One of the most successful singers of the twentieth century, Ella Fitzgerald has made several different styles of her own. She was born in Virginia but was brought up in an orphanage in Yonkers, New York. Chick Webb spotted her in an amateur competition when she was sixteen. He engaged her to sing with his band and when he died in 1939, she took over.

    Unlike Bessie Smith, Ella Fitzgerald taught herself the sentimental music so popular in the 1930's — songs like “My Heart Belongs to Daddy”— and her recordings became best-sellers. During the 1940's she developed her own “scat singing” — a breathless, nonsense—syllable style—for songs like “Flying Home” and “Lady Be Good.”

    Ella Fitzgerald was the perfect musical partner for her friend, the trumpeter Louis Armstrong, matching him in warmth and artistry. “I just like music, period,” she said. “To me, it's a story. There's only one thing better than singing…. It's more singing.”

    While beach vacations may be a great way to take your mind off work, lakes surrounded by mountains make for an even grander experience. If you are looking for come peace on your vacation, we have some recommendations for you in the Caucasus (高加索).

Lake Sevan

    Lake Sevan is situated in the central part of Armenia, in the Gegharkumk province. It is the largest lake in Armenia, located 6,200ft above sea level. Along the lake shore, there are various accommodations such as resorts and hotels with plenty of activities to partake in such as windsurfing, swimming and sunbathing. While there, do not forget to visit one of the famous cultural monuments, the Sevanavank Monastery, and it offers a great view of the lake as well.

Lake Paravani

    Lake Paravani, located at 6,801ft above sea level, is in the south of Georgia, near the Javakheti plateau. At this level, altitude sickness can occur and it is a good idea to be prepared to adapt to it properly, or bring medication for altitude sickness. Being a volcanic lake makes for a more interesting: experience. The lake is best known for fishing. Do not come home during the winter months when the lake freezes.

Lake Cildir

    Lake Cildir is located in the Ardahan province. East Turkey, near the borders of Georgia and Armenia. It is the second largest freshwater lake of Eastern Turkey, and many tourists are not aware of this beautiful attraction. Lake Cildir is surrounded by mountains of the Caucasus. The lake freezes during late November. If the winter is not extremely cold, you can try some lake activities like ice skating and ice fishing.

Lake Van

    Lake Van is the must visit of all lakes in this list. The largest lake in Turkey. Lake Van is located on the eastern shore of Turkey and is also the most accessible lake here. It's situated at 5,380ft above sea level, and unique to lakes around the world, the water is high in salt content.

    It's well-known that meditation (冥想) has many benefits, but do you know how to practice it for a beginner?

    Set a proper scene

    Find a space for meditation. It should be private and quiet. Make sure the temperature is comfortable. Sit on a cushion (垫子) if the floor is uncomfortable. You may play soft music if you like.
                   

    Take a moment to loosen up. Remember that the goal of meditation is to relax. Loosen your clothing, remove your shoes and have a good stretch. Do your best to ease any muscle tension that might keep you from achieving relaxation. Make an effort to relax your facial muscles.

    Focus on your breath

    Sit down in the space you've prepared. Close your eyes and breathe. Each time you breathe in, count “one”. Each time you breathe out, count “one”. The idea is to strengthen being in the moment — the last breath doesn't matter, and the next one doesn't matter; only this one matters.

    Feel your breath inflate (胀大) your lungs and push on your diaphragm (隔膜). Feel how sweet it is to inhale the fresh air. As you do this, your body will gradually begin to relax and all of your attention will be centered within your mind.

    Return to real life

    Once you feel fully centered in your mind, allow yourself to gradually drift back to real life. Move your fingers and toes and slowly wake your body up. Open your eyes and remain there for a few minutes until your senses come back, and then slowly stand up.

    Even if you can't make it fully into your mind, you still get some benefits from it. If you want to feel better, you just need to practice. Set about 10 minutes around the same time every day and repeat this exercise.

    One spring day, once the flowers have begun to open, a bee will hover (盘旋) and zip through your yard and dive-bomb your picnic table. While you're thinking about avoiding an attack, that bee is focused on something else entirely: me.

    A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, straw-like tongue into a hundred or so flowers. When the bee has had her fill, she'll fly home. There the bee will deposit what she has got into the mouth of one of her co-workers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the comb. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4,000 flowers, and yet will produce only one-twelfth of a tea spoon of me.

The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally—I never go bad.

Alas, my good health is not guaranteed. The problem lies in the growth of industrial agriculture and the use of pest control chemicals, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit I'd appreciate your letting your own garden grow just a little wild My future depends on all of us fostering spring and summers wild flowers, thus helping the bees, who give so much—to you, to me—without ever asking for anything in return..

Bruce, a parrot missing part of his beak （喙）,  creatively uses stones to clean feathers （羽毛）,  highlighting advanced intelligence in parrots. 

Bruce lost the upper part of his beak in 2012 and was sent to live at a reserve in New Zealand. The defect made Bruce unable to search for food on his own, let alone keep his feathers clean with his beak. But in 2021, when comparative psychologist Bastos arrived at the reserve with colleagues to study parrots, zookeepers reported something strange：Bruce had seemingly figured out how to select and use small stones to clean his own feathers with his beak. 

Over nine days, the team kept a close eye on Bruce, quickly taking, videos if he started cleaning his feathers. It turned out that Bruce had indeed invented his own way to do so, the researchers reported in Scientific Reports. 

"It's crazy because the behavior was not from the wild, " Bastos says. When Bruce arrived at the reserve, he was too young to learn how to clean his feathers. And no other bird in the reserve uses stones in this way. "It seems like he just invented this tool use for himself, " she says. 

Tool use is just one of parrots' many talents. They're famous for copying and even understanding human speech. Some species can also solve complex puzzles, like how to enter a covered rubbish bin or practice self-control. 

For a concept as abstract （抽象的） as intelligence, it's challenging to develop a definition that applies across animals. Researchers often point to features once thought to make humans special—enhanced learning, memory, attention and movement control—as signs of advanced skills. However, many of these abilities can also be seen in parrots, as well as other animals like chimpanzees, dolphins and elephants. 

"Parrots are our evolutionary （进化的） mirror image. These brilliant birds may teach us about how humanlike intelligence can appear, " behavioral ecologist Antone wrote in his 2022 book The Parrot in the Mirror. With powerful brains and a preference for words, these birds are "the very best example, " he writes,  "of nature's 'other try' at humanlike intelligence. "
