What's the most popular school activity among American students? The{#blank#}1{#/blank#}  is the school dance. Most American high schools have at least two dances {#blank#}2{#/blank#}  the year, one in winter and the other in spring. Students attend these events {#blank#}3{#/blank#}  it's a great opportunity for them to meet {#blank#}4{#/blank#}  friends.
     At the dance, there will be snacks and photo booths (机器拍照亭), as well as strict（严格的） rules to {#blank#}5{#/blank#}  create a healthy and enjoyable evening for all students. And all the dancers will be given a security check（安检）before they come into the dance {#blank#}6{#/blank#} . This is acceptable. But some rules may be a little bit over the top（过分). For example, a school once asked {#blank#}7{#/blank#}  students to keep a standing position while they were dancing. That {#blank#}8{#/blank#}  the students couldn't do anything freely. You'd {#blank#}9{#/blank#}  not break the rules because you'll be asked to leave there, or even worse, be placed on a do not invite list.

    I am a doctor. People often come to see me because they have colds or coughs. People {#blank#}1{#/blank#} come to see me because they are sad or nervous. Sometimes {#blank#}2{#/blank#} helps. Sometimes talking helps. But many doctors {#blank#}3{#/blank#} that music can help people feel better. I asked a few of my patients(病人) how music helps them. 

    "Sometimes I was {#blank#}4{#/blank#} when I was a child. My family said, 'Play your feelings on the piano!" Sometimes I play aloud {#blank#}5{#/blank#} on the piano. Soon I feel calm（平静的）. I can laugh and cry through my {#blank#}6{#/blank#} on the piano. It's natural for me. It's like breathing (呼吸）." "Listening to music helps me feel {#blank#}7{#/blank#}. I like to listen to music and dance when I {#blank#}8{#/blank#} my house." "I play the violin. I like playing at night {#blank#}9{#/blank#} it is quiet. After playing I am tired and I am happy. I always sleep {#blank#}10{#/blank#} after playing my violin." Are you a musician? Good! Keep playing. If you are not a musician, listen to music and sing or dance. It's good medicine.

    Are robots as smart as humans? Scientists are now {#blank#}1{#/blank#} to make robots look like humans and do the same things as we do. Some robots in Japan can walk and dance. They are fun {#blank#}2{#/blank#}. However, some scientists believe that although we can make robots move like people. There will be {#blank#}3{#/blank#} to make them really think like a human. For example, scientist James White thinks that robots will never be able to wake up and know {#blank#}4{#/blank#} they are. But many scientists disagree with Mr. White. They think that robots will even be able to talk {#blank#}5{#/blank#} humans in 25 to 50 years. Everything is possible in the future.
