Last week I noticed Jack coughing on our math class. See this, I offered to take him to a clinic. There the doctor asked Jack how he had coughed sometimes for long time. Jack nodded his head immediate. The doctor then wrote a prescription with instruction on how to take the Chinese medicine. When Jack tasted the medicine, he almost brings it up. I comforted him with an old saying “Good medicine for health tastes bitter to the mouth”. Jack managed to swallow them unwillingly. But when he had recovered three days later, he felt amazing at the effect of the Chinese medicine.

My interest in Chinese food started years ago, when I was a young reporter for the Washington Post. Our office wasn’t far from Chinatown, 1. I found some very good Chinese restaurants.
That was the first time that I 2. (notice) the fresh taste of the meat and vegetables of Chinese food. When I learned more about the food, I began to understand why 3. has this special feature.
Many years ago, China had 4. energy crisis because it lost much of its wood due to over population and poor management of its forests. This 5. (lose) was very bad for the country, of course, but it turned out to be very good for the food. Wood became very expensive and hard to get, so the Chinese had to either find a substitute for their 6. (value) wood, or learn how to use it better. There weren’t any substitutes so people found ways to economize.
In order to economize in cooking, they had to use very little wood. So they started cutting their meat and vegetables 7. small pieces before they put them in the hot oil. That way, the food cooked 8. (fast) and they saved more fuel. The food 9. (prepare) in this way kept its fresh flavor — and it’s this flavor 10. attracts people from other countries to the art of Chinese cooking.

Researchers in the United States say eating less can slow the aging process of cells in the body. The researchers studied mice, not people.
1. One group was able to eat as much as it wanted. The other animals in the other group were limited to eat. Their diet had 35 percent fewer calories than the first group of mice.
The mice with the diet restrictions (限制) were more energetic and suffered fewer diseases. They were not just living longer, they seemed to stay younger for a longer period of time. When you restrict calories (in mice), there is a direct increase in lifespan—the average age of the animal.2.
But how? The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes (核糖体). Ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down.3. This, in turn, keeps cells and the entire body functioning well.
Earlier studies have suggested a link between calorie restrictions and slowed aging.4.
Calorie restriction as a way to slow aging has not been tested in humans. But the main finding for people is the importance of taking care of our bodies.5. And this may help us make better decisions about what we eat.
A. The less we eat, the healthier we are.
B. Researchers studied two groups of mice.C. This finding is good news if you are a mouse.
D. This gives the cells more time to repair themselves.
E. The findings help to explain how exactly our bodies age.
F. However, this is first to show how the ribosomes can influence aging.
G. Calorie restriction caused real biochemical changes that slowed down the rate of aging.
