There’s more evidence that what’s good for your heart is good for your head．A new study shows that people who run，swim or do other moderate intensity(中等强度的)exercise have brains that look，on average，10 years younger than the brains of couch potatoes．

“Our study showed that for older people，getting moderate intensity exercise may be protective，helping them keep their brains work better，”said Dr．Clinton Wright of the University．Of Miami，who led the study．But it’s not necessarily easy．Walking，golf，bowling and yoga didn’t count，and people need to start before they begin showing memory loss，Wright’s team reported in the journal Neurology．

The study of nearly 900 people who exercise regularly showed that 90 percent fell into the low-intensity group．These people are part of a larger group taking part in a bigger study called Northern Manhattan Study．They were asked how long and how often they exercised during the past two weeks．Five years later，they were tested for memory and thinking skills and got a brain MRI．Seven years after that，they took the memory and thinking tests again．The 10 percent who said they took part in moderate intensity exercise scored better on the tests．These included running，climbing，swimming，riding bicycles and so on．

“We found that those with moderate heavy activity had higher scores and slower decline than inactive patients when comparing the results，”the study team wrote．

Many studies have shown that exercise may not prevent Alzheimer’s but may delay it．The findings fit in with a study that found two years of exercising，eating healthier food and brain training can promote people’s memory function．

1.According to the study，moderate heavy exercise________.

A．makes people’s heart better than their heads

B．helps people keep a younger brain

C．makes people ten years younger

D．makes people look like potatoes

2.What’s true about the study?

A．Most people surveyed took low-intensity exercise．

B．Only 900 people took part in the bigger study．

C．High-intensity exercise is better．

D．Ten people scored best on the test．

3.How did the study team come to the conclusion?

A．By observing people exercise．

B．By using examples．

C．By making a comparison．

D．By doing a brain MRI．

4.What’s the best title for this passage?

A．How to keep healthy

B．Ways to make your brain work better

C．To exercise or not

D．Moderate exercise keeps your brain younger

Getting old might not be something that's yet to cross your mind. But ageing is unavoidably going to get the better of us one day. And that’s why scientists are constantly seeking out evidence that will show us what we need to do to achieve longevity.

We all know that regular exercise is good for us. In recent years, although we've been told to aim to walk 10,000 steps a day to remain healthy, other advice to do three quick and energetic 10-minute walks a day is thought to be even more effective. And the latest piece of research might put a spring in your step if you’re someone who walks at a fast pace. That’s because, according to scientists, the speed at which people walk in their 40s is a sign of how much their brains, as well as their bodies, are ageing.

Tests on 1,000 people from New Zealand born in the 1970s found that slower walkers tended to show signs of "accelerated ageing". Their lungs, teeth and immune systems were in worse shape than those who walked fester. And what’s worse, the study found not only did slower walkers' bodies age more quickly, their faces looked older and they had smaller brains.

This might be seen as a wake-up call for people with a slower pace who might feel it's time to work out get fitter. But it might be too late; researchers say they were able to predict the walking speed of 45-year-olds using the results of intelligence, language and motor skills tests from when they were aged three. They also suggest that even in early life, there are signs showing which people will go on to have a healthier life.

So, what's the point of knowing that a slower walking pace might mean a smaller brain? Well, researchers say measuring walking speed at a younger age, and understanding what this might mean, could be a way of testing treatments to slow human ageing. This might help us make lifestyle changes while we're still young and healthy. Any steps we can take to prolong a good mental and physical state is a no brainer!

1.Which of the following is considered to be a better choice?

A.Walking 10,000 steps a day. B.Doing three quick and energetic walks a day.

C.Doing irregular exercise every day. D.Frequently doing sports in spring.

2.What can be inferred from the passage?

A.Faster walkers will get fitter, be younger and have bigger brains.

B.People's health condition can be predicted from their walking speed at 45.

C.This study found that slower walkers age more slowly.

D.People who walk faster are more brilliant than slower walkers.

3.What does the underlined word "prolong" in Para.5 mean?

A.give something up B.transfer something at random

C.make something last longer D.put something off

4.What would be the best title?

A.Walking to Stay Young B.Getting Old and Doing Exercise

C.Having a Happy Life D.Slow Walking and Ageing

Getting old might not be something that's yet to cross your mind. But aging is going to defeat us one day, so it's something we'd all like to control.

It would be great to have a long, healthy and happy life, and that's why scientists are constantly seeking out what we need to do to achieve it. We all know that regular exercise is good for us. But the latest piece of research might put a spring in your step if you're someone who walks at a fast pace. That's because the speed at which people walk in their 40s is a sign of how much their brains and their bodies are aging.

The BBC's Philippa Roxby writes that tests on 1,000 people found that slower walkers tended to show signs of "accelerated aging”. Their lungs, teeth and immune systems were in worse shape than those walking faster. The study also found not only did slower walkers bodies age more quickly, their faces looked older and they had smaller brains.

This might be seen as a wake-up call for people with a slower pace to work out and get fitter. But it might be too late； researchers say they were able to predict the walking speed of 45-year-olds using the results of intelligence, language and motor (运动)skills tests from when they were aged three. They also suggest that even in early life, there are signs showing which people will have a healthier life.

So, what's the point of knowing that a slower walking pace might mean a smaller brain? Researchers say measuring walking speed at a younger age and understanding what this might mean could be a way of testing treatments to slow human aging.

1.Why do scientists keep on studying?

A.To help people live a better life. B.To achieve their goals.

C.To find ways to stop aging. D.To find out who can live longer.

2.How did the researchers get the result?

A.By analyzing data. B.By doing experiments int he lab.

C.By doing surveys. D.By carrying out tests on people.

3.The findings can be used to .

A.treat certain illnesses B.find ways to slow aging

C.make people work harder D.urge people to walk slowly

4.Where is the text most likely from?

A.A diary. B.A guidebook.

An important factor that plays a part in susceptibility （易受影响） to colds is age．A study done by the University of Michigan School of Public Health indicated the fact that seems to hold true for the general population．Babies are the group suffering most from colds, averaging more than six colds in their first years．Boys have more colds than girls up to age three．After the age of three, girls are more susceptible than boys, and teenage girls average three colds a year to boy's two．

The general frequency of colds continues to decline into adults．Elderly people who are in good health have as few as one or two colds annually．One exception is found among people in their twenties, especially women, who show a rise in cold infections（感染）, because people to this age group are most likely to have young children．Adults who delay having children until their thirties and forties experience the same sudden increase in cold infections．

The study also found that economics （经济状况） plays an important role．As income increases, the frequency at which colds are reported in the family decreases．Families with the lowest income suffer about a third more colds than families at the upper end．Lower income generally forces people to live in closer quarters than those typically occupied by wealthier people, and crowding increases the opportunities for the cold virus to travel from person to person．Low income may also influence diet．The degree to which poor nutrition affects susceptibility to colds is not yet clearly proved, but an inadequate diet is suspected of lowering resistance generally．

1.What factors cause people to catch colds easily?

A. Age and pregnancy．                  B. Health and pregnancy．

C. Health and economics．               D. Age and economics．

2.Why does the lowest income lead to the rapid spread of colds?

A. Because poor people can't afford to go to see a doctor．

B. Because balanced diet has definitely affected poor people．

C. Because people with the lowest income have limited living space．

D. Because cold virus don't have opportunities to travel in poor families．

3.How does the study prove that age plays a part in susceptibility to colds?

A. Using comparison．  B. Using graphs．

C. Using description．  D. Using argument．

4.What can you learn from the passage?

A. Families with the lowest income suffer less colds than rich families．

B. The general frequency of colds are likely to increase among the poor．

C. Women in their twenties are most likely to avoid cold infections．

D. The general frequency of colds continue to rise into the adults．

A recent experiment held in Japan shows that it is almost impossible for people to walk exactly straight for 60 metres. Tokyo University of Agriculture and Technology found 20 healthy men and asked them to walk as straight as possible to a target 60 metres away at normal speed. Each man had to walk on white paper fixed flat to the floor wearing wet colored socks. The footprints revealed that all walked in a winding rather than a straight line. Researchers found that people readjust the direction of walking every few seconds. The amount of the winding differed from subject to subject. This suggests that none of us can walk in a strictly straight line. We walk in a winding way mainly because of a slight structural or functional imbalance of our limbs (四肢). Although we may start walking in a straight line, several steps afterwards we have changed direction.

Eyesight helps us to correct the direction of walking and leads us to the target. Your ears also help you walk. After turning around a lot with your eyes closed, you can hardly stand still, let alone walk straight.

It’s all because your ears help you balance. Inside your inner ear there is a structure which contains liquids. On the sides of the organ are many tiny hair-like structures that move around as the liquid flows. When you spin (旋转) the liquid inside also spins. The difference is that when you stop, the liquid continues to spin for a while. Dizziness is the result of these nerves in your ear. When you open your eyes, although your eyesight tells you to walk in a straight line, your brain will trust your ears more, thus you walk in a curved line.

1.The experiment held in Japan proved that _______.

A. the participants kept readjusting their direction of walking

B. all the participants had a good sense of direction

C. the experiment was done in different ways

D. none of the participants finished the 60 metres

2.The underlined word “subject” in Para. 1 refers to ________.

A. a person with a functional imbalance

B. a person chosen to be studied in an experiment

C. the subject one studies at school

D. the direction of walking

3.The purpose of writing the article is to ________.

A. prove that ears and eyes help us to walk straight

B. explain why we can hardly walk in a strictly straight line

C. point out the importance of noticing everyday science

D. give background information about a latest study
