英语作文：Do ads play a negative or positive part in ous life?

答案

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.
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.
