In order to examine the effects of cell phones on people ’ s lives, we presented cell phone owners six effects that might result from mobile phone ownership and these effects were balanced ( 均衡 ) between positive ( 正面的 ) and negative ones. These answers indicate that mobile users see mostly positive benefits ( 益处 ) to mobile technologies — but also some drawbacks ( 缺点 )about the constant connectivity that cell phones offer. When it comes to the positive effects of cell phone ownership, two-thirds (65%) of cell owners say that mobile phones have made it “ a lot ” easier to stay in touch with the people they care about, while just 6% say that their phone has not improved their connections with friends and family at all. About half of cell owners say that their phone has made it at least somewhat easier to plan their daily life, and to be productive ( 有成效的 ) while doing things like sitting in traffic ( 交通 ) or waiting in line. When it comes to the “ dark side ” of cell phone ownership, roughly one in five cell owners say that their phone has made it at least somewhat harder to forget about work at home or on the weekends; to give people their full attention; or to focus on a single task without being distracted ( 分心 ). Most cell owners say that their phone has had no effect at all on their life in any of these negative ways. In all, cell owners are far more likely to view their phone as a time-saver than as a time-waster. Some 33% of cell owners agree with the statement ( 说法 ) that their phone “ saves you time because you can always access the information you need, ” while just 3% agree with the statement that their phone “ costs you time because you are constantly distracted. ” The largest proportion ( 比例 ) of cell owners (56%) say that the time costs and time savings offered by cell phones pretty much balance each other out.
