二、阅读理解 让身体饱尝阳光
素养:思维品质 难度:中 用时:8 分钟
[2025 河南中考] Sunshine does make people happier. Imagine how cheerful you are when it clears up after long cold rainy days. Let's discover science behind sunlight.

Sunlight causes you to produce a chemical (化学物质) called serotonin (血清素). When you are exposed to sunlight, your body will make more serotonin. Higher levels of serotonin will keep you in good spirits. At night, when there is little or no light, your body produces another chemical — melatonin (褪黑激素). It helps your body relax and will make you feel tired, which can prepare you for a good night's sleep. You should keep a good balance between these two chemicals.
However, for many people, it is hard to balance sunlight with darkness. People who stay indoors a lot may not get enough sunlight. The light in a house is usually about 100 times less than that outside on a sunny day. That's why it is believed that those people should get outside in the sunshine. They can get some exercise, enjoy the fresh air and be happy, all at the same time.
There are places where it gets dark for a long time in winter. People in those places are easier to get seasonal affective disorder (SAD). People with SAD usually go through bad experiences such as low energy and sadness. The most common treatment for those people is to sit under bright artificial (人工的) lights for some time.
The roles that sunshine plays in people's life are more than those above. For example, your body produces vitamin D (维生素 D) from sunlight, which is important for being healthy. In fact, there is more science about sunlight for you to discover. So next time, when you notice the sunshine on your shoulder, take a moment to think, "Why do we love sunshine?"
1. Which of the following can take the place of "are exposed to" in the passage?
A. stay in
B. care about
C. dream of
D. depend on
2. What does Paragraph 2 mainly talk about?
A. What can help people to keep in good spirits.
B. How light influences people through chemicals.
C. Why melatonin can help people relax for a sleep.
D. Which chemical is thought to be more important.
3. [新考法·创新性设问] Which of the following is an opinion according to the passage?
A. There are places where it gets dark for a long time in winter.
B. People who stay indoors a lot should get outside in the sunshine.
C. The light in a house is usually less than that outside on a sunny day.
D. People's bodies produce something called vitamin D from sunlight.
4. Jack is a person with SAD. How could he solve his problem according to the passage?
A. By staying indoors a lot.
B. By taking in more fresh air.
C. By doing some exercise.
D. By using man-made lights.
5. Why is the sentence "Why do we love sunshine?" written in the last paragraph?
A. To encourage readers to learn more about sunlight.
B. To advise readers to stay in houses for enough time.
C. To let readers realize the importance of vitamin D.
D. To invite readers to walk into nature to enjoy the fresh air.

阅读提升
(1)clear up转晴;放晴;变晴朗

线索2:画线词后的“your body will make more serotonin”(你的身体会分泌更多的血清素)
结论:“are exposed to sunlight”表示“处于/待在阳光下”。故选A。
2.B 段落大意题。第二段的句意梳理:
第1~3句 阳光促使人体分泌血清素,使人保持愉悦心情
第4~5句 黑暗环境促使褪黑激素分泌,帮助人们放松及入睡
第6句 强调需要保持这两种化学物质的平衡
结合上面的分析可知,本段主要介绍了光是如何通过化学物质影响人的(状态的)。
3.B 推理判断题。
选项 句意 所属类别
A 在冬季,有些地区会长期处于黑暗中。 地理事实
B 经常待在室内的人应该到户外晒太阳。 “应该”表明是建议、主张,属于观点

结合以上分析可知,只有B项属于观点。
4.D 细节理解题。根据第四段中的“People with SAD...The most common treatment for those people is to sit under bright artificial(人工的)lights for some time”可知,对应D项中的“man-made lights”应选D。
5.A 推理判断题。题目问的是作者在文章最后一段写“Why do we love sunshine?”的目的。该题需要结合全文主旨和结尾段功能作答。
选项对比
A.为了鼓励读者更深入地了解阳光。(√)
文章主要介绍了阳光对人们的影响,且最后一段提到“The roles that sunshine plays in people’s life are more than those above”和“there is more science about sunlight for you to discover”,由此可推知,A项符合题意。
B.为了建议读者在室内停留足够长的时间。(×)
全文主张多接触阳光,且第三段明确提出常居室内的弊端。
C.为了让读者意识到维生素D的重要性。(×)
文章虽提到了维生素D,但仅是为了说明阳光的重要性。

本文旨在介绍阳光对人的益处,文中也隐含鼓励人们走进大自然的信息,其核心目的是使人们多接触阳光,而非呼吸新鲜空气。
