Walking to Exercise the Brain
Do you think sitting and studying all the time will improve your grades?Think again.Getting some exer-
cise may help,too.
New research with old people suggests that taking regular walks helps them pay attention better than if
they didn't exercise.
Previous research had shown that mice learn,remember,and pay attention better after a few weeks of
working out on a running wheel.Mice that exercise have greater blood flow to the brain than those who don't.
Their brain cells also make more connections.
Neuroscientists（神经科学家）from the University of Illinois at Urbana Champaign wanted to find out if
the same thing is true for people.First,they measured the physical fitness of 41 adults,ages 58 to 77,after
each person walked 1 mile.Then,participants looked at arrows on a computer screen and had to use computer
keys to show which way one particular arrow was pointing.
Adults who were physically fit were faster at the arrow task,and their answers were just as accurate as
their less-fit peers,the researchers found.The fitter participants also had more blood flow to a part of their
brain responsible for paying attention and making decisions.
In a second study , 15 elderly people who completed a 6-month aerobic-training（有氧运动）course were
faster at attention tasks compared with 14 seniors who just did stretching and toning exercises（韵律操）for
the same amount of time.
So,even going for a walk every 2 or 3 days for just 10 to 45 minutes can help.That should be good news
for the elderly.
The effects of exercising on the brains of younger people haven't been studied yet. Still,it can't hurt to
take occasional breaks and go for a walk or run around with friends.Whatever you do,though,don't try to
read and walk at the same time.You could end up hurting yourself!

共用题干Research shows we make up our minds about people through unspoken communication within seven seconds of meeting them. Consciously or unconsciously,we show our true feelings with our eyes,faces,bodies and attitudes,causing a chain of reactions,ranging from comfort to fear.Think about some of your most unforgettable meetings:an introduction to your future spouse,a job interview,an encounter with a stranger. Focus on the first seven seconds.What did you feel and think?How did you"read"the other person?How do you think he read you?You are the message.For 25 years I've worked with thousands who want to be successful.I've helped them make persuasive presentations,answer unfriendly questions,communicate more effectively.The secret has always been you are the message.Others will want to be with you and help you if you use your good qualities.They include:physical appearance,energy,rate of speech, pitch and tone of voice,gestures,expression through the eyes,and the ability to hold the interest of others.Others form an impressiont about you based on these. Think of times when you know you made a good impression.What made you successful?You were committed to what you were talking about and so absorbed in the moment you lost all self-con-sciousness.Many books advise you to stride into a room and impress others with your qualities.They instruct you to greet them with"power handshakes"and tell you to fix your eyes on the other person. If you follow all this advice,you'll drive everyone crazy一including yourself.The trick is to be consistent at your best.The most effective people never change from one situation to another. They're the same whether they're having a conversation,addressing their garden club or being interviewed for a job.They communicate with their whole being;the tones of their voices and their gestures match their words.Physical appearance is the most important quality which may help us to communicate with others。A:Right B:Wrong C:Not mentioned

For example,rather than trying to recall a random list of groceries,we can divide them into categories,such as dairy,meat and produce. For important things like keys and money,we can set up a"forget-me-not"spot where we always keep them.We can also eat to aid our memory power. Whole grains,fruits and vegetables are excellent sources of glucose,the brain's preferred fuel. Another low-tech way to improve memory is to get adequate rest. Sleep may allow our brain time to encode memories.Interest in friends,family and hobbies does wonders for our memory.A sense of passion or purpose helps us remember. Memory requires us to pay attention to our lives,allowing us to discover in them everything worth remembering.Some people tend to have better memories than the rest of us.A:Right B:Wrong C:Not mentioned

共用题干第二篇Three Ways to Become More CreativeMost people believe they don't have much imagination.They are wrong. Everyone has imagination,but most of us,once we become adults,forget how to access it. Creativity isn't always connected with great works of art or ideas.People at work and in their free time routinely think of creative ways to solve problems.Maybe you have a goal to achieve,a tricky question to answer or you just want to expand your mind!Here are three techniques to help you.This technique involves taking unrelated ideas and trying to find links between them.First,think about the problem you have to solve or the job you need to do.Then find an image,word,idea or object,for exam- pie,a candle.Write down all the ideas/words associated with candles:light,fire,matches,wax,night,silence, etc.Think of as many as you can?The next stage is to relate the ideas to the job you have to do?So imagine you want to buy a friend an original present,you could buy him tickets to a match or take him out for thenight.Imagine that normal limitations don't exist. You have as much time/space/money,etc.as you want. Think about your goal and the new possibilities.If,for example,your goal is to learn to ski,you can now prac- tice skiing every day of your life(because you have the time and the money).Now adapt this to reality.May- be you can practice skiing every day in December,or every Monday in January.Look at the situation from a different point of view. Good negotiators（谈判者）use this technique in business; and so do writers.Fiction writers often imagine they are the characters in their books.They ask questions: what does this character want?Why can't she get it?What changes must she make to get what she wants? What does she dream about?If your goal involves other people,put yourself" in their shoes".The best fisher- men think like fish!The second technique suggests that you just imagine _______________.A:setting a goal is as simple as skiingB:you have every resource to achieve your goalC:new possibilities will soon appearD:December and January are the best months for skiing
共用题干Personality and Career1.When you select your career,there's a whole lot more to it than assessing your skills and matching them with a particular position.If you ignore your personality,it will hurt you long-term regardless of your skills or the job's pay.There are several areas of your personality that you need to consider to help you find a good job.2. There are isolating（使孤立）jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy.Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.3.Most jobs these days have some elements of change to them,but some are more than others. If you need stability in your life,you may need a job where the changes don't happen so often.Other people would be bored of the same daily routine.4.There are people who are happy to spend more than 40 hours a week on a computer,while there are others who need a lot of human interaction throughout the day.Again,these are extremes and you'll likely find a lot of positions somewhere in the middle as well.5.Some people prefer a smaller setting where you'll get to know almost all the people there fairly quickly to being in a large building with a lot of people you won't know immediately.6.Anyway,these are a great starting point for you.I've seen it over and over again with people that they make more money over time when they do something they love.It may take you a little longer,but making a move to do what you have a passion for can change the course of your life for the better.If you are easily bored of daily routine,you'd better_________. A:find a job with many elements of changeB:try different areas and fieldsC:consider your skills and personalityD:prefer a smaller settingE:feel uneasy with a job involving too much time on computers F: make you uncomfortable

共用题干第三篇Walking to Exercise the BrainDo you think sitting and studying all the time will improve your grades?Think again?Getting some exer-cise may help,too.New research with old people suggests that taking regular walks helps them pay attention better than ifthey didn't exercise.Previous research had shown that mice learn,remember,and pay attention better after a few weeks ofworking out on a running wheel.Mice that exercise have greater bl0od flow to the brain than those who don't.Their brain cells also make more connections.Neuroscientists（神经科学家）from the University of Illinois at Urbana-Champaign wanted to find out ifthe same thing is true for people.First,they measured the physical fitness of 41 adults,ages 58 to 77,after each person walked 1 mile.Then,participants looked at arrows on a computer screen and had to use computerkeys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task,and their answers were just as accurate astheir less-it peers,the researchers found.The fitter participants also had more blood flow to a part of theirbrain responsible for paying attention and making decisions.In a second study , 15 elderly people who completed a 6-month aerobic-training（有氧运动）course werefaster at attention tasks compared with 14 seniors who just did stretching and toning exercises（韵律操）for the same amount of time.So,even going for a walk every 2 or 3 days for just 10 to 45 minutes can help.That should be good news for the elderly.The effects of exercising on the brains of younger people haven't been studied yet.Still,it can't hurt to take occasional breaks and' go for a walk or run around with friends.Whatever you do,though,don't try to read and walk at the same time.You could end up hurting yourself!Walking regularly helps elderly people___________.A:lose weightB:become happierC:concentrate betterD:look younger

问答题◆Topic 3: Will petty criminals get light punishment? Questions for Reference: 1. A new prosecution guideline was recently released: people convicted of petty crimes may get light punishment if they are minors, the elderly people, and people who have slightly breached the law because of poverty. What do you think of this new law? 2. This new law is said to be a humane practice and it will help them put their lives back in order and better serve their families. Do you think it can achieve its end? 3. Some people think that if petty crimes are not punished in a timely way, more serious consequences will follow. What do you think of this argument?
