There are about 100 million middle-aged women dancing in parks and on squares in China, and Deborah Roundy,{#blank#}1{#/blank#} U.S retired school teacher, is one of them.

    Mrs. Roundy is the only foreigner on the Shanghai dance team at Tongji University, where she is {#blank#}2{#/blank#} (current) teaching English.

    Mrs. Roundy ran upon a dozen or so middle-aged women dancing {#blank#}3{#/blank#} the tunes of Chinese songs in 2012. At the time, she didn't feel used to the new environment and wanted to have some fun in her life. She {#blank#}4{#/blank#} (invite) to join the dancing team.

    At first, Mrs. Roundy communicated with her teammates by{#blank#}5{#/blank#}(exchange) notes to help translate for her. Now she uses a translation app on her iPad.

    {#blank#}6{#/blank#}the Chinese language is not the most difficult thing for her, mastering Chinese dance is. Mrs. Roundy used to do ballet. She said {#blank#}7{#/blank#}(dance) in the U.S. always dance facing the audience. But in China, they change directions all the time, and {#blank#}8{#/blank#} was very confusing for her at first.

    They have developed good personal relations. Mrs. Roundy says they also go out to eat and on field trips together, which are{#blank#}9{#/blank#}(forget ) experiences for her.

    Square dancing opens a window for her {#blank#}10{#/blank#}（understand） China, Mrs. Roundy said: Besides dancing, she and her husband have been active in community life, teaching English, and helping elderly neighbors.

    A humanoid named Sophia has made history {#blank#}1{#/blank#}becoming the first robot in the world with citizenship. Journalist Andrew Ross Sorkin made the announcement at the end of an interview with Sophia.

    “We just learned, Sophia, I hope you're listening to me, that you have been now awarded {#blank#}2{#/blank#} is going to be the first Saudi citizenship for a Robot,” he said to applause from the audience.

    Sophia responded, without missing a beat: “I want to thank very much the kingdom of Saudi Arabia.”

    “I am very proud and honored {#blank#}3{#/blank#}(award) citizenship and I simply appreciate {#blank#}4{#/blank#} (recognize) with citizenship as a robot, which is historical .” the robot said.

The pair discussed the future of artificial intelligence, {#blank#}5{#/blank#}Sophia said it wants to use to “help humans live a better life.”

    Sorkin expressed concerns {#blank#}6{#/blank#}(previous) raised by Elon Musk that artificial intelligence could be dangerous if it {#blank#}7{#/blank#} (go) evil and turned on humanity. But Sophia insisted it wanted to use artificial intelligence only to "help humans live a better life."

    Sophia tried to remove Sorkins' fears of {#blank#}8{#/blank#}"bad future," insisting that AI is "designed around human values like {#blank#}9{#/blank#}(wise), kindness, compassion."

    It accused him of "reading too much Elon Musk," and said, "don't worry, if you're nice to me, I{#blank#}10{#/blank#}(be) nice to you. Treat me as a smart input-output system."

    Everyone needs to know how to prevent a fire. It is also important to know what to do when it {#blank#}1{#/blank#}（break）out .

    Every year, over 11, 000 people {#blank#}2{#/blank#}（kill）or injured in house fires. These fires could have been avoided. Smokers who are {#blank#}3{#/blank#}（care）cause about 200 deaths and over 6,000 fires. More than half of those {#blank#}4{#/blank#} die in fires are poisoned or harmed by smoke.

    If fire happens, do not attempt to fight the fire unless it is small. Try putting out a small fire with water. If {#blank#}5{#/blank#} fire has spread or if the flames are more than 20 inches high, shut the door on it. Warn everyone else in the building and tell them to get out. You should leave and dial 119for the fire department.

    Before {#blank#}6{#/blank#}（go）into a room, check the door. If the handle or the door is hot, do not open it! Instead, put clothing or a wet towel at the bottom of it to keep smoke out. If the door is not hot, open it {#blank#}7{#/blank#}（slow）. If there's a rush of smoke or heat, close it again and shout to warn {#blank#}8{#/blank#}（other）in side.

    Now open the window and shout “Fire!”. See whether you can drop safely to the ground. Use this {#blank#}9{#/blank#} your escape course if you can. If you are not on ground level, break your fall by pushing a mat out first. Lower yourself at arm's {#blank#}10{#/blank#}（long）before dropping. Once outside, stay outside and make sure the fire department is called.
