知识点解析

在我们生活中，我们用到开和关的次数简直是太多太多了。比如：开手机、开门、关上书、关电视等等。在中文里面，不论我们开关什么，就是只有“开”和“关”这一组词。但是，在英语里，至少有两组开关，他们就是：open/close 和 turn on/turn off。那么他们究竟有什么区别呢？? open将原来合上的东西打开，比如：open the window/door/book打开窗户/门/书open your eyes/heart/arms张开你的双眼/心扉/双臂? close和open对应? turn on指转动或推上开关等打开，比如：turn on the TV/light/switch打开电视/灯/开关turn on the water/shower/tap打开水/淋浴/水龙头? turn off与turn on对应看看是不是理解了呢？
