Sometimes, people are not clear about what kind of food is healthy, and what kind of food may do harm to our health. The USDA has prepared a food guide to help people learn about which kind of food is the healthiest to eat. The food guide describes six main food groups: meat (like fish and chicken), dairy (like milk and cheese), grains (like bread and rice), fruit, and vegetables. The last group is fats and sweets. The USDA also suggests (建议) how much of each food group is healthy to eat daily. Though this guide was prepared by the US government, it is very useful for people all over the world. As a result of years of study, we know that too much animal fat is bad for our health. For example, Americans eat a lot of meat and only a small amount (量) of grains, fruit and vegetables. Because of the way they eat, they have a high rate (率) of cancer (癌症) and heart disease. In Japan, people eat large amounts of grains and very little meat. The Japanese also have a very low rate of cancer and heart disease. The Japanese live longer than anyone else in the world. However, when Japanese people move to the US, the rate of heart disease and cancer goes up as their eating habit changes. And as hamburgers, ice creams and other high-fat foods become popular in Japan, the rate of heart disease and cancer is going up there as well. People are also eating more meat and dairy food in other countries, in which the disease rate is going up alone with the change of the way people eat. Doctors everywhere suggest people eat more grains, fruit and vegetables and less meat and dairy food. Eating healthily is important for children as well as their parents. When parents have poor eating habits, their children usually do, too. After all, children eat the same way as their parents. When parents eat healthy food, the children will learn to enjoy it, too. Then they will develop good eating habits. Doctors suggest parents give their children healthier food such as fruit, vegetables and juice. Everyone wants to live a long, healthy life. We know that the food we eat affects (影响) us in different ways. For example, doctors believe that fruit and vegetables can really protect people from many different diseases. On the other hand, animal fat can cause (引起) diseases. We can change our eating habits now and enjoy many years of healthy living. |

Some people believe that schools will no longer be necessary in the near future. They say that because of the Internet and other new technology, there is no longer any need for school buildings, classes or teachers. Perhaps this will be true one day, but if the world has no schools, I can"t imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school that is linked (链接) to libraries,museums, science centres, labs and even companies. Technological companies should create (创造) learning programs for schools. Scientists could give talks through the Internet. TV networks and local (本地的) stations could develop programs about things students are studying in school. Labs could set up Web sites to show new technology so students could see it on the Internet. Is this a dream? No. There are already many cities where this is beginning to happen. Here the whole city is linked to the Internet, and learning can take place at home, at school,and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new kind of school change the usual way of learning? It is too early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will all learn something from the Internet. |

Typhoons are some of the worst storms, usually around the Pacific Ocean and the South China Sea. Most happen in July, August and September. How does a typhoon happen? When lots of sea water gets hot in the summer sun, it evaporates (蒸发) into the air. This makes the air hotter. When the air gets warm enough, it starts to move higher up into the sky. Then, cooler air around it rushes in. It fills the space that is left. After the air gets warmer, it starts to move quickly, making wind. The wind goes in circles, and it keeps moving higher in the sky. The warmer the air gets, the quicker the wind moves. And when the wind moves faster than 30 meters a second, a typhoon begins.A typhoon has two parts, One is called the “eye”. In the eye, the wind does not move so fast. The other part is the wall of clouds around the eye. This is where the strongest wind and hardest rains are. Typhoons are very dangerous. In 2004, Typhoon Yunna killed 164 people in Zhejiang, and 24 people were missing. In May 2006, Typhoon Pearl hit Guangdong and Fujian, and thousands of houses were damaged.What to do when a typhoon hits: ● Stay inside, close all the windows and stay away from them. ● Try to bring all of your things inside. Strong winds could even blow away your bikes! ● Listen to the radio or TV for important information. ● If you’re told to go to a safer place, do so right away. |
