【推荐1】The days of having to remember your ID could soon be a thing of the past. The famous tourist town of Wuzhen, China, is now using facial recognition technology to act as its entry pass through the gates of the attraction. The system uses cameras to notice people as they approach the entry, and checks these against a database of registered visitors within a few seconds. The technology is thought to be up to 99.77 percent accurate and able to distinguish people better than a human.

Wuzhen is a popular tourist town with visitors going there in large numbers to see its stunning river system and museums.A web firm created the system. When people now check in to their accommodation, they will have their photo taken and uploaded to a central database. Upon leaving and re-entering the town, the system will re-check that they are still a guest at a hotel, before allowing them back in.

The technology is being used to track the 5,000 visitors that stay in the town’s hotels every day. Yuan Qinglin, director of the Institute of Deep Learning of the web firm said, “With our technology, you don’t need to give your ID.When you are approaching a gate, it will take a photo of you and compare that photo to the database.” Wuzhen used to monitor its visitors using a ticket-entry system, but this could easily be abused. It was discovered that some people were sharing their tickets to avoid paying.

This system is based on neural networks, which can process huge amounts of data—more than one billion faces. As well as recognizing faces, the system can discover facial movements, so it can’t be fooled by holding a mask.This web firm is also using the software for employee entry at its Beijing headquarters.

【推荐2】University of New South Wales has launched its new 12-month Women in Maths & Science Champions Program designed to give women the skills and confidence to build their public recognition and set up a connected network of women in maths and science. The first group of 30 female PhD students started in August this year, and the second group of 19 early- career researchers was formally announced yesterday.

Over the 12 months, the champions complete at least 20 hours of related activities as part of a community of representatives who will influence and inspire women to pursue a career in maths and science. The activities are varied, ranging from visiting schools and conducting science presentations, to attending conferences and creating content for social media. At the end of the program, PhD champions have the chance to apply everything they’ve learned to the Postgraduate Research Competition. Above all, participating is a requirement for program completion.

Rose O’Dea, a member of the first group, is a PhD candidate at the School of Biological, Earth and Environmental Sciences. She said, “I’m excited about the opportunity to work with school children. I hope to inspire some girls so they see not all scientists are older men in lab coals and that science is quite diverse and means different things depending on who you are.”

Dr. Mariana Mayer Pinto is an early-career researcher at the School of Biological, Earth and Environmental Sciences, where she mainly works with marine (海洋的) ecologists. She is originally from Brazil and said that being a woman from a developing country meant she knew the struggles that lack of role models can create. “You can’t be what you can’t see! I always have the hope that I can change the world bit by bit, and if one little girl says she can become a scientist because I talked to them, that’d be awesome, and that would make everything worth it.”

【推荐2】The world's largest iceberg (冰山)is floating toward the island of South Georgia in the southern Atlantic Ocean. Scientists fear the iceberg could crash into the island and block major feeding areas for a large population of penguins (企鹅)and seals.

Satellite images show the iceberg has remained in one piece. It is estimated to be about 150 kilometers long and 48 kilometers wide. It is traveling at one kilometer an hour and is on a path to hit South Georgia in around 30 days.

The British Antarctic Survey says it is concerned that if the iceberg hits the island, it could prevent the penguins and seals from reaching food supplies.

Professor Geraint Tarling, an ecologist with the Antarctic Survey, says right now is the time of year when seals and penguins spend a lot of time caring for their young. This means the distance that parents have to travel to find food is important.

"That means they have to go a lot further, they have to go around the iceberg, or to actually go further to find sources of food," Tarling said. "And that time is quite important at this particular period of their life cycle."

The breaking off of icebergs from Antarctica is a natural process. But the process is changing with climate change. " What we 're seeing with models and some observations now is the rate at which this is happening is increasing. And so, this might become more of a usual thing into the future," Tarling said.

The iceberg also could damage South Georgia's valuable fishing industry. Fishers pay for the rights to catch Patagonian toothfish, icefish and krill (磷虾)in waters off the island.

Officials are hoping that changing weather patterns could direct the iceberg out into the open ocean, where it would, in time, break up and melt.

【推荐3】Next-generation fitness equipment and robots help you cook dinner. Those are a few of the countless new products expected to be shown next week at CES, the annual tech conference that typically sets the tone for the biggest trends of the year. Home automation（自动化）, health and 5G will once again be hot topics, but many companies will also introduce pandemic-specific features to reflect our increased time at home.

Each year, reporters, exhibitors and investors typically explore Las Vegas showrooms filled with giant TVs, smart cars and robots, but CES will be online only for the first time in its 54-year history due to Covid-19.

The Consumer Technology Association, the nonprofit behind the four-day event starting Monday, said 1,800 exhibitors from around the world will fill its "digital venue" this year—a number that's down significantly from 4,000 in-person exhibitors last year. The move will allow tech companies from countries which have never attended before to take part in the online exhibition, but could also make it harder for smaller companies to get noticed without a physical showroom.

Registered attendees will be able to stream and re-watch keynotes from companies such as Verizon (VZ) and General Motors (GM), tune in to breakout sessions -- about how, for example, technology is playing a role in vaccine deployment（疫苗的应用）—and search through a registry of exhibitors to watch new product presentations.

It'll lack some of the signature ingredients（因素）of the trade show, such as hands-on time with the latest small machines and networking. But the technology that makes our lives more connected and convenient will still gain popularity.

【推荐1】Social media is one of the fastest growing industries in today’s world. A study conducted by the US Pew Research Center showed that 92 percent of teenagers go online daily. The wide spread of social media has changed nearly all parts of teenagers’ lives.

• Changing relationships

High school student Elly Cooper from Illinois said social media often reduces face- to-face communication. “It makes in-person relationships harder because of people’s attention given to their phones instead of their boyfriends or girlfriends,” Cooper said.

Yet, some people believe social media has made it easier to start relationships with anyone from anywhere. Beth Kaplan from Illinois met her long-distance friend through social media. He currently lives in Scotland, but they’re still able to frequently communicate with each other. “I can feel close to someone that I’m talking to via FaceTime,” Kaplan said.

• Wanting to be “liked”

The rise of social media has changed the way teenagers see themselves. The 19- year-old Essena O’Neill announced on the social networking service Instagram that she was quitting social media because it made her unable to stop thinking about appearing perfect online. Negative comments also can do great damage to a teenager’s self-esteem. Teenagers who get negative comments can’t help but feel hurt.

• Opening new doors

However, Armin Korsos, a student from Illinois, takes advantage of the comments he receives over social media to improve his videos on the social networking site YouTube. “Social media can help people show themselves and their talents to the world in a way that has never been possible before,” Korsos said.

【推荐2】Summer is that time of this year 2020 when everyone looks to escape from the boring activities of life. So bring your kids to join us to have fun in the summer camp.

Outdoor Word Game:

All you need to do is setting up many huge letters that can be easily moved. These letters will help kids spell out certain words. Teenagers would also love something like this as it gives them the opportunity to spend their time in learning new words.

Spray Painting:

To bring out the creativity in a person, an activity centered on spray painting is the perfect way to get those creative juices flowing. All you need to do is providing plain white T-shirt and some cans of colored spray paint. It will be quite surprising to see some of the original ideas that will flow from individuals.

Outdoor Twister:

A person will be in charge of monitoring the game and will call out colors which can be placed outdoors. Participants have the task of placing either their hands or legs on the same color. A fun and exciting game focuses on hand-eye coordination (协调).

The Maze (迷宫):

One of the most fun games is the hallway maze game where a maze is constructed from either toilet paper or strings of paper. The chosen participant is then asked to make his way through the maze within a limited time without touching paper. This is one of the best and entertaining summer camp ideas for kids and adults also.

【推荐3】An experience in a national park is exciting. But to make sure of a safe and pleasant trip, you should remember the following rules; Always keep food in safe and sealed containers.

Leaving food in the open is an invitation to animals. It is best to keep food in closed containers in a locked car. Garbage should be treated in the same way. Be careful with the park environment while walking.

To avoid meeting with bears –make your presence known. Make loud noises, shout and sing. Be especially careful in a thick bush or along streams where water makes noises.

Bells are not suggested as the sound does not carry well.

Do not approach wild animals.

Visitors have been attacked by wild animals. They may appear tame but are wild and dangerous. Many animals run faster than you can imagine.

Always put out campfires.

They are dangerous when left unattended and can cause forest fires. Always put the campfires out completely with water before leaving the area.

Be sure to carry plenty of water.

Cool, clear stream water is not as clean as it looks! Drinking untreated water can make you ill. You’d better carry enough drinking water. If you must use water from lakes or streams, boil it for one minute.

Seat belts are required by law.

Always wear your seat belts while driving! Slow down at dawn and drive carefully when it is dark. Watch carefully at all times for people and animals on roadways.

Do not feed the wildlife.

They’ll lose their desire for natural foods and become beggars. They may bite, and/or spread disease.
