肚臍位置決定你能否成為"飛人" -新概念英語

　　The reason why black people make better sprinters and white people dominate swimming races has been explained by scientists - it's down to their belly buttons.

　　為什么黑人擅長短跑而白人是游泳比賽的常勝將軍?科學(xué)家給出了新解釋，這是由肚臍的位置決定的。

　　The researchers found that the position of the navel in relation to the rest of their body affects athletic ability. This is because the naval is the body's centre of gravity. A higher naval meaning a higher centre of gravity, so your body is pulled forward faster. While a lower navel means a longer torso which makes for a better swimmer.

　　研究人員發(fā)現(xiàn)肚臍在人體的相對位置能夠影響到人的運動能力。因為它是人體的重心所在。肚臍位置高，重心就高，因此向前沖的速度快。反之，肚臍位置低，軀干長，游泳就快。
