                The ALL NEW Dockland Split Type
                Air Conditioner(BA501)
Committed to producing energy-efficient products, Dockland Electronics has created the BA501, a new split type air conditioner with features designed to conserve power without compromising efficiency.
Speed Cooling
This function allows the unit to reach preset temperatures in a short time.
Temperature Equalizer
This function enables the unit to cool areas evenly by using dual-direction air vent technology.
Sleep Mode
This function decreases the cooling temperature after the unit’s first two hours of operation and maintains the room temperature for the next five hours before it automatically shuts off the unit.
The BA501 is equipped with a patented refrigerant and has a Seasonal Energy Efficiency Ratio(SEER)rating of 14. SEER measures the energy efficiency of air conditioners. [br] What is stated about the SEER rating system?
选项 A、It is used by countries with limited fuel supplies.
B、It was set by an international organization.
C、It measures the durability of appliances.
D、It calculates the energy performance of machines.
答案 D
解析 本题应将选项中与the SEER rating system有关的语句带回到原文中去查找并判断正误。(A)、(B)、(C)在原文中都未提到。而根据文中提到的“SEER measures the energy efficiency of air conditioners．”一句，可知SEER可以测定空调的能源使用效率，因此选(D)It calculates the energy performance of machines．。
