 阅读理解One recent report found that adults in the US check their phones, on average, 344 times a day—once every four minutes—and spend almost three hours a day on their devices in total. The problem for many of us is that one quick phone-related task leads to a quick check of our email or social media feeds, and suddenly we've been trapped into endless scrolling (刷屏). What we do know is that the simple distraction of checking a phone or seeing a notification (提示) can have negative consequences. This isn't very surprising; we know that, in general multitasking harms memory and performance. One of the most dangerous examples is phone use while driving. One study found that merely speaking on the phone, not texting, was enough to make drivers slower to react on the road. It's true for everyday tasks, too. Simply hearing a notification "ding" made participants of another study perform far worse on a task-almost as badly as participants who were speaking or texting on the phone during the task. In one recent study, for example, researchers asked participants to either put their phones next to them so they were visible (like on a desk), nearby and out of sight (like in a bag or pocket), or in another room. Participants then completed a series of tasks to test their abilities to process and remember information, their problem-solving, and their focus. They were found to perform far better when their phones were in another room instead of nearby—whether visible, powered on or not. That held true even though most of the participants claimed not to be consciously thinking about their devices. Our brains may be subconsciously hard at work in preventing the desire from checking our phones, or constantly monitoring the environment to see if we should check our phone (eg. waiting for a notification). Either way, this distracted attention can make doing anything else more difficult. The only "fix", the researchers found, was putting the device in a different room entirely. （1） What did the recent report in Paragraph I find? A . Multitasking is very dangerous. B .
