48 Mobile phones have become part of people’s life and there have been an argument about the safety of using them for many years. What’s your opinion? What might be the writer’s attitude towards mobile phone use? Why do you think so? scanning

49 Main points Supporting details Read the passage again and fill in the form below: Using a mobile phone doubles the risk of developing brain cancer. Digital mobile phones are an actual danger. The reasons why there is no definite scientific evidence available now about the effects of mobile phones on people ’ s health. The report is based on the findings of research that was carried out in Sweden, comparing 1,617 patients found to have brain tumors between 1997 and 2003 with the same number of healthy people. The study, conducted with 200 mice, of which half were exposed to radiation while the other half did not receive any radiation, shows that the first half were found to have more than twice the cancer rate of the second half after eighteen months. Enormous profit from the telecommunications industry prevents the bad results of findings from being revealed.

50  Limiting the amount of time you spend on your mobile phone  Moving the phone away from the body by using a handsfree kit or loudspeaking mode if available or why not consider texting as an alternative  Checking the SAR of a phone before you buy it, although the power which a phone transmits is controlled by the network and in many situations is far lower than its maximum power  Turning your phone off when you don ’ t need to use it … Possible solutions

55  Listen to the tape carefully Identify the most important information and less important These days, I have been considering buying a new mobile phone. First of all, I like the ones with MP3 function in particular, this way, music will accompany me wherever I go. However, a major consideration is the radiation from the mobile phones, So, I prefer one that will do least harm to the user. Certainly, it doesn’t matter so much whether it could be used as a camera, for I think the picture a mobile phone could take is not clear enough and it wastes a large quantity of power.

Is your uncle willing to buy an modern one at a high price? 3. Does the function of pronunciation matter a lot according to your uncle? He prefers a dictionary with two kinds of translation, for he thinks that,this way,his son can look up words in both languages No, he doesn’t want to spend more than 700 yuan on it Yes, he thinks that will help his son to pronounce the word properly
