社交圈的"飞行模式" 你中枪了没？

 　　Airplane mode (or flight mode) means someone cutsthemselves off from the world by not logging on to socialnetworking sites or checking their cell phones. This usuallyoccurs after a breakup or a rough work week.

　　“飞行模式”指不上社交网站，也不开手机，完全与外界切断联系的状态。这种情况通常在遭遇分手或者经过一周艰苦工作后出现。

　　This usage is derived¹ from the cell phone setting of the same name which suspends many of thedevice's signal transmitting functions – thereby² disabling the device's capacity to place or receivecalls or text messages.

　　这种用法来源于手机设置中的“飞行模式”，手机处于这种模式时，电话和短信等需要信号传输的功能都不能使用。

　　For example:

　　Dan won't answer your calls. He's in airplane mode.

　　丹不会接你电话的。他现在处于“飞行模式”。
