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．"
1.The passage details Howard's life as a POW to show that ．
A.war cannot stop his pursuit of success.
B.passion for art helped ease his sufferings.
C.loss of freedom encouraged his creativity.
D.misery drives him to fight against his fate.
2.What can we infer about Howard's comic strip in prison？
A.It satisfied prisoners' curiosity．
B.It aroused the guards' sympathy．
C.It was popular among the prisoners．
D.It raised prisoners' confidence in freedom．
3.What contributes to the stranger's success in finding Morgan？
A.The email from a gentleman．
B.Howard's experience in the war．
C.Morgan's recalling of his father．
D.Morgan's status in the field of art．
4.What can we infer about Morgan from the last paragraph？
A.He didn't believe the stranger's story．
B.He was excited to get the comic strip．
C.He couldn't wait to tell others his good news．
D.He hadn't heard about his father's war stories．
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．
1.In which bookshop can you buy a drink while visiting？
A.Daikanyama T﹣site.
B.City Lights.
C.Shakespeare and Company.

The first foreign language I never learnt was French, but it didn’t go very well. My mother asked our neighbor teach me when I was seven. French wasn’t his native languages, but he used to live in France, so he could speak a little. However, I learnt very little until I didn’t feel it related to my daily life anyway. When I entered into senior high school, my attitude to language learning changed. I decided to learn Latin, that I’ve always been interested in because I want to study law. Learning Latin wasn’t a struggle for myself for this reason. Soon I begin to read classic books in Latin. Read those books opened a window for me to another world or gave me a new point of view on my own world.

If you’ve ever ridden public transport, you’ve probably heard snoring(打鼾) and found someone sleeping in the seat across from you. The natural vibration(震动) of buses and subways 1.(make) us feel sleepy, according to a new study in Science Alert.
Why? It’s all about sensory input-information going to your brain. On a bus, your senses give you 2.(continue) and repeating information. For example, the air conditioner and engine create constant white noise. Meanwhile, you are sitting still and your 3.(surrounding) don’t change. The vibrations of the engine are also opening. Your brain has almost no new information to process.
Repeating information will be 4.(ignore) eventually and your brain will enter a low-energy state. The fact that you fall asleep quickly with your eyes 5.(close) on a bus is because your brain gets used to all the repeat.
“When you’re tired, it doesn’t take much time 6.(start) nodding off and we’ve found that the gentle vibrations made by car seats 7. you drive can loose(使放松) your brain and body,” said Stephen Robinson, 8. researcher from the RMIT University in Melbourne, Australia.
Robinson’ s team mentioned 15 volunteers’ heart rate variability(心率变异性)—a well-known indicator of sleepiness. This line of research can assist in the development of practical and relevant guidelines for limiting 9.(expose) to vibrations in the car industry. Robinson believed that the research could be helpful 10. improving road safety. “We hope that future car seat designs can build in features to disturb this lulling effect and fight vibration-induced(震动引起的) sleepiness,” he said.
