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?
TV, headphones, rock concerts and fireworks.

2. How can you know if the noises are too loud? (Give 2 examples. )
①When/If I have to raise my voice to be heard.②When/If I find it hard to hear someone about a metre away from me.③When/If the noises make my ears hurt or ring for some time.(任选两个作答即可)

3. 新考法 问 Why is hearing important? What can you do to protect it?
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.(答案不唯一,言之有理即可)

答案:1. TV, headphones, rock concerts and fireworks.
2. ①When/If I have to raise my voice to be heard.②When/If I find it hard to hear someone about a metre away from me.③When/If the noises make my ears hurt or ring for some time.(任选两个作答即可)

五、(2025·苏州)阅读表达。
每天,我们都会听到周围的声音——有些轻柔,有些响亮。但你知道响亮的声音会损害你的听力吗?
声音以分贝来计量。看看这个图表——有些声音对我们的耳朵是安全的,但当声音超过85分贝时,就会对我们的听力有害。为了降低听力损失的风险,我们应当关注噪音的响度、我们与噪音的距离以及我们听噪音的时长。
噪音水平可以用噪声计来测量,但你可能不会总是随身携带一个。那么你如何判断噪音是否太大呢?问问你自己:你必须提高嗓门才能被听到吗?你觉得很难听到离你大约一米远的人的声音吗?噪音会让你的耳朵疼痛或耳鸣一段时间吗?如果这些问题中任何一个你的回答是肯定的,那可能意味着噪音太大了。
耳机尤其 tricky(这里可理解为“ tricky”有“难对付的;棘手的”意思,结合语境可译为“让人难以把控” )。很多人喜欢使用它们,但他们经常长时间听 loud(响亮的)音乐,或者把音量调得很高,以至于其他人都能听到他们耳机里的噪音。这些都会导致听力损失。
你的听力是一份礼物。你需要它来学习、交流和享受这个世界。一旦你的听力受到损害,它可能永远无法恢复。
1. 根据图表,什么声音会损害你的听力?
电视、耳机、摇滚音乐会和烟花(的声音)。
2. 你如何知道噪音是否太大?(给出2个例子。)
①当/如果我必须提高嗓门才能被听到时。②当/如果我觉得很难听到离我大约一米远的人的声音时。③当/如果噪音会让我的耳朵疼痛或耳鸣一段时间时。(任选两个作答即可)
3. 新考法 开放性设问 为什么听力很重要?你能做些什么来保护它?
因为我们需要它来学习、交流和享受这个世界。我们不应该长时间使用耳机。/我们应该远离 loud(响亮的)噪音。/我们可以把音乐音量调低。/我们可以少用耳机。(答案不唯一,言之有理即可)
