1 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.

But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.

According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.

To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.

“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.

Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.

It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

7 . The secret to living longer could be as simple as picking up your walking pace, according to a new study. Researchers from the University of Sydney found that walking at a brisk(快的) or fast pace was associated with a risk reduction of 24 percent for any cause of death.

This effect was even more obvious in older age group, with fast walkers over the age of 60 reducing their risk of death by a surprising 53 percent. Professor Emmanuel Stamatakis, who led the study, explained, “A fast pace is generally five to six kilometers per hour, but it really depends on a walker’s fitness levels; an alternatives indicator is to walk at a pace that makes you slightly out of breath or sweaty.”

In the study, the researchers looked at the results of 11 surveys from 1994 to 2008, in which participants recorded their walking pace, as well as age, sex and BMI. The analysis showed that walking at an average pace was associated with a 20 percent risk reduction for all-cause mortality(死亡率) compared with walking at a slow pace, while walking at a brisk or fast pace was associated with a risk reduction of 24 percent.

The researchers hope the findings will encourage the development of public health message about the benefits of walking pace. Professor Stamatakis added, “These analyses suggest that increasing walking pace may be a straightforward way for people to improve heart health and risk for premature mortality--- providing a simple message for public health campaigns to promote.

“Especially in situations when walking more isn’t possible due to time pressures or a less walking-friendly environment, walking faster may be a good option to get the heart rate up--- one that most people can easily add to their lives.”

1. Who benefit most from walking fast?

A．Cancer sufferers.	B．The elderly.

8 . The idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play plays an important part in keeping you healthy.

Treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.

Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it’s for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.

1. What can laughter increase according to the author?

A．Cognitive ability	B．Good relationships
C．A sense of humor	D．Happiness and trust

2. What does the author think the old should do?

A．They should have a good rest.

B．They should play like children.

C．They should prevent cognitive falling.

D．They should take part in physical play.

Exercise could not only benefit your body, but also improve your memory, researchers found     1    (recent).

In their paper, researchers in the United States and Japan    2    (introduce) their experiment and conclusion.

Scientists invited 36 volunteers    3    were in their early 20s to do 10 minutes of light exercise before taking a memory test in which they     4    (show) pictures like broccoli(西兰花) or picnic baskets and asked to recall them later. The same experiment was repeated with the same group of volunteers without exercising. “ The memory task really was quite     5    (challenge),” said Michael Yassa, co-author of the study. “ We used very similar items to see if they would remember     6     it was this exact picnic basket versus that picnic basket.”

Researchers also scanned brains of some of the participants during the experiment.

They found increased communication between parts     7    (involve) in the storage and recollection of memories in brains of those who had exercised.

This suggested that just 10 minutes of light exercise might have a positive effect     8     memory power.

As all     9    volunteers in the experiment were relatively young, researchers are still working     10    (look) at the influence of light exercise on older people. “Our main goal is to try to develop an exercise way that can be used by older adults who might have disabilities,” said Yassa.
