Dear basketball,

    When I rolled(使成球形)my dad's socks as a {#blank#}1{#/blank#}, I knew one thing was real: I fell in love with you. The love was so deep that I gave you my all {#blank#}2{#/blank#} my body to my soul(灵魂).

    As a six-year-old boy, I loved you deeply. I {#blank#}3{#/blank#} stopped loving you. I only saw myself running for you every court(场)all the time. You needed my effort, I tried my {#blank#}4{#/blank#}, because it asked for so much more. I played through me sweat(汗水)and the hurt, not because the challenge called me, {#blank#}5{#/blank#} because you called me. I did everything for you, became you made me feel alive.

    You gave a six-year-old boy his Laker(湖人)dream, and I will always love you for it. But now I can't love you any {#blank#}6{#/blank#}. This season is the last one for me. My {#blank#}7{#/blank#} can still best, my spirit can also fight, but my body' knows it's time to say, goodbye. {#blank#}8{#/blank#} of us accept it. And it's OK. I'm ready, to let you go.

    I want you to know now, then we can {#blank#}9{#/blank#} each other every moment we have left together.

    The good and the bad, we have {#blank#}10{#/blank#} one another all that we have. And we also know, whatever I do next, I will always be that kid with a basketball in my hands.

    Love you always.

Kobe

The 19^th Asian Games（亚运会）is held in Hangzhou, China this autumn. Many sportsmen come to the Games. They are from different{#blank#}1{#/blank#}in Asia. There{#blank#}2{#/blank#}three mascots（吉祥物）of the Hangzhou Asian Games. They are Chenchen, Congcong{#blank#}3{#/blank#}Lianlian. They are very cute and friendly. Everyone{#blank#}4{#/blank#}them. The sports gym looks{#blank#}5{#/blank#}a flower. It's beautiful, and it's{#blank#}6{#/blank#}big.

There are lots of games. I can watch{#blank#}7{#/blank#}on TV. My{#blank#}8{#/blank#}game is the men's skateboarding. The champion（冠军）is Chen Ye. Chen is from China. He is{#blank#}9{#/blank#}. He is 15 years old, and he is a{#blank#}10{#/blank#}in Huizhou. I am a student in Huizhou, too. I am so proud（骄傲）of him.

Where do our happy feelings come from? It's dopamine (多巴胺) that works as a star in our brains. It is often called the "feel﹣good" chemical (化学物质). When there's an ongoing dance party in our minds, dopamine is the DJ playing music of happiness. 

Dopamine is important not only because it controls our feelings, but also it plays a big role in different parts of our brains and bodies. As for brains, it influences our motivation (动机) and affects our learning and memory to help us keep knowledge for a longer time. As for bodies, it controls our body movement and helps us do actions more quickly, correctly and smoothly. Thanks to dopamine, we are encouraged to explore and learn more fun things, make more plans and want to achieve more goals. 

What can we do to make dopamine come out? It's interesting that everyday activities like exercise and even listening to music can help our brain to make it. Also, when we experience something enjoyable, like eating tasty food or reaching a goal, our brain releases dopamine. Besides, scientists have also found that dopamine isn't just about personal pleasure, but also does something with social interactions. When we talk with others, share a laugh or a bond with friends, our brains will also release dopamine. Dopamine keeps us feeling that it is enjoyable to be with others. 

However, too much or too little dopamine can be knotty, which means the brain's dance is not easy. If there's too much, it might make us feel too excited. If there's too little, it can make us feel a bit sad. Therefore, we should try our best to keep a balanced diet and do regular exercise, which is really important for a healthy and happy brain. 

So, if we find ourselves in a happy moment the next time, we should know that it's not just our heart dancing with joy, but also a wonderful dance of dopamine creating a beautiful ballet of happiness in our brain. Enjoy the dance, taste the joy, and let the chemistry of happiness lift the spirits to right heights!
