Each year, thousands of people come to Shaanxi, China, to visit the Terracotta Army, which shows the life of Qin Shi Huang,{#blank#}1{#/blank#}country's first emperor.

    As one of the most famous tourist sights in the world, the Terracotta Army is a form of funerary (葬礼的) art{#blank#}2{#/blank#}(bury) with the First Emperor in 210 to 209 BC. It was designed{#blank#}3{#/blank#}(protect) the emperor in his afterlife.

Since their {#blank#}4{#/blank#}(discover), experts have questioned whether the life-size models of soldiers{#blank#}5{#/blank#}(base) on real warriors (勇士) or whether they came off a production line.

    In October a BBC documentary ( 纪录片) the Greatest Tomb on Earth: Secrets of Ancient China, suggested the inspiration for the Terracotta Warriors may have come{#blank#}6{#/blank#}Ancient Greece, about{#blank#}7{#/blank#}Archaeologist Li Xiuzhen said, "We now have evidence that close contact did exist between the First Emperor's China and the West."

    On the 41st International Museum Day, it was{#blank#}8{#/blank#}(official) announced that new technology has just made{#blank#}9{#/blank#}possible for visitors to be guided. Thanks to an interactive(交互式) 360-degree video, visitors can choose either to view the{#blank#}10{#/blank#}(figure) close-up or from a distance.

    According to a recent study, plants are able to make intelligent decisions. They are a lot{#blank#}1{#/blank#}(smart) than we thought. Scientists have discovered that the pea plant can make decisions on how{#blank#}2{#/blank#} (survive) best, even though it does not have a brain. Researchers grew several pea plants that had their roots {#blank#}3{#/blank#} (separate) between two pots. Each pot contained different amount of nutrients. One pot always had the same amount{#blank#}4{#/blank#}the other pot varied between a lot and a little. The plants turned out to be{#blank#}5{#/blank#} (amaze) consistent（一致的）at turning their roots to the pot with the most nutrients.

    Researcher Alex Kacelnik says the experiment raises a question, not about plants{#blank#}6{#/blank#} about animals and humans. He wonders whether the pea plant is more efficient in using its limited resources about {#blank#}7{#/blank#}(make) decisions than humans. He says, “We have a very wonderful brain, but maybe most of the time we're not using {#blank#}8{#/blank#}” Professor Kacelnik does not think that pea plants are intelligent in the human sense, but that they exhibit complex{#blank#}9{#/blank#} (behave) to efficiently take advantage of natural opportunities. It will be interesting to see how our lives would be different if we{#blank#}10{#/blank#} (adopt) similar strategies.

    People have all turned to sad music to make themselves feel better at some point in their lives, {#blank#}1{#/blank#}why does the music with double or even triple sadness help drag people out of low spirits?

    A new study throws light on what's going on inside people's brains when they match their music to their feelings, and it looks as if sad music can be enjoyable, rather than{#blank#}2{#/blank#}(simple) depressing. Music of this sort can arouse positive memories in people's life , thus {#blank#}3{#/blank#}(lift)their mood.

Psychologist Adrian North from Curtin University in Australia says there{#blank#}4{#/blank#}(existence) two groups of possible explanations for why people enjoy listening to sad music like this—one from social psychology, and the other from cognitive neuroscience(神经学).

    {#blank#}5{#/blank#}terms of social psychology, one idea about this is that people will feel{#blank#}6{#/blank#}(good) about themselves if they focus on someone who's doing even worse. Everything's going to be okay, because this person is having {#blank#}7{#/blank#}even worse day than they are.

    Another idea from social psychology is that people like to listen to the very music{#blank#}8{#/blank#}shows their present life circumstances, because this kind of music makes them feel they are understood. With their emotions{#blank#}9{#/blank#}(share), they definitely get a certain amount of comfort.

    So, the{#blank#}10{#/blank#}(conclude) again—sad music does cheer people up, and it works far better than happy music, in most cases.

    My doorbell rings at 11 am. On the step, I find an elderly Chinese lady holding the hand of a little boy. In her other hand {#blank#}1{#/blank#} (be) a paper bag. She is the little boy's grandmother, and her daughter, Nicole, bought {#blank#}2{#/blank#} house next door last October. Nicole has {#blank#}3{#/blank#} (obvious) told her mother that I am having a heart operation shortly, and the result is that her mother has decided {#blank#}4{#/blank#} (supply) me with meals.

    I know what is inside the paper bag——a bottle of hot soup and a {#blank#}5{#/blank#} (contain) with a meal of rice, vegetables and meat. It's become a daily occurrence.

    Communication {#blank#}6{#/blank#} us is somewhat difficult because she doesn't speak English and all I can say in Chinese is hello. Once, she brought an Ipad as well as the food. She pointed to the screen, {#blank#}7{#/blank#} showed a message from her daughter telling me that her mother wanted to know {#blank#}8{#/blank#} the food was all right for me.

So here we are, two grandmothers, neither of {#blank#}9{#/blank#} (we) able to speak the other's language but communicating one way or another (with some help from technology). The doorbell keeps {#blank#}10{#/blank#} (ring) and there is the familiar brown paper bag, handed smilingly to me.

    Nowadays more and more people like to travel, {#blank#}1{#/blank#} (especial) when vacations come.A great number of people rush out of their homes or companies to {#blank#}2{#/blank#} (travel) spots. They either drive or take a bus, a train, a ship {#blank#}3{#/blank#} so on. Some even ride bikes.

    However, there {#blank#}4{#/blank#} (be) another way of travelling—poorism. People have a tour in {#blank#}5{#/blank#} poorest areas of the worlds Some people may take a one-day poorest tour, and some even pay to stay in very poor neighborhoods {#blank#}6{#/blank#} (experience) the lowest living standards in the worlds Poorism tours take place around the world, and not just in the third world {#blank#}7{#/blank#} (country).You can, for instance, tour New York neighborhoods in the Bronx. Such tours can take people into the heart of poor areas. These tours may awaken people to pay {#blank#}8{#/blank#} (much) attention to long-standing poverty, or the effects of war.

    Some think that tours in the poor areas can raise social care. And the money from the tour can {#blank#}9{#/blank#} (donate) to help the people {#blank#}10{#/blank#} live there.
