There are numerous amusement parks all over the world. A famous magazine, Amusement Today, does a survey among park lovers every year both in the US and overseas, based on which, “Top 5 List of the Best Amusement Parks in the World” has come out as follows:

Disneyland, California

Disneyland is a theme park in Anaheim, California, the US. More than 515 million guests have travelled to this American landmark from around the world since the park first opened to guests on July 17, 1955. The park consists of many world-famous sections, such as Main Street, Adventure Land, New Orleans Square, and so on.

Magic Kingdom, Disney World, Florida

Magic Kingdom is a theme park within the Walt Disney World Resort in Lake Buena Vista, Florida, near Orlando opened on October 1, 1971. It is the most famous theme park in Florida. The park’s design and attractions don’t make much difference from Disneyland Park in Anaheim.

EPCOT, Disney World, Florida

EPCOT is the second theme park built at the Walt Disney World Resort near Orlando, Florida. The park opened on October 1, 1982, and was named EPCOT Centre from 1982 to 1993. It was the largest Disney theme park in the world until 1998, when Disney’s Animal Kingdom opened.

Disney-MGM Studios, Florida

MGM’s streets are the home for some great movie-themed attractions with a history of less than 30 years. With the addition of the Twilight Zone Tower of Terror and the Rock ‘N’ Roller Coaster, the park is now home to Disney World’s most thrilling rides.

Universal Studios, Florida

Go behind the scenes, beyond the screen and jump right into the action of your favourite movies at Universal Studios, the number one movie and TV theme park in the world.

Endless queues and long waits at the ticket inspection desks at China’s major train stations were signature of the Spring Festival travel rush before this year. Every year, as the country’s biggest national holiday unfolded a huge flow of travelers would leave staff at the check-in desks facing a dilemma.

But with the installment (安装) of artificial intelligence (AI) in dozens of train stations this year, including a facial recognition system which is able to process passenger identification within five seconds and therefore speed up the waiting process, busy scenes started to become something of the past.

When a passenger approaches the camera inside the facial recognition system at the station, it scans his face and then quickly compares it with the photograph shown on his identification card in real time. If the information matches, the barrier gates will open and allow the passenger to go through.

Such use of facial recognition technology is in line with discussions heard at the recent two sessions meeting, a key annual political event, which focused on the widespread application of a security network named Tianwang (“Sky Net” in English) currently being used by China’s public security department.

The network, according to reports by the People Daily, has the potential to recognize the facial features of anyone in the world and match them on the spot with photographs on a database of criminal suspects. In fact, it can analyze photographic identity so quickly that it can scan every single Chinese face on the planet in just one second, and it would only take two seconds to scan every face in the world, with an accuracy rate of up to 99.8 percent.

Those are just two examples that highlight the development of Chinese visual AI technology, which industry insiders predict could contribute to powerful growth in the global technology sector this year.

Some of the world’s most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO( United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.

Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.

It’s Jason Moran’s job to help change that. As the Kennedy Center’s artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.

“Jazz seems like it’s not really a part of the American appetite,” Moran tells National Public Radio’s reporter Neal Conan. “What I’m hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and write anymore. It’s actually color, and it’s actually digital.”

Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can’t be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,” says Moran.

Last year, Moran worked on a project that arranged Fats Waller’s music for a dance party, “Just to kind of put it back in the mind that Waller is dance music as much as it is concert music,” says Moran. “For me, it’s the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context,” says Moran, “so I want to continue those dialogues. Those are the things I want to foster.”

Ways to get your laughter back Through all my school years, laughter was part of my life. My best friend and I came up with a name for the "really good" laughs. We called them Belly Rolls. That may sound silly, but it is the truth. However, after I realized I had "lost" my laughter, the first thing I thought of was how silly I was going to look and sound.    16    . This is how you do it.

    17    . It will be a forced laugh. I know it sounds silly, but trust me, if you can't laugh by yourself and be comfortable, it's even harder to laugh in a social situation when you think people are judging you.

Watch only funny programs on TV and at the movies. Be very selective about what you watch.    18    . If you cannot give up those programs absolutely, then watch only half an hour of them a day. Give yourself a fighting chance and make it a point to bring laughter into your life.

Invite your friends and family to make it funny! Don't wait too long before you start laughing socially. Ask someone close to you to point out the fun in life. Maybe they can promise to tell a joke to you every day or sit with you during a half-hour situation comedy.    19    .

While driving, go over your day and remember everything funny.    20    . Not only will this help you laugh more, but it will keep you feeling happy. If you are spending all your time remembering the good times you had for the day, it doesn't leave much time to think negatively！
