A big, mighty(高大的) tree stood in a forest. Its branches(树枝) spread out and its roots (根) went deep in the earth. A lot of people came here to have a rest under it. And a lot of birds stood on its branches to sing and dance. The big tree was very proud all the time.
At the foot of the tree, there was a little plant. The plant was thin, and seemed to be blown down by any of a little wind.
One day, the two neighbors were having a little chat.
“Well, little one,” said the tree to the plant, “why not put your feet deeply in the earth, and raise your head high in the air as I do?”
“I see there is no need to do so,” said the plant with a smile. “In fact, I think I may be safer in this way.”
“Safer?” said the tree. “Are you safer than I am? Do you know how deep my roots are in the earth and how strong my branches are? Who can possibly pull me out by the roots or bow my head to the ground?” And the tree didn’t want to say anything to the weak plant.
But the tree was to regret its words very soon. One evening, a great hurricane(飓风) came. It blew the trees off their roots and almost destroyed the forest completely. It uprooted（将……连根拔起）the mighty tree and blew it away with great force.
When the storm had gone, the villagers living nearby came to check the damage. The mighty tree lay on the ground, but the little plant still stood there.

Someone is singing next door, but you feel unhappy because her singing is terrible. So you think she is just making noise. We know that too much noise makes people feel terrible.
Scientists are still trying to find out more about noise, but already it is known that a noise of over 85 decibels(分贝) can make some people tried and anxious(焦虑的).
In the past we thought only workers in very noisy places became deaf easily. Today, scientists believe that 10% of all workers in Britain become deaf in their work.
There are also new dangers from noise. Pop music, for example, can reach 120 decibels when it is played loudly five feet away! Only a plane can make such loud noise when it takes off.
There was an experiment in the United States. Some people would be given a lot of money if they stood below a jet when it was taking off over their heads. No one got the money after the jet flew past because all of them died in the noise.
People can’t pay their attention on what they are doing when there is much noise. Workers in noisy offices, for example, do their work more slowly than workers in quiet offices. Another study shows that workers in factories can do dull(枯燥的) jobs better when lively music is played for them.
| Topic | Too much noise makes people feel ___1____ |
| Sources(源) of noise | . terrible singing . pop music when it is played ___2____ nearby . loud noise made by a plane taking off overhead |
| Harm of noise | . A noise of over 85 decibels can make people feel tired and anxious. . 10%of all workers in Britain become ___3___ in their work. . Some people lose their ____4___ in the noise of a plane taking off over their heads. . Workers in noisy places do their work more ___5___ than those in quiet places. |
