[06:30.92]"The bird talks.I just don't like his attitude."
[06:36.51]Puzzled,the store owner said,"You're right.I don't understand.
[06:43.51]Explain it to me." The customer said,
[06:49.03]"I bought the bird a week ago.
[06:52.92]Every morning,I stood in front of his cage and asked,Can you talk?'
[07:00.21]I did the same thing every evening.For six days,I got no response.
[07:07.99]Then,this morning,I shouted at the bird,
[07:13.58]'CAN YOU TALK,YOU STUPID CREATURE?CAN YOU TALK?"'
[07:19.17]The customer glared at the parrot.The owner asked,
[07:24.66]"So,what happened?""That bird looked at me," the customer said,
[07:31.76]"and said,'I can talk all right.Can you fly?'"
[07:37.87]4.3 Note-talking 3.Now listen to the passage,
[07:46.86]and use the spaces in your book
[07:50.47]to take down some notes about each point.
[07:54.78]Environmental pollution is a term that refers to all the ways
[08:01.57]by which humans pollute their surroundings,for example
[08:07.76]by damaging the soil with too many fertilizers and pesticides.
[08:14.16]We also pollute our surroundings in various other ways.
[08:19.85]People ruin natural beauty by scattering junk and litter
[08:25.84]on the land and in the water.
[08:30.04]They operate machines and motor vehicles
[08:35.24]that fill the air with dangerous exhaust and disturbing noise.
[08:42.03]Nearly everyone causes pollution in some way.
[08:47.44]Environmental pollution is one of the most serious problems
[08:53.94]that mankind faces today.
[08:57.94]Air,water,soil--all of which are harmed by pollution
[09:04.73]--are necessary to the survival of all living things.
[09:10.43]Badly polluted air can cause illness and even death.
[09:16.51]Polluted water kills fish and other marine life.
[09:22.52]Pollution of the soil reduces the amount of land
[09:28.82]on which we can grow food.
[09:32.50]Environmental pollution also brings ugliness
[09:38.19]to the naturally beautiful world.
[09:42.37]Everyone wants to reduce pollution.
[09:47.15]But the pollution problem is as complicated as it is serious.
[09:54.05]It is complicated because
[09:57.73]so much pollution is caused by things that benefit people.
[10:03.82]For example,exhaust from automobiles
[10:09.20]causes a large percentage of all air pollution.
[10:14.71]But the automobile provides transportation for millions of people.
[10:21.11]Factories pollute the air and water,but also provide jobs for people.
