A: Time flies! It's time to say goodbye to my junior high school!. When looking back at these past three {#blank#}1{#/blank#} (year), I remember many things.

B: Yeah, I will miss Ms. Miller very much. She was so patient with me that she took the time to explain things to me {#blank#}2{#/blank#}(clear) whenever I couldn't understand {#blank#}3{#/blank#}(something). And she guided me to do a lot {#blank#}4{#/blank#}(good) in English.

A: I used to be weak in English,{#blank#}5{#/blank#}because of Ms. Miller, I put in more effort and my scores doubled. She {#blank#}6{#/blank#}(teach) us so well.

B: She was also strict with us and nobody was allowed to arrive late {#blank#}7{#/blank#}morning readings.

A: But she was also friendly and always made her classes {#blank#}8{#/blank#}(interest). I always remember the excitement.

B: Yes, we were lucky to spend time  {#blank#}9{#/blank#}our kind and caring teachers.

A: Shall we get each of them a card and a gift to say thank you?

B: OK. Let's make a card by{#blank#}10{#/blank#}(we)

A: Good idea.

    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.
