Hello, everyone! Tomorrow we'll go for a trip in the mountains. Before we start, there are some {#blank#}1{#/blank#} and suggestions for you. First, everyone should {#blank#}2{#/blank#} sports shoes. Second, when you walk in the mountains, you mustn't walk too {#blank#}3{#/blank#} "to the edge of the path. Third, you must keep {#blank#}4{#/blank#} or you'll get lost. Fourth, bring some water with you, or you'll be {#blank#}5{#/blank#}.

    We need to put up a tent to stay at night in the mountains. Be careful of the {#blank#}6{#/blank#} when you are in the forest. Although some animals look {#blank#}7{#/blank#} they are really dangerous. If you meet animals, don't move suddenly. Just keep still until they {#blank#}8{#/blank#}. Remember to hang your food in the tree before you go to sleep Hope everyone can have a good trip.

    As we know, people who can't see anything live difficult lives. They may have{#blank#}1{#/blank#}(苦恼)in going out. Also, they feel {#blank#}2{#/blank#}(寂寞)when they stay at home alone. Can people save these problems?

    In 1918, a doctor and his pet dog walked with a {#blank#}3{#/blank#}(眼瞎的) soldier. The doctor had something to do in the hospital, so he left his pet dog and the soldier for a short time. When he came back, he {#blank#}4{#/blank#}(注意到)his pet dog guided the soldier safely. So he made a {#blank#}5{#/blank#}(决定)that he would teach dogs to guide persons and he succeeded at last. This made the people who can't see {#blank#}6{#/blank#}(兴奋的).

    The best dogs for the job are clever. It takes more than two years to {#blank#}7{#/blank#}(训练) a little dog to be a guide-dog. When the dog is 14 months old, it can understand people's instructions(指令) easily. Then it will meet its new {#blank#}8{#/blank#} (主人)and they need to practice together for four weeks. With the help of the guide-dog, the disabled people become {#blank#}9{#/blank#}(独立). They never {#blank#}10{#/blank#} (依靠)on others.

    There was once a jeweler (珠宝商), famous for many virtues (美德). One day, some Arabs came to him for some diamonds to decorate an important thing for a yearly celebration.

    The Arabs told him what they wanted, and p{#blank#}1{#/blank#} a fine price for him. He replied that he could not let them see the jewels at that moment, and needed them to come again.

    B{#blank#}2{#/blank#} they wanted the diamonds very much and thought that the p{#blank#}3{#/blank#} of the jeweler was only to increase the price of the diamonds, the Arabs offered him twice, then three times as much as they were worth. But he still r{#blank#}4{#/blank#}, and they were quite disappointed and went away.

    Some hours later, he went to the Arabs and p{#blank#}5{#/blank#} the diamonds before them, for which they again offered him the last price, but he said, "I will only accept the first p{#blank#}6{#/blank#} you offered to me this morning."

    "Why, then, did you disagree with us at first?" asked they in s{#blank#}7{#/blank#}.

    "When you came," replied he, "my father had the key to the safes (保险箱), in which the diamonds were locked, and as he was asleep, I would have to w{#blank#}8{#/blank#} him to gain them. At his age, a short of sleep u{#blank#}9{#/blank#} does him good; and no business is more important than my father's health."

    The Arabs were t{#blank#}10{#/blank#} by his words. They spread their hand upon the jeweler's head and showed their satisfying smiles.
