Dr.Yuan {#blank#}1{#/blank#} for a way to increase rice harvests without  expanding the area of the fields...Dr. Yuan is now {#blank#}2{#/blank#} his knowledge in India, Vietnam and many other less developed countries to increase their rice harvests...{#blank#}3{#/blank#} to his research, the UN has more tools in the battle to {#blank#}4{#/blank#} the world of hunger.

    He made people laugh at a time {#blank#}5{#/blank#}they felt depressed, so they could feel more {#blank#}6{#/blank#}with their lives...His parents were both music hall {#blank#}7{#/blank#}.

    However, people from places like Spain, Italy or south American countries approach others closely and are more {#blank#}8{#/blank#} to touch them.

    In {#blank#}9{#/blank#} , though, studying international customs can certainly help avoid difficulties in today's world of cultural {#blank#}10{#/blank#} .

    Jack Ma, the chairman and founder of China's e-commerce giant Alibaba Group, took down on Google's artificial intelligence AlphaGo at the Big Data Expo{#blank#}1{#/blank#}(hold) in Guiyang, Guizhou Province, and urged Chinese enterprises not to develop such things{#blank#}2{#/blank#}AlphaGo. Chinese Go player Ke Jie, current world No. 1, has admitted defeats in his three{#blank#}3{#/blank#}(match) against computer program AlphaGo in Wuzhen, Zhejiang Province,{#blank#}4{#/blank#}led to heavy online discussions regarding the future of mankind and AI.

    “Machines must have its own special thinking and must do thins human cannot do,” Ma added,{#blank#}5{#/blank#} (believe) AI should work for humans to do useful things that human are unable to achieve, rather than just spoiling human's fun.

    But speaking for myself, I don't really care. I{#blank#}6{#/blank#}(especial) advised that many fellow enterprises should not develop such things and we can do many other useful things.”

    Ma also explained{#blank#}7{#/blank#}he didn't like AlphaGo: “Go game is{#blank#}8{#/blank#}interesting and fun thing where I can wait for my competitor{#blank#}9{#/blank#}(play) wrong and I can win. But the machine never plays wrong and it can work out the next 300 steps{#blank#}10{#/blank#}you can only think about the next three.”

    I'm Yuan Longping. Look at my sunburnt face and arms and my slim strong body and you will think I'm {#blank#}1{#/blank#} like a farmer than a scientist. In fact I {#blank#}2{#/blank#}(struggle) for the past five decades to help {#blank#}3{#/blank#}(farmer). In 1974, I began to grow a so-called super hybrid rice. This special strain of rice makes {#blank#}4{#/blank#} possible to produce one-third more of the crop in the same fields.

    I was born into a poor farmer's family in 1931. When I was young, I saw many people go hungry often. So I have devoted myself to {#blank#}5{#/blank#}(find) ways to increasing rice harvest without expanding the area of fields since I graduated from Southwest Agriculture College in 1953. Now more than 60% of the rice{#blank#}6{#/blank#}(produce) in China each year is from this hybrid strain. I am circulating this knowledge in India, Vietnam and other less developed countries to increase their harvest. Perhaps you think I am rich. {#blank#}7{#/blank#}(actual) I live a simple life. I care little for money. In my opinion, a person with too much money will have more troubles. I don't want to be famous {#blank#}8{#/blank#} I prefer to have more time to do my research. In my free time I love listening to music, playing mah-jong and reading. I once had a dream, in {#blank#}9{#/blank#} I saw rice plants as tall as sorghum and each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. Now I have another dream-to export my rice so that it can {#blank#}10{#/blank#}(grow) all over the world.

    Mark was walking home from school one day {#blank#}1{#/blank#} he noticed that the boy ahead of him had tripped and {#blank#}2{#/blank#} (drop) all of the books he was carrying. Mark knelt down and helped the boy pick up the scattered {#blank#}3{#/blank#} (article). Since they were going the same way, he helped to carry part of the burden. As they walked, Mark discovered the boy's name was Bill, and {#blank#}4{#/blank#} he loved video games, baseball, history and so on. They arrived at Bill's home first and Mark {#blank#}5{#/blank#} (invite) in for a Coke and to watch some television. The afternoon passed {#blank#}6{#/blank#} (pleasant) with a few laughs and some {#blank#}7{#/blank#} (share) small talks, and then Mark went home. {#blank#}8{#/blank#} continued to see each other around school, had lunch together once or twice, and then both graduated from junior high school. They ended up {#blank#}9{#/blank#} the same high school {#blank#}10{#/blank#} they kept regular contacts over the years.

    Every year, A large number of people go back home for Christmas. Joe's plane landed on time at Heathrow Airport. He had {#blank#}1{#/blank#} (exact)one hour to get out of the airport and go across the centre of the airport and the centre of London to catch his train to Manchester. He hurried through the airport, and then raced {#blank#}2{#/blank#} the taxi sign.

    Unfortunately, at that moment, {#blank#}3{#/blank#} (he)luggage broke and dirty socks, shirts and underwear were all over the airport floor. Joe was so {#blank#}4{#/blank#} (embarrass)that he quickly put everything back into his luggage. {#blank#}5{#/blank#} (push)his way through the crowds of people, he finally made it to the taxi rank. He jumped into the nearest taxi, shouting, “Euston Station, quickly, please!” The taxi set off at such {#blank#}6{#/blank#} high speed that Joe was thrown backward, {#blank#}7{#/blank#} made him hit his head against the glass. The taxi sped on and finally arrived in the city centre, and also the middle of a traffic jam! It would be quicker to walk there. Joe offered {#blank#}8{#/blank#} (pay)the driver, got out of the taxi, and ran along the pavement and past all the shop {#blank#}9{#/blank#} (window). At last, he could see the station opposite.

    He reached the station just as his train was leaving. He {#blank#}10{#/blank#} (get)on the train with seconds to spare. He sighed with relief—he would be home in time for Christmas.

    Traditionally, we usually get a general impression of {#blank#}1{#/blank#} (stranger) by the way they shake hands, talk, or walk. However, in the age of social networking, first impressions are sometimes made {#blank#}2{#/blank#} looking at their profile photos on social platforms like Twitter or WeChat.

    These social images say a lot about our personality, according to a recent study, in {#blank#}3{#/blank#} researchers used a software to analyze the profile photos to find out whether there was a connection between a person's personality and his profile photo.

    The result reveals that open-minded people are more likely {#blank#}4{#/blank#} (pose) with an object in their profile photos. Their {#blank#}5{#/blank#} (excite) faces can tell how much they enjoy their experiences. Meanwhile, neurotic (神经质的) people tend to choose photos of objects rather than selfies to avoid {#blank#}6{#/blank#} (look) too miserable because of the strong social practice against a sad or angry {#blank#}7{#/blank#} (appear) in profile photos.

    Apart from the objects in profile photos, the colors used in them also show {#blank#}8{#/blank#} outgoing the owner is. For example, extroverts (性格外向者) {#blank#}9{#/blank#} (find) to have the most colorful profile images, as they want to emphasize their personality.

    Next time choosing a profile photo, maybe we should ask {#blank#}10{#/blank#} (we) first what kind of image we'd like to convey. After all, a picture is worth a thousand words.
