    The ancient city of Xi'an in China holds many treasures. And last month, archaeologists working there made an important discovery—a buried palace built in the third century B.C. to honor China's first emperor.

    The entire palace measures roughly 2,260 feet long by 820 feet wide. It includes 10 courtyard houses and one main building. Archaeologists found bricks and pieces of pottery at the site of the palace, as well as the remains of walls and roads.

    The palace is part of the massive burial complex of Emperor Qin Shihuangdi. He conquered seven warring kingdoms and united ancient China in 211 B.C.

    Qin Shihuangdi wanted his legacy, or accomplishments, to be remembered forever. So he hired more than 700,000 workers to build his funeral complex in Xi'an. It represents a miniature version of his vast kingdom.

    The complex also includes the world-famous terra-cotta army, a collection of more than 8,000 life-size clay statues. These sculptures represent soldiers, acrobats, and horses from the Qin Dynasty (221 B.C.-206 B.C.). Scientists have not yet found all these terra-cotta warriors, even though they discovered more of the statues last summer.

    Farmers discovered the complex by accident in 1974. Since then, scientists studying the site have learned a great deal about life in ancient China. But much of the emperor's tomb has yet to be dug up, or unearthed. Many of the artifacts (objects from the past) are so old that scientists cannot preserve them.

    "Archaeologists fully acknowledge that nobody in the world has the technology (to safely dig up Xi'an's treasures) yet," explains Kristin Romey, an expert on Chinese archaeology.

    But as technology improves, archaeologists will keep digging to uncover the rest of the wonders that still lie buried in Xi'an.

    "It's one of the most important archaeological discoveries that's waiting to be made," says Romey, "and we know where it is."

    Today's post is almost about signs in English. You will see signs on the road while driving or when walking down a street. Now let's take a closer look at the signs in the picture below, so you can fully understand what they mean in case you come across one of them.

    Starting with the top row, we have a:

    Yield sign—This sign indicates (标示) that you need to slow down ,but you may not have to come to a full stop.

    Crosswalk—This is a sign that indicates people have the right of way to cross the street, so cars have to stop when they see a person waiting next to one of these signs.

    Second row:

    Do not enter—This sign indicates you are not allowed to enter a road at that point.

    Buckle up(系好安全带)!— There are often signs on roads in the United States reminding people that wearing seat belts(安全带) is mandatory (强制的) (seat belt laws differ depending on what state you are in ,but all US states have seat belt laws).

    Third row:

    Be alert (警惕的) for bears—This is another sign that is used to indicate to drivers and pedestrians (行人) that they should be alert for wildlife in the area.

Playground—This is the sign used to alert drivers that there is a playground nearby, so it is a good idea to slow down and watch for children.

    Music is magic! Music speaks louder than words and it is a "language" that the whole world can understand. A piece of music can produce a response in the heart and mind. Like feeling an electrical current or receiving a personal radio signal, music has a spiritual effect on a person. Different kinds of music influence people in different ways.

    I have listened to music all my life. When I was twelve years old, the Beatles came to America and my whole world opened up. Maybe young people today cannot understand the influence of the Beatles when they exploded across America. Their influence changed the way we dressed, looked, acted and spoke, even our culture. The Beatles arrived in America from the UK just three months after the assassination(暗杀) of President John Kennedy, which had put America into a great depression. And the freshness and lively spirit of the Beatles was exactly what the country needed to refresh itself.

    Music links the heart of the hearer with that of the composer. This means that it mixes the spirit of the composer with your spirit when you listen to it. And the music can take your spirit out of your body and transport you into another world. Music has a great way of touching people. Music can make you laugh, cry or shout. It's also a great source of inspiration.

    Try this one day and notice what happens: make yourself a cup of tea, sit on your sofa and play one of your favorite songs. Close your eyes, and soon you'll find yourself creating vivid mental images matching the music that you are listening to.

    Standing desks have become common across Silicon Valley, offering health benefits to those willing to work on their feet. However, due to their high price, they have failed to catch on until now. Recently, Ikea has brought out Bekant convertible(可变换的) standing desk that can become a normal desk at the touch of a button. The $500 adjustable desk can transform from a standard desk to a standing one, and Ikea hopes it could make the standing desk mainstream.

    Experts say that changing from a seated to a standing desk can improve productivity. Similar desks have become a common sight at tech firms such as Google, where some employees have even installed treadmill (跑步机) and bicycle desks.

    The desk is not the first "convertible" on the market. As early as 2013, Stir Kinect brought out an adjustable desk. The $3,890 Stir Kinect desk has a motor to raise and lower itself, changing it into a standing desk or a traditional desk. The desk can even be programmed to move up and down slightly, making it appear to take a gentle breath to remind the user to change their positions. To move between sitting and standing positions, owners simply double tap on the screen. The desk can learn the user's preferences over time and suggest the best seating position.

    The Stir Kinect desk was created by a team of ex-Apple and Disney engineers. It has a built-in touch screen to control and track movement, and can tell users exactly how many calories they burn by standing during their working day. It also has devices containing power points and USB ports for charging phones, to keep cables hidden.

    "Ikea's height-adjustable desk is great for opening up the lower end of the market, " said JP Labrosse, founder and CEO of Stir.

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."
