题目：The Internet has dramatically altered our lives over the past few decades. Although some of these changes have been negative, the overall effect of this technology has been positive. What are your opinions on this?
The Internet has brought significant changes to our lives in recent years. However, there remains some disagreement as to whether the overall effect of this technology has been positive or negative. While there are certainly valid arguments to the contrary, I personally believe that the benefits of the Internet far outweigh its drawbacks and these benefits are twofold.
First of all, it is an indisputable fact that the Internet has revolutionized the way we communicate. Despite the risk of social isolation-a problem occasionally seen in people who spend too much time at their computer terminal rather than relating to people in the real world-most of us have benefited greatly from e-mails and Internet chat programs like MSN Messenger. These incredibly useful and powerful tools of communication facilitate both contact with loved ones in faraway places and global trade.
Moreover, the Internet has placed the entire world (and all of the information in it) at our fingertips. In earlier times, conducting research entailed long hours searching library shelves. Now, however, the same information can be accessed at the click of a button. Admittedly, not all of the information available on the Internet is reliable or helpful-there is a vast amount of material online that some would consider offensive or dangerous, ranging from pornography to instructions on how to make bombs. Nonetheless, I would contend that this free flow of information has generally been a very positive development.
By way of conclusion, I once again reaffirm my position that the Internet has had a positive impact on modern life because of its influences on communication and the flow of information.
