Advertising
Advertising is a very big business these days. Billions of dollars are spent every year to persuade customers to buy one brand of product rather than another. We are all exposed to such advertisements every day and their effect on us cannot be denied. While it is true that some advertisements do provide useful information about new products， I believe that their primary effect is to encourage people to buy things that they don't really need. First of all， most advertising does not introduce a brand-new product. Instead， it is designed to persuade consumers that one company's product is superior to that of another company. Second， when a product is new， the advertising is often designed to create demand for it. In other words， its goal is to convince potential buyers that this new product is really necessary， whether or not it actually is. Third， many advertisements are image ads， designed to sell people luxury products. The ads imply that by buying such products the consumer will gain something else such as happiness， respect or love. These ads not only try to sell things that people do not really need， but promise something that cannot be bought. Finally， if there is new information about a product or development， people will hear about it through word of mouth， and in my opinion， this is a more reliable source of information. While it can be argued that advertising is sometimes useful to consumers who may want to compare different brands， I believe its overall effect is to get people to buy things that they don't need. That is not to say that the advertisements are deceptive. They are simply designed to create a need for the product among consumers. Therefore， we should all look at advertisements with a critical eye in order to avoid buying things that are not necessary.

广告
广告业如今已成为非常大的产业。每年花在广告上的经费有好几十亿美元，以说服顾客买某个品牌的产品而不买别的家的。我们每天都接触这一类广告，它们对我们的影响是不可否认的。虽然某些广告的确提供了关于新产品的有用资讯，但我认为，它们的主要功用就是鼓励大家去买一些不是真的很需要的东西。
首先，大多数的广告并不会介绍一个全心的产品。相反，广告设计的用意是要说服消费者某家公司的产品比另一家好。其次，当推出一项新产品时，广告的目的常是制造对这项产品真的是必需品，无论是否真的如此。第三，很多广告都是形象广告，目的是要将奢侈品销售给大家。这种广告会暗示，买了此类产品的消费者会得到其他的东西，如快乐、尊敬或爱。这些广告不只会试着销售一些人们并不是真的需要的东西，而且也会保证你得到某样买不到的东西。最后，如果有与产品或开发相关的新资讯，人们会口耳相传。我认为，这才是比较可靠的资讯。
虽然友人认为广告有时能够帮助那些想要比较不同品牌产品的消费者，但我认为，广告整体的效果就是要人们购买自己不需要的东西。这并不是说广告都是骗人的。它们的目的只是要让消费者对这项产品产生需求。因此，我们都应该用批判性的眼光来看待广告，以免买到不需要的东西。
