1 . As we age, even if we’re healthy, the heart just isn’t as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early 60s. And among people who don’t exercise, the changes can start even sooner.
“Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken,” says Dr. Ben Levine, a heart specialist at the University of Texas. That’s what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven’t been an enthusiastic exerciser, getting in shape now may help improve your aging heart.
Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of nonaerobic (无氧) exercise—balance training and weight training—three times a week. The second group did high-intensity aerobic exercise under the guidance of a trainer for four or more days a week. After two years, the second group saw remarkable improvements in heart health.
“We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts,” says Levine. “And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump (泵送) a lot more blood during exercise.” But the hearts of those who participated in less intense exercise didn’t change, he says.
“The sweet spot in life to start exercising, if you haven’t already, is in late middle age when the heart still has flexibility,” Levine says. “We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all.”
Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine’s findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.

2 . Sometime in the early 1960s, a significant thing happened in Sydney, Australia. The city discovered its harbor. Then, one after another, Sydney discovered lots of things that were just sort of there — broad parks, superb beaches, and a culturally diverse population. But it is the harbor that makes the city.
Andrew Reynolds, a cheerful fellow in his early 30s, pilots Sydney ferryboats for a living. I spent the whole morning shuttling back and forth across the harbor. After our third run Andrew shut down the engine, and we went our separate ways — he for a lunch break, I to explore the city.
“I’ll miss these old boats,” he said as we parted.
“How do you mean?” I asked.
“Oh, they’re replacing them with catamarans. Catamarans are faster, but they’re not so elegant, and they’re not fun to pilot. But that’s progress, I guess.”
Everywhere in Sydney these days, change and progress are the watchwords (口号), and traditions are increasingly rare. Shirley Fitzgerald, the city’s official historian, told me that in its rush to modernity in the 1970s, Sydney swept aside much of its past, including many of its finest buildings. “Sydney is confused about itself,” she said. “We can’t seem to make up our minds whether we want a modern city or a traditional one. It’s a conflict that we aren’t getting any better at resolving (解决).”
On the other hand, being young and old at the same time has its attractions. I considered this when I met a thoughtful young businessman named Anthony. “Many people say that we lack culture in this country,” he told me. “What people forget is that the Italians, when they came to Australia, brought 2000 years of their culture, the Greeks some 3000 years, and the Chinese more still. We’ve got a foundation built on ancient cultures but with a drive and dynamism of a young country. It’s a pretty hard combination to beat.”
He is right, but I can’t help wishing they would keep those old ferries.

3 . Goffin’s cockatoos, a kind of small parrot native to Australasia, have been shown to have similar shape-recognition abilities to a human two-year-old. Though not known to use tools in the wild, the birds have proved skilful at tool use while kept in the cage. In a recent experiment, cockatoos were presented with a box with a nut inside it. The clear front of the box had a “keyhole” in a geometric shape, and the birds were given five differently shaped “keys” to choose from. Inserting the correct “key” would let out the nut.
In humans, babies can put a round shape in a round hole from around one year of age, but it will be another year before they are able to do the same with less symmetrical (对称的) shapes. This ability to recognize that a shape will need to be turned in a specific direction before it will fit is called an “allocentric frame of reference”. In the experiment, Goffin’s cockatoos were able to select the right tool for the job, in most cases, by visual recognition alone. Where trial-and-error was used, the cockatoos did better than monkeys in similar tests. This indicates that Goffin’s cockatoos do indeed possess an allocentric frame of reference when moving objects in space, similar to two-year-old babies.
The next step, according to the researchers, is to try and work out whether the cockatoos rely entirely on visual clues (线索), or also use a sense of touch in making their shape selections.
1. How did the cockatoos get the nut from the box in the experiment?A.By following instructions. | B.By using a tool. |
C.By turning the box around. | D.By removing the lid. |

4 . Popularization has in some cases changed the original meaning of emotional (情感的) intelligence. Many people now misunderstand emotional intelligence as almost everything desirable in a person's makeup that cannot be measured by an IQ test, such as character, motivation, confidence, mental stability, optimism and “people skills.” Research has shown that emotional skills may contribute to some of these qualities, but most of them move far beyond skill-based emotional intelligence.
We prefer to describe emotional intelligence as a specific set of skills that can be used for either good or bad purposes. The ability to accurately understand how others are feeling may be used by a doctor to find how best to help her patients, while a cheater might use it to control potential victims. Being emotionally intelligent does not necessarily make one a moral person.
Although popular beliefs regarding emotional intelligence run far ahead of what research can reasonably support, the overall effects of the publicity have been more beneficial than harmful. The most positive aspect of this popularization is a new and much needed emphasis (重视) on emotion by employers, educators and others interested in promoting social well-being. The popularization of emotional intelligence has helped both the public and researchers re-evaluate the functionality of emotions and how they serve people adaptively in everyday life.
Although the continuing popular appeal of emotional intelligence is desirable, we hope that such attention will excite a greater interest in the scientific and scholarly study of emotion. It is our hope that in coming decades, advances in science will offer new perspectives (视角) from which to study how people manage their lives. Emotional intelligence, with its focus on both head and heart, may serve to point us in the right direction.
1. What is a common misunderstanding of emotional intelligence?A.It can be measured by an IQ test. | B.It helps to exercise a person’s mind. |

5 . Given the astonishing potential of AI to transform our lives, we all need to take action to deal with our AI-powered future, and this is where AI by Design: A Plan for Living with Artificial Intelligence comes in. This absorbing new book by Catriona Campbell is a practical roadmap addressing the challenges posed by the forthcoming AI revolution (变革).
In the wrong hands, such a book could prove as complicated to process as the computer code (代码) that powers AI but, thankfully, Campbell has more than two decades’ professional experience translating the heady into the understandable. She writes from the practical angle of a business person rather than as an academic, making for a guide which is highly accessible and informative and which, by the close, will make you feel almost as smart as AI.
As we soon come to learn from AI by Design, AI is already super-smart and will become more capable, moving from the current generation of “narrow-AI” to Artificial General Intelligence. From there, Campbell says, will come Artificial Dominant Intelligence. This is why Campbell has set out to raise awareness of AI and its future now — several decades before these developments are expected to take place. She says it is essential that we keep control of artificial intelligence, or risk being sidelined and perhaps even worse.
Campbell’s point is to wake up those responsible for AI—the technology companies and world leaders—so they are on the same page as all the experts currently developing it. She explains we are at a “tipping point” in history and must act now to prevent an extinction-level event for humanity. We need to consider how we want our future with AI to pan out. Such structured thinking, followed by global regulation, will enable us to achieve greatness rather than our downfall.
AI will affect us all, and if you only read one book on the subject, this is it.

6 . We all know fresh is best when it comes to food. However, most produce at the store went through weeks of travel and covered hundreds of miles before reaching the table. While farmer’s markets are a solid choice to reduce the journey, Babylon Micro-Farm (BMF) shortens it even more.
BMF is an indoor garden system. It can be set up for a family. Additionally, it could serve a larger audience such as a hospital, restaurant or school. The innovative design requires little effort to achieve a reliable weekly supply of fresh greens.
Specifically, it’s a farm that relies on new technology. By connecting through the Cloud, BMF is remotely monitored. Also, there is a convenient app that provides growing data in real time. Because the system is automated, it significantly reduces the amount of water needed to grow plants. Rather than watering rows of soil, the system provides just the right amount to each plant. After harvest, users simply replace the plants with a new pre-seeded pod (容器) to get the next growth cycle started.
Moreover, having a system in the same building where it’s eaten means zero emissions (排放) from transporting plants from soil to salad. In addition, there’s no need for pesticides and other chemicals that pollute traditional farms and the surrounding environment.
BMF employees live out sustainability in their everyday lives. About half of them walk or bike to work. Inside the office, they encourage recycling and waste reduction by limiting garbage cans and avoiding single-use plastic. “We are passionate about reducing waste, carbon and chemicals in our environment,” said a BMF employee.
1. What can be learned about BMF from paragraph 1?A.It guarantees the variety of food. | B.It requires day-to-day care. |
C.It cuts the farm-to-table distance. | D.It relies on farmer’s markets. |

9 . Do you ever get to the train station and realize you forgot to bring something to read? Yes, we all have our phones, but many of us still like to go old school and read something printed.
Well, there’s a kiosk (小亭) for that. In the San Francisco Bay Area, at least.
“You enter the fare gates (检票口) and you’ll see a kiosk that is lit up and it tells you can get a one-minute, a three-minute, or a five-minute story,” says Alicia Trost, the chief communications officer for the San Francisco Bay Area Rapid Transit — known as BART. “You choose which length you want and it gives you a receipt-like short story.”
It’s that simple. Riders have printed nearly 20,000 short stories and poems since the program was launched last March. Some are classic short stories, and some are new original works.
Trost also wants to introduce local writers to local riders. “We wanted to do something where we do a call to artists in the Bay Area to submit stories for a contest,” Trost says. “And as of right now, we’ve received about 120 submissions. The winning stories would go into our kiosk and then you would be a published artist.”
Ridership on transit (交通) systems across the country has been down the past half century, so could short stories save transit?
Trost thinks so.
“At the end of the day all transit agencies right now are doing everything they can to improve the rider experience. So I absolutely think we will get more riders just because of short stories,” she says.
And you’ll never be without something to read.
