1 . The damage that aging does to a body extends all the way down to the cellular level. But the damage increased by cells in older muscles is especially severe, because the cells do not reproduce easily and they become weaker as their mitochondria (线粒体), which produce energy, reduce in energy and number. A study, however, suggests that certain sorts of exercise may remove some of what time can do to our mitochondria.
Exercise is good for people, as everyone knows. But scientists have surprisingly little understanding of its cellular impacts and how those might vary by activity and the age of the exerciser. So researchers recently conducted an experiment on the cells of 72 healthy but sedentary (久坐的) men and women who were 30 or younger or older than 64. After baseline measures were established for their aerobic (有氧的) fitness, their blood-sugar levels and the gene activity and mitochondrial health in their muscle cells, the volunteers were randomly assigned to a particular exercise program.
Some of them did weight training several times a week; some did interval training three times a week on exercise bicycles; some rode exercise bikes at a appropriate pace for 30 minutes a few times a week and lifted weights lightly on other days. A fourth group, the control, did not exercise. After 12 weeks, the lab tests were repeated. In general, everyone experienced improvements in fitness and an ability io regulate blood sugar.
But more unexpected results were found in the biopsies (活组织检查) muscle cells. Among the younger subjects who went through interval training, the activity levels had changed in 274 genes, compared with 170 genes for those who exercised more appropriately and 74 for the weight lifters. Among the older group, almost 400 genes were working differently now, compared with 33 for the weight lifters and only 19 for the appropriate exercisers.
It seems exercise could help contain the decline in the cellular health of muscles associated with aging, especially if it was intense, says Dr. Sreekumaran Nair, the study's senior author. In fact, older people's cells responded in some ways more strongly to intense exercise than the cells of the young did - suggesting, he says, that it is never too late to benefit from exercise.

2 . Do you like running enough to make it a habit? Tierney Wolfgram does; she has made running a lifelong career and isn’t stopping.
In February, the 16-year-old from Woodbury High School, Minnesota, US, competed at the 2020 US Olympic Trials.
She finished the marathon (42.195 km) with a time of 2:42:47 as the youngest competitor in the race and ranked 76th out of 390 runners.
However, the cross-country (越野的) season was postponed to winter because of the coronavirus pandemic. So she jumped at the opportunity to train for another race — the Parkway Marathon in California.
In November, Wolfgram, who turned 17, broke the Women’s American Junior marathon record with her time of 2:31:49. The old record was 2:34:32, which had stood since 1984.
“I’m absolutely stunned,” said Wolfgram’s assistant coach, EmKay Sullivan. “I knew she was going to break it, but she really showed out!”
During the run, Wolfgram once hit a wall pretty hard, but she overcame it to finish. “I guess I can say I gave it my all,” she told Runner’s World.
“I When I finished all was thinking was I was super happy,” Wolfgram said.
This was only her third marathon. In 2018, when Wolfgram was 15 years old, she ran her first marathon just because she wanted to see if she was capable of doing it. “I believed that I would get faster as the distances got longer… and I’m still gad that I did it.”
When preparing for that first marathon, she ran up to 120 miles (about 190 kilometers) per week.
Although her parents didn’t have any background in running, they helped Wolfgram train. At first, her dad would take her out in the morning and run about l3 miles. The distance would gradually increase each day. On top of her runs in the morning, she would do cross-country practice after school.
After the Parkway Marathon, Wolfgram shifted to recovery mode. She and her team now prepare for the indoor track and cross-country race this winter.
As for the marathon, Wolfgram will consider attending the Olympics Games in 2024 after it’s scheduled.

4 . US Open Championships
The US Open has been in existence for more than 130 years. The first tournament was held in 1881 at the Newport Casino. It was called the US National Singles Championship. Entry was limited to only those clubs which were members of the United States National Lawn Tennis Association, and the competitors were all male, competing in both singles and doubles. Richard Sears won the men's championship and he went on to win the next six men's singles championships.
The Wimbledon
In 1875, the All England Croquet Club was troubled financially due to declining membership. A new sport called lawn tennis was gaining fast in popularity and taking away the members. Two years later, a new roller was needed for maintaining its lawns so the club proposed to hold a tournament to raise money. Twenty-two players entered that first Wimbledon tournament which was won by Spencer Gore in straight sets over W. C. Marshall. Two hundred spectators each paid a shilling to watch the final game, enabling the club to buy the needed roller plus some extra cash.
The French Open
The very first French Championship was way back in 1891, and the tournament has since grown into one of the four tennis Grand Slam tournaments we know today. The first competition was a one-day national championship which was won by a British. The competition was poorly attended by world class players. It took 24 years before it became fully international and an accepted tennis grand slam event. After the First World War, French tennis was achieving stature. Suzanne Lenglen was the predominant French player, winning the championships six times between 1920 and 1926.
The Australian Open
The very first tennis tournament ever played in Australia was held in January 1880, on the courts of the Melbourne Cricket Club. In 1905, the Australian Open was established as the Australasian Tennis Championship and was played at the Warehouseman's Cricket Ground in Melbourne. It became the Australian Championship in 1927 and the Australian Open in 1969. Women's events were added in 1922.

7 . New events and changes of junior golf competition calendar
New events
Notah BegayⅢ Junior Golf National Championship
What does a junior golfer aim to pursue? One thing is to be noticed, ideally by a college coach. A remarkable opportunity will be offered by the Notah BegayⅢ Junior Golf National Championship to its participants: an event broadcast by Golf Channel. Players aged between eight and 18 can compete in the new event; information about where and when it will be held will be released later.
Barbasol Junior Championship
Beginning the career in the PGA Tour is something that a junior golfer tends to dream of. The Barbasol Junior Championship, which is scheduled to take place between June 29 and July 2 at Keene Trace Golf Club in Nicholasville, Kentucky, will provide such an opportunity. Boys under 19 years old will qualify for this new 54-hole event, and the winner will be awarded a spot at the PGA Tour's Barbasol Championship in July.
Changed events
Thunderbird International Junior
The dates of the AJGA's Thunderbird International Junior have to be changed since the NCAA Championships move to Grayhawk Golf Club in Scottsdale, Arizona, for the next three years. Generally, the Thunderbird is played at the end of May. However, this year it is scheduled on different dates for the first time, from April 9 to 12, which means, of course, that the finish date is on Masters Sunday.
Gator Invitational
Junior golf intends to prepare for the following college golf. If this is the case, then it is crucial to simulate the higher-level experience as much as possible. Because of that, the Gator Invitational, as a junior boys' event, has made a significant decision on becoming a 54-hole event by adding a round this year. The new version will be played from March 13 to 15 at The Country Club of Jackson in Jackson, Mississippi.
1. Which event can be watched on TV?| A．Notah BegayⅢ Junior Golf National Championship. | B．Barbasol Junior Championship. |

8 . Sports fandom is about more than just entertainment. It can boost your self-esteem (自尊) and make you happier — and you don’t have to root for the winning team to gain the benefits.
Being a sports fan is a “very psychologically healthy activity,” says Daniel Wann, professor at Murray State University whose research program centers on the psychology of sport fandom. Fandom connects us to other like-minded people, which satisfies our human need for belonging, he says.
These relationships are significant: People who identify as sports fans have higher levels of self-esteem, lower levels of loneliness and tend to be more satisfied with their lives compared to those who aren’t interested in sports, Wann says. Fans tend to have more access to social support, help and resources as well. Research suggests that when people have support from their communities, they have better health.
Beyond bonding, fans get to enjoy the psychological benefits of winning, even if they have nothing to do with the players or games, says Stephen Reysen, associate professor at Texas A&M University-Commerce who studies identity and fandom.
“Individuals feel that the fan interest (in this case a sport team) is a part of them,” Reysen says. “So when the team is winning, you feel like you are winning even though you are not a player.”
Of course, teams sometimes lose.
So, why do people continue to put their faith behind teams that tend to lose? People who feel a strong psychological connection to a team are more likely to root for a team when they’re having a losing season, Reysen says.
“Sports fandom has nothing to do with the outcome of a game,” Wann says. For example, if a pizza restaurant continually got your order wrong, you’d likely switch to a more reliable one. But because being a fan is so central to people’s identities, people are willing to accept defeat and continue to be loyal to a team.
Being part of a fan community can also help people cope with losses. A 2019 study found that watching a football game with other fans helps to ease the negative psychological effects of losing.
“For fans of the losing team, sharing the pain may have protected them from losing self-esteem,” Silvia Knobloch-Westerwick, co-author of the study and professor of communication at The Ohio State University said in a release.
1. According to the passage, why do sports fans feel happier?| A．Because they could gain the benefits from the winning team. |
| B．Because they can share pains and happiness with people who have the common interests. |
| C．Because they could have a low level of self-esteem. |
| D．Because most of them are optimistic. |
| A．Sports fans have support from their favorite teams. |
| B．Sports fans have higher levels of loneliness. |
| C．Sports fans are likely more content with their lives. |
| D．Sports fans tend to compare themselves to those who aren’t interested in sports. |
| A．display their identities |
| B．have a boost of self-esteem |
| C．not support the team any more |
| D．have a negative psychology period |
| A．Being part of the team. |
| B．Ordering a pizza in a different restaurant. |

| B．Sports fans have higher self-esteem and are more satisfied with their lives. |
| C．Sports fans always put their faith behind their favorite teams. |
| D．Sports fandom has nothing to do with the outcome of a game. |
