Work in pairs and have a discussion about the three questions.

Sample answers:

S1: A mobile phone can now be used to receive phone calls, sent and receive messages, listen to music, watch videos, surf the internet and so on. I find it very useful to use the mobile pones to make telephone calls and sent and receive messages because we should always be informed and it's important and necessary to communicate with each other in modern society. I also expect a mobile phone to show pictures of the person I called so that we can see clearly whether we are calling the right person and I hope one day we can use it to have meetings with people in the distance, and see films and show DVD in public.

S2: Nowadays mobile phones can be used to do calculations, take pictures in life, play games, chat online, set time limit, wake up people, find out various information online and son on. I find they are very useful because we use them to play games and chat online and talk with friends about different subjects. I expect mobile phones can be used one day to watch TV, cook meals, pick up foreign languages, do homework and take exams for me. Then I'll be free from different kinds of worries and complaints about live a more comfortable and convenient life.
