10、选出最佳选项。21（6分）If you want to slow aging, you might want to eat less. This finding is good news-if you were a mouse. The researchers studied mice, not people.John Price and other researchers studied two groups of mice. One group was able to eat as much as it wanted. The researchers limited what the mi
11、ce in the other group ate. Their diet had 35 percent fewer calories than the first group of mice.Price says the mice with the diet restrictions were more energetic and suffered fewer disease. They were not just living longer but seemed to stay younger for a longer period of time.The researchers foun
12、d that fewer calories slow down a natural mechanism in cells called ribosomes. Price explains that ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down. This gives the cells more time to repair themselves.The researchers say ribosomes use from
13、 10 to 20 percent of the cells energy to make those proteins. Price wrote that because of this, it is impractical to destroy an entire ribosome when it starts to break down. However, repairing individual parts of the ribosome on a regular basis enables ribosomes to continue producing high quality pr
14、oteins for longer than they would otherwise. This top quality production, in turn, keeps cells and the entire body functioning well.Price said, ribosome is a very complex machine, like a car. They need maintenance to replace the parts that wear out the fastest. When tires wear out, he explained, you dont throw the whole car away and buy a new one. It costs less to replace the old tires.Food, he said, isnt just material to be burned-its a signal that tells our body and cells how to respond. Price said the findings help to explain how exactly our bodies age. And this may help us make more educ
