1. 根据短文内容，选择正确答案。

    More and more advertisements appear on the Web. You have to be careful, or the advertisements on the Internet will fool or trick you. They say something is a bargain, but it isn't always cheap. And some so-called (所谓的）new things just have a new outside.

However, shopping online is a kind of fashionable thing today. I love to buy things of everyday use, so I often get lots of information about them on websites online. For example, if I want an MP4, I can choose my favourite one, and look for what the users like or don't like about it, then decide whether to buy or not. And at the same time, you don't have to go to a shop or walk around 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.
