Movie makers often make use of visual illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of visual illusions.

If you open today’s newspaper, what do you see? Ads! Look through a magazine. More ads! Turn on the TV. Still more ads! Everywhere you look, someone has something to sell.

      Here are some ways ads get us to buy. Some ads use famous people. Stars are paid to sell a product. Think about it. Do they really know about medicine? Do they know about soft drinks? There people may be famous, but they may not know about what they are selling.

      Some ads make you think you’re getting the word of an expert. They say, “Doctor said.” A man in a white coat comes on TV. He looks nice. “I use Bright and White,” he says. This man looks like a doctor. But he is an actor. He has been paid to sell this product.

      Does soap have anything to do with a pretty child? But ads may show their product with something nice, such as the sun, the flowers and so on. Such an ad is about feelings rather than facts. Ads are full of strong words. Words like “new” and “improved” have strong influence. They can help a product sell. The soap may be called “Spring Rain”. A car may be called “Tiger”. Strong words work on our feelings.

      Some ads make promises（承诺）. But can they keep them? No. Some ads use our fear of being too late. “Buy now!” they say. “Selling ends soon.” Check to see if this is true. Don’t hurry. Take time to think. All ads hope we will buy something, do something, or think in a certain way. Know what ads are doing. Ask questions to yourself. Don’t let their words and pictures fool you.
