【听力原文】
A lot of people cannot make it through the day without checking their Facebook or Twitter at least once or twice. According to a brand new study in Chicago, social network services are more difficult to resist than cigarettes or alcohol. One of the reasons the researchers gain is that people thought there were less consequences. If you check your Facebook at work, you won’t feel guilty. However, the researchers argue indeed there are serious consequences to Facebook. They’ll remove you from your real life experiences, urge it to create reality television version of yourself and cause you to think you have thousands of friends. And how could we withdraw from some of our social media? The researchers suggest we could put our cellphone use on schedule. We are going to check only at these times, even if we could plan to check it frequently, like once in an hour.
