阅读理解。 There are thousands of things to be sold that are of all colors and shapes in a supermarket, making you believe that they are good enough for you to have a try. How? Packaging (包装) is the quiet but persuading (有说服力的) salesman. There on the shelves, each bottle, can and box has been carefully designed to speak to the inner self of the consumer (消费者), so that he is buying not only a product (产品) but also his belief in life. Scientists have studied on this and found that the look of the package has a great influence (影响) on the 'quality' of the product and on how well it sells, became 'Consumers generally cannot tell between a product and its package. Many products are packages and many packages are products,' as Louis Cheskin, the first social scientist studying consumers' feeling for packaging, noticed. Colors are one of the best tools in packaging. Studies of eye movement have shown that colors draw human attention quickly. Take V8 for example. For many years,the bright red color of tomatoes and carrots on the thin bottle makes you feel that it's very good for your body. And the word 'green' today can keep food prices going up. Shapes are another attraction．Circles often mean happiness, because they are pleasing to both the eye and the heart. That's why the round yellow M sings of McDonald's are inviting to both young and old. This new consumer response (反应) to the colors and shapes of packages reminds (提醒) producers and sellers that people buy to meet the needs of both body and heart. 1.
