1. 現在有些不良的商業廣告
2. 這些廣告的副作用和危害性
3. 我對這些廣告的態度
Nowadays ther are a lot of false advertisements in society. They have caused many harms to society. Generally, their harms can be listed as follows.
First, they exaggerate誇大 the functions of the goods they advertise and mislead consumers. Second , some advertisements contain obscene淫穢的 contents and bring about spiritual精神上的 pollution. Third, they seriously damage the credit of businesses because the shops which sell those goods will be distrusted and even considered the conspirators同謀者 of those advertisers by consumers.
Personally, I am usually vigilant against any advertisements and so I have never been taken in. However, some people are credulous and are easily taken in. Therefore, in my opinion, effective measures must be taken to ban false advertisements and protect consumers' interests. First, all the advertisements must be strictly censored by the authorities concerned before they are published. Besides, severe punishment must be inflicted on those who publish illegal advertisements.
In conclusion, false advertisements must be eliminated清除，消除 in our society.
