Anyone who has had a long-term disease knows that recovering at home can be lonely. This can be{#blank#}1{#/blank#}(especial) true of children. They may feel {#blank#}2{#/blank#} (leave) out. Now, these children may have a high-tech friend to help fed less alone. A small robot may help children who are recovering from long-term illnesses. The robot like human beings takes their place at school. And their school friends must help carry the robot between classes and place the robot on their desks.

    Through the robot, a child can hear his or her teachers and friends. He or she can also attend classes from wherever they are recovering—whether at home{#blank#}3{#/blank#}from a hospital bed. Dolva, one of the scientists who {#blank#}4{#/blank#}(be) concentrating on developing the robot, explains{#blank#}5{#/blank#}the robot AVI works. She says from home, the child uses a tablet or phone to start the robot,{#blank#}6{#/blank#} (use) the same device, he or she can control the robot's movements. Inside the robots there is a small computer linked{#blank#}7{#/blank#}a 4G network. The robot is {#blank#}8{#/blank#}(equip) with speakers, microphones and cameras,{#blank#}9{#/blank#}makes communicating{#blank#}10{#/blank#}(easy). So it's the eyes and the cars and the voices at school. Hopefully AVI will help some children feel less lonely while they are absent from class.

    Recently a really strange thing happened in a middle school in China's Hubei Province. Over 600 students there took part in a “caring for an egg like a baby”{#blank#}1{#/blank#} (active) in which they were asked to keep an egg close at hand for a month{#blank#}2{#/blank#}breaking it.

    "It's hard for parents to bring up their children{#blank#}3{#/blank#}many students just ignore it,” said Liu Kang, the school's director. "They should{#blank#}4{#/blank#}(teach) to be grateful to their parents, who have given them life but ask for nothing in return.”

    Li Ming is one of the students. His egg didn't break during the month, but he felt{#blank#}5{#/blank#}(exhaust). "I now realize that my parents have had great difficulty{#blank#}6{#/blank#}(bring) me up. I'll do all I can to make their life easier and more{#blank#}7{#/blank#}(comfort) when I grow up.” promised the 13-year-old boy.{#blank#}8{#/blank#} (luck), about 10 students broke their eggs. Yan Yueming broke his egg after just five days, which made him frustrated. He said, "I can't imagine{#blank#}9{#/blank#}sad my parents would be if there was something wrong with me, their 'egg'!" It is time I{#blank#}10{#/blank#}(do) something in return for their love.” said Yan.

    Some theme parks are not only amusing but also educational. Take the Polynesian Cultural Center (PCC) in Hawaii for example. It not only shows visitors the Polynesian way of life but also protects their skills{#blank#}1{#/blank#}culture for the future. Polynesian is the name{#blank#}2{#/blank#}(give) to the many groups of small islands that are spread about the Pacific Ocean.

    The PCC{#blank#}3{#/blank#}(set) in 42 acres of beautiful countryside{#blank#}4{#/blank#}visitors can see seven different traditional Polynesian island villages. Villagers from many island communities come{#blank#}5{#/blank#}(show) visitors their styles of dress and different customs. For example, you can see{#blank#}6{#/blank#}(difference) skills of the villagers. You can learn{#blank#}7{#/blank#}they make clothes from bark(树皮) and how they climb very tall trees {#blank#}8{#/blank#}their bare feet or see{#blank#}9{#/blank#}kind of wedding ceremonies they have. They also tell you about their{#blank#}10{#/blank#}(society) customs and show you their cooking methods and their dances.

    Mac was cycling along a road. With a heavy camp bag, he wasn't moving very fast. Suddenly he heard loud breathing behind him. {#blank#}1{#/blank#} (look) to his side, he was {#blank#}2{#/blank#} (terrify) to find it wasn't a dog but a wolf that was running after him. He reached {#blank#}3{#/blank#} the spray in the bag. With one hand on the handlebar, he fired it. A bright red color covered the wolf and it fell back shaking its head. But a minute {#blank#}4{#/blank#}(late) it was by his side again. He sprayed {#blank#}5{#/blank#} second time, the wolf falling back again but only to quickly restart {#blank#}6{#/blank#} (it) attack. The wolf was getting closer. Mac waved and yelled at passing {#blank#}7{#/blank#}(motorist) but meanwhile rode hard. He knew clearly he must be careful not to slow down. {#blank#}8{#/blank#}(fortunate) , Paul and Becky were driving along the same road when they spotted the scene. They drove toward Mac. When the car was in front of him, Mac jumped off the bike and dashed for the back door. Paul {#blank#}9{#/blank#}(open) the door so as to let Mac in. It was quite a while {#blank#}10{#/blank#} Mac became calm and thanked them.

    In the 1980s, Paolo Dario dreamed of developing {#blank#}1{#/blank#}(high) advanced artificial limbs(假肢) to help people who really need such devices(设备), but he never expected his dream to be realized. Dario, {#blank#}2{#/blank#}professor of biomedical robotics in Italy, said that as an engineer he always wants to see such dreams come true, even if a lot of work must {#blank#}3{#/blank#} (do).

    He {#blank#}4{#/blank#}(make) the comment(评论) in Beijing last month during a keynote speech at the 2019 World Robot Conference." You have to understand the {#blank#}5{#/blank#}(exist) problem and develop robotic arms by thinking outside the box. We hope what we need for robots can become smaller and lighter. But at the same time, as a lot of technology is now used in robotic sensors (传感器), they have become much {#blank#}6{#/blank#}(large)," he said.

    A paper {#blank#}7{#/blank#}was published in the journal Nature in 2014 stated that a human can not only control artificial limbs, {#blank#}8{#/blank#}feel the different materials they are made from as well." In the future, the super robot will further enable people with disabilities to walk on {#blank#}9{#/blank#}(they) own and allow blind people {#blank#}10{#/blank#}(recover) their sight," Dario said.
