Ⅰ. 阅读理解
Essentially, everyne has tw ages: a chrnlgical (按时间计算的) age, hw ld the calendar says yu are, and a bilgical age, basically the age at which yur bdy functins as it cmpares t average fitness r health levels.
“Chrnlgical age isn't hw ld we really are. It's merely a number，” said Prfessr David Sinclair at Harvard University. “It is bilgical age that determines ur health and ultimately ur lifespan (寿命). We all age bilgically at different rates accrding t ur genes, what we eat, hw much we exercise, and what envirnment we live in. Bilgical age is the number f candles we really shuld be blwing ut. In the future, with advances in ur ability t cntrl bilgical age, we may have even fewer candles n ur birthday cake than the previus ne．”
T calculate bilgical age, Prfessr Levine at Yale University identified nine bi­markers that seemed t be the mst influential n lifespan by a simple bld test. The numbers f thse markers, such as bld sugar and immune measures, can be put int the cmputer, and the algrithm (算法) des the rest.
Perhaps what's mst imprtant here is that these measures can be changed. Dctrs can take this infrmatin and help patients make changes t lifestyle, and hpefully take steps t imprve their bilgical cnditins. “I think the mst exciting thing abut this research is that these things aren't set in stne，” Levine said. “Peple can be given the infrmatin earlier and take steps t imprve their health befre it's t late.”
Levine even entered her wn numbers int the algrithm. She was surprised by the results. “I always cnsidered myself a very healthy persn. I'm physically active; I eat what I cnsider a fairly healthy diet. But I did nt find my results t be as gd as I had hped they wuld be. It was a wake­up call，” she said.
Levine is wrking with a grup t prvide access t the algrithm nline s that anyne can calculate their bilgical age, identify ptential risks and take steps t imprve their wn health in the lng run. “N ne wants t live an extremely lng life with a lt f chrnic diseases，” Levine said. “By delaying the develpment f mental and physical functining prblems, peple can still be engaged in sciety in their senir years. That is the ideal we shuld be pursuing.”
1. Bilgical age depends n ________．
A. what the calendar says abut ur age
B. when we start t take utdr exercise
C. whether we can adapt urselves t the envirnment
D. hw well ur bdy wrks cmpared with ur peers'
2. What des the authr mean by saying the underlined part in Paragraph 2?
A. We are chrnlgically lder than last year.
B. We might be less happy than the previus year.
C. We dn't have t celebrate ur birthday every year.
D. We may be bilgically yunger than the year befre.
3. What des the authr want t tell us by Levine's example in Paragraph 5?
A. It is necessary t change ur diet regularly.
B. The algrithm can reveal ur ptential health prblems.
C. Waking up early in the mrning is gd fr ur fitness.
D. The test results may give us wrng infrmatin.
4. Which f the fllwing wuld be the best title fr the passage?
A. Bi­markers Can Make Us Yunger
B. Chrnlgical Age and Bilgical Age
C. Old Peple Can Still Be Engaged in Sciety
D. Bilgical Age Can Lag Behind r Exceed Chrnlgical
Age
【语篇解读】本文是一篇说明文。我们的生理年龄可能会因为我们的基因、饮食、运动量以及所处的环境不同，而落后于或者超过实际年龄。
1. D 细节理解题。根据第一段中的“a bilgical age, basically the age at which yur bdy functins as it cmpares t average fitness r health levels”可知，生物年龄取决于我们的身体与同龄人相比有多好。故选D。
2. D 推理判断题。根据第二段中的“In the future, with advances in ur ability t cntrl bilgical age, we may have even fewer candles n ur birthday cake than the previus ne．”和常识可知，过生日插生日蜡烛指的是生理年龄的增长，由此判断出，第二段画线部分是指我们的生理年龄可能比前一年年轻。故选D。
3. B 推理判断题。根据第五段中的“She was surprised by the results.”和“But I did nt find my results t be as gd as I had hped they wuld be.”可推知，作者通过Levine的例子告诉我们这个算法可以揭示我们潜在的健康问题。故选B。
4. D 标题归纳题。通读全文以及第二段中的“Chrnlgical age isn't hw ld we really are. It's merely a number”和“We all age bilgically at different rates accrding t ur genes, what we eat, hw much we exercise, and what envirnment we live in.”可知，我们的生理年龄可能会因为我们的基因、饮食、运动量以及所处的环境不同而落后于或者超过实际年龄。故选D。
