第2题
Saving energy means saving money. Homeowners know this basic fact, but they often don t kn
ow what kinds of adjustments they can make in their houses and apartments that will result in savings. For those willing to spend some time and money to reap long-term energy savings, an energy assessment is the way to go. An energy assessor will come into your home and assess its energy efficiency. The assessor will find out areas of your home that use the most energy and offer solutions to lower your energy use and costs. Trained energy assessors know what to look for and can locate a variety of problems that may be resulting in energy inefficiency, including inadequate insulation(隔热), construction problems, and uneven heat distribution. There are quicker and less costly measures that can be taken as well. One way to save money is to replace bulbs with fluorescents(荧光灯). This can result in a saving of more than 50% on your monthly lighting costs. When it s time to replace old appliances, it s wise to spend a bit more for an energy-efficient model, and be sure that you are taking advantage of energy-saving settings already on your current refrigerator, dishwasher, washing machine, or dryer. Windows provide another opportunity to cut your energy costs. Fill the holes or cracks of old windows that might be leaky to let in cold wind, and choose double-paned (双层)windows if you re building an addition or replacing old windows. Most areas of your home or apartment offer opportunities to save energy and money. The results are significant and are well worth the effort.

According to the passage, which of the following would an energy assessor do?

A.Change your light bulbs.

B.Fix construction problems.

C.Replace your old appliances.

D.Check your heating system.
