On February 10, 2024 ambitious young scientists flooded Brown University’s classrooms and laboratories, ready to put their knowledge to the test at the 7th Annual Brown Science Olympiad tournament, which provided a     1     (true) enriching and enjoyable experience for all involved.

The STEM competition welcomes nearly 1, 000 high schoolers from across New England.     2     (feature) a lineup of 23 diverse challenges, the single-day academic tournament integrates written assessments with hands-on design and build tasks. Each challenge     3     (score) individually, with points awarded based on performance, accuracy and completion of tasks. Teams win by accumulating (累积) the highest total score across all 23 challenges in the tournament.

Contestants get     4     (them) involved in various scientific disciplines, from fundamental subjects like biology, chemistry and physics to     5     (specialize) areas such as astronomy and robotics. Throughout the event, students engage     6     a series of activities in a day filed with curiosity, creativity, exploring the     7     (wonder) of science and pushing the boundaries of their intellectual capabilities.

But the Brown tournament isn’t just about becoming a strong competitor. It also offers a platform for young scientists     8     (wander) Brown’s campus. “With the tournament, you can get an insight into college life and     9     great understanding of the whole college experience,” Golditch a contestant, said. “Participating in the Science Olympiad has been the most valuable experience     10     allows us to explore fun science concepts,” added Golditch.

2 . 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.

6 . 听下面一段较长对话，回答以下小题。

7 . Despite what most people might think, you really don’t need much time to work out. In fact, even ten to twenty minutes of challenging exercise a few times a week is enough to burn fat, build muscle, boost strength, and contribute to a healthy, active lifestyle.     1    

But sometimes, the resistance isn’t really about the actual time the workout takes. It’s about the energy it takes to get ready for it. Maybe your stress levels are over the top, or your energy levels have been so low that you keep talking yourself out of a workout. Or maybe you just don’t want to get all sweaty and have to take a shower afterward.     2     In such fast-paced life, we’re all struggling. But when it comes to exercise, being healthy and fit isn’t as black and white as the fitness world tries to make it seem.     3     Doing something is always better than nothing when it comes to movement. Micro workouts, like getting out for a fifteen-minute walk instead of doing the strength training workout, are significantly better than doing nothing at all.

    4     They are time-saving, since they can be done in seconds or in as little time as 15-20 minutes. They require minimum space and equipment. Many can be done at home, in the park, or even while waiting in the checkout line. They are also money-saving as these can be done without a gym membership, coach, trainer, or class instructor.

So in order to maintain a healthy lifestyle, make time to move.     5     If all the movements like push-ups and pull-ups add up, you will still get many of the same benefits of a longer, harder workout.

8 . Today, many people are turning to social media for their fitness routines, with TikTok, one of the most popular platforms. Indeed, its fitness category has some 300 billion views. But are the posted works, exercises and challenges really safe and effective?

While fitness influencers can encourage people to become more physically active, which is a positive, the quality and accuracy of their content is a concern, according to a 2023 review in Frontiers in Public Health.

“There are a lot of unsustainable and unrealistic workouts on TikTok, and even some dangerous advice,” said Jess Brown, a certified personal trainer in Westchester, New York. “What’s more, much of the fitness information on TikTok isn’t backed by science or posted by fitness professionals. The workouts are usually generalized to anyone, too, and don’t take into account your health, your family history, your flexibility, your range of motion—the list goes on,” said Monica Jones, a certified personal trainer in Washington, DC.

One of the more popular TikTok fitness trends involves developing your abdominal muscles. These challenges often show an influencer doing one exercise or series of movements that, if repeated daily for a week or two, is promised to result in a sexy six-pack. “No way,” Brown said. “We’ve proven again and again that spot reduction isn’t a thing.”

“Unfortunately, there will always be trends centered around getting fast results, because those grab people’s attention. But it’s important to look at your fitness and health as a lifelong journey, not something you can achieve within 10 to 90 days,” Jones said.

How can you separate quality workouts from dangerous ones? First, check the information of the posters. They should be certified fitness professionals who have experience working with people. You also want a coach who emphasizes improving strength and health, not one who focuses on body type. A quality influencer should encourage mental well-being, self-care and the importance of listening to your body in addition to physical fitness.
