请允许我介绍一下我的姐姐。她的名字叫卡罗尔。她又高又苗条。她有一双大眼睛，戴着一副眼镜。她的有一头很长的金发。她很有礼貌而且乐于助人。她坐车的时候愿意把座位让给需要的人。她和我有相同的爱好。我们都喜欢打网球和玩电脑游戏。我不认为她网球比我打得好。但她电脑游戏玩的比我好。如俄罗斯，砖块，泡沫等!

现今社会，科学越来越快，这使得科学重新整顿天地，让我们的生活焕然一新。以前发愁夜间的黑暗，而今暗夜变得灯火通明；以往总想尝试海中的美味，而今河海的鱼虾已成家便饭；以往总觉得家信难传，而今天涯若比邻。是的，科学带给我们的一系列问题仍然不容忽视！

科学发明在带给我们短暂快感的同时，也带来了长久问题。在以前，总有吃不完的食物，这些食物如果常温放置很容易腐坏变质，所以人们对此一直毫无方法。后来有人发明了臭豆腐，这才使豆腐剩余不会浪费。但大多食物很容易腐烂，所以一般剩余食物只能浪费掉。而后来，由于科学的发展，科学家发现了一种叫氟利昂的氟氯烃，无毒且稳定不易分解，最重要的是它可以制冷，于是电冰箱产生了。由于十分方便安全，所以冰箱很快传遍了千家万户。但让人们始料未及的是，氟利昴将严重破坏臭氧层，使紫外线射入地球。

不仅是氟利昴，回首以往，又有多少是科学带给我们生活的危害。当一座座化工厂拔地而起时，我们便再无法体会那“晴空一鹤排云上”的诗情；当一个个收割机开进田野时，我们便再无法领略那“采菊东篱下，悠然见南山”的闲适；当一桶桶废液排进江河时，我们便再无法感受那“野旷天低树，江清月近人”的情怀；当一柱柱废气飘然上空时，我们便再也看不到“天高云淡，望断南飞雁”的情景；当一管管化工污水流进小溪时，我们便再也无法感受那“小桥流水人家”的柔情；当一袋袋农药洒进果园时，我们便再也无法观看“梅子金黄杏子肥”的场面。

科学带来了我们太多太多，给了我们方便，而同时又带给了我们许多潜在而长久的危害。所以，若要社会发展，时代进步，则必要科学为先；若要生活美好，传世万代，则必须自然为首。《周易》曰：“亢龙有悔”，因此我们在发展科学同时，不滥用科学成果，以自然为首，调整好科学与生活的关系，让科学多带给我们些美好，少带给我们些危害，让我们的生活焕然一新，美好非凡！

这个节日的由来逝代中国有一位博学多闻的官吏屈原，他是一位爱民而且又受到尊崇的官吏，但是由於一位充满嫉妒的官吏陷害，从此在朝廷中被皇帝所冷落。由於无法获得皇帝的重视，屈原在忧郁的情况下投汨罗江自尽。

由於对屈原的爱戴，汨罗江畔的居民匆忙的划船在江内寻找屈原，并且将米丢入汨罗江中，以平息汨罗江中的蛟龙。即使他们当时并没有找到屈原，但是他们的行为，直到今天在端午节的时候，仍然被人们传颂纪念著。

The origin of this summer festival centers around a scholarly government official named Chu Yuan. He was a good and respected man，but because of the misdeeds of jealous rivals he eventually fell into disfavor in the emperors court.

Unable to regain the respect of the emperor，in his sorrow Chu Yuan threw himself into the Mi Low river. Because of their admiration for Chu Yuan， the local people living adjacent to the Mi Lo River rushed into their boats to search for him while throwing rice into the waters to appease the river dragons.

Although they were unable to find Chu Yuan，their efforts are still commemorated today during the Dragon Boat Festival.

Nowadays, many families have a dog or a cat as a pet. Some people think

that pets are good and helpful companies. Some of them even go so far as saying

that animals are as good as humans, and their rights should be respected .Senior

citizens are especially fond of keeping pet because they are always feeling

lonely at home and they see the cats or dogs as their partner.

But some other people do not like pets. They say that animals are noisy,

dirty and dangerous. They think laws should be made to forbid people from

keeping pets in cities and towns.

In my opinion, pets are loyal friends that will never betray us. Staying

with pets, we shall enjoy happiness and feel relaxed. Most important of all,

keeping pets helps people to reduce loneliness and forget their unpleasant

things for the time being.

university entrance exam in July this year. Everyday, I buried myself in

studying. I had to review each required subject and do lots of exercises.

exercises than other courses, which made me discouraged. I spent more than ten

hours a day in studying. When I was tired, I watched TV or listened to music for

a little while. But It was a big pity that I couldnt go to the see cinema. In

addition, I had to refuse all the invitations of friends and relatives. I only

called them or sent messages in the New Year’s Eve. I desperately hoped that

there is no exam but I know it’s impossible. The only thing I can do is to study

hard to get good scores and can be admitted to Tsinghua University.

[高中英语作文：旅行的真谛

According to the variety of social background, personal experience and

personal emotion, differernt people have different opinions towards things.

Thus, there is no doubt that generation gap exists everywhere. We always find

that there are big differences between us and the old generation. We always

regard the old are outdated, while they think us are crazy. They can’t bear the

dress we like, the fashion we pursue or even our childish thinking. Instead, we

could put up with their standpat thingking and their “feudal rulers”. Thus, the

generation gap becomes more and more obvious and serious. However, why don’t we

realize that opinions can be changed, while people can’t. So, we can think in an

other way, learn to accept. It is certain that we can narrow the generation gap

to live a more harmonious life.

Nowadays, more and more college students are addicted to online games. Those games may be funny and exciting, but are very harmful to those addicts.

In my opinion, there are many disadvantages of game addiction.Firstly, online games take up a lot of players time for study. Many of the addicts found themselves forced to drop out of school for poor academic performance. Secondly, addicts tend to isolate themselves from the reality. Whats worse , indulging in the virtual world for a long time, they are more liable to suffer mental problem and physical collapse. Thirdly , players are exposed to too much violent and unhealthy material, which is definitely harmful to their growth.

In short,I cannot see any benefits from online games.Study should be the primary concern of college students. Therefore,I do hope they can step away from online games.

Since we go to school, the teachers educate us to be a better person, they

tell us that we must study hard, so that we can be the useful person. Many

students confuse about what is the useful person. In my opinion, the useful

person must have the good merit.

A person with the kind heart is favored by everyone and he has the sense to

serve others. The bad person will bring danger to others, even to the society.

The most important thing of the useful person is to make a contribution to the

society.

They will make full use of their knowledge and be proud of serving for the

society. Our premier Zhou stated his purpose of learning knowledge was to make

our country rise. He did it and he became the great person. Becoming the useful

person is not easy, we should fight for it.

I havent write diaries for a period of time. I am now writing this just want to remember one thing. My study has fallen behind a lot this term.

I think I can be the best without studying hard. So I usually not pay too much attention on my study. When I find myself lag behind, I comfort myself it is accident. I have learnt a serious lesson this time. So, I want to write it down to warn myself.

我已经有一段时间没有写日记了。我现在写这篇日记只是想要记住一件事。这个学期我的学业落后了很多。我成绩之前可以保持在全校前十名。但这个学期我后退了。我差点就退到了五十名了。我知道原因是我太自大了。我觉得我不努力学习也可以保持最好。所以我一般都不怎么在意我的学习。当我发现自己落后时，我安慰自己只是意外。这一次我吸取了深刻的教训。所以，我想把它写下来以此警示着我。

I still remember the first time I went to the zoo.

When I was only five years old, my mother took me there.We took the camera and went to the station together. There were so many monkeys, tigers, lions, wolves and other animals in the zoo. We took many photos in the zoo with the animals. I was pleased to see so many real animals at the same time. They seemed so lovely and active.

I spent a nice day. But on my way home, I began to feel sorry for them. They were taken away from their parents and friends and also far away from the nature. They must have felt lonely, I thought. Every day, the only thing they could do was to sit there and wait for food.

我仍然记得第一次去动物园的那一天。

5岁那年，妈妈带我去动物园。我们带了相机一起过去。那里有猴子、老虎、狮子和狼等等，我们跟它们照了很多相。我很高兴能同时看见那么多活灵活现的动物，他们看上去又活泼又可爱。

我度过了快乐的一天。可是在我回家的路上，我开始替它们难过起来。人们把它们从父母和朋友身边捉走，它们一定感觉很孤单，我想。它们每天惟一可做的事就是等着人们来喂食。

the exam. But when I got home, the lunch was not ready yet. I felt unhappy. When

the dishes were served, I forund none I like. I ran out of my house angrily and

told me that it was my mother ther that had brought it here.After opening the

box, I found my favorite food inside. My eyes was moist with tears.

Mother gave me her love without asking for return, How deep mother love

今天，天气晴朗，秋高气爽。同学们一个个笑逐颜开，校园里到处都是欢声笑语，因为大家盼望已久的科技节终于开幕了。

走进教室，迎面扑来一股“科技风”，平日安静的教室此刻一片热闹的喧哗声。同学们有的在叽叽喳喳地交谈；有的在兴致勃勃地观看同桌带来的小物品；还有的在仔细整理科技书的封面。当老师进来宣布“图书漂流和环保义卖”活动开始时，大家都迫不及待地忙开了，有几个同学在教室门口摆起了地摊，还吆喝起来“瞧一瞧，看一看，亏本买卖，买二送一”有两三个同学在为一本科技书腼腆地讨价还价，你一言，我一语，最后各取所需，满意成交。真有趣，我转悠了一圈，发现物品还真丰富，有图书，有各种新奇的小玩具，还有同学们自己的手工小制作，真是琳琅满目，应有尽有。

三四节课时间是举行“科技节之自由快乐体验活动”。当我们来到操场，这里早成了欢乐的海洋。鲜艳的横幅，热闹的人群，丰富的活动项目。我们必须拿着老师预先发的小地图才不会迷失方向。我和同学在流动的人群中穿梭往返，东看看，西瞧瞧，这边排起了长队，原来是在调制泡泡液。只见有同学拿着自制的泡泡液，吹出了一串串五颜六色的泡泡，在阳光的折射下反射出耀眼的光芒。那边传来一阵欢呼声，我好不容易挤过去，原来是在做科学小实验“神奇的纸片”我也排队体验了一把，把一张纸片盖在一个装满水的容器里，再倒过来，瓶口朝下，不但纸片不掉，水也不会溢出来。“成功咯”我高兴地跳起来。操场上人山人海，还有各种有趣的活动等着我们排队参与。有“蓝白分营”，有“科技大蓬车”，真是令人目不暇接。其中最引人注目的是“鸡蛋撞地球”的活动。只见同学们先把鸡蛋全副武装，放在各自的“保护伞”里，再登上四楼，让鸡蛋从天而降，要保证它不会粉身碎骨。我赶忙跑过去看，有的鸡蛋因为保护得好，居然完好无损，真是太出乎意料了，看来还真得动一番脑筋呀。

下午，我们在教室里观看了精彩的电影。这次科技节，我和同学们都获益匪浅，不但学到了知识，开阔了眼界，感受到科技的发展，更让我们体验到了学习的快乐。
