There are many kinds of food in the world. Scientists learn a lot about them. They say that there are some kinds of food people must eat every day. For example, people must eat some green and yellow vegetables. We shouldn’t eat too much meat. People also need to eat some fruits, bread and rice. Of course our bodies need some water and milk.
Scientists say people in different countries and different places eat different kinds of food. They cook food in different ways. Different people eat at different times. In one place, people eat once or twice a day. But in another place, people eat three or four times. The scientists say when to eat and how many times to eat are not important. What we eat is the most important thing.
Nowadays, the world faces two problems. People in some places, for example, in Africa, are not full. Many people are eating junk food. It’s bad for people’s health. So it’s our duty to make everyone full and make everyone healthy.

Most children don't enjoy doing housework. They like playing computer games instead of cleaning the rooms. But in Australia, Jim and Robert's mother, Mrs. Black, has good and proper methods to get their children to do housework.
Here is an example.
“Mom, have you worked out next week's housework? Let Jim and me choose the cards. I can't wait. It's fun!”
When Robert shouted out, his mother had already put all the cards on their big table. On the cards, there are some words like these, “sweep the floor, clean your bedroom, help mom cook, wash vegetables, make beds, feed the fish, cut the wood, clean the bathroom” and many others. Jim and Robert chose two cards for each day from Monday to Friday. Then they would hang them on the weekday task board. Jim likes to clean the bathroom best, so he picked up the card “clean the bathroom” first. Robert loves to make the bed so he picked up his favorite card. Jim again picked up “wash vegetables” and Robert chose “feed the fish”. Soon the two boys were happy to take away all the cards.
To help the children do housework, their mother thought hard and thought up this idea. Of course, their parents did the housework on the weekends and left Jim and Robert two days free.
