Australian Aborigines (土著居民)

Some aborigines live in the desert of Western Australia. They gather wild plants and hunt wild animals. Their desert environment averages less than eight inches of rain per year. And the temperature in summer may rise to 48°C. The few permanent (永久的)water holes are separated by hundreds of square miles of sand and rock.

On a typical day, the aborigines get up just before sunrise. The people breakfast on water and food left over from the night before. Children are sent to fetch water. In the cool of the early morning, the adults talk and make plans for the day. Where should they go for food-to places they have been to recently, or to new places? The women decide which plants they want to collect, and where those plants are most likely to be found. Then they take up their sticks and set out with large wooden bowls of drinking water on their heads. Their children ride on their hips (胯)or walk alongside. Meanwhile, the men may have decided to hunt animals. They go to a stream where they will wait to get any animal that may come along. They lie patiently behind a screen of bush they have set up, hoping for a chance to throw a spear (矛)at the animal. If they miss, the animal will run away. So they can only throw once.

By noon, the men and women are back at camp. The women are usually with their wooden bowls each filled with fruits or other plant foods; the men are often with only some small animals such as rabbits. Since the men's food-getting is less certain of success than the women's, most of the aborigines' diet is plant food.

Keeper of the Spring

An old man lived in a quiet forest high above an Austrian village along the eastern side of the Alps (阿尔卑斯山).He had been hired many years earlier by a young man from the town council (委员会)to clear away the rubbish from the pools of water up in the mountain that fed the lovely spring flowing through their town. Faithfully and silently, he walked around in the hills every day removed the leaves and branches, and wiped away the mud that would otherwise have choked and polluted the fresh flow of water The village soon became a popular attraction for vacationers.

Years passed. One evening the town council met for its monthly meeting. As they reviewed the budget, one man's eye caught the salary being paid to the keeper of the spring. Said the keeper of the purse, “Who is the old man? Why do we keep him on year after year? No one ever sees him. For all we know, he is doing us no good. He isn't necessary any longer. After a vote, they stopped the old man's services.

For several weeks, nothing changed.

By early autumn, the branches and leaves of trees began to fall into the pools, blocking the rushing flow of water. Within a few days, the water became darker and darker. Within another week, a terrible smell was detected (觉察).Soon, fingers of disease reached deeply into the village.

Realizing their error of judgment, the council rehired the old keeper of the spring and, within a few weeks, the river of life began to clear up.

Super Sense of Smell

① Dogs have a surprising sense of smell. It allows them to perform excellently at search-and-rescue operations. It also enables them to detect bombs. They can even sniff (嗅) out chemical changes resulting from certain diseases. Therefore, dogs are trained to save people's lives.

② Dogs begin training when they are two months old. Their owners drop them off at training centers from 9 am. to 5 p.m. every weekday. During the time, trainers p场 hide-and-seek with the dogs to train their sense of smell. They teach the dogs to climb ladders and run past obstacles (障碍).They also expose the dogs to loud noises.

③ Diseases have specific smells. Although the smells are usually too subtle for human noses to detect, dogs can tell something is wrong and warn people about the problem by barking. Many people have reported that their dogs warned them of an illness.

④ Scientists are training dogs to detect disease. A dog is asked to sniff a wheel. Blood samples from different people are attached to the outside of the wheel. Blood from a cancer patient has a slightly different smell than blood from a healthy person. The dog must figure out which blood sample to pick.

⑤ Scientists are working to design an electronic nose that can sniff out cancer. To do that, they need to figure out what molecules (分子)are sent out from the cancer Then they can create a mixture with similar smell to that of the cancer. Once scientists know which molecules match the cancer's smell, e-nose could be designed to detect cancer.
