air pollution can cause both airplane and auto accidents because it cuts down visibility.there are other possible health dangers from air pollution that we do not know much about.for example,scientists are trying to find out whether chemicals that reach us from the air may cause changes in our cells.these changes might cause babies to be born with serious defects.scientists are trying to learn how all the many chemicals we are apt to take into our bodies from air,water,food and even medicines act together to affect our health and the way our bodies work.that is another reason why it is so important to begin to control pollution now instead of waiting until we learn all the answers.
air pollution costs us a lot of money.it dirties and corrodes our buildings.it damages farm crops and forests.it has a destructive effect on our works of art.the cost of all this damage in the united states is thought to be more than $16 billion every year.this is far more than the cost of controlling air pollution would be.

Two men were sitting together in an airplane.They were on a long journey.
One of the men was a teacher.The other was a farmer.
They sat without talking for a while,then the farmer said,"Let's do something to pass the time."
"What do you want to do?" the teacher asked.
"We can ask each other riddles," the farmer said."You start."
"Let's make the rules first," the teacher said."And let's make the game more interesting.Let's play it for money.If we don't know the answer to a riddle,we have to pay a dollar."
The farmer thought about this for a while,then he said,"That's not fair.You are a teacher,an educated man.You know more things than I do.I am just a farmer."
"That's true," the teacher said."What do you think we should do?"
The farmer said,"If you don't know the answer to a riddle you pay me $100.If I don't know the answer to a riddle,I'll pay you $50."
The teacher thought about this,then he said,"O.K.That's fair.Who'll go first?"
"I will," the farmer said."Here is my riddle.What has three legs when it walks,but only two legs when it flies?"
The teacher repeated the riddle,"What has three legs when it walks,but only two legs when it flies?Mm,that's a good one.I'm afraid I don't know the answer."
He gave the farmer $100,then said,"Tell me the answer.What has three legs when it walks but only two legs when it flies?"
"I don't know," the farmer said,and gave the teacher $50.

Flying over a desert in an airplane, two scientists looked down with trained eyes at trees and bushes．After an hour’s flight, one of the scientists wrote in his notebook, "Look here for probable metal." Walking across hilly ground, four scientists reported, "This ground should be searched for metals." From an airplane over a hilly wasteland a scientist sent back by radio one word "Uranium". None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth’s surface．They were merely putting to use one of the newest methods of locating minerals in the ground -- using trees and plants as signs that certain minerals may lie under the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface. At Watson Bar Creek, a mineral search group gathered bags of tree seeds．Boxes were filled with small branches from the trees．Roots were dug and put into boxes．Each bag and box was carefully marked．In a scientific laboratory the parts of the forest trees were burned to ashes and tested．Each small part was examined to learn whether there were minerals in it. Study of the roots, branches and seeds showed no silver．But there were small amounts of gold in the roots and a little less gold in the branches and seeds．The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches. If the trees indicated that there was no gold in the ground, the scientists wouldn’t spare money to pay for digging into the ground. 小题1:Scientists were flying over a desert or a hilly wasteland or a mountain region to _____. A．train their eyes B．study the trees C．look for gold D．search for minerals 小题2:The study of trees, branches and roots indicated that ______. A．there were larger amounts of gold in the branches far from the tree trunk than in the seeds B．there were smaller amounts of gold in the tree roots deep in the ground than in the branches C．there were larger amounts of gold in the seeds growing closer to the tree trunk than in the seeds farther from it D．there were larger amounts of gold in the branches than in the leaves on the ends of the branches 小题3:Which of the following is NOT mentioned as part of a tree that can help the searchers? A．leaves B．roots C．branches D．seeds 小题4:Which of the following might be the best title for this passage? A．Scientists searching for treasure with special equipment. B．New methods of doing geological study. C．Gold could be found in trees and plants. D．A new method of searching for minerals.
