今天前程百利小编为大家分享的是托福听力最新科技文章。备考托福听力对背景知识是否了解也是很重要的一个方面。对背景知识有一个深入的了解才能减少在听的过程中的阻碍。了解背景知识另一个重要的方面就是对即将听到的文章有一个猜测预测性，这样才能更好的备考托福听力。
Background app updates(更新), cell tower pings(发出碰撞声) and other hidden activity accounts for almost half the battery drain(电池浩劫) on Android phones.
段落大意：背景应用的不断更新使手机的电池耗电量不断增加。
Smartphone battery down to 10 percent? Time to turn down the brightness on the screen, right? It's a classic strategy to squeeze(挤) more juice from the battery. And it works. But that trick might be less effective than you think. Because it turns out nearly half the battery drain on a phone happens when the screen's not even on. So says a study presented at a meeting of the Association for Computing Machinery, in Portland, Ore.
段落大意：当手机电量为10%的时候，一般情况下我们会把手机的屏幕变暗，甚至于关闭屏幕。但是这样也不能使手机停止耗电。
Researchers eavesdropped (偷听)on the activity of more than 1,500 Android phones—specifically(特别的), the Samsung Galaxy S3 and S4. They used an app they developed called eStar Energy Saver. The app logs the energy drain of the phone's apps and activities as they happen. (And you can try out eStar Energy Saver yourself, if you have an Android.)
段落大意：研究者通过窃听手机，发现有一款APP可以帮助Android系统的手机节约用电。
They found that some 45 percent of the battery drain happened while the screen was off. A lot of that energy suck (吸收)was apps updating in the background—downloading headlines(标题) and weather, while you're not actively using them. And different versions of the same app require different energy supplies. For instance, some versions of the Facebook app were twice as energy thirsty as other versions. So app version choice could slow your battery drain.
段落大意：他们发现即使把手机的屏幕关闭，它也会耗掉45%电量。所以大家在选择应用程序的版本时，要注意一下，正确的版本可以帮助你的手机节电。
But one of the most hidden energy draws, zapping(消灭) 12 percent of the battery, was just cellular(移动电话) paging: the pings from a cell tower every 1.28 seconds, that tell your phone if a call or message is on the way. Which is, ultimately, the price of being connected.
段落大意：当手机有电话和短信时，这时手机链接信号塔也会导致电量消耗。
