Of all the foods we know, fruit is one of the most healthful. It is also one of the most tasty foods. Almost everyone enjoys fruit. Fruit is grown in almost every part of the world. There are hundreds of different kinds of fruits. And there are thousands of different varieties. In the United States alone, there are several hundred types of apples.
In general, though, there are three separate groups. There are tropical fruits. These are most important. In this group, we have bananas and pineapples. They are shipped from tropical countries and are eaten all over the world.
Next come the subtropical fruits. The most important of these are the citrus fruits. Oranges, tangerines, limes, and grapefruit are favorites. Other fruits in this class are figs, dates, and olives.
The last group comes from the temperate zone. In this group are pears, apples, grapes, and plums. Many kinds of berries fit this group, too.
Fruits are very important to the human diet. Besides being tasty, they provide important acids, salts, and vitamins. Also, they are easy to digest. Nutrition experts say that the more fruit people eat, the healthier they become.
Down through the centuries fruit has played a part in tales and history. In a Greek myth, Hercules sent Atlas to pick "golden apples" to pay for a crime. Today we believe these golden apples were oranges. During the 1700's, British ships began to carry limes. It was found that sailors who drank the lime juice did not get sick. Since that time, British sailors have been called "limeys."
The peach also has an exciting history. It has been a world traveler. Its journey began many, many centuries ago. Peaches were first grown in China. From China, traders of long ago carried peach trees to Persia. From there, Alexander the Great brought the fruit to Europe. From Europe, Spanish ships carried peaches to the New World.
Through the years, fruit trees and plants have been improved. Today's fruits are bigger. They also taste better. Different kinds of fruits are often being bred. We now have fruit that can travel to all parts of the world and still stay fresh. Even after traveling for some time, these new fruits keep the vitamins and minerals that are so good for our diet. Fruit will always be prized as a basic food that now can be enjoyed the whole year round.
Which of the following is NOT true according to the text？
Malnutrition (营养不良)
A new World Bank report warns that children who don't get enough good food in the first two years of life suffer lasting damage. They may be underdeveloped or underweight. They may suffer from poor health or limited intelligence. In addition, poorly nourished children are more likely to drop out of school and earn less money as adults.
The report notes that too little food is not the only cause of poor nutrition. Many children who live in homes with plenty of foods utter for other reasons. For example, the study says that mothers often fail to give their newly born babies their first breast milk. This milk-like substance is called colostrum. It is full of nutrients that improve a baby's ability to fight infections and disease.
The study also links malnutrition to economic growth in poor countries. A lack of nutrition in early children can cost developing nations up to three percent of their yearly earnings. Many of these same countries have economies that are growing at a rate of two or three percent yearly. The study suggests that poor countries could possibly double their economic growth if they improved nutrition.
Africa and South Asia are affected the most by poor nutrition. The study says about half of all children in India do not get enough good food. The World Bank study also notes that rates of malnutrition in South Asia are almost double those in central and southern Africa. Other parts of world are also severely affected, including Indonesia, Uzbekistan, Yemen, Guatemala and Peru.
The study recommends that developing countries change their policies to deal with malnutrition. Instead of directly providing food, the study suggests educational programs in health care.
World Bank nutrition specialist Meera Shekar said the period of life between pregnancy and two years was extremely important. Governments with limited resources should take direct action to improve nutrition for children during this period.

听力原文：W: Nine out of ten parents smack their children according to a report published today. What is your opinion about this report？
M: Well, although nine out of ten parents use smacking as a punishment, half of them feel guilty about using it. The other half do smack their children and think they are right. It seems most parents we talked to smack their children more than once a week and 5% actually smack their children every day.
W: The report suggests that parents should make more efforts to understand their children and that smacking isn't always the best solution if children are naughty.
M: Yes, parents should try harder to understand how their children feel when they react in certain ways. For example they might be jealous of a new baby brother or a sister or they might feel insecure. Any number of things might make the child react badly.
W: So in those kinds of situations it would be better not to smack children？
M: Yes, obviously because when a child's behaving badly, it needs love and attention, not anger and violence. I think parents should think really carefully before they smack their children.
W: Maybe parents should find an opportunity to communicate with their children.
M: That's right.
