      Chengdu has dozens of new millionaires, Asia's biggest building, and fancy new hotels. But for tourists like me, pandas are its top{#blank#}1{#/blank#}(attract).

     So it was a great honour to be invited backstage at the not-for-profit Panda Base, where ticket money helps pay for research, I{#blank#}2{#/blank#}（allow）to get up close to these cute animals at the 600-acre centre. From tomorrow, I will be their UK ambassador. The title will be {#blank#}3{#/blank#}(official) given to me at a ceremony in London. But my connection with pandas goes back {#blank#}4{#/blank#}my days on a TV show in the mid-1980s, {#blank#}5{#/blank#} I was the first Western TV reporter{#blank#}6{#/blank#}(permit) to film a special unit caring for pandas rescued from starvation in the wild. My ambassadorial duties will include {#blank#}7{#/blank#}(introduce) British visitors to the 120-plus pandas at Chengdu and others at a research in the misty mountains of Bifengxia.

     On my recent visit, I help a lively three-month-old twin that had been rejected by

{#blank#}8{#/blank#}(it) mother. The nursery team switches him every few{#blank#}9{#/blank#}( day) with his sister so that while one is being bottle-fed,{#blank#}10{#/blank#} other is with mum—she never suspects.

    When I was a university student, I {#blank#}1{#/blank#}(attract) by the Chinese. So I got a job as a teacher in Wuhan three years ago.{#blank#}2{#/blank#} (think) back, I realize it was the students I met in the first year and Chinese university life in general {#blank#}3{#/blank#}gave me the deepest impression.

    During my school days, I would rarely give up my spare time to any activity {#blank#}4{#/blank#}(connect) with study. Unless exams were approaching, my weekends were devoted to having fun or perhaps a part-time job. My Chinese students,{#blank#}5{#/blank#} the other hand, seemed to spend their entire waking hours studying. I understand that competition in Chinese universities is extremely fierce. Nonetheless, their energy and motivation put {#blank#}6{#/blank#}(I) to shame.

    My first year in China was also my first year as a teacher. It was both challenging {#blank#}7{#/blank#}rewarding. One thing I know for certain is that my year in Wuhan changed me for the {#blank#}8{#/blank#}(good). Thanks to the politeness and {#blank#}9{#/blank#}(warm) of Chinese students, I overcame my fear of speaking in public and became more self-confident. Most {#blank#}10{#/blank#}(important), I met dozens of nice people and made many excellent friends.

    In much of Asia, especially the so-called “rice bowl” cultures of China, Japan, Singapore, Korea, {#blank#}1{#/blank#} Vietnam, food is usually eaten with chopsticks.

    Chopsticks are usually two long, thin pieces of wood or bamboo. They can also be made of plastic, animal bone or metal. Sometimes chopsticks are quite artistic. Truly elegant chopsticks might {#blank#}2{#/blank#} (make) of gold and silver with Chinese characters. Skilled workers also combine（使……结合）different kinds of hardwoods and metal {#blank#}3{#/blank#} (create) special designs.

    The Chinese have used chopsticks for five thousand years. People probably cooked their food in large pots, {#blank#}4{#/blank#} (use) twigs（树枝）to remove it. Over time, {#blank#}5{#/blank#} the population grew, people began cutting food into small pieces so it would cook more quickly. Food in small pieces could be eaten easily with twigs which {#blank#}6{#/blank#} (gradual) turned into chopsticks.

    Some people think that the great Chinese scholar Confucius, {#blank#}7{#/blank#} lived from roughly 551 to 479 B.C., influenced（影响）the {#blank#}8{#/blank#} (develop) of chopsticks. Confucius believed knives would remind people of killing and {#blank#}9{#/blank#} (be) too violent for use at the table.

    Chopsticks are not used everywhere in Asia. In India, for example, most people traditionally eat {#blank#}10{#/blank#} their hands.

    One night, a mother and her daughter went out for dinner together. The mother was a heavy smoker, {#blank#}1{#/blank#}(make) her daughter feel very upset and worried. She would often tell her mother that smoking was very bad {#blank#}2{#/blank#}her health. But her mother wouldn't listen and refused to stop smoking.

    However, at {#blank#}3{#/blank#}(they) dinner that night, she noticed that her mother didn't have a single cigarette. As a matter of fact, she realized that she hadn't seen her mother smoke for {#blank#}4{#/blank#} whole day.

    “I can see that you're not smoking at all today. Are you trying {#blank#}5{#/blank#}(give) up smoking?” the daughter asked hopefully.

    The mother answered, “No, I'm just feeling a little bit sick right now. I don't smoke {#blank#}6{#/blank#}(cigarette) when I'm sick, because if I do, it takes me {#blank#}7{#/blank#}(long) to get better.”

    The daughter{#blank#}8{#/blank#}(reply), “Well, I guess you would{#blank#}9{#/blank#}(probable) live a better life {#blank#}10{#/blank#}you got sick a bit more often!”

    Cao Yuan, a 22-year-old Chinese doctoral student in physics, was on top of {#blank#}1{#/blank#} most important scientists named by the journal Nature in 2018 for {#blank#}2{#/blank#} (discover) a "magic angle" in graphene (石墨烯).

    Cao's discovery takes a huge step in the decades-long search for superconductors (超导体) in the world. Why was Cao able to make the discovery? His teachers think it is Cao's independent learning ability and interest in doing experiments {#blank#}3{#/blank#} matter. His high school physics teacher said Cao had a strong ability to study on {#blank#}4{#/blank#} (he) own and was brave to challenge teachers and ask difficult questions. "Cao is {#blank#}5{#/blank#} (deep) curious about laboratory equipment," his college teacher told Nature. "Every time I go into Cao's office, it's {#blank#}6{#/blank#} a huge mess, with computers {#blank#}7{#/blank#} (pull) apart and pieces of telescope all over his desk."

    At 14 he {#blank#}8{#/blank#} (admit) into the University of Science and Technology of China's School of the Gifted Young, a special school to cultivate {#blank#}9{#/blank#} (teenager) into world-class talents. But Cao doesn't think himself special and often stresses that he is just an ordinary kid who {#blank#}10{#/blank#} (love) reading about science and doing experiments. "After all, we are all humans, with shortcomings and emotions," he once said.
