become so reliant on them. We even need them when we do anything. But it is bad for our eyes

of bed, they often check the weather, read the news and send messages to one or two friends.
After getting up, they often take photos of food and even whatever(无论什么) they can see with
their phones. They share their photos with their friends. The research also finds that users pick
up their phones more than 1,500 times to do different tasks every week. And the smartphone
users are on their phones for about three hours and sixteen minutes a day. That is to say,
people use their phones for almost one full day every week.

play on the phones at night. And mobile phones influence(影响) our sleep. Without using
