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.

    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.

It's polite to soup noisily and finish the rice in Japan.

It's important     to learn English well.
