【问3】我在剑六的Writing Test 1的Task 2部分看到一篇Band 7.5的范文，书中仅有考官的简单评语，但我不知道文中究竟有那些错误。请您能否予以修正和讲解，并改写成一篇标准的范文？谢谢。

题目和范文如下：Today, the high sales of popular consumer goods reflect the power of advertising and not the real needs of the society in which they are sold. To what extent do you agree or disagree?

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 arguments may be true. In my country, many advertising companies produce advertisements with famous and popular actors or singers. People, especially youngsters, buy goods that their favourite singer advertise, although they do not really need the products.
