【正确答案】陈述
   Candidate A: Whether we like it or not, the smartphone has become an inseparable part of our daily life. Besides the two basic functions of it, making calls and text messaging, the smartphone nowadays is so smart that we cannot live without it. For example, WeChat gathers all our friends within one circle. We can chat with friends, post photos and share articles on it. It also supports payments between users and one-click payments. Applications such as Taobao and Jingdong have made shopping more convenient. With just a few clicks, goods will be delivered to our doorstep. Other useful applications such as Gaode Map, Youdao Dictionary, and Zhihu can meet almost all our demands and provide us with lots of help in our life and study. As the saying goes, nothing is impossible. The same is true of the smartphone.
   Candidate B: The whole world is occupied by smartphones now. There has never been such a thing in history that is so prevalent in the world. People are looking at their smartphones everywhere, on the bus, on the train, in the subway, in the café, in the restaurant, and even in the toilet. People are so obsessed with smartphones that they care less about the relationship with others. I recently learnt two new words, "phubber" and "cellfish". "Phubber" refers to a group of people who always look at their smartphones and are indifferent to the surroundings. "Cellfish" refers to those who lower their heads, looking at smartphones instead of talking with friends sitting next to them. These are true pictures of modern people's life. Isn't this a reflection of the decline of human relationships? I am really worried about it.
   讨论
   Candidate A: The smartphone nowadays is truly as powerful as a minicomputer. We can do almost anything on it. It is just like a huge information centre packed into a small box which we can take with us anywhere. I don't see any reason to abandon it.
   Candidate B: I didn't mean to abandon smartphones. But I do think people should stop for a while and look up from their smartphones to observe the whole situation. We are addicted to it too much.
   Candidate A: As to the problem of addiction, I think it's completely a personal thing, ff you think you should stay away from it, then drop it, and do something else.
   Candidate B: Well, I don't think it's a personal thing. It's a social problem. Everybody's time is limited. When the social softwares in your phone consume too much of your time, surely you have less time to do other meaningful things.
   Candidate A: I don't know what your personal definition of "meaningful things" is. As far as I'm concerned, I communicate with my friends through WeChat, which saves money on my telephone bill; I book plane tickets and train tickets on my smart-phone, which saves my energy and time.
   Candidate B: In my opinion, the "meaningful things" are what we call effective social interaction. If you want to know someone, the best way is to talk to him face to face, rather than just click the "like" button under the images or articles he posts on WeChat.
   Candidate A: The smartphone is a typical product of modern science. Science changes our life. To refuse innovation means to die in the future.
   Candidate B: Modern science does not always create good things, for example, nuclear weapons. We must raise awareness of the negative influence of the powerful products.
   Candidate A: The development of history is always combined with unnecessary worries. But history never stops its wheels and we are always making progress.
   Candidate B: I never deny the powerful functions of the smartphone. But I still insist that a meaningful life is to go out and interact with people. Anyway, outdoor activities and social communication are the instinctive needs of human beings.
