问题     The cost of heating your home, particularly during the colder winter months, makes up about 60% of energy bills. If you need a new boiler (锅炉), make sure you buy one of the best boiler brands.
    The first question you should ask yourself if you want the most energy efficient boiler is what type of boiler you should buy. All modern boilers that you can buy are condensing (冷凝式) boilers, which are much more efficient than traditional non-condensing boilers. According to a study, you could save as much as £ 340 a year on your gas bill if you’re trading in an old-style non-condensing boiler for a new condensing one.
    Getting the wrong type of boiler for your home results in unnecessarily high bills. Learn more about the different types of boiler and which would suit you best in our full guide to the different types of boiler.
    Once you’ve decided on the type of boiler you need, the next key question is the size. The size of the boiler in the context of efficiency is its heat output. The higher the heat output of the boiler, the more energy it will be using when it’s switched on. In most cases, larger homes with more radiators (散热器) and more bathrooms will need a larger heat output than smaller ones. Learn everything you need to know about picking the right size boiler for your home in our free guide on how to buy the best boiler.
According to the passage, people pay more than half of their energy bills for________.
选项 A、heating their home
B、lighting and cooking
C、cooling their houses
D、powering electric devices
答案A
解析 细节辨认题。由题干中的energy bills定位到第一段第一句。定位句指出，家庭供暖的费用，尤其是在寒冷的冬季，约占能源账单的60％。题干中的more than half of their energy bills是60％ of energy bills的同义转述，由此确定A)“家庭供暖”为本题的答案。原文未提及B)“照明和烹饪”、C)“家庭降温”和D)“驱动电器”，因此均可以排除。
