日常生活中,有美妙的声音。如,歌声、乐曲声、鸟鸣等等。这些好听的声音可以使人愉悦,有益健康。与此相反,还有一些使人厌烦的、对人的日常生活起干扰作用的、很难听的声音。如,巨大的撞击声、大型机器的轰鸣声、以及车马的喧嚣(xiao)声等等。这些声音就是人们常说的噪(zao)音。噪音会造成环境污染,对身体是有害的,我们应当远离它。 In everyday life, there is a wonderful voice. Such as singing, music, birds singing and so on. These nice sounds can make people happy and healthy. On the other hand, there are some annoying, unpleasant sounds that interfere with people's daily lives. For example, a huge percussion, the roar of large machines, as well as the hustle and bustle (xiao) sound and so on. These sounds are what people often call zao sounds. Noise can cause environmental pollution and is harmful to our health. We should stay away from it.
