　　Passage Two

　　文章二

　　In recent years, the death rate among American centenarians— people who have lived to age 100 or older— has decreased, dropping 14 percent for women and 20 percent for men from 2008 to 2014.

　　近年来，美国百岁老人(百岁及以上的人)的死亡率下降了，从2008年到2014年，女性下降了14%，男性下降了20%。

　　The leading causes of death in this age group are also changing.

　　这个年龄段的主要死亡原因也在变化。

　　In 2000, the top five causes of death for centenarians were heart disease, stroke, flu, cancer and Alzheimer's disease.

　　2000年，百岁老人的五大死因是心脏病，中风，流感，癌症和阿尔茨海默症。

　　But by 2014, the death rate from Alzheimer's disease for this age group had more than doubled— increasing from 3.8 percent to 8.5 percent— making the progressive brain disease the second leading cause of death for centenarians.

　　但到2014年，这一年龄段的阿尔茨海默症死亡率已经从3.8%增加到了8.5%，使得渐近脑疾病成为百岁老人死亡的第二大原因。

　　One reason for the rise in deaths from Alzheimer's disease in this group may be that developing this condition remains possible even after people beat the odds of dying from other diseases such as cancer.

　　在这个组中阿尔茨海默症死亡人数上升的一个原因可能是即使在人们罹患其他疾病如癌症的可能性之后，发展到这种病症也是可能的。

　　People physically fit enough to survive over 100 years ultimately give in to diseases such as Alzheimer's which affects the mind and cognitive function.

　　活过100岁的身体足够健康的人，最终会因阿尔茨海默病等疾病导致影响心理和认知功能。

　　In other words, it appears that their minds give out before their bodies do.

　　换句话说，似乎他们的心智比身体先失灵。

　　On the other hand, the death rate from flu dropped from 7.4 percent in 2000 to 4.1 percent in 2014.

　　另一方面，流感的死亡率则从2000年的7.4%下降到2014年的4.1%。

　　That pushed flu from the third leading cause of death to the fifth.

　　这将流感从第三大死因推向了第五大。

　　Overall, the total number of centenarians is going up.

　　总的来说，百岁老人的总数正在上升。

　　In 2014, there were 72,197 centenarians, compared to 50,281 in 2000.

　　2014年，有72197名百岁老人，而2000年有50281人。

　　But because this population is getting larger, the number of deaths in this group is also increasing— 18,434 centenarians died in 2000, whereas 25,914 died in 2014.

　　但由于这个群体越来越大，本组死亡的人数也在增长- 18，434名百岁老人在2000年去世，而在2014年去世的25914人。
