Lets take actions as soon as possible! Lets protect the earth, and live a better environment.

Traditional Chinese culture is beginning to capture the attention of the world. This is true even as popular culture that has traditionally been considered Western begins to spread throughout China. Kung Fu, especially, has had a great impact on the millions of people who first learned about China through it. From that, they may come to China and learn about other aspects of this culture, such as traditional operas like the Beijing and Sichuan ones. Asian nations have long known about the greatness of ancient Chinese culture. Their own cultures are a mix of native ones and those Chinese characteristics. Korea and Japan long ago adopted ideas such as Confucianism is something that continues today even as it is challenged by Pop Culture. This strength comes from the ideas given in the Four Books of Confucianism (The Great Learning, The Doctrine of the Mean, The Analects of Confucius, and The Book of Mencius). These books built upon the ideas of an even more ancient period codified in the Five Classics. From them, the West learns such things as Fengshui and other concepts that are uniquely Chinese. China has taken steps to further this spread of its culture by establishing Chinese Cultural Centers in such places as the United States and Europe.

In the Warring States Period, a man in the state of Chu was offering a sacrifice(祭品) to his ancestors. After the ceremony, the man gave a beaker of wine to his servants.

The servants thought that there was not enought wine for all of them, and decided to each draw a picture of snake; the one who finished the picture first would get the wine.

One of them drew very rapidly. Seeing that the others were still busy drawing, he added feet to the snake.

At this moment, another man finished, snatched the beaker(烧杯，大口杯) and drank the wine, saying,"A snake doesnt have feet. How can you add feet to a snake?"

This idiom refers to ruining a venture by doing unnecessary and surplus things.

我想二十年以后当一名医生，帮助人们。即使当不了医生，我也想当一名宇航员去太空探险。如果能当一名医生就要做一位有名的好医生。做医生有很多好处，比如能帮自己治病。做一名宇航员也有好处，比如能看一看太空是怎样的，能帮助人类证明世界上有没有外星人。但是要做这两份工作是不容易的，还很危险的，比如做医生有可能感染传染病，做宇航员火箭发射和降落时有可能会爆炸。所以做这两份工作都是不容易的。

环卫工人是我们城市的舒适环境的创造者，他们让整个城市变得干净和美丽。他们应该得到我们的尊敬。下面，小编整理了几篇关于环卫工人的英语作文，以供大家参考。

关于环卫工人的英文作文一

Each time I feel very emotional after reading the news about bad or unfair treatment towards city hygiene workers. On one hand, they have to suffer the poor working environment; on the other hand, they do not earn the respect from the society or public. It is a very sad fact in China, which is a wake-up call for us to face the situation in good manner. In my opinion, the education background differences outweigh other factors. People who are not well educated do not see the hardwork and uneasy life of those city beauty workers. All they care is their own feelings and interest. Moreover, if we do not appreciate or cherish others devotion to the city, the city as a mirror will reflect its bad side towards ourselves. Therefore, the public need to learn to respect and behave properly such as not throw about the garbage. In addition, the government should also make its efforts to improve the treatment of those sanitation workers as well as set up a good example in the public.

There is nothing wrong about a childish girls idea, and she thought that job could provide the most freedom. But this reflect the obvious discrimination. However, there is a dustman in my department.

It is known to all that today the environment has been badly polluted.

Though many action have been taken to protect our environment, it still has a

long way to go. Two years ago, I went to middle school, and the first moment I

saw the environment, I found that trees were very small, and many workers were

busy planting trees. Now, when I looked around our school, the trees were taller

than people and they grew so fast. People always talk about planting trees but

less of them can take action. If they plant trees immediately, then there would

be more green scenery. Protecting the environment is not just words. We should

take action right now.

Tolerance is not only a kind of accomplishment,more than a kind of virtue.To be tolerant does not mean being so timid,instead of it,it means magnanimous by keeping an open mind.

To be tolerant should own the characters of being strict to yourself and treating others with a heart full of mercy.Easily forgiving yourself is not toleraance and its weakness instead of it.It also in terms of people to treat others with a heart full of mercy.Its sappiness to tolerate the people who dont treasure the tolerance.Its appeasement to tolerate the people who are not worth tolerating.And its indulgence to tolerate the unforgivable people.Therefore,the tolerance itself is also a a branch of knowledge.

How wide the world is,but there exists something wider than it----peoples heart.Lets learn to own the tolerance.

It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife. However little known the feelings or views of such a man may be on his first entering a neighbourhood, this truth is so well fixed in the minds of the surrounding families, that he is considered as the rightful property of some one or other of their daughters.

凡是有钱的单身汉，总想娶位太太，这已经成了一条举世公认的真理。这样的单身汉，每逢新搬到一个地方，四邻八舍虽然完全不了解他的性情如何，见解如何，可是，既然这样的一条真理早已在人们心目中根深蒂固，因此人们总是把他看作自己某一个女儿理所应得的一笔财产。

"My dear Mr. Bennet," said his lady to him one day, "have you heard that Netherfield Park is let at last?"

有一天班纳特太太对她的丈夫说：“我的好老爷，尼日斐花园终于租出去了，你听说过没有?”

Mr. Bennet replied that he had not.

班纳特先生回答道，他没有听说过。

"But it is," returned she; "for Mrs. Long has just been here, and she told me all about it."

“的确租出去了，”她说，“朗格太太刚刚上这儿来过，她把这件事的底细，一五一十地告诉了我。”

Mr. Bennet made no answer.

班纳特先生没有理睬她。

"Do not you want to know who has taken it?" cried his wife impatiently.

“你难道不想知道是谁租去的吗?”太太不耐烦地嚷起来了。

"You want to tell me, and I have no objection to hearing it."

“既是你要说给我听，我听听也无妨。”

This was invitation enough.

这句话足够鼓励她讲下去了。

"Why, my dear, you must know, Mrs. Long says that Netherfield is taken by a young man of large fortune from the north of England; that he came down on Monday in a chaise and four to see the place, and was so much delighted with it that he agreed with Mr. Morris immediately; that he is to take possession before Michaelmas, and some of his servants are to be in the house by the end of next week."

“哦!亲爱的，你得知道，郎格太太说，租尼日斐花园的是个阔少爷，他是英格兰北部的人;听说他星期一那天，乘着一辆驷马大轿车来看房子，看得非常中意，当场就和莫理斯先生谈妥了;他要在‘米迦勒节’以前搬进来，打算下个周未先叫几个佣人来住。”

"What is his name?"

“这个人叫什么名字?”

"Bingley."

“彬格莱。”

"Is he married or single?"

“有太太的呢，还是单身汉?”

"Oh! single, my dear, to be sure! A single man of large fortune; four or five thousand a year. What a fine thing for our girls!"

“噢!是个单身汉，亲爱的，确确实实是个单身汉!一个有钱的单身汉;每年有四五千磅的收入。真是女儿们的福气!”

"How so? how can it affect them?"

“这怎么说?关女儿女儿们什么事?”

"My dear Mr. Bennet," replied his wife, "how can you be so tiresome! You must know that I am thinking of his marrying one of them."

“我的好老爷，”太太回答道，“你怎么这样叫人讨厌!告诉你吧，我正在盘算，他要是挑中我们一个女儿做老婆，可多好!”

"Is that his design in settling here?"

“他住到这儿来，就是为了这个打算吗?”

"Design! nonsense, how can you talk so! But it is very likely that he may fall in love with one of them, and therefore you must visit him as soon as he comes."

“打算!胡扯，这是哪儿的话!不过，他倒作兴看中我们的某一个女儿呢。他一搬来，你就得去拜访拜访他。”

"I see no occasion for that. You and the girls may go, or you may send them by themselves, which perhaps will be still better; for, as you are as handsome as any of them, Mr. Bingley might like you the best of the party."

“我不用去。你带着女儿们去就得啦，要不你干脆打发她们自己去，那或许倒更好些，因为你跟女儿们比起来，她们哪一个都不能胜过你的美貌,你去了，彬格莱先生倒可能挑中你呢?”

"My dear, you flatter me. I certainly have had my share of beauty, but I do not pretend to be any thing extraordinary now. When a woman has five grown up daughters, she ought to give over thinking of her own beauty."

“我的好老爷，你太捧我啦。从前也的确有人赞赏过我的美貌，现在我可有敢说有什么出众的地方了。一个女人家有了五个成年的女儿，就不该对自己的美貌再转什么念头。”

today is december 1st. oh, it’s my birthday! i’m so happy. so i get up very early. i wear my nice coat. mom says, “you’re so cute.” i say, “thank you.” in the evening, grandpa gives me a book. dad gives me a big cake. we eat cake and drink milk. my pet dog, winnie is eating cake, too. my family says, “happy birthday to you!” today i’m so happy.

As you may know the Spring Festival is falling on February 1st this year. Its the most important holiday in China and offers the best occasion for family reunion. However, over the past 3 years I missed the reunions due to tight work schedule. Now that I have wrapped up my work for this year, I would like to go back to my hometown to pay filial piety to my parents and help my sole brother prepare his wedding on January 28th.

Its indeed double happiness for my family that I would like to be part of. Coupled with the official holidays for the Spring Festival, I will have two weeks off which will definitely gear me up for better work in the new year. Im looking forward to your kind answer.

Best regards,

George Chen

Dear friends,

I am Li Ming, president of the Students’ Union. I am writing to call on you to give up smoking.

Some students in our school have been caught smoking, which has become a cause of concern. Medical studies show that smoking is harmful to our health because of the poisonous chemicals produced when cigarettes are burning. Both smokers and non-smokers are affected by the poisonous matter. So the number of people who suffer from lung cancer and other breathing-related diseases has been on the increase. Therefore, smokers should give up this bad habit as soon as possible.

Let’s develop a healthy lifestyle! Let’s take action from now on!

[号召同学珍爱生命远离烟草倡议书英文作文

When people succeed, it is because of hard work, but luck has a lot to do with it,too. Success without some luck is almost impossible. The French emperor Napoleon said of one of his generals, “I know he’s good. But is he lucky?” Napoleon knew that all the hard work and talent in the world can’t make up for bad luck. However, hard work can invite good luck.

When it comes to success, luck can mean being in the right place to meet someone, or having the right skills to get a job done. It might mean turning down an offer and then having a better offer come along. Nothing can replace hard work, but working hard also means you’re preparing yourself opportunity. Opportunity very often depends on luck.

How many of the great inventions and discoveries came about through a lucky mistake or a lucky chance? One of the biggest lucky mistakes in history is Columbus’ so-called discovery of America. He enriched his sponsors and changed history, but he was really looking for India. However, Columbus’ chance discovery wasn’t pure luck. It was backed up by years of studying and calculating. He worked hard to prove his theory that the world was round.

Success that comes from pure luck and no hard work can be a real problem. For example, consider a teenage girl who becomes a movie star.

Imagine she’s been picked from nowhere because of her looks. She is going to feel very insecure, because she knows she didn’t do anything to earn her stardom. On the other hand, think about an actress who’s spend years learning and working at her craft. When she finally has good luck and becomes a success, she will handle stardom better, she knows she earns it.

People who work hard help make their own luck by being ready opportunity knocks. When it comes to success. I think that hard work and luck so hand in hand.
