Nowadays, mobile phones are more and more popular, especially ____ teenagers. Those people ____ like to play with mobile phones all day ____ (call) phubbers. One of the ____ (reason) is that it is fun for them ____ (spend) time playing with new kinds of mobile phone software, such as ____ (chat) on Wechat. I think spending too much on mobile phones is bad for everyone. For a student, it will not only get in the way of study but also influence our health. My cousin was so ____ (interest) in mobile phone games ____ he lost his interests in any other subject. And he didn't enter the best high school in the town ____ he did well enough in school when he ____ (study) in primary school.

    In my opinion, it's time to stop using mobile phones while we are studying, working, driving or walking. It's too dangerous to do that. Let's call on more young people: Don't be phubbers!
