Benefits and Negative Effects of WeChatWeChat is a popular and powerful mobile communication tool. Every ten smart phones, nine of them have been installed with Wechat app.WeChat provides multi-functions such as text and voice messaging, photograph and video sharing, QR code scanning, blog posts (Moments), mobile commerce and so on. It can also integrate with other social networking services such as Facebook and Tencent QQ.While talking about the convenience that Wechat has apparently brought to our daily communication, we mustn’t ignore the negative effects Wechat has created.Firstly, Wechat is killing face-to-face interaction. The hard screen blocks our true feeling expressions which are necessary for our successful communication. Secondly, Wechat produces a huge number of people who are glued to their phone screens. It is common to see people texting or sending voice mails or using any of its other functions on the streets as well as public transportations. Thirdly, the app asks for access to your phone contacts, locations and camera. Though such request is common with all mobile online social networks, privacy leakage can be a serious problem.In short, how to reduce the negative effects of WeChat while enjoying its benefits is still a question for us to consider.Activity 1Reading comprehension: What functions does WeChat have according to the text?
