MOBILE PHONES
We love them so much that some of us sleep with them under the pillow, yet we are increasingly concerned that we cannot escape their electronic reach. We use them to convey our most intimate secrets to friends, but also we worry that they are eroding our privacy. We rely on them more than the internet to cope with modern life, and we absolutely cannot imagine our life without them.
As researches show these are teenagers who regard their mobiles as an expression of their identity. This is partly because mobiles, are beyond the control of parents. But the researchers suggest that another reason may be that mobiles, especially text messaging, help to overcome shyness. Young people often use texting to apologize, to excuse lateness or to communicate other things that make them uncomfortable.
But while the research points out that mobile phones now boast twice the reach of the desktop internet, it argues that the impact of phones has been local rather than global, shoring up existing friendships and networks, rather than opening users up to a new broader community. Even the language of texting in one area can be incomprehensible to anybody from another area.
Lets consider some of advantages and disadvantages of mobiles. In travels like in everyday life we can need help in a case of incident. In chance of any kind of accidents we can inform with mobile phone suitable services, such as: police, fire guard or ambulance service. What is a more, young people, using the mobile phone learn to take care of themselves, because when their parents will buy them a card mobile phone, the users know, how much money they can afford to spend on a definite time. It teaches them, how to save money.
Furthermore thank to mobile phones, parents can control their childen during their house absence. They can always call kids to find out where they are, what they are doing, why they arent at home and what time they are coming back. It is also possible to give them recommendations, such how: "Make purchases! or "Visit your grandma today etc.
On the other hand some people say that mobile phones restrain interhuman contacts, because people prefer to talk on the phone with their friends instead of for example meet with them.

Mobile phones arent also sensible for our health, because they emit harmful rays. But on the other hand almost everything has some negative signs, but we dont have to worry of them. The most important trump of mobile phones is comfort and if we will use this kind of phones with reflection, it can really help us and be very useful.

The title of every passage.

Do you think mobile phones were a good invention?
Are there any places where you think mobiles should be banned?
How have mobile phones changed since the 90s?
What do you think mobile phones will be like in 20 or 100 years time?
What will you be able to do with your phone?
How big will it be and what will it look like?
