What is true for you?

  Mobile phones are good for young people. 

Mobile phones are bad for young people.

 

Look through the articles. Which of them are for and

 which against using mobile phones.

 

       1. Kids sometimes lose their phones at school or use them in lessons.

You don’t need a mobile phone when you are at school because your friends are with you. It’s better to talk to people without a phone.

 

       2.In Bangladesh the government wants to ban mobile phones for under sixteen-year-olds because they might cause brain damage. They are more dangerous for teenagers than they are for adults because teenagers’ skulls are thinner. Also, many teenagers in the UK have their phones stolen. This could be a very frightening experience. 

     3.In fact, mobile phones are good for young people! British

teenagers used to carry a packet of cigarettes, now they carry a

 mobile phone. The time that they used to spend smoking, they

now spend talking. British teenagers are smoking less so mobile

phones are healthy! Also, a lot of parents feel that kids are safer

if they carry a mobile phone.

   4.Mobile phone make it easy to meet your friends at lunchtime

 or after school. They are good for emergencies, too. Your parents

 don’t have to worry about you because you can always phone

them.

 

 

Mobile phones and our life

HISTORY 

Though the technology of mobile phones increases rapidly everyday we are sure that people know very little about history of this invention of civilization. And we are glad to introduce to you some information about it, which we hope you’ll find interesting and maybe useful.

 

Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered to be the inventor of the first modern portable handset. Cooper made the first call on a portable cell phone in April 1973. He made the call to his rival, Joel Engel, Bell Labs head of research. Bell Laboratories introduced the idea of cellular communications in 1947 with the police car technology. However, Motorola was the first to incorporate the technology into portable device that was designed for outside of an automobile use.

In 1981, Motorola and American Radio telephone started a second U.S. cellular radio-telephone system test in the Washington/Baltimore area.

 

Despite the incredible demand, it took cellular phone service 37 years to become commercially available in the United States. Consumer demand quickly outstripped the 1982 system standards. By 1987, cellular telephone subscribers exceeded one million people.

When mobiles were first launched, each country was limited to its own national area - they could call overseas landlines or mobiles but they would not work overseas. The first mobile phone weighed 76lbs (34kg).  

Influence

    

There is no need to prove a fact that mobile phones are very popular today. But when we are using it, of course we don't think about danger that it puts us in. Some people do think about their children and themselves and, naturally, try to protect their health: some of them do it by buying special electronic equipment which protects you from harm the mobiles bring. But there are too little of them. Maybe after this project everyone will pay more attention to their health.

     So, there are two fields of influence which the mobile phones harm most: brain and blood (of course, we know about harm to our eyes but this is not as important as the first two).

A major study carried out by scientists in Finland suggests that radiation from mobile phones causes changes to the brain. Professor Darius Leszcynski headed up the two-year program at Finland’s Radiation and Nuclear Safety Authority.

The researchers discovered that radiation from mobile phones can cause activity in hundreds of proteins in human cells grown in a laboratory. It is the first time that scientists have looked at the effects of mobile phone radiation on human cells rather than those of rats.

 


 

          За последний год телефон из игрушки и мерила богатства превратился в обычный рабочий инструмент, каким он и должен быть. Сотовыми пользуются практически все, и звонок сотового телефона можно услышать сегодня где угодно. Так, очень часто телефоны звонят на спектаклях, а еще чаще в кинотеатрах, что, на мой взгляд, является недостатком воспитания их владельцев. Могу поспорить, что за 5 минут в центре города вы сможете насчитать больше десятка сотовых у проходящих мимо людей. В первую очередь, такая доступность связана с постоянным снижением стоимости самих трубок и, конечно же, значительным снижением стоимости минуты разговора у операторов сотовой связи. Армия пользователей мобильных телефонов пополняется новобранцами, а те, кто имеет телефон достаточно давно, сегодня могут позволить себя говорить в несколько раз больше, но за те же деньги, нежели всего два года назад. Отсюда и вытекает главный вопрос данной статьи, а так ли безопасен сотовый телефон, как мы думаем?
