Most of us have three meals a day .We take food for granted(想当然)。And we don't think about it. 1 experts argue a food crisis(危机)is coming. This crisis is going to make us 2 the way we think about food.
Food is in great need3a growing of world population. By 1960, the population was three billion. It doubled to six billion by 1999.By 2050, this planet will need to 4at least nine billion people. As a result, the food prices get higher and higher.
So, what can a 5,crowed world do. One suggestion is to eat6meat. Meat uses more natural resources(资源)than grains(谷物) .It requires more 7to produce one pound of meat than to produce one pound of grain. It also requires between 5 and 10 times more8than vegetables. So, eating less meat will9more land for farming, and it will save water.
To eats less meat, people will need to change their eating habits. That will not be10.Americans, for example, have11 loved meat. In general, they eat twice as much meat as people in other countries. At the same time, in developing countries like China and Brazil, sales of meat have doubled in the last 20 years.12 will double again by 2050.Growing need of meat will 13to put pressure on natural resources.
World population is increasing, resources are becoming fewer, and food prices are rising. Therefore, we need to rethink 14we eat every day. For meat lovers, we don't need to give up meat 15. But we need to eat more grains and less meat.
American Food Habits
Most Americans eat quickly during the day—that is, breakfast and lunch—unless it is a social, business, or family ①occasion. The evening meal, however, is usually ②leisurely and a family time. ③Racing through daytime meals is part of the“American pace”of life, for working time ④is considered ⑤precious. There is also another reason, that others in public eating places are waiting for you to finish, so that they can be served and get back to work within the ⑥allotted time .Each one hurries to make room for the next person.
When we travel from one country to another, we find people have quite different feelings about food. People often feel what they eat is normal, and what other people eat is strange or silly. In most part of Asia, for example, people like rice and meat. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating, like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day.
The sort of meat people like to eat is also different from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealanders eat sheep, but they never eat goat meat. The Japanese don't like to eat sheep meat because of its smell, but they enjoy eating uncooked fish.
People everywhere enjoy eating what they have always eaten, and there is very little we can do to change our eating habits.

Now more and more people in the world are getting fatter③. This troubles them a lot. Experts(专家) say that it has a lot to do with our eating habits.
Our eating habits are very important for good health and a strong body. Most of us like eating sweets and ice cream better than vegetables and rice. Sweets and ice cream are not bad for us if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite①.
It's important for us ② eat our meal in the same period each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges(法官) often decided whether a man was telling the truth by giving him some dry bread. If the man could not swallow(吞) the bread, it meant that he wasn't telling the truth. Because when a man is worried about something, he will have trouble in swallowing anything dry, because he loses his appetite.
bare because wear protect reason
Why do we wear clothes? You may think it is an easy question. But there are many why people wear clothes. In the past, many Europeans and Americans believed that people wore their clothes they didn't want other people to see their bodies. Today we believe that people first started clothes to themselves from the sun, the wind, the rain, the cold and other bad weather.
