【正确答案】
Noise can be harmful to people. As the population grows, we experience an increasing use of all kinds of machines, such as automobiles, televisions and stereos. These things and many others that seem to benefit people a lot may turn out to be a source of noise pollution. Nowadays noise pollution is getting so serious that people all over the world are paying greater attention to it and seeking ways to deal with the problem.
Noise does harm to people physically. Studies have proved that long exposure to noise intensity will lead to the loss of hearing. It also does great harm to people who suffer from heart trouble. So there is a widespread concern over the noise pollution. Moreover, noise also disturbs people's mind. Some of the work sites make a lot of noise at night, leaving people in a sleepless state. Noise from a stereo and television or things like that can be annoying. It may drive people "mad" and give rise to quarrels among neighbors.
Now more people realize that silence is a natural resource and must be protected by law. Research findings show that while we all find company in sound, in the meanwhile we all need a little silence from time to time.

【答案解析】[提示] 本题主题为一个严重的社会问题：噪音污染。画面上的两个人为来自四面八方的噪声所困扰，无处可躲，狼狈不堪。在构思阶段，应按题目要求，归纳出所有能想到的、与噪声污染有关的现状、危害、成因、治理等事实与观点。噪音对人的生理和心理都有很大危害，画面上描绘的主要是生活噪音，如果按照这个思路写，便可增加因噪声扰民带来的邻里关系问题；也可以扩展到其他类型的噪音对人们的负面影响，那么就可以列举工地施工、汽车鸣笛、清晨狗叫、街头秧歌队等噪音。写作文的一个大忌是内容一般化或雷同，要想避免这个缺点，就应充分利用构思阶段开阔思路，找出别人可能想不到的内容，形成自己的亮点。
