Today was the first day of my new life. I looked at my new books and checked everything for the new school year. I was excited as well as worried.

今天是我新生活的第一天，我翻看我的新课本，检查了新学年的一切。我既激动又担心。

Entering new school, I was curious about everything, new classrooms, new teachers, new classmates etc. It would be a new start for each student. And what I was worried about is that I had no friends here. I wondered if no liked to play with me. Were the teachers strict with students?

进入新的学校，我对所有事情都很好奇，新的教室，新的老师，新的同学等等。这对每个学生来说都是一个新的开始。我所担心的是在这没有朋友。我想知道是不是没有人喜欢和我玩。老师对学生是不是很严厉?

I fell relaxed when the teacher asked me, What else could I help you, freshman?". I found that the teachers were kind and polite, and the classmates around me were friendly. While I was thinking about how to get on well with my classmates, my desk mate showed me his favorite Ipad4s. He wanted to play with me, but I didnt know how to play, so he taught me patiently, and we played happily.

当老师问我：“我能够帮你什么吗，新同学?”的时候，我一下子觉得放松了。我发现老师很善良很有礼貌，周围的同学也很友善。正当我想着怎样和同学相处的时候，我的同桌给我看他最爱的Ipad4s。他想和我一起玩，但是我不知道怎么玩，于是他就耐心的教我，然后我们就开心的玩起来。

Worries have gone, and happiness is coming.

忧虑已经消失了，幸福即将来临。

Asthe saying goes, “A friend in need is a friend indeed”. Friends play a veryessential role in our daily life. However, how to make goods friends is aproblem for most of us. As for me, I have three principles to choose friends.

正如谚语所说的那样，患难见真情。朋友在我们日常生活中扮演着非常重要的角色。然而，如何交到一个好朋友是我们大多数人都遇到过的问题。

In the first place, good friends should have their own principles. Weshould take into account the fact that people who insist on their principleshave high quality. Therefore, it is worth making friends with them.

首先，好朋友应该是有他们自己的处事原则。我们应该认识到这样一个事实，坚持自己原则的人一般都是具有高尚的品格。因此，这样的人值得我们去交朋友。

Then, I want to point out that good friends should be full of trust.This kind of person has a pure heart, so we can communicate with each other byheart.

然后，我想说的是，好的朋友应该是充满真诚的。这样的朋友有一颗赤子之心，我们能用心来彼此交流。

Finally, active friends are just like beautiful sunshine. They can lightup our blue mood, drive away the dark clouds and give us courage.

最后，拥有积极心态的朋友就像美丽的阳光。他们能够照亮我们忧郁的心情，驱走乌云，给我们鼓励。

Friends who have above three characteristics will be great wealth forus.

能交到有以上三个特征的朋友将会是我们巨大的财富。

Since I went to college, I feel so excited about the new chapter of my

life. I have imagined the campus life for so many years. Now I finally come to

this stage. I have much time after class, so I need to learn to deal with it.

After two years’ struggling, I find the right way to spend my time.

The first thing for every college student is to learn major knowledge. In

China, so many students think college time is used to play instead of study, so

they skip class. This is a big mistake. College is the stage for students to

master practical skills, which decides what kind of job they will work on. So I

study very hard from Monday to Friday. I don’t want to miss the important

knowledge.

The second thing for college students is to join the after-class

activities. Joining the activities can not only learn more skills, such as dance

and sports, but also can make friends. Campus is like a small society. Students

need to learn to make connections with other students, so that they can win more

chances. I learn a lot from my new friends and know how to communicate.

My college life is wonderful, I learn both knowledge and social skills.

巴金曾说过：“目标，是人类迈向成功的动力源泉。”没有目标的人生就犹如行尸走肉，空有一身躯壳，只有拥有了目标，才拥有了灵魂，最终走向成功。

匡复汉室，鞠躬尽瘁，死而后已，这是孔明先生的毕生目标;复兴中华，三民主义，这是国父孙中山的奋斗目标;消除歧视，人人平等，这是南非之父曼德拉先生的追求。没有目标的人生，就犹如在黑夜中行走，空洞，而又毫无意义。竖立一个值得你毕生为之风斗的目标，你的人生也会因此而精彩。

拥有目标，就不用再去选择是砍红松呢，还是砍杨树呢?拥有目标，你的人生也会因此意义非凡。

坚持目标是克服一切困难的信念。在通完世界第一的这条路上，丽娜遭遇了无数的困难。病魔一遍又一遍地袭击李娜的身体。世界冠军、奥运冠军、大满贯、二夺大满贯，李娜成功地证明了自己。即使李娜在最终倒在伤病前，依然只是世界第二，但那又怎样?坚持目标，是李娜克服伤病，走向成功的信念。如果没有这股信念，即使没有伤病，李娜也无法成功登顶。

坚持自己的目标，如果你要做工艺品，即使杨树再好，松树再差，你依然要坚定不移地砍红松。成功的路上布满挫折，只要坚定信念，必能走向成功。

实现目标，到达成功的彼岸。阿里巴巴的创始人马云，从一名笑笑的电商最终成为身价百亿的巨富凭的是是什么?凭的便是他拥有一个伟大的目标—创建中国最大的电子商务交易平台，然后为之奋斗，为之坚持。最终完成了目标，创造了难以想象的成交额。

实现目标，让光明驱走黑暗。成功的彼岸早已遍地鲜花。

成功往往只是简单的三部曲—拥有目标，坚定目标，实现目标。说是简单，可真正做到的却又寥寥无几。即使这样，我们也要驾着巨帆，在这黑夜中，向着目标的灯塔，坚定不移地前行，因为那成功必在那充满光明的地方。

One possible version:

In recent years, a series of food safety incidents, such as melamine-tainted milk, lean meat powder, the dyed steamed buns, etc, have appeared across our country. As is vividly shown in the picture, the young wife is cooking. She is asking her husband whether he has finished checking the vegetables, and her husband answers that he needs one more step. This cartoon vividly illustrates how worried ordinary people are about food safety situation in China.

Several reasons contribute to this phenomenon. Firstly, people are too concerned about making quick money and short-term success during this period of economic and social transition. Secondly, ineffective supervision is also to blame. Some food inspectors make profits from the fines of illegal companies and therefore are unwilling to shut them down.

I firmly believe that urgent measures must be taken to prevent similar cases from happening again. First of all, the authorities concerned should step up their efforts to ensure food safety and severely punish those who break the Food Safety Law. Meanwhile, we must strengthen education of social morality to make sure that companies shoulder more social responsibilities and take consumers’ interests and health into account. Only in these ways can we set up a sound food safety system.

As we all know, pollution is harmful to living beings. There are many different types of pollutions in this world. For instance, water pollution, air pollution, noise pollution and so on. Water pollution cause many kinds of disease that have negative effects on human beings, sometimes the diseases will take people’s life away. Dirty air will increase the rate of getting lung cancer. While the noise pollution will cause insomnia. People’s health condition will be damaged.

In my humble opinion, people should take measures to control the pollution. Recently, not only the government, but also individual has taken part in the action of protecting the environment. This is a good sign. Rivers are being cleaned, air is purified, and the people come to realize that the importance of protecting the environment.

However, this is not enough, the problems are still exist. Not all of them have been solved. Some factories are still pouring dirty water into the rivers or give off the toxic gas into the sky. We should know that protecting the environment needs everybody’s effort.

The 15-Day Celebration of Chinese New Year

The first day of the Lunar New Year is the welcoming of the gods of the heavens and earth.Many people abstain from meat on the first day of the new year because it is believed that this will ensure long and happy lives for them.

On the second day, the Chinese pray to their ancestors as well as to all the gods. They are extra kind to dogs and feed them well as it is believed that the second day is the birthday of all dogs.

The third and fourth days are for the sons-in-laws to pay respect to their parents-in-law.

The fifth day is called Po Woo. On that day people stay home to welcome the God of Wealth. No one visits families and friends on the fifth day because it will bring both parties bad luck.

On the sixth to the 10th day, the Chinese visit their relatives and friends freely. They also visit the temples to pray for good fortune and health.

The seventh day of the New Year is the day for farmers to display their produce. These farmers make a drink from seven types of vegetables to celebrate the occasion. The seventh day is also considered the birthday of human beings. Noodles are eaten to promote longevity and raw fish for success.

On the eighth day the Fujian people have another family reunion dinner, and at midnight they pray to Tian Gong, the God of Heaven.

The ninth day is to make offerings to the Jade Emperor.

The 10th through the 12th are days that friends and relatives should be invited for dinner. After so much rich food, on the 13th day you should have simple rice congee and mustard greens (choi sum) to cleanse the system.

The 14th day should be for preparations to celebrate the Lantern Festival which is to be held on the 15th night.

[高中英语作文：元宵佳节

It seems we are living in the conflict between modern and traditional cultures every day. Hearing the blaring of horns the moment you step out of your house, seeing the so called "pop" the moment you open your eyes, you cant help thinking, "Will the traditional culture be gradually lost?"

Many people believe so. They may put right in front of you all the evidences they can dig out. They may argue that people are rushing to restaurants instead of cooking at home, listening to pop music but not traditional, wearing in a way people couldnt imagine ten years ago. Modern people like the air of freedom, not to be restrained by traditions. They offer this long list, only trying to confirm that this world is full of fashion,competition and temptation and the traditional culture is fading

and will be lost at last.

Though we are now living in a world in which undeclared aggression, war, hypocrisy, chicanery, anarchy are part of our daily life. Though this is a skeptical age, and our faith has weakened, our confidence in some aspects of the traditional culture should and would never be lost.

Wouldnt you agree that our traditional culture is always credited with modesty, politeness and respectfulness, which have always been treasured for more than five thousand years?Even in this modern world, people still admire those with good manners, those who are polite to others or respectful to old people.

Wouldnt you agree that our Chinese traditional music is beautiful and artistic and our Chinese tea culture is always an appealing treasure to people around the world?

So there may just be some changes in our lifestyle or our attitudes towards life, but little change occurs to some fundamental aspects of our traditional culture that people still treasure in heart.

When I was a child, I raised a pet, named Lucky.Actually he is a cat.His fur is soft with yellow and white color.Lucky is a good boy.He always behaves well.I remember when my uncle took him back to my home at first, I was afraid of him.But soon I found him is very interesting.I started to play with him.As time goes, we like each other very much.And then my uncle gave him to me.I was so happy.Now he always lies beside me quietly, when I’m doing my homework.As winter comes, he will sleep with me.sometimes he will dance for me, which is very funny and sometimes his hands are wet would leave many “plum flower” on the ground.He is so lovely.

在我还是个孩子的时候，就养了一只叫做幸运的宠物。其实他是一只猫。他的毛很柔软，是黄色和白色。幸运的是一个好男孩。他总是很听话。我记得当我叔叔带他来到我家的时候，我很怕他。但不久后，我发现他很有趣。我开始和他玩。随着时间的推移，我们都互相非常喜欢对方。之后我叔叔就把他送给了我。我是如此的高兴。现在他总是在我做家庭作业的时候悄悄地躺在我的身边。冬天来了，他会跟我一起睡。有时他会为我跳舞，那是非常有趣的，有时他的爪子湿了就会在地面上留下许多“梅花”。他很可爱。

We also went to the Palace Museum. The Palace Museum has 9999 palaces. It has a very long history. I bought a lot of souvenirs of the Palace Museum. What nice palaces these are! I visited the Palace Museum and felt excited. If you want to know more about the Palace Museum, you can go to Beijing and have a look.

如果说童年是太阳初升的时刻——因为谈的纯洁与明净;如果说暮年是傍晚的黄昏——因为它是漫漫人生道路的尽头。那么青春呢?

青春是什么?

青春是破土而出的小草，极渴望阳光的温暖，茁壮成长;青春是嬉戏玩耍的鲤鱼，渴望跃龙门的壮志;青春是勇敢的海燕，渴望风暴的卷席。青春是我们朝气蓬勃，奋力向前的精神象征，像钟表的十点九分，代表着胜利与向上。

青春之路漫长与艰辛;青春之路任雨打风吹，那么索性，以劲风为号角，扯缆绳做琴弦，拿清声当作伴奏，狂浪里，我们放歌，让我们呼喊：“让暴风雨来得更猛烈些吧。”

当我们在青春之路遭遇坎坎坷坷之时，我们为何不去想想那海洋，随时间的流动，它时而平静如静，时而浪花如溅，时而巨浪冲天……人生也如此。

但请相信风雨过后有彩虹，只有经历风雨的洗礼，生命才会更有价值，青春才会更意义。你是否也曾发现青春也经历过痛苦、彷徨之后，而更加精彩。

当然，我们的青春也有些无奈。教室——食堂——寝室，三点一线，春秋不变。名次的压迫，功课的折磨，分数的蹂躏，我们只有逆来顺受，苦中作乐，只因分数是我们的生命线。

但我们不必在乎，若是因此而纵然伤感，不如一笑而过，因为我们的青春在乎的是快乐度过每一天，我们应勇敢面对，抬起头来，就会发现，分数的阴霾不过是短暂的影子。

everything lives with opposite forces。 the same can be said about modern technology， such asInternet。

at first glance internet offers us excitement and a worl of promise。 frankly speaking， people who have some ideas of it can not deny the merits born with the system。 for instance，it can improve proficiency in scientific research， for by means of it scientists and researchers can get a global look at the latest development in the field concerned and accordingly they need spend no time doing what has already been done。 in view of personal communication， the most convenient means could be peculiar to internet， too。

while people speak highly of internet， its drawbacks shouldnt be neglected。 sometimes， alittle fatal breakdown of the system， or a disastrous error could bring us an enormous amount of damage and loss。 meanwhile， with lnternets replacement of hooks or the written work as the main source of information， humans writing abilities are weakened and relations between people are desalinated。

however， every country on this planet should work hard to develop the system to serve us more efficiently and comfortably， because in the net all countries are interrelated。

The summer holiday is coming. Our class have had a discussion about what to do during the holiday. Some are in favor of staying at home. They think its both convenient and comfortable. Whats more, they can save money for other purposes. But they will lose the chance of getting to know the outside world.

However, others prefer to go out for traveling since it can increase their knowledge and broaden their horizons. But they will spend more money and meet some difficulties while traveling.

In my opinion, it would be much better to stay at home, for I can do what I like, such as reading books, watching TV, and helping my parents with the housework.

大自然的奥妙无穷无尽，给了人类无限创作的可能。在这一个个妙趣横生的问号中，我探索到了属于蜻蜓的小秘密。

“小荷才露尖尖角，早有蜻蜓立上头”。是不是说蜻蜓对荷花情有独钟呢?好奇心促使我去观察，去探索。

春光明媚的周日，我来到了日湖公园。那里有一方池塘，满池绿油油的荷叶，像千万把绿色的小油伞。那明亮的露珠，在荷叶上滚来滚去，春风一吹，荷叶犹如亭亭玉立的女孩羞怯的挤来挤去，而那晶莹剔透的小露珠全倾倒在池塘中，荡漾开一圈又一圈的小涟漪。春天的池塘有着别样的迷人风景。

哎呀!差点忘了此行的目的，赶紧的找个隐蔽的地方躲起来，一动不动，屏息凝视，嗯，我是一尊雕塑!

瞧，一只体态轻盈的蜻蜓，缓缓地“降落”在荷叶上。圆圆的脑袋上嵌着一对突出的浅绿色大眼睛，两对透明的翅膀轻轻地扇动着，它的尾尖轻触水面。快看!什么东西落了下来?博学的妈妈告诉我这是蜻蜓在产卵。

我恍然大悟，原来蜻蜓喜欢在水面上飞行，实则是在繁衍它的后代。想必这也是成语蜻蜓点水的由来。

忽然，一片阴影挡住了我的视线，我抬头一看，天空乌云密布，倾盆大雨仿佛随时都会倒下来，得赶紧去避避雨。咦，刚才还在高空的蜻蜓怎么飞得越来越低了，不会是受伤了吧?带着困惑，恋恋不舍地离开了这方池塘。

回到家，我迫不及待地在网上搜集了一些有关蜻蜓的资料：终于明白，蜻蜓低飞不是因为受伤，而是由于它的翅膀，在雨天感受到了湿气;再则蜻蜓捕捉的害虫在雨天也飞得很低，蜻蜓不得不一路追随它们。创作精神可佳的人类根据蜻蜓的飞行原理发明了直升机。

大自然中，还有许许多多的奥妙在未来等待我们去探索，去研究

Many traditional arts are losing nowadays, because some of them have been replaced by the new machines and the scientific products.

I feel so sorry about the losing arts, in my opinion, they are so classic and their charm will never fade away.

Take my grandma for example. She is good at paper-cut which was inherited from her mother.

But when comes to my mother’s generation, paper-cut seems to be kicked out, there are less people need it, so my mother doesn’t learn this skill. The paper-cut art is losing in my family. When I found my grandma had this skill, I was so surprised and curious about it. I asked my grandma to teach me this skill. During the process, I found this art was so great, I was attracted by it. Some traditional arts like paper-cup should be kept.

如今很多传统艺术正在消失,因为一些传统已经被新的机器和科学的产品所替代。对于正在消失的艺术，我感到抱歉,在我看来,他们是如此经典和有魅力,将永远不会消失。以我奶奶为例。

她擅长剪纸，继承了她母亲。

但是当到我母亲这一代,剪纸似乎被淘汰了,越来越少的人需要它,所以我的母亲不学习这个技能。

剪纸艺术在我家中逐渐失去。当我发现我奶奶有这个技能的时候,我是如此的惊讶和好奇。我叫奶奶教我这个技能。在这个过程中,我发现这门艺术是如此之大,我被它吸引住了。一些传统艺术像剪纸应该被保持。

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.
