Have you ever been into a cave? If not, please follow us and explore some of the most beautiful caves from around the world!
Marble Caves
Located in the center of Lake General Carrera, the Marble Caves in Chico, Chile, are only accessible by boat. The surrounding crystal clear waters allow visitors to see the rock formations beneath them while the rock ceilings above change color (depending on the writer levels and the season). The best time to visit: during sunrise and sunset, when the sun's rays light up the cave walls, making it an experience to remember.
Reed Flute Cave
Reed F1ute Cave known as "the Palace of Natural Arts" is located in the northwest of Guilin in southern China. The limestone cave offers a grand fairyland of stalactites (钟乳石), stone pillars, stone curtains, birds, plants and animals in fantastic shapes and colors.
Fingal's Cave
This incredible sea cave is located on the uninhabited island of Staffa in Scotland. The cave's size, shape, and naturally—arched (拱形的) roof combine with the waves to create strange sounds that enhance its cathedral—like atmosphere.
The Blue Grotto
The Blue Grotto is the symbol of Capri. It is a sea cave found on the coast of the island and is a well-known spot to all who visit the area. This cave is unique for its brilliant blue light which comes from two sources: the entrance to the cave and a bigger hole beneath the entrance. When viewed from inside the cave, the entrance appears as a brilliant white light just above the waterline, while the underwater hole, which is the larger source of light, provides a blue light.
Fifty years ago I had a young family of three boys. My husband Johnny and I left them with a friend while we made a rare trip to the cinema in Liverpool.
It was dark and pouring with rain but with
the headlights shining on the road 
we saw something ahead of us. Johnny pulled to a stop and I jumped out, ran to the grass edge and grabbed a small, wet, and frightened creature. I wrapped it safely in my woollen hat and insisted that my husband turn back and head for home. We thought it was a baby rabbit because it had long ears and was grayish-brown in colour. Once home, we filled a box with torn-up newspaper and a warm towel. We named our new animal Bobsy as we had no idea of its sex.
Sadly though, on the third day with us, it caught its back foot in a door and we quickly realised it was broken. We rushed to the vet (兽医), who said, "It's only a rabbit, I'll put it to sleep." Our response was a very determined, "No way !"We found another vet and told that she was a baby hare. We were told we should continue to keep her in her box for a week and her foot would heal.
After her recovery, Bobsy learnt to use the kitty litter tray. She would comb her long ears with her front paws. The local paper heard about this and came to our house to take her photo and write a story about her. We had her for seven wonderful years before we moved to New Zealand and we will never forget her.
Scientists in Western Australia claim to have made a new discovery—they have found gold in the leaves and twigs of trees. The researchers believe that the trees suck up the gold from deep underground, over 30 metres down. The discovery has been described as the first of its kind in the world. Australian gold exploration companies are pleased because it will make finding gold cheaper. Rather than drilling deep holes to find gold, they have more ways to examine tree leaves and branches. There is only a tiny amount of gold in the leaves. It would take 500 trees to make one gold ring. The gold is found using a special X-ray machine owned by an Australian government agency. A pure X-ray and a powerful microscope scan the leaves and branches.
The claim that this is the first time that gold particles (微粒) have been found in living material might not be true, though. Ancient Chinese wisdom understood the connection between plants and the precious stones and minerals underneath them. They used plant life to find minerals and that was thousands of years ago. In the Zhou Dynasty, it was written in a book that a certain plant grew only near deposits of gold. Over the next 2,000 years, Chinese people wrote about different plants and how they grew, showed where minerals and precious stones such as jade, copper, lead, silver and gold were.
Even more importantly, in the 1, 000s, Su Song described how copper, gold, silver, lead and tin were observed and taken from certain plants. These were amazing scientific discoveries. Meanwhile, this knowledge was unknown in the rest of the world until about 1, 600. This was when a British man realised that oak trees grew larger and greener where there was alum (明矾) in the ground. Maybe ancient Chinese has more knowledge to teach modern scientists.
There's a world of difference between a horror movie and a comedy—the former scares you half to death while the latter leaves you rolling on the floor with laughter. But try watching them without the background music and you just might decide they're not so different after all. Music and movies have been closely connected since the beginning of the film industry—even before the voices of actors were recorded. In movies, music helps to provide a sense of time and place, convey ideas about the characters and, most importantly, draw emotions out of the audience.
Studies have long shown that our heart rates and anxiety levels rise and fall depending on the speed of the music we hear. Using this knowledge, composers use sudden changes in film music speed to create fear among audiences. Slowing the speed of the music will have the opposite effect, bringing about a sense of peace or a dreamlike quality. The use of dissonant (不和谐的) tones and noises is another technique that heightens tension. Humans naturally become unnerved when we hear dissonant sounds because such noises are usually associated with danger, like those that animals make to warn against predators (捕食者).
As crucial as it is, the best film music is subtle. All that audiences are supposed to feel is a heightened sense of emotion—they shouldn't realize what's causing it. Only when the music is taken out of the film should audiences understand its effects.
In keeping with this principle, some filmmakers are even using what's called "infrasound" (次声波) to arouse fear. While we may not be able to hear it because its frequency is below the range of the human ear, infrasound has been proven to cause anxiety, tremble and even sorrow. For example, infrasound was used in the soundtrack of the 2007 horror movie Paranormal Activity, and audiences reposed extremely high fear levels despite the 1ack of action throughout the movie. "It doesn't affect everyone equally," said British science writer Philip Ball, author of The Music Instinct, but he predicted that "we will see more of it used in movies in the future".

The man who could see the future
The ability to predict the future is a rare talent. American author Isaac Asimov (1920-1992), one of the great science fiction writers of his age, had such a talent. Now that we're here, let's see what he got right.
Asimov thought computers would cause a revolution comparable to the industrial revolution of the 19th century. Specifically, he said that "mobile computerized objects" would be an important part of everyday life. Here, he clearly predicted our world of smartphones, tables and other devices. He also had a great deal to say about space exploration.
How did Asimov develop his special sense of future developments? He read the newspapers and magazines sold in his parents' candy store. His scientific interest gained sharper focus at Columbia University in New York. Asimov went to study chemistry, but became bored with pure laboratory science. Instead, he thought hard about the social implications (作用) of science. He wanted to communicate his ideas to the public.
Asimov had his finger on the pulse (脉搏) of both scientific and social change. He had a clear vision of what was coming around the corner for humanity in his works like the Galactic Empire series (《银河帝国系列》). "His predictions are absolutely fascinating," Calum Chase, an English writer, told BBC News. "He was a genius."
Axel Winch was born nearly 13 weeks prematurely (早产地). He 1 2 pounds, 12 ounces and had bleeding in his brain, vision and hearing 2. After a week in the 3 in Grand Junction, where parents Melissa and Adam Winch live, he 4 a life-threatening intestinal (肠道的) condition. Doctors 5 to airlift (空运) Axel and Melissa more than 200 miles to Children's Hospital in Aurora.
His health remained 6 over the next few weeks as his lungs shut down. "There were many times we didn't think he was going to 7." Adam said. 8, support was on the way. Melissa, 39, is a police officer. The police department in Grand Junction 9 officers in Aurora. Soon, members of the Aurora police department 10 the hospital with offers of help. One brought them banana bread. A detective gave the 11 a place to stay.
But then things got 12 again. After weeks of caring for Axel in Aurora, the couple had to briefly return to Grand Junction on two separate 13. First, their house had been under contract and they had to 14 in two days. The second time, Melissa's 15 had run out, so she had to return to work for a few days. They hated having to abandon their son, who had improved but was still facing 16 surgeries.
"We were afraid he was going to die while we were gone," Adam says. Aurora police Mike set up a 17 for his officers to spend time with Axel—when his 18 couldn't he there. They 19 the parents photos of themselves asleep with Axel and updates from the nurses. After four months in the hospital, Axel was 20 enough to go home.
The State Hermitage Museum in St. Petersburg, is second-largest art museum in the world after the Louvre, France, both of which are visited by millions of people (annual). Hermitage holds not only artistic treasures but also a collection of living history well.
The Hermitage was built as part of the royal Russian family's Winter Palace. Empress Elizabeth had cats brought in (rid) the several palace buildings of mice. The cats did their job well and (give) homes in the basements of the buildings and the title of Hermitage cats.
The 74 Hermitage cats live at the museum they now lead an extremely (comfort) life. A press secretary is in charge of the cats, with three full-time caretakers (attend) to their every need. There are even kitchens for preparing meals for the cats because every cat has its own (prefer). This may all seem over the top, but Russian and foreign (visit) alike love seeing the Hermitage cats while admiring some of the world's greatest artistic treasures.

To be a volunteer is a great pleasure. Last Sunday, I get up early because I was so excited to sleep any longer. In morning, we arrived at the Happing Nursing Home. How happily the old people were when they saw us! Then we cleaned the windows or swept the floor for them, some of us gave some performances to them, such as sing songs and dancing. When it was time for us volunteers to leave, we were grateful for our kindness. From this meaningful activity, I have realized that we are supposing to care for the old. In our daily life, we should offer our seat to them on buses and treat our own grandparents more kindly. I sincerely hope more people will join in us.
