Most children like to watch TV. It's very interesting. By(通过) watching TV they can see and learn a lot and know many things about their country and the world. Of course, they can also learn over the radio. But they can learn better and more easily with TV. Why? Because they can hear and watch at the same time. But they can't see anything over the radio.
TV helps to open children's eyes. TV helps to open their minds, too. They learn newer and better ways of doing things. They may find the world is now smaller than before.
Many children watch TV only on Saturday or Sunday evening. They are always busy with their lessons. But a few children watch TV every night. They go to bed very late. They can't have a good rest. How about you, my young friend?
I am John. I always get up late at the weekend. At about 9:30 am, I have breakfast. After breakfast, I start doing my homework. We have lunch at about 12:00, and then I watch TV or have a rest. I like reading and I often read some interesting books in the afternoon. I like sports, too. Sometimes I play football or basketball with my friends at school. My school is near my home, so I can walk there. Every weekend, my father takes me to a restaurant for a big dinner. I can enjoy lots of nice food. I like my weekend.

This is me!
Mr. and Mrs. Su don't often go out in the evening, but today they go out for a walk after supper. They go to the park and have a good time there. On their way home, Mr. Su says to Mr. Su, "Look! A woman is running in the street and a man is running after her." Mr. Su says, "What's the matter? Let's go and help her."
Now the woman gets near them. Mr. Su asks, "Shall we help you?" "No, thank you," the woman says, "My husband（丈夫） and I are running home, and the slower (较慢的) one does the housework."
