【推荐1】Mexico is a great destination that attracts many tourists by its breathtaking landscapes (风景) and architecture of the ancient Mayan civilization. Here let’s take a look at the most beautiful beaches in Mexico.

Tulum Beach

In the south of the Riviera Maya, Tulum Beach is not only an amazing place for those who love the sea and sunshine, but also a great place for visitors who are crazy about understanding the ancient culture of mankind. Around the coast, there are many modern hotels to serve every of your needs.

Playa Norte

Playa Norte has a very clean blue water, so many tourists appreciate it. What makes Playa Norte so unique is the good combination of daytime relaxation and exciting nightlife. If you have the opportunity to set foot on this beautiful beach, you must watch the whole sunset on the sea. That scene is really romantic.

Cancun Beach

Near a busy city, the beach here impresses people by its wilderness. With deep blue water, fine white sand and a warm and mild climate all year round, Cancun Beach is known as a tourist paradise (天堂) in Mexico. In addition to sunbathing here, visitors also have the opportunity to play with lovely dolphins.

Akumal Beach

Akumal is known to be the great diving spot in Mexico. This Beach is home to many rare sea turtles as well as tropical marine (海洋的) species. Akumal beach is calm, so it is quite safe, suitable for relaxing activities. When diving at Akumal, visitors often swim with lovely sea turtles. So, spend a relaxing day on the beautiful beach and then go to a nearby restaurant to enjoy fresh seafood.

【推荐3】Some of the Most Beautiful National Parks in the UK

Snowdonia

North Wales’s national park boasts mountain and sea views: Several of its peaks gaze across to Ireland and it has miles of sandy beaches. You can climb Wales’s highest mountain without working up a sweat by catching an old-fashioned train. Those who dislike excitement can choose zip lines, bounce down mountain bike trails or catch breaks at an inland surfing.

Cairngorms

The UK’s biggest national park is home to its mightiest mountains: Five out of six of Scotland’s highest peaks are found here. Lying in the heart of the Highlands, the Cairngorms mountain range still has vast areas of pure wilderness and is one of the chilliest places in the country. For much of the year, its peaks are blanketed in snow and you can ski there in winter.

Peak District

Sandwiched between Manchester and Sheffield, England’s oldest national park has two personalities: A tough and a gentle side. In the north are dramatic edges like Kinder Scout which rewards adventurous walkers with stark (荒凉的) views. Venture south for the lower, greener, grass-covered valleys of the White Peak. Walk along the Ecclesbourne Valley to experience both in one day.

New Forest

The New Forest is surprisingly old: William the Conqueror named it when he used to hunt deer and wild pigs here nearly 1, 000 years ago. Confusingly, this beautiful corner of southern England isn't completely covered in woodland either —it also has acres of wild land and miles of pebbly (布满鹅卵石的), muddy coast. The terrain is gentle, and you’re guaranteed a sighting of its free-walking horses.

【推荐1】From skateboarding to Fleetwood Mac, TikTok users got creative in a pandemic (流行病) year with new songs, dances and shows in 60 seconds or less.

The social media video app on Wednesday shared its list of top 100 videos, creators and trends in America during 2020. “These videos brought joy and inspiration to millions of Americans in the rough year,” said Kudzi Chikumbu, director of creator community at TikTok.

The platform has been widely associated with Generation Z (people born after 1996), millennials (people born in the 1980s or 1990s) and influencers who have started careers based on the shared videos.

The Weeknd's Blinding Lights and Jason Derulo's Savage Love inspired TikTok dance challenges that made them among the top songs used on the app.

For some TikTok creators, the pandemic itself became inspiration to create a connection with other users. Comedian Caitlin Reilly used the app during quarantine (隔离) to make fun of those annoying coworkers for one of the top liked videos. And singer Curtis Roach made an song for the endless days at home with his song Bored in the House.

The second most popular video was an Idaho man named Nathan Apodaca who shot to fame after coolly singing Dreams by Fleetwood Mac, while skateboarding on a highway.

But the most liked TikTok video was awarded to Bella Poarch with 45 million followers, who created a simple but interesting video with a few seconds of well-timed head nods and eye rolls.

While the app might be designed for youth, Chikumbu said that the growth of TikTok this year has pushed it more into mainstream culture. “You're seeing everyone from the teenager to the college students with their parents and then their grandparents all making videos,” said Chikumbu. “And now TikTok truly transcends generations, particularly in this year when people had a lot of time to dig in and not only watch, but try.”

【推荐3】Student scientists from the Indian Institute of Technology Madras recently demonstrated the power of combining hardware with artificial intelligence by developing a water assessment device. The team won the $ 200,000 top prize at IBM’s Global Call For Code Challenge for 2021 for their innovative technology.

Developed by the team that calls itself “Saaf Water,” the device has a lot of uses. The low-cost device could help save millions of lives in India if deployed on the large-scale. It not only senses decontaminated (净化) water but also provides a comprehensive summary of the water quality while suggesting purifying methods.

Using IBM Cloud and IBM Watson, the students developed the tech to especially cater to rural areas in India. Saaf Water was in theory when one of the developer, Hrishikesh Bhandari’s mother fell ill due to unknown consumption of contaminated water, which came from a public ground water source.

“When we came back to Goa, her treatment was going on and the doctor said it’s due to a very rare disease caused due to polluted water,”Bhandari told lndiatimes. Three months into her treatment, Bhandari and her teammates decided to develop Saaf Water in hopes of preventing such kind of disasters.

Saaf Water timely monitors the water and informs the community in real time. In addition, Saaf Water also suggests purification (净化) methods that may be best for different locations and geographies.

Saaf Water’s goal is simple and straightforward. With their breathtaking machine, they give local communities the power to save lives. The data is studied in real time by Saaf Water, which does analysis of the contamination.
