[00:00.98]Exercise 4 Listen to the scond part of [00:04.22]the radio programme.Take notes on the following [00:08.05]So,it's very important to control noise [00:10.78]pollution, isn't it? [00:11.81]That's right.As I said, [00:13.38]noise pollution is unpleasant for us all. [00:16.52]It can cause stress and loss of sleep [00:19.18]and can also damage our hearing. [00:21.97]Take car horns for example. [00:24.87]Experts say that only 40 minutes [00:27.61]of exposure to a car horn would damage our [00:30.61]hearing permanently.So you see, [00:33.26]noise pollution really can affect [00:35.45]people's lives. [00:37.00]How can noise pollution be controlled? [00:39.52]Actualy,noise pollution isn't hard to control. [00:42.73]There are some relatively simple methods [00:44.97]that the government has started using [00:47.16]to reduce noise pollution in our cities. [00:49.89]For example, there are plans to improves public [00:53.12]transport so that the number of cars [00:55.61]on the roads will be reduced. [00:57.71]There are also plans to install soundproof [01:00.95]windows in buildings which face onto roads. [01:04.52]Another way to reduce noise pollution [01:07.04]is to build main roads, [01:08.62]industrial areas and shopping malls [01:11.06]away from places like schools, [01:13.04]hospitals and residential areas [01:15.90]where people need peace and quiet.
