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.

2 . All over the world people enjoy sports. Sports help to keep people healthy and happy, and to live longer.     1    They buy tickets or turn on their TVs to watch the games. Often they get very excited when their player or team wins.

Some sports or game go back thousands of years, like running or jumping. Chinese Kungfu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet.     4    Water-skiing is one of the newest in the family of sports.

Building team spirit.

Sports provide children with the important lesson of learning how to work in a team.     4     By working together they will learn each other’s strengths and weaknesses and will be better able to decide and work out the best plan for the team. This will without doubt help them in their future lives and jobs as well.

10 . For sports fans, there's nothing better than watching a live event on TV or at a sports venue（场地）. But there's nothing worse than that event being called off because of bad weather. Bad light, a waterlogged pitch （场地）or excessive heat can cause matches to be postponed. But according to the latest research, extreme weather might be disrupting （打乱） the sporting calendar more than ever in the future.

In one sport, golf, major tournaments like The Open, are already predicted to be victims of our changing climate. In the UK, an organization called The Climate Coalition says that golf courses such as St Andrews could be under water by the end of the century if sea levels rise even slightly. It told the BBC that its research predicts ^u cancelled football matches, flooded cricket grounds and golf courses crumbling into the sea.”

The threat to sporting fixtures （体育赛事）from climate change has been further highlighted in a new report, commissioned by the Rapid Transition Alliance. Writing about this for the BBC, Matt McGrath says that ”By 2050, it's estimated that almost one in four English football league grounds can expect flooding every year." This will mean fewer matches played, less opportunity to watch the beautiful game and reduced revenue （收入） from ticket sales.

Cricket also faces huge challenges globally as temperatures rise in places like India, Australia and the West Indies. The report says that stadiums in Adelaide and Perth will see a 60% increase in days with temperatures over 40°C over the next decade.

Of course, we know that the solution lies with reducing our carbon footprint. We could travel less to attend sports events, and reduce our waste when we do go. But this latest report finds that sports leaders are generally failing to address the issue seriously. However, because sport is universally popular and can be very influential, maybe it should be players, teams and their sponsors who promote a carbon-neutral message to help protect sporting venues - before it's ‘ game over’.

D．Some football grounds are expected to be flooded.

3. What can we learn from the passage?

A．Sports fans like watching a live event on TV better than at a sports venue.

B．Golf courses such as St Andrews could not be flooded if sea levels rise a little.

C．Cricket stadiums in Adelaide and Perth will get very hot over the next decade.
