放假那天，老师在黑板上布置的作业比较多。对于我来说，老师布置的寒假作业要全部完成还是需要很多时间的，因为又是很难，又是很多。由于寒假作业比较多，需要合理的安排好时间才能完成，所以我制订了一个寒假学习生活计划。

我的计划是这样的：每天上午把在新华书店买的《语文寒假作业》和《数学寒假作业》各做完一页(两面);每天上午进行30分钟以上时间的课外阅读;上午做完寒假作业和课外阅读后剩下的时间自由活动，可以看看电视，玩玩电脑游戏等。中午午休睡一个小时后，就要完成下午的安排了：每天下午坚持写一张毛笔字，学一个小时的电脑应用知识，读熟一篇好文章后再读给家长听。最后是在每天晚饭后睡觉前写一篇日记：可以写发生的事情，自己的心得体会，心情故事和读后感等;睡觉前再钻研一道奥数题，最后枕着精彩的电视少儿节目催眠入睡——这可不是一个好习惯哦!

以上就是我的寒假生活计划，怎么样?我的寒假计划不错吧!我不仅要完成寒假作业，也要帮爸爸妈妈做一点事情，这样爸爸妈妈才会高兴，而且这样过得才有意义。最后，快要过年了，这是我们中华民族的重要传统节日，我在这里先祝大家心想事成，万事如意!

Halloween is an autumn holiday that Americans celebrate every year. It means "holy evening，" and it comes every October 31， the evening before All Saints Day. However， it is not really a church holiday， it is a holiday for children mainly.

Every autumn， when the vegetables are ready to eat， children pick large orange pumpkins. Then they cut faces in the pumpkins and put a burning candle inside. It looks as if there were a person looking out of the pumpkin！ These lights are called jack-o-lanterns， which means "Jack of the lantern".

The children also put on strange masks and frightening costumes every Halloween. Some children paint their faces to look like monsters. Then they carry boxes or bags from house to house. Every time they come to a new house， they say，"Trick or treat！ Money or eat！" The grown-ups put treat-money or candy in their bags.

Not only children， but most grown-ups also love Halloween and Halloween parties because on this day，they can disguise themselves as personages or ghost as their imaginations will lead them. This bring them the satisfaction of being young.

It was raining when Tom was on his way home. He opened his umbrella and walked faster. Suddenly he saw an old woman staggering forward with a stick in her hand. She hadnt got an umbrella with her and was wet all over. Tom went up to her and tried to share his umbrella with her. But the old woman was tall and he was too short to hold it high enough. Then he saw the old womans stick and a good idea came to him. He tried hard to tie the stick to the handle of the umbrella. Then the umbrella was long enough for both of them. The old woman thanked him again and again. Then they went on walking home.

当汤姆在回家的路上时突然下起了雨。他打开伞走得更快。突然，他看见一个老奶奶蹒跚着拄着拐杖。她没有伞，全身都湿透了。汤姆试图和她共用一把伞。但老奶奶个子高高的，他太矮了不能把伞举得足够高的。然后他看到了老奶奶的拐杖，于是有了主意。他努力把拐杖粘在伞柄上。然后伞就足够高来遮挡他们。老奶奶一再向他表示感谢。然后他们继续走回家。

Nowdays, with the rapid development of the road, cars have been playing an increasingly important role in our day-to-day life. It has brought a lot of benefits but has created some serious problems as well. Traffic safety as the most importent one, is closely related to everybodys business.

This phenomenon exists for a number of reasons . Some of the accidents are due to mechanical problems. As the vehicles in the road become common, the function of vehicles has improved and the speed is getting faster. However, most of them are the results of careless and reckless driving, which could not be avoided. A lot of people disregard traffic signals and rules. They drive regardless of speed limits, run through red lights, drive in the wrong direction, talk and laugh while driving, and turn at will without giving signals. They even dont slow down while approaching crossroads. So many people violate traffic regulations that we cannot put too much emphasis on the importance of traffic safety. Meanwhile, we can not ignore the fact that there are many problems existing in the design. They are all important reasons accounting for this phenomenon.

Some effective measures must be taken to slove this problem. The major cause for traffic accidents is people’s lack of safety awareness. Completing a safety driving education course is a very important way to reduce the number of traffic accidents. The key point for this issue is people’s awareness towards safety. It is a long-term goal rather than a single course for safety driving. The best way to solve the troubles is that we all abey the traffic rules. First, we cant get through red light and must observe traffic order. Secondly, tell our relatives not drive after drinking. Then, we should be care about road damage and inform relevant departments to solve the problems early. Finally, an active part in social activities, protect our order society! Another measure is improving the traffic condition by add traffic signal and other traffic safety facilities。Only when everybody takes traffic safety as their own business, can we achive safe driving and walking on road.

Last but not least, I hope we can have a good futere , and I believe we can do it！

暑假马上就要结束了，我将以新的精神面貌开始新学期的奋斗。“天行健，君子以自强不息。”我在新学期要做到：

一、做时间的小主人

吃过时间亏的我，在这学期一定要珍惜时间。早读、运动、学习一样都不拖拉时间，特别是写作业时提高效率，做时间的小主人!

二、读书学习有安排

1、每天写完作业后，我要抽出大约半小时的时间来读课外书，丰富课外知识，增加词汇量。

2、上课认真听、善思考、勤作答，让老师对我刮目相看!课后，必预习、认真写、必检查，绝不有一点马虎。

三、劳动最光荣

在学校，我要一丝不苟地当好值日生，勤打扫、勤保洁、让大家有一个宽敞又整洁干净的学习环境

四、严守纪律起表率

课上，我不和别的同学说废话，管住自己;做课间操时认真做，不和同学打架、说话。

五、阳光体育我行动

在学校课外活动时间，练习跑步、打篮球、跳绳等体育活动，在运动会的时候，我要全力以赴，为班里赢得一份荣誉!

六、踏实工作小助手

在学校，我一定要当好班干部，做好老师的小助手，帮老师做好每一件事，为班级尽我的一份微薄之力。

新学期，新气象。我一定按上面的几点做，使自己尽善尽美!

在过去的征程中，曾拥有过欢知，拥有个阳光，这都已成为永远的记忆，现在加上一把锁将它封锁起来，摆在我们面前的一切都是新的，看呀?新的学期正在向我们招手。经过几年的锻炼，我们不都是一个个战士，抹去心灵的灰尘，拿上我们的武器，整装待发，新学期的目标向我们冲击!

在新学期里，我有一个新学习目标--不做语言的巨人，要成为行动的主人!用冲锋无往的实践精神，探寻未知世界的生命真谛。我知道了成功不是靠梦想来实现，而是靠自己的行动......

当然，在新的学期中，在学习要有新的成绩，这就要不懈地努力!付出一份努力才会换取一份收获。学习并不是一种兴趣，而是一种责任，是我应该做而且必须做好的事情，同时学习必定会有负担。没有苦的、累的过程，就不会有进步和提升，无论是过去，还是未来不都这样的道理吗?我把自的喜悦，悲伤都化作前进的助力和动力，就会因此不断克服困难取得新进步。成就的是我们的喜悦，成功背后是我们辛勤的汗水，没有耕耘就哪有收获，没有付出就哪能有所得。我再次踏入大学，就更应该好好珍惜这段宝贵的时光充实自己，把自己的理想变为势不可当的动力。

1、学好自己的专业课。不管说自己以后会不会做这一行，既然已经进入学习的时间了，就不要对不起自己，好好学。在生物等学科方面多下功夫。利用课余时间多看看书，个人方面应该多加强实践能力为以后社会实践打基础。

2、早上早起读英语背单词，这个学期要过四级。(第一次没有过的原因自己应该很清楚：四级好过，但也不是轻而易举就可以拿下)背新概念英语，提高口语能力!同时练练听力，扩大词汇的积累量，积极为英语四级考试做准备。

3、多看些文学方面的书，多泡图书馆!不要放弃自己的文学梦想。要多看看那些大家的作品。有机会积极写些随笔，多去图书馆看书，积极投稿，同时和志趣相投的朋友经常交流。

4、合理掌控时间：事分轻重缓急，人应自控自觉除了积极主动的态度，还要学会安排自己的时间，管理自己的事务。大学和高中相比似乎没有什么太大的区别，每天依旧是学习，每次考试后依旧是担心考试成绩……不同的只是大学里上网的时间和睡觉的时间多了很多，压力也小了很多。一开始是抱有此种想法的我并不明白时间是自己合理规划的，随着经历了专升本的压力，渐渐我明白，"时间多了很多"正是大学与高中之间巨大的差别。时间多了，就需要自己安排时间、计划时间、管理时间。安排时间除了做一个时间表外，更重要的是"事分轻重缓急"。……手勤快些，多在博客上写些东西，来反省自己，思考生活中的问题!同时上网多转转论坛，积极利用时间来学习。

5、关注时事，开拓自己的眼界!多看书报杂志，经常走出去看看。两近一远。开阔眼界，以游会友。既扩大了视野，有提升了交友能力。

6、保养好自己，健康饮食，锻炼身体，学一到两个实用技能。目的是多接触些人，(周末骑自行车去外头转转)!

7、在政治上要向党组织靠拢。我还是要积极入党，原因很简单-只有不断提升自我素养才会拥有更大的成功。

8、感受努力的快乐，享受胜利的喜悦。这是我所喜欢的，兴趣就是我最大的动力。积极投入自己喜欢的事业当中去。

我们要定好目标，执着信念，永不言败，一起因目标而努力，因梦想而精彩，塌塌实实地一步步走下去。固然，成就和荣誉往往令人羡慕、钦佩，但是"千里之行，始于足下，"要想使理想成为现实，积累是必不可少的，我们应该从现在做起，从点点滴滴做起，一步一个脚印塌实地朝着宏伟的目标迈进。

新学期，为我们提供了崭新的园地，但是需要提醒的是：荣誉的桂冠往往要荆棘编就，成功的道路往往由汗水铺通，征途决非一帆风顺。它需要忠贞不渝的追求，朝气蓬勃的热情，脚踏实地的努力，持之以恒的攀登。所以，要培养坚忍不拔、吃苦耐劳的精神。决心学习的人，得有经受磨练的思想准备，要有高远的志向，要有学习的热忱，在困难和挫折面前，不灰心丧气，把坚韧不拔的毅力体现在学习之中!

莫泊桑说："人生活在希望之中，一个希望破灭了或实现了，就会有新的希望产生。"新学年就是新的企盼、新的希望，新的征程，新的收获。新学期，新起点，新面貌，让我们憧憬更美好的明天，让我们再一次踏上征途!

她是一个很平凡的人。一张白皙而以俏丽的脸上；两道细溜溜的眉毛；一双小而有神眼睛，薄薄的嘴唇，常常挂着恬静的微笑。她个子不高，站在我们中间像是我们的一员。

她是一个很幽默，可爱的人。一次她在黑板上画了一只猴子，指着画，请了一个开小差的同学问她这是什么。她一慌之下把monkey说成了lizard。陆老师瞪大眼睛，装出一脸狐疑，轻声地问：“同学们，你们看到过像这种品种的lizard吗？下面一阵哄堂大笑。老师及时纠正说：“这是monkey，以后上课要认真听。”

有一次，有位同学上课在开小差，陆老师轻轻地走过去，拍拍他的肩膀说：“革命尚未成功，同志仍需努力啊！”小朋友有错误时，陆老师从不正面批评而是用巧妙的语言给予提醒。

在她的英语课上总是充满了欢声笑语，我们也越来越喜欢英语了！

In the 30 days of the winter vacation, I also want to some of my winter vacation plan.

On the first day of winter vacation, I will look over the final exam papers review once, and then do some exercises.

In the New Year to come, tidy up all the information about learning well, back to their hometown to play with my friends. My winter vacation plan is like this, what about you?

I Lin Wei wish you success in the New Year!

在这寒假的30天里，我也想好了我的一些寒假的计划。

在寒假的第一天，我会先把期末考的试卷复习一次，然后再做一些练习题。

在寒假的第二天到第五天，我会把老师布置的所有作业都完成好，再看一些课外书和资料。

复习到差不多的时候，我会去买一些六年级下册的书籍和资料来预习，并背诵每一篇课文和词语的理解，数学就买一些练习题来做。在新年要到来的时候，就把全部有关学习的资料整理好，回到老家和朋友们玩耍。我的寒假计划就是这样，你们呢?

我林薇在新的一年里祝你们马到成功!

For I want to spend my holiday fully,so I plan to go on a trip,I want to go to hongkong for 2 weeks,because it is not only a shopping paradise but also

The heaven for children.

It’s very far away ,so I plan to go there by plane,it is the most convenient way to go there,

And I decided to stay there for 2 weeks ,while I can thoroughly to feel the local customs there

I also want to go taiwan,I want to go to a concert in xiaojudan,such as listen to a concert .

光阴似箭，日月如梭，一个漫长的暑假结束了，重新回到学校见到了熟悉的同学们、熟悉的学校、新的班级、新的老师。新学期就意味着我们要更懂事，更加听老师的话，也说明了我们的学习负但要更大，我们不能整天只想得玩了，要抓紧学习。在这个学期里，我要百尺竿头，更进一步。

我首先制定一个学习计划：

1、上课的时候，我要认真听讲，不做小动作，不和同学交头接耳，对于疑难问题，虚心向老师和同学请教。

2、要认真完成老师布置的所有作业，做到一丝不苟。手工作业和家庭作业也要按时独立完成。

3、要做好语文课的课前预习。要预习好反义词、近义词、多音字。课文之间有趣的段落要先把它在书上划下来或记下来，有便于复习。课后题要认真书写，不能三心二意。

4、利用课余时间，多读书、多看书，丰富课外知识。

5、下课不追逐打闹，不打架，不大声说话，不制造噪音，不带玩具进校园，不带三无进校园，严格按照七字歌的要求去做。

6、要节约用水，不玩水，不浪费水，做一个文明的人。

7、多做清洁，讲究卫生，多洗澡，洗头，洗脚，常换干净的衣服，做一个卫生的人。

8、在家里，要多帮助家长打扫，做力所能及的事，如扫地、洗碗、擦桌子等。

总之，新学期，我们应该更加努力的学习。

一个人的生命纪录是被不断更新的。也就是说在一个人的一生中有许多次开始跟结束。每年是一个新的开始，每一天是一个新的开始，甚至每一分、每一秒都是新的开始。面对这瞬息万变的世界，我们注定要用新的面貌来适应它。

我也迎来了我新的开始，因为新学期即将开始。

我必须调整好精神状态，绝不能用假期的散漫习惯对待学习，要积极调动学习的热情，兴趣，全身心地投入到学习中去。

要珍惜时间，集中精力搞好学习。任何人的成功都离不开勤奋，因此我要上好每一节课，积极思维，大胆发言，善于发现问题，解决问题，当天的学习任务当天完成，决不拖到明天，只有这样才能成功。

关注新闻，关注国家大事，这样才能了解更多知识。

其次，每周做周小结，把一周学习的内容进行复习，巩固。

新学期开始了，生命纪录再度更新。一切已成过往，何必再去记挂呢？它们只不过是旧档案而已。在新学期伊始，以一个全新的面貌来面对即将开始的一切，不留遗憾，向旧纪录挑战是我们应该做，也是将要做的。来吧，让我们一起展现一个新的自我！

今天，我做了一个决定，有的时候我会不自信。所以我要每天早上起床后对着镜子说一遍加油。因为我认为那样会使我变得自信。那样，我就可以大胆的去做一些我想要做却会紧张的事。现在，我要说一句：加油!

修改后：

My favorite TV program is Animal World. It’s very interesting and exciting. There I learn a lot kinds of animals.

Some people think some animals are dangerous. They may hurt us humans. We can kill them. I can’t stand the idea. Each animal has its reason to live on the earth. They are important for the world. They keep a balance. If somebody breaks it, we humans may not be able to live on the earth.
