书是人类进步的阶梯，书就是一名良师益友，帮助你，教导你。

当我写到这是，有人肯定会说：“读书多没意思，学校里就学那么多，何必回到家还要读呢?”我会肯定的告诉他：“书中自有“黄金屋”读书时乐趣无穷的，没限制没压迫，而不是要死读。”

我非常喜爱读历史书，历时能告诉我中华上下五千年有丰富的民俗，风气及朝代盛衰，做人的哲理，《四大名著》我读完了使我受益匪浅，比如《红楼梦》告诉人们心正不含杂念歪门邪道，曹雪芹的“一把辛酸泪，满纸荒唐言。都云作者痴，谁解其中味。”渺渺几字我觉得就包含的无穷的韵味，《水浒传》生动的人物性格，《三国演义》三顾茅庐、火烧赤壁等故事让我沉醉在书中不能自拔，被书的魅力所深深吸引，书就像一片汪洋大海等待我们去探索研究发现虽然有时会碰到大风大浪但是只要勇往直前我相信你会到达成功的彼岸。

真如冰心所说的：读书好，多读书，读好书。

今年的寒假下了一场五十年来最大的雪，给我们的生活带来了许多不便，当然，对我来说，也是一件很开心的事。

听说乡下这几日天天大雪纷飞。雪小的时候还好，顶多鞋子弄湿一点也没什么，大时就不好办了，衣服、鞋子中真是无孔不入呀，最不好的是交通不便。但我的心却早已飞到了乡下，因为下雪是我最喜欢的。我想，我二哥哥家辉家别墅后面有一块空地，下雪时一定会积很多的雪，可以让我玩个够。而且，我的三个哥哥因为放假，大家都到齐了，是一个好机会。

所以，昨天一早，我就早早起来了，吵着要爸爸开车到乡下去，想不到爸爸爸爽快地答应了。过了20多分钟，我们就到了家辉哥哥家。迎接我们的是一脸坏笑的家辉，我刚一下车就有很多碗大的雪球飞过来了。我东躲西藏，还是有几个还出击中了我。我睁眼一看，怪不其它几个哥哥也是一脸怀笑。

“好，有你们好看。”我怒气一下子升了上来，赶紧跑去捏起了雪球，和他们拼上了。丁丁哥哥也跑了过来帮我。我们就这样两个对两对个干起了雪仗。30多分钟后，我们一组胜利了，家辉他们跑进了屋。我也跑进屋，再去看大人们，他们竟打起了双扣、麻将，正高兴着呢!原来不止我想到乡下来呀。

Nature is great, ecology is complicated, life is a mystery, but we know too little, less than "ephemera to heaven and earth, and are one of the sea corn." The earth is rich and colorful, the myriad of object. A blade of grass, a tree, an animal, a group, a person, a family, a nation, a society. Is the result of a natural progress. Natural animal, natural plant, all the plants in the natural, natural all life is useful. Their existence is useful. To think of the mother at the sight of the forest, wood; At the sight of the rivers of power; At the sight of the grassland, to think of red meat and cashmere sweater; To think of at the sight of the animal, can eat, can use, can be used as a medicine.

Cherish the animal is the wealth of society, we must protect. Although some are common, but beneficial to human animals, we should also take care of. Plants but also the friend of human. Plants can help people purify air, reduce noise, keep the soil and water conservation, windbreak and sand-fixation, regulating climate. Really done a lot of contribution for the human.

大自然是伟大的，生态是复杂的，生命是奥妙的，而我们了解得太少了，尚不及“寄蜉蝣于天地，渺沧海之一粟。”地球是丰富多彩，物象万千的。一根草，一棵树，一个动物，一个群体，一个人，一个家庭，一个民族，一个社会。都是自然不断进步的结果。天生的动物，天生的植物，天生所有的植物，天生所有的生命都是有用的。它们的存在就说明有用。一看到森林，就向想到母木材;一看到河流就想到发电;一看到草原，就向想到牛羊肉和羊绒衫;一看到动物，就向想到能不能吃，能不能用，能不能入药。

珍惜动物是社会的财富，我们必须保护。一些虽很常见，但对人类有益的动物，我们同样应该爱护。植物也是人类的朋友。植物能够帮助人们净化空气，减少噪音，保持水土，防风固沙，调节气候。真是为人类做了不少贡献。

If set up a holiday, I want to set up a reading festival.

There is a celebrity once said: books are the ladder of human progress. Can learn directly from the book in predecessors experience, knowledge to make our trips up again on the way forward little, little detours. Reading can broaden our horizons, cultivate our feelings... The benefits of reading.

But now, we learn a lot of pressure, although we also want to read more books, but the heavy academic burden and a variety of extracurricular cram school, the remedial class is our breath, where still have time to read more books? So I can look forward to establish a special reading festival.

In reading festival on this day, we dont have to go to school, dont do your homework, you can enjoy all the extra-curricular, explicitly swim in the sea of knowledge. Can communicate with friends their own reading experience, express their own unique insights. Can also and students to act out the scene in the book! Reading festival can each month once or twice a week.

How I hope to have a reading festival!

如果设立一个节日，我要设立一个读书节。

有一个名人曾经说过：书是人类进步的阶梯。从书中可以直接学到前人的经验，知识使我们再前进的路上少摔跟头，少走弯路。读书可以开阔我们的视野，陶冶我们的情操……读书的好处数不胜数。

可是现在，我们的学习压力很大，虽然我们也很想多读书，可是过重的学业负担和五花八门的课外补习班，辅导班压得我们喘不过气来，哪里还有时间多读书呢?因此，我特别期盼能设立一个读书节。

在读书节这一天，大家不用上学，不用做作业，可以尽情地看课外书，痛痛快快地在知识的海洋里畅游。可以和同学朋友交流自己的读书体会，表达自己的独特见解。还可以和同学把书中的情景表演出来!读书节可以每个月一次或每周两次。

我多么希望有一个读书节啊!

Tom’s Room

Look! This is Tom’s room. His photos are on the wall. His T-shirt is on the

bed. His baseball bat is behind the dresser. The keys are in the drawer. The

computer is on the desk. Where is Tom’s baseball? Oh, It’s under the bed. What

is on the floor? They are Tom’s shoes, socks and computer games. What do you

think of Tom’s room?

Interracial marriages can cause many problems within the family. Due to the fact that the couple has a different family background, culture, and custom, and social class level, many disagreements can occur. Religion can be a problem. If the two has a different religion then the other one, there is a problem. Because some religions celebrate certain holidays while others dont. In Christianity, for example, Christians celebrate Christmas while Buddudists dont. Eating habits can also be a problem. One might eat certain food the other dont or dislike. After all, their offspring will encounter problems too. Childrens who are mixed are not likely to be accepted in certain areas in a community. They often have a hard time fitting in. Interracial marriage is not a good idea, but it is still alright to marry someone who is different than you.

跨种族婚姻会导致许多问题在家族内部。因为这对夫妇有一个不同的家庭背景、文化和习俗,和社会类级别,会发生许多分歧。宗教可以是一个问题。如果两个都有不同的宗教,那么另一个,有一个问题。因为一些宗教庆祝某些节日而其他人没有。例如,在基督教,基督教徒庆祝圣诞节而佛教徒不。饮食习惯也会成为一个问题。有人可能会吃一些特定的食物其他不要或不喜欢。毕竟,他们的后代也会遇到问题。儿童谁是混合不太可能被接受某些地区的一个社区。他们常常很难适应。跨种族婚姻并不是一个好主意,但它仍然是好的比你嫁给不同的人。

Today, with the development of economy, more and more children receive high

education. The government has put forward the policy to let children get free

and future career. In the future, theSchoolwill pay more attention to the

students ability and their talents, so more class will be opened to them. They

can choose the class that they are interested in. This will happen since middle

school, and students learn knowledge with less pressure. They can enjoy the

class.
