A. A mobile phone, also known as a cell phone, is one that we can use to make telephone calls to anyone from a great distance via a radio link. Apart from telephony, modern smart mobile phones also support a number of other services including text messaging, internet access, gaming, photography, and many business applications.
The first cell phone weighed about 2 kilograms and was demonstarted in 1973 by Dr. Martin Cooper and John F. Mitchell of Motorola. Ten years later, in 1983, the first model of cell phone went on sale to the public. By 2011, over six billion people, 87% of the world's population, used mobile networks. In spite of the many advantages a cell phone has, it also brings about several problems that users should be awave of. Mobile phone radiation is believed to be harmful to human health. Some recent studies have found an association between cell phone use and certain kinds of brain disease. Another serious problem can be privacy and tracking. Once users have the phone on, they can be interrupted in many ways, and they can also be tracked by location data.

B. Texting is a new way of exchanging information, and it is becoming more and more popular among the young. In fact, texting is clearly affecting on the language. There are no rules for it. We are creating a new aspect of vocabulary and opening up a new kind of playful and that's fine, but some people are worried about the affects it might have on child' ability to read and write. But not everyone is so worried. An expert says, "Every time a new medium comes along, it has an effect on language... but this doesn't destroy the existing language, it adds to it". In text massages, words may come from shorthand created in email such as CUS (See you soon) and so on. Someone says, "Mostly they are original, but sometimes you get a class os meanings. For example, LOL can mean both Laugh Out Loud and Lots of Love. That could lead to some misunderstanding."
