Tips:
"open"的反义词一般用"close",意思是“关闭、合上”,所以“合上书本”是"close the book",“关上门”是"close the door"。
02 turn on

用于打开某种电器或某种设备
1. 自来水/ 煤气

注意:此处要与“打开电脑文件”区别!
"turn on"可以理解为拧开。通常用于电器或设备,使其运作。所以开灯的英文表达是"turn on the light" ,不能使用"open"~
switch on与turn on在绝大部分地方可以互换
主要用于电器
例如:
switch on the oven 打开微波炉
switch on the lamp 打开台灯
Tips:
"turn on"的反义词是"turn off",“关灯”就是"turn off the light"。
