How to protect the environment

Good environment can make people feel happy and fit . To improve the environment means to improve our life.

We should plant more trees and flowers around us . We shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air.

Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment.

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。递进furthermore，moreover，besides，in addition，then，etc ;转折however，but，nevertheless，afterwards，etc ;总结finally，at last，in brief，to conclude，etc ;强调really，indeed，certainly，surely，above a11，etc ;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。

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

"Bumper harvest, bumper harvest!"!" Cried one of the fishermen, happily

jumping up like a child. After a while, the full cabin fish alive and kicking,

calm sea filled with coming from all sides of the fishermens

laughter.........

Now, like this "fish and shrimp full cabin" scene has been very rare. In

todays market, is the most common fish pound at least to dozens of yuan, more

serious pollution of the ocean, the ocean resources gradually dried up, seafood

production, prices rise, it illustrates this point?

In the ocean of natural calamities and man-made misfortunes emerge in an

endless stream today, human pollution is often not from the original intention,

but it is caused by the unexpected effect. The British Petroleum oil, because

the drilling platform explosion, caused by the oil spill in the Gulf of Mexico,

to 9900 square kilometers of sea water is seriously polluted, so that tens of

thousands of seabirds soaked in oil to move, die in hunger and misery, makes

countless fish poisoning death; and the Japanese earthquake and tsunami

triggered a nuclear leak the marine pollution is more serious......

The sea is so vast that it is because the rivers and streams flow into the

Yangtze River and then run into the sea. If we do not solve the pollution

problem from the source, then no matter how people clean up the sea, there will

always be sewage flowing into the sea, and all the efforts will be futile. Now,

streams and streams are often seriously polluted, or they become places where

people dump rubbish or are loaded with pesticide cans. Finding a clear stream in

an inhabited area can be very difficult today!

In any case, the protection of the oceans can not be achieved by individual

forces, and the protection of the oceans depends on the joint efforts of all

mankind. I do not want one day in the future, our descendants can only imagine

the image of the vast and wide sea.

This is not only the wish of a pupil, but also the wish of all mankind,

isnt it?

1. It was the first day of our summer holiday. All of us were very happy. Why? Because we have one months to do things we love to do. We are free.Although we have some homework. But we can finish them in several days. And the rest time we can make good use of. My god! We have been very tired after hard studying. In winter holidays, I want to have full sleepand eat good food in order to replenish myself. Last but not the least, I will have a good rest.

【导语】英语写作是中考中检测学生语言应用能力的最重要部分。提高中考写作水平，需要有效的训练。下面关于英语作文的写作方法，一起来阅读下文吧!

学生写作时，如果语句平平，只选用一些普通的、直截了当的词，那么，这样写出来的文章根本没有可阅读行，就像是一碗没有油盐酱醋面条一样，让人提不起一点精神和看下去的欲望，呆板、单调，没有可读性。如果一篇文章要让读者有可读性、有深度，同学们更应该掌握一些高级点词和语句来装饰你的文章，突出这篇文章的彩头，使文章增添文采，给读者以不一样的感受。具体方法可以参照下面的语句：

1. 画龙点睛，一篇文章的开头很重要。

在通常情况下，英语句子的排列方式为“主语+谓语+宾语”，即主语一般都会在谓语前面。但若根据情况适当改变句子的开头方式，比如在文章的开始的时候写一些倒状语句或以状语为起始语句的开头，这样子的文章更具表现力和感染力。如：

(1) There stands an old temple at the top of the hill.

→ At the top of the hill there stands an old temple.

在小山顶上有一座古庙。

(2) You can do it well only in this way.

→ Only in this way can you do it well.

只有这样你才能把它做好。

(3) A young woman sat by the window.

→ By the window sat a young woman.

窗户边坐着一个年轻妇女。

2. 避免重复使用同一词语

为了使表达更生动，更富表现力，同学们在写作时应尽量避免重复使用同一词语来表示同一意思，尤其是一些老生常谈的词语。如有的同学一看到“喜欢”二字，就会立刻想起like，事实上，英语中表示类似意思的词和短语很多，如 love, enjoy, prefer, appreciate, be fond of, care for等。如：

I like reading while my brother likes watching television.

→ I like reading while my brother enjoys watching television.

我喜欢看书，而我的兄弟却喜欢看电视。

3. 合理使用省略句

合理恰当地使用省略句，不仅可以使文章精练、简洁，而且会使文章更具文采和可读性。如：

(1) He may be busy. If he’s busy, I’ll call later. If he is not busy, can I see him now?

→ He may be busy. If so, I’ll call later. If not, can I see him now?

他可能很忙，要是这样，我以后再来拜访。要是不忙，我现在可以见他吗?

(2) If the weather is fine, we’ll go. If it is not fine, we’ll not go.

→ If the weather is fine, we’ll go. If not, not.

如果天气好，我们就去；如果天气不好，我们就不去了。

(3) She could have applied for that job, but she didn’t do so.

→ She could have applied for that job, but she didn’t.

她本可申请这份工作的，但她没有。

4. 适当运用非谓语结构

非谓语结构通常被认为是一种高级结构，适当运用非谓语结构，会给人一种熟练驾驭语言的印象。如：

(1) When he heard the news, they all jumped for joy.

→ Hearing the news, they all jumped for joy.

听了这消息他们都高兴得跳了起来。

(2) As I didn’t know her address, I wasn’t able to get in touch with her.

→ Not knowing her address, I wasn’t able to get in touch with her.

由于不知道她的地址，我没法和她联系。

(3) As he was born into a peasant family, he had only two years of schooling.

→ Born into a peasant family, he had only two years of schooling.

他出生农民家庭，只上过两年学。

5. 结合使用长句与短句

在英语写作中，过多地使用长句或过多地使用短句都不好。正确的做法是，根据实际情况在文章中交替使用长句与短语，使文章显得错落有致，这样不仅使文章在形式上增加美感，而且使文章读起来铿锵有力。如：

At noon we had a picnic lunch in the sunshine. Then we had a short rest. Then we began to play happily. We sang and danced. Some told stories. Some played chess.

→ At noon we had a picnic lunch in the sunshine. After a short rest, we had great fun singing and dancing, telling jokes and playing chess.

中午我们晒着太阳吃野餐。休息一会儿后，我们唱的唱歌，跳的跳舞，还有的讲笑话、下棋，大家玩得很开心。

6. 适当使用短语代替单词

(1) He has decided to be a teacher when he grows up.

→ He has made up his mind to be a teacher when he grows up.

他已决定长大了当老师。

(2) He doesnt like music.

→ He doesnt care much for music.

他不大喜欢音乐。

(3) He told me that the question was now under discussion.

→ He told me that the question was now being discussed.

他告诉我问题现正正在讨论中。

7. 恰当套用某些固定表达

(1) He was very tired. He couldn’t walk any farther.

→ He was too tired to walk any farther.

他太累了，不能再往前走了。

(2) The film was very interesting. Both the teachers and the students liked it.

→ The film was so interesting that both the teachers and the students liked it.

这电影很有趣，学生和老师都很喜欢。

(3) Your son is old. He can look after himself now.

→ Your son is old enough to look after himself now.

你的儿子已经长大，可以自己照顾自己了。

8. 尽量使句子带点“洋味”

(1) Dont worry. Be bold and try it, and youll learn it soon.

→Dont worry. Just go for it, and youll get it soon.

别担心，大胆试一试，你很快就会学会的。

(2) Thank you for playing with us.

→Thank you for sharing the time with us.

谢谢你陪我玩。

9. 综合使用各类所谓的“高级”结构

(1) Now everyone knows the news. I think Jim must have let it out.

→ Now everyone knows the news. I think it must have been Jim who has let it out.

现在人人都知道这消息了，我想一定是吉姆把它泄露出去的。

(2) We had to stand there to catch the offender.

→ What we had to do was (to) stand there, trying to catch the offender.

我们所能做的只是站在那儿，设法抓住违章者。

(3) If her pronunciation is not better than her teacher’s, it is at least as good as her teacher’s.

→ Her pronunciation is as good as, if not better than, her teacher’s.

如果她的语音不比她的老师好的话，至少也不会比她老师的差。

10. 适当使用名言警句点缀

在写作时根据实际情况恰当地用上一两句名言警句来点缀文章，不仅使文章显得有深度、有智慧，而且会让文章在评分中上一个“得分档次”。如：

(1) As the proverb says, “Where there is a will, there is a way.” Though you fail this time, you needn’t lose heart. As long as you work hard and stick to your dream, you will succeed one day.

(2) There is a proverb goes like this “Life isn’t a bed of roses.” It is ture that it is likely for everyone to meet problems and difficulties in life.

(3) In the modern world, more and more people live alone, which is not so good for our life. It is better for us to make more friends and enjoy friendship. Just as a proverb says, “A near friend is better than a far-dwelling kinsman.”

Last week, my friends asked me to spend the weekend in the house that near

the lake. It is one of my friends’ house, where their families often spend the

holiday together. Though the house was not big, the environment around was

really beautiful. In the daytime, we walked around the lake and appreciated the

beauty of nature. At night, we made some food and barbecued. It was such a happy

time that we sung and danced. We talked about our future thoughts. Before we

went to bed, we watched movies together and discussed the plot. This is the most

wonderful moment for us. We share our happiness and have no annoyance.

Tired of the dull day of the holiday， there was a habit of walking on the street。

Just go out， days of rain， like the night sky in the fog， with a wind chill。 Fortunately， shops on both sides of the street lights to create a warm cold， I suzhebozi towards darkness。 Suddenly cried out in a calm shock eardrum: Hey， man， get up! Go away。 With the sound! found a man crouched in the roof。 The shadow with different differences， people spontaneously gathered in the past。

Then a light house， I looked at the old man shivering body， with disheveled hair， worn underwear。。。。。。 involuntarily shivered。 People around together more， who shouted nature is the owner， but we do not know the origin of the elderly。

Some in the crowd whispering， some cigarette in the limited， some in the head sigh。。。。。。 suddenly I felt a moment of silence。 The mouth parched and tongue scorched after a child shouted: Daddy， grandpa is not cold? yes! everyone seems to be inspired by the what， many people began negotiations with the owner。 Under the watchful eyes of the people， the owner blushed， everyone help homeowners。 To restore the confidence， and the boys to act tough and talk soft helped the old man into the room， a middle-aged man has Fengfenghuohuo beside the restaurant brought in hot surface。

Some people off。 I -- an onlooker chouchushou from his trouser pocket， came back to me naive children， in shame to take a step。

厌倦了假期白日的平淡，于是就有了在街道上散步的癖好。

刚出门，天就微雨，似夜空中的雾，沾满了一身，夜风凉飕飕的。幸好街道两旁的店家灯火给寒冷平添了几许暖意，我缩着脖子走向黑暗。蓦地一声断喝在平静中震荡耳膜:喂，老头，快起来!快走开啊!随着声音在一处屋檐的阴影中发现了一个蜷曲着的老人。伴着不同的差异，人们不约而同地围了过去。

接着屋里的一片灯光，我打量着老人发抖的身子，低垂的蓬乱的头发，破旧的衣裤。。。。。。不由地打了个寒颤。周围的人越聚越多，叫喊的人自然是房主，但大家都不知道老人的来历。

人群之中有的在窃窃私语，有的在有限地点烟，有的在摇头叹气。。。。。。我忽然感到口干舌燥了。片刻沉默后，一个童音在嚷:爸爸，老爷爷不冷吗?是啊!大家似乎是受到了什么启发，好些人开始跟房主交涉，众目睽睽之下，房主涨红了脸，:大伙帮个忙。房主恢复了自信，和几个小伙软硬兼施地把老人扶进了房内，一个中年人已经风风火火地在旁边的饮食店中拿来了热腾腾的面。

好些人散去了。我--一位看客，从裤兜里抽出手，耳边回响起幼稚的童音，在羞愧中重新迈开脚步。

词汇拼写错误较为严重，词汇选用上会有不当的情况。

应对策略就是平时阅读过程中注意单词拼写，关注单词使用语境，多积累高级词汇和句型。

语法掌握不好，句子的基本构成主谓结构掌握不清。

Due to the fact that the mental state, we have to keep a balance between the physical and the mental.

这句话中，due to the fact that后面需要接一个句子，而上句中只是一个名词性短语，所以错误。另外，between...and...需要连接两个名词短语，上句中形容词physical和mental后缺少名词性成分。改正为Due to the fact that the mental state plays a significant role, we have to keep a balance between the physical well-being and the mental health.

格式不正确，结构不清晰，汉语式英文思维太过明显，翻译的过程中常常不合英文写作要求。

应对的策略是多阅读范文，写作前列提纲，注意使用衔接词。

格式不正确常常出现在应用文中，有人会忘记写落款。这是我们在写作过程中特别需要注意的，否则格式错误就要相应的扣分。另外，有些文章结构不清晰，或者没有分段，或者段落之间的内容混乱。开头段就开始论述问题，第二段提出建议，结尾段又给出原因，逻辑混乱不清，抓不住重点。所以我们在写文章时一定要先打腹稿，明确行文结构和大概内容，这样在写作过程中才不至于不知道说什么，甚至瞎写一通。

总而言之，新大纲非常强调大家的英语写作技能，我们在平时的备考过程中一定要多进行英文文章的写作，养成良好的写作习惯，注意单词拼写、语法检查、逻辑结构，这样写出的文章才能过关。

请以“My Best Friend为题，写一篇不少于60个单词的作文。

My Best Friend

我最好的朋友

My best friend is one of my classmates. Her name is Mary. Every day, we go to school together and go back home together. We often help each other and learn from each other in study.

我最好的朋友是我的一个同班同学，她的名字叫玛丽。我们每天一起上学，一起回家。我们经常互相帮助，并向对方学习。

We have the same hobby-collecting stamps. She has many nice stamps. She is very proud of them. Sometimes she gives some of them to me. I think she is a very good girl. We will be good friends forever.

我们有着相同的爱好——集邮。她有很多漂亮的邮票，并为此十分自豪。有时，她会把其中的一些邮票给我。我认为她是个非常好的女孩。我们会成为永远的朋友。

点评：这是一篇记人的叙述文。先交代了My Best Friend是谁，接着通过事例交代了为什么“我们是最好的朋友”。最后阐述了主题。

节日的夜晚，一束束焰火凌空而起，有的仿佛天女散花，有的像孔雀开屏，五颜六色，光彩夺目，给节日增添了喜庆的色彩。那么焰火的色彩是怎么来的呢？

为了搞清这个问题，我拆开了几个没燃放的焰火和查阅了资料。原来焰火的原料主要是黑色火药，黑色火药在燃烧时，能放出大量的热和光；另外，原料里还掺入了各种发光剂，这些物质燃烧时，会呈现五颜六色。硝酸钠会发出黄光，硫酸铜会发出蓝光，铝粉、铝镁合金会发出白光，硝酸锶会发出红光……为了使焰火色彩更加艳丽，火药燃烧得更彻底，工人师傅在火药中还要掺入硝酸钾、镁粉等。它们受热后分解，能释放出大量的氧来助燃。

焰火点燃之后，会立即发生剧烈的化学反应，骤然间火药的体积猛胀1000多倍，并突然炸开，构成多种多样的形状，千姿百态，绚烂多彩。

Hi! Peter,

I’m glad to know you are having a good time in Chengdu.

TheSpring Festival is the most important festival in China. It is a custom to give lucky money to children. I get lucky money every year. I will put most of it in the bank, and spend the rest on some books. This year is no exception(也不例外) and I also got lucky money.With it, I bought some school things for several poor students in Ningxia，hoping the things can bring some happiness to them.

For you, I think it’s a good idea to buy a gift with the lucky money for your hostfamily before you leave China. You can also buy some Chinese gifts for your parents and friends in England. Or, just keep it as good memories.

I hope what I said can help you.

Yours,

中学生怎样写好说明文在国家教育部制定的《语文课程标准》中，写说明文是对中学生的要求。 说明文是用说明的表达方式来解说事物、阐明事理、给人以知识的文章。简单地说，说明文就是把你要写的对象介绍给读者，其标准就是介绍的是否清楚、明白、易懂。 在我们的日常生活中，说明与人的关系十分密切，你经常要向人们介绍事物或者某种道理。所以，说明并不是神秘的事情，在日常生活中人人都会。 对于写说明文来说，其题材领域十分宽广，大到宇宙小到一根铅笔都可以说明，都能写成说明文。比如，做饭、做菜、穿衣睡觉、治病防病、吃饭喝水，这些日常行为都可以写成说明文，再比如，春夏秋冬、风雨雷电、水、空气这些自然现象也可以写成说明文，钢笔、课桌、书籍、本子这些学习用品还可写说明文，城市、村庄、学校等等地点场所也可以写成说明文。与此同时，怎样写作文、怎样听课、怎样考虑这些做事情的道理也可以写成说明文，称为事理说明文。应该说，我正在写的这篇《说明文的特点及写作要求》就是一篇事理说明文。 说明文的特点在于说明、介绍。与记叙文不同，记叙文是记人叙事，所以说明文不以人物活动和故事情节为主，它是对事物的静态介绍。与议论文也不同，议论文是海阔天空地摆事实讲道理，有论点、论据、论证，而说明文中的事理说明文就是就此事的道理做静态介绍。 知识性、通俗性和条理性是说明文的三大特点。 知识性是说明文的本质特征。对一个事物缺乏知识，我们可以写成记叙文，但绝对写不成说明文。说明文正是要介绍该事物的知识，没有知识怎样说明呢。 通俗性也很重要，事物本身的结构、形态、历史及其科学知识是很复杂的。我们写说明文的目的就是要把这些复杂变简单，把深奥变通俗，所以写出来的文章，要使有点文化的人都能看懂，不要把明白人给绕糊涂了。 条理性是指说明文的行文结构。既包括整篇文章的结构，也包括一个段落的结构，还包括两句话之间的结构，都要有条理。要按部就班地去说明，有条有理地、清清楚楚地说出来。在结构上，说明文没有记叙文和议论文那么自由。 所以，在说明文的写作中，要普遍注意以下方面：一是要有该事物的知识，二是要抓住事物的特点进行说明，三是要科学地安排说明顺序，四是采用恰当的说明方法。
