Привет! Я попробую тебе помочь :)
Я когда - то готовилась к олимпиаде и брала тему "Why do we need mobile phones?" ("Почему нам нужны мобильные телефоны?") Вот напишу тебе некоторые предложения!

Today, the role of mobile phones in human life is difficult to overestimate. With this compact device at any time we can quickly contact with their relatives and friends, work colleagues, we are interested to find out information. You do not need to strain your memory and remember the phone an old friend, who has long been recruited, notebook mobile phone is always to hand. Many in addition to the contacts stored in the phone still a lot of other information - write down their thoughts and ideas, credit card numbers, anniversaries, various files, etc. That is, substitute for us right notebook and flash-drive. And all sorts of useful programs, functions, options, which are equipped with modern cell phones have made this small-sized unit is so versatile that sometimes you wonder.Almost everyone these days has a mobile phone and many of us would be unable to live without one. However, there are people who argue that we should not be able to use mobile phones whenever we like. There is no doubt that mobile phones are extremely useful. This is particularly true when you need to contact someone and no ordinary phone is available. For example, if your car has broken down and you need assistance, having a mobile phone might mean that you do not have to leave the car and walk a long way to find help. On the other hand, there are many situations when mobiles can cause problems for other people. If you are in the cinema or in the theatre, for instance, a mobile ringing can be extremely annoying. There are also times, such as in class at school, when it would be disrespectful to have a mobile switched on. A further argument that is made against mobile phones is that they damage our health. Most scientists, however, believe that is not the case. To conclude, mobile phones make our lives easier in many ways. In my opinion, there are occasions when using a mobile is not appropriate and we should always consider other people before deciding whether to have our phone switched on or not. Although some people believe that mobiles are bad for our health, I personally do not accept that argument, because I do not think that should be a reason for restricting their use.
