冬天到了，北风呼呼地吹着，天冷极了。鹅毛大雪从天上飘落下来，像仙女撒下的小花。雪停了，远山变白了，大树变白了，整个世界都变白了。

Winter is coming, and the north wind is blowing. Its freezing cold. Large snowflakes falling down from the sky, like the fairy planted flowers. The snow stopped, the distant mountains turned white, the trees became white, and the whole world became white.

小朋友们可喜欢雪了。他们在雪地里有的滑雪，有的溜冰，还有的打雪仗。我和妈妈一起去堆雪人。妈妈滚了一个大雪球当雪人的身子，我滚了一个小雪球当雪人的头。我找来纽扣、胡萝卜、辣椒给雪人安上了眼睛、鼻子、嘴巴，妈妈找来小桶、扫帚当雪人的帽子和手。雪人堆好了，我和妈妈围着雪人又唱又跳。

The children love the snow. Some of skiing in the snow, some ice skating, and snowball fights. My mother and I went to make snowmen. Mother rolled a big snowball, and when the snowmans body, I rolled a small snowball, when the snowmans head. I found the buttons, carrots, peppers to the placement of the snowman eyes, nose and mouth, mom to kegs, broom when the snowmans hat and hand. The snowman was piled up and my mother and I sat around the snowman singing and dancing.

冬天的雪真美呀！这洁白的雪给人间带来了欢乐。

The snow is beautiful in winter! The white snow brought joy to the world.

似乎好久没有见过这么大的雪了。

当真是鹅毛大雪!本来一天都只是朦胧的小雪，到下午，突然就飘起了一大团一大团的雪花，好几片粘在一起，就像是夏日里的柳絮纷飞，在空中上下飞舞着，向六面折射着温柔的白光。大概只有这时才确能感受到谢道韫那句“未若柳絮因风起”的独特妙处了吧!真真儿的，再没有比柳絮更贴切的比喻了，只有柳絮才可以恰如其分地比拟出雪花的洁白和轻盈了。

第二天早上醒来，赶快套着睡衣扑到了窗前，雪花用了一夜的时间完全实现了统一天下的夙愿，率先占领了整个长安城，盛唐的角角落落都铺陈起雪的盛礼。

31楼的视角极好，可以俯视一整片的低矮楼房。房顶上全积了一层厚厚的雪，且不复有一个脚印，我想，大雪无痕应该是最高贵的激情吧。看着那毛绒绒——可不，正是毛绒绒——的积雪，我心中痒痒的，直想去摸上一把。冲下楼，一阵寒风夹着雪粒吹过来，哇，好冷!看来我起得还不够早，地上已经有了几行脚印，为单调的白添加了些许趣味。小心翼翼地往光洁的雪地上一踩，脚下沉睡的积雪被突如其来的脚丫惊醒，“吱呀”地叫了一声。踩雪的快感让我又忍不住迈出了下一步，再下一步。转头，只见隔壁家店里养的那只白猫悄无声息地从一辆裹满了雪的轿车下钻出，奶白的毛发几乎与雪融为一体，浅蓝的眸子在雪地中忽闪了几下，接着慢悠悠扭转身去，留下一串梅花诗行。

一路上树最显眼。树叶是坊头的扁舟，装载了一船的雪。各树有各美：松树摇身一变成了公主的蛋糕裙，梧桐树更文艺了，那些枝叶落尽的树，静默的黑，配上纯凝的白，背景是黯蓝的天空，竟构成了一幅画。然而新生了鹅黄色嫩叶的柳枝才是至高无上的美——新春的生命与冬雪交相辉映，点缀着清晨的校园，让人不禁感叹：自然所迸发出的生命力是最美的!

经过了一节早读语文知识的洗礼，来到操场，雪地又一次给予了我极其的惊喜——那样宽阔的雪地，还是可以自在奔跑的，在哪里还能找得到呢?混沌的孩子们完全成了脱缰的野狗，扑向了茫茫大自然中。突然，一个雪球“呼”的拍在了我的左脸上，回头一看，那个偷袭者已跑远了。我心头竟然涌起一股欢愉，抓了一把雪追了上去。但是，不管追到与否，我已不惦念心间。

因为雪、脚印、树枝和孩童，已然构成了最美的冬景，带着自然所独有的伟力，还有什么可奢求的呢?

Autumn wind, there is a box of colorful crayons. Look, he painted the leaves yellow, yellow leaves drift floating, drifting away the red sun.

The wind of autumn brings the smell of sweet smell. Pear is fragrant, apples sweet, this sweet smell of smell, brought the peasant uncles laughter.

The wind of autumn has a golden flute. It tells everyone, quickly prepared for the winter it! Small frogs quickly dig holes, ready to sleep on the United States and the United States a big sleep. Rows of geese row of good team, catch up with the clouds, go to the south.

The wind of the autumn came hastily from afar and rushed to the distance.

I love small animals, but my favorite is my little cat.

Small cat with a black and white hair, its hair is very smooth, very beautiful. It is round face, relied on a pair of like childlike eyes, a pair of triangular ears up vertical, it is very clever. It also has a long, upwardly rolled tail, four white and sharp claws.

Little cat is like fish. So I often buy fish for it to eat. I remember once, my mother bought a few fish, I put one of the fish head and fish tail to the small cat. I thought: this little cat should be able to eat it! So, I put the other fish on the table not enough time to cover, can not wait to run out of play.

When I came back, I saw the little cat eating the fish with relish, and I thought: ah! I have just gone out to play these fish have not yet covered, and now eat the cat. I just raised my stick and wanted to hit it, the little cat met, ran away, he ran and looked at me with my eyes, and wanted to say, "Little master, I am wrong! Please forgive me!"

I put down the stick, quickly ran to the cat in front, touched its head, gently said to it: "After the may not be so!" Little cat heard, like to understand my words, "meow, meow, Meow "called up.

Small cat cat and mouse is also very powerful. I remember once, I was dedicated to the work in the room. Suddenly, a mouse did not know where to jump out. I "ah!" Called up. Small cat came over and saw the mouse, it quickly went to catch the mouse. After a while, I saw the little cat who had caught the mouse, and he was eating with a jealousy! I walked over and said, "Little cat, you are awesome!

Little cat brings my life to infinite joy, I like it!

Have you seen it in winter?,

Quietly stay in the corner of the umbrella.

The dust on it is the tears of his anger.

Please dont say umbrella and cry in summer too,

For those dews are tears of happiness.

At this moment, you will think of yourself alone at home, lonely mood.

In summer, umbrellas raise their hats,

Dancing with raindrops, dancing with your thunder, dancing on your head.

At that time, how happy it was.

In winter, he could only sit quietly in the corner and cry.

The north wind with its heavy voice laughed at the spring, you look forward to the winter, you cry, ha ha ha...

Her heart broke when the umbrella did not speak.

The umbrella wants to call to the sky, but it can not.

Just ---

He wants to make one

Happy, free umbrella....

走出家门，一股清新的空气扑面而来。雪静静地下，似乎谁也没有发觉四周已是白茫茫一片。继续向前走，打开我的视野，笔直的水泥路上已经盖上了一条长长的白地毯，那么纯洁，那么晶莹，看得叫人不忍踩上去。路两边的便是两排挺拔的垂铃木，象两排整整齐齐、穿着白披风的卫士。树木被寒风剥去了盛装，静静地忍受着严冬的寒冷。

我走在街上，一阵阵风向我迎面吹来，雪花落在我的头上，身上、脸上，我被白雪笼罩着，仿佛置身于仙境之中。不知什么时候，人们就像是约好了似的，或三五成群或独自一人走出家门来感受这凉爽的气息，一些小孩子在打雪仗、滚雪球，街头一片热闹。

我站在这里，凝视着茫茫雪地上一串串深浅不一的脚印，耳边回荡着银铃般的笑声。啊，我沉浸在美好、遥远的记忆中……

1、雪花飘落在大地上，一点儿，一点儿给大地妈妈添上了白色的秀发。冬的精灵就这样来到了人间，给人一种白茫茫的感觉，看上去是那么的可爱迷人。像是一个个五彩的泡泡美丽，但又是那么的脆弱，关心的一个抚摸，轻轻的一声问候，都会给它留下难以忘却的伤痕。也许正是它的脆弱，使人不能忘记，也不敢忘记它。

2、大雪纷飞，人们好象来到了一个幽雅恬静的境界，来到了一个晶莹剔透的童话般的世界。松树的清香，白雪的冰香，给人一种凉莹莹的抚慰。一切都在过滤，一切都在升华，连我的心灵也在净化，变得纯洁而又美好。树上已披上了一件白色的纱衣，地上像铺上了一层厚厚的白棉被。大地变成了粉装玉砌的世界。啊！真美啊！我陶醉在这银装素裹的世界里！

3、洁白的雪花装点着整个黑夜，给这个黑暗的世界带来点点光明，让整个黑暗的世界获得一丝光明。但，它却不能在这个世界待得太久，当阳光冲破云彩的束缚照射在这个世界时，雪花便一点点的消逝，一层层的变薄，直到最后裸露出整个大地，它的生命过程就这样短暂而有平凡的终结了。轻轻的它从遥远的天际而来，之后又悄无声息的离去，除了记忆，不留下任何踪迹。

4、下午四点左右，太阳就毫不吝惜地射放出它灿烂的光芒，给街上的行人，路边的树木、楼房都镀上了一层刮不掉的黄金，还给我们带来一种温暖的感觉。风，像母亲的手抚摸着你的脸，暖暖的，舒服极了。而云就像一块块融化的牛奶糖粘在天空上。

5、这些雪花真像一个个顽皮的孩子，有的落在了房屋上，一座座房屋就像披上了一件白色的新衣，有的落在了那笔直的水泥路上，像铺了一条长长的白色地毯，晶莹又纯洁，看起来也很柔软，踩在上面还发出咯吱咯吱的声音，听起来是如此的清脆，有的落在了道路两旁的杨树上，两排杨树像两排站的整整齐齐，穿着白披风的边疆卫士，有的落在了远处的山上，群山换上了一件闪着银花，有深有浅，与众不同的新衣服，有的落在了碧绿的湖水上，很快被融化了，湖水上被风吹得波光粼粼，起伏荡漾，有的落在了麦田里，雪为麦田盖上了厚厚的棉被。

6、这一天天气格外晴朗，空气中带着冰雪的纯净，堆积在沟洼里的雪干飒飒的，小风一吹飘飘扬扬，想万点银粉撒在笔直的公路上，太阳光从山尖向外一喷，瞬间，在这平坦的路面上，闪着散碎，耀眼的光泽，好像是白银铺成似的。

7、寒冬中显真情。在每一个冬天，我都感觉不出寒冷，因为有爱的存在。爱可以使冰川融化，可以使人不再孤单，做事也有了动力。渐渐的，我喜欢上了冬天。每年不只盼望春天，更盼望着冬天的到来。在不断的长大中，我也学会了给予别人关爱。爱是相互的。在我心中，冬天的味道是淡淡的甜味。

8、在人们还在享受秋季带给他们的凉爽时，冬姑娘已经不知不觉地来到了我们的身边。她，来的无声无息。当下了第一场雪时，人们才察觉到她来到了。下雪了，地上铺满了白色的地毯；大树裹上了银色的冬装；房子上也重新刷了一层白色的油漆……冬天好美啊！一下子，整个世界都变成了白色，多么象一幅有诗意的图画啊！

9、冬天，它没有春天的鸟语花香，没有夏天的绿树青山，也没有秋天的果实累累，可是冬天，它默默无闻，为人们送来了一个洁白的世界。雪花从一望无际的天空中轻轻地飘落下来了，纷纷扬扬，飘飘洒洒，一朵朵，一片片，白的似银，洁的如玉，像天上的仙女撒下的玉叶、银花，像天宫派来的小天使，还像那一只只正在翩翩起舞的蝴蝶。这一切是多么的令人神往啊！

10、冬，她是圣洁的象征，当冰雪跨进冬的门槛，整个世界便被北凝结。湖面、河面上都结上了一层厚厚的冰，房屋楼阁在雪中静默，土墩、田坎在银光中陶醉，“山舞银蛇，原弛蜡旬”。如明月轻洒，树枝如梨花绽放，绵绵的“柳絮”在空中荡游，梦幻般的“天使的羽毛”从天而降，整个世界都踏进了雪国，都为之沉醉了。“红装素裹，分外妖娆。”

11、冬天到了，大地像披上了一件白色的衣裳，美丽极了！原本寂寞干枯的树枝也积上了一层晶莹洁白的雪花，真是“忽如一夜春风来，千树万树梨花开”啊！停在院子里的面包车似乎被涂上了一层香甜的奶油。灰灰的天空中，雪花纷纷扬扬，飘飘洒洒，好像远方寄来的一封封信件，又像仙女在撒着银白色的花瓣雨，像一片片鹅毛，又像一团团棉絮，轻轻地飘落下来…

12、天空中漫舞着鹅毛般的雪花，我独自走在去学校的路上。道路是如此的漫长与坎坷。寒风无情的吹着，在我脸上留下了掠过的痕迹，道路两旁的树干在风中摇曳，尤如魔鬼的手爪在伸张。雪天，路滑。不久，看到前面有很多孩子，他们都由父母护送上学，他们生怕自己的孩子滑倒，生怕自己的孩子在风中寂寞。心中不由羡慕起他们来。

13、天空渐渐暗了，似有又无的几片无的几片的云淡淡的浮在那，一种压抑的情绪成了催化剂，仿佛不久后就会有一场强大的无法预计的暴风雪。没错，会有的，只是时间的问题。开始了，有小雪花撒下了，逐渐落下了雪点，像冰雹一样砸下，接着体积不断增涨，最后那如同鹅毛般的大雪彻底遮住了人们的视线，如果你好奇，非要看一看此时的天空，那么你会发现，好像漫天的大雪都是冲着你来的，不要慌张，去感受它，你还会发现，有那么一瞬，你感受不到了周围的气息，仿佛你在慢慢的向上升着，旁边没有任何事物，只有你和雪，只有你和雪……

14、漆黑的夜晚，世间万物没有了光明。在寒风的驱使下它来到了这个黑暗的尘世，用它的洁白给世间万物带来点点光明，用它身体发出的微弱的白光来拯救这个被黑暗笼罩的尘世。黑夜就成了它最大的敌人，它拼命的追赶着，意图将黑暗消灭。冬至，夜占了上风，腊月的夜晚虽然黑的出奇，伸手不见五指，但是洁白的雪花仍在发挥着自己的力量，将这个黑夜一点点照明，直到拂晓，万家灯火通明，这个尘世获得重生，它才在阳光的协助下离开。

15、刺骨的寒风丝毫不讲情面的刮去了人们丰收的喜悦，鹅毛大雪覆盖了一切喧嚣，同时也覆盖了晴朗的心情。寒风中，“讨厌冬天”这个话题以风为载体传遍整个城市，也传到了冬天本人的耳朵里，但冬天并不伤感，她仍旧那么冷静、那么自然，她知道，时间一天天过去，她的孩子--春天，就快回家了。

16、一阵风吹过，树上的叶子窃窃私语，如蝴蝶翩动着翅膀，偶尔有几片叶子的言语被风听到，一不小心，几片发黄的叶儿依依不舍的从树间划落，就像一组意象从诗歌中飘落。在这个冬天这些叶子经过岁月的浸染，完成了它们一生的使命。叶落归根，在下一个春暧花开的日子里依然能听到它们在树枝间呤唱着春的诗歌。

17、早晨推开门出去时，刺骨的寒风呼呼地吹着，不时地向我袭来。并且，偶尔会有顽皮的小雪花纷纷扬扬地落下来，就像跳舞一样。六角形的雪花各式各样：有的像银针，有的像落叶，还有的像碎纸片…煞是好看。落在地上，仿佛给大地铺上了厚厚的毛毯；落在树上，像穿上了银装；落在汽车上，就像刚刚出炉的新鲜奶油蛋糕。这美丽的雪景使人们沉浸在清新的空气里。到处银装素裹，美不胜收。

18、寒风呼啸着，树上的叶子已经落光了，只剩下光秃秃的树干。有时，天空中不是的飘起几片飞舞的雪花，我们几乎都是温室里的花朵，享受着恬静与快乐。然而，在我们快乐的背后，却是父母留下的辛勤汗水。

19、自从冬天到来时，给了我一种清爽的感觉；给了我一种朦胧的感觉；给了我一种怀念的感觉，记得上一个冬天，那时我的感觉却是那么的轻松快乐；那么的逍遥自在。上一个冬天，一个个雪精灵飘着飘着，可爱极了，轻轻拿起来，他们总是微笑的看着我，我仿佛融化在哪冰天雪地的季节里，沉浸在那暖暖的冬天里……我那时才知道，我已经被陶醉在那样的气息里了。

20、早晨，天空不再有春夏秋天那种清亮亮的湛蓝，天边不再是金灿灿的阳光了。整个天空惨白惨白的，有点像用白纸遮盖了天空本来的面目，失去了天空原本的颜色。太阳好像也怕冷似的，躲进了像棉胎一样厚的云层。冷飕飕的风呼呼地刮着，路边光秃秃的树木像一个秃老头，受不住风的袭击，树杈在冷风里摇晃，像一只瘦骨嶙峋的手指向天空。风，使劲地透过衣服的缝隙，给你带来一瞬间的冷。大街上，买面包的小贩守在热腾腾的面包炉旁吆喝着，不同韵调的声音在大街上此起彼伏。大街上的每个人都缩着脖子，低着头，手插在口袋里，顶着风小步小步地往前走。

Goldfish is very timid, the fish in the water there are some fluctuations, they will immediately fled around, turn in the calm, you put your fingertips gently on the water, the fish will swim over, with their small Mouth sucking, your heart will be a kind of itchy feeling, you can not help but shrink back, but you will go aftertaste, you will want to do that fun again action.

One day, goldfish really die, do not know how, and perhaps I was not careful, perhaps they are too greedy, of course, more important is the weather changes so that they have become a farewell to me. I looked at the empty fish tank, and my heart was very sad. In fact, the world I live like a goldfish world, I have been living in the care of their parents, the superior life so that we partial eclipse, wayward and squeamish, really one day, we left their parents, lost the kind of favor, we It will not be like goldfish as no helpless, can not survive, right?

Winters in taipei are very cold during the evening and very windy during the daytime.

I usually look forward to the lunar new years day and the winter vacation when i can go to the village where the climate is warmer during these holidays.

Also, i look forward to seeing my grandmother, great-grandmother, and my friends in the village; i like my grandmothers food very much. Winter is the time everyone is in a festive mood.

In the city, i usually do a lot of reading at home in the winter because of the cold weather outside.

I remember 9 months ago, I was in a hurry to prepare for the college exam. I was afraid I couldnt get to my favorite school at the time. But at last I realized my dream. Now I study Chinese in my favorite university, Hanoi University.

After going to college, my life didnt change too much. Because I live and study in Hanoi, so I dont have to leave the family or rent a house. My home is not far from school, just 15 minutes by bike. But, to be honest, I prefer to live away from home, because I can live on my own, and I can feel the feeling of homesickness.

After the study, everything here is very new to me. I study in a new environment, know a lot of new friends, learn a lot of new knowledge, and so on. At first I felt a little nervous. But now Im getting used to it. The classmates of our class are all very united, often help each other to learn, there is a collective activity, we all join. When I came to school, I felt that I was not very nervous, but more and more knowledge was needed to learn. People know that Chinese characters are very complicated and difficult to remember, so every day I work hard and I will ask the teacher where I dont understand. I think college learning is not the same as high school, because high school, we students often passive learning, but in the University, we mainly study. There is no teacher to remind you of your study. You will lag behind if you dont study.

When I went to college, I was impressed by the library. The library of my school is big and beautiful. There are all kinds of books and quiet. So every day after class, I go there to study and read. There is a big stadium in my school. Every afternoon, I will go there with my friends. For example, playing basketball, dispersing and so on, it feels very easy.

During college, I had only half a days class time, so I spent the rest of the time working to earn money to increase my experience. During the University, we can also participate in community activities except for study. It is very helpful to help others, because we are all hot blooded young people.

Learning not only studies knowledge at the University, but I can learn experience. I hope to study at college in four years can make me grow up.

我记得9个月前，我还急急忙忙的准备大学考试。那时我担心我考不上我喜欢的学校。但是，终于我实现我的梦想了。现在我在我喜欢的大学，河内大学学习汉语。

上大学后，我的生活没有太大的改变。是因为我生活和学习的地方都在河内，所以不用离开家庭，也不用租房子。我家离学校也不远，只要骑车15分钟就到了。但是，说实话，我更喜欢离家的生活，因为那样我可以自己生活，可以体会到想家的感觉。

上的学后，这里的一切对我来说都很新颖。我在全新的环境里学习，认识了很多新朋友，学习了很多新的知识等等。一开始我觉得有点紧张。但是现在我已经逐渐适应了。我们班的同学们都很团结，常常互相帮助学习，有什么集体的活动，我们都参加。刚入学时，我觉得学习不太紧张，但是现在需要学习的知识越来越多。人们都知道汉字很复杂，很难记，所以每天我很努力学习，有不懂的地方我会问老师。我觉得大学的学习与高中的学习不一样，因为高中，我们学生常常被动学习，但是在大学，我们主要是自学。没有老师提醒你学习。如果不学习你就会落后。

上大学后，对我来说印象追深刻的是图书馆。我学校的图书馆很大，也很漂亮。这里有各种各样的书，也很安静。所以每天下课，我都到那里学习，看书。我学校还有大大的体育场。每天下午，我都会跟朋友去那锻炼身体。比如打篮球，散布等等，感觉很轻松。

大学期间，我只有半天的上课时间，所以我用剩下的时间打工赚钱用来增长经验。大学期间，除学习外还可以参加社团活动，这很有益与我们帮助别人，因为我们都是热血青年。

学习在大学不仅学习知识，而我可以学习经验。我希望四年学习在大学可以使我更长大。

There are four seasons a year, each season has a different view, and my favorite winter snow when the magnificent scenery. Winter, snow people seem to have come to a quiet and quiet state, came to a crystal clear through the fairy tale world. Loose that fragrance, snow that fragrant, giving a cool soothing comfort. Everything is in the filter, everything in the sublimation, even my mind is also purified, become pure and beautiful.

Dusk of snow, deep cut, as if inextricably emotional like, and like the general sea surging, to drown everything, there is a trace of open-end exposed like a sense of nudity. Snowflakes form thousands, crystal translucent, as if the expedition of the soldiers, wearing silver armor, but also like a piece of white sail in the voyage ... ...

The magnificent scenery in the snow, between heaven and earth seamless, can only see a silver, as if the whole world is decorated with silver.

After the snow, that snowy snow decorated the world, Qiongzhi Yu Ye, powder loaded jade puzzle, Hao Ran same color, really faction Ruixue Fengnian gratifying scene.

I love the snow, I love the snow, I love the winter. Winter is the ring of the soul. Winter, although very cold, but it has unparalleled warmth and hope.

Of all the festivals in China, Dragon Boat Festival is my favorite. When the Dragon Boat Festival comes, not only the family will pack the zongzi, but some communities or units will organize the group to carry on the game of zongzi. Many water towns will organize a dragon boat race, which is magnificent and spectacular.

When I was young, my mother told me that the Dragon Boat Festival in the 5th day of the fifth month of the Chinese lunar calendar was first to commemorate the great patriotic poet Qu Yuan, which gradually took the day as a holiday. My father told me that Qu Yuan is a Chu state living in the past 2000 years. He is a great poet and patriot and a loyal minister. In order to the people can live a happy life, he dared to point out the king was the wrong thing to do, so the old people loved him. But when the new king came to power, he was unconscious, and did not listen to Qu Yuans advice and claim, and lost an important battle with the state of Qin. The state of Chu was occupied by the state of Qin. After Qu Yuan heard the news, he died in the Miluo river. The local people are afraid that the fish in the river will eat Qu Yuans body, so they can put rice dumplings and other food into the river. After the death of Qu Yuan, the local legend went to the sky on a dragon boat. It was at the beginning of May each year five Dragon Boat Festival, dumplings, dragon boat racing has become an important activity.

In China, people like Dragon Boat Festival very much. Now people in the city are busy with their own work, so they cant sell their zongzi Festival, so they go to various supermarkets to buy. In the supermarket there are many types of dumplings, rice dumplings with bacon, candied dumplings, dumplings and so on, very much the pattern. After the dumplings are cooked in a pot, open the lid of the pot and smell it. It is full of the fragrance of the dumplings in the house, tasting a mouthful, and the sweet taste of the glutinous rice in the full mouth. Besides eating zongzi, people can also watch dragon boat racing. On the river, the dragon boat in front of the leading high, vivid. The whole dragon boat was narrow and long. There was a big drum in front, and one after another sat a lot of strong young men. With the sound of the drums, they paddled neatly on the surface of the water. For a while, splashing, drums, voice and the sound of refueling on the riverbank were coming up. The scene was magnificent and spectacular.

I like the Dragon Boat Festival, not only because it can eat delicious zongzi, see the wonderful dragon boat race, and more like its historical connotation. Every time I pass the Dragon Boat Festival, I can always think of Qu Yuan, think of his slamming and long sword, reciting "Li Sao" in the mouth, walking between the rivers and lakes, his loyalty and perseverance. His literary grace influences the generation of Chinese. If we compare traditional Chinese festivals to a piece of silk with jewels, then the Dragon Boat Festival is a bright pearl on the silk.

Over the past 100 years， the national revival as the Chinese peoples pursuit. In Yanan， is the leadership of the Communist Party of China National Peoples war shrine， national revival of the leaders in this map out a strategy. Time of change has left a string of visible footprint： the fight against SARS， the ruling idea practice people-centered， leaders and people in distress， won the peoples love and support. Make a spurt of progress of the Chinese economy， important resolutions to improve the socialist economic system of some problems， the cornerstone of a national revival， let me realize the whole nation of truth， to realize the younger generation to shoulder the historical responsibility and the responsibility of national rejuvenation. Also let us see the hardships course of country forward， also see today a powerful china.

In winter, all the leaves are withered, but still standing snow green pines and verdant cypresses, no matter how pressure, they wont fall down. Summer flowers, almost withered winter, plum blossoms are still blooming.

The children ran out into the open. Some were making snowmen, some were skiing, and others were skating...... There are many hibernating animals in winter, such as pythons, ants, hedgehogs, bears and frogs. They sleep on a winter and wake up in spring. Its really a long sleep!

There are many natural phenomena in winter, such as cold currents. What is cold current? It is the flow of water from high latitudes to low latitudes.

Although winter is cold, but full of fun, it is a wonderful season!

冬天的早晨，寒风刺骨，鹅毛般的大雪纷纷扬扬弥漫在天地之间。

我从窗外隐约看到一个瘦瘦的身影，他向这边走来，近看橙色的工作服上覆盖着厚厚的白雪，原来他是个清洁工人。这时他一瘸一拐的进入我们这栋楼。天啊！我简直不敢相信自己的眼睛，他居然是一个残疾人。“呼——”北风呼呼地刮，雪花飘飘洒洒。我看了一下钟表，现在才清晨7点。清洁工人正要骑着那小车子走时，他发现在一个不起眼的墙角处有一双手套，他笑了，笑得很甜。这时我想，这下好了，他不会再冻肿手了。我幻想着，这时我家的门铃响了，正是这位清洁工人，他用龟裂的两手拿着那双手套，用粗粗的声音说：“小姑娘这棉手套是你的吗？”我泪水像断了线的珠子似的流了下来，我不忍心让这位老人再去寻找失主，不由得编了一个善意的谎言：“噢，老爷爷是我的，不过你拿着暖和手吧！”他坚定地说：“孩子啊，虽然我是个乡巴佬，但绝对不会要别人的东西，我要用我自己挣得钱来买一副手套！孩子啊，你收好！”这话虽然说得有点不清楚，却深深印在我的心上，我永远忘不了那个寒风刺骨的清晨，忘不了他的笑脸，忘不了他对我说的那一席话，用自己的实力，来创造属于自己的东西！

我永远记住那北风呼啸的清晨。

一年有四个季节，而我最讨厌冬天。在我家乡，我们没有暖气系统来取暖，所以室内室外一样冷。凛冽的寒风吹在你的脸上让你感觉自己就要变成了冰棍。起床也随着温度的降低变得越来越困难。更糟糕的是，当你要写作业时，你都感觉不到自己的手了！因为太冷了！我真的很羡慕那些住在北方的人们，因为他们可以在室内享受暖气，就像春天一样舒服。噢，我真希望冬天能快点过去啊！

There are four seasons in a year, and I hate winter the most. In my hometown, we don’t have heating system to get warmed, so indoor just as cold as outdoor. The icy wind is blowing on your face and you just feel like you would become a Popsicle. Getting out of bed just become harder and harder as the temperature drops lower. What’s worse, when you try to write your homework, you just can’t feel your hands anymore because of the cold weather. I really envy the people who live in the north for they can stay inside to enjoy the heat, just like living in the spring. Oh, how I wish the winter can pass quickly！
