A company began 4 a pedometer called the Manpo-kei: “man” meaning 10,000, “po” meaning 5 and “kei” meaning meter. It was hugely 6 and th

3、e number seems to have stuck. Many buyers are appealed by the new device.Since then, studies have 7 the health benefits of 5,000 with 10,000 steps and, not 8 , the higher number is better. But until recently, all the 9 between hadnt been studied. I-Min Lee, a professor of 10 at Harvard Medical Schoo

When they 14 the women up an average of four years and three months later, 504 died. How many steps do you think the people alive had been doing? In fact,

5、 the average number for 15 was only 5,500 but not 10,000. Women who took more than 4,000 steps a 16 were significantly more likely to still be alive than those who did only 2,700 steps. Its surprising that such a small 17 could have consequences for longevity (寿命).However, physical conditions 18 fro

Despite ongoing logging (伐木工作)and recent drought, the Amazon is 5 to perhaps a sixth of the carbon stored in living plants the world over, helping to keep 6 of climate-changing carbon dioxide 7 in the atmosphere. “The Amazon is a particu
