2. 没有信心的原因。

3. 建立信心是可能的。

Whatever one does, one should do it with confidence. If one has no confidence, there is little possibility that one would ever achieve anything, especially when one is faced with drawbacks or hardships. This troth seems to be self-evident. However, in re ality we do see a lot of people who complain that they lack the ability to do ,something or that their difficulties are too great to be overcome,For someone, this might be true. But for many others, this only shows that they have lost heart.

Why do people often feel frustrated even though they are capable of doing some thing? There are, among others, two main reasons. First, these people do not have a correct estimate of themselves. Second, they overestimate the difficulties.

It is passible to build up faith in oneself by having the right attitude towards ones own abilities. We should never underesrimate our abilities but should believe in the proverb: "Where there is a will, there is a way." Confidence is the promise for fulfilling a task successfully.

信心的重要

不管人们做什么事情，均应有信心，四六级写作《The Importance of Confidence1-信心的重要》。如果一个人毫无信心，要想取得任何成功几乎是不可能的，尤其当他遇到挫折和困难时。这个真理似乎是不言而喻的。然而，在现实生活中，我们确实碰到许多人抱怨说他们缺乏做事情的能力，或者抱怨说他们遇到的困难太艰巨以致难以克服。对一些人来说，这或许是事实，但对大多数人来说，这只能说明他们失去了信心。

为什么有些人虽然能够做某件事却常常感到灰心丧气呢，这里有两个主要原因。首先，这些人对自己没有正确的估计。其次，他们高估了困难。

通过正确地认识自己的能力树立信心是可能的。我们决不能低估自己的能力，我们应当相信“有志者事竟成。”这句谚语。信心是成功地完成一项任务的前提。

I was born in a small county which is poor. Therefore, there were no beautiful clothes or many toys. Before I went to school at six, I only played with my peers nearby. It was such a wonderful period that I would never forget. We always made our toys independently, which cost no money at all. Sometimes, parents would help making toys as well. We could play from morning to night until parents told us to go home for dinner. However, as a rural child, I must help my parents doing farm work in the busy season, such as planting and harvesting. Besides, my mother is a teacher. Therefore, she began to teach me to read and count when I was three, so I had to spend some time I study. Now, remembering it, I feel much happy rather than upset.

我出生在一个贫困的小农村里，因此不能拥有漂亮的衣服和玩具。在我六岁上学之前，我都是和邻居的同龄小朋友玩，那是一段我无法忘怀的快乐的岁月。我们通常都是自己做玩具，不花一分钱，有的时候我们的父母也会给我们做一些玩具。那个时候，我们可以从早晨玩到天黑，直到爸爸妈妈叫我们回家吃饭。但是，作为一个农村的孩子，在农忙的时候我也必须要帮忙家里干些农活，像是种植和收割这些。另外，我的妈妈是一名老师，因此在我三岁的时候她就开始教我识字、算术了，所以我还要花些时间在学习上。现在，回想起这些，我更多的是快乐，而不是烦恼。

True Happiness

"Life,liberty and the pursuit of happiness." The authors of the American Declaration proclaimed happiness to be one of the essential rights that make life worth living.William James,the first American psychologist,echoed this emphasis on happiness:"If we were to ask the question:What is human lifes chief concern?One of the answers we should receive would be:It is happiness." Every philosophical and religious system has offered its pathway to happiness for the individual and the group.Happiness has been related to pleasure,refuge from pain,intellectual contemplation,union with God,friendship,children,wealth,honor,successful activity,and even state burial with statues!Today,scientists have joined the dialogue to seek answers about what contributes to happiness or,as they call it,"subjective well-being".

If happiness is activity in accordance with excellence,it is reasonable that it should be in accordance with the highest excellence.– Aristotle The concept of happiness--while difficult to define-- is obviously here to stay.But the desire for happiness can set up expectations that are often hard to fulfill.The right to pursue happiness was conceived of as an inalienable right; the entitlement that everyone be happy was never promised.As captured by Eric Hoffer,a misguided search we hope to provide a framework that will guide you in your personal pursuit of happiness. 真正的快乐

“生活、自由和追求幸福的权利.”研究报告的撰写者们宣布美国声明是一个幸福的基本权利,让生活有价值.威廉·詹姆斯,第一个美国心理学家,回荡强调幸福:"如果我们问这个问题:“什么是人类的生活的主要关心的事吗?答案之一我们应该接受应该是:“这是happiness.”哲学和宗教系统都提供了它的通往个人和幸福

Christmas Day-December 25-which celebrates the birth of Jesus Christ, the founder of the Christian religion, is the biggest and best-loved holiday in the Christian World.

According to the Bible, the holy book of Christians, God decided to allow his only son, Jesus Christ, to be born to a human mother and live on earth so that people could understand God better and learn to love God and each other more. "Christmas"- meaning "celebration of Christ "- honors the time when Jesus was born to a young Jewish woman Mary.

Mary was engaged to be married to Joseph, a carpenter, but before they came together, she was found to be with child. Because Joseph, her husband, was a righteous man and did not want to expose her to public disgrace, he had in mind to divorce her quietly.

But after he had considered this, an angel of the Lord appeared to him in a dream and said, "Do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins."

Although the exact date of the birth of Jesus nearly 2,000 years ago is not known, the calendar on the supposed date divides all time into B.C. (Before Christ )and A.D. ( a Latin phrase, Anno Domini, "in the year of our Lord.") For the first 300 years, Jesus birthday was celebrated on different dates. Finally, in the year 354, church leaders chose December 25 as his birthday.

We went to lots of places, such as the Avenue of Stars and Ocean Park. I like Ocean Park best. The park is very big. Sitting in the cable car, you can see two hills, lots of different flowers and the sea. Some students were afraid of sitting in the cable car!

We stayed in the Shu Ren College. There are many big trees around it. We had meals in the restaurants, but I didnt like the food.

smart phones for a while when they are communicating to others.

There have been a lot of ways of acquiring knowledge. And the number is

increasing unexpectedly owing to the popularization of modern mass media.

However, reading books has always been the major and convenient approach to

knowledge. One may acquire most of his knowledge through reading books, since

they can be carried easily and read leisurely everywhere at any time. Another

equally important means of acquiring knowledge is through practice, especially

learning from others. It is unlikely for a person to get all-round knowledge by

merely reading books. As a matter of fact, genuine knowledge comes from

practice.

Although books and practice are indispensable to the enrichment of one’s

knowledge, other means shouldn’t be turned aside. With the development of IT

industry, people tend to hunt for knowledge by means of Internet. Internet is

changing people’s traditional approaches to knowledge. It has found its way into

every field of the world.

Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive. Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. We are sure that we can have a better and cleaner place in the future.

今天,我们的自然环境质量已经成为一个重要的问题。世界人口增长如此之快,世界已变得过于拥挤。我们正在利用我们的自然资源,同时与危险化学品污染我们的环境。如果我们继续这样做,地球上的生命将无法生存。关注人在环境保护方面取得了一些进展。许多国家的政府已建立法律来保护空气,森林和海洋资源并停止环境污染。

更应该采取措施解决环境问题。人们应该进一步受过教育的认识到问题的重要性,使用现代避孕方法,来保护我们的天然资源和循环利用我们的产品。我们确信我们能在未来有更好的和更清洁的地方。

The large number of our population has become one of the most serious

problems of our society. According to a recent survey of the National Bureau of

Statistics, there are more than 1.3 billion people in our country, which account

for about 1/5 of all the people in the world. the same survey also predicts that

our population will grow quickly in the years to come.

Overpopulation has brought about a series of negative effects to our

economic development and social security. In the first place, too many people

impose a heavy burden on our environment. As a result, we suffer from a shortage

of fresh water and natural resources. In the second place, as the supply of

labor GREatly exceeds the demand of the society, many people become employed.

This is a source of social unrest. Last but not least, we have to manufacture

all kinds of products to meet the needs of the people, which causes environment

pollution to our lakes and land.

Serious though the problem seems, we have to take some measures to tackle

it. On the one hand, the government should carry out more strictly the policy of

family planning, thus reducing the total number of population. On the other

hand, all the people should realize the harms of overpopulation. With the

concerted efforts of all the parties concerned, we’re sure to solve the problem

in the future.

又是一个雾霾天气，能见度不足以百米。无论是车辆还是行人都在摸索前行，没有了嬉笑，也无了鸟鸣，在这样的环境里，有的只是刺鼻的气味和满目的昏暗。

雾，原本似轻烟，如薄纱，似纱巾笼罩着大地。古往今来，它曾让多少文人墨客为之陶醉，为之倾倒。而今与这美丽的雾貌似有着一丝关系的雾霾，又犯下了什么滔天大罪?

雾霾，看似与雾有“血缘关系”，但它却和雾截然不同。雾，是由浮游在空中的小水滴或冰晶组成的水汽凝结物。有时雾出预报晴，有时雾出预报雨，似乎混乱不堪，但是只要掌握了辐射雾、平流雾的特征，多方观察，仔细分析，就能准确地抓住雾与天晴、落雨的规律，以便预测天气。这对于农业、交通、航天、航海都有用处。 而雾霾就不一样了，它是由空气中的灰尘、硫酸、硝酸、有机碳氢化合物等粒子所组成的小灰粒。
