Internet最早来源于美国国防部高级研究计划局的前身ARPA建立的ARPAnet,该网于1969年投入使用。起初它只是用于军事,随后,通过“互联网之父”约瑟夫等人的改进,互联网不断地进入我们的生活中,使我们的生活变得多姿多彩。
互联网使信息浏览更加快,更加方便。如果在1990年,想查一下关于美国各方面的资料,我们要到图书馆或者是打个长途电话去问美国的亲友。现在不同啦,有了互联网,用鼠标轻轻一点,就可以查到关于“美国”的各种资料,不用十秒钟。
互联网使人与人之间的沟通更近、更快。古代,住在东莞的你想写信给北京的亲友,那就要把信攀山涉水用马送过去,少则一个月,多则一年;在近代,你可以打长途电话,但是价格不菲,也不能传送文件或者图片;现在,有了Internet,我们可以通过QQ、E-mail等方式跟远方的.亲友沟通,跟美国的客户联系,聊一个小时不过是花费1元左右,而且还能用视频电话,人与人之间的距离就变得越来越近了。
但是,互联网也有很多不好的地方,它摇身一变,就变成了犯罪分子最好的武器。
犯罪分子利用互联网这个虚拟而又辽阔的世界,进行犯罪活动。他们披着互联网的保护衣,使人们看不见他们丑恶的心灵。经常有报纸报导“一位女子因上QQ受骗在XX被***”,这就是铁一般的事实。另外,还有很多“黑客”,他们到处散播病毒,使互联网的速度大大减低,严重阻塞互联网这条高速公路。更可恶的是一些不法网站竟然在网上提供色情、暴力等图片、文字,严重毒害着人们的心灵。
当今社会中,互联网为我们提供了一片无限广阔的土地,在这片土地上生长的各位网友,不要使这片土地荒废,用它来耕耘出丰硕的果实吧!
Time flies like an arrow before we realize it .It is known that nothing is more precious than time. The good old proverb "time is money" reminds us that time is valuable. When time goes by, it will never return. However, it is a pity that some people don't make full use of their time .They spend a lot of time in sleeping, chatting playing computer games or other unmeaning matters. . They don't realize that wasting time is actually equal to killing themselves. They always regret not having made great achievements. One of the reasons may be they do not make good use of time. Therefore, in order to be successful, they should first get into the habit of being on time. It’s a sign of cherishing time. Don't put off what can be done today until tomorrow. Being lazy will eventually lead to failure. Don't wait, because you don't know how long it will take when you put off your plan.
The more we are aware of the significance of this famous saying, the more benefits we will get in study or job.
