15、啡的你，准备刷会儿手机。但你发现手机要么卡 顿、发烫，要么就是快没电了。这个场景听起来很熟悉吧？在酷暑天气里，我们很难按照往常的进度做事，其实手机处理器的工作原理也是如此。 处理器是指手机内置的芯片，负责各主要功能的正常运转。随着手机温度升高，处理器就会 暂停工作以防过热，最后就导致手机越来越慢。手机电池的温度越高，就越难以运转，而且消耗的能量也会更多，这就意味着电池寿命 消耗得会更快。并且，手机电池还要消耗局部能量来监测自己的运行状态，基本上到最后就 是电池要完成更多的工作。（译者注：本段中的they指的是battery,即手机在发热状态，电 池能量消耗迅速。）那么你可以做些什么，给手机降降温呢？不要一直插着充电线。在你给手机充电的时候, 机身温度就在上升。所以如果你一直给手机充电，到最后它就会变得很烫。你可以取下手机 壳，并退出所有你不需要的后台程序。另外，不要把手机贴在冰袋上，因为这起不到什么作 用。温度快速变化对手机是非常不利的，并且冰块受热融化后可能会导致手机进水。 拓展练习阅读理解参考答案 12.A 13.D 14.C 15.B
