Is the music soft and beautiful?Ss: Yes. It is enjoyable.Suddenly Teacher turns up to its full volume.Ss: Terrible noise!T: Yes, we call this much too loud music noise pollution. In this class we are going to listen to a radio programme about noise pollution.Step II Listening: A radio InterviewSs: Noise from road traffic, jet planes, jet skis, garbage trucks, construction equipment, manufacturing processes, lawn mowers, leaf blowers, and boom boxes, to name a few, are among the audible litter that are routinely broadcast into the air.T: Noise negatively affects human health and well-being. Can you name some problems cause by noise?Ss: Problems related to noise include hearing loss, stress, high blood pressure, sleep loss, distraction and lost productivity, and a general reduction in the quality of life and oppo rtunities for tranquility.T: Quite right! Now that you know a lot about noise, please work in groups and do Ex1&2 on Page 12. Several minutes later ask some students to present their answer s to the class....（After students presented their answers）T: Noise pollution is not easily defined. Part of the difficulty lies in the fact that in some ways it is different from other forms of pollution. Noise is transient;once the pollution stops, the environment is free of it. This is not the case for chemicals, sewage, and other pollutants introduced into the air, soil, or water.The definition of noise itself is highly subjective. To some people the roar of an engine is satisfying or thrilling; to others it is an annoyance. Loud music may be enjoyable or a torment, depending on the listener and the circumstances.Broadly speaking, any form of unwelcome sound is noise pollution, whether it is the roar of a jet plane overhead or the sound of a barking dog a block away. Deal with Ex 3.Ask students to read the 10 statements. Try to predict the information that is missing. Then listen to the radio programme and complete the notes with one or two words.

S3: The last five statements.T: Right! Now let’s read the bad e ffects caused by noise....Deal with Ex4.T: Now that noise has so many negative effects on us, it is necessary to control noise.
