【推荐1】John James Audubon was curious about some birds he saw near his Mill Grove home in the early 1800s. He caught a few of them, tied a thin silver string to their legs, and released them. The next year, the birds returned. Audubon realized that his feathered neighbors returned to the same nesting spot each year.
People had tried attaching bands to birds' legs before Audubon's experiment. More than 2,000 years ago, Rome officers sent messages attached to birds to keep their armies informed. Audubon's experiment, however, is the first example of banding used to learn more about the movements of the wild birds in North America.
Today, only trained scientists are permitted to band birds. An organization known as the Bird Banding Laboratory（BBL）supplies official aluminum bands. Each band is stamped with a unique identification number. Researchers collect information about banded bird's species, weight, sex, age, wingspan and general health. That information is shared with the BBL.
Modern technology has taken bird banding to a new level. Today, transmitters（发射器）that come in all kinds of sizes are used. They can be attached to the leg, the neck, the back, or even a bird's feathers.
Researchers can learn many things from a banded bird, such as patterns in nesting, feeding and migration. Banded information also gives researchers a sense of the general health of a group of birds. And information about the general health of birds helps scientists understand the general health of the environment, which is good for humans too.

【推荐2】Sales of Apple’s new iPhone 11 in China began on Friday, but were met with a cooler reception from consumers than in previous years. Unlike in previous years, no long lines were seen outside Chinese shops on Friday for the new iPhone, and the product release only made the headlines in a few media outlets.
Huawei unveiled（公布）its Mate 30 smartphone series on Thursday night. Its new devices have won consumers’ hearts at home and abroad. Many compared it with Apple’s new iPhone 11, saying that beats the new iPhone in terms of innovation and quality. One customer surnamed Zhao, an IT specialist who pre-ordered a Mate 30 Pro on Friday, said that he chose Mate 30 without hesitation. Zhao said, “It’s obvious that Huawei’s new phone with its advanced 5G mode would lead the future global telecommunications market, and its new innovative features in gesture and side control attracted my attention, too.”
In contrast with iPhone 11’s lukewarm（冷淡的）sales, Chinese netizens have engaged in discussions on Mate 30 and Mate 30 Pro. An online poll on the Mate 30 and iPhone 11 on Weibo on Friday showed that more than 60 percent of netizens chose the Mate 30, while less than 20 percent chose the iPhone 11. Many chose Huawei not out of patriotism but for its technology.

Digital Learning
Learning communication can be of greater quantity and quality. Digital tools and activities can be used to provide each student rich, timely, targeted feedback on their work, increase the authenticity (真实性) and applicability of student assessment, and document the unique knowledge and skills attained by each student for employment or further study.
Learning relationships can be more critical, creative, competitive and collaborative. Digital tools and activities can be used to increase academic discourse, peer learning, and leadership and teamwork both in and outside of the classroom, and to make transparent data-based teaching and learning decisions from the class to university level.
Learning experiences can be more interactive and immersive (沉浸式的). Digital tools and activities can be used to shift learners from passive consumers of static content to active creators and curators (管理者) of digital content that can be remixed and repurposed in a quickly changing knowledge economy.
Learning stakeholders can be more invested and involved. Digital tools and activities can be researched, developed and deployed through each schools’ support and development of faculty, professional services’ expertise (专长, 专门知识) and resources, and students as inspiration, agency and evidence of success.

【推荐1】Today, roller skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the idea of skating didn't exist. That changed because of a man named Joseph Merlin. He was a man of ideas and dreams. So people called him a dreamer. Merlin liked playing the violin in his free time as well.
One day , Merlin received an invitation to attend a fancy dress ball. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.
Merlin tried different ways. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.
On the night of the party Merlin skated into the room playing his violin. Everyone was astonished to see him. There was just one problem. Merlin had no way to stop his roller skates.
He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin's grand entrance for a long time!

【推荐2】An unconventional method for growing rice has been found to increase yields(产量) by 20 to 50 percent. Reports from China, India, Southeast Asia and Africa suggest that average yield increases of 20 to 50 percent are regularly being achieved by farmers adopting the "system of rice intensification(集约化)"(SRI)，which needs one-tenth as many seeds and aims to stimulate the root system of plants rather than trying to increase yields in the conventional way by using improved seeds and fertilizers.
The idea of using less to gain more is seen as an important innovation(革新) for adapting farming to climate change and a way to increase yields at a time when human populations are growing fast but traditional plant breeding and genetically modified techniques have failed to increase yields more than a few percentage points, says Norman Uphoff, professor of international agriculture at Cornell.
The new way to grow rice needs only half as much water, and is proving most popular in water-stressed countries, says Tavseef Mairaj Shah, a Ph.D. researcher. "Rice growing in Kashmir largely depends on irrigation systems that draw water from the river Jhelum. But climate change is leading to drier winters, untimely rains, and warmer summers."
“SRI is a great technique, not just from the water-saving perspective but because it offers better yields and soil conditions. Different studies, both at the experimental level and farmer-participative level, have shown that SRl improves yields with less water.” Shah adds.
Some academic, the global seed industry and the international community once rejected reports of “fantastic” yields, accusing farmers of falsifying(篡改）records and researchers of carelessness and "non-science". But more than 600 articles, checked by SRI International at Cornell University, have shown benefits.
Uphoff says, “Attitudes are changing.The original hostility(敌意) has gone." However, the early opposition has resulted in comparatively little scientific research being conducted into SRI and a slow understanding by funders.

【推荐3】The Internet, search engines, virtual worlds. Have you ever got the feeling that you’re living in a science fiction?
Well, indeed you are.
For more than a century, inventors have been driven to create what sci-fi writers have imagined long before. Buck Rogers inspired a generation of scientists excited about space exploration. Ray Bradbury predicted home-theater systems. William Gibson dreamed up the Internet while writing Neuromancer on a typewriter. Not long after him, Neal Stephenson predicted virtual worlds in his 1991 novel Snow Crash. One of his readers was Philip Rosedale, who loved it so much that he wanted to build a virtual world based on it.
By the late 1990s, technology caught up to the novel, and Rosedale built the virtual world Second Life based on the “Metaverse” from the novel. With 1 million active users, Second Life offers virtual shops, bars, houses and even virtual television studios with virtual celebrities (名人) on virtual talk shows.
“I think it is pretty much what I imagined,” Stephenson says. “I just shoot for the stars, while he makes great things happen.”
But Snow Crash is a dark book. The world in the novel is filled with criminals, violence and environmental problems.
“Science fiction not only puts stars in our hands, it also helps us see the meaning of our work,” Philip Rosedale admits. “It makes it possible for us to see what all of our efforts could eventually lead to.”
In fact, most science fiction authors admit that their work is usually cautionary (警示性的). “While the inventors are rushing ahead and excited about this possibility or that possibility, we’re always standing there warning, ‘Hang on just a second. Let’s think about this a little more’” author William Gibson says. “But most of them will ignore you because they think they already know all things about any given hot topic of the day. But if you can convince them that you’re talking about a planet millions of miles away and hundreds of years in the future or the past, you can actually get them to examine more closely what’s going on right now.”
