　　Some people believe commodities that are popular among consumers reflect the power of advertisement rather than the real needs of people. Do you agree or disagree?
　　Whether we like it or not, advertisement has been pouring into our daily life. They are so powerful that some people believe that it is not the needs of people but the power advertisement that makes commodities popular. Personally I don't agree with this opinion.
　　First, let's make clear what the real needs of people are. Real needs can be divided into two categories: the material satisfaction and spiritual satisfaction. People tend to regard material satisfaction as real needs and spiritual satisfaction as waste of money and time. This is not true. Some commodities may not be useful but they can give the owner a kind of satisfaction.
　　Second, let's make clear the reason why advertisement is powerful. The key principle of advertisers is to grasp the needs of consumers, then pass the potential consumers the information that their commodities can meet your need. Advertisers can promote the needs of people, exploit the needs or even produce the needs of people. But whatever they do, it will be based on the needs of people.
　　But there are some advertisements that exaggerate the functions of the commodities to tell the wrong information to consumers. They make the commodities popular by cheating the majority of consumers. And also there are some commodities that do harm to the health of consumers and to the society. For example, smoking is poisonous, but the advertisements try to make a heroic image of the smokers, as the result smoking is popular among young men who are dreaming to become heroes in women's eyes. But such advertisements are minorities.
　　In summary, advertisements bring us convenience to choose the commodities that can meet our needs. Most of the commodities are popular due to their usefulness, only some of them are due to the influence of advertisement. (298 words)
