大学英语!阅读理解(3)!
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.
51.the cost of owning an appliance may include ____________.
a.the cost for maintenance and repairs
b.the difference in the price
c.the energy used by the appliance
d.both A and C
52.Annual cost for running a refrigerator may reach ____________.
a.about $30 b.from $30 to $50
c.from $50 to $ 80 d.over $ 80
53.Which of the following is NOT true according to the passage?
a.A more expensive appliance saves you more money.
b.a low-price appliance can cost you more money in other ways.
c.Refrigerators with the same capacity may not consume the same energy.
d.It is necessary to consider the cost of a refrigerator in different ways.
54.What are energy efficient appliances?
a.Those with a large capacity.
b.Those with a low energy consumption.
c.Those with a low initial purchase price.
d.Those with low cost of repairs.
55.What can be a conclusion from the passage?
a.The more expensive the appliance is,the better.
b.The less expensive the appliance is,the better.
c.Don’t buy an appliance that costs a lot for repairs and maintenance.
d.To buy an expensive but energy-saving appliance can be the choice.
