My Opinion on Cheating in Examinations 我对考试作弊的看法

It is known to us all that some students cheat in examinations at school.

As students, we often take examinations at school, but sometimes we have too many examinations which are too difficult for us. On the other hand, some of us are lazy and dont work hard at their lessons. So when taking examinations, they sometimes cheat in order to get better results to please their parents and teachers.

In my opinion, it is wrong to cheat in examinations because it breaks the rules of schools. We students should be honest and try to get good results by studying hard instead of cheating in examinations. Whats more, we should improve our study methods and get well prepared for examinations.

Headmaster：

Hello，

My name is LiHong. I heard of our school will hold a activity about

welcoming exchange students from Canada. I want to let one exchange student come

to my home.

I want to know the culture about Canada. I think they are very happy to

tell me their culture. And I can introduce our culture to them. My parents want

to talk with a person who comes from Canada. It’s a good chance for them. So I

hope I can invite an exchange student to come to my home.

Maybe you will ask me if I have ability to talk with them. I can speak

English very well. And my family is rich， so I can make them fell

comfortable.

I can make school be proud of me!

The way for me to relax is various. First, I will listen to the music. Hearing the music can smooth my heart, it helps calm down, so I will get out of the annoyance. Second, I like to do some sports, such as jogging, basketball and tennis. Doing these sports also helps me let out my bad emotion and I become energetic again.

自从我上高中，我就感受到了很大的压力。高中是我生命中很重要的阶段，因为如果我学得好，就能进入到理想的大学，有一个光明的前途。因此我想要做到最好，我不想要落后。问题就是我不可能一直都是尖子生，有时候我考试也会失败。在那个时候，我需要调整自己，并且放松。我放松的方法是多样的。第一，我会听音乐。听音乐能让我的心顺畅，也帮助我冷静下来，这样我就能把烦恼抛去。第二，我喜欢做一些运动，比如慢跑，篮球和网球。做这些运动能帮助我释放不好的情绪，再次变得活力四射。

The majority Han Chinese have long followed the tradition of eating laba rice porridge on the eighth day of the twelfth lunar month. The date usually falls in min-January and is a traditional Chinese festival.

Legend about the origin of this festivity abounds One maintains that over 3,000 years ago sacrificial rites were held in the twelfth lunar month when people offered up their prey to the gods of heaven and earth. The Chinese characters for the hunt and the twelfth month were interchangeable then, and ever since la has been used to refer to both. Since the festival was held on the eighth day of the last month, people later appended the number eighth , giving us the current laba.

Buddhism was well accepted in the areas inhabited Han Chinese, who believed that Sakyamuni, the first Buddha and founder of the religion, attained enlightenment on 12/8. Sutras were chanted in the temples and rice porridge with beans, nuts and dried fruit was prepared for the Buddha. With time the custom extended, especially in rural areas where peasants would pray for a plentiful harvest in this way.

There is, however, another touching story. When Sakyamuni was on his way into the high mountains in his quest for understanding and enlightenment, he grew tired and hungry. Exhausted from days of walking, he passed into unconsciousness by a river in India. A shepherdess found him there and fed him her lunch.

Yes ah! Would it not everyone should be protected?

As is known to all， food is a priority for the mon people.Recently，

however， reports about food problems have often been seen in the newspapers，

showing that people have always been concerned about what they eat every day.

The reason for this problem is that some of the food producers are too fond of

making money， leading to the result that they use whatever will make the food

look good or taste better without considering the bad consequences。 This is not

normal because people just cannot live without eating anything.

So we should take all the measures necessary to forbid the food producers

to make food that is not safe enough. Laws should be strengthened and the

government should have more control over these producers。 Only when people are

no longer worried about whether their food is safe or not can they enjoy a

better life.

总是很羡慕电视机里军人们站如松、坐如钟的飒爽英姿，以及那“流血流汗不流泪”的坚毅精神，想着自己是不是也能这样坚持呢？这不，机会终于来了。

一大早，我们学校七年级新生都换上了军训时穿的迷彩服，远远望去，就如同一幅巨大的油画。我当然也在其中，虽然表面看来，我十分淡定，但是只有我自己知道内心是如此的汹涌澎湃。我好像看到了一只独木船正在海面静静地向前航行，忽然，刮起了大风，巨大的海浪一个接着一个，如同成群的野兽，向独木船奔去。

想起哥哥说过的话，“你要小心点，我们军训的时候，教官十分严厉，动作稍微做得不到位，就要被罚！”想得正出神，老师便来带我们下楼参加典礼。我可以明显感觉到我的心脏里住着一头小鹿，它胡乱地撞着我的胸口，就差要跳出来了！

带领我们的是一位浓眉大眼的教官，眉宇间夹着一个深深的“川”字。他一脸严肃，在训练的时候，我没看到他脸上有过一丝笑容，眼睛睁得大大的，好似两个铜铃，怪可怕的。教官一本正经的模样使我胆怯起来，同时打起了十二万分的精神。

教官在教我们每一个动作前都会做一遍给我们看，那炯炯有神的眼睛，那干脆利落的动作，那挺拔如松的站姿，我能想到的只有一个字，那就是——帅！

刚开始我们做的动作一点儿都不整齐，经过教官一次又一次的纠正，我们一次又一次的努力，总算能像教官一样——站如杨树，蹲如雕塑。一个个挺拔的身影，洪亮的口号声久久回荡在篮球场上，这分明就是一个个军人在接受着人民的检阅啊！

一天的训练就在这热烈的气氛中结束了，每个人的脸上虽然都显得有些疲倦，但从一双双明亮的眼睛中，分明可以看出那巨大的成就感——那种无法言语的感觉！

As is shown in the picture, two men had a big dinner in a restaurant, but much of the food was left and some was even untouched at all. When the waitress asked them to pack the remaining food, they felt very surprised, thinking that it was unbelievable for them to do things like that with too much money in their pocket.

It is a pity that many people act like the two men in the picture. In my view, we should pack the leftovers when we have meals outside. As we all know, saving is a fine tradition for our Chinese people and therefore we shouldn’t waste a bit food. Also, there is not enough food in the world and there are many people starving. In addition, we students should form the habit of saving food and give away some to the people in need. Finally, we have the responsibility to help people around us realize the importance of saving.

Only in this way can we build up an economized society and live a happy and healthy life.

如图片所示,两个男人在一家餐馆吃了丰盛的晚饭,但是剩下的食物和一些甚至没有。当服务员问他们打包剩下的食物,他们感到很惊讶,以为他们是不可思议的事情,用太多的钱在他们的口袋里。

遗憾的是,很多人就像照片中的两人。在我看来,我们应该把剩饭剩菜,当我们在外面吃饭。我们都知道,节约是我们中国人的优良传统,因此我们不应该浪费食物。同样,世界上没有足够的食物,有很多人挨饿。此外,我们学生应养成节约粮食的习惯和放弃一些有需要的人。最后,我们有责任帮助我们周围的人们意识到节约的重要性。

只有用这种方法我们才能建立一个节约型社会,过幸福健康的生活。

A lunar New Year, no doubt, is sound, taste and township.

A New Years eve firecrackers. Melody in the New Year, fireworks is low and grand drums, heavy yet explosive, accompanied by a large umbrella of scattering flowers, jinlong fall and arc of the rainbow, here every corner of the flower, a pair of, a group of cheng fang, a piece, a world, in a sudden the incomparable luster. And on the square table, and celebrate the applause, light spirit is ringing, can not help but think of "harps friend" -- it is natural to performance, the smile of gentle feeling let everyone around without his joy. Then a sound clear gong, it is in the middle of the night the cheer of the New Year, is not so short but lingering sound waves, times, stretches, like a stream, seeped into next year. In the end, a string of bells sound, it so mysterious, as if the passage of time, is at the end of the sea and the nien beast roar.

Through every form, and to have bouts of aroma. Like bacon that hard sweet, like the mutton soup hot sweet, like the natural aroma of coarse grains like steamed bread fresh incense, sweet like a sausage chewy, like dumplings a pack of sweet juice, like nuts, crisp sweet, like good old 994 stuffed sweet ChunChun... The fragrance, as they themselves. A wisp of fragrance, flavor, a dish, a table, a handful of happiness. I like dumplings, white white fat, quietly lying on the soup. It successfully, that sweet thick sesame paste, now a love heart.

JianJu the most popular cartoon "bears in the New Years day" in a situation: even if a lumberjack, also know that mothers dumplings, dads wine, are looking forward to the calendar page, end the arrival of the New Years eve. Whether its cold rime, shaking winter bamboo shoot, a speeding train, shimmering bright lights... Township, there is only one, let the wanderer to gallop tirelessly.

But you have such a scene: in the mobile phone clicking, hands of quick-frozen dumplings immodesty slide to the ground, fell to pieces, like a boom ray reminds you, want to travel to Hong Kong this year Spring Festival. So, the sound? Taste? Township?

一个春节，无疑便在于声、味、乡。

爆竹声中一岁除。过年的曲谱中，烟花是低沉而隆重的大鼓，重重的一声声爆响，伴随着大伞的散花、金龙的出落和弧形的彩虹，在这儿的每个角落一朵、一双、一群、一片、一世界地盛放，在瞬间迸发出无与伦比的光彩。八仙桌上的谈笑，与庆祝的掌声，轻灵清脆，不禁联想到“琴瑟友之”——它自然是尽情的琴声了，笑的柔和让周围的每个人都情不自己地欢欣起来。然后是一声清亮的锣响，它就是午夜时分新年的那一阵欢呼，虽短，但余音袅袅，不绝如缕，一直绵延着，就如一条溪，汩汩地流向明年。最终，有一串编钟声，它那么神秘，好像是时间的流逝，是沧海尽头年兽的咆哮。

走过每一个门洞，都有一阵阵的香飘来。像是腊肉那硬硬的香，像是羊肉汤那热乎乎的香，像是粗粮天然的香，像是馒头新鲜出炉的香，像是香肠有嚼劲的香，像是饺子一包汁的香，像是坚果干脆的香，像是陈年佳994酿醇醇的香……这香味，就如它们本身。一缕香，一丝味，一盘菜，一桌人，一捧幸福。我最喜欢汤圆，白白胖胖，安静地躺在汤里。它圆满的外表下，那甜稠的芝麻馅，宛然一颗爱心。

简举最红的动画片《熊出没之过年》中的一情景：就算一个伐木工，也懂得，妈妈的饺子，爸爸的酒，都是期待着日历的那一页，岁末除夕的到来。不管是冰冷的雾淞，晃动的冬笋，飞驰的火车，灿亮的灯光……乡，只有一个，让游子不倦地飞奔。

但是你的身边有这样的场面吗：在手机的点击声中，手里的速冻汤圆不慎滑落在地，跌得粉碎，像轰雷般提醒了你，今年春节要去香港旅游。如是这样，声呢?味呢?乡呢?

Since I went to middle school, I grew up very fast. On the one hand, I live

in school from Monday to Friday, so I need to learn to get along with roommates.

We share the cleaning work to make sure a good environment. It is everybodys

duty to sweep the floor on turn. On the other hand, I need to solve the problems

from life by myself. Without parents by my side all the time, I learn to face

troubles and figure out all the ways to solve them. I become much independent

and stronger. Now I can deal with my stuff alone.

Many animals are in danger of dying out. As is shown in the chart, we can

see the number of animal species decreases faster and faster and this trend will

continue. From 1980 to 2010, at least 1 million animal species have disappeared.

Worse still, more and more wild animals are in great danger. It is not a piece

of sensational news; it is a fact, a harsh reality. Unfortunately, we may not

see these animals in the near future.

From the second picture, we can find some reasons. Why is the number of

animal species declining year by year? Apparently animals have become victims of

fashion industry. Animal skin has been used to make fashionable clothes and

these clothes sell at a high price. So some greedy people begin to kill animals

in a large quantity. This irresponsible behavior not only breaks the balance of

nature but also endangers the living environment of human beings.

As far as I am concerned, something must be done to stop this illegal

action. We believe "no buying, no killing". First, we must make concerning laws

to protect these animals in danger. Second, we must take some measures to

protect animals effectively. Animals are our friends and part of our

environment. Third, we should raise peoples awareness to protect animals and

our environment. In this way, we can build a harmonious society and ensure a

sustainable development.

Have a healthy body it is very important for us.How to have a healthy body?It is necessary to keep a balanced diet if you want to have a healthy body.Youd better eat enough vegatables which contain rich vitamin, proper meat is needed,too.

I like my school life very much,it is very interesting.I usually reach school at half past seven.Then we do morning exercises at eight oclock.We have eight lessons every day.

我非常喜欢我的学校生活，这是非常有趣的。我通常点半到达学校七。然后我们做早操八点clock.we每天有八节课。

Despite the efforts made by the government， many college graduates failed to get a good job this year and felt depressed and ashamed. Whats worse, some of them committed suicide, just like Miss Liu in this report.

I came across many setbacks in my study and life. For example, I failed in my math final exam when I was in Senior One. Knowing the result, I cried hard. I analyzed the situation and studied harder. With all my efforts and the help of others, I finally became good at math and passed many exams.

In my opinion, setbacks are harsh teachers, but the lessons we learn from them can be invaluable. When setbacks happen， we should be brave and stay optimistic. It is a good way to relieve the pain to turn to our trusted ones for comfort, see a funny movie, listen to music, or visit a beautiful place. After we cool down, maybe we can gain something out of this painful experience.

尽管政府作出了努力，许多大学毕业生今年没有找到一份好工作，感到沮丧和羞愧。更糟糕的是，其中一些人自杀了，就像刘小姐在这份报告中。

我在学习和生活中遇到了许多挫折。例如，我在数学期末考试时，我是在高级一。知道结果，我哭得很厉害。我分析了形势并努力学习。在我的努力和别人的帮助下，我终于考上了数学，通过了许多考试。

在我看来，挫折是严厉的老师，但我们从他们身上学到的教训是无价的。当挫折发生时，我们应该勇敢保持乐观。这是一个很好的方法来减轻疼痛转向我们值得信赖的人安慰，看一个有趣的电影，听音乐，或访问一个美丽的地方。我们冷静下来后，也许我们可以从这痛苦的经历中获得一些东西。

Topic one：Environment Protection(环境保护)

Water Pollution

With the development of industry, water pollution is becoming more serious now. The polluted water not only kills fish, it is also harmful to our health. Many people get sick because they drink the polluted water. In some rivers the water is so dirty that they can even kill plants.

We should fight against the pollution. We should stop using harmful things. I wish it is not a dream that in the near future we can have clean rivers again.

Environment Protection

Nowadays, peoples life has changed a lot with the development of modern technology and economy, which has put lots of negative effects on the environment.

Why this? Because, firstly, some factories are pouring wastes into rivers, lakes, seas and so forth; secondly, because of human activities, a great number of plants and animals are losing their lives; thirdly, using modern machines and chemicals is bad for the environment. Besides these, there are a lot of human activities which have done or are doing harm to our surroundings.

For this, I think, first, our government should make drastic measures to regulate human activities; second, we human beings should take pains-taking work to stop ourselves destroying the environment and try our best to protect our living space more.

Forest Pretention保护森林

Our country has a large area of forest. However, not until recently did the government begin to realize the importance of protecting the forest. As we may know from various sources, the government recently adopted a policy called "restore the farmland to the forest"(退耕还林).This has brought much hope to the forest of our country as well as the sustainable development of our country.

Pollution: a Social Problem

When we read newspapers, we often come across the word pollution. This word was not familiar to the people some decades ago. But now, it is a serious threat to usbecause. it means the poisoning of the air, seas, rivers and lands, which would do harm to our health.

There are many factories that bring pollution to us. We can not have fresh air in the morning. This is mainly because of the poisonous smoke coming from factories, especially chemical ones. In rivers, seas and oceans, there are industrial wastes. Some factories just throw their wastes into seas or let them flow into rivers. When people drink the water from such rivers, they get poisoned. Besides, there is rubbish from ships and when sometimes an accident occurs in an ocean, oil flows out from tankers.

On land, the accumulation of rubbish in the streets may dirty the city and ruin our health. This is mainly due to the improper disposal of rubbish by people.

If we do mot fight against pollution, surely one day all of us will be killed. Some people like to put the blame on the industrial revolutions. On the contrary, the pollution problem will be solved only with the help of modem science and technology.

The dream blooming flower Everyone has a dream, a beautiful dream. Different environment, different life background, experience of things different, everyone’s dream is also different. Some people want to become national leaders, some people want to be a scientist, and some people want to become a businessman. The dream I just want to be an ordinary person. Do the people useful things in ordinary post. For example, when a teacher, to impart knowledge to the next generation; when a doctor, save dead trauma; when a gardener, contribute to the greening of the environment. The dream is beautiful, but to achieve the dream, no words can, in the dreams of the road, will encounter difficulties, setbacks, resistance, if did not have the courage, will, you will be very difficult to realize his dreams. The dream cannot do without knowledge, so I think the first step to realize my dream is to accumulate knowledge, we now need to do is to Study hard, overcome the difficulties in learning, grasp more knowledge, to lay the foundation for the realization of dreams. Let us brave to face life

Today is the annual traditional festival in China, "Spring Festival". The morning sun was still in bed, I was like the sound of firecrackers to wake up.

The Spring Festival is the most important festival in China. On this day, every family has to eat dumplings, set off firecrackers, put up couplets and hang lanterns, which is the happiest and happiest day of the year.

2007年5月31日是第20个“世界无烟日(WorldNo-TobaccoDay)”，世界卫生组织再次告诫人们“烟草吞噬生命”，不论是何种香烟，对人体同样有害。

烟草在全球已盛行了200多年，但直到20世纪，人类才开始认识到烟草对人类的危害。自20世纪50年代以来，全球范围内已有大量流行病学研究证实，吸烟是导致肺癌的首要危险因素。为了引起国际社会对烟草危害人类健康的重视，世界卫生组织1987年11月建议将每年的4月7日定为“世界无烟日”，并于1988年开始执行。自1989年起，世界无烟日改为每年的5月31日。

香烟中含有1400多种成分。吸烟时产生烟雾里有40多种致癌物质，还有十多种会促进癌发展的物质，其中对人体危害最大的是尼古丁、一氧化碳和多种其它金属化合物。一支烟所含的尼古丁就足以杀死一只小白鼠。香烟烟雾中大量的一氧化碳同血红蛋白的结合能力比氧大240—300倍，严重地削弱了红细胞的携氧能力，因此，吸烟使血液凝结加快，容易引起心肌梗塞、中风、心肌缺氧等心血管疾病。更为严重的是，吸烟者还严重妨碍他人健康。研究结果表明，吸烟者吸烟时对旁人的危害比对他自己还大。

有关医学研究表明，吸烟是心脑血管疾病、癌症、慢性阻塞性肺病等多种疾患的行为危害因素，吸烟已成为继高血压之后的第二号全球杀手。据统计，全球每年有500万人死于与吸烟有关的疾病，如果不加控制，这一数字到2020年时将达到1000万。有资料表明，长期吸烟者的肺癌发病率比不吸烟者高10倍至20倍，喉癌发病率高6至10倍，冠心病发病率高2至3倍，循环系统发病率高3倍，气管类发病率高2至8倍。被动吸烟的危害更大，每天平均1小时的被动吸烟就足以破坏动脉血管。一些与吸烟者共同生活的女性，患肺癌的几率比常人多出6倍。目前全球有13亿烟民，其中9亿人在发展中国家。吸烟者的人数，特别是青少年烟民的数量越来越多。中国约有3。5亿吸烟者。2002年，中国男性吸烟率为66%，女性吸烟率为3。08%。中国烟民正趋于低龄化，青少年吸烟人数高达5000万。调查显示：全球少年烟民人数增多

虽然烟草业一直称这个行业带来的就业及税收对世界经济有很大贡献，但根据世界卫生组织提供的数据，烟草业对经济的贡献远远不够抵消它对家庭开支、公共健康、环境及国民经济等造成的损失。因此，世界卫生组织将烟草流行作为全球最严重的公共卫生问题列入重点控制领域。2003年5月，在日内瓦举行的世界卫生大会上，世界卫生组织192个成员国一致通过了第一个限制烟草的全球性条约——《烟草控制框架公约》，为在全球控制烟草危害，共同维护人类健康提供了法律框架。

控制烟草危害是一个具有长期性、艰巨性和复杂性的公共卫生问题，也是一项政策性强的社会与经济问题。因此，世界卫生组织不仅告诫人们“烟草吞噬生命”，还要求各国政府对烟草生产行业制定严格的章程，并帮助人们了解吸烟危害健康的准确信息。
