问题补充：
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 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(现在), the world faces two problems. People in some places, for example, in Africa, are not full. Many people are eating junk food. Its bad for peoples health. So its our duty to make everyone full and make everyone healthy.

答案：
(答案→)C
解析：世界上有许多种类的食物。科学家们了解他们。他们说，有一些食物，人们必须每天吃。例如，人们要多吃一些绿色和黄色蔬菜。我们不应该吃太多的肉。人们还需要吃一些水果，面包和米饭。当然，我们的身体需要一些水和牛奶。科学家们说，在不同的国家和不同的地方吃不同种类的食物的人。他们做不同的食物。在不同的时代，人们吃的不同。在一个地方，人们吃一次或两次一天。但在另一个地方，人们吃三或四次。科学家们说，什么时间吃和吃多少次都不重要。我们吃的内容是最重要的。现在，世界面临着两个问题。有些地方的人，例如，在非洲，是吃不饱的。还有许多人吃垃圾食品。它对人的健康有害。所以让每个人都吃饱和让每个人都健康是我们的责任。
