　　Do you know something about tree rings(年轮)? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?

　　A tree will grow well in a climate(气候)with lots of sunshine and rainfall．And little sunshine or rainfall will limit(限制)the growth of climate by studying the tree rings．For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside．If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year．If it is near to the eleventh ring, then the climate that year was bad．

　　Tree rings are important not only for studying the history of weather but also for studying the history of man．Many centuries ago there lived a lot of people at a place in New Mexico．But now you can find only sand there－no trees and no people．What happened?

　　A scientist studied the rings of dead trees there．He found that the people had to leave because they had cut down all the trees to make fires and buildings．As all the trees had gone, the people there had to move．

　　Mr and Mrs Wu were mad at their neighbor．He was always borrowing things from them．

　　“It’s not right．”Mr Wu said to his wife one evening, “At one time or another that man has borrowed nearly everything we have．Almost every day he comes over to borrow something．”

　　“You’re quite right．”his wife replied, “and most of the things he’s never returned．”

　　“What I want to know,”her husband said, “is why he can’t buy the things he needs, like everyone else?”

　　“Because people like us are foolish enough to lend him what he needs．”she replied, “As long as we are willing to lend, he’ll keep on borrowing．”

　　“Then we’ll never lend him anything again．”Mr Wu said, “The next time he asks to borrow something, I’ll say no．”

　　“We must have a good reason for saying no．”his wife said, “and we must always try to be polite to him．We don’t want to make an enemy of the man．”

It was not long before their decision not to lend their neighbor anything even again was put to test．

　　The next morning there was a knock on the door．

　　Mr Wu went to answer it．

　　Their neighbor was standing there．Mr Wu knew he was going to ask to borrow something, and was ready to refuse him politely．

　　“Good morning．”their neighbor said, “I’m sorry to trouble you, but I wonder if I could borrow your garden scissors?”

　　“I’m sorry,”Mr Wu said, “but I’m afraid my wife and I will be using them today．We’ll be spending all day working in the garden．”

　　“Oh, I see．”the neighbor said．“In that case, may I borrow your golf clubs(高尔夫球椿)？You won’t be needing them if you’re working in the garden all day, will you?”
