雅思口试题目：为什么广告能有效影响人们的购买决策？Why does advertising have such a powerful influence on what people buy? 提供信息，帮助顾客了解产品。

Advertising is a very powerful tool and it's getting more and more popular these days. I think many people don't have any real knowledge about a product, so most of the time they rely on advertising for information, which they think is trustworthy. If there is no advertising, consumers will not realize certain products exist so they will not buy it. If you advertise your customers are introduced to your productsand may be encouraged to make purchases.

广告作为一个强有力的宣传工具正获得日益广泛的关注。很多消费者对产品并不了解，就会依赖于广告，并认为其中的信息是真实的。如果没有广告，消费者就意识不到产品的存在，当然也就不会购买。如果为产品做了广告，消费者就有可能被吸引并购买。
