internet: a blessing or a curse?
sifting through the history of the 20th century, i'm fascinated by a treasure trove of beneficial and innovative breakthroughs in science and technology. in the past century, numerous creatire inventions have been brought to us, leading to desirable transformations and speeding up the evolution of human civilization. the diverse technological developments improve the productivity and entitle us to a more favorable life. and among all those ingenious designs, the advent of the internet, i suppose,has the most profound significance to us mankind.
since the very date the internet came into being, it has changed our life and work dramatically. the world wide web reveals a magical and intriguing new world to everyone woven up into the net. the various websites provide a wealth of information and data for the 'netizens'. with their assistance, we needn't bother to plunge into multitudes of books in the library,searching for only one or two items. the powerful search engines, such as google, yahoo, and sina function as handy tools for us to find all we need, with just a few clicks. the variety of webpages supply updated news and informative knowledge, enabling us to keep abreast with the times. the bbs, short for the bulletin board service as a helpful medium for people to exchange available information. to us students on campus, the bbs means convenient connection with all our peers and easy access to useful messages. so in this sense, the internet has greatly enriched our life and promoted mutual understanding between individuals. moreover, the internet offers us instant communication with our friends and family no matter how far we are from each other. the emails, oicq,e-cards, net meetings and the emerging sms on the web all prove to be of sufficient help with this function. what's more, the internet begins to playa vitally important role in business and trade. the brand new e commerce such as b2b and b2c make it possible for the corporations to deal with their operations effectively and efficiently. and to the ipos (initial operation offering), the net acts as an attractive plat form for the road show.
however, does the internet only mean blessing to the human beings? definitely not. the fact is that plenty of negative influences have been caused by the net. the notorious hackers attack the websites of government and institutions rampantly,damaging their systems and interrupting the operations. in cyberspace, criminals easily commit crime and escape. and the computer viruses spread even faster through emails, causing lots of computer failures.
thus it's apparent that the internet is a blend of blessing and curse. but despite its disadvantages and shortcomings, i'm still in strong favor of the internet and i'd prefer to glorify its beneficial outcomes. adventurous as it may appear to be, it's undoubtedly one of the mellow fruits of human wisdom, right?

简 评
本文的主题是网络的福与祸。作者列举了网络对生活和工作尤其是商务的巨大影响，并具体、形象地描述了种种便利，颇具说服力。另一方面，作者也客观地阐明网络存在的问题，诸如黑客、病毒和网络犯罪。在文章的最后作者得出结论：网络兼有利弊，但
其主流是造福人类。
本篇文章不似出自学生之手。因为作者对网络这一新生事物的把握可谓运筹帷幄。最能体现作者对主题的专业水准的是大量、准确地运用专业术语。文中出现了一系列的缩略语如“www，bbs，oicq，sms，b2b，b2c，ipo'’以及网络相关术语如“netlzen，data，website，webpage，net-meeting，e-com-merce，e-card，platform，cyberspace，hacker，virus~’。这些无不显示出作者在此专题方面扎实的功底。
另外，文章的篇章结构和主题的推进可谓“有法但无定法”。本文显然采用了对比法。在证明网络的便捷时，作者把网络协助下的学习研究与传统的方式进行了鲜明的对比。一方面是网络上“a wealth of information，witha few clicks'’，另一方面是'plunge into the library for hours，searching only one or two items'，拥有网络的轻松和传统方式的麻烦形成比照。
