[2025 江苏苏州中考]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 meter 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.

答案
1 TV and headphones, rock concerts, and fireworks. 根据“when a sound goes over 85 decibels, it can be harmful to our hearing”可知，超过85分贝的声音会损害听力，结合图表信息可知答案。
2 When/If I have to raise my voice to be heard; when/if I find it hard to hear someone about a meter away from me; when/if the noises make my ears hurt or ring for some time. 根据第三段可知，可通过是否需要提高音量交流、在一米外听别人说话是否困难、噪声是否使耳朵疼痛或耳鸣的方式判断噪声是否过大。任选其二回答即可。
3 Because we need it for learning, communicating, and enjoying the world. We should not use headphones for too long./We should keep away from the loud noises./We can turn down the music./We can use headphones less. 根据“Your hearing is a gift. You need it for learning, communicating, and enjoying the world.”可知，听力用于学习、交流和享受世界，所以对我们来说很重要。保护措施可结合文本内容，如避免长时间处于嘈杂环境、控制耳机音量和使用时长等。本题答案不唯一，言之有理且无语法错误即可。
