Unit 2 Sports events 课时练1　2篇阅读＋1篇完形 阅读理解 A (2023年· 亳州联考) 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 so­called “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, along with many other chemicals. 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 they changed. However, when their endocannabinoids were blocked with a different drug, the runner’s high symptoms seemed to fade. “The long­held 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 a science blog. Similar studies are yet to be carried out on humans, but it’s already well 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 for 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 boost your mood if you have depression, and it’s 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 put on our running shoes. 【解题导语】　本文主要探究了影响运动者情绪高涨的因素。 1．What did scientists from German universities recently discover?

It is a challenge many disabled athletes face, unless someone agrees to be their eyes and ears. Newly formed group Achilles Brisbane pairs vision­and hearing­impaired(视觉和听觉受损的) athletes with people who would like to guide them. Jane Britt, president of Achilles Brisbane, who is vision­and hearing­impaired, said, “When we go out, it’s much less frightening to have someone beside us that has full hearing to listen for us and tell us what’s there.” Ms.Cullen and Ms.Britt meet up most Saturday mornings to take part in the five­kilometer park run. Their partnership is built on trust, but Ms. Britt said that it took time to develop. Ms.Britt said it took an unexpected storm for her to trust Ms. Cullen completely. “There was violent rain, my glasses were broken and we were
