Topic 17: There are social, medical and technical problems associated with the use of 
mobile phones. What form do these problems take? Do problems of using mobile phones 
outweigh the benefits?
 
(speak at an increased volume) (uncomfortable)
(intercept) (eavesdrop in);
(increase the risk of suffering cancers) ;
(talk on the phone wh.ile driving), (correlation with road traffic accidents)
(send text messages ) (make voice calls); (Internet browsing), (music playback), (personal organizers),
(email). (built-in cameras), (ringtones), (games );
 
(in the event of an emergency),(locate trapped or injured people using the signals from their mobile 
phones)
Across the world, especially the wealthier parts, the mobile phone has taken the place of 
telephone as an electronic telecommunication device, with the majority of the adult, teenager and 
even child owning one. As this technology has become rife, its drawbacks, which can be seen 
from social, medical and technical perspectives, deserve people's greatest attention.
Similar to many other hi-tech products, such as computers, mobile phones have detrimental 
effects on users' health. For example, long-time heavy phone users seem to be more prone to 
certain types of cancers, although evidence to date is inconclusive. Another lethal health concern 
is the link between mobile phones and road accidents. It is argued that motorists have a much 
higher risk of collisions and losing control of the vehicle when driving and talking on the phone 
simultaneously, despite sometimes using hands-free systems.
When the mobile phone has brought considerable convenience, people's obsession with 
convenience has meanwhile caused enormous disturbance. That's why the use of mobile phones 
has been prohibited in many public places, such as libraries, theatres, hospitals and even 
transports, such as trains, buses and aircrafts. Speaking at increased volumes considered impolite 
or even offensive. In schools, students are required to switch off cell phones before the class 
begins because mobile phones are responsible for a high amount of class disruptions.
When its downside persists, the mobile phone has proven indispensable in modern life. It is 
handheld, lightweight, portable and multi-functioned, allowing users to send text messages, 
exchange music files, make voice calls, browse Internet, and so forth. Meanwhile, within twenty 
years, mobile phones are expected to be more pervasive as technical advances and mass 
manufacture will make them low-cost personal items. Given those factors, the mobile phone will 
continue to perform its role as a key social tool, by which one keeps in touch with others much 
more easily than did the generations before.
As suggested above, the contribution of the mobile phone to the society is prominent and 
people's dependence on it for communication is an irreversible trend, although it has a number of 
problems that should be well handled.
