16、One possible version:

At present, short messages are widely involved in various TV programs．People react to them in different ways．

Defenders hold the view that short messages offer the audiences more chances to participate in the live programs．In this way, the mass media benefit a lot from them．On the other hand, they appeal to the need of the young people．

Critics accuse that if the short messages are out of control, we cannot ensure the taste of the programs．What’s more, the expenses may make audiences feel bad．To make matters worse, some adolescents are so addicted to them that too much time and energy are wasted．

As far as I am concerned, the short message is typical of information technology, but it is a powerful tool that needs to be used with care．
