In 1715 ,at fleet(舰队) of Spanish ships left Havana, Cuba for Spain. On their way home, they ran into bad weather. Eleven ships--along with{#blank#}1{#/blank#}of treasure they were carrying--were lost. About 1,000 people{#blank#}2{#/blank#}.

    For nearly 250 years, the sea kept most of the treasure to itself. Then, in the 1950s, a man found coins and some {#blank#}3{#/blank#} treasure on a Florida beach. He soon {#blank#}4{#/blank#} that one of the Spanish ships must have been nearby(;(在附近). That's when a big undersea treasure hunt(搜寻) began.

    Two big discoveries were {#blank#}5{#/blank#} just in the summer of 2015. In June, some professional treasure hunters found coins and jewellery worth over $1 million. There was even one gold coin that was worth over

 $500,000 {#blank#}6{#/blank#}. The following month, a team of treasure hunters found 350 gold coins, together worth $4.5 million. So far, about $400 million worth of treasure is said to have already been found.

    So who can {#blank#}7{#/blank#} treasure found at sea? Each case(情况) is different, but in the case of the 1715 fleet, 20 percent goes to the state of Florida for its museums. Other treasure is 2{#blank#}8{#/blank#} between Queens

Jewels and whoever finds it. Queens Jewels is a company who owns the rights (权利) to the fleet.

    Even if you are not {#blank#}9{#/blank#} to keep what you find, there is plenty of reason to be excited. "These finds are {#blank#}10{#/blank#} not just for how much they are worth, but their historical importance," says the owner of Queens Jewels.

    Why is music important to people? Because life {#blank#}1{#/blank#} music wouldn't be exciting. Different kinds of music express different feelings and life {#blank#}2{#/blank#}. So when we listen to different kinds of music, they can bring us different {#blank#}3{#/blank#}. For example, rock music can make you {#blank#}4{#/blank#}, classical music can make you relaxed, and country music can make you think of the {#blank#}5{#/blank#}country life.

    At different ages, people have different {#blank#}6{#/blank#} about music. Young people today {#blank#}7{#/blank#}pop music while their parents {#blank#}8{#/blank#} to listen to classical music. Perhaps this is because young people are {#blank#}9{#/blank#} of energy and faster music can let their energy come out. Their parents have worked very hard during the day and they have got {#blank#}10{#/blank#} when they come back home. So they would listen to classical music to make them relaxed.

Dear Xia Yu,

    Do you know that there are two special days for parents in America? One is Mother's Day on the second Sunday of May, and the other is Father's Day on the {#blank#}1{#/blank#} Sunday of June. On these two days, {#blank#}2{#/blank#} children often give gifts to their parents or take {#blank#}3{#/blank#} for lunch or dinner. Common gifts are flowers and cards for mothers and shirts or ties for fathers. I heard that it is {#blank#}4{#/blank#} more and more popular to celebrate Mother's Day and Father's Day in China. I wonder if children over there also give similar gifts to their parents. I believe that there are many ways to show our love. Actually, we don't have to spend a lot of money. It is also a good idea to help parents {#blank#}5{#/blank#} something instead.
