Task： If the product is of good quality and meets people’s needs, people will buy it. Therefore, advertising is unnecessary and is no more than a type of entertainment. To what extent do you agree or disagree?
如果产品质量好，满足人们的需求，人们就会去买。因此，广告是没必要的，仅仅是一种娱乐。你在多大程度上同意或者不同意?
思路解析：
1. 娱乐功能：在指导人们购物上，广告的作用正在衰退。举例，人们更喜欢通过互联网的帖子和测评信息来选择商品。
2. 销售功能：广告帮助人们有效地了解和对比产品。举例，通过广告中对于相关产品的参数，功能，和总体性能的描述，客户能了解到该产品的特点和价值，并对于产品的好坏做出判断。
3. 刺激销售：广告能勾起观众的购买欲。举例，一个精美的广告往往能让用户重复购买他们不需要的东西，如奢侈品广告。

What is the root function of an advertisement in media? Some people believe it is just for entertaining viewers and it has nothing to do with products selling. Personally, I hold an opposed view that advertising is still the main way of stimulating the consumption of common goods, and my reasons will be explored as below.
Admittedly, Advertisements today have less influence on the public to purchase commodities, because now there are diverse information accesses to understand a product. For example, on an age of Internet, people with desires of purchasing goods, especially the youngsters, prefer reading the professional articles of forums or assessment websites collecting comments and feedbacks from consumers, or listening to the advices from the face-to-face communication with friends and peers. In their eyes, the description of a certain product on an advertisement is unpractical, unobjective and unconvincing. Therefore, advertisements—such as posters in billboards and Videos in TV screens—are viewed as the amusement by which the audience’s stress and worries in minds can be relieved.
However, I strongly believe this assertion underestimate advertisement functions in day-to-day life. Firstly, by what way can a customer be sure of whether a product is really good or needed? The answer is definitely the advertisement. For example, today cell phones of different bands have a high similarity in their appearances and shapes, and it is a big challenge for customers to pick put the right one. So there is a necessity for adverting, which can clearly presents the inner components, parameters and unique features of a cell phone. By reading the detailed information, customers can easily distinguish one product from others, and make a proper judgment of which one is the best or most satisfying for them.
The second reason against this assertion is that advertisements can encourage viewers to buy items they do not need. For example, typical slogans on advertisements like “special discount”, “limited time offer” and “buy one get one free”, are overwhelming temptations. They manipulate brains of customers, driving them to purchase these bargains, with no concern of whether the products are really essential or not.
All in all, this assertion is basically problematic. Although the influence of advertisements is declining, they are still irreplaceable, in terms of their great contributions on instructing people to compare and select high-quality products, as well as sparking the desire of customers to do more shopping.
