1 . Students to Compete in 34th National Science Bowl

Thousands of students from middle and high schools across the country have committed themselves to extra study hours as they prepare to compete in the Department of Energy’s (DOE’s)34th National Science Bowl(NSB). These students are hard at work now to win their regional competitions, hoping to advance to the final competition.

The first regional event will take place on January 13th with high schools from the D. C. /Maryland area. Teams will face off in a fast-paced, question-and-answer format, and their knowledge in all areas of science and mathematics will be tested. Regionals will continue weekly until mid-March.

The winning team from each qualifying regional competition will be qualified to compete in the National Finals to be held in Washington, D. C. , from April 25-29, 2024, with all expenses paid by DOE. The national event consists of several days of science activities and sightseeing, along with the competitions.

In the National Finals, the top two teams will earn $5, 000 for their schools’ math and science departments. Schools ranking in the top 16 will receive $1, 000 for their science departments. But to many, the ultimate prize is simply the honor of winning the National Championship.

Today, the NSB annually draws more than 10, 000 middle and high school competitors. Since the first competition in 1991, approximately 344, 000 students have faced off in the NSB Finals. The 2024 competitors will follow in the footsteps of previous NSB contestants and will blaze a trail for students in science, math, and engineering.

3 . IOC president Thomas Bach was urged by several members Sunday to change Olympic rules on term limits and seek four more years as president through 2029.

Bach’s presidency is due to end in 2025—a 12-year maximum agreed in anti-corruption (反腐) reforms passed after the Salt Lake City scandal (丑闻) broke in the 1990s. However, citing the recent years of global crises, several of the 99 International Olympic Committee members opened their annual meeting Sunday suggesting they needed more of Bach’s leadership. The Olympic movement needed “to go through this period of hardship with a president who has proved his courage,” said the Algerian leader of African Olympic bodies, Mustapha Berraf.

Though Bach has never publicly sought a term limit-lasting third time, the option has been spoken of in international sports circles since he was re-elected in 2021 at a meeting. The IOC gives its president a first term of eight years.   Bach neither encouraged nor dismissed the proposal though he noted the presidential term limit is included in the IOC’s book of rules and principles. “I’m very loyal to the Olympic Charter,” the German lawyer said.

Extending Bach’s term would need a proposal submitted ahead of an annual meeting, known as the Session. The next is scheduled in July in Paris on the eve of the 2024-Summer Games.

A diplomatically expressed counter to extending Bach’s presidential term was suggested by gymnastics federation president Morinari Watanabe, who has been considered as a possible IOC leadership candidate. “Sports organizations must follow rules and have high integrity under good governance,” Watanabe suggested. “Sports demonstrate discipline and the spirit of fairness to society.”

Consideration on other candidates to succeed Bach has also included two of the IOC’s four vice presidents, Nicole Hoevertsz of Aruba and Juan Antonio Samaranch Jr. of Spain, plus Zimbabwe sports minister Kirsty Coventry, who is widely seen as a favored successor of Bach.

5 . This was the big game. The boys were _________ and excited. It was a clear night, and my son, Andy’s baseball team, which had _________ all year, had shocked the better teams by making it to this championship game. The atmosphere was _________: the other team’s slugger (强击手), a big kid, was like a snake, dangerous and ready to _________.

Nervously, I looked out Andy’s way. I was _________ to see Andy looking straight up at the night sky! Obviously he wasn’t _________ on the game. I was horrified that he wouldn’t even know the ball was coming.

“Come on, Andy. _________ out there,” I said to myself.

Thank goodness, a big kid in the other team made a mistake. Andy and I had been _________ and our team still led by one run.

Andy ran up to me at the _________. I was about to ____________ him when he said loudly, “Did you see that shooting star?”

Andy’s eyes were glowing (发光) with ____________. I paused.

“Yes,” I said. “Well, one inning (局) to go. Hit a home run (全垒打)!”

“Okay!” said Andy, and he ran back to his ____________.

I suddenly realized it was nice that my son would take time out to ____________ the wonder and beauty in life. You might be surprised by the beauty you can find when you least ____________ it. Andy hit a triple (三垒打) in that last inning. But I still wish I had ____________ that shooting star, too.

6 . Rushing down the path, the traceur (跑酷者) is on the lookout for his next obstacles such as fire escapes, walls, or fences. As soon as he realizes a massive brick wall stands between him and where he wants to be, he unintentionally grabs on the wall with his hands and lifts himself to stand on top of it. His next move is a jump that lands him back on solid ground; however, noticing that he is unstable, he rolls to avoid injury.

Traceurs are athletes who perform remarkable gymnastics actions in urban environments. Serious traceurs are fascinated not just by the physical challenges of Parkour, but by its philosophy. Those who learn to excel at Parkour claim to develop not just physical fitness, but increased self-confidence and critical thinking skills, as they train themselves to find ways around every obstacle in their paths.

Because of these philosophical foundations, Parkour is often described by traceurs as more of a lifestyle or an art form than a sport. Passionate traceurs are determined to keep Parkour from becoming a competitive attempt. Competition, they argue, devalues the philosophical theory behind Parkour. People who practice Parkour should be more concerned with their relationship to the environment than with a ticking clock, a score, or a cheering crowd. Furthermore, traceurs should work with each other to improve confidence, awareness, and unity. Competition, they argue, only brings about feelings of conflict and disharmony.

While Parkour purists suggest that the philosophy behind Parkour helps to limit injuries, they must remember that not everyone who tries to leap over a mailbox is an experienced traceur trying to get in touch with his or her environment. Adolescents attempting to carry out these acrobatic (杂技的) skills could severely injure themselves. So while newcomers to Parkour might be eager to investigate this art of movement, it would be wise for them to remember the physicality behind the philosophy. After all, philosophy is not much good to a broken leg.

7 . When it comes to lowering blood pressure, studies have typically shown that aerobic (有氧的) exercises are best. Recent research suggests another type of physical activity is worth including as an effective tool to prevent and treat high blood pressure.

Exercises that engage muscles without movement, such as wall squats and planks, may be best for lowering blood pressure, according to a large study published in July, 2023 in the British Journal of Sports Medicine.

This type of training is known as isometric exercise, according to the Mayo Clinic. Isometric muscle action happens when muscles contract but do not visibly change length, and the joints involved don’t move, facilitating stability of the body. Isometric exercises can be done with weights or without, just relying on the body’s own weight.

“These findings provide a comprehensive data-driven framework to support the development of new exercise guideline recommendations for the prevention and treatment of high blood pressure,” said study coauthor Dr. Jamie O’Driscoll in a news release.

The researchers looked into randomized controlled trials that had reported the effects of exercise interventions, lasting two or more weeks, on blood pressure between 1990 and February 2023. From a review of 270 trials with 15,827 participants, the researchers found that among HIIT (high intensity interval training), isometric exercise, aerobic exercise, dynamic resistance training and a combination of the latter two, isometric exercise led to the greatest reductions in blood pressure.

It’s also important to note that there are other lifestyle changes as well as exercise that can benefit your blood pressure. These include keeping to a healthy weight, eating a balanced diet, cutting down on salt, not drinking too much alcohol and ensuring that you continue to take any prescribed medication.

More research is needed to determine exactly why isometric exercises might be better for lowering blood pressure than other types of training, the authors said.

In my old school days, running     1    (consider) boring and painful for me. When I started to work, I realised exercise should be part of my lifestyle. Later, running became my career. Over the years, I     2    (coach) many running teams. Needless to say, running has its benefits. It is believed     3    running can decrease the risk of death. So are you currently not doing it? I encourage you to start now.
