Are you familiar with large supermarkets? If so, then you probably know that almost everything in the market is in a container. Most food is in containers. Even fresh meat is sold in plastic packages. Fresh fruit and vegetables are usually the only food items that don’t come in containers. In fact, almost everything at the supermarket is in a bag, a box, a bottle, a jar, a carton, or a can.
    This kind of packaging system is necessary at large supermarkets. Supermarkets buy large quantities of everything. Products must be protected during shipment and they must sit on shelves for long periods of time. Containers, therefore, protect the products. Containers have another function, too. They give information about each product—names, weights, materials, and ingredients, and sometimes pictures of the products. This information is printed on labels or directly on the containers.
    But think of this, we never see most of the things we buy at the supermarket until we get home and open the containers. When we go shopping, we look at the labels on the containers. If the container is made of glass or clear plastic, perhaps we could see a little bit of the product. But usually containers completely hide their products. Shoppers must trust the labels.
22. Which of the following is usually not sold in containers at large supermarkets?
23. What are the functions of containers?
24. Which of the following doesn’t need to be printed on labels?
25. Why must shoppers trust labels?

选项 A、Because they usually can’t see the actual product.
B、Because it is the law.
C、Because salespeople can’t be trusted.
D、Because they open the containers before they get home.

答案A

解析 最后一部分提到,我们在购物的时候,一般情况下,产品的包装会把产品遮得严严实实,即使是玻璃或透明的塑料包装.我们也只能看见产品的一小部分,我们没有别的办法,只能相信标签上所说的。英文段落最后几句话往往会有出其不意的观点或信息,应该养成注意首尾句的听音习惯。
