Last summer, Hilda worked as a volunteer with dolphin trainers at a sea life park. Her job was to make sure the tanks were free of any items so that the trainers could train the dolphins to fetch specific items. However, one day after cleaning, one of the dolphins, Maya, presented Hilda with a candy wrapper from the tank. When Katherine, the trainer, saw this, she blamed Hilda for her carelessness. Upset but not discouraged by this event, Hilda decided to do some spying on Maya.
The next morning, Hilda arrived at the park early. She put on her scuba gear (水下呼吸器) and jumped into the tank for her usual, underwater sweep. Finding nothing in the tank, she climbed out of the water just in time to see Katherine jumping in on the other side. After what happened yesterday, Hilda knew what she was doing. She watched as Katherine performed her underwater search, but Hilda wasn’t surprised when she surfaced empty-handed.
During the tank sweeps, Maya had been swimming playfully, but now the dolphin stopped suddenly and swam to the back part of the tank where the filter (过滤) box was located. She stuck her nose down behind the box and then swam away. What was Maya doing back there? Hilda wondered. She jumped back into the water and swam over to take a look behind the box, and her question was answered. Hilda then swam across the tank following Maya’s path and emerged from the water to find Katherine removing her scuba gear. As Katherine turned around, her mouth dropped open. There was Maya at the edge of the tank with a comb (梳子) in her mouth waiting for her treat.
“Maya! Where did you get that?” demanded Katherine, taking the comb and throwing her a fish. “I know where she got it,” declared Hilda climbing out of the tank with a handful of items still wet from their watery, resting place. “What’s all this?” Katherine asked, obviously confused.

3 . Common Mistakes New Runners Make
Running is a great way to get in shape and just about everyone can do it. However, many make a number of common mistakes, which can interfere (妨碍) with training or lead to injury.
·Doing too much too soon
One of the biggest mistakes new runners make is doing too much too soon. Slowly easing into a training program will help reduce the risk of injury, so you can continue on with your new running routine
·
Beginners might think they need to run every day (or nearly every day) to meet their fitness or weight-loss goals, but this couldn’t be further from the truth. Running is a high-impact activity which can be really hard on your body. So it’s important to give your body a rest between workouts.
·Not wearing the right equipment
•Running through pain
A.Not taking rest days |
B.If you’re just starting out |
C.Comparing yourself to others |
D.Running can be uncomfortable at times |
E.It’s important not to use the same muscles |
F.While it may be true that you don’t need expensive equipment to take up running |
G.Experts suggest increasing your running distance by no more than 10% each week |
4 . A new study suggests that science role-playing may help tighten the gender gap in science, technology, engineering, and math(STEM)education and careers for women simply by improving their identity as scientists.
Frustrated by the gender gap in STEM, in which some fields employ at least three times more men than women, Cornell graduate student Reut Shachnai wanted to do something about it. Reut said the idea to help foster young girls’ interest in science came to her during a lecture in a class she was taking on Psychology of Imagination.
Reut designed an experiment to test if assuming the role of a successful scientist would improve girls’ persistence in a “sink or float” science game. The game itself was simple yet challenging: a computer screen projected a slide with an object in the center above a pool of water. Kids then had to predict whether the object would sink or float.
She studied 240 four -to -seven -year -olds, because this is around the time kids first develop their sense of identity and capabilities. They were divided into two groups. Children in the “story” group learned about the successes and struggles of a gender -matched scientist before playing the game. Boys heard about Isaac Newton and girls were told about Marie Curie. Children in the “pretend” group were told to assume the identity of the scientist they just learned about.
All kids played at least one round of the game. No matter what group they were in, girls got the answers right just as often as boys -nearly 70% of the time. Boys, however, didn’t really benefit from the stories or make-believe. Besides, girls pretending to be Dr. Marie persisted twice as long at the sink-or-float game, playing just as much as the boys did.
Reut’s teacher Tamar Kushnir said, “Rather than merely hearing about role models, children may benefit from actively performing the type of actions they see role models perform. In other words, taking a few steps in the role model’s shoes, instead of merely observing her walk.”

5 . Bumble bees (大黄蜂) play, according to new research led by Queen Mary University of London. It is the first time that object play behaviour has been shown in an insect, adding to evidence that bees may experience positive feelings.
The researchers set up numerous experiments to test this, which showed bumble bees went out of their way to roll wooden balls repeatedly despite there being no apparent motivation for doing so. The study also found that younger bees rolled more balls than older bees and that male bees rolled them for longer than their female ones.
The study followed 45 bumble bees. Individual bees rolled balls between 1 and, impressively, 117 times over the experiment. The repeated behaviour suggested that ball-rolling was rewarding. This was supported by a further experiment where another 42 bees were given access to two coloured rooms, one always containing movable balls and one without any object. When tested and given a choice between the two rooms, neither containing balls, bees showed a preference for the colour of the room previously associated with the wooden balls.
The experiments removed any idea that the bees were moving the balls for any greater purpose other than play. Rolling balls did not contribute to survival strategies and was done under stress-free conditions.
The research was based on previous experiments, which showed that bumble bees could be taught to score a goal by rolling a ball to a target in exchange for a sugary food reward. The new research showed the bees rolling balls repeatedly without being trained and without receiving any food for doing so — it was spontaneous.
Professor Lars Chittka said, “Play is thought to contribute to the healthy development and maintenance of an animal’s cognitive (认知) and motor abilities, which may make for their searching for food and is considered an important aspect of animal welfare. The finding shows insect minds are far more complex than we expect. We need to do all we can to protect insects.”

G.Remember, there are some strangers simply coming over to browse your goods. |
7 . While most teenagers are simply hoping to get their driver’s license, 17-year-old Mack Rutherford has had far higher goals. The ambitious teen sought to become the youngest person to fly solo around the world. After five months and a day, Rutherford successfully achieved the incredible feat.
In March 2022, 16-year-old Rutherford took off on his adventure. He flew a Shark, a high-performance ultralight (超轻型的) aircraft. His journey around the world tested him in the skies through monsoons (季风) and extreme temperatures. Rutherford’s longest flight on this journey was from Japan to the U. S., which took him 10 hours over water. The highest altitude he had to face was 12, 500 feet over Mexico. He flew across four continents, 30 countries.
After everything, Rutherford landed safely in Sofia on August 24. He arrived home to discover he’d broken two Guinness world records: he is the youngest person ever to fly around the world solo, and also the youngest person to do it in an ultralight aircraft. But he surprised the world by becoming the youngest pilot ever at age 15, when he received his microlight pilot’s license.
This incredible achievement at such a young age is certainly worth celebrating and his family might be the perfect people to fully appreciate it. Rutherford’s father is a professional pilot. This sparked an interest in aviation (飞行) for the young Rutherford since he was 11. And Rutherford’s sister, Zara Rutherford, recently completed a similar solo journey and holds her own world record as the youngest female pilot to complete a solo flight around the world.
“I’m very happy to complete my five-month journey around the world,” Rutherford said. “It took a bit longer than it was supposed to, but everything is fine. I’m trying to show that young people can do something special and make a difference; just follow their dreams and they’ll eventually come true.”
1. Which word can best describe Rutherford’s flying journey?A.Smooth. | B.Tough. | C.Tiresome. | D.Thrilling. |
A.His ambition different from his peers. | B.His accomplishment of a solo journey. |
C.His high-performance ultralight aircraft. | D.His microlight pilot’s license at age of 15. |
A.Through his father’s influence. | B.From Zara Rutherford’s support. |
C.By imitating most teenagers’ dreams. | D.Out of his talent for solo flights. |
A.Learn to fly as early as possible. | B.Take heart to achieve their dreams. |
C.Do special things to change the world. | D.Travel the world to enrich their experience. |

10 . Broadcom MASTERS awards $100, 000 in prizes, inspiring and rewarding the Nation’s next generation of scientists, engineers, and innovators. The competition took place in Washington, D. C.. It’s aimed to test participants’ 21st Century skills of critical thinking, communication, creativity and cooperation in each of the STEM areas.
Elizabeth Shen, 14, Cary, N. C., demonstrated both vision and promise as an innovator, in the spirit of radio inventor Guglielmo Marconi. Elizabeth drew inspiration from the way many flowers grow to design a system for better managing the wear on a computer’s memory. Over time, many heavily used cells within computers become damaged, and the memory must be replaced. Elizabeth’s system reduces the average number of times cells were accessed, compared to other options.
Rory Hu, 12, San Jose, Calif., demonstrated excellence in science, technology, engineering or math, along with the leadership and technical skills necessary in the 21st Century STEM workforce and built a better community for tomorrow. Rory’s research on honeybees suggests that feeding bees tea polyphenols (茶多酚) and caffeine could boost their ability to learn and remember.
Mina Fedor, 14, Berkeley, Calif., used electroencephalography (脑电图学), or EEG, to measure a certain type of brain activity as people did active and passive learning tasks. Mina’s research, which found that the brain doesn’t substantially differentiate between the two different kinds of learning, could impact the way educators teach.
Jeanelle Dao, 13, San Jose, Calif., created a promising solution to a real-world problem. She invented a foot-controlled welcome mat that wirelessly automatically unlocks a door when the user puts his/her feet on the correct code. The device could help people with arthritis (关节炎) and other hand problems become more self-sufficient.
