2 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.

For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.

Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”

Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

3 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Sports Day was getting close in the school. All the children were very excited and were practicing for the big race. John, one of the fast runners of the school, was confident that he would win for he was not doing anything at all. “You have to work hard to come first in the race John. You are not practicing at all,” said John’s mother.

“Mom, you know how fast I am! Why should I waste my time running? Only I will win; no one else will win!”said John. “John, you may be right but talent (天赋) without hard work is not good at all. This laziness of yours will cost you greatly,” his mother warned him. John just laughed. He was so confident that he would win the trophy (奖杯) as no one else in his class was as fast as he was!.

Tim, a classmate of John, was also participating (参加) in the running race. He was not a fast runner. However, he practiced till late at night and had developed great endurance (持久力) to run the race.

There were a few days left for the Sports Day but John did not practice at all. On the other hand, Tim practiced day and night.

The Sports Day was almost around the corner but John was confident that no one could beat him and had not practiced at all. But Tim with his hard work had become a very great runner.

At last, the Sports Day arrived. All the students showed up on the ground to cheer their favorites. The coach blew the whistle (口哨) and everyone began to run toward the finishing line. It was so exciting. John and Tim left all the racers far behind. Both of them were neck to neck.

4 . More scientists are exploring cellular senescence(衰老)—a state in which cells(细胞)no longer divide. Senescent cells, which build up in older bodies, have a link to age-related conditions such as dementia(痴呆) disease.

Scientists are exploring drugs that treat senescent cells. But the most promising tool against the bad effects of senescent cells, experts say, is exercise.

Today, LeBrasseur, who directs a center on aging at Mayo, says exercise is “the most promising tool that we have” for good health in late life, and its power spreads to our cells. Research suggests exercise prevents the buildup of senescent cells, helping the immune(免疫的)system clear them and fight the cell damage that can affect aging.

Last year, LeBrasseur led a study that provided the first sign in humans that exercise greatly affected senescence. It cut signs in the bloodstream of the effects of senescent cells in the body.

After a 12-week exercise program, researchers found that older adults had cut signs of senescence and improved body strength, physical ability and reported health.   A recent study collects even more facts—in animals and humans—for exercise as a treatment to fight against senescence cells.

While such studies are not well-known outside scientific circles, many older adults connect exercise with youthfulness. Farmer Mike Gale, 81, put in a track and field throwing circle on his large farm in California. He and some of his friends throw the discus(铁饼) and use other exercise equipment. “I'd like to be competing in my 90s,” Gale says. “Why not?”

95-year-old Richard Soller says exercise keeps him fit enough to deal with what comes his way—including the discovery that his wife of 62 years had developed dementia. The two sometimes walk the streets of their neighborhood together, holding hands. “Do as much as you can,” he says. “That should be the goal for anyone to stay healthy.”

7 . At 81 years old, Jeanne Daprano is still pushing her body to the limit. She’s still running competitive races, breaking world records and taking on new challenges.“The thing I’m learning about aging is that it’s inevitable,” Daprano said.“I’m not going to escape it. There are two ways to go:You can either press on or give up.”

Daprano grew up in Iowa. Then, she moved to California. As a primary school teacher, she began running in order to keep up with her student.“I was known as a running teacher,” she said.“I had my students do fitness before we studied in the morning and then throughout the day.”Then she began running competitively with 5K and 10K road races before moving to the track. She is now the world record holder in the women’s 75-year-old age group 400 meters and 800 meters. “When I get to the final fi nish line, I want this body to be worn out. I’m not doing this to live to be 100. I’m doing this to be the best I can be today.”

After moving to Atlanta about a decade ago, Daprano met fitness trainer David Buer. Ever since, she’s been coming to his gym, where he tailors workouts for Daprano’s specifc needs.“When she came to me, she was pushing 70 years old,”Buer said.“I’ve worked with other individuals of Jeanne’s age, but she came to me with different goals. She had a unique drive and passion—not just a passion for fitness or athletics but for life in general.”

Last February, Daprano took on a new challenge: her first indoor rowing competition. In classic fashion, she broke the world record in the 80-to-84 age group, rowing 2,000 meters in 9:23:7. For those hoping to either start getting in shape or stay in shape for a long time, she offers this advice: Listen to your body. What are you passionate about? How are you going to keep physically fit and mentally fit? Start where you are. Don’t look ahead or compare yourself to somebody else.

9 . A 99-year old Australian swimmer appears to have broken a world record for his age group in the 50 m freestyle. The likely new world record holder, George Corones, clocked 56.12 seconds at an official event in Queensland—a new benchmark for the 100-104 age category. He faded the previous record of 1:31. 19, which was set by British swimmer John Harrison in 2014, by 35 seconds. It will now be affirmed by the sport’s governing body.

Corones, who is quailed for the record because he turns 100 in April, said he was “quite delighted” and “over the world” by the result. He said he had been overwhelmed by the “roaring” crowd on the Gold Coast on Wednesday. The event, in which he was the only entrant (新成员), had been specially staged for him to challenge the record.

Corones was a keen swimmer in his youth but only began to learn swimming again at the age of 80. He gave it up at the beginning of the World War Ⅱ, and he didn’t think he would have a swim of any description until he retired. Then he started swimming again for exercise.

Racing undeniably (不可否认的) challenged him physically, but it was manageable with preparation. On average he swims three times a week, and also fits in gym sessions. “At this age it takes a while to get going... you get exhausted much more easily, but if you do it properly, the rewards are astronomical,” he said.

Corones will challenge the 100 m freestyle record on Saturday night, believing he can beat the current mark of 03:23.10, which was also set by Harrison.

“I’m not a young man by any means, but I am rally looking forward to it and confident I can do it very well,” he said.
