In cold weather, people spend more time inside. Colds and flu are common. We have a cold or catch a flu more easily inside. But they're not the only winter health risks.
Many people report feeling more tired and sad in winter. This is called the winter blues. What causes the winter blues? To find out, we spoke to a doctor who treats kids. Your health need more attention in the winter months.
Sunlight is important to our health and well-being. It helps our bodies make vitamin D. Vitamin D strengthens our immune system (免疫系统). It helps make our bones stronger and healthier. And it may help when we're feeling down. Being in the sun can also make us feel happy. "The sun tells our brain to send a special chemical to our bodies," Dr Dovico says. "It's called serotonin. That is what puts us in a good mood."
★ fights the winter blues. In the winter, the days are shorter. There's less sunshine. It can be too cold to go outside. Less sun means less serotonin and vitamin D. But don't worry. There are ways to deal with the winter blues. "Try to spend time playing and having fun outside even if it is cold," Dr Dovico advises. "Be sure to wear enough clothes. But come in if you get too cold!" Even 15 minutes of sun can make a difference.
If you can't get sun, find things you enjoy inside. You can read a book or play games. Do an art project. Get together with a friend or do anything you enjoy indoors.
Feeling blue? You're not alone. It's reported that nearly 4 in 10 people feel in low spirits in winter. It's normal to feel the winter blues. But if you can't beat them, just talk to a person you believe in about how you feel.

【分析】
1. 第61题：要确定“the winter blues”的含义，需在原文中找对应的定义描述。根据第二段开头“Many people report feeling more tired and sad in winter. This is called the winter blues.”，直接能找到该短语的指代内容，对应选项即可。
2. 第62题：判断第三段回答的问题，需梳理段落主旨。第三段开篇点明“Sunlight is important to our health and well-being.”，随后具体阐述阳光帮助身体合成维生素D、增强免疫系统、改善情绪等作用，都是在解释阳光对健康重要的原因，据此匹配选项。
3. 第63题：需根据上下文内容推断★处的句子。第四段主要讲对抗冬季抑郁的方法，后文提到冬季日照短，建议即使天冷也要出去晒太阳，15分钟就有作用，所以★处应是引出“晒太阳”这个方法的主题句，对应选项。
4. 第64题：根据题干Dr Dovico和sunlight exposure的关键词，定位到第四段末尾“Even 15 minutes of sun can make a difference.”，直接获取时间信息。
5. 第65题：第五段列举了不能晒太阳时对抗冬季抑郁的活动，包括读书、做艺术项目、和朋友相聚等，对比选项，找出不在列举范围内的活动。
