—It s{#blank#}1{#/blank#} good.

    One day，Daniel and his uncle Bob went to the store together．Uncle Bob gave Daniel a one—dollar bill and told him he could buy{#blank#}1{#/blank#}(无论什么)he wanted with that money. Daniel picked out two chocolate candy bars which cost{#blank#}2{#/blank#}(五十)cents each．

    As they were{#blank#}3{#/blank#}(离开)，his uncle said that when he was a {#blank#}4{#/blank#}(孩子)he was able to buy five candy bars with one dollar．This was because back then，they only cost 20 cents each．Daniel became{#blank#}5{#/blank#} (惊奇的)．

    "You see，Daniel，the{#blank#}6{#/blank#}(价格)of all things usually goes up as time goes by．That's why one dollar earned today is more valuable than one dollar earned one year later．This is called the Time Value of Money．Do you understand?" "Not really，"Daniel replied{#blank#}7{#/blank#}(快地)．

    "Look at the candy bars in your{#blank#}8{#/blank#}(手)．When l was a kid，I could buy five of them with one dollar．But now，l can only buy two because the cost has {#blank#}9{#/blank#}(上涨)to 50 cents．In other words，the value of one dollar has dropped over the years．''

    Daniel nodded his head．Now he was a little {#blank#}10{#/blank#}(确信)what his uncle meant．Bob smiled．

    Nowadays, many families keep a dog, a cat, a bird or a snake as a pet. Some c{#blank#}1{#/blank#}that live in big cities are very fond of keeping pets in the house, especially the old, because they always feel lonely at home. Thus, they can see the pets as their f{#blank#}2{#/blank#}members. Keeping pets around them is quite a good way for young parents to educate their children. What's more, pets can a{#blank#}3{#/blank#} look after the house when there's no one at home. Some of them even say that animals are as good as humans, and they should be r{#blank#}4{#/blank#}.

    However, others think that keeping pets is not good. They say that animals are noisy, dirty and dangerous. Taking the pets when taking public transport like buses is not so convenient, b{#blank#}5{#/blank#}other people might hate animals. They think some measures should be taken to stop people from keeping pets in cities and towns.

    I think that it depends on ourselves whether it's good to keep a pet or not. But if one keeps pets, he or she should wash pets r{#blank#}6{#/blank#}to keep them clean. In my opinion, pets are our good friends. Staying with pets, we shall enjoy happiness and feel relaxed. That is to say, keeping pets helps us to forget our u{#blank#}7{#/blank#}things for a moment. What's more, keeping pets lets us learn about life and death. We should love life.
