写作是对同学们英语综合能力的考查，是最能体现大家英语水平的一种检测方式。学生在写作的过程当中经常会暴露一些弱点、犯一些错误。今天，我们对大家英语作文中的常见错误进行简要归纳，并举以实例，大家在今后的英语写作中要尽量避免这些错误的发生。

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.Hegavemeaverygoodadviceyesterday.

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，表示数量时在要其前加apieceof，类似的词有：news,bread,work,paper,chalk,furniture,information等等。

2.Thatgirllovesreadingbook.

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.Hewentintoabooksshopandboughtadictionary.

一般表示有生命的东西的名词的所有格用’s，如mymother’scar,而此处适宜用名词修饰名词，改为abookshop.

4.MyfamilyiswatchingTV.

一些集合名词如看成一个整体，则用单数的谓语动词，如Myfamilyisahappyone.如果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.Iboughtsomepotatosandtomatosatthesupermarket.

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.Thishasnothingtodowiththeirbelieves.（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.Thebosswantstohireanusefulperson.

用a还是an，取决于后面单词音标中的第一个音，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aEuropeancountry.

8.Planeisamachinethatcanfly.

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amachine,因此只能在其前面加a，变为Aplane。

9.Heplayedapianoatthepartyyesterday.

把a改为the，因为乐器前用定冠词。

10.Themachinewasinventedin1920s.

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inthe80s。

11.XiaoHongwenttoschoolbythebuseveryday.

去掉the，因为表示交通方式用by直接加交通工具。

三.代词

使用代词时请注意其单、复数，主、宾格以及形容词性物主代词和名词性物主代词的用法。

12.Heisoneofthosespeakerswhomakehisideasperfectlyclear.

定语从句的先行词是thosespeakers，为复数，因此从句中的指示代词应为复数，应把his改为their。

13.Whomdoyouthinkhasleftthelightson?

放在疑问句特殊疑问词后的doyouthink/believe/guess/imagine/suppose等都不参与句子成分。本句中去掉doyouthink后缺的是主语，应把Whom改为Who。

14.ThebosspretendednottoseeJohnandI.

John和I在句中都做的宾语，应把I改为me。

15.Thesebooksaremine；thoseinthebagareher.

her是形容词性物主代词，后面应该加名词books，或把her改为hers。

四.数词

16.Therearefourteenhundredsstudentsinourschool.

hundred/thousand/million/score/dozen等词前有具体数字时后不加s，前面没有具体数字时在其后加s和of，表示大约几百几千的概念。如two

hundredstudents（两百个学生），hundredsofstudents（成百上千个学生）。例句中应把hundreds改为hundred。

17.Theirschoolistwiceaslargerasourschool.

表倍数关系的as...as中间只能用形容词或副词的原级。因此应把larger改为large.

18.Today’shomeworkisafive-hundred-wordscomposition.

几个单词由连字符连接而组成的复合形容词中的名词只能用单数，所以把five-hundred-words改为five-hundred-word.

19.TwothirdofthestudentsinourschoolarefromAmerica.

英语表达中分数的分子用基数词，分母用序数词，分子大于一时分母后要加s，所以就把third改为thirds.

五.形容词和副词

形容词和副词容易被误用，形容词和副词的比较级和最高级也是应注意的重点。

20.Thepatientappearednervouslywhenhetalkedtothedoctor.

appear在此是个系动词，其后应接形容词作表语。所以应把nervously改为nervous.

21.Theartistworkedhardlytofinishhisdrawingsontime.

此句需要一个副词来修饰，hardly是副词，但意为“几乎不”，hard也可以是副词，表努力，因此把hardly改为hard.

22.Thisshirtismorecheaperthanthatone.

more只构成比较级，而不能修饰比较级。因此把more去掉。

23.Heisthemostsuccessfulofthetwobusinessmen.

两者相比较时，比较级前用定冠词，三者或三者以上才用most，因此把most改为more.

24.Heworkslessharderthanheusedto.

表不如?...时用less加上形容词和副词的原级，因此把harder改为hard.

25.Thebookisfairlymoreinterestingthanthatone.

fairly只能修饰形容词和副词的原级，可以修饰比较级的副词或短语有：much,even,still,far,alot,alittle,abit,any,no,byfar,rather等，因此把fairly改为rather.

26.Thisisasaninterestingastoryastheoneinthemagazine.

as?as中间的词序是as加上形容词加上a(n)加上名词再加上as，因此应改为asinterestingastoryastheone.

27.Theweatherhereisnicerthan.

同样的事物才能相比较，weather和不具有可比性，因此应改为Theweatherhereisnicerthanthatof.

29.Iwouldrathertakeatrainthanwentbybus.

这个词组为wouldratherdo?thando?，因此把went改为go.

30.Isthereinterestinganythingatthemeeting?

修饰anything,something,everything,nothing的形容词都要放在它们的后面。

31.Ineverhaveseensuchapersonbefore.

像never之类的副词在句中应放在be动词、助动词之后，实意动词之前。因为应改为Ihaveneverseensuchapersonbefore.

32.Thebookisworthtoberead.

beworthdoing意为值得被做。因此改为Thebookisworthreading.

33.Itissurethathewillsucceed.

sure的主语只能为人，而certain的主语可为人和物。因此把sure改为certain.

34.Heisregardedasoneofthebestalivewritersatpresent.

alive为表语形容词，偶尔也做后置定语。因此把alive改为living，或把alive放在writers后面。

35.Idon’tknowthathehasfinishedtheworkyet.

yet用于否定和疑问句，already用于肯定句。把yet改为already.

36.Hesaidnearlynothingatthemeeting.

nearly不与否定词用在同一个句子中，而almost可以。因此把nearly改为almost。

六.介词

37.Heusuallygoestoschoolbyhisfather’scar.

by加上名词表示一种交通方式，中间什么都不加，如bycar,bybus,byplane等；如果名词前有其他的词修饰，则应用除by以外的其他介词，此处把by改为in.

38.Pleasewaitmeattheschoolgate.

wait为不及物动词，需加介词for后才能再跟名词或代词做宾语。

39.HehasbeenmarriedwithBettyformorethantwentyyears.

marry不跟with连用，应把with改为to。

40.Ifinishedtheworkontimeunderthehelpofhim.

My father is 37 years old, he has a pair of bright and piercing eyes, eyes there are some years left traces. Dads hair is very short, he said it can be convenient to wash your hair. In my mind, he always wore the dirty clothes, two hands very rough, a look to know his work is very hard.

In my hometown, the air is polluted seriously. However, in recent years,

the pollution gets from bad to worse, because of the increasing number of

private cars. Especially during the rush hours, too many private vehicles move

slowly on narrow roads, emitting a large amount of waste gas. Moreover, the

poisonous gas sent by the nearby factories is also one of the main causes of

pollution. Therefore, it’s demanded that immediate and effective measures must

be taken to restrict private cars and public transportation must be developed to

the largest extent. Besides, we should use renewable and clean energy

recourses.

I think reading as the most rewarding entertainment activities in my spare time.

Not only does reading provide me with a wide range of knowledge, it also broaden my mind towards the world. Different sorts of books contain various thoughts of life, work, relationships and cultures. When reading a novel, I can experience joys and tears of the characters through one story after another. When it comes to a biography ,I can even speak to the great person as if he stood towards me. Don’t always regard reading as tools to prepare for exams or show off how knowledgeable the person is.

A true reader is the person who shows knowledge naturally while communicate with others. Reading indeed has an important impact on people’s behavior, which is the reason why I will never give it up.

When the young people start their career, they will do everything to get

the chance to help their career to make breakthrough, such as follow the

limitation of their bodies. The coming wealth is based on the loss of health.

The media reported the news about how the young people died of drinking a lot of

alcohol. Their ambition made them to undertake the limitation. As a result, they

died at the young age. There is no doubt that health overweighs wealth. If a

rich people didnt have a sound body, how he can enjoy life. A man who has been

badly ill will take special attention to the health. No matter how much money he

is paid, he will turn down the invitation that hurts his body.

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

How I Spent My Summer Vacation

The summer vacation had come round again. I was happy that I could forget about school at least for a while. Lest I fool around all through this summer vacation, I made a plan as to how to spend it. First, I thought I should go over all those things my teachers taught in the previous term so that I could have a better understanding of them. Then I thought I should take up some forms of exercise, such as walking, running and rowing, to keep me physically strong. It stood to reason that with such a good plan I should make the best of my vacation time. I did, because I lived up to what I had planned.

summer can be very hot in southern tai wan where the temperature usually goes up to 32"c or more. because of the heat it is a trying experience to go to school or do anything else in a place that is not air-conditioned. also because of this i stay at home most of the time during the summer vacation and occasionally go to the beach to plunge myself into the cool water as a way to keep my body less sticky. actually i like swimming think nothing is more refreshing than a swim. in the summer vacation that has ended i went swimming many times with my classmates we all had a good time. this summer vacation, however, was not spent entirely in seeking fun. as a second-year senior student i had to prepare myself for the college entrance examinations that were a year away. in other words, i must find time to study, too. so i divided my time between work play during the summer vacation derived benefit from this arrangement.

i spent this summer vacation in quite a different way. i used to run about every day in previous summer vacations,this summer vacation i simply could not afford to do so. i would soon be in the last year of my high-school education would after graduation be up against the college entrance examinations. though those examinations were still a year away, i had to start early to make myself well prepared by reviewing all those things i had learned at school this summer vacation was the ideal time for me to do this. at first i was rather dismayed at the thought of this,later i thought it was better this way because by working hard this summer i could count on endless happy summers to come. with this in mind i then set to work like anything and occasionally went out for a change or did some physical. i was not at all bored by this kind of life, for i was sustained by a hope.

the summer vacation had come round again. i was happy that i could forget about school at least for a while. lest i fool around all through this summer vacation, i made a plan as to how to spend it. first, i thought i should go over all those things my teachers taught in the previous term so that i could have a better understanding of them. then i thought i should take up some forms of exercise, such as walking, running rowing, to keep me physically strong. it stood to reason that with such a good plan i should make the best of my vacation time. i did, because i lived up to what i had planned.

[暑假有意义的事高中英语作文200词

I am xxxxx. I was born in Changsha. I graduate from senior high school and major in English. I started learning English since I was 12 years old. My parents have a lot of American friends. That’s why I have no problem communicating with Americans or others by speaking English.

In my spare time, I like to do anything relating to English such as listening to English songs, watching English movies or TV programs, or even attending the activities held by some English clubs or institutes. I used to go abroad for a short- term English study. During that time, I learned a lot of daily life English and saw a lot of different things.

I think language is very interesting. I could express one substance by using different sounds. So I wish I could study and read more English literatures and enlarge my knowledge.
