Помогите сделать ex. 12 ДАМ 50 баллов срочно

I’m in favour of using computers for a number of reasons. First of all, I think that computers make the search for information through the Net more effective and faster if to compare it with doing the same using just books. So, it makes our life more easier. Secondly, I think computers help us to make our works more interactive - like you can make a presentation, make videos with special effects, some animations and many other things that can make your work more interesting. And finally, it’s a good way to spend your free time if you, of course, know how to balance your time. There are a lot of good stuff there. For example, of course, the Internet, then some social medias for communicating with friends, electronic textbooks, news, shows, programs for creating videos and other good things. Also you can use it at any time you want to. You just turn it on and, for example, type some kind of text in Miscrosoft Word twice faster than you would write it down by hand.
