What’s on your travel list for 2021? I’ve consulted several travel experts to find out the top places in the USA worth visiting in 2021.

Where: New Orleans, Louisiana

Why: New Orleans is known for its music and food—not to mention the festivals.

It has about 130 festivals each year, so there’s really no bad time to visit. Bourbon Street is the obvious choice for food, drink and jazz and it’s definitely a must-visit location, especially for the first timers to the city.

Where: Vail, Colorado

Why: Vail is the perfect destination for travelers looking to find almost everything in one central spot. Stay at the amazing Four Seasons Resort and Residences Vail a few steps away from Vail Village, a popular town with cobblestone(鹅卵石) steets for wandering leisurely. The country’s largest free transportation system runs frequently, making it easy to access almost anywhere from Vail Village to Lionshead Village.

Where: Hudson Valley, New York

Why: The Hudson Valley is where New Yorkers go to escape the city when they need a healthy dose of nature and relaxation. Just an hour and half north of New York City, the Hudson Valley is made up of small, impossibly charming towns, where the air is fresher and things do move slower in the mountains.

Lewis Carroll was the pen-name of Charles Lutwidge Dodgson, an English writer and author of two of the best loved children’s books in English literature — Alice’s Adventures in Wonderland and Through the Looking-Glass. The characters and phrases from these books have entered and become part of the English lexicon (词典) in a way that was comparable to those from Shakespeare’s works.

Charles Dodgson was born on January 27, 1832 and spent the first eleven years of his life at Warrington. Dodgson was educated first by homeschooling, then at boarding schools in Richmond and at Rugby, and finally at Charist Church College, Oxford. In later life, he remembered his boarding school experience with no fondness. Still, he was an excellent student and did very well academically throughout. For all his brilliance or perhaps because of it, he couldn’t be bothered to spend long hours studying and so he didn’t. If things came easily, that was fine; if they didn’t, well, that doesn’t seem to have bothered him very much.

His book Alice’s Adventures in Wonderland first came into being in 1862 as a story he made up for Alice Liddell, the ten-year-old daughter of his friend Dean Henry Liddell. Later he wrote it down and showed the book, illustrated with his own drawings, to another friend, the fairy tale writer George Macdonald and his children. They loved it and enthusiastically urged him to get it published. Accordingly, Dodgson revised it for publication. And in 1865, with illustrations more professionally done by Sir John Tenniel, it became an immediate bestseller. Its sequel(续集)Through the Looking-Glass proved equally popular.

15-year-old Max produced the Vybpro, a wearable wristband (腕带) which warns users whenever they are about to touch their faces. The gesture has been recognized as one of the key ways that COVID-19 can be spread, making it a potentially life-saving invention.

He first hit on the excellent idea two years ago for the purpose of reducing the spread of the cold and flue. After both of Max’s parents were infected with COVID-19 four months ago, however, he put in all his effort to develop a working prototype (模型).

Worn on both wrists, the intelligent device is expected to sell for £ 89. It uses position-sending technology algorithms (算法) to tell between predicted face touching and other hand motions. Then the device warns users of hand gestures that are dangerously near the face.

“We came up with the concept a few years ago when my family was repeatedly catching cold and flue viruses from traveling in and out of London and I could see how easy it was to pick up germs especially from using public transport,” said Max. “It was only when the World Health Organization (WHO) began suggesting people avoid touching their eyes, noses and faces to stop the spread of viruses from contaminated surfaces did I realize that it could play a part in slowing the spread of COVID-19.”

Max, who is from Bristol, launched a £ 60,000 crowdfunding campaign (众筹活动) on Kickstarter earlier this week to further his project and turn the prototype into a public reality. “The main task of this project is not to make money, but to get it onto the wrists of those it can help keep safe. Any profits made from early sales through the crowdfunding site will be reinvested into providing free devices for organizations that help people such as National Health Service (NHS) staff and nursing homes.

The moment you open your eyes in the morning, you can feel sweat running down your body, even if you’re barely moving at all. That’s what most people in China felt like this summer. In fact, the entire northern hemisphere(半球)saw high temperatures in July.

The Arctic Circle was no exception. Temperatures in the city of Norilsk, which is in the Arctic Circle, reached a record high of 32℃, the Atlantic reported. Temperatures there are usually just 10℃ at this time of the year.

The heat wave in the Arctic is mainly a long-term result of global warming, according to the Chinese Academy of Meteorological Sciences. Actually, while the whole world is getting warmer, the Arctic is warming twice as fast as the rest of the planet. This is called the polar amplification effect(极地放大效应).

The most direct impact of Arctic warming is the melting of Arctic ice. According to NASA, Arctic sea ice is now disappearing at a rate of 13.2 percent every 10 years. NASA said that if this continues, the Arctic will have no ice by the year 2040. This has put some Arctic animals, like polar bears, in danger. The ice that the bears live on has shrunk, the Toronto Star reported. Melting ice can also cause sea levels to rise in the long term. Since 1993, sea levels have risen at a rate of 3.2cm every 10 years, the Guardian reported. Some countries, such as Tuvalu(图瓦卢)in the South Pacific Ocean and Maldives(马尔代夫)in the Indian Ocean, are at risk of disappearing into the sea.
