Step Ⅲ LISTENING (Workbook)

T: Millions of people in China and around the world use cellular phones. They are such great inventions -with a cell phone, you can talk to anyone on the planet from just about anywhere! These days, cell phones provide an unbelievable array of functions, and new ones are being added at a breakneck pace. Now look at the pictures and questions on page 62. 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, send and receive messages, listen to music, watch videos, surf the internet and so on. I find it very useful to use the mobile phones to make telephone calls and send 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 call 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, record pictures in life, play games, chat online, set time limit, wake up people, find out various information online and so on. I find they are very useful because we can enjoy ourselves when 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 and live a more comfortable and convenient life in the future.

T: Good! You have known much about mobile phones and we'll listen to some other functions of them, which you might feel more interested in. Now, listen and do Part 2 and then answer the questions in Part 3. While listening, please make notes as follows. OK?
