On Aug 7, Xu Shixiao and her partner, Sun Mengya, won gold in the first women's canoe (划艇) double 500 m event at the Tokyo Games. It was also the first Olympic gold medal for China in the event. 

Yet Xu's journey to the Olympics was bumpy-she faced lots of difficulties. 

In 2013, the news that women's canoeing was still not an Olympic event dealt her a heavy blow. 

At that time, Xu's coach suggested her either changing to another sport or retiring (退役) . 

It was impossible for her to change the sport at age 21. Xu gave up her career and found her first job as a saleswoman. The next year, she was promoted (晋升) as a human resources manager. 

When Xu went to work as usual in a company in Nanchang, Jiangxi province, five years ago, she was surprised to get a call from her former coach, asking about her willingness to return to canoeing and compete in the Tokyo Olympic Games. Xu quickly made her decision. 

"I quit my job, told my family about it and went back to training three days later. There was not much time left for me to prepare for the Olympics, "Xu recalls." I never thought that one day I could go back to the sport. Now that I have started again, I will do my best."

To catch the opportunity to go back to canoeing on the international level, Xu started her training —"as cruel as hell". She began her daily exercises early morning and ended at 10: 30 p. m. Every day, she would set several detailed goals for her training. "Only when I reached all my daily goals, I would go ashore," Xu says.

The more than two months of grueling (艰辛的) training finally paid off. Xu won two gold medals at the 13th National Games in two women's canoe events, which meant she would be part of the national team to compete in the Tokyo Olympics. 

Here are some amazing national forests in the United States that are perfect places to step outside and enjoy nature. 

White Mountain National Forest

It has an area of 148, 000 acres. This forest is known especially for its vast water resources, including 12, 000 acres of wetlands, 67 lakes, and so on. The forest houses almost the whole Mount Washington, the highest peak (山峰) in the northeastern United States, and is home to almost 200 kinds of birds. 

Superior National Forest

Established (设立) in 1909, it is famous for its forest ecosystem and its clean lakes (more than 695 square miles of the forest are surface water) . With over 3 million acres in total, there are some pretty important animals who call this forest home, including black bears and gray wolves. 

White River National Forest

White River National Forest in northwest Colorado is the most visited national forest in the country. Established in 1891, the biggest threats (威胁) to this forest are wildfires and insects. In the 1940s, a widespread outbreak of beetles killed 99% of the trees in an area of over 1, 000 square miles. 

Inyo National Forest

Inyo National Forest is known as a best place for camping, hiking, fishing and skiing with 2 million acres near the borders of California and Nevada. Another impressive feature of this forest is its Ancient Bristlecone Pine Forest, home to the oldest living trees in the world, some of which are almost 5, 000 years old. 

Early in my teaching career, I heard countless excuses— most of them fabricated (编造的), many of them amusing for why students didn't have their homework. And, yes, "the dog ate it" was one of them. As time passed and I grew less easily cheated, I grew tired of hearing "I don't have my homework because…"

And so I quit accepting any excuse other than a verifiable (能证实的) death in the family.

When I moved to an inner city middle school. I took my no-nonsense attitude with me. "No excuses, no extensions!" I warned my eighth graders on the first day of school. I collected homework at the beginning of each class. When a student didn't have it, I never asked why. Instead, I sighed loudly, shook my head in dramatic dislike and— with the student looking on-recorded a zero in the grade book. I soon gained the reputation I thought I wanted.

Then, one afternoon, shortly after the dismissal bell rang, Anthony approached me. "Could I talk to you a minute?" he asked shyly, not taking his eyes off the floor. "I know you said it doesn't matter why we don't have our lessons done. but I don't want you to think I'm a slacker (偷懒的人) because I come to school without mine so often."

Anthony looked on at me for the first time, and I could see that his lower lip was quivering (颤抖的). "It's just that… well, my dad moved out, and my mom waits tables at night, so I have to take care of my little brothers. Sometimes they cry a lot, and it makes it hard to concentrate."

I put my hand on Anthony's thin shoulder. "Why are you just now telling me...?" I stopped in mid-sentence. I knew why. So I changed the question. "Would it help if you stayed here in my classroom after school and worked on it before you go home?"

Dear Helen,

Yours,

Li Hua

78-year-old Nora Langdon spends four or five days a week at the Royal Oak Gym, near her home in Michigan. She 1  weightlifting competitions for three hours at a time. She has become a(n) 2  to people of all ages.

At the age of 65, Langdon determined to live a 3 life. In 2007, she weighed over 210 pounds and often 4 to catch her breath while going up the stairs. She knew it was time for a 5 . "On the first day I started going to the gym, I went home and told myself that I'm never going back again because it was too much for me," Langdon told Good Morning America. "Then I heard a voice 6 , ‘Go back.' So, I went back and here I am today."

After 7 the gym and watching her trainer prepare for a weightlifting match, she decided to try it herself. She began with an easy thing — using a broom as a barbell (杠铃) before 8 changing it to a real barbell. It wasn't long before she discovered weightlifting was her passion.

Although Langdon has 9  twenty of her weightlifting competitions and set state, national and world records, she shows no sign of 10 . Her next goal is to lift over a thousand pounds, according to her trainer, Art Little.

"She's really 11 to the gym, to me and to the whole weightlifting field," Little said. "It's a 12 to see what she's doing at that age."

She wants others to know that with motivation and strong 13 , anyone of her age can get into 14 . "You can live actively at an old age," she said. "Your body was made to 15 and you have to keep it moving in order to stay healthy."

How to Turn Your Dreams into a Reality

Do you have dreams, visions or plans about things you'd love to have or achieve? Of course you do! We all do. Unfortunately, dreaming is the easy part. The good news is that there are proven techniques that can get you from where you are to where you want to be. Follow this process to bring your dreams to fruition (实现):

Turn your dream into a goal.

When you have a goal, you have a true target. For a greater chance of success, your plan should have a deadline and it must be measurable. Give yourself the gift of setting a deadline and things will start to happen. Make your goal as desirable as possible without being unrealistic. If you feel that your goal is unreasonable, it's much more difficult to encourage yourself to actually pursue it.

Prioritize (优先化) your goal daily.

You give instructions to your brain thousands of times a day. Let your mind know that your goal is something more important than "I feel like eating a ham sandwich" or "I need to stop at the grocery store on the way home".

Difficult goals can rarely be achieved alone; you're likely to need some help and guidance. Look at the list you made and see what you already have in your life that could help you on your path.

Track your progress.

Measure your progress each day. Use old fashioned paper and pencil or take advantage of the latest smartphone app. You can only adjust your approach if you know how you're doing. Consider making a chart if that's applicable to your goal.

A. Read and write your goal each day.

B. Make a list of negative associations.

C. Classify (将……分类) your available resources.

D. Tracking is critical to making continued progress.

E. Turning those dreams into a reality is the challenge.

F. It has been said that dreams are goals without a deadline.

G. So make a list of all the negative stuff that slip into your mind.

The Food and Drug Administration (FDA) has to recall (召回) hundreds of foods every year. Like cookie snack packs with pieces of blue plastic hiding inside, dressing and sauce containing salmonella (沙门氏菌) or various jams containing with lead (铅).

It can take a few months before a recall is issued. But now researchers have come up with a method that might fast-track that process, leading to early detection and, ultimately, faster recalls. The AI system relies on the fact that people increasingly buy foods and spices (调味料) online. And people tend to write review s of products they buy online, which are like bread crumbs (面包屑) to food-safety officials sniffing (嗅) out dangerous products.

The researchers linked FDA food recalls from 2012 to 2014 to Amazon reviews of those same products. They then trained machine-learning algorithms (算法) to distinguish between reviews for recalled items and reviews for items that had not been flagged. And the trained algorithms were able to predict FDA recalls three quarters of the time. They also identified another 20,000 reviews for possibly unsafe foods, most of which had never been recalled. The results are published in Journal of the American Medical Informatics Association.

The World Health Organization estimates that 600 million people worldwide get sick annually from polluted food, and more than 400,000 people die from it. "So having tools that enable us to detect this a lot faster and hopefully investigate and do recalls faster will be useful not just in the U. S. but in other countries around the world as well." Study author Elaine Nsoesie of Boston University. She did add one warning: even recalled products can still get five-star reviews. So stars alone don't tell the whole sickening story. The proof, unfortunately, may still be in the pudding.

Contrary to popular opinion, the scientific pursuit for knowledge is not a predictable and well-defined process. To make new discoveries, researchers need the freedom to be creative, fail, and learn by chance. There is the romantic idea of the scientist who has an Eureka moment (顿悟时刻) and suddenly arrives at new insights. Another impression is that research only involves formal steps. Neither of those ideas is correct.

"Science and art are two different ways to make something understandable or imaginable," says Biochemistry Professor Dolf Weijers. "From the outside, the research process looks very formal and the artistic process looks somewhat messy. But the scientific process can also unfold (展开) in an unpredictable way. Creative and associative thinking is very important for scientists to gain insight and make connections."

There is an intersection (交叉点) between science and art. This is why Wageningen scientists look to artists for inspiration and exchange ideas about how to amplify creative freedom. Weijers and his colleague Joris Sprakel, together with other scientists and artists, have designed a plan to learn from each other and to exchange ideas. One example is the recent and special project in which they measured the forces that act on plant cells. A molecular (分子) sensor was used to visualise the different forces. They revealed the results in colourful images, each representing a different force.

What science and art also have in common is that they are topics of discussion in society. There are people who say that they do not value art and people who mistrust science. "It often creates the wrong impression because only the results of scientific studies are presented, and people do not have any insight into the artistic process leading to discovery. As a scientist, you are criticised if you say that something is different a few years later. Then you are viewed as unreliable. But what is often poorly understood is that there are no final results in science," says Weijers.

Born in Potsdam (in the Kingdom of Prussia) in 1821, Helmholtz was one of the 19th century's most knowledgeable scientists, whose name turns up in the histories of multiple scientific fields and specialties. As a youngster, he had an interest in physics, but that seemed a financially unwise career choice. He went to medical school and studied physiology (生理学) instead, because he was drawn to others who promoted the point that physiology should be based on the principles of chemistry and physics, not the "vital forces" that had been popularly emphasized previously.

After earning his medical degree, Helmholtz served as an army surgeon before becoming professor of physiology at the University of Königsberg. During that time, he composed a groundbreaking paper on the conservation of energy, which made him a good reputation (名声) in science community. His main argument is that all science can be reduced to mechanics. It is emphasized that Newtonian mechanics and Lagrangian mechanics are mathematically equivalent (相等的), so a force can be measured by the Laplace method in terms of the energy transferred by the force or the work done by the force. All of this energy is conserved. While at Königsberg, he studied the nervous system, optics (光学) and acoustics (声学), especially with regard to the physiology of the senses. Then he moved on to the University of Bonn as professor of anatomy (解剖学) and physiology.

After some time at the University of Heidelberg, where he became interested in philosophy, in 1871 he was awarded the physics chair at the University of Berlin. At last he could focus on physics, emphasizing the importance of the principle of least action for explaining physical phenomena. He also explored the branches of Maxwell's new theory. By this time, he was recognized as one of Germany's premier scientists, until his death in 1894.

A Reminder Bracelet (手链)

Description

The "Within Good" product line was created as a way to encourage positive thoughts and good deeds.

In one simple design concept, it is a wearable reminder to people of all backgrounds that "Within Good, There Is God"—a pure message that no matter what you are going through, you can always do good, and the spirit of love, known as God, is always within us and in the world.

Within Good is not intended to be a religious bracelet. In fact, one of the reasons why the "God" reference appears on the inside of the bracelet is because it is personal to the wearer. The company co-founders say their concept was to go back to the basics of doing good for yourself and others: "At the end of the day, God symbolizes peace, love, connectedness, purpose, and any other word that makes you feel GOOD."

Over many months, the logo (标识) turned into a symbol represented by the double "o" in Good and interlocking with the G and D. "Within Good" is printed on the top of the bracelet and on the back is printed, "There Is God". The rope symbolizes strength, and a strong connection between Good and God (always inside us).

Why This Is a Good Gift:

Looks Great: Casual yet classy styling, in a unisex (中性化的) design.

Gift Packaging: Each bracelet arrives inside its own little drawstring bag, ready to give away without wrapping (包装).

Discount: $29.99  $26
