【用法归纳】辨析turn on, turn down, turn off与turn up
turn on与turn off, turn up与turn down均互为反义词组。turn down表示“关小、调低(音量)”; turn off表示“关掉”;turn up表示“开大、调高(音量)”; turn on表示“打开”。如:
Miss Wang walked into the room and turned on the light.王小姐走进房间,打开了灯。
He turned on the computer and got online.他打开电脑上网。
注意:on, off, up, down这四个词都是副词,在使用过程中,当宾语为代词时,只能置于动词和副词之间;当宾语为名词时,既可置于动词和副词之间,也可置于副词之后。如:
The radio is too noisy. Please turn it off.收音机太吵了,请关了它。
Turn the gas on或Turn on the gas.把煤气打开。
