As a senior high school student, I am very busy with my studies. Although I am very fond of watching television, I can only spend an hour after dinner on my hobby. Of all the TV programs, I like the news and documentaries best.

The news programs shown on all TV channels at 7:00 p.m. help me to know almost everything about different places in our country and important events happening all over the world. Through these programs, I can also know about the main national and international sporting events.

The documentary programs at weekends are my favorites. By watching them, I can learn a great deal about human civilizations, the wonders of nature and the amazing inventions and discoveries of great people in the world.

Watching television is my hobby. I cannot imagine a day in my life without watching it.
