[四级考试英语作文常用句型

假若你是《21th century》报纸的编辑，有一学生向你写了如下的一封信，请你根据来

信的内容写一封回信，帮他出出主意。字数约为100左右。

Dear Editor,

My physics teacher is very strict with us. I often feel nervous in his classes because we are punished by being made to stand for a few minutes if we cant answer his questions. Its embarrassing (尴尬) to be made to stand in class, so I hate physics classes. However, I really want to do well in physics. What should I do?

Yours sincerely

Zhang Ying

Dear Zhang Ying,

I am sorry you are having difficulty with your physics classes. Teachers have many different ways of encouraging students to put in more effort — it seems as though your physics teacher thinks fear is the best way! He does it because he thinks it will produce results. If you feel that it is stopping you from doing your best then you should tell him. You say you want to do well in physics and if your teacher knows this, he will be pleased. It is only when students are not trying as hard as they can that a teacher is forced to take action. If he is aware of your worries, perhaps he will suggest other ways of helping you improve your work.

Editor

张颖

亲爱的张颖，

我很抱歉你在物理课上遇到了困难。老师们有许多不同的方式鼓励学生投入更多的精力，这似乎是你的物理老师认为恐惧是最好的方式！他这样做是因为他认为这会产生结果。如果你觉得这是阻止你做你最好的，那么你应该告诉他。你说你想在物理方面做得很好，如果你的老师知道这一点，他会很高兴的。只有当学生没有尽可能地努力，他们可以教师被迫采取行动。如果他知道你的担心，也许他会建议其他的方法来帮助你改善工作。

Everyone has his own personality, my room is the most can reflect my personality. As long as you come to my room, you will find that my room has a clear theme of cartoon.

每个人都有自己的个性，我的房间最能体现我的个性。只要你来到我的房间，就会发现，我的房间有一个明确的主题----卡通。我的墙面是浅蓝色的，我喜欢蓝色，蓝色是天的颜色，蓝色是那么纯洁、无暇。墙上贴着7、8张我喜欢的海报。

瞧，印入你眼帘的是一张可爱的书桌，它虽然没有闪耀的宝石漂亮，但我却十分珍惜它，因为它是我学习的一部份，每一个宁静的夜晚或深夜，我都会认真，专心致致，坐在那里写作业，每一个阳光明媚的早晨，我都大声朗读，小鸟也随伴我歌唱。另外书桌上还摆放着，一些小巧精致的艺术品或水晶陶瓷之类的小饰物等等。如七彩水晶的天鹅，用淡紫色玻璃制成的三朵花和挂在墙壁的一个用八种颜色的卡通表，还别上一枝国色天香的牡丹，绿油油的叶子和一两只五彩缤纷的蝴蝶，美极了。当然还有陶瓷的，不过是放在紫檀木的书架上面的，列有，一套全穿日本服的娃娃和一套印度的的娃娃，还有在书架里有米老鼠，唐老鸭和全套的迪士尼的陶瓷，这通通都是我的珍藏品。

书桌的旁边是我最喜欢的床，床上是印有小熊维尼图案的四件套，这张床在我的屋里显得格外温馨、可爱。累的时候，我就会躺在上面，是那么舒服，软绵绵的。在床的右方还有一个使你感到温暖如春的空调。在炎热的冬天，开启空调，会感到好冰凉，好爽;在寒冷的冬天，开启空调，会感到好暖，好舒服。空调的功能真不错!

你看那扇明亮的窗户，它被一个落地窗帘罩住了，窗帘上面有一片片五颜六色的叶子，还有两只展翅欲飞的蝴蝶。在炎热的夏天，我看着窗帘就会想到秋天，那一片片的叶子好像在随着秋风在空中飞舞，而我也似乎感觉到一阵阵秋风的凉意，心情便不再浮躁，而是变得十分宁静。

在我房间的顶上有一盏太阳图案的大吊灯，它总能让我进入甜甜的梦乡。

这就是我的房间，可爱、漂亮、我爱我的房间!

1、失败是常有的事

2、人们对失败有各种不同的态度。

3、我对失败的态度。

Is Failure a Bad Thing?

Failure is a common thing in our daily life. For example, sometimes we fail to pass the examinations. On other occasions, we are defeated in sport games. And there are times when we fail to do more satisfactory work. So it is safe to say that every one of us must have encountered failure of one kind or another.

However, different people have different attitudes towards failure. Some people lose heart when they come across failures. They seem to think that it is the end of the world. Others, on the contrary, don’t take failure seriously. They seem to think that failure is first step to success.

In my opinion, what really counts is not failure itself, but our attitude towards it. If we are afraid of failure and yield to it easily, we are bound to have one failure after another. But as long as we have confidence in ourselves and learn something from failure, we’ll certainly go from victory to victory. So I’m never afraid of failure, or I firmly believe that “failure is the mother of success.”

Good morning , ladies and gentlemen ,

Some of us are having problems with our parents , as they often look into

our school bags or read our diaries . I fully understand why we are not

comfortable about it , but there’s no need to feel too sad. Our parents are

checking our bags or diaries to make sure we are not getting into any trouble .

They have probably heard some horrible stories about other kids and thought we

might do the same . Or perhaps they just want to connect with us but are doing

it all wrong . My suggestion is : Tell them we want them to trust us as much as

we’d like to trust them .If you don’t think you can talk to them , write them a

letter and leave it lying around ---they are bound to read it .

Thank you!

这种空气污染物来自各种自然和人为的来源。自然源包括风吹灰尘，煤烟，野火。人造资源可以包括汽车，工业燃料燃烧和制造业务。造成雾霾的主要原因之一是制造业经营。许多工厂过度测量产生的烟雾超过标准，烟雾严重影响空气成为空气污染。

构成雾霾的成分可能对人们的健康产生负面影响，尤其是儿童和老年人。也不排除那些有某些疾病，如哮喘，过敏，肺炎和肺部疾病。在户外工作的工人在健康方面有很高的风险。

帮助消除雾霾的有效方法之一是在制造过程中进行一些化学变化，从而减少制造过程中产生的有害排放物。

书面表达一直在历年高考中占有很重要的地位，而且相对于其他题型，书面表达最容易在短期内有所突破。下面小编为大家整理了英语作文的突破技巧，欢迎大家阅读。

书面表达在评阅时遵循语言第一位(语言高级)，内容第二位(要点齐全)，结构第三位(文章分段)的原则，也就是说阅卷老师最注重的是语言，换句话说是亮点，根据语言使用情况，亮点的多少而定出档次，所以同学们在书面表达中语言上的亮点是得高分的关键。

亮点一共有四种：

一、高级词汇和语法;

二、修辞手法;

三、有效的连词;

四、名人名言或谚语。

首先简单介绍亮点当中至关重要的高级语法，以及修辞手法当中的一些技巧的使用。

肯定不如否定好

修辞的使用在书面表达中算作很大的亮点，在高中阶段很少有学生会注重修辞的应用。双重否定也是种修辞，而且对于考生来说，只要稍加注意，可以在文章中设计双重否定的句子。例如想表达“邮递员天天准时到”，如果写成The postman comes on time every day，就不如变成双重否定，The postman never fails to come on time，就变成了亮点句，起到强调作用。几乎每个人对生活的态度都不同程度受到地震的影响，写成双重否定There was hardly a man or a woman whose attitude

towards life had not affected by the earthquake.应用类似的修辞会在高考中为同学们加分。

陈述不如倒装妙

在书面表达中阅卷老师喜欢看到的高级语法共有五种：倒装，强调，从句，独立主格和分词结构，以及虚拟语气。倒装是一种最简单易行的使句子呈现亮点的方法。在高中阶段只需掌握倒装的四种形式，足以应对书面表达，如何应用倒装，有很多方法和技巧。

否定词开头

如果写出的句子中有否定词， 例如I will never marry you. 不如变成倒装，用否定词开头Never will I marry you. 就算作使用了高级语法。其他的否定词，如not, seldom, hardly等开头后面的句子倒装都是比较好的句子。

地点状语开头

在很多年的高考书面表达中都有表达地点的句子，一个建筑位于什么位置，或什么地方有什么东西，都可以应用倒装。例如在2006年的全国卷中，图书馆位于学校的中央，Our library is in the center of our school.变成倒装就用地点状语开头：In the center of our school lies our library. 其他的例子，想表达河岸上有很多花:On the bank stand some flowers. 天空中繁星点点：In the sky hang little stars. 总之在想表达地点时就把地点状语放在句首后面主谓倒装。

这样做的好处之一是倒装本身就是高级结构，第二是倒装后把真正的主语放到了句子的末尾，后面还可以继续加从句，使整个句子再呈现更多的亮点。例如In the center of our school lies our library，which is between the garden and the teaching building.

Only+介词短语

例如在2007年全国卷中，让外教帮你找个笔友，有一句可以表达成只有通过这种方式我才能提高英语，这句话可以写成Only in this way can I improve my English.其他的例子还有Only by taking exercises can we keep healthy.

形容词+as+主语+be动词

例如Young as I am, I can manage it; Rich as our country is, we have a lot of problems. 2000年书面表达中：Badly injured as he was, he managed to take down the

car’s number. 还有其他的倒装结构，很高兴收到的你的来信：So glad am I to hear from you.在高考中要尽量使用一两个倒装。

主动不如被动巧

在近些年的阅卷中，发现考生在写作中很少使用被动语态，也许是受中文思维的影响，几乎整篇文章都使用主动语态。其实在英文中，被动语态的使用是很重要的。因为英语是一门客观的语言，而汉语是主观的语言，具体体现在英语中经常用被动语态，汉语经常用主动语态;英语中经常用物称或形式主语开头，强调一件事发生在什么人身上，而汉语经常用人称开头强调一个人发生了什么事。所以使用被动语态符合英语的习惯，如果能将整个文章中两个句子变成被动语态，就会呈现句型的变化，使整个文章句型丰富。

例如在2006年的高考中，很多学生在表达我们每次可以借五本书最多借十天时，都是用：We can borrow five books at most, and we can keep them for ten days.这句话如果写成：At most five books can be borrowed at a time and they can be kept for ten days，分数会更高。

分词结构不能少

在前文提到，在书面表达中老师喜欢看到的高级语法共有五种：倒装，强调，从句，独立主格和分词结构，以及虚拟语气。在所有的高级语法中，阅卷老师最喜欢看到的是独立主格和分词结构，其次是剩下的几项。但很多学生不知道如何在文章中使用这个最大的亮点。其实几乎所有的状语从句都可以变成独立主格或分词结构，时间状语从句，原因状语，条件状语等。例如条件状语从句：If such is the case, you should apologize to her. 如何变成独立主格或分词结构呢?学会下面的口诀，如果你的作文中有状语从句，马上可改成独立主格或分词结构这个最大的亮点。

口诀：一去，二看，三改。一去：去连词;二看：看主语;三改：改分词。

If such is the case, you should apologize to her.按照这个口诀来改，第一步，去掉连词if;第二步，看前后两句话的主语，前后主语不一致，所以要改成独立主格;第三步，改分词，is 变成分词是being，所以最后变成Such being the case, you should apologize to her.就变成了独立主格。

如果前后两句话主语一致，就变成分词结构，例如2005年高考书面表达中的一句话Because I am a student, I’d like to know the price for students. 改成Being a student, I’d like to know the price for students.其他想表达状语从句的时候几乎都一样。所以想表达由于，因为，如果等都写成独立主格或分词结构会让阅卷老师多给几分。

以上技巧有语文迷小编整理，看过后你真的学到了吗?

Since we were born as a little baby, we get help from others all the time.

Our parents raise us, our teachers teach us and our friends company us.

Therefore, it’s important for us to be grateful to those people who give us a

hand. Being grateful is a way to show them our appreciation and our love. No one

in the world is supposed to love us without any conditions. Moreover, Being

grateful to others and to what you get can lead you are ready to help others,

too. I think this is the most important impact on people that being grateful. If

we are all show our appreciation to others and then help others, we could build

a friendly and harmonious society.

To my hometown, where is not wide, fame is not too big, but in my heart, it is better than any other big cities, because of the change of the home is too big, it become more and more beautiful, more become more lovely.

Considerable hometown scenery also more and more, such as huang taishan parks. Was a barren loess slope, the mountain of trees, let a person see the very boring.

Artificial lake, the original is a river, the river used to shampoo in the rainy season, flooded farmland, villages. Downstream of the upstream reservoir, lake water, into the lake big lakes, this is no disaster. There, you can swim, can fishing, billow above during the day, night glittering and moving, is really fascinating.

Farther away, said the Aries valley. Here the mountain is the Great Wall, mountain spring water, the scenery pleasant. If you want to climb the Great Wall, you may wish to try first to Aries valley, you dont look down upon it, is also very high, it is not easy to climb.

I forgot to tell you, my hometown is - qianan region, had the opportunity to shoot, must it will make you linger!

要说我的家乡，地方不算广，名气也不太大，但在我心中，它比任何大城市都好，因为家乡的变化太大了，它越变越美，越变越可爱。

家乡的可观风景也越来越多了，比如黄台山公园。原来就是一片荒芜的黄土坡，山上的树也不多，让人看了很枯燥。而现在，已变成美丽的风景区，有小山，有小树林，有花坛，有草地，有湖水……一年四季都各具特色，美丽无比。人工湖，原来也只是一条河，这河以前经常在雨季发水，淹没农田、村庄。经上游修水库，下游修湖蓄水，变成了西湖似的大湖泊，从此没有灾害了。在那，可以游泳，可以垂钓，白天水光潋滟，晚上波光动人，真是令人陶醉。

再往远一点说，白羊峪。这里山上有长城，山下有泉水，风景宜人。如果你想爬长城，你不妨先去白羊峪试试，你可别小看它，也很高的，爬上去不容易哦。想玩水的话，也可来白羊峪，这里有一条大泉水河，在水面上划船赶鸭子，没看过吧，很有趣呢。还可以从羊头里接泉水，纯天然，很干净的。

几年来，家乡的楼房越盖越高，道路越修越宽越平，就连农村也搞道路硬化，成了真正的文明生态新农村。你就是一个地地道道的本地人，出门在外三五年，回家也怕找不到路。

家乡存储了我快乐的时光，给我留下了深刻的印象。家乡的美丽风景给我们带来欢乐。每次想的家乡，我就不禁想起童年在家乡过的快乐时光。这样美丽的家乡，难道不使我去爱它吗?

忘了告诉你了，我的家乡是——迁安，有机会一定要来呦，它会让你流连忘返的!

by the time children enter school, they’ll have spent up to one-third of their waking hours in front of tv. the enormous influence of television is just beginning to be realized. while many parents take television as an electronic baby-sitter, they neglect the fact that television may be more harmful than it is beneficial to children.

those who encourage small children to watch television claim that many programs for children on tv are helpful to develop children’s interest and enrich their knowledge. they also argue that preoccupied with tv programs, children are prevented from doing mischief. although at a first glance these arguments sound true, the behavior of some children doesn’t seem to prove them.

in the first place, programs for children are not always beneficial to them. one science fiction serial keeps telling about some supernatural beings who can fly and always fight against evildoers. after watching several episodes, a small child was so enchanted that he imitated the heroes and “flew” from his room on the second floor. there are also reports of children running away from home to the mountains to practice martial art. these incidents are naturally credited with tv programs for children.

further, being preoccupied with tv programs is not a good way for avoiding mischief. in the days before tv, parents used to gather together with their children, telling stories or reading poems to them. the communication between parents and children was thus better, so it was easier for children to understand what was good conduct.those who approve of children’s watching tv neglect television’s bad effects on children. firstly, children are surrounded and bombarded by commercials for toys and foods. they are tempted into becoming consumers. they earnestly ask their parents to buy things which they do not really need. as a result, the parents are in a financial dilemma, and the children themselves always become victims of bad products because of false advertising.

another bad effect of television is that children are over-exposed to violence. they watch hours of murders, fights, and crimes every week, with no adult around to tell them that life is not like that most of the time. the effect of the heavy dose of violence is to suggest to children that violence is an ordinary way of life, and that shooting and cheating are ways to success.most serious of all, children who often watch tv are becoming passive. they just sit back and let things happen to them. children are inventive; they have the ability to imagine a whole world of their own. but what happens when their imagination is not needed, when tv does all the imagination for them? obviously, these children are not going to grow up as inventive and imaginative as their parents, for they have been robbed of creative impulses by television.

to sum up, children’s indulgence in television is harmful. the problem, nevertheless, is not one of prohibition. parents should supervise and guide their children’s watching tv instead of parking them in front of the tube, hoping it will act as a baby-sitter.

I live in a city, since I was small, I witnessed all thethings happened in this city.

我住在一个城市，当我很小的时候，我目睹了发生在这个城市的一切事情。

Now, in my eyes, after so many years, the city haschanged so much.First, the transportation hasbecome fluent.

现在，在我眼里，交通变得便利。

Many years ago, there were less bus stations, peoplealways needed to changed their lines by many cars.

很多年以前，公共汽车站点很好，人们总是需要通过换车来改变路线。

But now, almost all the places can be reached by bus, people dont need to change the line.

现在，几乎所有的地方都可以通过公交车到达，人们不用改变路线。

Second, the buildings are enlarging, this reflects the citys economy develops fast.

第二，建筑正在扩大，这反映了一个城市经济的快速发展。

Indeed, I can go to many newly built public places to have fun, some are for children, some arefor the old,

确实，我可以去很多新建的公共场所玩，一些是给孩子的，一些是给老人家的，

all of these are good for peoples communication. The citys change reflects people keep pacewith time.

所有的这些对于人们的交流是有用的。城市的改变反映了人们与时俱进。

从世界各地来看，读书节已成为当代社会的文化景观，而且是最近20年的新风潮。不过，现代意义上的第一个“读书节”，最早可追溯到1926年西班牙国王首次设立的“西班牙自由节”，并把伟大作家塞万提斯的生日10月7日作为这个节日的庆祝日。

From all over the world, Reading Festival has become the cultural landscape of contemporary society, and it is a new trend in recent 20 years. However, the first "Reading Festival" in the modern sense, the earliest can be traced back to 1926, the king of Spain for the first time to set up a "Spanish freedom festival", and the great writer Cervantess birthday in October 7th as a celebration of the holiday.

1930年庆祝活动移到4月23日――塞万提斯的忌日，碰巧这一天也是加泰罗尼亚地区大众节日“圣乔治节”。传说中勇士乔治屠龙救公主，并获得了公主回赠的礼物――一本书，象征着知识与力量。每到这一天，加泰罗尼亚的妇女们就给丈夫或男朋友赠送一本书，男人们则会回赠一枝玫瑰花。由此相沿成习，如今每到这一天，书籍减价10%，玫瑰花的价格则陡然上涨。

Celebration on 1930 to April 23rd -- the anniversary of the death of Cervantes, to this day is also the Catalonia area public holiday "St. Georges day". The legend goes that the knight George slew a dragon and saved a princess, and was granted a gift in return: a book, representing knowledge and power. Every year on this day, Catalonia women will give a book to their husband or boyfriend, the men will give a rose. Thus become a custom through long time usage, and now every day, the book price by 10%, prices rose sharply rise.

世界读书日就来源于此。巧合的是，这天是著名作家塞万提斯、莎士比亚、维加3位著名文学大师的辞世纪念日，又是美国作家纳博科夫、法国作家莫里斯・德鲁昂、冰岛诺贝尔文学奖得主拉克斯内斯等多位文学家的生日。巧合之外，则是人们对书籍的热爱和对阅读重要性的深层认识。主旋律都是一样的：无论是年老还是年轻，无论是贫穷还是富有，无论是患病还是健康，都能享受阅读的乐趣，都能尊重和感谢为人类文明作出巨大贡献的文学、文化、科学思想大师们，都能保护知识产权。

World Book Day comes from this. Coincidentally, this is the famous writer Cervantes died, Shakespeare Vega, 3 famous literary masters of the day, and Nabokov, French writer USA writer Maurice de Rouen, Iceland Nobel prize winner Laks Ness and many other writers day. Coincidentally, is that people love of books and a deep understanding of the importance of reading. The main theme is the same: whether old or young, whether rich or poor, whether it is sick or healthy, can enjoy the pleasure of reading, respect and gratitude can make great contributions to human civilization, literature, culture, scientific thinking gurus, can protect the intellectual property rights.
