Tired of telling students to ask questions and to think about what they were doing, Damien Hynes, a high school teacher, decided to do an experiment to test what he had long been thinking. He wrote some well-organized nonsense (谬论) on the blackboard. The students simply copied it but very few asked any questions. This shows that students are willing to believe anything given by teachers. The story is repeated in support of the Project for Enhancing Effective Learning (PEEL). 

PEEL was carried out by some teachers and researchers in Melbourne who had discovered that normal teaching methods seldom achieve their intended goals: what the teachers think they are teaching is one thing and what the students actually learn is something else. Students' lack of an over-all view of learning goals and their concentration on test scores make them see each lesson as a separate activity.

Researchers realized that many students do not come into class empty-headed but have their own explanations of how the world works. Their own ideas can remain important to them even when they conflict with scientific explanations that are learned later. In fact, such ideas are hardly affected by traditional teaching. Students accept the teacher's scientific explanation, but do not drop their own. In a class test, they copy the teacher's idea, but in real life they use their own.

Clearly what was needed was to make students aware of their learning process, and this is what the PEEL teachers set out to deal with. In the class being taught by PEEL methods, there are some meaningful changes. Students are given much more time to express their views, and teachers don't make immediate judgment. The students are allowed to guide what is done in class and their own ideas are always respected. This draws their attention to the actual learning process, and they become responsible for their own progress.

The PEEL researchers believed that their experiment would be proved valuable if the experiences of children and teachers in different classes using PEEL methods were similar. So far, all teachers and students who have worked with PEEL methods agree that their approach to teaching and learning has really changed. The students are far more ready to question what is presented to them, while the teachers have realized that the traditional methods are not good enough. 

Once, I was invited to see a performance by my friends. Little did I know that I was about to see something I would never forget. 

After the host made a brief introduction, the young musician, Mr. Patrick Henry Hughes, was rolled onto the stage in his wheelchair and began to play the piano. His fingers danced across the keys as he made beautiful music. He then began to sing as he played, and it was even more beautiful. For some reason, however, I knew that I was seeing something special. About ten minutes into Patrick's performance, someone came on the stage and said, "I'd like to share a seven-minute video. " Then the lights went dim.

Patrick Henry Hughes was born with no eyes and the inability to fully extend his arms and legs, which left him disabled for life. However, as a child, he was fitted with artificial eyes (义眼) and placed in a wheelchair. Before his first birthday, he discovered the piano. His mom said, "I could hit any note on the piano, and within one or two tries, he'd get it. " By his second birthday, he could play simple songs as requested. His father was excited. "We might not play baseball, but we can play music together. "

Later, Patrick became a junior at the University of Louisville. His father attended classes with him and he made nearly all A's. He was also a part of the marching band. He and his father did it together. They attended all the band practices and performances.

But even more than his unbelievable musical talent, it was Patrick's "attitude of gratitude" that touched my soul. On stage, between songs, he talked to the audience about his life and about how blessed he was. He said, "life made me blind and unable to walk. BIG DEAL! It gave me the ability… the musical gift I have… the great opportunity to meet new people. "

When his performance was over, Patrick and his father were on the stage together. The crowd rose to their feet and cheered for over five minutes. 

If you don't know what to watch in the coming holiday, here are the top movie search engines on the web. Some require little or no input before they give you titles, while others want to find out exactly what your interests are.

Rotten Tomatoes

Instead of telling Rotten Tomatoes which films you like, you can tell it what kind of films you enjoy, which actors you want to see, and other aspects to help it find the best movie for you. The quality of Rotten Tomatoes recommendations is changeable but it's also a nice way to find the right film for any mood.

IMDb

IMDb automatically recommends similar films to the movie you search for instead of asking you to input ratings (评分) or to tell it what movies you like. At the bottom of the page, a "Recommendations" section will show you a variety of other films being displayed, based on information gathered from its database, which examines films to find similarities and differences.

Jinni

Whether you want to search for films based on your mood, time available, or reviews, the site has it all. But Jinni's most amazing feature is its semantic search. You can enter words like "films that show Chris Farley yelling" and the site will return films that match your question. Go to use Jinni. You won't regret it!

Criticker

Instead of just allowing you to rate films, Criticker compares your ratings to those of other users and see how closely your tastes match those of other users. Once the service finds matches, you can view these users' lists and see which movies they like. Combining community and functionality, Criticker is a unique, yet worthwhile service to check out.

Single-use plastic bags are used at most a few times before they  (throw) away. It takes them hundreds of years  (break) down. Many of these bags end up in the ocean where larger ones can trap sea creatures, such as turtles and dolphins. Over time, the bags fall apart into countless tiny pieces, and fish can  (accidental) eat some of them. Now, lots of  (country) and regions are taking action to ban the sale of such bags to stop people using them.

Marlee (become) deaf when she was one and a half years old. Although she can't hear anything, she is positive towards life: "The only thing I can't do is hear. " Her parents sent her to a public school, Marlee got used to the life soon. (help) by the school, she became the first deaf actress to receive an Academy Award. "I work every day to help people understand. Deaf people not only deserve respect, they deserve to be heard," Marlee said.

Years ago, my grandmother was in a nursing home. She was a retired university professor, which brought her an ocean of 1  she had taught before. 

2  from my grandmother, almost no one came to see the old man next door. He was 3  most of the time. 

Once I greeted (打招呼) him, "How are you doing recently?" He gave me a(an) 4 , saying nothing. Thinking he was 5 of hearing. I raised my voice and asked again. He just shook his head slightly. After a long while, finding I was 6 there, he just said, "Fine. " Then he looked away. I had to shut up, feeling rather 7 .

Later, I learned that the old man had got quite a few companies from his family. Since he was not a good 8 , he annoyed many people and even made his family and friends pull away. And 9 , his companies all failed. 

So what is the most important 10 a person can have? Perhaps you think making money is the answer. No! But the ability to 11 your thoughts is. It's extremely important for a person to learn to put what he thinks into 12 . It makes a relationship 13 and a career flourish (繁荣). I'm afraid this is something many of us don't have. Just think: How many of us have ever 14 those who love us just because we are not good at speaking? So, more often than not, it is not what we think but how we speak that 15 how far we can go in life.

International Friendship Day is a day when friends show (appreciate) for one another. 

In 1919, International Friendship Day (found) by Hallmark. It was intended to be a day for people (celebrate) their friendship by sending each other cards. By 1940 the market (dry) up, and finally, it died out completely. In April 2011, the United Nations (official) recognized 30th July as International Friendship Day, although most countries still celebrate it the first Sunday of August!

On International Friendship Day, taking a trip together to celebrate is an excellent way to make the day all about each other. You can visit places you first met or go to wherever you promised each other to go. With so many people (live) such busy lives, however, not everyone can plan a big day out for each other. But that's what makes International Friendship Day such a (wonder) time. Best friends understand that life often gets in the way, so they won't be upset if there's no big celebration in their honor. Moreover, with rise of social media, we become more connected than ever before, so International Friendship Day just gives everyone the chance to get together.

After ten years in the same company, I found my job was no longer fun. However, I didn't have the confidence to apply for new jobs due to lack of experience. I felt 1 .

A friend suggested another path—2 . I had toyed with the idea of studying for a master's degree but 3 stood in my way. Yet I found a course at London College of Communication, 4 my job and enrolled(入学).

During the 18 months that followed, I began to flourish(茁壮成长). Not only had I found the courage to take my 5  forward in a new, exciting direction, but the self­doubt that had followed me around like a 6  began to disappear gradually. My classmates and I treated each other as 7  ：younger students 8  my experience and knowledge when it came to group work. I made new friends and joined committees.

When talking of a typical mineral mine, people will probably think it's underground. It's unlikely that the picture of plants and soft greenery would cross their minds. Now, new explorations into phytomining(植物采矿) may change that viewpoint. Instead of traditionally mining metals like nickel, iron or cobalt from rocks, phytomining uses plants as an alternative source for these minerals. Using plants to extract(提取) metals can have significant environmental benefits over rock mining.

Phytomining was first studied in 1983, but it hasn't yet been adopted by the metals industry. In 2004, Indonesian soil scientist Aiyen Tjoa from Tadulako University in Central Sulawesithe took her research to Sorowako, a small town in Indonesia with one of the largest nickel mining areas, to look into plants that continued to live after years of mining. She brought samples back to her lab and found that these super plants were more than just surviving—they were growing.

The plants were absorbing and storing nickel from the soil. Large quantities of metals killed most plants, but these, known as hyperaccumulators, were learning to adapt. If these plants were storing metals, that meant that science could find a way to extract the minerals for use and quite frankly, scientists easily did. When the shoots are harvested and burnt, the metals are separated from the plant material in the ashes. 

Tjoa returned to Sorowako and spent years searching for new hyperaccumulator species. After a plant is considered a possibility, there's a simple test paper that turns pink when placed against the leaf of a hyperaccumulator plant. Two local Indonesian plants, sarcotheca celebica and knema matanensis, were found but there are many others still to be validated.

Tjoa's research caught the attention of Satria Bijasksana, a professor of rock magnetism. Together, they designed an experiment to understand magnetic susceptibility(磁化率) when plants accumulate more nickel. Their research led to the discovery of two new species of hyperaccumulators. Besides, this research serves as the basis for the potential that plants can give to the mining industry, offering great advantages to our ecosystem and towards building a more sustainable(可持续的) future.

Thirteen Things Mentally Strong People Don't Do by Amy Morin

Do you spare no effort to get over your failures? Or concentrate on things out of your control? Getting over these obstacles can have a significant influence on your everyday life. Morin shares how her most successful therapy patients overcame these difficulties. 

Here are some tips to get your little ones to help you do housework naturally. 

Expose kids to housework as much as possible

When they are young, let them watch you cook, wash clothes or walk the dog, or let them help make a bed. . 

Especially during the early years, give children the opportunity to wander over and watch what's going on with the adults. . No lecturing or explanation is needed. This psychological integration(融入) into the family is really important for kids to learn to work together with others later in life.

A big motivating force for young children is being around their family, working on a common goal. This motivation is lost if we divide up housework so everyone is working alone. Therefore, if you're doing laundry, be sure everyone is folding everyone's clothes. If you have the children just fold their own clothes, the task becomes more about working independently.

Don't force it

Sometimes people think that to get children to do housework, the parents must be doing a really good job of controlling the kids. . The aim is not to control the kids, but rather to develop the children's own initiative(主动性).

Forcing the child actually has the opposite effect. It can generate resistance. 

. Asking a little kid "Could you help me with this？"often gets them on board more often than simply saying"You must do this".

A. Actually, the opposite is true

B. Always aim to work together

C. The goal is to control the parents

D. Change your mind about young children

E. Just like adults, kids don't like being bossed around

F. You'll be surprised by how much children learn by simply observing what you do

G. Basically, be sure they're around anything you want them to help you later in life

Tommy, a 26-year-old chimp(猩猩), lives in a small cage in a used truck sales lot in New York. Retired from movie work and whatever else once occupied him, he has no chimp friends to keep him company—just a TV. He is worlds away from the rainforest of Western Africa, where chimps spend most of their lives in trees, hunting, and socializing together. 

His owner hasn't broken any laws, but an animal rights group called the Nonhuman Rights Project (NhRP) is trying to change the view. The group says chimps have such a humanlike intelligence that they should be recognized as "legal persons"and be placed in an animal shelter and wander free.

You've probably heard the term "animal rights", but animals don't actually have rights in many countries. Animal-welfare laws punish people who mistreat animals, but that's not the same as chimps having a right to liberty or anything else.

NhRP's first step is to ask a judge to end people's unjust arrest on behalf of Tommy and other privately owned chimps. If the court decides to recognize chimps as legal persons, NhRP's next step will be arguing for what rights the chimps should be granted. "The right that we believe they should have most of all is the right to bodily liberty, "says Wise, a NhRP group member. "They should be able to choose how to live their lives. "

Tommy's owner, Pat Lavery, says he rescued Tommy from a careless owner about a decade ago and denies the chimp is mistreated or unhappy. "He likes being by himself, "he says.

"There's a danger in making a jump to say they're just like people, "says Richard Cupp, a professor who writes about animals and the law. "If we're really focused on chimps being very, very smart, then who knows if maybe someday we might. . . say, ‘Hey, here's a particular human being that's not very smart at all, maybe the chimps have higher status than this person. '"

Launched in Singapore last November, Hong Kong-based company Omnifoods has introduced a range of six plant-based sea foods to stand in for tuna, crab and whitefish. Similar to their pork substitutes, the new products are said to offer a safe and alternative source of protein while tackling environmental concerns like overfishing and worsening of the seas. 

Omnifoods' expansion comes at a time when the market for plant-based products is growing. According to Enterprise Singapore, local interest in sensible consumption doubled in 2021, and flexitarians—people who primarily eat a plant-based diet but occasionally consume meat or seafood—represent the fastest growth. The ocean is another reason cited as the need for plant-based seafood. The average person here consumed 22kg of seafood last year, surpassing the global average of 20kg. The World Wide Fund for Nature(WWF) also observed that three quarters of the seafood served in Singapore is unsustainable. Besides, fish farming involves the use of chemicals to prevent disease and parasites and these chemicals then accumulate in fish tissues, which becomes a serious threat to people's health.

Omnifoods says their products address all these concerns. Made primarily from non-genetically modified soybeans, the plant-based alternatives are free of harmful substances, absolutely safe. The company pointed out that the products share a similar look, feel and taste of the real thing. "We've done pilot taste tests with friends, family, and one sushi restaurant. Many admire the appearance and mouthfeel that our tuna product has as well as its nutritional benefits. Now we are struggling to improve our product until it's an exact match or tastes better than animal-based tuna, "added David Yeung.

Besides Omnifoods, Singapore companies are also exploring the alternative seafood market. Growthwell Group recently raised US $22 million to fund its attempt into shrimp, squid and crab made using chickpea protein. "Global demand for plant-based meats is also shooting up, with the value set to reach US $ 23. 2 billion by 2024, "said market research company Euromonitor.

Despite Kyle Tianshi being only a 15-year-old US high schooler, he has published five sci-fi novels. His fifth book Eventide was released in July. However, this may not be his most impressive achievement as Kyle just received the"Hero Award", a $20, 000 grand prize. It is the top honor in the California Youth Sustainability Awards. The competition aims to encourage and support young community leaders who are making a difference for sustainability in their communities by taking action for the planet.

Kyle, a sophomore from the Cambridge School in the US, received the honor for his portable invention called NEREID. The device can detect microscopic particles(粒子) in water by using a laser and microscope. These particles can be harmful to people and the environment. 

Kyle came up with the idea for the invention based on his experience growing up in San Diego, California, the US. People had no access to unpolluted drinking water and his parents asked him not to drink tap water. Kyle spent about $60 buying the tools needed to analyze the tap water：a laser, a microscope and a micro-computer. "It's incredibly powerful for the price, "Kyle said. Then he used their family's garage as his laboratory, doing research on the pollution of drinking water caused by micro-plastics.

Kyle hopes to bring to market a low-cost alternative tool for detecting micro-plastic pollution levels in drinking water. In this way, he can offer help to people who don't have access to water filtration(过滤) systems. He has applied for a patent.

Kyle said his sister Emily, a freshman at Stanford University, inspired his interest in environmental research. She was recognized nationally for developing a water collection device. They have founded the Clearwater Innovation program to advocate for clean water through social media platforms and organize community cleanup events. 

With a history of more than 6, 000 years, Chinese painting, originally  (pursue) by wealthy people, developed around 221 BCE during the Eastern Jin Dynasty. Then, it became popular around 581 CE as more and more people began to show(appreciate) of its beauty. 

Basic tools and materials for Chinese painting involve writing brushes, ink and paper. The Chinese painting brush is mostly made of goat, wolf or fox hair, is suitable for producing brushes that are both soft and stringy(有韧性). 

The ink stick is produced with a mixture of pine soot(松烟) and animal glue. It's used in combination with an ink stone. The painter wets the ink stone and then grinds(研磨) the ink stick on the stone,(make) the ink run so that it can be used for painting.

Many Chinese ancient artworks (create) on silk. However, silk was expensive that only very important paintings would use it. By the first century, when the early form of paper was invented, it had become a lot (cheap) to paint. 

Traditional Chinese painting enjoys worldwide fame  its original style, distinctive features and special techniques. It emphasizes harmony between man and nature. When looking at a Chinese painting, you may not  (initial) realize its complex concept. In fact, much remains (learn) about traditional Chinese painting and its elements. Through appreciating Chinese painting, you will have a better understanding of traditional Chinese culture and Chinese people. 

Ms Salomon had only been working at Sainsbury's for a year when she was diagnosed(诊断) with Alzheimer's disease. Before that, she had been 1 to leave her job as a bookkeeper because she was becoming increasingly 2 .

Upon being informed of her diagnosis, 3 , the Sainsbury's staffers started doing all they could to make sure that Ms Salomon felt comfortable and 4 . For the next four years, Sainsbury's did everything to keep Ms Salomon on the team. They changed her 5 ；they stayed in 6 with her family so they could provide 7 on her condition at work；they 8 retrained her. When the disease progressed, Sainsbury's even created an entirely 9 job for her as a "tote box cleaner".

In 2017, Ms Salomon received a medical 10 that said her Alzheimer's had progressed to the advanced stage, and she was 11 unemployable. Again, Sainsbury's kept her on the team.

Ms Salomon's 12 finally came to an end 6 months later, and though it was an emotional 13 , she was also relieved.

"There have been so many times Sainsbury's could have let her 14 , "Ms Salomon's son Doron said. "Instead, they have always 15 her, going above and beyond to make sure she's happy and feeling valued. On a human level, they have shown sensitivity, kindness and care. "

Now, an increasing number of cities are stopping using recycling services, partly out of fear that workers might contact the coronavirus from one another while sorting through used water bottles, food containers and boxes. One solution：Let robots do the job. 

Since the coronavirus took hold in the United States last month, AMP Robotics has seen a "significant"increase in orders for its robots that use artificial intelligence to sort through recycled material, and weed out trash. Some facilities that were looking at getting one or two robots are now saying, "We need quite a bit more. "The Colorado company's chief executive, Matanya Horowitz said, "It's all moving quite fast. "

Before the pandemic, automation(自动化) had been gradually replacing human work in a range of jobs, from call centers to warehouses and grocery stores, as companies looked to cut labor costs and improve profit. 

But labor and robotics experts say social-distancing directives, which are likely to continue in some form after the crisis becomes less strong, could cause more industries to accelerate their use of automation. And long-lasting worries about job losses or a broad unease about having machines control vital aspects of daily life could disappear as society sees the benefits of restructuring workplaces in ways that minimize close human contact. 

Recycling is one industry that may be altered permanently by the pandemic. Some workers, who earn as little as $10 an hour, have been concerned about coming to work during the crisis and some cities have been competing to find enough protective gear(防护装备) for all of their employees. Federal health officials have assured them that the risks of transmission from household refuse is low. But workers in recycling facilities often work side by side sorting material, making social distancing difficult. 

At AMP Robotics, executives like Mr Horowitz say their robots will enable recycling facilities to space out their employees, who stand at conveyor belts(传送带) weeding through the used plastic and paper. 

I'm rather good at using maps. But I forgot the maps and here we were, late afternoon, last day of vacation, my daughter, my cousin and I, driving along a two-lane highway in Oregon. No other car in sight, and the sun had just gone down. Where was that sweet little village?

It was supposed to be right along this river. We drove on, farther into the unknown, river always on the left as our guide. We kept passing farms and fields and now a few lights were coming out. In my head, I was doing a lot of self-criticism：Why didn't we start earlier, bring the map and drive on and on? My cousin and I were both impatient and stressed. My daughter, at least, was happy in the back seat, text-messaging a friend. I pulled up on the shoulder of the road to think.

Just then—WOW! Amazing! A new scene had appeared. Where did it come from? 

Right there, out of nowhere：a magical misty landscape. Fields stretched in silent purples, with rows of tall trees, darkening in the dusk. I turned the car engine off. All was silent in the hot summer air. Beside us, a plum-colored river hardly moved between a border of trees, its dark lazy water reflecting the last light of day. 

How breathtaking! Where had it been? If I had seen even a bit of this beauty while driving along, I could have stopped and taken a look. I had missed it all. 

We miss a lot, almost everything, in fact, in our world. Our task-focused filters(过滤器) take care of that, selecting only what we need. We need to get to work. Have some lunch. We see what we need to see, often for the purpose of survival. Gregory Bateson, speaking of beauty, said aesthetic judgment is selection of a fact. In our daily lives, who or what is doing the selecting? Can we make a change? Can we see further?

Gig workers, often referred to independent contractors(承包者) or temporary workers, are those such as delivery drivers and online sales hosts often enter into contracts with ondemand companies to provide services to their clients.

The guideline (release) early on Thursday by five central departments to solve practical problems that are being faced today and are on the horizon among employees and employers in the gig economy. 

In the past few years, with the rise of technology and the impact of the pandemic, the gig economy (provide) opportunities to many people across a number of sectors, according to Pang Shi, director of one department. She said the gig economy provides an important way for people to improve their incomes, and that for seniors, the (disable) or those with other difficulties, gig work provides less pressure than full­time employment. 

Gig workers often have higher work (efficient) because of new technology, (break) the previous working limits of time and space. "The gig economy is showing growing importance to the stability of the job market, (particular) facing current economic downturns, "Wei Xiang, professor from the University of Chinese Academy of Social Sciences, added.
