The New Year opened the door for us, and the winter holidays crept to our side. Like last year, I made a "winter vacation plan" early. I dont want to waste this good time.

The first thing is to combine. During this time, I kept reading and writing more. Now I have read six good books and wrote more than ten compositions. I also borrowed the book of the fifth grade from my relatives, and when I had time, I would turn over to look at it, learn the skills, and memorize the formulas.

When youre tired, take a break, watch TV, play computer games, or play games with your neighbors. Of course, you cant spend more time playing than studying! Otherwise its not good. In our stage, the most important thing is to learn, so, can not be too fond of play.

The second point is to help my parents to work. Our parents come back from work and have to do housework. They are very tired when they are busy. When we are sons and daughters, we should help them to do what we can to help them relieve some of the burden. In this way, not only can we exercise our practical ability, strengthen our constitution, and be able to be praised by our parents, not an arrow three?

Third, last point. I want to get into the habit of going to bed early and get up early. In this way, you can kill two birds with one stone, which can enhance the health and fuel economy. Wouldnt that be great?

In winter vacation, I must strictly follow the plan book, happily in the big year, over winter vacation!

现在，我很苦恼。我买了一本英语书，可是我不知道它的意思。我一点也看不懂。我想，也许我要好好的学习英语。只有这样我才能学会很多知识，才能看懂英语和别人交流。我要对自己说一句：加油!

I was depressed because I couldnt understand an English book after I bought it. I could understand nothing. I thought maybe I should study English hard and only by this could I learn a lot of knowledge and understand English aw well as communicate with others in English. I told myself, ‘just go’.

When I was small, I like to eat a lot of food, but I have a habit, I will not eat up all the food, I just like to taste all of it. When my mother saw this, she felt bad for me, she told me that all the food was the farmers’ hard work, I should not waste it. Thinking about this, I felt so shameful about my bad behavior, I decided to eat up the food. Wasting the food should be condemned, especially in the cities, people like to waste the food, they want to keep thin and only eat small portion. Now, the government advocates people clean the plate, this movement is welcomed by the public, more and more people have the idea not to waste the food.

在我小的时候，我喜欢吃很多东西，但是我有一个习惯，我不会把东西吃完，我喜欢浪费食物。当我的妈妈看到这些，她对我感觉不好，她告诉我所有的食物都是农 民辛勤劳作的，我不应该浪费食物。想到这些，我对自己的坏习惯感到惭愧，我决定吃完所有的食物。浪费食物应该受到谴责，特别是在大城市，人们喜欢浪费食 物，他们想要保持苗条，只吃小部分。现在，政府提倡人们光盘，这个做法得到了大众的肯定，越来越多的人意识到不浪费食物。

时间过得飞快，转眼间，一个寒假过去了，但是，在寒假里发生的所有一切，我永远也不会忘记，特别是去欢乐谷的那一段时间，虽然那是短暂，但它却像一块巨大无比的石头，一直填在我的脑海里，搬也搬不开，小学生作文：我的假期生活。

事情是这样的，一天小姨发信息来，说要带我来，说要带我们去欢乐谷，这个消息使我们家的笑声沸腾起来，特别是我，一听到欢乐谷这三个字，一蹦三尺高，简直不敢相信，顿时都快高兴得晕了过去，因为欢乐谷是我梦寐以求的地方。

盼哪盼哪，终于让我盼到了，小姨抱着愉快的心情，和我们坐着105路汽车，直奔欢乐谷。

到了欢乐谷，我真想要马上冲进欢乐谷，玩个够。

我们在欢乐谷里玩了许多刺激的游戏，例如矿山车，雪山飞龙，完美风暴，太空梭，还有……但是玩的，同时也最搞笑的还是北极探险了。

我们排了很长的队，终于功夫不负苦心人哪，轮到我们玩了。我和弟弟兴冲冲的坐上车子，拿起手枪，准备出发。已经出发了很久了，可我只有118分，但是，弟弟却有227分了，我不服气，便大声的冲着弟弟嚷：“喂，你不要打了，你已经有228分了！”弟弟见了，说：“我还要打到400分呢！”我不服气，便打了他一下。他就打了我一下。一会儿，我们便打起架来，后面的大姐姐看了，情不自禁地开怀大笑。

时间过得飞快，转眼间，寒假过去了。但是，欢乐谷的身影却永远留在我的心里。

马上过春节了，不仅是我，大家都急着做年夜饭吧。

这几天晚上我连晚上做梦都看见的，是那桌上琳琅满目的美食。这边有烧白，鸡汤，糯米珍珠丸子，还有红糖果果。那边有蒜蓉开背虾，粉蒸肉，夹沙肉，还有糖醋排骨。除了这些美味的，菜品，还有很多想都想不到的美食，总之都是我的最爱。不过最好从梦里醒来，要让它变成现实，只有自己努力了。

一起床我赶紧洗漱后，将自己想吃的菜全部写在了一张纸上。又把家里缺的菜品和作料，写的另一张纸上。我们拿起这张单子，拿上一点钱，就跑去超市采购所有的菜品。我从来没有哪一次吃饭买过那么多的菜，占了我们的大半个客厅。

一开始，外婆先从一个箱子里拿出汤圆面和汤圆心各放在一个碗里。接着又把碗里的汤圆面，捏成一个一个的小球。这些过程都是拿来享受的，见到这些的我，就赶紧把袖子捋起来，洗了好几遍手，跟外婆一起包汤圆。我先站在外婆旁边，看见外婆很轻松很熟练的包了一个汤圆，我还以为包汤圆是件很容易的事情呢。

我先拿起一小块汤圆面，揉成圆形，再用大指和食指，在中间，按一个小孔出来，慢慢的把旁边的汤圆面，压得稍微薄一点。接着从另外一个碗里拿出勺子，挖一小勺的汤圆心放在汤圆面的那个小窝里。谁知道我在封口的时候按的太用力了，把汤圆面的按裂了。我赶紧把裂的地方补起来，以免汤圆心漏出去了。

接着就是封口，我慢慢的把旁边的面推起来，让汤圆心子我下滑，这样就可以把口封起来了。我每次在封口的时候都不能把汤圆搓圆。我就只能想尽办法先把口给封上，再慢慢的把汤圆给搓圆。我又开始认为撮汤圆是一件再简单不过的事了，可是我就用平时的方法来做，越搓越扁，越搓越扁。后来我把手供起来了一点，终于把汤圆搓圆了，我的第一个汤圆就这样诞生了，我轻轻地把它捧着，放在一块垫有纱布的盘子上。

我发现包汤圆还是挺好玩的，我就一直包，包到汤圆面和汤圆心都没有了。我们把要吃的放在锅里煮，把剩下的就放在冰箱急冻室里。下次过年我还要和外婆一起包汤圆。

My summer holiday is coming soon， I start to make some plans about my vacation. I go to travel every year， this time， I want to travel to Tibet， it is the place I always want to go to. I have heard about Tibet many times， my mother’s friends tell me so many wonderful things in it， so I want to go to Tibet. This summer I will go to Tibet.

我的暑假很快就要到来了，我开始为我的暑假指定了一些计划。我每年都去旅行，这一次，我想要去西藏旅游，那也是我一直想要去的地方。我经常听到有关西藏的事情，我妈妈的朋友告诉我很多关于那里的美好事情，所以我想要去西藏。这个夏天我将要去西藏。

One day, my mother bought two littleRabbitsfor me. I’m very happy.

From that on, the two little rabbits became my good friends. They have two little ears, red eyes, with white and fat boby. They’re marvellous.

Everyday, they play with each other happily. One day, I couldn’t find them. I asked my mother: ”Where are they? ” My mother told me that She didn’t know. At last, I found them in the grass. They were very dirty. I was angry, but when I looked at their lovely faces, I was happy again.

I love my little rabbits, and they love me. They are my good friends forever.

Mostly, I went to school to have lessons this week. It was hard but we must experience, wasn’t it? But on Saturday I finished my first learning. And the second learning will begin on Aug 1st. I can have a break and do what I want to do. On Saturday I went shopping. Indeed I didn’t buy many things. I just wanted to relax. And then I played on the computer, sang , watched TV, etc. I just wanted to amuse myself. I went to swim on Sunday, although I didn’t swim very well. I felt cool during this hot time. I also played with my mother. She couldn’t swim so I taught her. I sometimes played a trick on her. I had a good time there.

【二】

This week I didn’t do many wonderful things. I went to learn developing film with my classmates on July 1st. It was easy and we all got good marks. On July 4th, I went to school to learn, because I will be a junior three student soon. We would have to learn some lessons in advance. The weather was very hot. But I didn’t feel that learning lessons was boring. Some teachers are new. They are good I think, although they are all looked strict. And the lessons were not too bad. This week was the beginning of this summer holiday, but it was really typical

【三】

This week I mostly stayed at home and did some homework. Last Saturday HP6 had just come out. And many Harry Potter fans went to buy it. I did’t buy it because it was too expensive, but I downloaded it on the Internet. It was in English. Many people went on translating as soon as the book came out. I also took part in it and became a part of the translating group. From this group, I first realized that my English was so poor. I needed to look up in the dictionary all the time. It was really troublesome. But I withheld and withheld. I had translated many paragraphs. I was the youngest among the translators, but I didn’t feel there was much pressure. This work was hard but I really felt happy. We had already finished nearly 20 chapters

【四】

I went to the Forest Park with my old friend this Thursday. Although it was hot, we had a wonderful time there. We played a lot, such as corsair, bumper cars, Arabian Flying Blanket and so on. We felt excited indeed. That day was also my friend’s birthday. I bought a comic strip for her because she likes cartoon very much. She also invited me to her new flat to play. At last she gave me a heart made of crystal. She really moved me. On Sunday afternoon our translating group had finally finished all chapters! I was really excited. Although our translation was not very fluent and nice, even a little abrupt, it was our outcome. It was our effort. When I saw my name on the heroic translator list, I was really proud of myself.

【五】

On Monday the typhoon had gone. Luckily it was not hurricane. And it had only been here for 2 days. Also after this typhoon, not many people lost their lives. On Saturday I finally finished my second learning. Some students were very happy because we finished all summer learning. But some students sighed because of the heavy homework. I wasn’t sad and wasn’t happy, either. I just know we have been junior three students. We must work hard to enter a good senior high school and pave the way for the future. So heavier homework, shorter holiday and more study are all a must.

寒假英语作文-春节介绍

the Spring Festival

1 Far and away the most important holiday in China is Spring Festival, also known as the Chinese New Year. To the Chinese people it is as important as Christmas to people in the West. the dates for this annual celebration are determined by the lunar calendar rather than the GREgorian calendar, so the timing of the holiday varies from late January to early February.

To the ordinary Chinese, the festival actually begins on the eve of the lunar New Year＇s Day and ends on the fifth day of the first month of the lunar calendar. But the 15th of the first month, which normally is called the Lantern Festival, means the official end of the Spring Festival in many parts of the country.

2 Spring Festival is the most importantand popular festival in China.Before Spring Festival ,the people usually clean and decorate their houses.And they go to the Flower Fairs to buy some flowers.During Spring Festival ,the adults usually give lucky money to children.People often get together and have a big meal.Some people eat dumpling for dinner.

I love Spring Festival .

In the morning, my father went to work, my mother bought food. The house I am the only one left, I had no choice but to burn the breakfast to eat, what to eat good?

My first oil into the pot, and then open the gas stove, open a small fire, while the oil on "pa pa" rang, I know the oil is hot, quickly hit an egg into. I saw the "crackling" oil exploded.

早晨，爸爸上班去了，妈妈买菜去了。家里只剩下我一个人，我只好自己烧早饭吃，“吃什么好呢?”我自言自语说道，这时我想起妈妈早上经常给我烧煎蛋吃，那么今天我也给自己来烧一个煎蛋吃吧!

我先将油倒入锅中，再将煤气灶打开，开成小火，过了一会油就“啪啪”的响了，我就知道油热了，就连忙打了一个蛋进去。只见油"噼里啪啦“的炸开了。

After a semester busy learning, we finally ushered in the summer vacation. In order to have a meaningful summer vacation, I especially ahead of the summer vacation plans, hope I can complete according to the plan.

My summer vacation plan is mainly divided into three parts. The first part is: finish the summer vacation homework. Before summer vacation homework because I have no plan, every time is close to the school before hurriedly catch up on my homework. Plan in this summer vacation I all do for an hour every morning and afternoon summer vacation homework, I believe the efforts of the two hours a day will make me high quality finish the homework during the summer vacation. The second part is: learn to swim. Can see other children in the pool before free swimming, I very envy, also learned last year, but he did not insist on, no society. This years summer vacation, Im going to night ok and dad go to swimming pool to swim, let my dad taught me, I also want to serious efforts to study. The third part is to help my mother do housework. Already in the sixth grade, but I also seldom help mother do the housework, every time the holiday at home are bustling about mother, I just play. This summer vacation, I help my mother do one thing must be at least once a day, reduce the burden of the mother.

With the above detailed plan, I determined to: must complete according to the plan, change your procrastination is lazy, let oneself have a meaningful summer vacation.

经过一学期忙碌的学习，我们终于迎来了暑假。为了过一个有意义的暑假，我特别提前做好了暑假计划，希望自己能按照计划完成。

我的暑假计划主要分为三部分。第一部分为：完成暑假作业。以前的暑假作业都是因为我没有做好计划，每次都是快到开学前才急急忙忙的赶完作业。我计划在这个暑假里每天上午和下午各做一小时的暑假作业，相信每天两小时的努力一定会让我在暑假里高质量的完成作业。第二部分是：学会游泳。以前看见别的小朋友可以在泳池里面自由自在的游来游去，我就十分羡慕，去年也学过，但是自己没有坚持下去，也没有学会。今年的暑假里，我准备晚上没事都和爸爸去游泳馆游泳，让爸爸教我，我也要认真努力的学习。第三部分是帮助妈妈做家务。已经上了六年级了，可我还很少帮助妈妈做家务，每次放假在家都是妈妈忙来忙去，我只管玩。这次的暑假，我一定每天至少帮妈妈做一件事情，减少妈妈的负担。

有了上面详细的计划，我下定决心：一定要按照计划完成，改掉自己拖拉懒惰的毛病，让自己过一个有意义的暑假。

My experience of the winter vacation

The winter vacation goes by unconsciously. I experienced a lot and learned a lot both about subjects and life. And I want to introduce a new member of my family to you. It’s a pot of flowers.

“I still remember the flowers we buy last year. The flowers blossomed really amazing. So I buy another one this year!” as I heard my mum’s voice, a pot of flowers appeared in my house. Since then, it became the apple in my mum’s eye. But the bud didn’t open yet, so it didn’t interest me at all.

My mum took care of it every day. “Can it bloom” “Trust me, it can give you surprise.” Answer my mum. Several days later, some bud opened. The house became muchlivelier with the decoration of the floret. I admitted that I underrated it. “How gorgeous will it be” I thought.

Unwittingly and quietly, New Year’s Eve came.When all of us were watching TV, these flowers already blossomed gorgeously and exudes a light fragrance. All of us stopped from watching TV to appreciate the flowers. “See, how wonderful it is!” My mum said approvingly.

Yeah, nothing is impossible. An ugly bud can blossom to a beautiful flowers, a poor beggar can struggle to a successful business man. So throw our prejudice away, let’s judge everything with logos.

尊敬的物理老师：

因为我的大脑短路，犯了忘记写物理功课这样一个低级的错误。在这里，我对自己犯了这样令人发指的罪行，向您作出了深刻的反思和检讨。

我要向敬爱的老师做出道歉。我这种愚蠢的行为不仅拖延了老师的工作进度，而且耽误了老师看电影，吃水果的宝贵，也辜负老师对我的信任。

我知道自己的行为是非常愚蠢的。我这种对自己不负责任的行为。也可以看出我在课堂上是多么的不专心，以至于我没有听到每节课，老师在课程末尾留下作业。我这样的恶劣行为，将是很大程度低影响我未来的生活。

在此，我向您保证，我以后不再犯此类错误了。我要时刻让自己大脑中的开关处于闭合状态，并且同时保持通路。

在未来的日子里，我会积极进取，以福特先生、安培先生，欧姆先生为学习榜样。我还会仔细听课，不忽视任何一节物理学习，做好每一页的物理作业，不惹老师您生气，不辜负老师您的良苦用心，我希望老师给我重新改正的机会，让我在今后生活中向您证明我的悔改!

我的小妹，又称淘气包，真教她儿歌，她也欣然接受，这不今天我就担任起她的小老师。

听我说一句，她说一句：“小白兔，白又白。”小妹鹦鹉学舌地说句：“小白兔，白又白。”我又说：“两只耳朵竖起来。”她有一字不差地说句：“两只耳朵竖起来。”

…

就这样，一句儿歌都说完，让她重读一遍，她似乎一个耳朵进，一个耳朵出，一问三不知。我又耐下性子，就这样反反复复说十几遍，她终于有些印象，我又逐字逐句地教她一遍，过十五分钟，我再说一遍，吃饭前我又让她说一遍，一天的时间将接近尾声，我正要喝水，()忽然听到小妹口齿不清地说起来：“小白兔…

以前，她淘气地连听你数个“1，2，3，”的时间都没有，你只能跟在她的屁股后面收拾这收拾那，现在天天给她说儿歌，耳熟能详，自然说出个八，九不离十。

看来，做事就要持之以恒，不半途而废，就像教妹妹儿歌一样，最终还不是成功?我还总结出一个背书小窍门，就是隔一天背，隔一天背，接着，隔两天背，这样以此类推，就能做到长久不忘。
