Are you using your headphones too much? Noise-cancelling headphones(降噪耳机) bring you a quiet world, but using them for too long might be bad for your brain, according to The New York Post.
Doctors from the UK's National Health Service (NHS) have seen more young people having ‘ear problems’. These problems include trouble understanding speech or needing words to watch videos. However, though their ears are healthy, it's their brains that are affected(被影响). This problem is known as auditory processing disorder (APD[听觉处理障碍]). People with APD can hear sounds but find it hard to understand them.
We hear different sounds at the same time. To understand the information we hear well, our brains need to choose the important sounds to listen to, and not to listen to useless information. That is why we can understand our friends when we talk even in a very noisy room. If we don't hear different kinds of sounds, we can lose this skill, said NHS doctors. Noise-cancelling headphones take away these different sounds, which might be a part of the problem because they make a “false environment”. This makes it easier for your brain, so it doesn't have to work very hard.
Noise travels in waves(波) through air and water. Noise-cancelling headphones stop these waves in two ways: One is to use things like special ear cups. The other is to use a microphone(麦克风) to cancel out noise with different sound waves.
This technology can be bad for your health if you use it too much. However, it is still helpful for people working in noisy places.
( )27. Why does the writer ask a question at the beginning?
A. To do a survey.

解析
【分析】
本题为英语阅读理解题，需结合原文细节、写作意图、主旨大意及文章出处逐一分析：
1. 第27题考查写作意图：开头用问句“Are you using your headphones too much?”，目的是吸引读者关注，而非做调查、展示场景或获取答案，故选B。
2. 第28题考查细节理解：定位原文第二段“People with APD can hear sounds but find it hard to understand them”，对应选项D；A与原文“though their ears are healthy”矛盾，B与“can hear sounds”矛盾，C无依据，排除。
3. 第29题考查主旨大意：文章先指出过度使用降噪耳机影响大脑（APD），说明技术原理，最后强调过度使用有害，核心是提醒正确使用降噪耳机，故选C；A、B、D均为片面内容，非主旨。
4. 第30题考查文章出处：文章围绕降噪耳机对健康的影响展开，属于健康与科技相关内容，对应“Science and Health”板块，故选B。
【解析】
27. 写作意图题：开头问句用于吸引读者兴趣，A（做调查）、C（展示场景）、D（获取答案）均不符合写作逻辑，答案为B。
28. 细节理解题：根据原文“People with APD can hear sounds but find it hard to understand them”，可知APD导致理解声音困难，A（由耳朵疾病引起）与原文“ears are healthy”矛盾，B（听不到声音）与“can hear sounds”矛盾，C无依据，答案为D。
29. 主旨大意题：文章重点说明过度使用降噪耳机对健康的影响，目的是提醒正确使用，A（耳朵问题建议）、B（耳机重要性）、D（技术原理）均为局部内容，答案为C。
30. 文章出处题：文章涉及健康问题与科技产品，对应“Science and Health”板块，A（音乐艺术）、C（人与自然）、D（仅科技）均不全面，答案为B。
【答案】
27.B 28.D 29.C 30.B
