       More and more advertisements appear on the Web. You have to be careful not to be fooled or ticked

by the advertisements on the Internet. Something is said to be a bargain. but it isn't always cheap. And

some so-called new things just have a new outside.

       However, shopping online is a kind of fashionable thing today. I love to buy things of daily use, so I

often get lots of information about them on websites online. For example, if I want an MP3, I can choose

my favorite one, and look for what the users like best, then decide whether to buy it or not. And at the

same time, you don't have to go to a shop or walk around in a crowded shopping area, so you don't have

to waste much time. The Internet is really useful for shopping, but be careful not to spend too much.
