Dear Mariby22,
In order to encourage your students to see both sides of an argument, you could ask them to begin:
"The Internet, (The family), has positive and negative influences in our lives.
On the positive side, firstly ... , secondly ... , thirdly ..."
"By contrast, on the negative side, firstly ..., secondly ... , thirdly ... "
I suggest that you specifically say to the student: "Don �t begin your answer with �The Internet, (The family), plays an important role in our life! � please!" Forbid the phrase!
You could say: "Try to begin with different introductions, for example .... .... ..."
I agree with the other writers, who indicate that the manner of asking the question itself, (by the Teacher), will alter the manner of the response, and will tend to �kill off � the boring introduction used by Students. The question will �channel � the answer away from the response: "XYZ plays an important role in our life!"
"Can you tell me 3 bad effects of the Internet?"
"The Internet has some bad effects --- can you list several of its disadvantages, please?"
"What do you dislike about the Internet?"
"If you have ever had a bad experience at home, can you describe it , please?"
"The family plays an important role in our life, but are there times when it is a problem?"
"In your opinion, when does the family cease to be important?"
The other writers have given some excellent suggestions. They may not agree with my suggestions.
I hope that I have helped you.
