Many of us have become so reliant( 依赖的 )on our smartphones that we use them to carry out a staggering( 令人难以相信的 )221 tasks every day. A study of 2, 000 smartphone owners shows that the average user reaches for their phone at 7: 31 am each morning, to check personal emails and Facebook. And before they’ve even got out of bed, the majority of people check the weather, read the news, and send a text or two to friends. It also appeared that people will check the train times, do their banking and update Instagram early on in the day. In an average week, the research discovered that users pick up their phone more than 1, 500 times to complete various tasks from emails to playing games and posting to social media. And the average smartphone user is on their phone for three hours and sixteen minutes a day. This amounts to almost one full day a week using their phone, so it’s no wonder almost four in ten users admitted feeling lost without their tool. Many owners also admitted to finding themselves using their phone without realizing they’re doing so, with two thirds saying they have managed to log in and browse Facebook without thinking. And surprisingly, four in ten said they have, at one time or another, checked their emails automatically( 自动地 )without thinking. The study has also revealed that our smartphones are now becoming more of a‘go-to-gadget’, replacing desktops and laptops, which people only turn to for, on average, 140 tasks in a typical day.
