Note that you do not use open as a verb or adjective to talk about electrical devices. If someone causes an electrical device to work by pressing a switch, you say that they put it on, switch it on, or turn it on. It's too easy just to switch on the television. If the device is already working, you say that it is on. The answering machine is on... He cannot sleep with the light on.
注意， open 作动词或形容词使用时，不能表示打开电气设备。如果某人通过按开关打开电气设备，可以说 put on, switch on 或 turn on：It's too easy just to switch on the television（打开电视机实在是太顺手了）。如果该设备已在运转，用 on 表示：The answering machine is on（电话答录机是开着的），He cannot sleep with the light on（灯开着他睡不着）。
