【正确答案】[范文]
   Nowadays, there are lots of advertisements on television or on the streets. Some people think that the advertising boosts the sales of goods and it encourages people to buy things unnecessarily. This argument may be true. Around the world, many advertising companies produce advertisements with famous and popular actors or singers. People, especially youngsters, buy goods that their favourite idols advertise, even if they do not really need the products.
   For one thing, on the television screen a product may look gorgeous and be of solid quality. As a result of this, people often buy goods without enough consideration. Consumers may not actually need them but they buy goods impulsively soon after they watch the advertisement. Furthermore, as many customers buy a particular product due to its advertising campaign, other people may be affected by the trend, even if the product is not essential to society.
   On the other hand, there are various aspects against this argument. In particular, it is the people's choice to make a decision to buy goods. Advertising may not even be a major cause of customers' buying activities as individuals have their own spending habits. If they have got enough disposable income, then the right to make a decision is given to them. No one can actually judge whether the goods sold are really necessities for society or not. In addition, as there tends to be a limited amount of disposable income consumers are able to spend, people try to allocate their budgets. They cannot be swayed simply by those advertisements.
   In conclusion, as customers have their own strong opinions and standards of high quality products, it is better to leave them to make their own decisions in buying goods. It is implausible to claim that everyone is swayed by advertising and buy goods impulsively.
