“接通电源”常见的英文表达是 “turn on the power” 或 “switch on the power”。
turn on the power:强调通过操作(如转动开关)使电源接通。例如:Before you start the machine, make sure to turn on the power.(在启动机器前,一定要确保接通电源。 )
switch on the power: “switch”有“开关”之意,“switch on the power”更侧重于用开关来接通电源。例如:You need to switch on the power to light up the room.(你需要接通电源来照亮房间。 )
