certain verbs in English take the infinitive and others take the gerund (ing form).
另一个常见的错误就是在与其他动词连用时，动词形式的错误。英语中的动词既有不定式形式，又有动名词形式。
It's important to learn these verb combinations. Also, when using the verb as a noun, use the gerund form of the verb.
学习这些动词的连用很重要。当动词作为名词使用时，就要使用动名词形式。
He hopes finding a new job. / Correct -> He hopes to find a new job.
他想找一个新工作。
Peter avoided to invest in the project. / Correct -> Peter avoided investing in the project.
皮特没有在这个项目上投资。
Parallel Verb Form
动词复数形式
A related issue is the use of parallel verb forms when using a list of verbs. If you are writing in the present continuous tense, use the 'ing' form in your list. If you are using the present perfect, use the past participle, etc.
在使用多个动词时，有一个问题就是动词复数形式的使用。如果你是在用现在进行时进行写作，就应该使用动词ing形式。如果你使用的是现在完成时，就应该使用过去分词形式。
She enjoys watching TV, play tennis, and cook. / Correct -> She enjoys watching TV, playing tennis, and cooking.
她喜欢看电视，打网球和烹饪。
I've lived in Italy, working in Germany and study in New York. / Correct -> I've lived in Italy, worked in Germany, and studied in New York.
我住在意大利，在德国工作，在纽约读书。
Use of Time Clauses
时间从句的使用
Time clauses are introced by the time words 'when', 'before', 'after' and so on. When speaking about the present or future use the present simple tense in time clauses. If using a past tense, we usually use the past simple in a time clause.
时间从句由时间词语引导，例如when，before，after等等。当我们表达现在或将来的事时，可以使用一般现在时的时间从句。如果使用过去时态，通常会使用过去时的时间从句。
We'll visit you when we will come next week. / Correct -> We'll visit you when we come next week.
下周我们会来看你。
She cooked dinner after he was arriving. / Correct -> She cooked dinner after he arrived.
他到了之后，她才开始煮饭。
Subject - Verb Agreement
主谓一致
Another common mistake is to use incorrect subject - verb agreement. The most common of these mistakes is the missing 's' in the present simple tense. However, there are other types of mistakes. Always look for these mistakes in the helping verb.
另一个常见的错误就是主谓不一致。最常见的就是一般现在时中漏掉了-s。但是，还有其他类型的错误。这些错误常发生在助动词的使用上。
Tom play guitar in a band. / Correct -> Tom plays guitar in a band.
汤姆在乐队里是弹吉他的。
They was sleeping when she telephoned. / Correct -> They were sleeping when she telephoned.
他打电话过来时，他们都睡着了。
Pronoun Agreement
代词一致
Pronoun agreement mistakes take place when using a pronoun to replace a proper noun. Often this mistake is a mistake of use of a singular form rather than a plural or vice versa. However, pronoun agreement mistakes can occur in object or possessive pronouns, as well as in subject pronouns.
代词不一致发生在用代词来替代专有名词的情况下。通常是使用了单复数形式的错误使用。但是，代词不一致也会发生在宾语或物主代词，和主格代名词上。
Tom works at a company in Hamburg. He loves his job. / Correct -> Tom works at a company in Hamburg. He loves his job.
汤姆在汉堡一家公司工作。他热爱这份工作。
Andrea and Peter studied Russian at school. He thought they were very difficult.Correct -> Andrea and Peter studied Russian at school. They thought it was very difficult.
(正确)安德里亚和皮特在学校里学习了俄语。他们觉得俄语很难。
Missing Commas After Linking Language
连接语言后漏掉了逗号
When using an introctory phrase as linking language such as a conjunctive adverb or sequencing word, use a comma after the phrase to continue the sentence.
当我们使用介绍性短语，例如连接副词或表示顺序的词语，通常会在短语后面打上逗号来连接下文。
