Who designed (设计) the first helicopter (直升机)? Who{#blank#}1{#/blank#} one of the most famous pictures in the world? Who knew more about the human body than most {#blank#}2{#/blank#}? There is an answer to all these questions——Leonardo da Vinci. You might {#blank#}3{#/blank#}what I said, but it is true.

    Leonardo was a great genius (天才). He didn't study at a(n){#blank#}4{#/blank#}. About 1,500 years ago, he lived in Italy. He had lots of {#blank#}5{#/blank#}. One of them was inventing (发明) things. One of his notebooks had drawings of a helicopter. Of course, he wasn't {#blank#}6{#/blank#}to build a helicopter with the things he had. But{#blank#}7{#/blank#}said his idea worked.

    Leonardo wasn't just an inventor. He enjoyed painting. He was one of the greatest {#blank#}8{#/blank#}of his day. When he was young, he was an excellent painter. As he {#blank#}9{#/blank#}he became more famous. Many of Leonardo's wonderful{#blank#}10{#/blank#}are still with us today, for example, the smiling woman the Mona Lisa.

    Wang Ping is a cleaner. He has {#blank#}1{#/blank#} in a park for 5 years. He is also a good father. Nothing can make him {#blank#}2{#/blank#} than playing with his little daughter in his free time.

    Last Tuesday afternoon, while he was {#blank#}3{#/blank#} the park, suddenly, he heard a woman crying for help. He ran up {#blank#}4{#/blank#} to see what happened. The woman's 15-month-old baby girl choked (窒息) on a small piece of pear and her face {#blank#}5{#/blank#} purple. The baby was too young to save herself, and the mother was so nervous that she didn't know how to save her daughter properly.

    Luckily, Wang Ping knew what to do. He took the baby in his {#blank#}6{#/blank#} without thinking twice. With the mother's help, Wang Ping held the baby upside down and gave her a few pats (轻拍)on the back. After a short while, he succeeded in getting the piece of pear out of her mouth and the baby began to cry. Her mom was so thankful because her daughter was {#blank#}7{#/blank#}.

    Wang Ping tried his best and saved the {#blank#}8{#/blank#} life. In his mind, helping others is just helping {#blank#}9{#/blank#} He hoped more people could {#blank#}10{#/blank#} to help the people in need if possible.

      Bob was only seven years old. One night Bob was at home {#blank#}1{#/blank#} while his parents were out for a party. He had often stayed alone before, so he wasn't afraid. As he waited for his parents to {#blank#}2{#/blank#} home, he watched a film on TV. His eyes became heavier and heavier as time {#blank#}3{#/blank#} by.

      Suddenly Bob's eyes opened wide-what was the {#blank#}4{#/blank#} in the next room? Bob heard the window being opened slowly. For a minute, Bob was so {#blank#}5{#/blank#} that he could not move, and his body felt like ice. He knew that he couldn't lose his head (惊慌失措) and began to think of the things he could do. Again he heard the sound of someone trying to climb into his home {#blank#}6{#/blank#} the window.

      Bob's drums were standing in the corner near the TV. "Wait, {#blank#}7{#/blank#} there is something I can do," thought Bob. He {#blank#}8{#/blank#} on his drums as hard as he could. The sound was so terrible that Bob {#blank#}9{#/blank#} even himself. He also surprised the man in the window, who {#blank#}10{#/blank#} away as fast as possible. How clever he was!
