背景句：Some people argue that it is pointless to spend money on the protection of wild animals because we humans have no need for them.
个人立场：I completely disagree with this point of view.
主题句：Through advertising we learn about new products.
论证：For example, many grocery stores now sell pre-packaged lunches. These are very convenient for busy parents. They can give these lunches to their children to take to school. Busy parents don’t have time to look at every item on the store shelf, so without advertising they might not know about such a convenient new product.
主题句：Even products we are familiar with may be improved, and advertising lets us know about this.
论证：Most people use cell phones, but new types of cell phone service become available all the time. There are different plans that give you more hours to talk on the phone, you can send text messages and photos, and next week probably some even newer type of service will be available. By watching advertisements on TV it is easy to find out about new improvements to all kinds of products.

主题句：Advertisements keep us informed about prices.
论证：Prices change all the time, but everyone can look at the ads in the newspaper and see what the latest prices are. Advertisements also inform us about sales. In fact, some people buy the newspaper only in order to check the prices and plan their weekly shopping.
