Much like how we struggle to operate at the same speed in intense heat, it can be something similar for the phones processor - a chip inside thats responsible for its main functions. As the d
3、evice gets hotter, the processor tries to stop itself overheating, and it ends up slowing everything down as a result. The hotter they get, the harder they have to work and the more energy they use, which means the battery life gets drained more quickly. They also use energy to monitor their own sta

15、喝完第10杯冰咖啡的你，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，手机电池还要消耗部分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.A13.D14.C15.B
