So I’ve improved my life in this way.

高考英语作文需要将有自己的想法，并且掌握好写作的方法，这样英语才能得到高分。

1、审题：审题是做到切题的第一步。所谓审题就是要看清题意，确定文章的中心思想、主题，并围绕中心思想组织材料。

2、进行构思，列出简单的提纲，打造文章之骨架：审好题、立好意后，就要写提纲，打造文章的骨架。文章布局要做好几件事：安排好层次段落，铺设好过渡，处理好开头和结尾。

3、扩展成文：根据字数多少扩展成篇。扩展的内容一定要紧扣主题，千万不要写那些与主题不相关的内容。展开的方式包括：顺序法、举例法、比较法、对比法、说明法、因果法、推导法、归纳法和下定义等。可以根据需要任选一种或几种方式。

在这一步骤中还需注意三方面问题：

1)确保提纲中段落结构的思路与各段主题句的一致性。只有这样，才能保证所写段落不偏题、不跑题。

2)要综合考虑各个段落的内容安排，避免段落内容的交叉。

3)用好连接词，注意段落间、句子间的连贯性。要做到所写文章层次分明，思路清晰，文字连贯，就需要在句与句之间、段与段之间架起一座座桥梁，而连接词起的正是桥梁作用。

在扩展的过程中也有些窍门，以下几点可供参考：

1)在整篇文章中，避免只是用一两个句式或重复用同一词语。英语中存在着极为丰富的同义词，准确地使用同义词可以给读者清新的感觉。同时要灵活运用各种句式，如倒装句、强调句、省略句、主从复合句、对比句、分词短语、介词短语等，从而增加文章的可读性。

2)使用不同长度的句子。如果一个意思用一句话写不清楚的话，通过分句和合句或用两句、三句来表达，增强句子的连贯性和表现力。

3)改变句子的开头方式，不要总是以主、谓、宾、状的次序。可以把状语至于句首，或用分词等。

4)学会使用过渡词。

(1) 递进furthermore，moreover，besides，in addition，then，etc

(2) 转折however，but，nevertheless，afterwards，etc

(3) 总结finally，at last，in brief，to conclude，etc

(4) 强调really，indeed，certainly，surely，above a11，etc

(5) 对比in the same way，just as，on the other hand，etc

5)确定文章用第几人称写，基本时态是什么。使用人称时人物不能张冠李戴或指代不明。

时态要尽量保持一致。

4、检查修改：要检查复核，不要写完了事。

要留时间通读全文，修改可能出现的错误。检查上下文是否连贯，句子衔接是否自然流畅。检验的标准主要是句子是否通畅，该用连词的地方用了没有，所用的连词是否合适，是否有语法错误，主谓是否一致，动词的时态、语态、语气的使用是否正确，词组的搭配是否合乎习惯，是否有大小写、拼写、标点错误等，还有就是注意卷面整洁。

可归纳为：中心突出，主题明确;层次清楚，条理清晰; 表达力强，传情达意;语句通顺，句型多变;过渡自然，衔接紧凑;标点正确，大小无误;字迹清楚，卷面整洁。

"University", a beautiful word, which makes me have much imagination. As

the name "ivory tower" given by people, its a good place to live and study. In

the ivory tower, romantic love just like cherry blossom smiles happily in the

campus.

Many girls have the sweet dream that one day there is a boy who stands

below the windows loud annoucing "I love you", holding a bound of flowers in his

hands. But the most important things is that I can receive the advanced

education systematically, listen to the senior professors experience, attend

many dourses of lectures. To my pleasant, I can be free to spend a whole day in

the library and read every book that Id like, which makes me find the knowledge

is vast considerably. All these let me climb up in the field of science. At the

same time, the people from many parts of motherland get together. Its a big

furnace involved dialects and cluture. Its interesting.

I can find a part time job to experience the life, which is a good way of

contacting society. In short, therere many things waiting for me to learn, and

this is why I come here to be a university student.

水，是人类赖以生存的重要自然资源，是生命的源泉，大地上的每一个生命都需要靠水来成长。水是多么伟大啊，它把自己无私地奉献给需要它帮助的人！但是，水是取之不尽，用之不竭的吗？由于人们大量用水，随意浪费水资源，中国的许多城市都已严重缺水！

据资料显示，地球能够被人类直接利用的淡水资源仅占地球的百分之零点三！沙漠无情地吞噬了许多树木、村庄、田地，这严重影响了人类的经济建设，也威胁着人类的生存！全世界的人们都以经对节约用水，保护水资源引起了重视。我也要为社会出一份力，从自己做起，从身边做起。

每天早上起床，洗脸刷牙都是我们必做的事，它们自然也离不开水。这时候，我们就要用巧妙的办法节约用水！洗脸时，为了节约用水，水只要放脸盆的一半即可洗脸。洗完脸，水可不能到入下水沟，我们把它倒进一个专门装这类水的水桶，以备下次冲洗马桶二次利用。在刷牙时，我们一般都要用普通杯子换三次水。间断地换水刷牙只需用水约3升，而不断地放水30秒，就会用掉约6升的水！一个三口之家每天刷牙两次，一个月就能节约约540升水！看来小小的刷牙只要用上节约用水的办法对社会也会做出大贡献呢！水龙头是我们每天取水的方法之一。它能给我们带来取水便利，相反，当它“生气时”，它也会拿干净的小水滴出气，把它们一个个送进下水管。因此，我们在用完水后一定要拧紧水龙头，随时检查水龙头是否漏水。即使是每天不停地滴一小滴水，一个月也会浪费无法估量的清水！炎炎的夏日，总是让人感到酷暑难熬，每天晚上睡觉前，我们总是要冲一个凉水澡。那么在淋浴时，我们要控制浴头的水量，要间断冲洗，如果长时间连续冲洗也会浪费许多清水……这些都是我们在洗漱时节约用水的窍门，那么当大人们在为我们准备丰盛晚餐前，他们又有什么节约用水的妙招呢？原来啊，淘米后的水和洗完菜的水也有自己的用处，它们可以用来浇花、擦椅子、拖地……听大人们说，淘米后的水用来浇花能使花草更好地成长！听我介绍了这么多，看来大家都知道用过水有许多妙用了吧！你们也可以试试这些妙招，相信每个人都成为光荣的节水卫士！

多惜水，少废水，让我们一起节约用水！我相信，有13亿中国人民的共同努力，水资源将会越来越丰富，祖国一定会更加美丽、富饶！

A Day in the Zoo

There has been a long time for my family not to go out for the activity, because my father is busy all the time. But last week, my father finally finished his project, so that he could take a rest for some time. My father advised us to go to the zoo, I was so excited, because I hadn’t seen many animals in my life. In the zoo, there were so many people, it was so lively. I saw the monkey, the giraffe and so on. I saw these animals in the TV usually, but I saw them in front of me that day. The peacock impressed me so much, it looked homely when it laid down the ground, but when it stood up and opened the wings, it was so gorgeous. People said peacock was proud, indeed, it would not please people. I had a good time in the zoo.

对于我的家人来说，我们已经有很长一段时间没有外出活动了，因为爸爸总是很忙。但是上周，我的爸爸终于完成了他的项目，所以他能休息一段时间。爸爸建议我们去动物园，我很兴奋，因为我目前还没有看到过很多动物。在动物园里，有很多人，非常热闹。我看到了猴子，长颈鹿等等。我平常在电视上看到这些动物，但是那天我亲眼看到了。孔雀给我的印象很深刻，在它躺在地上的时候，看起来很普通，但是当它站起来，打开翅膀，是那么的美丽。人们说孔雀是傲慢的，确实，它不会取悦人们。在动物园里我度过了一段美好的时光。

ChenMo is my desk mate who is a good student in the eyes of classmates andteachers.

She is the first one to get to school every day.

Usually, she spendshalf an hour in learning English that takes us much to remember vocabularies andread the articles. Moreover, she not only focuses on her own study, but alsohelps other students in need.

Classmates like asking her for help, because sheis always ready for help.

However, I prefer to regard her as my friend ratherthan desk mate.

We communicate with each other frequently after class.

We discussour study as well as share our lives. She is desperately interested in playingbadminton, so do I. We would play badminton very Friday after class, whichhelps us relax ourselves as well build our body. It’s so great to have a deskmate that has interest in common.

陈茉是我的同桌，她是老师和同学眼里的好学生。她每天都是第一个到教室的。

通常，她会花半个小时学习英语。英语需要花比较多的时间去记单词和读课文。陈茉不仅专注于自己的学习，也积极帮助其他有需要的同学。

同学们喜欢找她帮忙，因为她总是那么乐于助人。

但是，在我眼里，她不仅是我的同桌，更是我的朋友。课后，我们经常相互交流，讨论学习问题或是分享彼此的生活。她很喜欢打羽毛球，我也一样。我们常常会在周五下课后打羽毛球，这不仅能使我们得到放松，也有益于我们的身体健康。能有一个拥有相同兴趣爱好的同桌真是太好了。

The older I grow, the more I appreciate children. Now, at my 80th birthday, I salute them again. Children are the most wholesome part of the race, the sweetest, for they are freshest from the hand of God. Whimsical, ingenious, mischievous, they fill the world with joy and good humor. We adults live a life of apprehension as to what they will think of us; a life of defense against their terrifying energy; a life of hard work to live up to their great expectations. We put them to bed with a sense of relief---and greet them in the morning with delight and anticipation. We envy them the freshness of adventure and the discovery of life. In all these ways, children add to the wonder of being alive. In all these ways, they help to keep us young.

i do the normal routine, eat dinner, clean the house, write-the usual stuff. and then i lay down hoping to fall asleep quickly so my new day will hurry up and arrive. a new day with a brand new sun. but as i lay there and wait for the world to turn half way around, i think about her. and sometimes i smile, and sometimes that smile will turn into asnicker, and then often that snicker will turn into a burst of laughter.

我按平时的规律吃晚餐、打扫屋子、写作--做着日常事务。然后我躺下，希望能快点入睡，新的一天就能快点到来--拥有新生太阳的崭新的一天。可当我躺在那儿，等待着世界的日夜回转时，我想到了她。有时我会笑起来，有时那微笑变成了窃笑，然后窃笑又常常变成爆笑。

大家都知道水是生命之源，一旦没了水，人就无法生存。地球淡水资源很缺乏，据估算淡水仅占所有水资源的2.5%, 而且淡水的70%是冰,真正可以直接利用的江河湖泊水只占总量的千分之三。我国华北大部分地区常年缺水，全国有400多个城市因气候和环境污染，供水不足，连干净的饮用水都喝不上。

尽管我国部分地区短期内有充分的水资源，但是专家预测，2030年中国人口达到16亿，在充分考虑节水的情况下，预计用水总量达到7000亿至8000亿立方米，已接近全国可利用的水资源总量上限。我国水资源的开发难度极大。

所以，同学们，让我们行动起来吧，从身边的小事做起，利用好现有的水资源，杜绝浪费。不然，最后一滴水，就是我们自己的眼泪。

Today is the 21stcentury, as the highly developed of technology, we

facilitate our life with all kinds of newly invented products, such as computer,

digital camera and so on. The technology products indeed brings us convenience,

the old way of doing things has been challenging. Before, people like to write

letters to say hi to others or send letters to give people information, while

today, people can use smart phone or computer to call others quickly, that saves

a lot of time. Does the way of writing letters will be kicked out and disappear?

Well, on my opinion, though people like to use the new technology, letter still

has its charm. Writing letters means someone is in sincere attitude, the one who

receives the letter will be touched deeply. Sometimes message is hard to use

phone to explain, then letters will be used. In a word, writing letter will be

not out of day.

Dear Friend,

How have you been recently? I miss you very much. Do you still remember

me?

To be honest, Im honored to make friends with you. I still remember the

days when we were together. As far as I know, you are the kindest person in the

world. Once we were together, you always treated me as if I were your dear

brother, so I was grateful to you in my heart. After you leaving, I always

thought of you. Next time we have a chance to see each other, I will say "thank

you" to you. Thank you for your kindness. Now I have got the meaning of my

life.

Although we are in two different places now, we are still together, because

we are always heart to heart. I believe we can see each other again. Since we

are always close friends as well as dear brothers. Because of you, my life is

always so significant. Wherever I am, I will pray good luck for you.

Last but not the least, I hope you can make it and have a bright

future.

Sincerely yours,

Jason

Water is the source of life for people, something that is necessary for the growth of all things. Water, everywhere, home, nature, and we always think it does not matter, some water! Waste is not how it will be. But you are wrong, the water has been wasted by you.

When we go to the hotel to eat, whether to wash their hands found a taps did not shut, there are ticking water, then, how do you do? If nothing had happened, or to save this dripping and go up and turn off? If you close, then you save some water, but if you did not close, you know whether you have a small move, and how much water wasted. Maybe you wasted very little, but how many people in the world at this time like you, so that there will be more water to go.

On the sixth grade, the moral teacher out of a question, the worlds most lack of resources, I and students filled with confidence in the water. And this is wrong, we puzzled, the teacher replied: "is fresh water." We suddenly realized. This is right, the most flawless water, there are numerous water in the sea, and it is not fresh water.

There is an ad on the TV, a fax machine constantly in the delivery of paper, and finally came out a lot of wood fragments. How much paper we waste, paper is made of trees, even if each one, half of the waste, that the world people and how much waste it? Wasted paper is cut off hundreds of millions of trees? If each person to save some, to eliminate waste, then there are hundreds of millions of trees were saved?

We are always looking at other people wasting water, paper, criticizing others, and whether we think of ourselves. Do not you waste yourself? So, save it, in order to keep the trees long, so that the water of life stay in nature. Together to promote conservation, call the people, save every drop of water, every piece of paper, so that the world more than a tree, more than a river!

早上，我刷牙时忘记关水 龙头，妈妈看见了，指责我说 ：“怎么这么不节约水呢？“我不以为然地说：“浪费点水算 什么，我们家又不是交不起水 费！”这时，妈妈语重心长地说：“孩子啊，你算算你每天刷牙两次，如果每次开 着水龙头刷牙大约用180秒， 假如每10秒流失的水是500毫 升，那你每天浪费多少毫升水？一年约365天又将浪费多少水呢？”我仔细地算了算，我每天因刷牙流失水毫升，一年约浪费毫升水。也就是6570升。 妈妈又告诉我：“如果你们全校同学都这么不节约，那该多浪费呀！“是 啊，我们全校近600人都像我这样刷牙，一年就会白白损 失升水！真是不算不知道 ，一算不得了呀！我为我浪费水资源的举动非常后悔。

这真是数学数据让我明白了节约用水的道理呀！同学们，从我做起 ，从身边的小事做起，珍惜我们有限的水资源吧！

一天早上，天气晴朗，我和爸爸去小区的公园里锻炼身体。走着，走着，当我们经过花坛边的一个水龙头时，我惊讶地发现：水龙头没有拧紧，水正在一滴一滴地往下流，地上已经有一大滩水了。我心想：如果一直让水不停地往下流，那多浪费水呀!而且，我们中国是一个缺水的国家，不少边远山区缺乏水，甚至影响到了人们的生活，我们现在有水可以用，就更应该珍惜了。我们老师说过：“节约用水，人人有责。千万不要让最后一滴水变成我们的眼泪!”于是，我就毫不犹豫地踩过水塘，伸出手，把水龙头用力地拧紧，直到水龙头不滴水为止，我这才安心地离开，脸上露出甜甜的笑容。这时，一阵微风吹来，吹动着我胸前的绿领巾，好像在夸奖我是个节约用水的好孩子。

爸爸在旁边一直看着我的一举一动，他高兴地伸出大拇指，也夸奖我是一个会节约用水的好孩子。

Once Chairman Mao said one is never too old to learn, his famous words inspire people to keep learning all their lives. Since we are small, we study at school, then we have to learn until we are at college, after graduate from college, we finish our education in the school.

Then the new stage comes, we start to work, making money, learning knowledge seems unnecessary to us.

This is totally wrong, we learn all the time, even we are out of school, we have lessons from life.

Life is a big topic, we have to learn it all the time. We have to deal with trouble, learning to make friends and accept fail.

All these things we will not learn at school, we have to learn by ourselves, we are students and teachers. If you think you finish learning after school, you are narrow minded.

毛主席曾经说过“一个人要活到老学到老”，他的著名话语激励着人们终身学习。

当我们还小的时候，我们在学校学习，然后直到大学前，我们都要学习，大学毕业后，我们完成了在学校的学习。然后新的阶段到来，我们开始工作，挣钱，学习知识似乎不必要了。

这是完全错误的，我们一直学习，即使不在学校，我们学习生活。生活是一个大主题，我们不得不一直学习。我们要处理麻烦，学着交朋友和接受失败。所有的这些东西我们都不会在学校学到，我们必须自己学习，即是学生也是老师。如果你觉得你出了学校后就完成了学习，你的思想就很狭隘了。

总之，正如谚语所说的，“做最好的自己，因为那些都是你的。”自信是我们生活中不可缺少的一部分。

[高中英语作文：自信心

在很久以前，恐龙灭绝的时光里诞生了人类这个全新的名词，这件事总是让人情不自禁地开始猜想，在很久以后人类如果灭绝了还会有更高层进化的生物出现吗?

答案是肯定的。但是由于现在人类的大肆破坏，浪费水资源，我想就算真的有那种生物出现，也无法适应这种浓雾笼罩、水流枯竭的环境。

地球已经不是以前的地球了，她失去了以往的神采，也没有足够的乳汁来喂养我们。

总是听以前的人说，当时的河流是多么清澈，人们也没有现在这样焦虑。节约用水应该成为地球人最关注的一个重要点，因为水资源的枯竭已经严重影响到了全世界人民的日常生活。由于世界人口在不断膨胀，水资源成反比在不断枯竭，就拿我国来说，中国是全球13个人均水资源最贫乏的国家之一。虽然淡水总量为28000亿立方米，但人均资源只有2200立方米。仅仅是世界平均水平的1/4，在世界上名列271位。这是多么让人感慨而又惊悚的数字。

看到这里，你肯定会问，那我们怎么保护仅有的水资源呢?世界各地都已经采取适当措施，例如美国华盛顿市曾出台过临时法律，禁止人们在某一时间段内给自家草坪浇水，发现后立即罚款。亚洲唯一发达国家日本则是无论政府、企业还是公共场所，都贴有“节约用水”的标识，公共厕所甚至有那种红外线感应的节水装置。当然，我们不仅仅要向缺水国家学习，不缺水的国家做法更让我们反思：在德国，许多德国家庭会将煮面水省下刷油碗，洗衣服的水用来再拖地。

“Watershapeslife.Protectoursources.”这是一家外国杂志上提醒大家节约用水海报上的标语，呼吁着大家去保护地球上的水资源。请随我一起，捍卫水资源的未来吧!这也是在捍卫人类的未来，这个星球上所有生物的未来。

What is healthy diet? To the most people, healthy diet means more green foods, no junk foods. The green food is those pollution-free, high quality and nutrient food, including the organic vegetables and meats, fruits, eggs and so on. The meals of healthy diet should be cooked with fewer salt and oil. And the junk food is those low nutrition, high calorie, processed food with much salt or oil, such as the fries, fried chickens, salted eggs and so on. These foods will cause one get weight and increase the risk of many diseases. We should keep a healthy diet, abandon the junk food to keep ourselves healthy.

什么是健康饮食?对于大多数人来说，健康饮食就意味着多吃绿色食品，不要吃垃圾食品。绿色食品就是那些无污染、高品质和营养的食物，包括有机蔬菜和肉类、水果、鸡蛋等等。健康饮食的膳食应该用更少的盐和油制作。而垃圾食品是指那些低营养、高热量、再加工的高盐重油食品，例如薯条、炸鸡和咸蛋等等。这些食品会导致一个人发胖，并增加疾病的风险。为了保持健康，我们应该保持健康饮食，抛弃垃圾食品。

水，是生命的源泉，是生活中不可缺少的重要东西，我们应该珍惜地球上的水资源。

水，这可是大家平常再熟悉不过的东西了。地球表面有2/3是被水覆盖着，浩瀚的海洋，滔滔长河，星罗棋布的湖泊，把地球装扮得秀丽多彩。对于生命来说，水是生命的成因，一个成年人身体中的2/3是水，血液中水占90%，甚至连骨头里也含有1/5的水份。一个正常人，如果没有任何食物而有饮水的条件下，可以成活20-30天，但如果没有了水，最多只能活一个星期星期，所以人类离不开水。

可是大家知道吗，水这一对我们人类最重要的东西却在渐渐离我们远去，据有关资料统计，地球上总水量为13。6-13。9亿立方千米。其中海水占总水量的97。3%，淡水仅占可怜的2。7%，土壤、大气、生物中也含有一定量的水分。而在淡水中，77。2%是以冰川、冰帽和冰盖的形式存在的，无法直接利用;另外有22。4%是深层的地下水，要开采使用所花费的任劳代价太高，地面上的河流、湖泊及浅层地下水是我们可以利用的，仅占总水量的0。32%，这个百分比虽然很小，可利用的而且水还可以再生，可是为什么它却成为了当今世界上最关注的话题，因为有一些水源受到污染，不宜使用，我国是一个贫水国，所以珍惜水资源更是势在必行。
