hours a day in studying. When I was tired, I watched TV or listened to music for

a little while. But It was a big pity that I couldnt go to the see cinema. In

addition, I had to refuse all the invitations of friends and relatives. I only

called them or sent messages in the New Year’s Eve. I desperately hoped that

there is no exam but I know it’s impossible. The only thing I can do is to study

hard to get good scores and can be admitted to Tsinghua University.

Since I was very small, my parents sent me to learn painting. They thought

I could understand art and mastered one skill. This experience brings me the

sense of art. I have my own understanding of it.

On the one hand, art is an important way to express peoples opinion. When

we see the pictures, the difference between classical and ordinary paintings

lies in the thoughts. The famous artists implant their ideas in the pictures,

which are admitted by the public, so the value of arts can be seen. Some famous

artists expressed their unique opinion and gives arts great meaning.

On the other hand, art is not only from works, but also from life. For

example, my mother cooks the delicious food. Everybody speaks highly of her. So

her food brings people great happiness, which makes the food an art for me.

Whats more, my friends is good at communicating. The way she talks can convince

other easily, so I call the way she communicates as an art.

In all, for me, art is around. It brings people a way to see the world or

makes our life wonderful.

My House Dog

I’m a dog lover, because dogs are tame, friendly and easy to communicate with. I have kept one in my house, whose name is Chocolate. She is covered with brown curly hair and looks like a Teddy Bear. Now we have been living together for two years, so I’m very familiar with her characteristics. When she is hungry, she often barks loudly. At that time, I begin to realize that it’s time to feed her. She is keen on beef and fish. Sometimes, she also eats some rice.

我是一个爱狗的人，因为狗是很温顺，友好，也很容易交流。我在我家养了一只，它的名字叫巧克力。她的毛是棕色的卷毛，看起来就像泰迪熊。现在我们已经一起生活了两年了，所以我很熟悉她的性格。她饿了，她经常会大声吠。那个时候，我就会开始意识到是时候喂她了。她喜爱吃牛肉和鱼。有时候，她也吃一些米饭。

Every day when I come home, she always jumps up to me happily, with her tail moving. She seems to be my best friend. As time goes by, the relationship between us becomes closer and closer. Therefore, I think her as an important member in my family. I really have the pleasure of her company.

每天我回到家的时候，她都会用她的尾巴开心地跑向我。她就像是我最好的朋友一样。随着时间的流逝，我们两个的关系变得越来越亲密。因此，我觉得她是我们家里很重要的一员。有她在我真的很开心。

中学英语教学大纲中明确指出：“写是书面表达和传递信息的交际能力。培养初步写的能力，是英语教学的目的之一。”在近年的高考中英语写作也占有相当比重。因此，在高中阶段教师应在指导和组织学生进行英语写作上下功夫，在平时教学中应有计划有目的地去训练和提高学生的写作能力。

一、学生能充分认识英语写作的重要性是写作能力提高的必要条件。

英语写作能力的提高需要持之以恒的长期训练。如果学生对写作重要性认识不够，他们就不能积极主动地去配合老师搞好写作训练，甚至产生逆反心理，产生对立情绪，英语写作就会半途而废，达不到预期目的。

在平时教学中，老师要经常性地有意识地对学生进行写作重要性的教育。学生一进入高中就要让他们了解初中和高中英语教学要求的异同。

我给学生找几份中考和高考题，帮助他们了解中考和高考英语试题对基础知识和基本技能要求的相同之处和不同之处，引导他们转变观念，更新和完善学习方法，要让他们了解到英语写作在高考中、实际运用中以及对将来继续学习英语的重要性。

我还联系在过去高考中英语取得优异成绩的毕业生，用书信介绍学好英语的方法，特别是在英语写作方面的成功经验和英语写作对他们当时及后来英语学习的重要性。这些毕业生有很大的感召力，很有说服性，尤其对那些有逆反心理的学生。

二、指导写作应注意的几个问题：

1．教师要有明确合理的教学计划和教学程序，组织系统规范的有序训练。

2．帮助和要求学生养成积极主动地坚持英语写作的良好习惯。

3．坚持循序渐进的训练原则。写作要先易后难，先短后长，先学会运用简单句、并列句，后学会用复合句表达，先写正确句子逐步过渡到围绕一个人、一件事、一个观点去写有中心的文章，由不限定时间到限定时间，由限定时间长到限定时间短，由限定字数少到多……

4．分程度要求。对学生的要求不能一刀切，对学习好的要求要高，对学习差的要求要适当低一些。要避免有些学生轻而易举垂手可得，而有些学生又可望而不可及的情况发生。

5．注意讲评。要经常指出优点，以利模仿，指出缺点，警示避免。

6．鼓励优秀，耐心帮助差生。充分利用板报、专栏进行优秀作文展览，或者也可采用传阅方式进行。但不能放弃或岐视差生，要经常帮助他们树立信心，掌握写作方法和技巧。

7．基础知识和能力并重，听说读和写并举。教师在平时教学中应充分利用一切可以利用的机会启发引导学生提高自己的写作水平。如遇到优秀的句、段或篇提示学生注意欣赏作者的表达法，把它们作为范例，在自己写作中加以模仿和运用。又如遇到英汉表达方法不同之处，提示学生注意英语的正确表达法，切忌出现汉语式的英语。要帮助学生养成正确运用标点符号的好习惯，切忌一点到底的错误方法。

8．要求学生在写作中宁简勿误，不能养成随随便便的习惯，要养成严谨推敲的风气。

三、训练写作的常用方法。

写作训练应考虑循序渐进的原则，采取逐步提高的形式进行。

1．用学过的词、短语或句式，模仿课文中的表达法造句。2．换课文中的人物、时态、语态或体裁等改写课文。3．看图作文。4．填补式作文。5．写课文复述材料或写心得体会。6．将打乱顺序的句子按事件发展的时间顺序或逻辑关系等整理成一篇完整的短文。7．教师给出题目和提纲让学生写作。8．写日记或周记。9．材料作文。教师给出汉语提示让学生用英语表达。

四、注意纠正学生英语作写中容易出现的错误。

学生最初写作时，教师要给予必要的指导，使他们少犯错误。教师还要经常性地例举错误的表达法，提醒学生注意避免。在批阅作文时教师要随时标出学生错误之处，还要随时记录学生所犯错误，把学生的错误加以归类总结，把普遍性的错误提出来，让学生集体改错，使他们的语言表达尽可能地规范正确。

总之，学生英语写作能力在老师有计划的组织和耐心帮助、正确引导下，在学生长期积极密切的配合下是能够得以逐步提高的。

导语：《简·爱》是十九世纪英国著名的女作家夏洛蒂·勃朗特的代表作，人们普遍认为《简·爱》是夏洛蒂·勃朗特“诗意的生平写照”，是一部具有自传色彩的作品。下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

This is a story about a special and unreserved woman who has been exposed to a hostile environment but continuously and fearlessly struggling for her ideal life. The story can be interpreted as a symbol of the independent spirit.

It seems to me that many readers’ English reading experience starts with Jane Eyer. I am of no exception. As we refer to the movie “Jane Eyer”, it is not surprising to find some differences because of its being filmized and retold in a new way, but the spirit of the novel remains----to be an independent person, both physically and mentally.

Jane Eyer was a born resister, whose parents went off when she was very young, and her aunt，the only relative she had，treated her as badly as a ragtag. Since Jane’s education in Lowwood Orphanage began, she didn’t get what she had been expecting——simply being regarded as a common person, just the same as any other girl around. The suffers from being humiliated and devastated teach Jane to be persevering and prize dignity over anything else.As a reward of revolting the ruthless oppression, Jane got a chance to be a tutor in Thornfield Garden. There she made the acquaintance of lovely Adele and that garden’s owner, Rochester, a man with warm heart despite a cold face outside. Jane expected to change the life from then on, but fate had decided otherwise: After Jane and Rochester fell in love with each other and got down to get marry, she unfortunately came to know in fact Rochester had got a legal wife, who seemed to be the shadow following Rochester and led to his moodiness all the time ----Rochester was also a despairing person in need of salvation. Jane did want to give him a hand, however, she made up her mind to leave, because she didn’t want to betray her own principles, because she was Jane Eyer. The film has finally got a symbolist end: Jane inherited a large number of legacies and finally returned. After finding Rochester’s misfortune brought by his original mad wife, Jane chose to stay with him forever.

I don’t know what others feel, but frankly speaking, I would rather regard the section that Jane began her teaching job in Thornfield as the film’s end----especially when I heard Jane’s words “Never in my life have I been awaken so happily.” For one thing, this ideal and brand-new beginning of life was what Jane had been imagining for long as a suffering person; for another, this should be what the audiences with my views hoped her to get. But the professional judgment of producing films reminded me to wait for a totally different result: There must be something wrong coming with the excellence----perhaps not only should another section be added to enrich the story, but also we may see from the next transition of Jane’s life that “Life is like a box of chocolates, you never know what you would get.” (By Forrest Gump’s mother, in the film “Forrest Gump”)

What’s more, this film didn’t end when Jane left Thornfield. For Jane Eyer herself, there should always be somewhere to realize her great ideal of being independent considering her fortitude, but for Rochester, how he can get salvation? The film gives the answer tentatively: Jane eventually got back to Rochester. In fact, when Jane met Rochester for the first time, she scared his horse and made his heel strained, to a certain extent, which meant Rochester would get retrieval because of Jane. We can consider Rochester’s experiences as that of religion meaning. The fire by his frantic wife was the punishment for the cynicism early in his life. After it, Rochester got the mercy of the God and the love of the woman whom he loved. Here we can say: human nature and divinity get united perfectly in order to let such a story accord with the requirements of both two sides. The value of this film may be due to its efforts to explore a new way for the development of humanism under the faith of religion.

Life is ceaselessly changing, but our living principles remain. Firmly persisting for the rights of being independent gives us enough confidence and courage, which is like the beacon over the capriccioso sea of life. In the world of the film, we have found the stories of ourselves, which makes us so concerned about the fate of the dramatis personae.

In this era of rapid social and technological change leading to increasing life complexity and psychological displacement, both physical and mental effects on us call for a balance. We are likely to find ourselves bogged down in the Sargasso Sea of information overload and living unconsciousness. It’s our spirit that makes the life meaningful.

Heart is the engine of body, brain is the resource of thought, and great films are the mirrors of life. Indubitably, “Jane Eyer” is one of them.

保护环境善待地球

众所周知，我们只有一个地球。地球是我们的家园。我无法想象，如果地球消失了，人类该怎样生存。

我们的生活不能离开地球，所以，请善待地球。

现在的空气不是很新鲜，天也不是那样湛蓝。这是为什么？因为有很多人乱砍滥伐，还污染河流。我们在森林里看不见小动物玩耍，也看不见小鱼在水里游泳。

如果长时间都是这个景象，世界末日就会来临。

那么，我们怎样才能保护环境呢？让我来给大家一些建议吧。

首先，我们可以植树。树木可以给予我们新鲜的空气，还可以吸收二氧化碳。

其次，我们可以坐公交去上学或上班,少开车。汽车排放的尾气会污染空气，它对我们的身体没有好处，对地球也没有好处。

这就是我的建议。

今天是世界环境日，让我们一起保护环境，善待地球吧！

We are always educated to be an honest person, especially to our parents. While the fact is that every kid will lie to their parents in their lives. For me, my parents are very strict, I am not allowed to go out at night, because the news always reports the bad incidents happen at night. But night activity attracts me a lot, and my friends like to hang out for fun at night, so I choose to lie to my parents and tell them I am doing my homework with my friends. Now as I grow up, I realize it is not right to tell lies, so I decide to be honest to my parents. Once they realize that I am not a little kid anymore, then I will have my right to do what I want.

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.

Hope Project is a Chinese public service project organized by official organization. It aims to help children go back to school, build Hope Primary School and improve rural conditions in poor regions.

In many poor areas in China, there are many school age children cant go to school because their families do not have enough money.

希望工程是由官方组织举办的中国公益项目。该项目旨在帮助孩子们重返校园，建立希望小学以及改善贫困乡村地区的条件。

在中国，很多贫困地区的适龄儿童由于家里没有足够的钱不能去上学。因此，他们不得不待在家帮助家人做农活。我们常常说知识改变命运。因此，只有学习能够帮助他们走出外面的世界，改变他们的生活，甚至是改变他们家乡贫困的现状。通过希望工程，我们可以收集到资金、书籍以及其他材料以改善贫困的现状。这样一来，孩子们就可以分享更多的资源，学到更多知识。

除此之外，城市里的很多人就有机会和渠道显示他们的善良。最重要且有意义的是他们可以帮助那些极需帮助的孩子们。
