The television has been an important part of many families’ life. Many children like to sit in front of the television instead of doing something else. When many experts (专家) say that television is bad for children, some believe that television can really have a good effect on a child’s life, if it is used properly.

There are many television programmes that both provide fun and education. Spending some time on these types of programmes is good for your child’s development. The television can be more efficient at teaching a child certain (某种) tasks.

Parents can also use the television to help children read. After watching an educational programme, your child may become more interested in a topic. Use that interest to drive your child toward reading.

The television can also help to make a family closer. After a programme ends, you can start a decision about it. This can help encourage a healthy family.

The television can introduce your child to new cultures. This can help your child learn a lot from them.

The television can also help build a bridge for difficult communication between parents and children. If a child refuses to talk about a topic with his or her parents, he or she is willing to talk about it with his or her parents after watching the programme about the topic. This is an example of television’s role as a bridge to tough communication.

The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?

The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.

The energy in food is in the form of three kinds of chemical materials—carbohydrate（碳水化合物）, protein（蛋白质） and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.

(P= protein      C= carbohydrate    F=fat)
