【回答】
Dear editor, I’m writing to you about a common phenomenon to draw it to the public attention. With smart phones widely used, there are more and more Phubbings. As is often the case, when people are having meals, waiting for buses or even walking along streets, they are always addicted to their phones, heads hanging down, completely ignoring others. The reason for the increasing number of phubbings everywhere is that smart phones nowadays can be used for people to do nearly everything, such as playing mobile games, shopping online and keeping in touch with friends through QQ. However, too much exposure to phones is harmful for their health and safety. Moreover, people engaged in phones fail to communicate well with those around them. Personally, people should wisely use their phones to help with their work and study. Meanwhile they’d better care more about their family and friends rather than phones. Best wishes to you! Yours truly, Li Hua
