Harry Linehan, 13, and his brother Tom, 15, are both members of the Sorrento Surf Life Saving Club. Last Sunday morning, they were training at the beach when a couple 1  and alerted them to a man offshore who was in 2 .

There were no lifeguards 3 , so Tom made a beeline to the man on his racing paddleboard (冲浪板) and shouted to Harry for 4 . And, as any younger brother would, Harry 5 . When the boys got out to the man, they noticed he was 6 to keep his head above water. With great efforts, the boys 7 to get the man on a racing board and 8 pulled him and the heavy kayak (独木舟) back to shore. 9 , the man was OK and did not need further medical assistance. "He 10 us, but he was definitely in a state of 11 ," said Tom.

A representative from Surf Life Saving Club arrived shortly afterwards and was 12 the boys had been able to put their training into 13 . Their father Nathan said his sons had been 14 for situations exactly like this. "The purpose of the organisation (SLS) is to teach people 15 so they can use them when needed. The 16 just put them into action," he said.

Harry has a surf rescue certificate and Tom 17 a bronze medal in a surfing competition only a week before the 18 . "If I didn't have the training I wouldn't have known what to do... you don't realize the skills you have until you 19 them," said Tom. "Anyone with the 20 training would have done the same thing."

How to stay healthy on holiday

Taking time to relax on holiday may be good for our health. . Here's how to stay healthy when you travel.

Plan before you go

Besides the stress of organizing your break in the first place, there's the added anxiety of remembering to buy and pack everything you need, as well as getting where you need to go on time. To avoid this, as soon as you've booked your holiday, list the travel documents you'll need. Check you have them and they're valid (有效的). Then start packing several weeks in advance, giving yourself time to buy some daily necessities. .

Try to forget the cares of everyday life. You can achieve this by ensuring you don't check emails or social media, or feel obligated to use it to record your best holiday moments. Ideally, turn off notices, limit your screen time and try to focus on the present moment. That will enable you to relax and make special memories.

Eat and drink well and mindfully

. Take time to really enjoy all the flavors. However, you should be aware that too many alcoholic drinks can cause "holiday heart", characterized by an irregular rhythm. What's worse, if you're holidaying in a hot climate, that can also result in dehydration (脱水).

Get active

Try a new activity. Consider walking and swimming or tennis. . Remember that being active not only helps you stay fit during the holiday, but also makes you feel fitter and more refreshed once you're back.

A. Ignore all the barriers in life

B. Get rid of the digital addiction

C. But there's a physical reason for this

D. However, too much relaxation also has opposite effects

E. Part of the fun of going away is experiencing the cuisine of other places

F. On departure day, leave more time than you need to get to an airport or port

G. If you're somewhere hot, it's best to work out in the early morning or evening

The concentric circles（同心圆状斑点）, also known as eyespots on butterfly, not only look like real eyes but may also appear to glare directly at predators（捕食者）from many directions, scientists have found. This visual illusion, called the "Mona Lisa effect", could scare would-be attackers and buy the insects enough time to escape.

Scientists suspect that eyespots, with dark "pupils（瞳孔）" in the center look like real eyes to predators. Hannah Rowland, an ecologist at the Max Planck Institute wanted to see if the direction of this fake gaze contributed to the effect.

First, Rowland and her co-author trained chicks to attack a worm hidden behind a paper printout of two eyespots at the end of a path. When the eyespots' pupils were specifically pointed in the chicks' direction, the birds repeatedly ran toward the paper and then backed away, and they waited a few minutes before attacking. But when the pupils instead appeared to look away from the direction of the chicks' approach, the birds attacked in seconds. Centrally located pupils, though not as effective as ones that stared directly at the chicks, resulted in longer delays than pupils that looked the other way.

"This suggests that they really are paying attention to the direction of the pupils in the eyespots and are perceiving them as eyelike stimulation. The concentric eyespots found most often in the insect world may seem to the chicks like a pair of eyes that follow them regardless of approach angle," says Rowland.

National University of Singapore evolutionary biologist Antonia Monteiro, who was not involved in the research, says the study is a "cool" demonstration of an evolutionary theory for eyespots. "These butterflies can be encountered from all angles, so having the pupil centrally located ends up being pretty good," Monteiro says. Still, she says, the eyespots used in the study were several millimeters larger than even the largest commonly found in nature, raising the possibility that the chicks may have been extra frightened by the size of the paper eyes.

Right now, over 3,300 high school and community teams are assembling（聚集）around the world in anticipation of the upcoming season of the FIRST (For Inspiration and Recognition of Science and Technology) Robotics Competition, which will begin an intense eight weeks of designing, building, and programming new devices in January.

In two-and-half minute matches, robots compete in groups of 3-vs-3 on a volleyball-sized playing area. Each match starts with fifteen seconds of autonomous action, when robots are programmed to score points on their own. Then, behind a plexi shield（有机防护罩）, the humans step up to control their devices, and it's on-speed, power, grace, defense, teamwork, showboating and the occasional collision with bits of plastic and metal flying around.

Robotics competitions are nothing new, but over the last few years, the FIRST Robotics Competition has developed from a fascinating after-school activity to having a real impact on the tech and engineering world. Demand for workers in fields like automation and connectivity, against recent declines in engineering college graduates, makes a recover, showing multiple years of hands-on high school robotics increasingly desirable in corporate America. "We like to see evidence of project-based learning, working in teams, hands-on experience and that sense of discovery," says Jennifer Cluett, head of admissions at Worcester Polytechnic Institute.

A who's-who list of FIRST sponsors-including Coca Cola, Amazon, Apple and Disney -shows how eager big businesses are to prime the pipeline. "Traditionally we would look very heavily at a college GPA（平均分）. But increasingly companies are looking for more well-rounded employees," says Jody Howard, vice president of innovation and emerging technology at Caterpillar Inc. "What's so interesting about FIRST is that, while they may be coming out with robotic or programming skills, it's really the teaming and problem-solving that make them stand out."

For working parents with busy schedule, mornings are hell: preparing meals, ironing clothes, feeding the children, packing lunches, ensuring everyone has what they need for the day... But I'm pleased to say my perspective on mornings is sunnier than most parents, though being woken at 6 am by kids was hardly a welcome addition to the night owl like me.

The different views first arise partly from opinions on television. I don't see the harm in letting my kids watch a bit of television before school, so long as they still make time to get dressed, eat breakfast and brush their teeth. This balance took years to achieve: a routine steadily drilled into them via daily practice -pause the TV program with complaints and screams-to fulfil each everyday activity; but, now they've observed that the quicker they perform their essential tasks, the quicker their entertainment will restart.

With morning necessities completed with speed and proficiency, then comes the 15-minute walk to school. In our family, it's me and the dog who do the school run, and it's actually one of my favourite times of the day. This quarter of an hour provides me privileged access to my kids when they're at their freshest; rather than at the end of the day, when they're tired, hungry and annoyed. They ask stimulating questions, "How is ice cream made?" "How long would it take to drive to Mars?", but they usually can't hear my answers over the drowning noise of the traffic.

Best of all, there's the walk back: just me and the dog, enjoying the silence. A moment to recharge and reset, ahead of a day's work, and I am grateful for the joy of my family, and perhaps more grateful still that someone has just taken them off my hands for the day. Oh, what a beautiful morning!

Saving the Daisies

Taylor aged 14 opened her sleepy eyes and looked out the window below. "NO!" she cried, now fully awake. Buttermilk the cow was in Mama's daisy（雏菊） garden. 

"I must have forgotten to close the gate last night, " Taylor thought as she pulled a sweatshirt over her head. Mama was planning to sell the daisies at the fair next week. But Buttermilk was eating the flowers. Taylor hurried outside and grabbed a rope. 

"Why can't you stay in the field?" she called to Buttermilk as she headed across the yard to the daisy garden. Buttermilk stood biting the tender flowers. 

"When I grow up, I'll be an artist and paint pictures all day, " Taylor thought. "I'll not own a cow. Too much trouble. " Taylor was fond of painting since the day she had memory. She would like to help with family but she loved seeing birds and flowers alive under her brush more. 

Just as Taylor was about to throw the rope onto Buttermilk's collar, the family dog barked. Buttermilk couldn't stand it and took off, tearing through the daisies. It finally ran through the open gate and into the field outside. "Thank goodness!" Taylor said as she closed the gate and secured the lock. But as she turned to look at the flower garden, most of the daisies were either eaten or left in pieces. 

Mama and Dad came out of the house. "What's going on?" Mama asked. She looked sadly at her garden. "I forgot to close the gate, "Taylor said. "I'm so sorry. ""I know you are. "Mama sighed and gave Taylor a hug. 

Taylor's heart was heavy as she went back into the house. Mama had prepared much for the fair but now half of her efforts were in vain. Taylor decided to think of a way to make it up to her mother. The problem tasked Taylor's mind. Could she plant other flowers in a week? Not enough time. Could she make use of the daisies in pieces? Not enough magic. Taylor found no way out.

Students' Time Spent on Physical Exercise Weekly

Nowadays, many students are aware of the significance of physical exercise, although the time they spend on it varies. 

Xi'an, capital city of Shaanxi, served as the capital of 13 dynasties in Chinese history, which in total （last）about 1, 100 years. Consequently, the ancient history of Shaanxi is to some degree the ancient history of China. Shaanxi History Museum considers  a duty to be a showcase of Chinese ancient civilization. 

People call Shaanxi History Museum "Bright Pearl in Ancient Capital and Precious Treasure of China", for it is an art palace （full） showing Shaanxi history and culture as well as Chinese ancient civilization. Its architectural buildings and exhibits have made it famous as a first-class museum in China  it was opened to the public in 1991. It covers  total area of 65, 000 square meters. 

The basic halls in the museum are divided into three exhibition halls  

2, 000 cultural remains to display the history of ancient times in chronological （编年的） order. The first exhibition hall （locate）on the ground floor while the other two are on the second floor. 

While （design）the buildings in Shaanxi History Museum, the great designer used （tradition） palace construction of Tang Dynasty for reference. Adopting symmetry axis （轴对称） layout with main and supporting buildings in order, the complex （architecture）show the unique presence of Tang Dynasty. 

Harry Burleigh headed into the woods for a camping trip with his fishing equipment. A few days later, his wife Stacy grew 1  when he didn't come home as planned. 

Stacy called the 2  to report her husband's missing. Search and rescue teams 3  began their work and went on for days, but there was no 4  of Harry anywhere. Everyone was worried -the temperatures were quite low some nights, and it had even snowed. 

On May 15, the rescuers finally caught a break when they 5  a shelter and his fishing equipment. They 6  support from over 16 rescue organizations, and they explored every possible 7  but with no luck. Therefore, the rescuers 8  him a lighter and a note telling him to make a 9  and they would be back. Two days later, a team found another 10 , but this time, Harry was nearby and heard his name called! It turned out he was 11  along the path with minor pain. 

12 , the crew radioed for a helicopter to take him to the hospital for a complete evaluation after spending 17 long days out. 

"This was the 13  we all have been looking for in this case, " a rescuer said. "It is our 14  search and rescue teams and the partnerships we have with other teams that helped 15  Mr. Burleigh and his family. "

For the past two months, Mandy Chen, a second-year student at Beijing University of Technology, has been posting photos of herself to Taobao, posing with a reusable cup, climbing stairs and switching off lights.  Taobao's Al algorithm （算法） calculates that Chen's use of a reusable cup reduced 15. 7 grams of carbon emissions （排放）, while her choice to take the stairs instead of the lift resulted in a reduction of 19.5 grams. 

After seven days of posting her photos, Chen exchanged the points for a dozen of biodegradable rubbish bags from Taobao. Everyone can get an endless supply of free trash bags if they keep going, according to Chen. 

Chen uses Carbon88, a platform launched last August by Alibaba Group Holding, to help the more than 800 million users on Taobao adopt a sustainable lifestyle. The platform rewards users for over 70 low-carbon behaviours.  It also recommends products that it considers environmentally sustainable, and gives users points for buying them. 

 "I didn't know that my actions could produce such carbon reduction, " Chen said, "Now I feel good for what I'm doing to make this world a tiny bit better. We as a part of society can call for more systemic changes. "

A. It aims to encourage them to reduce their carbon footprint. 

B. And her efforts to save electricity prevented 65.50 grams. 

C. It's a valuable addition to current carbon-reduction policies. 

D. Carbon88 has helped increase Chen's environmental awareness. 

E. Within minutes, she receives a dozen points from the app as a reward. 

F. They range from taking public transport to shopping of second-hand items. 

G. She is now saving points for something better, like snacks and water bottles. 

You see a shopper trip over in a busy street. Someone else can help. That's what you tell yourself. This is the bystander effect（旁观者效应） in action—the dilution（淡化） of responsibility in the presence of others — and it has been demonstrated in many past studies.

But life is complicated and psychologists have seen exceptional situations. Recently two experiments were conducted by Marco van Bommel and his team using an online chat room for people with extreme emotional problems. Eighty-six students were logged into the forum （论坛） and shown five messages from troubled users. They were told to write a reply if they wanted, but it was entirely up to the students themselves. 

Basically, participants could see their names on the screen alongside others' names. A counter also told them if the forum was quiet with just one other person logged in, or busy with 30 others online. This arrangement reproduced the classic Bystander Effect—participants were less likely to post replies with more people logged in. However, when the researchers cued （提示） self-awareness by highlighting participants' names in red on the screen, they posted more replies on a busy forum.

A second study was built on these findings, but this time self-awareness was raised by the presence, or not, of a computer web-camera. Over 100 participants took part. Then researchers found that the Bystander Effect was reproduced when web-cameras were absent —on busy forums participants posted fewer replies to needy users. On the contrary, those cued to be self-aware by the web-camera actually wrote more replies.

Nearly any online community can benefit from the research. The ability to turn hesitant bystanders into eager helpers is a recipe for engagement and collective benefit. As in the research, simple design cues could be integrated to help online users remember they are visible to the community. 

When delivering medications to patients, one of the most effective methods is direct injection （注射） into the bloodstream using a needle. But this can be an uncomfortable experience, especially for kids or adults with a fear of needles. While patients do have the option to take oral pills instead, drugs containing large molecules（分子） are not absorbed effectively this way. 

Now, inspired by octopus suckers（章鱼吸盘）, researchers from China and Switzerland have designed a needle-free alternative: a tiny, drug-filled, cup-like patch （贴片） that sticks to the inside of the cheeks. The device is easily accessible, and it can be removed at any time and the drug gets absorbed through the lining of the inner cheek, the team reports in a paper in Science Translational Medicine. 

To test the design, the team 3D printed the suckers. They loaded each with the drug and stuck them inside the cheeks of three beagles, a kind of dog which has a similar inner cheek lining to humans. For comparison, they also delivered the drug to beagles via a pill. After three hours, the team found that drug blood concentrations in dogs with the patch were more than 150 times higher than in the dogs that took a tablet. They also found patches worked effectively for drugs with large molecules. 

40 healthy human volunteers self-applied water-filled patches to see how well they would stay on while talking and moving their mouths. After 30 minutes, only five of the 40 patches had fallen off, which was because of improper placement. Most volunteers said they would prefer a patch over injections for daily applications. 

Still, the team only tested the patch for a short time so they would need to find out what would happen if it was used repeatedly. They'd also need to determine which drugs would work with the technology: the target is large molecules, such as those used to treat obesity or osteoporosis, but they can't be too large to fit in the cup. 

3M and Discovery Education announced Sean Jiang from Gilman School as one of the top ten finalists from across the nation for the 2023 3M Young Scientist Challenge. It's a competition that encourages students to identify an everyday problem and submit a video showing the science behind the solution he or she came up with. 

14-year-old Jiang decided to help those who can't see. Blind people had a hard time navigating（导航） objects that are medium to far range. So Jiang wanted to design something to give them a heads-up on obstacles（障碍） that may be incoming. 

Jiang's inspiration came from the powers of the hearing system. "I learned in school that bats and whales are able to use echolocation （回声定位） to help them navigate and just use their sense of hearing and I also saw on YouTube some very skilled blind people that use echolocation to help them walk, "said Jiang. 

Jiang started with a virtual reality setting and then made it a reality. His creation uses a depth camera that can detect how close objects are, thus giving enough time to dodge the obstacles. When a blind is walking with the device, the sensor of the depth camera gathers the information regarding the obstacles' position and distance. Then the AI system in it will turn the distance data into musical sound guidance. This could significantly increase the walking speed of a blind person as well as decrease the number of obstacles they hit. 

Some other similar programs were alright at finding objects that were in close range, but Jiang still wanted the blind to experience the world even fuller so they were able to see stuff that was much further away than their circle of reach. 

In October, the top ten finalists will compete in person in Minneapolis for the title of "America's Top Young Scientist" and a $25, 000 prize.

Being the youngest in my family has had its advantages, of course. But being the youngest also came with its fair share of troubles. I was often told what I couldn't do and why. I knew that my family loved me. They always tried to protect me, help me and take care of me, but I couldn't wait to show them I could do things by myself.

It was a hot day in Florida. The school year had just ended and it was time for summer vacation. We had just gotten a little black dog who we named One-Eyed.

Everybody wanted to do something for the dog: feed him, teach him tricks and take long walks with him. Everybody was so happy to have this little active, playful new addition to our family. I was so desperate to pet One-Eyed myself, too. Every time I asked my brother or my sister if I could do that, they would shout, "No!" or tell me that I had germs (细菌). Once, they even convinced me that I had so many germs and that if I touched One-Eyed he would die! I really believed them and was scared that something terrible would happen to the dog. Once I even confessed to my mom that I touched the dog when no one noticed. At first, my mom seemed very confused about what I was telling her, but then she realized that they were playing a joke on me to keep me away from the dog. My mom scolded my brother and sister, "You better stop teasing your little brother!" Little brother! That's exactly what I was. That really got my blood boiling. The frustration built up inside me as I watched them enjoy their time with One-Eyed, excluding me from the joyous moments. I knew I was capable of taking care of myself and forming my own connection with our new furry friend. Determination filled my heart, fueling a newfound sense of independence.

I took one look at the dog and decided, I was going to prove to everyone that I could pet and play with One-Eyed.

Seeing this, my brother and sister couldn't believe their eyes.

Dear Chris,

Yours sincerely,

With a history of more than 2,000 years, the Silk Route dates back to the Han dynasty. Through this route, the Chinese highly qualified silk made its fame to the western countries. The merchants in different regions (seek) the opportunity of trading Chinese silk where they indeed made their fortune along this route. That route functioned the life blood of international trade at that time. Meanwhile, the Chinese civilization (introduce) to the Western countries and vice versa. The Silk Route was considered as a new chapter (record) the friendship between the European and Asian peoples.

Throughout all these years, many great figures have made significant contributions to the development of the Silk Route. Today, the Silk Route has a (poet) name called One Belt One Road, (aim) to help those connected regions in culture and economy exchange with a more advanced road. The main cities alongside it are becoming (large) and more important in helping trade and culture exchange. Many countries have gained great (benefit) along the trading process. All in all, the ancient Silk Road is more like  historical textbook for everyone to read and to know about  happened during that ancient time. It has been playing a significant role in the development of the civilizations of China.

One of the primary goals of cognitive behavioral therapy (疗法) is finding effective ways to channel your anxiety into productive action. The best possible one is under the care of an experienced mental health care provider. Still, if you are hoping to stop being paralyzed (麻痹) by anxiety and use this energy to fuel and improve your life, you can. 

Set a goal. Goal-setting is one way to use your anxiety as fuel. Take notice of your anxious thoughts and worries. What are you most concerned about?  Instead of shaking in your boots, get to work developing a plan that allows you to overcome these fears.

Challenge yourself regularly to build resilience. Think of your resilience to anxiety as a muscle.  Rather than avoiding those situations that cause anxiety, gradually expose yourself to them more often. When you do this, you will find that, over time, they lose their power. For instance, if you hate public speaking, you might benefit from signing up for a local Toastmasters club. Doing so will allow you to practice speaking in front of a group more often, which will reduce your anxiety.

 Anxiety can feel like a live wire in your body. You can't sit still or focus. Exercise is a great activity to make use of this spare energy. Exercise offers a host of benefits like fighting off illness and helping you manage weight. One of the benefits most helpful to you, however, is its ability to neutralize anxiety and improve your mood.

Perform reality testing. You don't have to become a slave to your anxious thoughts, giving them permission to get you all worked up.  Reality testing involves assessing a situation for errors in thinking. To assess the reality of this situation, you want to ask what evidence is there that says this is true. Did your friends actually call you lame? Are they avoiding you?
 

After years of severe drought combined with climate change, the water level in Lake Powell, the second largest reservoir on the Colorado River, has dropped to just 24% of capacity. It is continuing to decline to levels not seen since the reservoir was first filled in the 1960s.

In an effort to improve the shrinking reservoir, the federal government announced that it will hold back a large quantity of water this year to reduce risks of the lake falling below a point at which Glen Canyon Dam would no longer generate electricity.

"Today's decision reflects the truly unexpected challenges facing the Colorado River Basin and will provide operational certainty for communities and businesses that rely on the Colorado River," Tanya Trujillo, the federal Interior Department's assistant secretary for water and science, said in a statement announcing the measures.

It is the first time the U. S. Bureau of Reclamation has called its authority to change its operations in this way at Glen Canyon Dam on the Arizona-Utah border. The agency said the plan is intended to protect infrastructure at the dam and its ability to generate hydropower. It will ensure that water supplies continue to be available for the nearby city of Page, Arizona, and the Navajo Nation.

The plan is supposed to reduce the risks of Lake Powell falling to extremely low levels. The measures will include releasing about 500,000 acre-feet of water from Flaming Gorge Reservoir, which is located upstream, and leaving an additional 480,000 acre-feet in Lake Powell by reducing the volume of water released from Glen Canyon Dam.

"What's needed now, urgently, is for federal and state water managers to work in partnership with other related parties, to take the steps necessary to build confidence in the long-lasting management of the Colorado River," Pitt said. "This will require intensive and dedicated resources to develop and implement plans that put water demands into balance with supplies."
