Swedish businessman Nile Bergqvist is delighted with his new hotel, the world's first igloo(冰屋) hotel.

    {#blank#}1{#/blank#} (build) in a small town, it has been attracting lots of visitors but soon the fun will be over. In two weeks' time，Bergqvst's ice creation {#blank#}2{#/blank#} (be) nothing more than a pool of water. “We don't see it as a big problem,” he says. “We just look forward to {#blank#}3{#/blank#} (replace) it.”

    Bergqvist built his first igloo in 1991 for an art exhibition. It was {#blank#}4{#/blank#} successful that he designed the present one, {#blank#}5{#/blank#} measures roughly 200 square meters. Six workmen spent more than eight weeks —piling 1,000 tons of snow onto a wooden base；when the snow froze, the base {#blank#}6{#/blank#} (remove).

After their stay, all visitors receive a survival certificate recording their success. {#blank#}7{#/blank#} no windows, nowhere to hang clothes and temperatures below 0℃, it may seem more like a survival test {#blank#}8{#/blank#} a relaxing hotel break. “It's great fun,” Bergqvist explains, “as {#blank#}9{#/blank#} as a good start in survival training.''

    The {#blank#}10{#/blank#} (popular)of the igloo is beyond doubt：it is now attracting tourists from all over the world. At least 800 people have stayed at the igloo this season even though there are only 10 rooms.

    William Campbell, Satoshi Omura and Tu Youyou jointly won the 2015 Nobel Prize for medicine{#blank#}1{#/blank#} their work against parasitic diseases (寄生虫病). 85-year-old Tu was awarded this prize for her contribution to{#blank#}2{#/blank#} (reduce) the death rate of malaria (疟疾), minimizing patients' suffering and promoting mankind's health. This is {#blank#}3{#/blank#} science is all about.

    As a matter of fact, Tu has won some attention when she {#blank#}4{#/blank#} (get) the Lasker Award in 2011. But there is no way to compare her popularity back to the attention she is receiving today. As the first Chinese mainland Nobel Prize Winner of natural science award, Tu's winning {#blank#}5{#/blank#} (complete) surprised Chinese people, {#blank#}6{#/blank#} have long been wondering when the first Chinese Nobel Laureate in natural science would appear.

    Tu Youyou is the first Chinese scientist to win a Nobel Prize for work {#blank#}7{#/blank#} (carry) out within China. She has spent 40 years' time on scientific research. Although the Nobel Prize did not come to her until four decades later, it is definitely one of {#blank#}8{#/blank#} most privilege rewards that recognizes Tu's devotion and perseverance in discovering artemisinin (青蒿素). Her record-breaking winning  {#blank#}9{#/blank#} (be) a reminder that science is never about instant success. There is no way to measure how much you spend on scientific research and compare {#blank#}10{#/blank#} with how much reward you get.

    My mother and my brother were taking a trip to Washington, D.C. They came back with the most{#blank#}1{#/blank#}(amaze) story I have ever heard!

    When they passed by New York, their train failed to work{#blank#}2{#/blank#}(proper), the conductors asked everyone to move forward to another train. When everyone{#blank#}3{#/blank#}(seat), my mother realized she didn't have her handbag, in {#blank#}4{#/blank#}was her money, tickets, credit card and license. She rushed to a conductor. “Excuse me, I left my bag on the other train. Can you stop the train?” The conductor replied, “Oh, I'm sorry,{#blank#}5{#/blank#}we cannot let you off.” My mom quickly picked up her cellphone,{#blank#}6{#/blank#}only thing she had, and started calling someone for help but{#blank#}7{#/blank#}vain.

    Luckily, when the train finally stopped in Delaware, a man left the train and handed my mom $ 112. My mother thanked him and felt grateful for his {#blank#}8{#/blank#}(kind). She got the man's address and promised{#blank#}9{#/blank#}(find) a way to pay him back. My mother and my brother finally arrived in Washington, D.C., but did not get to do all the things as{#blank#}10{#/blank#}(plan). They got to take a few like rides, buy souvenirs, and more. They made the best of the worst vacation!

    There was a state {#blank#}1{#/blank#}(call) Zhou in the Chinese history. One day, the king of Zhou asked his officials for advice on {#blank#}2{#/blank#} (deal) with the prisoners of war. An official said, “If you love someone, you{#blank#}3{#/blank#} (suppose) to love even the crows on the roof of his house. The prisoners of war are enemies fighting against us. In my opinion, we'd better{#blank#}4{#/blank#} (kill) them all.”

    But the king didn't agree with him. “I think we should treat the prisoner of war{#blank#}5{#/blank#} (different) by differing them into those who are guilty and those who are not. They guilty ones will be sentenced{#blank#}6{#/blank#} death in order to avoid future disasters.”

    Then another one said, “Your majesty, I think all the prisoners should be set free and sent back home to work in the fields and support themselves by their own labor.{#blank#}7{#/blank#}, you should keep strictly the rules for reward and {#blank#}8{#/blank#} (punish). The people are sure to believe in you{#blank#}9{#/blank#} you govern our country be morals and laws.”

    The king thought the official's proposal was quite reasonable so be accepted and followed it. As {#blank#}10{#/blank#} result, the domestic situation soon settled down and gradually the country became stronger.

    Parents' Day is {#blank#}1{#/blank#} American event for the parents and families. {#blank#}2{#/blank#} (surprising), this event was not even there two decades ago.{#blank#}3{#/blank#} was only in 1994 that this event got officially accepted in the USA.

    It is very hard {#blank#}4{#/blank#} (say) when the idea of Parents' Day actually came into picture. But it can be certainly said that this event is born to honor and appreciate parents {#blank#}5{#/blank#} are responsible for the upbringing of the new generation. Their hard work {#blank#}6{#/blank#} endurance (耐力) open up a new horizon for the humankind.

    As said earlier, Parents' Day {#blank#}7{#/blank#}(get) its acceptance in 1994. President Bill Clinton passed the law for {#blank#}8{#/blank#}(recognize), uplifting, and supporting the role of parents. It was decided that the fourth Sunday of every July would be celebrated as Parents' Day, which is similar {#blank#}9{#/blank#} Mother's Day and Father's Day.

    The tradition {#blank#}10{#/blank#} celebrating Parents' Day is relatively new. But within few years after its acceptance, the event has spread its wings to the whole world. Now the event is widely adopted.
