    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.

    Share your feelings when you need help. Sharing a problem is like cutting it {#blank#}1{#/blank#}However, maybe it's really hard to tell someone that you are feeling {#blank#}2{#/blank#}or worried. If you are too shy and want to be a little braver than before, please listen to my {#blank#}3{#/blank#}.

    Talk with your parents. Your parents have more {#blank#}4{#/blank#}than you. And they never {#blank#}5{#/blank#}to help you. But sometimes communication (交流) between parents and children is a problem. So if you don't want to talk with your parents, what should you do It's a good idea to find someone you {#blank#}6{#/blank#} to talk to like a teacher. He or she can help you {#blank#}7{#/blank#} your problems.

    After finding someone you can talk to, you need to decide how to talk about your problems. If you {#blank#}8{#/blank#} it's difficult for you to say what you think, write it down on a(n){#blank#}9{#/blank#}of paper. It might help.

    Problems and worries are normal in life. But {#blank#}10{#/blank#}you talk about them with others, you could make yourself ill (不舒服). So please deal with (处理) your feelings in a right way before it's too late.
