“WeChat” is a new and powerful mobile communication tool. It supports sending voices, videos, photos and text messages. You can also do group chats, or you can find new friends nearby to talk to.

Recently, “WeChat” is becoming more and more popular in China. People can sign up and leave text or voice messages for free, no matter where they are. They can also find a “stranger” to talk to __（A）__ “shaking the phone”. The system will find out others who are shaking their phones at the same time and make a match. Another amazing function is that WeChat can help to search for people who live nearby with the program on, and show the rough (大体上) distance. I like this function best, __(B)__ it can help you to find more people who you may know.

Recently, I read news that some stupid girls meet guys they knew by shaking the cellphone and there were unpleasant incidents (事件) after they met. It obviously showed a lack of common sense(常识). They should learn to protect themselves and not trust strangers so much.

(C) Technology makes life easier and sweeter, and at the same time it brings us bitter lessons. Being vigilant (警戒的) is necessary.
