Question

In order to save energy, the school is going to _____ the power supply of an air conditioner in every room for five minutes during the noon time.
(A) put down
(B) turn down
(C) shut down
(D) go down

Accepted Answer

正確答案為 C。 本題測驗片語動詞，shut down 意為「關閉（電源、機器）」，符合關閉冷氣電源以節約能源的語境。 (A) put down 意為「放下、鎮壓、安樂死」，無法與 power supply（電源供應）搭配，語意不合。 (B) turn down 意為「調低（音量、溫度等）或拒絕」，雖與電器有關但指調降而非關閉，與 save energy 搭配關閉電源的語境不符。

In order to save energy, the school is going to _____ the power supply of an air conditioner in every room for five minutes during the noon time.
