主谓不一致，人称与动词不符。例如：
My sister go to the cinema at least once a week. (误)
My sister goes to the cinema at least once a week. (正)
上面例句中，主语是My sister ，为第三人称，所以谓语动词应该用第三人称单数形式goes才正确，这种主谓不一致的错误在写作中是很常见的问题，稍一疏忽就会犯，考生需要更加细心才行。
句子成分残缺不全，语句不通。例如：
We should read books may be useful to us. (误)
We should read books which may be useful to us. (正)
这是一个定语从句的例句，其中which在从句中做的是主语，所以不能省略，一旦省略就会造成句子成分残缺，考试中大家在写完一句话时要记得读一遍看看通不通顺。
句子成分多余，累赘复杂。例如：
This test is end, but there is another test is waiting for you. (误)
One test ends, but another is waiting for you. (正)
这一句的错误有点中式英语(课程)的味道，逐字逐句对应翻译，there is 放在这里，累赘而又繁琐。
希望能帮助到你，望采纳！
B. Essay写作常犯的错误有哪些
一、论点不明确
论文的开头写了不少字，但不知他到底提出了一个什么问题？例如，“我之所以选择这个题目，主要是因为我已多次从事这方面的工作实践，积累了很多经验，也有很多体会和感受，下面就从三个方面将我的这个论题论述一下（大标题中也没有提出论点）。”看了这些内容，读者很容易认为下面要写经验和心得体会，至于要写什么，读者依然不能明白。题好一半文，有的学生居然想起一个好听的题目然后在文章中论述清楚，这是不行的。一定要在题目当中就讲得简洁、清楚、准确，一般情况下，论文题目就是整篇论文的中心论点。
二、材料和观点不统一
材料就是要用来说明或论证意图及观点的，论文不能只有空洞的意图或观点而没有材料，也不能只有材料而没有意图或观点，因此，材料和观点要统一。不仅如此，论文写作还要求掌握的材料、情况要真实、系统，即材料、数据的内容要符合客观实际，能够反映事物的本质和主流，能够证明自己观点的正确。学生的材料和观点不统一表现在：
1.材料与观点不相干。有的留学生理论水平不够，平常的学习和生活都沉浸在外出旅游里了，等到论文最后上交的时刻就去电子图书馆、资料室等去查找，凑够字数了才发现，与自己要证明的观点其实是不太有关系的。
2.材料说明观点的力度不够。有的材料不能充分说明自己的观点，也就是论据不充分。要证明观点，材料越充分越典型越有说服力越好，要尽量多找，然后进行分类和筛选。
3.材料与观点相矛盾。有的留学生的论文，会出现只有意图、没有材料，或意图与材料相矛盾的情况。
C. 高考英语写作最易犯的100个错误（上），你犯了多少
一. 名词
写作中，学生们常把握不好名词的数、所有格以及一些集合名词的用法。
1. He gave me a very good advice yesterday.
句中的a要去掉，因为advice是不可数名词。一些汉语概念为可数的词在英语中却是不可数的，表示数量时在其前加a piece of，类似的词有：news, bread, work, paper, chalk, furniture, information等等。
2. That girl loves reading book.
可数名词单数不能孤零零地放在句子里，或前面加冠词，或将其变为复数。此处最好变为books.
3. He went into a book’s shop and bought a dictionary.
一般表示有生命的东西的名词的所有格用’s，如my mother’s car, 而此处适宜用名词修饰名词，改为a book shop.
4. My family is watching TV.
一些集合名词如看成一个整体，则用单数的谓语动词，如My family is a happy one; 如强调集合中每个个体的个人行为，则用复数的谓语动词。此处看电视是个体行为，应把is改为are。类似的词有：team, class, audience等。
5. I bought some potatos and tomatos at the supermarket.
中学阶段以“o”结尾的名词中有四个词变复数时要加es，它们是tomato, potato, Negro, hero; 其余的都加s变为复数。
6．This has nothing to do with their believes.（这和他们的信仰没关系。）
以f, fe 结尾的词变为复数时一般去f, fe 加ves，如knife—knives, thief—thieves; 而roof 和belief直接加s变为复数。所以应把believes改为beliefs.
二. 冠词
7. The boss wants to hire an useful person.
用a还是an，取决于后面单词的第一个音标，如为元音用an，为辅音用a。useful的第一个音是辅音所以应把an改为a。类似的，我们说a European country.
8．Plane is a machine that can fly.
Plane为可数名词单数，不能单独放在句中，应在其前加冠词或把它变为复数，而本句后有a machine, 因此只能在其前面加a，变为A plane。
9．He played a piano at the party yesterday.
把a 改为the ，因为乐器前用定冠词。
10．The machine was invented in 1920s.
在in后加the，因为表示年代用in加the再加几十的复数，如在八十年代in the 80s。
11．Xiao Hong went to school by the bus every day.
去掉the，因为表示交通方式用by直接加交通工具。
希望能帮助到你，望采纳！
D. 英文论文写作中常犯的错误有哪些求列举一些，看看我有没有犯
一、修饰语错位（Misplaced Modifiers）
英语与汉语不同，同一个修饰语置于句子不同的位置，专句子的含义可能引起属变化。对于这一点中国学生往往没有引起足够的重视，因而造成了不必要的误解。
二、不一致（Disagreements）
所谓不一致不光指主谓不一致，它还包括了数的不一致,时态不一致及代词不一致等。
三、悬垂修饰语（Dangling Modifiers）
所谓悬垂修饰语是指句首的短语与后面句子的逻辑关系混乱不清。
四、句子不完整（Sentence Fragments）
在口语中，交际双方可借助手势语气上下文等，不完整的句子完全可以被理解。可是书面语就不同了，句子结构不完整会令意思表达不清，这种情况常常发生在主句写完以后，笔者又想加些补充说明时发生。
五、指代不清（Ambiguous Reference of Pronouns）
指代不清主要讲的是代词与被指代的人或物关系不清，或者先后所用的代词不一致。
E. 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。

希望能帮助到你，望采纳！
G. 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。
H. 英语写作中最易犯的10类错误，你有几个
1. 审题不清
如某一年的中考作文要求写一项最喜欢的课外活动，有些考生将作文的主题定位为“我最喜欢的活动”，偏离了“一项、课外活动”这一主题。依据作文的评分原则，若文章内容不切题，则不管语言如何规范、用词如何准确，都会被判为零分。
2. 拼写错误
拼写是考生应该具备的最起码的基本功，但在考生的作文中却经常能发现很多拼写错误。有拼写错误的作文肯定会被酌情扣分，而且有大量拼写错误存在的作文不仅体现出语言基本功差，同时也直接影响内容的表达，通常会降低作文的档次。
3. 名词单复数问题
误：My father and my mother is all teacher.
正：My father and my mother are both teachers.
4. 缺少动词
在汉语中没有动词的句子是允许的，但英语中每个完整的句子都必须有动词来构成，如：“我累了。”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，一定要写成：I'm tired.
误：I happy I can come to Beijing Zoo.
正：I am happy I can come to Beijing Zoo.
误：The apples cheap. I'll take some.
正：The apples are cheap. I'll take some.
5. 缺少介词、冠词等
还有一些考生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。
误：Because heavy rain we can't hold the sports meeting.
正：Because of the heavy rain we can't hold the sports meeting.
6. 代词的误用
英语中代词的形式很多，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词性物主代词之分。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之一。
误：I mother and I went to the shop to buy a present for I father.
正：My mother and I went to the shop to buy a present for my father.
7. 句子不完整
有的考生因为对句子结构认识模糊，所以出现只写半句的现象，这也是造成失分的原因之一。
误：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，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。)
正：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
所谓不一致，包括数的不一致、时态不一致及代词不一致、主谓不一致等。
误：When one have knowledge, he can do what he want to do.
（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。本句是典型的主谓不一致。
正：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。
误：When I get to the station the train leave.
正：When I got to the station the train had left.
10. 综合性错误
综合性错误是指单词的大小写和标点符号的错误等，以及形容词和副词的混淆、连词的误用等等。这些都是靠考生平时知识的积累，所以考生应该从平时练习出发，每天坚持写英语日记，多读适合自己英语水平的原版著作，提高自己的英语素养。
