When a man was walking by some elephants, he suddenly stopped. He was wondering why these huge animals{#blank#}1{#/blank#}by a small rope tied to their front legs. It was {#blank#}2{#/blank#}doubt that the elephants could break the rope at any time, but for some{#blank#}3{#/blank#} they did not.

    He saw a trainer nearby and asked why the animals just{#blank#}4{#/blank#} there and made no effort to get away. “Well，” the trainer said, “when they were very young and much smaller, we used the same rope{#blank#}5{#/blank#} them from running away. At that age, it's enough to hold them.{#blank#}6{#/blank#} they grow up, they all believe that they cannot break the rope. They believe it can still hold{#blank#}7{#/blank#} so they never try to break free.”

    The man was{#blank#}8{#/blank#}.These animals could break free whenever they wanted, but because they believed they couldn't, they were stuck right by the same rope {#blank#}9{#/blank#} caught them at young ages.

    How many of us go through life like the elephants—holding onto the belief that we cannot do something{#blank#}10{#/blank#}because we failed at it once before?

    Failure is a part of learning. If we failed once, it doesn't mean we can never succeed. We should never give up trying when we encounter failures in life.

    This is Tammela School, a primary school in Finland. The students are having a math class with their robot teacher.

    The "teacher" is {#blank#}1{#/blank#} small, blue machine about 25cm high, Reuters reported. Whenever students have problems, it helps them very {#blank#}2{#/blank#} and never gets bored.

    "The robot can make students more {#blank#}3{#/blank#} in class than usual. I see Elias as one of the {#blank#}4{#/blank#}to get different kinds of practice and activities into the classroom," a teacher told Reuters.

    So far the school has {#blank#}5{#/blank#}  four robot teachers, one of whom is a language teacher that can speak 23 languages and dance to music. "It is {#blank#}6{#/blank#} to encourage kids to come up {#blank#}7{#/blank#}  new ways to make use of technology in school life," the head of the school {#blank#}8{#/blank#} in the interview.

    The robot teachers are used to {#blank#}9{#/blank#} improve learning. This doesn't mean that human teachers will lose their jobs. The robots can teach well, {#blank#}10{#/blank#} they are not able to keep class in order. The school still needs human teachers.
