问题 Bright ideas for cutting the electricity expenses
Cutting domestic electricity costs is getting more important for many homes since electricity costs have climbed inexorably higher over the past few years. Here are a few ideas for cutting electricity expenses.
1. Use extra blankets instead of having the heater on at night. Once you’re snug under the covers, you don’t really need artificial heat unless you live in a state where the temperatures drop below freezing.
2. Wash only full loads in the dishwasher and washing machine. A lot of electricity and water is wasted on small loads.
3. Use power strips to turn off multiple devices. Power strips can include a switch to turn all devices on and off.
4. Replace incandescent light bulbs with florescent light bulb, which has the same brightness and use less energy, without replacing light fixtures. Use the motion sensor to reduce the usage of electricity in non-working areas where the light is not constantly used, such as the storage or closet.
According to the information, how can people reduce electricity expenses?
选项 A、By purchasing a cutting edge light fixture.
B、By using incandescent light bulbs.
C、By using brighter light bulbs
D、By installing motion sensors in non-working areas.
答案D
解析 节约电量方面比起白日灯更提倡使用荧光灯，不工作的空间里一般提倡安装感应灯。
