提示词：cheat 上当, 受骗
In the modern world, advertising is everywhere! Some people like ads and others hate ads. I think it offers some advantages and disadvantages.
Some ads are very useful. They can tell people how to compare two different products so that people can buy the better one. They can also help you save money.
However there are also some disadvantages. Some ads can be confusing or misleading. Sometimes the words sound good but don’t tell you anything real. So you have to be careful not to be cheated. We shouldn’t believe everything.
