Once there were several scientists in a forest. They were trying to 1 the rarest animal in the world. No one had seen it, so everyone was 2 and wanted to be the first one to photograph and study it.

    The animal only came out at night, 3 the scientists did some other studies in the day. 4 them, there was a famous scientist named Walter. Every day, he would spend an hour sitting at the desk and putting all his equipment (设备) in the 5 place. He did this carefully. But other scientists laughed at him because they thought Walter was just wasting 6.

    One night, the animal appeared 7. The scientists heard its call. But the call didn't last long. The animal was frightened by the 8  made by the scientists while they were scrabbling (忙乱地找) for their cameras and notebooks.

     On the next morning, the scientists 9 their findings. Some had tried to record its call, others had noted down how it moved, and the luckiest one had even photographed parts of its tail and legs. They all congratulated each other on what they had found. However, when they saw what Walter had, they were very surprised. 10 had taken several complete (完整的) photos, the record of the animal's cry and notes about the animal.

    They ran to congratulate Walter. They now understood the importance of keeping things in order. Because of that, Walter could find everything quickly in the dark.

    You {#blank#}1{#/blank#} (get) different answers if you ask people from different countries," Could you tell me the way to the post office?"

In Japan, people use landmarks instead of street names. For example, the Japanese will say to {#blank#}2{#/blank#} (travel),"Go straight down to the corner, turn left at the big hotel and go past a fruit market. The post office is {#blank#}3{#/blank#}(cross) from the bus stop.

    In the Midwest of America, there are no towns {#blank#}4{#/blank#} buildings within miles. So instead of landmarks, people tell you directions and distance. In Kansas, {#blank#}5{#/blank#}example, people will say, "Go north two miles, turn east and then go another mile."

    People in Greece sometimes do not even try {#blank#}6{#/blank#} (give) directions because few visitors understand Greek. Instead of giving you directions, a Greek will often say, "{#blank#}7{#/blank#} (follow) me." Then he or she will lead you across the streets {#blank#}8{#/blank#} the post office.

    Sometimes if a person doesn't know the answer to your question, he or she, like a New Yorker, might say, "Sorry, I have no idea." {#blank#}9{#/blank#} in Yucatan, Mexico, no one answers "I don't know." People in Yucatan think "I don't know." is not polite. They usually give an answer, but often a wrong one. A visitor easily get {#blank#}10{#/blank#} (lose) in Yucatan.
