Roller Coasters kill 4 people per year

全球每年平均4人死于云霄飛車

Overall, the risk of injury while riding a roller coaster is very low. In the U.S.people take about 900 million rides per year, and only about 1 in 124,000 result in an injury. However, studies show that between the years 1994-2004 there were 40 deaths from roller coasters total, and currently the annual death rate is about 4 per year in the U.S.A.

總的來說，乘坐云霄飛車的危險(xiǎn)性很小。在美國，每年有將近900,000,000人乘坐云霄飛車，平均124,000人中只有1人受傷。但是，研究表明，1994到2004年間，總共有40人死于云霄飛車，死亡率已經(jīng)達(dá)到了每年4人。
