Dr Watson was a good friend of the famous detective Sherlock Holmes. One morning they {#blank#}1{#/blank#}(eat) breakfast when suddenly Holmes said, “I have to go to a place {#blank#}2{#/blank#} (call) Coland. A horse has disappeared from there, and the police can't find it. Will you come with me?”

    “Do you think that the horse {#blank#}3{#/blank#}(steal) the other day?” Watson asked.

    “I don't know,' Holmes replied. “ I need to go to Coland {#blank#}4{#/blank#}(find) out.”

    “Why is this horse so important, Holmes?” Watson asked.

    “Because I {#blank#}5{#/blank#}(run) in a big race. If it wins, a lot of people will win a great deal of money. There are also people who {#blank#}6{#/blank#}(not want) it to win.”

    An hour later, they were on the train to Coland.

    Waste can be seen everywhere and it can bring a lot of problems. China is rich in some resources(资源), {#blank#}1{#/blank#}we are short of other resources like fresh water. It is said {#blank#}2{#/blank#}we will have no coal(煤) or oil to use in 100 years. Also there is not enough food in some areas.So if we keep {#blank#}3{#/blank#}our resources, what can we use in {#blank#}4{#/blank#}future and where can we move? Think about it, I think we should say "no" to the people {#blank#}5{#/blank#} waste things every day.

    In our {#blank#}6{#/blank#} life, we can do many things to stop waste from happening. For example, remember to turn {#blank#}7{#/blank#} the lights when we leave the room and we'd better use both {#blank#}8{#/blank#} of paper. Also we should try not to order {#blank#}9{#/blank#}food than we need. Little by little, everything will be changed, waste can be stopped one day {#blank#}10{#/blank#}we do our best.

— Yes. And {#blank#}1{#/blank#} are twins(双胞胎).
