These days people are using various social networking sites like Facebook, twitter, etc. Some social networking sites ban the opening of an account by children below 18 years. What is your opinion about it? Explain with too examples.
Answer:
Social networking sites are exposed to everything. So, they should be used cautiously and wisely. As children are not mature enough to understand everything properly.

Something To Do
Question 1.
Describe the pleasure that you get when you receive a letter from loved one. Does an e-mail give you similar pleasure?
Answer:
Last Saturday I got a letter from grandfather, who lives at my native place in a village. I can’t describe my pleasure in words. This was the second time that he had written to me. The lovely words that he uses show how deeply he loves me and my parents. I read each and every word two-three times. The more I read, the more I get pleasure. My grandfather is so nice; so affectionate. I really adore him. I don’t think, an e-mail from him will give me a similar pleasure.
Question 2.
Discuss with your parents and teachers and find out the problems that have been created by instant communication.
Answer:
Following are few of the problems created by instant communication:
- Instant messages provide you with very little in terms of security. Your message can be heard and viewed by others as well.
- Instant communication can distract you from the task you are performing or concentrating on.
- Instant communication gives very little time to think and react and that can be dangerous at some instances.
Question 3.
Have a class debate on the topic children should be allowed to bring mobiles to school.
Answer:
Small children should not be allowed to bring mobiles to school. They are too small to take care of mobiles. Even if they take good care of them, they will be diverted from their studies. Having a mobile phone in their pocket, I don’t think they will be able to concentrate on their studies.
Question 4.

Answer:
- I would not talk loudly on my mobile phone.
