Save the Wild Animals

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.

In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.

Only if we human beings take some drastic measures can wild animals be preserved.

保护野生动物

许多野生动物正面临绝种的危险，因为它们生活的环境发生了极大的变化。譬 如，随着城市的发展，杀虫剂的使用和严重的污染，野生动物的生活区域变得越来越狭小。许多野生动物目前正面临着食物方面的危机。同时，为了获取野生动物的毛、皮、角、牙齿和肉，人类正在屠杀野生动物。

为了保护生态资源，人们应当意识到任何物种的缺失，至少意味着知识资源和自然美的缺失。因此，应采取以下措施：制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动植物保护区。

我们只有采取一些有力措施，才能保护野生动物。

had been cracked and the screen had been scratched.

In view of this, I have decided to make a formal complaint against your

delivery service. I sincerely hope that you will replace this computer as soon

as possible. If this is not possible, I will have no alternative but to insist

on a full refund.

I would appreciate anything you can do to help us in this matter.

Yours truly,

In recent years, the forests have been getting smaller and smaller for more

and more people cut down trees for money. As trees grow naturally, people dont

need to invest anything on them. But cutting down trees has destroyed our

nature. We have already seen the bad consequence. For example, we always suffer

from the flood and drought disaster; many animals are facing the danger of dying

out, because their habitats have been destroyed; deserts are expanding, and

sandstorms are emerging. Our environment has been changed from bad to worse due

to the reduction of forests. Thus, the government should appeal people that

cutting down trees breaks the balance of our nature. Those who continue to cut

down trees should be punished severely.

I think reading is important in the whole life for people. There are many

benefits of reading.

Firstly, reading increases our knowledge and we can learn the world affairs

without going out. Secondly, reading is a good way to improve reading and

writing skills. Before you learn to write, you must know how others write.

Thirdly, reading can broaden our knowledge and horizon, which is important to

job hunting in the future.

Finally, reading helps us become self-cultivation that would be beneficial

to our whole life. Therefore, start to reading, no matter how old you are and

what you are doing. Then, you may find the great charm and benefits of

reading.

Earthquake is one of the most severe natural disasters. Its shaking of the

ground caused by the sudden breaking and shifting of large sections of Earths

rocky ourter shell. Its results can be very horrible. The Wenchuan Earthquake in

2008 and Japan Earthquake in 2011 are the most severe earthquakes in recent

years, causing huge casualties and property losses. But earthquakes almost never

kill people directly. Many deaths and injuries in earthquaking result from

falling objects and the collapse of buildings

We talked about the advantages and disadvantages of internet shopping these days. Some students think its very convenient for us to go shopping on the internet. The shops on Internet ，for example taobao.com, 360buy.com are open for almost 24 hours a day, so we can buy something we want at any time if we like. Whats more, we neednt to wait in a queue.

However, some students disagreed with them. We cant see the things while we are shopping. So we are not sure whether they are good or not.. Besides, we cant enjoy the happiness of shopping with our friends.

抗击疫情

在2020年的伊始，新型冠状病毒悄然闯入我们的世界。这是一场无硝烟的战争，也是一场全民参与的战争。

随着疫情的发展，人们也意识到了这次疫情的严重性。逐渐地，以武汉为首的封城封村向外扩散，这个行动可以隔离病毒，却不能隔离爱。

面对突发的疫情，逐渐恶化的形势，各地医疗队伍纷纷奔赴武汉。他们身上背负着国家的期望，人民的希望。所谓的英雄，就是平凡的人做出了不平凡的选择。

向白衣天使致敬。相信我们团结起来，共同行动，一定能够战胜疫情!

There is nothing more important in life than the sun .Without the sun all

living things on Earth would die. The sun is a star .In the sky there are

thousands of star like the sun .They are as large as the sun and as hot as the

sun .At night you can see many stars, but in day-time you can only see one star

---the sun.

The sun is much nearer to us than any other star.That is why it books like

the biggest and brightest of all the stars .The distance of the sun from the

Earth is as much as 150 million kilometres .Most of the stars are thousands of

light years away from the Earth .

Do you know what a light year is ?Nothing in the world travels faster than

light .It travels 300,000 kilometers a second .One light year is the distance

that light travels in one year .

中秋节是中国一个很重要的节日，在八月十五号。在节日来临的前几天，家庭中的每一个人都帮着打扫房子，把房子装扮得漂漂亮亮的，灯笼挂在屋前。

晚上有一顿美餐，离家在外工作的人也要回来团圆。晚饭后，人们点亮灯笼，一般是红色的圆灯笼。孩子们会高高兴兴地玩他们的玩具灯笼。

晚上月亮又圆又大，人们在赏月的同时吃着中秋节特别的食品——月饼。人们在一起回顾过去，展望未来。据说天上有一条龙，它要把月亮吞下去。为了保护月亮，孩子们要弄出很大的响动把龙吓跑。

现代科学技术正以前所未有的速度改变着世界的面貌，影响着人们的生活。丰足的衣、食，舒适的住、行，千百年来一直是人类最基本的追求。现代科学技术的发展，使人们的愿望逐步变成现实，让人们的生活跳动科技的音符。

寿命变“长”了

1900年全世界人均寿命仅为45岁，而今天这一数字正提高到66岁。联合国人口署已经把老年人的年龄界限定在“85岁以上”。人类寿命的大幅度延长，得益于20世纪医学的迅猛发展和生活水平的显著提高。

婴儿出生不久就要被接种卡介苗，1921年起进行人体试种的这种疫苗，消除了结核病的阴影。青霉素、乙肝疫苗、心脏起搏器、避孕药、器官移植、人造器官、显微外科、心电检测、超声波诊断、核磁共振诊断、断层扫描成像(CT)……这些今天看来很平常的发明和技术都是20世纪的重大医学成就。我国科学家在上海试验的转基因牛、羊，使人类看到了“动物药厂”的曙光。试管婴儿，克隆羊的问世，使人类生命之火越燃越旺。

在人类获得基因组的全部序列后，人类遗传密码的破译将进入全新的信息提取阶段。重大疾病基因将被发现，一些危害生命的疾病将会有希望治愈。

世界变“小”了

21世纪，信息技术将会从微电子向高集成度、低功耗、低成本方向发展，计算机向超高速、小型化、并行处理、智能化方向发展，通信技术向光纤化、数字化、综合化、网络化方向发展。信息技术的发展，将从根本上改变人类从事商务活动、交流、娱乐、学习，甚至工作的基本方式。

科技的发展使人类突破时空的约束，地球成了人类的村落。从公路到铁路，从水运到空运，运输工作的进步彻底变革了人们的出行方式。1903年，莱特兄弟用木头、电线、布料制作的飞机实现了首次飞行。飞行时间虽然只有短短12秒，却是一次划时代的事件。今天，日新月异的飞机制造技术，已可以使人们在24小时之内飞到地球的任何一个角落。

在过去一百多年里，无线电、网络技术等的发展，使信息插上了光速的翅膀。从电话到电报，从收音机到电视机，从移动通信到传真机，犹如中国古代传说中的“千里眼”和“顺风耳”，使人类之间的交流与沟通更为方便。你坐在家里的电脑前轻点鼠标，远在万里之遥的友人，便可以在瞬间收到你发去的电子贺卡。在昔日李自成屯兵养马的陕西商洛山区，如今农民已经通过互联网把生意做到了全世界。

人类在突破空间约束的同时，也开始突破时间的约束。录音机、摄像机、录像机、激光唱机和数字音像设备的发明，使得我们可以把自己的音容笑貌留给后代，我们也可以耳闻目睹先辈们的风采。

劳动变“轻”了

科技解放了全人类，迅猛发展的科学技术将越来越多的人从繁重的体力劳动中解放出来。

电子计算机是20世纪最伟大的发明之一。从人脑的计算到电脑的计算，人类创造了“人脑创造电脑，电脑促进人脑”的奇迹。在第一台电脑投入运行后的10年间，它的运算量估计比有史以来人为大脑所有运算量的总和还要多。现在，计算机汉字输入问题已经得到根本解决，无数中国人可以使用汉字在计算机和互联网上自由驰骋。

科技对社会和经济发展的巨大贡献日益证明，科学技术是第一生产力。据估计，以科技为核心的知识对经济增长的贡献率20世纪初为5%～20%，而目前这一比例在一些发达国家已上升到80%左右。

Cell phones have become increasingly popular in china these days. wherever

you go you can see people using cell phones. many college students, even high

school students, have cell phones.

Cell phones have brought people a lot of benefits, but the most important

is that they are convenient. with cell phones in their hands, they can keep in

touch with anybody they want. if they want to get some information from the

internet, they can easily have their dream realized via cell phones too.

furthermore, if someone has a heart attack or a traffic accident, a call to

emergency hospital or to the police can quickly bring him the help he wants.

However, cell phones can also bring people problems. the most serious is

the electric wave radiation which is thought to be harmful to users brains.

another problem is that when people are having a meeting or having a class or at

a concert etc, the ring of the cell phone may interrupt others. so i think

people should use cellphones as little as possible and turn them off when they

are attending important meetings or attending classes.
