There are social, medical, and technical problems associated with the use of mobile phones. What forms do they ta
14、ke? Do you agree that the problems outweigh the benefits of mobile phones?手机的优点：1.mobile phone makes our lives more convenient.* cell phones now have features beyond sending text messages and making voice calls, including Internet browsing, MP3 playback, memo recording, email, built-in cameras, Blue
15、tooth connectivity, video calling, etc.2. They also make people work faster and efficiently, because people can communicate with their clients and colleagues by the mobile phone.3.

Apart from the health problems, a range of technical defects would give rise to a series of dangers. For instance, using mobile phones on board a plane may affect the navigati
