Researchers in the United States say eating less can slow the aging process of cells in the body. John Price, a biochemistry professor at Brigham Young University in the U.S. state of Utah, with other researchers studied two groups of mice. One group was able to eat as 16 as it wanted. The researchers controlled what the second group ate. Their diet had 35 percent fewer calories than the first group of mice. Price said the second group of mice was more 17 and had fewer diseases. They were not just living longer. He and his team found that 18 calories slowed aging. The researchers found that fewer calories slow down cells ribosomes (核糖体). Price explained that ribosomes are used to make important proteins (蛋白质). But with fewer calories, they slow down. This gives them more time to 19 themselves. Price used cars to explain this. “Like a car, a ribosome isnt a simple 20 . It needs repairs to change the broken parts. When the glass of the car is broken,” he explained, “you dont need to throw the 21 car away and buy a new one. It costs less to change the glass. ” Price said that because of this, it is 22 to break a whole ribosome when it starts to break down. “Instead, repairing single part of the ribosome makes ribosomes continue producing high quality proteins. This top quality production keeps cells and the whole body 23 well,” he added. Earlier studies have suggested a connection between calorie reduction and slowed aging. However, this is first to show how the ribosomes can 24 aging. Price said the findings help to explain 25 exact our bodies ages are. And this may help us make more wise decisions about what we eat.16. A. more B. much C. little D. less17. A. energetic B. clever C. special D. careful 18.
