Want to Be 100? Listen to These 5 Centenarians(百岁老人)

Five neighbors at a central Missouri retirement community who are all centenarians get asked all the time: "How did you live to be 100?."
If you want to live to 100 or more, this rare group of five golden girls says the key to longevity (长寿)is working hard at a job you love and taking care of your body while you're at it.
Even though an estimated 70,000 people in the country are currently at the century mark or be yond in age, it is unusual to find five 100-year-olds living in one place.
The average life-span(寿命) of Americans is about two or three years short of an 80th birthday party. And most people don't want to cut out coffee, soda, alcohol, cigarettes, and eat healthy food.
"People tell me all the time, 'I don't want to live to be 100,'" said Mildred Leaver, who turned 100 in June.
"I think that's just sad. Aging is attitude and I don't feel old," said Leaver, a former educator who still drives her Buick around town.
It doesn't take long to see that Leaver and her neighbors Mildred Harris, Grace Wolfsan, Gladys Stuart and Viola Semas, have a lot more in common than their longevity and lifelong healthy habits. All are 100 except Stuart, who is 101.
Even though their sight and hearing aren't what they used to be, they've all avoided illnesses that many elderly people are stricken with. It's been 50 years since Leaver beat cancer for the first and only time.
The common thread that connects these women is the decades of service to jobs each loved as a farmer, designer, school principal, bookkeeper and secretary. In the early years of their lives, gain fully employed women like them were just as rare as 100-year-olds are today.
单选题 Currently about 70,000 people are aged 100 or above in America.
【正确答案】 A
【答案解析】[解析] 短文第三段说,虽然估计在这个国家中有七万人现在年龄达到100岁或者100岁以上,从上下文提到的密苏里州及美国人平均寿命可知这个国家指的是美国。故本题是正确的。
单选题 It is not hard to find five 100-year-olds living in one place in America.
【正确答案】 B
【答案解析】[解析] 第三段后半部分说,在一个地方要找到5个百岁老人住在一起,这太稀少了。故本题是错误的。
单选题 None of the five centenarians have any children.
【正确答案】 C
【答案解析】[解析] 题干说“这5位百岁老人都没有孩子”。从句意来看,问题句内容涉及文章中细节信息。通读全文,发现文章只提到了5位百岁老人及他们的养生之道,但根本没有提到他们的孩子(children,son,daughter这样的词根本没有在文章中出现),因此判断问题句的信息在文章中没有提到。
单选题 The average life-span of Americans is 80 years.
【正确答案】 B
【答案解析】[解析] 短文第四段说The average life-span of Americans is about two or three years short of an 80th birthday party.美国人的平均寿命是距离80岁生日还差2到3岁。
单选题 Leaver feels sad about her old age.
【正确答案】 B
【答案解析】[解析] 题干说“Leaver对自己年事已高而感到悲哀”。从句意来看,该问题句涉及到文章中具体细节信息。答案相关句在第六段,Leaver说“think that's just sad”。但代词that指代的是前面那句话“People tell me all the time,'I don't want to live to be 100,'”而且接下来Leaver说"I think that's just sad.Aging is attitude and I don't feel old,”因此判断该问题句是错误的。
单选题 Leaver was stricken with cancer 50 years ago.
【正确答案】 A
【答案解析】[解析] 短文倒数第二段最后一句说,Leaver 50年前战胜了癌症,这是第一次也是唯一的一次,可见本句是正确的。
单选题 The five centenarians live in a very friendly community.
【正确答案】 C
【答案解析】[解析] 尽管我们可以推测这5位百岁老人之间可能是非常友好的(friendly),但整个社区(community)是否非常友好并没有提到。
