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.
