Why do you think people who live in some hot countries eat very spicy(辛辣的)food? Is it because the spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked hot food，or is there some connection between spices and healthy food?
Researchers from Cornell University think that it is because spice plants have some important chemicals(化学物质)．These chemicals can kill bacteria(细菌)which spoil food．
“Most common spices can kill 75 to 100 percent of the bacteria in food，”explains one of the scientists．The bacteria grow more easily and spoil food more quickly at higher temperatures．For this reason，it is more difficult to keep food from spoiling in hot climates，
Do you like your food spicy? Your answer probably tells something about the country you come from．If you like spicy food，it is possible that hundreds of years ago，when there were no fridges，people in your country started using spices to keep the food from spoiling．The traditional spicy dishes helped those people to live longer，healthier lives．Today，in a time of fridges，the spices just make the food taste good．
【小题1】The chemicals in spices keep food from spoiling by_________．

Trees are useful to man in three important ways.

The first important way is that they provide(提供) us food, wood and other products(产品). Trees provide food not only for man, but also for many animals. 61. Without trees, many animals cannot live on the earth.

The second important way is that trees give us shade(阴凉). On a hot summer day, people hope to have a rest under the tree after they have a long walk.

The third important way is that trees help to prevent droughts(干旱) and floods(洪水). However, in many parts of the world, man doesn’t know about the third way. They cut trees in large numbers. In the end they will find that they lose one of their best friends.

Chinese are very generous in educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the United States and Australia. They also want their children to take extra-course activities such as musical instrument learning or ballet classes, or other classes. They think these will give them a good future. The Chinese believe that the more expensive an education is, the better it is. So parents will spend much unreasonable money on education. Even poor parents will buy a computer for their son or daughter.

However, most parents don’t understand that the best early education they can give their children is usually very cheap.

Parents can see that their children are very good in some areas while poor in others. Parents can also see some children are good at these skills and others do well in others. Most parents don’t realize that today’s children lack self-respect and self-confidence.

The problem is that parents are only educating their children on how to take tests and how to study well, but parents are not teaching them the most important skills that they need are to be confident, happy and clever.

Parents can achieve this by teaching skills like cooking, sewing and doing other housework. Teaching a child to cook will improve many of the skills that he will need later in life. Cooking needs patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and lots of self-confidence.

Some old machines, such as a broken radio or TV set that you give your child to play with, will make him curious(好奇的) and improve his interest. He will spend hours looking at them, trying to fix them. Your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.
