Помогите срочно ! нужно сделать краткий пересказ на английском (именно письменно пересказ ,а не только план )

текст:
If you are a typical teenager today, you use your MP3 player on the way to school, you text your friends all day and then surf the Net, send emails, instant messages or play on your games console in the evenings. In my opinion, teenagers are completely hooked on technology and I believe this has a positive effect on their lives. To start with, using the gadgets and devices that are available because of new technology makes life more enjoyable. For example, MP3 players make travelling more entertaining. In addition, media devices such as mobile phones and laptops allow access to information and entertainment and make communication easier and faster. Secondly, technology is a valuable resource that has allowed teens to learn new skills. For instance, many teenagers today are able to multi-task and do research using the Internet. Furthermore, they have learnt keyboard and computer skills that will help them at school and later in their working lives. On the other hand, there are those who believe that technology has had a negative effect on today's teenagers. They say that teens become distracted and waste their time with their gadgets instead ot concentrating on more important things such as schoolwork. As a result, teens become antisocial as they prefer to communicate digitally instead of face-to-face. In conclusion, teenagers' use of gadgets and devices enriches their daily experiences in many ways. As technology advances. I think teenagers will be better prepared for the future.
