五、(2025·苏州)阅读表达。
Every day, we hear sounds all around us—some soft, some loud. But do you know that loud sounds can harm your hearing?
Sounds are measured(测量) in decibels(分贝). Look at the chart—some sounds are safe for our ears, but when a sound goes over 85 decibels, it can be harmful to our hearing. To reduce the risk of hearing loss, we shall pay attention to the loudness of the noise, the distance we are to it and how long we listen to it.
Noise levels can be measured by sound-level meters(噪声计), but you probably don't always carry one with you. So how can you tell whether noises are too loud or not? Ask yourself: Do you have to raise your voice to be heard? Do you find it hard to hear someone about a metre away from you? Do the noises make your ears hurt or ring for some time? If your answer is YES to any of these, that probably means the noises are too loud.
Headphones are especially tricky. Many people enjoy using them, but they often listen to loud music for too long, or keep the volume(音量) so high that even other people can hear the noise from their headphones. These can lead to hearing loss.
Your hearing is a gift. You need it for learning, communicating and enjoying the world. Once your hearing is harmed, it may never come back.
1. According to the chart, what sounds can harm your hearing?
2. How can you know if the noises are too loud? (Give 2 examples.)
3. 新考法 开放性设问 Why is hearing important? What can you do to protect it?
