电脑--未来的主宰 600字高中英语作文

　　二百多年前，蒸汽机的发明，轰隆隆地把人类带进了工业化社会；一百多年前，电灯的出现，呈现给人类一个五彩斑斓的电气化世界；六十年前，电脑的产生，把人类带上了高速发展的轨道，地球成了一个村落。电脑正逐步成为人类生产和生活的主宰。

　　电脑的运用极高地提升了生产效率。从宇宙飞船发射到纳米技术的研究，从核弹爆炸到流水线生产，人类生产的方方面面无不因电脑的运用而提升了生产效率。美国阿拉莫斯国家实验室一台几个篮球场大的一台电脑，能用于模拟核试验，它一秒钟能运算数百亿次，几天就能干完人类自己永远也干不完的工作。即使在普通行业，电脑也起着重要作用。比如在教育领域，一个老师想要统计一个年级某次考试的成绩，算一下平均分，用电脑，几秒钟就行了，如果用手工计算，则要几小时。

　　电脑及以电脑为载体的互联网，促进经济快速增长。互联网使人们获取信息更为方便快捷，从而使投资、生产、销售等环节的速度加快，这样有利于经济的迅速发展。美国前总统克林顿1992年提出旨在提高互联网信息传递速度的“信息高速公路”计划，使美国的经济持续数年稳定快速增长。

　　电脑还日益影响着人类的生活方式。互联网的出现消除了地域差距，使天南地北的人可以聚在一起谈心，足不出户，畅游世界。千里之外打扫房间等天方夜谭式的想法也已经在电脑的帮助下实现。

　　当然，电脑有许多好处的同时，也有不少隐患。于是有人认为电脑弊大于利，阻碍了社会的发展。这种看法当然是错的。电脑尤其是互联网出现的时间还很短，完善和发展还需要很长时间。况且每一种事物都不可能只有忧点没有缺点。核能能给人类巨大能源，同时又在人类头上笼罩着核爆炸的阴影；克隆是人类科学的突破，但克隆人却有悖人类伦理道德。

　　电脑及互联网的地位日益重要，我们应该怎么做呢？有调查表明，泱泱大国俄罗斯的互联网用户只有三百多万，这让我们更深刻地了解了她衰落的原因。事实证明，电脑和互联网的不普及导致信息的闭塞，信息闭塞导致生产落后，生产落后导致国力落后。经济刚刚起飞的中国如果不想再次落后，就必须重视电脑和互联网的普及。可喜的是，我国已经拥有“联想”、“方正”、“新浪”、“搜狐”等自己的电脑公司和网络公司，虽然离自己自主开发还很远。

　　电脑和互联网的旋风刮起来了，你准备好了吗？

我爱我的家乡英语

　　Everyone has his own hometown， so do I。 Do you want to know my hometown? Let me tell you something about it。

　　I was born in Shicun Town。 It lies in the north of Guangrao。 It’s about 10 kilometers from Guangrao county。 Although there are not high mountains or long rivers， there are friendly and hard-working people like my parents， there are my good friends that have played and studied with me since we were young children。 So I still think it is the most beautiful and I love it very much。

　　Many years ago， people lived in low and small houses， they wore shabby clothes and ate simple food。 They didn’t have computers or TV sets。 I can’t imagine what they did for fun。 They didn’t have cars， buses， motorbikes， even bikes。 When they went out， they could only be on foot。 In a word， their life was poor and simple。 But now， great changes have taken place in my hometown。 Thanks to the good policy of the Party， people are getting richer and richer。 They build wide and bright houses， they wear new and modern clothes。 They can not only get enough food， but also delicious and healthy food。 Now they have different kinds of digital tools for fun， such as mobile phones， TV sets and computers。 They can use them to relax themselves after work。 When they want to go to some places， they can go there by bike， bus， car， even train and plane。 They can travel around our country to see beautiful scenery in any way。 I am proud to say that my hometown is getting better and better!

　　Many years ago， there were few factories。 The sky was blue， the river was clear and clean， and there were some different kinds of fishes， there were many green trees and beautiful flowers on both sides of the road。 But with the development of the industry， the environment around us is getting worse and worse。 Many trees are cut down to build more factories。 The sky is not so blue as before， water in the rivers is getting dirtier and dirtier， fishes are fewer than before。 Some factories even make the air terrible。 It is bad for our health。 I am sorry to say that the pollution in my hometown is getting bad。 But luckily people have already realized that it is important to protect our environment。 Many things have been done for that。

　　As a member of my hometown， it is our duty to build and protect our hometown， we should act quickly。 We should call on people not to pour the dirty water into the river or make the air terrible。 Everyone should care for our living environment。 We should plant more trees and flowers to make our hometown more and more beautiful。 As a student， I must study very hard to get more knowledge。 When I grow up， I will try my best to build my hometown。 I am sure my hometown will be better and better! Do you think so?

　　My speech is over。 Thank you!
