Question

You go shopping for a new refrigerator, and you’re on a budget (手头拮据). Are you sure that the best buy is “the fridge with the lowest sales price”? Not necessarily. When you buy the lowest-priced refrigerator, you may end up spending more than if you buy a more expensive one. The reason is that the cost of owning a home appliance consists of three components: the initial purchase price, the cost of repairs and maintenance, and the cost to operate it.

To figure out how much you’ll spend over the lifetime of the appliance, you have to look at all these costs. The appliance with the lowest purchase price, or even the best repair record, isn’t necessarily the one that costs the least to operate.

Suppose you’re in the market for a new refrigerator. Different models of refrigerators with the same capacity can vary dramatically in the amount of electricity they use. For example, the annual electricity consumption varies from a low of about 600kilowatt-hours a year to a high of more than 800 kilowatt-hours a year. That means the annual cost to operate refrigerators can range from about $50 to $80. A $30 difference in annual operating costs might not sound like much, but remember that you will enjoy these savings year after year for the life of the appliance otherwise. As a result, you may actually save money by purchasing the more expensive, more energy-efficient model.

理由∶
21、问题问到拥有一个家用电器的成本，选项A和C都是正确的。维护和维修的成本以及耗电费用是家用电器成本的一部分，故答案为D。

22、题干问到制冷机每年的运行成本大约是多少。根据文章中的数据，这个成本约为50至80美元之间，因此选项C是正确的。

23、根据文章内容，A选项的说法是错误的。质量更好的电器或许更耐用，但更加昂贵的价格不代表一定能省钱。B选项是正确的，C选项是正确的，D选项也是正确的，因此选择哪个选项都需要根据文章具体情境来判断。该题目问的是不正确的说法，因此答案为A。

24、文章提到“能源效率高的家用电器”指的是耗能更少的电器，因此答案为B；A、C、D选项都与文章的内容不符。

25、文章告诉我们在购买家用电器时考虑不同方面的费用，比如购买价格、维修费用以及耗电费用等。然后文章指出，高价的家用电器可能在长期使用中能够节省维护和更换的财务成本，而地球更篮促使我们购买能耗低的家用电器。因此，根据文章的内容，D选项是正确的。
