I tried several writing task 2 in Ielts test, here two of them,,:-)

Compare the advantages and disadvantages of three of following as media for communicating information. State which you consider to be the most effective.

The information was very important in our life. We have been surrounded by the information since we were born. Information can be interpreted as massage. There are so many media that brought the information into us, for instance; television, radio, film, theatre, books, comics etc. I do believe every media has each advantages and disadvantages.

There are some advantages from television, radio, film that can be explained. These electronic media were very effective for share the information. The massages that come from media electronic were often very powerful effected the people. People often very fast take in the information from television and film. Similar with the radio, television, and film, theatre was also very touchable to share the culture and education through the live shows. In addition book and comics are very effective to spread the good ideas. Books also played the essential role in human history. While the books provide the massages from the sentences and story, the comics send the massages trough the picture and animation.     

On the other hand, television, radio, and film have some disadvantages. Some programs that provide in television were very hypnotizing and it can drain productive time when people spent a lot of time to watch. Hence it very powerful to effecting people, so many violence and criminal act have also resulted from the television and films. Even so some books and comics have some disadvantages. We need to be focus to read the book for hours. Several comics only give the entertainment instead the useful information.

In conclusion, in my opinion the television, radio, and film are most effective because the massage could be taken easily than the books and comics.
