Machu Picchu is an unusual site in Peru and one of the most mysterious wonders of the world. Built at almost 10,000 feet on the top of an Andean mountain, the Incas built hundreds of structures made of stone. A large number of Machu Picchu's surrounding structures date back to the early 13th century, but it was considered a chief sacred site far before then. The Inca people changed the large site into a very small but wonderful city, completely self-sufficient and hidden from below. Agricultural terraces (梯田) surrounded the entire city, fed by natural spring water, supporting the entire population.

Inca Trail

    The trail is one of the most famous in the world and regarded as one of the best. It covers only 26 miles, combining cloud forest, green mountain scenery, forest, and plenty of tunnels, paving stones, and ruins. The four-day hike begins slowly but quickly changes into a difficult journey suitable for those in excellent shape. The trail winds through the Andes, leading alongside and through ruins. Though independent hiking was once permitted, now it must be done with a guide.

Funerary Rock

    It is believed that the Funerary Rock at Machu Picchu was used as a place to prepare Inca nobles for preservation, or mummifying (做成木乃伊), a common habit among the tribe. Nobles would be laid out to be mummified by the hot sun and freezing cold nights after their organs were removed. The rock is also famous as a spot from which a view of the city is afforded.

Temple of the Sun

    Within the city's castle, deep within Machu Picchu, is the Temple of the Sun, accessed only by the Emperor and

    Inca priests. It means the Inca's advanced knowledge of religion, weather, and nature, showing the great extent

    Incas went to adapt to and learn about nature. Still unbroken, the temple was built to honor the god Inti, who is exactly the sun. The temple was effectively protected. It was also a very important scientific center, built in half-moon shape with openings facing north and east. The windows' shadows in the center of the temple helped see the start of winter solstice (至日), showing farming season.

    NEW YORK—Australian mining enterpriser Clive Palmer on Tuesday unveiled(公布) blueprints (蓝本) for Titanic Ⅱ, a modern copy of the doomed ocean liner, although he didn't call the ship unsinkable any more.

    The ship will largely recreate the design and decoration of the fabled original, with some modifications to keep it in line with current safety rules and shipbuilding practices, and the addition of some modern comforts such as air conditioning, Palmer said at a press conference in New York.

    The three passenger classes, however, will be prevented from mingling(混杂), as in 1912, Palmer said. “I'm not too superstitious(迷信的). ”Palmer said when asked whether recreating a ship best-known for sinking was tempting fate.

    White Star Line, the operator of the original ship, had said the Titanic was designed to be unsinkable. About 1, 500 people died on Titanic's maiden voyage in 1912 from Southampton to New York after the ship collided with an iceberg in the North Atlantic.

    Palmer, who created the company Blue Star Line last year, refused to make a similar boast.

    “Anything will sink if you put a hole in it,”Palmer said. “I think it would be very cavalier(漫不经心的) to say it.”

    Unlike the original, TitanicⅡ will have more than enough space in its lifeboats for every person on board and will have additional escape staircases. Markku Kanerva, sales director at Deltamarin, the Finnish company designing the ship, said it would be “the safest cruise ship in the world”.

    Palmer refused to answer questions about the project's cost. Although the Titanic was the world's largest ship in her time, she would be smaller than many of today's modern cruise ships.

    “It's not about the money, ”Palmer said. “I've got enough money for it. I think that's all that matters.”

    Forbes estimated Palmer's net worth to be $795 million in 2012. He describes himself as a billionaire.

    TitanicⅡ will be built by Chinese state-owned CSC Jinling Shipyard, which has already built four ore carriers for Palmer's mining business, he said. The contract to build TitanicⅡ has not yet been signed, Palmer said.

    There is a very long list of rules for the New York City subway. Don't put your feet on a seat, don't carry open cups of coffee or soda, don't take more than one seat... Those are just a few of the rules. There are hundreds more.

    With so many rules, why is it still unpleasant to ride the subway?

    Some people think that the problem is that no one enforces the rules. Other passengers sometimes try to enforce rules. But you can't rely on them because New Yorkers have unwritten rules against talking to strangers and making eye contact with strangers. How can you tell someone to take her shopping bags off the seat and throw away her Coke without talking to her or looking at her? It is difficult.

    There are other New Yorkers who think that the subway is unpleasant because there are not enough rules. One rider wrote a letter to The New York Times a couple of weeks ago suggesting a few more subway rules. Here are some of the rules that she would like to see:

    —Don't lean on the poles. You prevent other people from holding on. They can fall down.

    —Talk quietly. The trains are already too noisy.

    —Give your seat to elderly passengers or to parents with small children.

    If those unwritten rules of etiquette are written down, will the rude people be more likely to follow them? It doesn't make sense to make more rules that no one will enforce.

    The real problem is that we are forgetting how to be nice to each other. It is embarrassing that we need a rule to tell us to give our seat to elderly passengers. Nobody should need to be reminded to do that.

    I say we stop talking about the rules and try to remember our manners. Let's be nice to each other not because a police officer might tell us to get off the train, but because it is the right thing to do. Then New York City would be more civilized —both above ground and below.

For Adam Johnson, a potter from Brighton, the interest stirs (萌动) each spring. "It grabs a hold of me," he said. "I just get the desire to dig." Together with his shovel (铲), he is part of a larger movement. Around the world people are discovering the joys of an ancient practice: the digging of holes. TikTok videos of people digging purely for fun have been viewed millions of times. Instagram accounts devoted to the pastime have many followings.

Charlie Mone, a student at St Andrews University, was changed while digging on the beach in Gran Canaria last year. When he returned home, he founded the university's first hole-digging society. "I didn't think it would go anywhere," he said. Dozens of diggers regularly attend its events on East Sands Beach on the east coast of Scotland and the society's Facebook page has more than 300 followers.

Mone believes that that much of the appeal lies in the friendship working on a shared project in the sea air. "It's struck a chord (共鸣) with people," he said. "There's something therapeutic to just switching your brain off and digging a hole." At the end of each 1 session, the holes are filled in to prevent accidents.

Back in Brighton, Johnson, 38, is more of a lonely digger. "I have often started digging without an actual plan," he said. "Once I took out an unruly bramble (荆棘) and found some rock so I dug that out, then carried on a bit until I was in a good general digging rhythm. A few hours later my partner asked if I was coming in for dinner-the bramble had come out at breakfast and I found myself in a six-foot hole. The hole would become a sunken hot tub, but the digging would have been worthwhile anyway, he suggests. "There's something basic about it. And you find all kinds of buried treasure from people who had the garden before you. There's something magical about digging."
