ss from the bus stop.” People in Los Angeles, the US, have no idea of distance on the map: they measure distance by time, not miles. “ How far away is the post office?” you ask. “ Oh,” they answer, “ it’ s about five minutes from here.” You don’ t understand pletely, “ Yes, but how many miles away is it, please?” To this question you won’ t get an answer, because most probably they don’ t know it themselves. People in Greece sometimes do not even try to give directions because tourists seldom understand the Greek language. Instead, a Greek will often say, “ Follow me.” Then he’ ll lead you through the streets of the city to the post office. Sometimes a person doesn’ t know the answer to your question. What happens in the situation? A New Yorker might say, “ Sorry, I have no idea.” But in Yucatan, Mexico, no one answers “ I don’ t know.” People there believe that “ I don’ t” is impolite.

Because scientists need a way to learn about past rainfall, they study tree rings. A tree’ s trunk grows bigger each year. Beneath its bark (树皮 ), a tree adds a layer of new wood each year it lives. If you look at a tree stump, you can see the layers. They are called annual rings (年轮 ) On some trees, all of the rings are he same width. But the ponderosa pines (松 ) that grow in the American southwest have rings of different width. The soil in the southwest is dry. The pines depended on rainfall for water. In a year of good rainfall, they form wide rings. In a dry year, they form narrow ones. Scientists do not have to cut down a pine to study its rings. With a special tool, they can remove a narrow piece of wood from the trunk without harming the tree. Then they look at the width of each ring to see how much rain fell in the year it formed. Some pines are hundreds of years old and have hundreds of rings. These rings form an annual record of past rainfall in the Southwest. 11. The story does not say so,。
