暑假里,妈妈带着我去了雄伟的泰山.当我们登上泰山最高峰的时候,已经是晚霞满天了.东岳泰山是世界自然遗产之一,有许多名人在这里留下了笔墨.其中最著名的是杜甫的"会当凌绝顶,一览众山小".晚上,我们住在了山顶上.

During the summer vacation, my mother took me to the mighty Taishan. When we boarded the Taishan peak, is already sunset sky. Taishan mountain is one of the world natural heritage, there are many famous people left a pen here. The most famous is the Du Fu "would be extremely Ling, list of small hills." evening, we live in the top of the hill.

第二天一早,妈妈就把我从睡梦中叫醒了.这时候,天空上刚刚泛着白色,还有几颗星星在闪烁着.导游告诉我们,东边那颗最亮的星星是启明星.这时已经有许多人聚在日出崖上了.东方的天边越来越红,照得云姑娘的脸通红通红的.我们屏住呼吸,等待着,等待着."出来啦!出来啦!"太阳露出了头,在我们的欢呼声中,太阳从地平线上蹦了出来,光芒四射,照亮了整个大地.

The tour guide told us, the heart is the brightest star of star. Now many people gather at sunrise cliff. The eastern horizon more red cloud, as the girls face flushed red. We hold our breath, waiting, waiting. "Out! Out!" the sun exposed head, in our cheers, the sun from the horizon jumped out, shine, illuminate the whole earth.

With the general standard of living improvingand the working week becoming shorter，more andmore people are able to make a holiday trip toplaces of interest. While many like to joinpackage tours fro convenience，I prefer to traveln my own.

I like travelling on may own not only because it costs much less but because it gives a great degree of independence and freedom. Travelling on my own，I’m my own boss;and can decide when to start on my way，where to linger a little longer and which spot can be skipped over to save energy or time for another spot. I can always adjust my plan. On the contrary，in a package tour you’re deprived of as much freedom as in a military base. At the sound of the whistle，you have to jump up from a sound sleep and，with heavy-lidded eyes，hurry to the gathering place where you are collected and counted to board a coach. At the sight of the little flag waving，you must immediately take yourself away from the scenes you are marveling at and follow the guide whose sole interest is to cover all spots according to him strict schedule，regardless of the weather or your health condition.

True，you may encounter inconveniences if you travel individually，for instance，getting accommodations for the night and finding a place for meals. But nothing can be compared with the freedom which is vital to a person who takes a holiday trip mainly to escape from constraints of his routine life.

As it is known to us all, there are 55 minority groups in China, each with its traditional customs, costumes and culture. Now let’s take a look at the Tibetan Minority.

The Tibetan Minority group live in Qinghai, Gansu, Sichuan and Yunnan Province. And the highest ridge in the world─beautiful and mysterious Tibet is their major habitat .

As the fertilized prairie stretches around the habitants as far as the eyes can see, most people live on animal husbandry, raising sheep, goats, cattle and growing a special kind of plant called Qingke. On account of the unique climate, people often wear warm and comfortable boots in winter, and they are always dressed in delicate robes which are made of the fur of sheep. Often they take off one sleeve of the clothes and tie it around their waists in order to work easily and use it as warm quilts at night.

Both men and women there like wearing silver ornaments, which look very mysterious and full of magical power. And they are good at singing and dancing, and the men there can have braids too. When they meet an important guest, they will present him or her a Hada, a piece of long white silk cloth to show their respect. And they will also treat the guest to a special kind of drink called Suyou Tea, which some people find hard to enjoy.

Besides, the habitants have developed both their own written and spoken languages, and the long poems they wrote play an important role in Chinese literature. And there are many well-protected culture relics as well, taking the grand Budala Palace as an example. It is a historical museum as well as an art treasury, where people can share their spirit belief in Buddhism and get artistic entertainment of the carved paintings and the beautifully-written chirographies.

The Tibetan ethnic group is also famous for its strange custom in funeral. Thinking that the soul belongs to the sky after a person dies, they usually put the body on a platform outdoors, spray on it and wait the condors to come to eat the body. In this way, they believe the soul goes up to the sky.

The Tibetan Minority is brimming over with deep emotions. The people there are very zealous and hospitable and they live freely and happily on the spacious grassland. Their history and culture contribute to the diversity of China, so we certainly should protect them and get them popularized and let them receive great respect they deserve.

It is the Lantern Festival. My grandfather, grandmother and father are all

in shanxi. There are only my mother, my aunt, my sister and me. My mother and

aunt are looking at the computer. I teach my sister to skateboard.

First, I asked my sister to step on the skateboard with her left foot and

gently push her right foot to jump. But she jumped several times and couldnt

jump. So I asked her to stand on a skateboard with her right foot on the board.

But she could not walk two steps and fell, but she fell several times without

losing heart. Once, when she slipped more than two meters, I was happy to give

her a hand. She was also a brave and persistent person. My sister jumped up

too.

This day, although my grandpa, grandma, and father are not at home, but

this Lantern Festival I have a very happy!

My summer vacation life, is a poem, a green leaf, a song...

除了紧张、充实的学习生活外，我还拥有轻松、愉快的假期生活。那丰富多采的内容，充实了我的人生，也为童稚的学生生涯增添了几分乐趣与悠然。

茶余饭后去散步是我每天的必修课。漫步在小区的花草旁，呼吸着清香的空气，与花鸟作伴，欣赏着玫瑰的浓郁，百合的高洁，晚饭花的奇特，还有玉兰的娇美，美人蕉的绚丽,我会轻轻地对自己说：“生活真是美的。”我用真诚感受身边的五颜六色，用热情欣赏周围的姹紫嫣红。我不由自主地从内心发出：“我，属于大自然!”

更多地，我会一头扎进书的海洋，呼吸着书店、图书馆特有的那种书香的气味，感受漫步书海的乐趣。钻进历史的海洋，我会为秦始皇焚书坑儒的举动而激愤，为霸王别姬的悲惨而落泪，为诸葛亮“出师未捷身先死”扼腕叹息;漫步文学的殿堂，我渐渐体会到宝钗的无奈、黛玉的才华，体会到玛丽的倔强、科林的孱弱，体会到余秋雨的“晨雨初听”、钱钟书的“围城”……

我的暑假生活，是一首诗，一片绿叶，一支歌……

I never thought ourFriendshipcould be so long. We are classmates, not only are still friends. We was like peas and carrots, no words do not say, learn from each other, to long for short.

Name is ling-ling jin, she is my good friend, she is fat, black hair like a black waterfall down vertically, a pair is eyes, his mouth with a knife. She commanded, considerate, in her heart is how to think how to say, serious and responsible. Speak is a disadvantage, but she is hurt others self-esteem.

We have two years of friendship, can be said to be my friend stay together life learning the longest time of friends. But sometimes, the cup of friendship, we sometimes jokes, but dont to heart. Until that time, we continue to cold for three days, meet dont say "hello", also no longer together, become a stranger, with indifference. Several times we all want to apologize, to lose me, she in and out of a person, very lonely, she and I justdont willing to give up this friendship. After days of ideological struggle, I decided to be friends, although the fault is not in me, we still made up. I often think: true friendship is to pass the test. From now on, we cherish the friendship

True friendship, it is purity transparent ice and snow, the cold the unity, the more tight.

True friendship is a clear spring water, not only to the column into the withered life vitality, but also can wash the stain of the mind

Original all stronger after the test of friendship, will never be apart.

我从来都没想过我们的友谊会如此长。我们不仅是同学，还是好朋友。我们形影不离，无话不说，相互学习，以长补短。

她是我的好朋友，叫金玲玲，她微胖，乌黑的头发像黑色的瀑布垂直下来，一双水灵灵是眼睛，嘴边有一条刀痕。她心直口快，体谅别人，在她心里是怎样想就怎样说，认真负责。不过她有个缺点，就是有是说话伤别人的自尊。

我们已两年的友谊，可以说是我的朋友当中待在一起生活学习最长时间的朋友。但有时，友谊之杯也会裂，我们有时开玩笑，但都没放在心上。直到那一次，我们持续三天冷漠，见面也不打招呼，也不再形影不离，成为陌生人，以冷漠相待。有好几次我们都想道歉，失去我以后，她进进出出都一个人，很孤独，我和她都舍不得放下这段友谊。经过几天的思想斗争，我决定和好，虽然错不在于我，我们还是和好如初。我经常想：真诚的友谊是要经过考验的吧。从此，我们更加珍惜这个友谊

真正的友谊，是冰雪纯洁透明，越冷越团结得越紧。

真正的友谊，是一涧清澈的泉水，不但给即将枯萎的生命柱入活力，而且还能洗涤心灵的污点

原天下所有人的友谊经过考验之后更加坚固，永不垮。

People often say that gold and silver are the most valuable things in the

world.But

I dont think so. In my opinion, to read books is more valuable than

anything else.

The old saying “To open a book is always helpful” clearly tells us how good

it is to read a book.

Books are our friends. They introduce us different kinds of knowledge. They

lead us down the road to success.

Books are our teachers. They teach us troth, science, literature, and

philosophy of life. Besides, they increase our knowledge, enlarge our

experience,strengthen our character and do many other things which we can not do

without them.

Books tell us what is good and what is evil. And only books can tell the

good from the bad.

Therefore to read more books is the best policy for our young students.

News, used to be the most dont like to see it. Since the childhood has been like watching cartoon and foam. Now over the years is already 15 years old girl, the adults always said I dont understand, I also often because of his bad temper, or not doing things. "Knowledge too little" finally let me find the dawn, from then on began to like the news.

Compared to the past, only reading does make me understand a lot of knowledge, also became the academic leaders, but its a downright failure in life. While reading can also know society, but after all the writers praise is the truth in life, and that I love watching cartoons, and eulogize justice and goodness, degeneration and reject evil. In such an environment, my heart has been living in the white cloud, so that as the growth of the age, heart is still very naive. But I will contact with the reality of society, the essence of this society is not absolutely fair, not cheated can only let oneself become strong. But when he does not know this, just complain, disposition also become bad. Fortunately, when I was going to despair, when the news took me, no let me into the who also do not know to have bottomless pit.

Know only after watching the news of the worlds largest and I small. The content of the news is very rich, I also have different preferences, from country to country, down to between people. I see from a real case: "some of the good qualities: honesty, integrity, good Samaritan, wisdom... how important it is for this society!

新闻，以前是最不喜欢看的。从小到大一直喜看动画片和泡沫剧。现今过了年已是十五岁的大姑娘了，大人们常说我不懂事，我也常因自己脾气不好，或是不会处理事情而烦恼。一句“见识太少”终于让我找到了曙光，从此便开始喜欢上新闻。

对比以往，只读书确实让我懂了不少知识，也成为了学业上的佼佼者，但在生活上却是一个失败透顶的人。虽然读书也可以认识社会，但毕竟作家们歌颂的都是生活中的真善美，以及那我爱看的动画片，也是讴歌正义和善良，贬低和排斥邪恶势力。在这样的环境影响下，我的心一直生活在洁白无瑕的云端，以至于随着年龄的增长，心确仍然很幼稚。但我终究要与现实的社会接触，这个社会的本质就是没有绝对的公平，要想不吃亏就只能让自己成为强者。可惜当初的自己并不懂得这点，只是一味的抱怨，性格也变得恶劣。幸运的是，当我快要绝望的时候，新闻拉住了我，没有让我滑向那个谁也不知道有没有底的深渊。

在看了新闻后才知道世界之大与我之渺小。新闻的内容很丰富，我的喜好也不尽相同，上到国家与国家之间，下到人与人之间。我从一个个真实的例子中看出：“人的一些美好的品质：诚信、正直、见义勇为、智慧……对于这个社会是多么重要!

My ambition is to be a teacher.Because I love the children. I want to stay with then. Then I feel happy and young. And the most important thing is I can teach them many thing. I will tell them love is very important. I will try to love others around you. Then others will be friendly to you.The world will be more and more interesting.Do you think so?

To make the goal ,come true,I will study hard.

我的梦想是成为一名教师。因为我喜欢孩子们。我想留在那。然后我感到快乐和年轻。最重要的是,我可以教他们许多事情。我将告诉他们爱是非常重要的。我将试着去爱周围的人。然后别人会对你友好。世界将变得越来越有趣。你这样认为吗?

目标,成真,我要努力学习。

In 2014, a show called Where Are We Going, Dad was popular around China, in the show, five famous stars and dads with their children went to the countryside to experience the life.

This is the first time for the audience can look at the celebrities’ children, the kids are so lovely that all the audiences love them. Now a new show which is similar to the mentioned show becomes a new hot topic, but this time, half audience love the stars’ kids, the ones who don’t like them think that the kids are not as lovely as the ones before, even look ugly. So the audience speaks bad words in the Weibo, showing their dislike. As an outsider, I think it is so cruel to the kids, they are so young and innocent, they don’t know about the world, why should they deserve those vicious words.

Imagine if they are your kids, what will you do? People should be mercy to the kids.

在2014年，一个叫《爸爸去哪儿》的节目火爆全中国，在节目中，五个著名的星爸和他们的孩子下乡体验生活。

这是观众第一次有机会观看名人的孩子，这些孩子都很可爱，所有的观众都喜欢他们。现在一个新的类似的节目成为了焦点，但是这一次，只有一半的观众喜欢明星的孩子，不喜欢的人觉得有些孩子不像之前的可爱，长得不好看。因此观众在微博上对这些孩子留下恶言，以此来表示他们的不喜欢。作为一名局外人，我觉得这对孩子来说很残酷，他们是那么的年轻和天真，对世界都了解不深，为什么他们要承受这样恶毒的话。

想象一下，如果这是你的孩子，你会怎么做呢?人们应该对孩子仁慈点。

I enjoy reading books very much, because there are lots of interesting

things in them. Two years ago, I didnt like reading very much. I had plenty of

time, but I spent lots of time on playing with computers. When I was very young,

I didnt think reading book was interesting, because I found nothing more

interesting than the computer games. Ive changed now. I enjoy reading novels,

because therere lots of interesting stories. I love to read Harry Potter.

Thats a good novel. I know that it is one of the best-sellers in England. Im

always lose myself in the interesting stories. From joozone.com. I hate the

words like "to be continued" in a novel. That makes me very sad, because I dont

know the end of the story. I also hate the words like "the end", because I want

to read more. Some of my friends think that Im strange. Maybe you can find the

interesting things in a book, so dont waste your time in the computers any

more. If you read very much, you will get lots of knowledge.

My Home

My home is on the first floor. There are two bedrooms， a kitchen and a living room. I’m a child. I have a nice bedroom. In my bedroom， there is bedroom， a closet， an air- conditioner and so on. My closet is green. My bed is blue. I love my bedroom very much.

The Rules of Making Friends

We all like to make friends, we live in a society that we need to communicate with others. Without a friend, one can never express his emotions, no one share his sorrow and happiness. Making friends balances ones emotions, you can talk to friends any things, like secret, which you dont want to share with our parents. But here is the fact that not everyone is suitable to be friend, we need to obey the rules. First, the guy must be honest. Honesty is the base of the being friends, to be frank and then to be close. Second, there is something common in you two. The same interest always brings two hearts close, the more something in common, the better, thus he will be your best friends, you can share things with him. Making friends is a big deal, cause if you make the wrong one, you may get the negative thing from him.

我们都喜欢交朋友，我们生活在一个社会，需要彼此交流。没有朋友，一个人不能表达他的情绪，没人分享喜怒哀乐。交朋友能平衡感情，你可以和朋友谈任何事，比如你不会和父母分享的秘密。事实上，并不是所有的人都适合成为朋友，我们需要遵守原则。第一，那个人必须诚实。诚实是成为朋友的基础条件，闯开心扉然后变得亲近。第二，你们两个之间有共同点。共同的兴趣让两颗心靠近，越多共同点越好，因此他会成为你最好的朋友，你可以和他分享事情。交朋友是一件很大的事，因为如果交友不慎，你可能会感染他的一些恶习。

Mid-Autumn Day，all the country is celebrating. The streets are full of

people， the loves are holding each other tightily.Everyone has his day.However，I

am lonely.No one to hold，no one to kiss，no ont to talk! I was walking around the

street without purpose，seeing the lovers kissing，watching the fireworkes

alone，walking backe room whist.

Suddenly，i think i must be good to myself.So i decied to bue a present to

myself.I know I will be good soon，and will find my Mr.Right.So tonight， a little

teddy bear will sleep with me.And i know：i will have another teddy bear as a

present that not bought from myself!!!

Chusok ("fall evening") is a Korean "Harvest Moon" (Han-gawi) festival set

on the 15th day of the eighth lunar moon. Chusok (韩国中秋节)， also known as the

Korean Thanksgiving or Mid-Autumn Festival， is one of the most celebrated Korean

holidays. It occurs during the harvest season. Thus， Korean families take this

time to thank their ancestors for providing them with rice and fruits.

The celebration starts on the night before Chusok and ends on the day after

the holiday. Thus， many Korean families take three days off from work to get

together with family and friends.

The celebration starts with a family get-together at which rice cakes

called "Songphyun" (蒸糕) are served. These special rice cakes are made of rice，

beans， sesame seeds， and chestnuts. Then the family pays respect to ancestors by

visiting their tombs and offering them rice and fruits. The Koreans visit the

graves of their ancestors to bow and clean the area for the coming winter. In

the evening， children wear their favorite hanbok (traditional Korean clothing)

and dance under the bright moon in a large circle. They play games and sing

songs. Like the American Thanksgiving， Chusok is the time to celebrate the

family and give thanks for their blessings.

Community activities include masked dance， Kanggangsuwollae， an ancient

circle dance， tug-of-wars and the tortoise game， kobuk-nori (乌龟游戏)， in which two

men dress as a tortoise and tour the village dancing and performing for food and

drink. Most of all， Chusok is a time to give thanks for the autumn harvest and

reaffirm familial and community ties.

When you need a lot of money, you first thing you do is to borrow money from your friend, while doing this sometimes may do harm to your friendship. First, your friends may not have too much money at hand, he or she maybe suffer from the lack of cash flow at that moment. Everyone has their own worries, when you borrow money, they always have to struggle for a while, their hesitations make you begin to doubt your friendship is true or whether your friends treat your as real one. Second, most people cant return the money in time, because they have all kinds of difficulties, this will make your friends in a awkward situation. They are considering whether to ask you return the money, if they do, this will make you embarrassed; If they dont, they will lack of money. So it is better not to borrow money from your friend.

当你需要很多钱的时候，你第一件事做的就是向你朋友借钱，然而这样做有时候会伤害你的友谊。第一，你的朋友也许没有很多的钱在手上，他或她可能遭遇着流动资金的不足。每个人都有他们自己的担忧，当你借钱的时候，他们总要挣扎一会，他们的犹豫让你开始怀疑你们之间的友谊是否真实或者你的朋友是否把你真当朋友。第二，大部分人不能及时还钱，因为他们有各种各样的困难，这会让你朋友出于尴尬的境地。他们考虑着是否叫你还钱，他们叫了，会让你尴尬;如果不叫，他们就缺钱。所以最好不要向你的朋友借钱。

I like sports, because doing sports is really a good thing. Firstly, it

helps me keep healthy. Exercise is one of the most active and effective means to

enhance the physical health. Secondly, doing sports is a good way to relax. When

you are upset, sport may pull you out from depression. Finally, it’s easier to

make friends while take part in sport activities, because you have the same

interest. It’s important for making friends. All in all, I get a lot from

sports.

The Olympic Games, first held in 776BC, has a history of more than one thousand years. The modern Games is held every four years. Many countries try their best to bid for hosting the Olympic Games. And every country does its best to get more medals in the Games.

There are five rings on the Olympic flag, which are considered to symbolize the five continents: Europe, Asia, Africa, Oceania and America. The Olympic motto is: "Swifter, higher, stronger." The Games can promote the understanding and friendship among different peoples and different nations.

In China, students work so hard, they study day and night, for the purpose of getting the high mark, so that they can go to a better school, which will bring them more promising future. To get the study time as more as possible, some students move their books to the study room, they want to occupy the seat, so they put a lot of books as the sign that the seat has been taken by someone, other people can’t take this seat. In my opinion, studying hard is a good thing, working hard will lead people to success, while taking the seat for a long time is not a civilized behavior. It is a kind of wasting resource, when students are not here, but the seats are empty, they should be left for other students to study.

在中国，学生很努力学习，他们白天和晚上都在学习，只为了得到更高的分数，这样他们就可以进入到更好地学校，能给他们带来更加光明的前途。为了尽可能地更多时间学习，一些学生把他们的书本搬到了自习室，他们想要占位置，所以他们放了很多书，作为位置已被人占有的象征，别人不能做这个位置。在我看来，努力学习是一件好事，努力工作能让人们成功，但是长时间的占据位置不是文明的行为。这有点浪费资源，当学生不在学习时候，位置也是空的，他们应该把位置让给别的学生来学习。
