Dear Sir,

I understand your well-respected college offers a number of places to overseas students every year, and I am writing to enquire about the application procedure.

I am at present a student at Mary High School, Hong Kong, where I have been studying for the past five years. I passed the Hong Kong Certificate of Education Examination last year with distinctions in English and History, and credits in Economics and English Literature. My advanced-level subjects are History, Economics and English Literature. In addition to these subjects, "Use of English" is also a compulsory subject because a pass in English is a minimum requirement for admission to most faculties of the University of Hong Kong.

Apart from academic work, I have been actively involved in extra-curricular activities. I am Chairman of the English Club and I have represented my school in many inter-school contests.

On the advice of my friends, I have decided to further my studies in England because I wish to widen my horizons and benefit from the scholarly heritage of your country.

I wish to continue to study the above-mentioned subjects at your college in the 2006/7 academic year before I sit the Advanced-level Examinations in England.

As regards my character, Mrs. Chen, my Principal, and Mr. Huang, my English master, have agreed to act as my references.

As I come from a family of fairly limited means, I would like to know if there is any financial assistance available for overseas students.

Attached is a summary of my qualifications for your reference.

I should be grateful if you would kindly consider my application and notify me of the result at your earliest convenience.

Should you require any further information, please feel free to contact me or my references.

Yours faithfully,

Lily Chen

在一个瓜果飘香的秋季，我们告别了母校，迎来了初中的生活。而初中生活的第一课就是军训。

军训这一课是磨炼意志和思想的一课，从站军姿到齐步走，跑步走，都给了我们人生的启示和感想。

第一天我们就学习了站军姿，抬头挺胸，双手紧贴裤缝线，两脚的脚后跟并拢，脚尖分开60度角。一开始我们很兴奋，自然做的也很认真，很正确。可过了一会儿，虽说太阳不太大，但是我们还是一个个动来动去，扭来扭去，像一个个小蚯蚓。教官见我们“新官上任三把火”就赶紧喊起了口令，让我们站好，不许动。站了10分钟的军姿，我们个个都腰酸腿疼，就更别说说话了，有的同学不顾三七二十一一屁股坐了下来，有的同学像豹子一样跑去喝水。一天下来，我们的军姿也站的差不多了，也便一次站的比一次轻松，回家也迫不及待的展示给父母看，仿佛我们都是一个个小军人。

后来我们又学习了稍息立正，停止间转法，齐步走，跑步走……5天我们学习了很多东西，似乎我们真的成了一名既能做好训练，又能守纪律的军人。时间如流水般流去，五天的军训转眼就成了回忆。我们要和与我们一起训练的教官分别了，心里充满了不舍。军训很辛苦，辛苦得有收获，辛苦得有意义，辛苦得让人难忘。难忘我们军训时的挥汗如雨，难忘训练时严厉的教官和我们开玩笑时的样子，难忘在最后一天会操时我们的卖力表演，最后依依不舍的分别。

可是我们终于成功的完成了5天的军训，过的快乐而又充实。军训告诉我们：世上无难事，只怕有心人，只要认真对待困难，我们就永远不会倒下。

初一:飘落的樱花

暑假的来临，对于一个学生来说，是一件十分兴奋的事。学习了一个学期，终于可以让我们放松放松了。我打算好好的充分利用一下暑假，使暑假过得既快乐又有意义。暑假第一天我便为自己制订了一个计划表，贴在我卧室最显眼的地方，时刻提醒自己，督促自己。

我的暑假计划内容非常丰富。

首先，为了不使我的视力下降,所以我为我自己制定了三条规定。

1、尽量少看电视。

2、每天坚持做眼保健操。

3、合理使用电脑。虽然电脑也容易损坏眼睛，但是电脑已成为我学习和生活中的重要部分，也是我家必不可少的一件“日常工具”了。

另外，为了使我学习能更上一层楼，写作水平能有所提高，我要求自己做到：

1、每天坚持写日记。

2、预习下学期课文。

3、认真做完暑假作业。

除此之外，平时爸爸妈妈常说我知识面不广，了解的课外知识少，我便又对自己提出了以下要求。

1、多看课外书。

2、每天坚持背一首古诗。

3、上网或看报了解新闻时事。

最后，为了自己在学习和娱乐的同时，也不忘好的生活习惯，又计划以下几点。

1、自己的房间要保持整洁、常常打扫。

2、早睡早起。(这一点我怀疑自己可能做不到，所以要求爸爸妈妈加强监督。)

3、自己的事情自己做。

计划制订好后，最重要的是我自己要按计划执行，不能光说不做。同时，我每过五天我便会对自己做自我检查。希望自己能过一个既快乐又有意义的暑假。还有在暑假里认真复习英语，不然会忘记的。

一年级英语作文四：My Lovely Teacher

there is a lovely teacher in our class. we like him as our friends. we would like to tell him everything, happiness and sadness. he helps us on our lessons and guides us on other things. i am happy to have such a good teacher.

Friends are important for us, everyone has their own friends, we share sorrow and happiness with our friends. We are making new friends now and then, but it is hard to find the genius friends, the trust between friends are hard to build. If the trust exists, friends can talk anything, they are willing to show who they are in front of their friends. While if the trust doesn’t exist, the friendship is not real deep, people will ask you when they are in trouble. The real friendship is built on the basis of trust. My best friend will never ask me to do thing all the time, instead, she cares about me, and comforts me when I am upset. That’s a real friend.

朋友对于我们来说很重要，每人认都有他们的朋友，我们和朋友分享喜怒哀乐。我们会时而不时地交朋友，但是交到真正的朋友很难，朋友间的信任很难建立。如果信任存在，朋友间可以讨论任何事情，他们愿意在朋友面前展示真正的自己。

然而如果信任不存在,友情就不会很深，人们只会在他们有困难的时候才叫上你。真正的友情是建立在信任的基础上的。我最好的朋友永远都不会一直叫我去做事情，相反的，她一直关心我，当我感到烦恼时，给予我安慰。这是真正的朋友。

下雪了。大地白茫茫的一片。好美啊！

我兴高采烈的跑到了屋外观看雪景。只见雪花纷纷扬扬地从空中飘下来，雪花落在树姑娘的身上，树姑娘好像披上了一件雪白雪白的婚纱；雪花落在屋顶上，屋顶好像带上了雪白雪白的帽子；雪花落在了马路上，马路好像系上了雪白雪白的哈达。

雪花落在了大地上，大地好像盖上了雪白雪白的羊毛毯。我双手一接近晶莹的雪花，想数一数它有几朵花瓣，谁知它一到手上就不见了，变成了小水珠。过了一会儿，我的全身落满了雪，像一个小雪人似的。

啊！我爱这美丽的雪景！

Today, my parents took me to my grandfather’s home.I talked with my grandfather for a little while and then I played with my brothers and sisters.

After a while, my elderly brother suggested going to the park and having a rest.“That’s a good idea. ” I said.Then we prepared for the outing.However, after lunch, the sky turned dark and rained heavily.Therefore, our plan was an impossible due to the bad weather.How pity it was!All the afternoon, we could only have fun in house.

Winter vacation one day, my mother came home from work. Just rushed into the door shout: "month, guess mother bring to you?" "It must be delicious." I answer without thinking. "No." Mother said, and took out a small box handed me from behind. I took the box curiously, cant wait to open a look, turned out to be a lively and clever bird. I took it, carefully looked at carefully.

This should be a just flying bird, corners of the mouth of the yellow is not faded. A taupe feather plump neat, small round eyes black light, looked around in horror.

Accidentally, the birds escape from my hand, toward the window, want to fly out? That a head hit the window and fell on the windowsill, but it still unwilling, stare blankly with wings to fly. I cant help but poor bird, I think, the bird should live in the bosom of nature, free to fly. So I said to mother: "mom, lets put the bird! See mom and dad, birds worry more afraid of ah." Mother looked at me with indecision, then use appreciation tone, said: "my son is grown up. Birds have given you, you have the final say." I thanked my mother happily, holding the bird ran downstairs.

Downstairs to the ground, I gently loosen the hands and the little bird "ceng" to fly to the sky, fly away quickly. I seem to see the bird to fly back to the flock, nestled in the father and the mother bird bird side, telling the story of todays experience, has a good boy...

寒假的一天，妈妈下班回家。一进门就兴冲冲地喊：“月月，猜妈妈给你带来什么?”“肯定是好吃的。”我不假思索地回答。“不对。”说着，妈妈从背后拿出一个小盒子递给我。我好奇地接过盒子，迫不及待地打开一看，原来是一只活泼机灵的小鸟。我小心翼翼地捧起它，仔细端详着。

这应该是一只刚刚会飞的小鸟，嘴角的嫩黄还未褪去。一身灰褐色的羽毛丰满整洁，一双圆溜溜的小眼睛乌黑光亮，惊恐地四下张望。

一不小心，小鸟从我手里挣脱开来，朝着窗户飞去，想要飞出去吧?没想到一头撞到窗玻璃，落在窗台上，可它仍然不甘心似的，扑楞着翅膀想要飞起来。我不禁可怜起小鸟来，我想，小鸟应该生活在大自然的怀抱里，自由自在地飞翔。于是，我对妈妈说：“妈妈，咱们把小鸟放了吧!看不到爸爸妈妈，小鸟多着急害怕呀。”妈妈惊疑地看着我，然后用欣赏的口吻说：“我的儿子长大了。小鸟已经给你了，你说了算。”我高兴地谢过妈妈，捧着小鸟飞快地跑下楼去。

来到楼下的空地上，我轻轻地松开双手，小鸟“噌”地飞向天空，很快地飞远了。我仿佛看见小鸟飞回了鸟群，依偎在鸟爸爸和鸟妈妈的身边，诉说着今天的经历，故事里有一位善良的少年……

这篇关于高一年级作文精选：中国足球，是无忧考网特地为大家整理的，希望对大家有所帮助！

同学们是不是经常为作文的写作而烦恼呢?只有不断的练习和阅读才能提高自己的写作水平哦!精品学习网为大家提供了高一年级的作文精选：中国足球，希望同学们认真阅读，有所收获。

在学校的一块不怎么标准的足球场上，我们初三一帮人和初一的一帮人，约好了在星期五放学之后踢一场球赛。

到了时间，铃声一响，所有人都一窝蜂地奔向足球场，看着面前的一个个瘦弱的小朋友，从心底里就觉得这是一场没什么悬念的比赛。双方除了人数正规以外，都是十一人，也没有什么别的了。

可是，就是这一场以大欺小的战斗中，我没这些“高手”却没占到什么便宜，也正是这一场球赛，让我看出了足球的正真意义，往小了说是团结协作，往大了说，是看出了中国足球失败的原因。

刚开赛不久，我们初三的凭着“娴熟”的技巧拿下一分，直到结束比赛，我们还是不能挽回1比3的局面，初三惨败初一，其实这个结局是料定了的。

在比赛中，惨败的原因大致有三个：一是我们初三认为只要凭着自己的“高超”技术可以带球绕过十一个人直接拔脚射门就行了，因为对方是初一的“小朋友”，但主要是有些人没有意识到足球比的是团结协作，而不是个人表演，从而可想而知表演者是怎样当着全场人的面将球踢飞到场外或轻而易举的被别人截下的。这只是初一大获全胜的原因中的一个，更是初三惨败的重要原因之一。

二是急功近利，当然，都想进球是好事，但是过于急功近利事情总是物极必反，在还看不见球门在何方时就大脚射门，无异于赌钱，虽然有时也会有碰上死耗子的时候，但单靠这这微乎其微的机率下获胜可能吗?

三是没有将踢足球放在心上，有些人就像电线杆子似的立在球场之上，滥竽充数。见球来了而且是离自己比较近的时候就上前走几步，见别人来抢了就一脚踢开似乎很神气的样子，也不管球传给谁了。这是不尊重足球和没有拼搏意识的人，我在踢得时候校徽不小心被别人碰掉了，那个人大喊，你校徽落了，我才不会上你的当，球大于天，要专心踢球，如果我这个

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.

Computers started to become popular with big companies in the 1960s.

Computer

You’ve probably known about computers your whole life. But computers have not really been around for very long. Computers started to become popular with big companies in the 1960s. Computers didn’t become widespread in homes and schools until the 1980s.

HOW DO PEOPLE USE COMPUTERS?

People use computers in many ways. Stores use computers to keep track of products and check you out at the cash register. Banks use computers to send money all over the world.

Computers help teachers keep track of lessons and grades. They help students do research and learn. Computers let you hook up to networks (many computers hooked together). They let you hook up to a worldwide network called the Internet.

Scientists use computers to solve research problems. Engineers use computers to make cars, trucks, and airplanes. Architects use computers to design houses and other buildings. The police use computers to track down criminals. The military uses computers to make and read coded messages.
