Last year, my brother and I went to Miami for a vacation. Some of my friends who had been there before said {#blank#}1{#/blank#} was a Wonderful holiday destination. Before we went, we had planned for months. When the day came, we were ready.

    After our plane landed, we went to the hotel. We had made our reservation six months{#blank#}2{#/blank#}(early), but the man at the front desk said there had been a mistake. We{#blank#}3{#/blank#}(tell) that our rooms hadn't been reserved for that week,{#blank#}4{#/blank#} for the week after. I didn't understand {#blank#}5{#/blank#}this would happen and my credit card had already been charged {#blank#}6{#/blank#} the reservation. What's worse, the hotel had been fully hooked. When we were wondering what to do, the manager came out. She was {#blank#}7{#/blank#}(surprise) helpful. She apologized for the mistake and gave us a spare VIP room on {#blank#}8{#/blank#} top floor. We had never stayed in such an amazing room, and we weren't charged extra.

    The next day, my brother and I went to the beach {#blank#}9{#/blank#} we watched some people play volleyball. We got a little {#blank#}10{#/blank#}(sunburn), but the day had been so relaxing that we didn't mind.

    Have you ever wondered{#blank#}1{#/blank#}children always seem to have bags of energy and never run out of steam? Researchers have discovered that children have the levels of recovery of endurance athletes. In fact, scientists say children's muscles recover from "high-intensity exercise" a lot{#blank#}2{#/blank#}(quick) than athletes. A study looked at the performance levels of children when they were cycling, and compared their fitness to {#blank#}3{#/blank#}of athletes. Researcher Dr Sebastien Ratel suggested they {#blank#}4{#/blank#} (find) the children used more of their aerobic metabolism and were therefore less tired during the high-intensity physical activities. The children also recovered very quickly-even faster than the well-trained adult endurance athletes.

    The researchers hope that{#blank#}5{#/blank#}(they) findings will help scientists have a better{#blank#}6{#/blank#}(understand) how the human body changes with age. It could lead to advances in the fight {#blank#}7{#/blank#} diabetes and other diseases. Dr Ratel said the research was{#blank#}8{#/blank#}(particular) important as more children were become less active. He warned: "With the diseases related to physical inactivity{#blank#}9{#/blank#}(rise), know the changes with growth that might contribute to the risk of disease. "{#blank#}10{#/blank#}is helpful for children to maintain their fitness as they grow up and play as much as they could so they remain healthy as adults.

    "If you're talking to me in a noisy restaurant and my nerve system is good at locking onto the sound of your voice, I {#blank#}1{#/blank#} understand what you say better."

    The research at Northwestern University shows that {#blank#}2{#/blank#} (play) a musical instrument is good for your brain. And the brain remembers how to "lock onto" the important sounds, {#blank#}3{#/blank#}, our ears may not work as well as we age, and that helps us to hear better.

    A scientist, living in France twenty years ago, {#blank#}4{#/blank#} (write) about what he called the "Mozart Effect". He said that {#blank#}5{#/blank#} could be helpful to the brain when listening to the classical music of Mozart. Some researchers said that Mozart's music would make you much {#blank#}6{#/blank#} (smart), or even have some health disorders {#blank#}7{#/blank#} (cure). Others said that there was nothing special about Mozart's music. Any kind of high energy music would work. So if the cost of a musical instrument or music lessons is too costly, can we get {#blank#}8{#/blank#} same brain experience just by listening?

    Usually people have teachers, or they can teach themselves music. {#blank#}9{#/blank#}, the point is that they're actively playing a musical instrument and engaging in making music instead {#blank#}10{#/blank#} listening to music passively.

    The 2012 Olympic and Paralympic (残奥会)Games brought the world's attention to sport like never before. It was admirable {#blank#}1{#/blank#}(see) a small nation like the UK organize the Olympic for {#blank#}2{#/blank#} third time in modern history.

    Britain probably {#blank#}3{#/blank#}(invent) quite a few modern sports. One is cricket (板球), {#blank#}4{#/blank#} is now played at international level in a dozen countries. Tennis also first became popular here and Wimbledon is one of the four big tournaments every year. Golf{#blank#}5{#/blank#} (suppose) to be Scottish in origin (起源)from a school of the same name.

    Every town in Britain has football, rugby or cricket club (sometimes all three) and at least one swimming pool. Schools have a gymnasium and playing fields with a running track. As British is an island, there are lots of opportunities for practising water sports {#blank#}6{#/blank#} well.

    "Fair play" in British society is as important as {#blank#}7{#/blank#} (win) or losing. Teamwork is also necessary in many areas of professional life. Even so, individualism (个性)and competitiveness make sporting champions. Steve Redgrave, winner of five gold {#blank#}8{#/blank#}(medal) at five Olympic Games, says: "Being {#blank#}9{#/blank#} (confidence)in yourself is the most important in sporting success. {#blank#}10{#/blank#}(personal), it is the iron in the mind not the supplements (增补物）that wins medals."
