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.
1.What helps predict the speed of one's brain ageing?
A.One's health condition.
B.A test result at the age of 3.
C.The actual age of one's brain.
D.A machine for medical check.
2.What is the purpose of Elliott's research?
A.To find out why people look older or younger.
B.To measure people's brain age at different stages.
C.To discover whether brain age can be measured by machines.
D.To explore the relationship between brain age and future health.
3.What is Paragraph 4 mainly about?
A.The influence of cognitive tests.
B.The procedure of Elliott's study.
C.The information about volunteers.
D.The findings of the brain research.
4.What do the findings of the research imply?
A.We should test our brain age earliest possible.
B.People suffering dementia can go on working.
C.Brain ageing could be predicted at an early age.

A peer is a person who is about the same age as you. Peers affect your life, whether you know it or not, just by spending time with you.
1. Maybe another student in your science class taught you an easy way to remember the planets in solar system. Maybe you got others excited about your new favorite book and now everyone’s reading it. However, sometimes peers affect one another in another way.2. Maybe a kid in the neighborhood wanted you to steal with him.
Some kids give in to peer pressure because they want to be liked, to fit in, or because they worry that other kids may make fun of them if they don’t go along with the group.3. The idea that “everyone’s doing it” may influence some kids to leave their better judgments or their common senses behind.
Peer pressure can be extremely strong and hard to get rid of. Experiments have shown how peer pressure can influence someone to change her/his mind from what she/he knows for sure is a correct answer to the incorrect answer-just because everyone else gives the incorrect answer!4.
5. Paying attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do. Inner strength and self-confidence can help you stand firm, walk away and resist doing something when you know better.
A. Peers can have a good effect on one another.
B. Peer pressure is the direct influence on people by peers.
C. Good peers may give you a hand when you are in trouble.
D. That holds true for people of any age in peer pressure situations.
E. Maybe one kid in school tried to get another to cut class with him.
F. It can be hard to walk away from peer pressure, but it can be done.
G. Others may go along because they are curious to try something new that others are doing.

Easy Ways to Keep Your Brain Sharp
Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing.1 Read on for some techniques worth trying.
1. 2
People who regularly made plans and looked forward to upcoming events had a 50 percent
reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study.3
Something as simple as setting a goal to have a weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.
2. Go for a walk.
Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact,exercise produces chemicals that are good for your brain.4
3. Learn something new.
Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time.5 Or go dancing with your friends.
A.Focus on the future.
B.This can be especially harmful to the aged.
C.It should be something like learning gardening.
D.So take a few minutes each day to do some reading.
E.But don't worry if your schedule isn't filled with life-changing events.
F.Luckily, research shows there is a lot you can do to avoid those moments.
G.In other words, when you take care of your body, you take care of your brain.

[1]Do you remember the title of the last book you read? Are names sometimes just beyond your brain’s reach? While forgetfulness isn’t necessarily a sign that something’s wrong, it can be frustrating(令人沮丧的).But simple methods can help to sharpen your memory.
[2]Challenge your habits. Sometimes a little bit of habit changing goes a long way. For example,use the ‘wrong’ hand to do an everyday task several times a day.If you usually brush your teeth with your right hand, use your left.The brain ‘knows’ whew you're using the wrong hand.It’s that confusion that stimulates new brain circuits,as the brain struggles to master a new task.
[3]Get involved in niusic.Listening to music can improve your ability to concentrate and help you to remember what you’ve learnt.Some types of music actually cause brain neurons(神经细胞)to fire more quickly.If you’re really looking forward to sharpening your memory, take up a musical instrument.Whatever the instrument,learning to p1ay will tune your brain’s ability to analyse and focus.
[41Go out of your way to stay mentally active.What really counts is not the amount of book learning you did at school or university, it’s how much you actively use your mind.For example,doing crossword puzzles,learning a second language or playing games can exercise your brain.
[5] .Make sure that you get enough of the B vitamins in your diet.They help to repair brain tissue,and turn food into mental energy.Eat fish 2 or 3 times a week.If you drink coffee,you’ll not only get a short-term boost in your ability to concentrate but also long-term benefits as well.Besides, the brain is 85%water, so if you don’t drink at least 8 large glasses of water a day,you could suffer from memory loss.

高三英语单项填空中等难度题查看答案及解析
The music of your teenage years probably will stay with you for the rest of your life.I think music is deeply connected with memory because of the emotions it awakens.Music also helps to mark time because of the way the fashions and stars of pop culture come and go.I often connect some summers with particular records (唱片 ) that came out while I was on holiday.But what's really the best way to record your youth? Is it your favorite song, or a picture of the singer?
In my teenage years, one of the special things about Britain was the huge amount of information about music.There were 3 weekly newspapers about music:Sounds, Melody Maker and the New Musical Express.Buying records was expensive and it also meant making a choice.So it was wise to read about music instead, and in some ways, it was actually better as well.It was possible for a group to get onto the front cover of one of the music papers without even having made any records—but they needed things to say for the reporters to write about.In fact, the best pop stars of the 1980s were people whose main talent was exactly that.They weren' t great musicians or singers and they weren't especially goodlooking, but they had some unusual acts or habits and a nice way with clever phrases.They were ideal for filling music papers.
When The Face magazine first came out in May, 1980, it was meant to be a rock magazine.I have given away or sold all the records I bought as a teenager, but I think my old copies of The Face will stay with me for ever.Although it started out as a source of information about music, the writers quickly realized that it wasn't really the music that was important—it was the way people spoke and acted, and, above all, the way they looked.
1.According to the author,music can NOT ________.
A.improve memory B.awaken emotions
C.mark time D.stay in the mind
2.We can infer that during the author's teenage years,________.
A.there were few records for customers to buy
B.some songs he heard while on holiday impressed him
C.he spent most of his holiday time on music
D.he loved one pop song the most
3.According to Paragraph 2,during the author's teenage years,________.
A.people had few chances to buy records
B.it was hard to judge whether records were good or not
C.it was not an easy thing for teenagers to get records
D.the choice of buying records only depended on newspapers
4.The underlined word “that” in Paragraph 2 means that ________.
A.people could get onto the music papers without having made any records
B.people's talent was not what reporters needed to write about
C.reporters wrote about the talents of pop stars
D.people read about music

A strong memory depends on the health and vitality of your brain.They say that you can’t teach an old new tricks, but when it comes to the brain, scientists have discovered that this old saying simply isn’t true.1. .
Give your brain a workout.Memory, like muscular strength, requires you to “use it or lose it”.The more you work out your brain, the better you’ll be able to process and remember information.2. .
Don’t skip the physical exercise.While mental exercise is important for brain health, that doesn’t mean you never need to break a sweat.Physical exercise helps your brain stay sharp.It increases oxygen to your brain and reduces the risk for disorders that lead to memory loss.
Get enough sleep.There is a big difference between the amount of sleep you can get by on and the amount you need to function at your best.3. .
Keep stress in check.Stress is one of the brain’s worst enemies.Over time, stress destroys brain cells.Studies have also linked stress to memory loss.
Have a laugh.4. That holds true for the brain and the memory, as well as the body.Unlike emotional responses, which are limited to specific areas of the brain, laughter engages multiple regions across the whole brain.
__5.__ Just as the body needs fuel, so does the brain.You probably already know that a diet based on fruits, vegetables, whole grains, “healthy” fats and lean protein will provide lots of health benefits, but such a diet can also improve memory.For brain health, though, it’s not just what you eat—it’s also what you don’t eat.
A.Eat a brain-boosting diet.
B.Play games with memory.
C.Laughter is the best medicine.
D.But oversleeping is not good for your brain.
E.Even skipping a few hours makes a difference!
F.You have to shake things up from time to time!
G.The human brain has an astonishing ability to adapt and change.
