I often quarrel with my mother over if I can watch TV after school. She holds the view that high school students has to make full use of every minute to work hard at their lesson. It seems to her that once I am allowed to do that, I’ll be unable to control myself and forgot all about my study. I also thinks watching TV is bad for my eyes. But I really can’t accept her ideas. In my opinion, watching TV can make my mind to have a rest after a day’s hardly work. Beside, it is important for us to know what has happened home and abroad. Thus, we shouldn’t be forbidding to watch TV.

On-line voting becomes increasing popular, and many competitions get people involve in it. It is beneficial to some people, so it puts others into a dilemma over whether vote or not.
In my opinion, on-line voting is a inseparable part of modern life and should be welcomed，since it is a way to participate in public life. There is no difference between on-line voting and ordinary voting events, in what candidates go around to seek support. In addition, the Internet makes surveying and voting easier and more convenient, regardless of time and space. Furthermore, voting on the Internet make instant feedback possible.
To be honest, voters sometimes feel annoyed, not because of they hate voting, but because we are divided between emotion and fairness. Things will turn for the better if we can work out some participations rules for people to obey. Therefore, I hold attitude towards on-line voting.

With the development of the Internet, more and more people send ecards instead paper ones when an important holiday comes.
Comparing with the traditional cards, ecards are more interested. Besides, it is faster to send an ecard. The next advantage is that there are many web site online in which there are many cards for you to choose from. Final, with the popularity of ecards, more paper is used in making paper cards, that does good to our environment.
In the short, there are many advantages of using ecards. I hoped that sending greetings by using ecards will be accepted by more people, not only the young one.
