Ⅰ. 阅读理解

Essentially, everyone has two ages: a chronological (按时间计算的) age, how old the calendar says you are, and a biological age, basically the age at which your body functions as it compares to average fitness or health levels.

“Chronological age isn't how old we really are. It's merely a number，” said Professor David Sinclair at Harvard University. “It is biological age that determines our health and ultimately our lifespan (寿命). We all age biologically at different rates according to our genes, what we eat, how much we exercise, and what environment we live in. Biological age is the number of candles we really should be blowing out. In the future, with advances in our ability to control biological age, we may have even fewer candles on our birthday cake than the previous one．”

To calculate biological age, Professor Levine at Yale University identified nine bio­markers that seemed to be the most influential on lifespan by a simple blood test. The numbers of those markers, such as blood sugar and immune measures, can be put into the computer, and the algorithm (算法) does the rest.

Perhaps what's most important here is that these measures can be changed. Doctors can take this information and help patients make changes to lifestyle, and hopefully take steps to improve their biological conditions. “I think the most exciting thing about this research is that these things aren't set in stone，” Levine said. “People can be given the information earlier and take steps to improve their health before it's too late.”

Levine even entered her own numbers into the algorithm. She was surprised by the results. “I always considered myself a very healthy person. I'm physically active; I eat what I consider a fairly healthy diet. But I did not find my results to be as good as I had hoped they would be. It was a wake­up call，” she said.

Levine is working with a group to provide access to the algorithm online so that anyone can calculate their biological age, identify potential risks and take steps to improve their own health in the long run. “No one wants to live an extremely long life with a lot of chronic diseases，” Levine said. “By delaying the development of mental and physical functioning problems, people can still be engaged in society in their senior years. That is the ideal we should be pursuing.”

1. Biological age depends on ________．

A. what the calendar says about our age

B. when we start to take outdoor exercise

C. whether we can adapt ourselves to the environment

D. how well our body works compared with our peers'

2. What does the author mean by saying the underlined part in Paragraph 2?

A. We are chronologically older than last year.

B. We might be less happy than the previous year.

C. We don't have to celebrate our birthday every year.

D. We may be biologically younger than the year before.

3. What does the author want to tell us by Levine's example in Paragraph 5?

A. It is necessary to change our diet regularly.

B. The algorithm can reveal our potential health problems.

C. Waking up early in the morning is good for our fitness.

D. The test results may give us wrong information.

4. Which of the following would be the best title for the passage?

A. Bio­markers Can Make Us Younger

B. Chronological Age and Biological Age

C. Old People Can Still Be Engaged in Society

D. Biological Age Can Lag Behind or Exceed Chronological

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 biological age, basically the age at which your body functions as it compares to average fitness or 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 our ability to control biological age, we may have even fewer candles on our birthday cake than the previous one．”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 not find my results to be as good as I had hoped they would 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“Chronological age isn't how old we really are. It's merely a number”和“We all age biologically at different rates according to our genes, what we eat, how much we exercise, and what environment 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。

【参考范文】

Dear Jim，

I am very glad to have received your email and I know that you'll take part in the “Studying in China” Speech Contest. I'd like to give you some practical suggestions.

I recommend that you talk about the courses on traditional Chinese culture you've attended. The major reason is that they introduce the real treasure in human history.

To do it well, I think you should choose impressive examples to gain the recognition of the judges. Moreover, you have to practise your spoken Chinese to express yourself more clearly and fluently. I really hope my advice will be helpful. Wish you a great success.

Yours，

Li Hua
