The Internet is an amazing invention.Because of its getting into almost everyone's life，the world will probably never be the same.
   People can log onto（登錄）the Internet in search of whatever they need.An elderly woman who is unable to drive can log onto the Internet and shop for goods，and even chat with her grandchildren without leaving the house.Collectors no longer have to go to flea markets or yard sales on weekends to find used things to add to their collections.All they have to do is log onto Ebay and post a bid.Anything can be bought online now.
   As a teacher，I have found the Internet is useful in preparing the teaching plans.The Web has many sites created for teachers to share ideas，exchange information，and share documents.Perhaps young people can get the most from using the Internet.Besides，they can also use the Internet for school projects and homework.Being able to express themselves on sites like MySpace and Twitter is another big advantage of using the Internet.
   As a saying goes， "Every coin has two sides." I think students sometimes depend too much on the Internet.They don't seem to understand that just being on Google doesn't make it a trusted source.I cannot count the number of times a student has turned in a paper that contains incorrect facts from sites.
   What's worse，chat rooms have become the new playground for bad guys.The Internet gives them the anonymity（匿名）they need to draw the attention of children and lead them to improper conversations.Children may also find some sites are improper for them.Even adults can fall prey to（受害）identity theft and stolen passwords（密碼） if they aren't careful about the things they are downloading onto their computers.
