We already know that exercise is good for our bodies. Daily exercise fights the loss of muscle tone and flexibility that tends to increase slowly with age. And it turns out that it has the same fountain-of-youth effects on our brains.
Studies show that over time our minds also become less nimble. We lose the ability to process new information or switch between mental tasks quickly — and now we know why.
A recent study examined nearly 100 individual studies on exercise and brain function and discovered exercising an average of 52 hours over six months is “associated with improved cognitive (认知的) performance in older adults with and without cognitive damage.” The type of exercises that are beneficial include aerobic, strength-training and mind-body exercises like yoga or tai chi.
In previous studies, researchers from Japan’s University of Tsukuba wanted to explore this idea by looking at the effect of exercise on the weakening of the brain. They tested the oxygen ability of 60 Japanese men between the ages of 64 and 75 who did not show any signs of dementia (痴呆) or other mental symptoms. Next, they looked at the brain activity of each man as he completed a mental task. They found that the fitter a participant was, the less brain power he used to complete the tasks when compared with his out-of-shape peers, which made him more efficient.
Although much research is focused on how exercise may benefit an aging brain, exercise offers brain health benefits at almost any age, and this includes children. A review of 14 studies showed that more physically active schoolchildren do better academically. Exercise actually causes your brain to grow in size. So get moving and keep moving for best results.
1.The underlined word “nimble” in Paragraph 2 most probably means__________.
A.dull-witted B.single-minded
C.absent-minded D.quick-witted
2.What can we infer about the participants’ less-active peers?
A.They had significant brain advantages.
B.Their brains were younger than their age.
C.Their cognitive performance would decline.
D.They had a quick mind when doing the task.
3.How does the author support his idea?
A.By making comparisons.
B.By analyzing study results.
C.By describing the processes.
D.By telling peers’experiences.
4.What’s the main idea of the text?

B.Exercise can benefit your brain health.
C.Exercise is especially good for dementia.
D.Exercise may lower your risk of mental problems.

We all know that regular exercise is vitally important for both a healthy mind and body. Research has shown that just five minutes of exercise in a “green space” can help people to keep mentally healthy.
Let’s take a look at some ways to get close to nature and make them a part of your regular exercise routine.
Get on your bike
Cycling is a cheap, easy and fun way to get some good exercise in the outdoors. Try leaving your car at home and cycling to work one day, if that’s possible. Or get the family together and go on a weekend bike ride. Check out the local cycle paths before you go, and plan a safe route. Make sure you take some healthy snacks with you to keep your energy levels up.
Try some outdoor yoga
Practising yoga can be great for reducing anxiety and aiding relaxation, so why not take your yoga mat and try out some asanas (yoga postures) in the open air? Yoga is great for stretching tight muscles and increasing flexibility as well as improving mobility, control and breathing. Why not finish your practice with some quiet meditation to further calm the mind?
Go running
Instead of spending hours on the treadmill(跑步机), grab a friend and go off for a jog around your local park, or some nature trails. If you are used to running on a treadmill, you may find it harder at first, so make sure you have some good, supportive running shoes. You could also find out where your nearest Parkrun is. They are open to everyone, free, and are safe and easy to take part in.
Join a conservation(保护) group
Joining a conservation group is a great way of keeping fit while helping the world around you. Do some research into what’s going on in your local area and you could find yourself helping to plant trees, clear up rivers and so on. You never know it could lead to new friendships, as well as the knowledge that you are doing something productive for your local area!

We all know that exercise is good for your health. But some kinds of exercise may be better than others.
Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer. Researchers say it is not important how far you run. It also does not matter how fast or even how often you run. As advertisements for the running shoes Nike say, “Just Do It.”
Recently researchers studied more than 55,000 adults. About one-fourth of the adults reported running regularly. The study found these runners were considerably less likely than non-runners to die of any form of disease, including heart disease. In fact, the runners lived, on average, three years longer than the non-runners.
This study lasted 15 years. During that time, more than 3,400 of the individuals died. About 1.200 of the deaths were linked to heart disease, hear, attack or stroke.
One of the researchers is a man named D.C. Lee, a professor of Iowa State University Compared to non-runners, he said, runners showed a much lower risk of dying from some diseases. “Compared to non-runners, runners showed 30 percent lower risk of death by any causes, including heart attack, stroke and cancer. Also, runners compared to non-runners showed 45 percent lower risk of death by cardiovascular diseases(心血管疾病), including heart attack and stroke.”
D. C. Lee and the other researchers found that speed, distance and how often one runs made little difference in reducing the risk of death. The runners in the study averaged between 10 and 16 kilometers per hour. Mr Lee said slower runners and those who only ran once or twice a week were helped nearly as much as those who ran faster and further. “And also we looked at the inning over time and we found that persistent runners(over six years)showed the biggest benefits, as well.”
1.What does the author mean by quoting Nike’s ad “Just Do it”?
A. It’s time for you to start running.
B. Nike has always kept its promise.
C. You have to run as fast as possible.
D. Running does you good whatever its form.
2.The researchers got the results of their study mainly by ________.
A. analyzing data B. having interviews
C. doing experiments D. doing field survey
3.What can we learn from Paragraph 5?
A. Heart disease is the biggest killer of mankind.
B. Runners are generally healthier than non-runners.
C. Heart disease has killed more people than cancer.
D. Running greatly reduces the risk of cardiovascular disease.
4.What can we know according to Mr Lee?
A. Slower runners and faster runners benefit equally from running.
B. You can benefit most if your speed is over 10km per hour.
C. You must control your speed properly while running.
D. The further you run, the more benefits you will get.

It comes as no surprise that exercise is good for your health. Positive changes happen to your body before, during, and after a workout. 1.
Build up your body
There are quite a few scientific reasons to do strength training. It makes muscles (肌肉) bigger and bones stronger, thus lowering the risk for certain diseases. Running is an easy but effective way to help build your muscles. 2. But a recent study found that a short run can benefit the legs in the short term. And for now, experts say running has more benefits than risks.
Improve your brainpower
Exercise can help your brain, not just your body. Physical activity helps brain cells (细胞) grow. 3. That’s because physical exercise quickly increases a person's heart rate and carries more blood to the brain, improving the brainpower.
Establish a mind-body connection
Too much stress can lead to inflammation (炎症).4. But simple mind-body exercises like yoga can not only reduce inflammation but also lower the risk of depression. New research shows they can even change your genes to fight off poor health. Research proves that even just 15 minutes a day of practicing mindfulness seems to do the trick.
5. National guidelines recommend more than two hours of physical activity each week. But science says people who pack that amount into one or two days get about the same benefits. Either way, get moving is the key!
A.It is the body’s painful response to injury and overuse.
B.Mindful exercises can improve your long-term well-being.
C.Then what is the proper amount of exercise you should take?
D.And moving more appears to lower the chances of memory loss.
E.Recent research shows more detail about the benefits of exercise.
F.Exercise can also help people deal better with anger and feel happier.
