鲁教版（2024）七年级英语上册Unit 7 Avoid Danger,Keep safe 测试题 一、阅读理解 A Do you often listen to music at loud volume (音量) You should know it is bad for your hearing, according to the World Health Organization(WHO). Many young people are at risk of hearing loss because they listen to loud noise for a long time, WHO said. Listening to music or watching a TV show at loud volume can harm your hearing. The United Nations has standards (标准) for safe listening . It is not safe to listen to sounds that are louder than 85 decibels(dB 分贝) for eight hours or 100 dB for 15 minutes. The sound of a busy road is about 85 dB and the sound of a rock concert can be about 100 dB. Loud noise is harmful to the inner ear. Most of us are born with about 16,000 hair cells(毛细胞） in our inner ears. These cells detect(探测) sounds . However, listening to loud noise for a long time can make these cells work too hard and cause some of them to die. This is what causes hearing loss. Some people might think that their music isn’t all that loud . But this can depend on where you are. For example, if you are in a noisy place like the subway, you might turn up your music too loud. Later, when you listen to it at the same volume in a quiet place, you might feel uncomfortable. WHO said the “safe level” for most sounds is below 80 dB for up to 40 hours a week. A level of 80 dB is roughly equal to the noise of a subway. ( )1.How does the writer begin the text A. By asking a question. B.By telling stories. C.By giving examples. D.By giving reasons.
