Last Friday, my friend David called me and invited me and our friend Tom to a party in his university. Tom and I are in{#blank#}1{#/blank#} same class. We both wanted to go to the party, but there was a problem—we'd have a final exam on the {#blank#}2{#/blank#} (come) Monday.

    “Don't worry. We can come back on Sunday and won't miss the exam,” really{#blank#}3{#/blank#} (want) to go to the party, Tom said. So I decided to go{#blank#}4{#/blank#} him.

      The party was great and we{#blank#}5{#/blank#}  (true) enjoyed ourselves there. However, we stayed up late on Saturday night and slept all day on Sunday and didn't make it back to our university until Monday morning. We missed the exam. Then we went to our professor's office and explained{#blank#}6{#/blank#} we missed the exam. We lied that there was a flat tire（车胎漏气）on our way back to the university. Our professor {#blank#}7{#/blank#} (agree) that we could take the exam the following day.

    When it was time to take the exam, Tom and I{#blank#}8{#/blank#} (take )to different rooms. After we opened the test paper, we saw only one question, “Which tire?”

    Neither Tom nor I answered the question. Instead we told our professor the truth. Luckily, he later gave{#blank#}9{#/blank#} (we) the real test paper . And both Tom and I made a{#blank#}10{#/blank#} (decide): never to lie again.

    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.

    A computer program has beaten a human player at the ancient Chinese board game Go（围棋）. It marked an important advance for the {#blank#}1{#/blank#} (develop) of artificial intelligence. The program, {#blank#}2{#/blank#} (call) Alpha Go, had taught itself how to win. It beat the European player in all five games of a match in October. The developers say {#blank#}3{#/blank#} (it) learning ability may someday let computers help solve real world problems. Those could include making medical diagnoses and {#blank#}4{#/blank#} (explore) scientific research.

    Previous computers have beaten humans in other games. But among classic games, Go has long been viewed as the most challenging game for artificial intelligence to master. Therefore, many people find it {#blank#}5{#/blank#}(accept) when AlphaGo won the human player.

    Go involves two players who take turns putting markers on a checkerboard-like grid (格子).  Players obtain the opponent's pieces {#blank#}6{#/blank#} surrounding them. The rules are simple, {#blank#}7{#/blank#} playing it is not. It's {#blank#}8{#/blank#} (probable) the most complex game ever created by humans.

    Martin Mueller, a computing science professor, {#blank#}9{#/blank#} (work) on Go programs for 30 years. He once said, "The new program is really a big step up from everything else that we've seen. It's a very {#blank#}10{#/blank#} (amaze) piece of work."

It was raining lightly when I {#blank#}1{#/blank#}(arrive) in Yangshuo just before dawn. But I didn't care. A few hours {#blank#}2{#/blank#}, I'd been at home in Hong Kong, with {#blank#}3{#/blank#}(it) choking smog. Here, the air was clean and fresh, even with the rain.

I'd skipped nearby Guilin, a dream place for tourists seeking the limestone mountain tops and dark waters of the Li River {#blank#}4{#/blank#} are pictured by artists in so many Chinese {#blank#}5{#/blank#}(painting). Instead, I'd head straight for Yangshuo. For those who fly to Guilin, it's only an hour away {#blank#}6{#/blank#} car and offers all the scenery of the better-known city.

Yangshuo {#blank#}7{#/blank#}(be) really beautiful. A study of travelers {#blank#}8{#/blank#}(conduct) by the website TripAdvisor names Yangshuo as one of the top 10 destinations in the world. And the town is fast becoming a popular weekend destination for people in Asia. Abercrombie & Kent, a travel company in Hong Kong, says it {#blank#}9{#/blank#}(regular) arranges quick getaways here for people {#blank#}10{#/blank#}(live) in Shanghai and Hong Kong.
