Welcome to Youth Radio, your radio.  Here we're proud to introduce three Amazing Kids.
Gina, who is thirteen years old, got first prize in the "Young Cook of the Year" competition and she wants to write a recipe book for kids. "I want it to be fun to read and easy enough for children to use," she says. Gina learned by watching her father, who's also good at cooking, in the kitchen.  She wants to encourage other children to cook because "everyone needs to eat so it's a skill that will always be useful!"
Seventeen-year-old Brian used to love running until he was hurt in a serious accident three years ago. He lost part of one leg and didn't even expect to walk again. Now he's an athlete who has recently taken part in a long race.  "After my accident I wanted to give up," he says. "But now I'm happy to be alive and able to continue running."
Helen has always been good at science, but she thought it was too difficult to become an inventor. Then she heard about an accident that had happened when a car hit a train in her town.  "That gave me an idea," says the clever sixteen-year-old. It took her over a year to invent a small special machine that tells car .drivers when a train is coming. One company is already interested in selling it, so it may be in he shops soon!
Do you know a child like them? Please e-mail us at amaxingkids@ mail. com and tell us why he or she should be on our radio. Thank you.

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)
【小题1】How many calories are needed to raise the temperature of 5kg of water from 35℃ to 90℃?
