Your brain isn't necessarily the same age as the rest of you． Now， it may be possible to predict how quickly a person's brain will age throughout life based on tests taken when he or she is three years old．
A person's biological age may be a better indicator of their health than their real age． Brain age can be measured using brain scans and machine﹣learning to determine if a person's brain looks older or younger than the average healthy brain for people of the same age．
To find out if brain age might reveal anything about a person's health in midlife， Max Elliott at Duke University in North Carolina and his colleagues assessed the brains of 869 adults in New Zealand who have undergone regular medical and cognitive （认知的） testing since they were 3 years old．
When the volunteers， all aged between 43 and 46， underwent MRI brain scans， the team found that their brain ages ranged from 23 to 71． Those with older brain ages performed worse on tests of cognition， memory and IQ． The researchers also found that some people have a very advanced brain age but their bodies seem to be ageing slowly， and vice versa （反之亦然）． However， the team found that those who had the highest scores on cognitive tests when they were 3 years old went on to have the youngest﹣looking brains．
This suggests we might be able to tell who is at risk of accelerated brain ageing early in life． Researchers hope that predicting brain ageing earlier in life could allow treatments for conditions like dementia （痴呆） to be started sooner． This means treatments might have a better chance of working．
We don't yet have a way to treat brain ageing， but given the known benefits to the brain of healthy eating and exercise， these aren't a bad place to start．

Howard Weistling wanted to be a comic strip （连环漫画） artist． But when the Japanese bombed Pearl Harbor， he joined the Army．
After flight engineer training， Howard was shipped off to Europe． On his maiden flight， his plane was shot down over Austria． The entire crew of eight men landed safely． But a farmer found Howard hiding in his barn and turned him over to a prison of war camp in Barth， Germany． It was freezing and the men almost starved to death eating the guards' garbage．
Hungry and homesick Howard coped the only way he knew how． He drew a comic strip． The book， made of cigarette wrappers bound together with scrap metal， was sent around the camp． Every couple of days he would add a new panel． One panel at a time would be passed around the whole camp． And they'd have something to look forward to．
After an entire year of this， they woke one morning to find their guards gone． They fled and Howard finally got to go home． Just lucky to get out alive， he left the book behind．
Back home in California， Howard soon had a wife and kids to feed so he had to set aside his dream of becoming an artist． He took a job as a gardener instead．
Morgan shared his father's artistic gifts． At 15 his parents sent him to art school． And Howard got to see his son become a well﹣known painter before he died in 2002． That's how， seven decades after the war， when a stranger in New York googled the name "Weistling，" he found Morgan online．
"I get an email from a gentleman and he says， ‘I think I may have some drawings your father did when he was a POW （prisoner of war） in World War II，'" Morgan recalls． "‘Would you like them？' And I just stared at that email and started crying．"
Luckily Howard had engraved his name on the comic book， which is how the man from New York City had connected with Morgan． A couple of days later when it arrived in California， Morgan couldn't believe it． "It was like getting my father back，" Morgan says． "It was like him being able to tell me the story over again ﹣ only this time it was real in my hands．"

The Worlds' Best Bookshops
There's nothing like being surrounded by books， wherever you are． Here are the finest oases of literature that travellers can bring you．
Daikanyama T﹣site | Tokyo
It is well worth visiting even if just to admire the building's beautiful， crisscrossed architecture． Once you've had your fill of roaming three floors' worth of bookshelves， there's the bar， the coffee shop， or even the video rental space to give you more reason to stay just that little bit longer． Grab a book， order a beer and dive into its pages． I could have stayed hours here．
City Lights | San Francisco
The three﹣storey establishment publishes and sells titles in poetry， fiction， translation， politics， history and the arts． It hosts events and readings， and runs a non﹣profit of the same name that aims to promote diversity of voices and ideas in literature． It's opposite Vesuvio， a bar frequented by Kerouac and other Beat﹣generation writers and artists．
Shakespeare and Company | Paris
I made a special trip to the Left Bank for this one when I was in Paris． It has two floors packed with English﹣language texts， and I was particularly struck by any spare wall space devoted to notes from visitors ﹣ heartfelt messages to a loved one， dedications to the shop itself， or a quote from a favourite author or philosopher．
Hutatma Chowk | Mumbai
A few years ago I visited India， investigating Rudyard Kipling's connections with the country． I spotted a cheap copy of The Jungle Book on one of the tarp﹣covered book stalls at Hutatma Chowk （Martyrs' Square）． The booksellers here are like amateur librarians， able to lay their hands on almost any title you ask for． To me， those well﹣thumbed （翻旧了的） books spoke volumes about the changes of Mumbai's readers in the 150 years since the city gave us Kipling．

Described as the world’s most environmentally friendly protein（蛋白质）, Solein is made by applying electricity to water to release bubbles of carbon dioxide and hydrogen. Living microbes (微生物) are then added to the liquid to feed on the carbon dioxide and hydrogen bubbles and produce the Solein, which is then dried to make the powder. It’s a chemical change process similar to beer brewing. The dried Solein has a protein content of 50 percent and looks and tastes just like wheat flour.
“It is a completely new kind of food, a new kind of protein, different to all the food on the market today in how it is produced as it does not need agriculture.” Dr Pasi Vainikka, the chief manager of Solar Foods told The Guardian. The process used to produce Solein—changing hydrogen and carbon dioxide is amazing, as the wonder food can be produced anywhere in the world. It’s also 10 time-efficient than photosynthesis (光合作用), and 10 to 100 times more environment and climate-friendly in water use than animal or plant-based food production.
“Solein also contains all the essential amino acid (氨基酸),but because it is produced using carbon and electricity, it does not require large amounts of land to produce, ” the Solar Foods website explains. “Another unique characteristic of Solein is that it is able to take carbon directly from carbon dioxide without needing a source of sugar.”
While Solar Foods does not expect Solein to challenge conventional protein production methods in the next two decades, it does expect it to become a “new harvest” for humanity, which is significant considering so far we have only relied on plants and animals for sustenance. The Helsinki-based company plans to open its first Solein factory at the end of 2021 and increase production to two billion meals per year by 2022.
1.Why is Solein described as environmentally friendly?
A.Because it is man-made by using electricity.
B.Because it contains all the nutrition people need.
C.Because it is made consuming less land and energy.
D.Because it is produced from water and carbon dioxide.
2.What does Solar Foods expect of Solein?
A.It’ll have a rewarding future.
B.It’ll reach consumers in 2020.
C.It’ll challenge traditional protein production.
D.It’ll be a complete replacement for plants and animals.
3.What does the underlined word “sustenance” in last paragraph mean?
A.survival B.food
C.material D.support
4.Where is this text most likely from?
A.A textbook. B.A novel.
C.A magazine. D.A brochure.
Every year, thousands of teenagers participate in programs at their local art museums. But do any of them remember their time at museum events later in life? A new report suggests that the answer is yes – and finds that alumni (毕业生) of arts-based museum programs credit them with changing the course of their lives, even years after the experience.
The Whitney Museum of American Art, the Walker Art Center and the Museum of Contemporary Art, Los Angeles recently asked researchers to conduct a study to find out how effective their long-standing teen art programs really are. They involved over 300 former participants of four programs for teens that have been in existence since the 1990s. Alumni, whose current ages range from 18 to 36, were invited to find out how they viewed their participation years after the fact.
Among the alumni surveyed, 75 percent of alumni rated the teen program experience as the most favorable influence on their own lives, beating family, school and their neighborhoods. Nearly 55 percent thought that it was one of the most important experiences they’d ever had, regardless of age. And two-thirds said that they were often in situations where their experience in museums affected their actions or thoughts.
It turns out that participating in art programs also helps keep teens enthusiastic about arts even after they reach adulthood: 96 percent of participants had visited an art museum within the last two years, and 68 percent had visited an art museum five or more times within the last two years. Thirty-two percent of program alumni work in the arts as adults.
Though the study is the first of its kind to explore the influence of teen-specific art programs in museums, it reflects other research on the important benefits of engaging with the arts. A decade of surveys by the National Endowment for the Arts found that childhood experience with the arts is significantly associated with their income and educational attainment as adults. Other studies have linked arts education to everything from lower drop-out rates to improvement in critical (批判性的)thinking skills.
1.What does the underlined phrase “the experience” in Paragraph 1 refer to?

How do you kill your time when you go to work? Most of us stare at our cell phones, and refuse to make eye contact with others. We just read, chat with others online or play games online. Or maybe we’re using the time between stops to do our makeup, catch up on emails, or read a few chapters of a book. However, Dina Alfasi takes a very different approach.
Each day she has to travel hours on buses and trains to get to her engineering job at a hospital in Israel. Rather than look at her cell phone in silence, she uses one very special way to have connection with strangers. It is portraits of the people she meets on public transport every day that she is taking. The photographs catch those quiet and personal moments of people readying themselves for the day ahead. Some people lean (倚靠) their head against the window and go to sleep, some stare into space and have a daydream, and others sit quietly to read their documents or books. Each picture catches one tiny moment in people’s lives, ripe with potential for your imagination. It is wonderful for her to look at someone’s commute (上下班) and make up an entire story about the rest of their daily existence, from the father travelling with a baby to the woman welcoming a change.
“What inspires me very much are the little moments that happen every day,” Dina told My Modern Met. “My work is to tell stories through a single portrait, and it proves that all you need is just to look around and find those magic moments.”
1.What will most people do when going to work?
A.Enjoy reading a book loudly.
B.Make eye contact with others.
C.Have face-to-face talks with others.
D.Concentrate on their mobile phones.
2.What makes Dina different from others?
A.Staring into the space and having a daydream.
B.Leaning against the window and relaxing herself.
C.Using her mobile phone to appreciate pictures she draws.
D.Drawing people while travelling on buses and trains to work.
3.Which word can best describe Dina Alfasi?
