Fresh air is known to improve our mood. But recent research shows that “forest therapy (疗法)” is a powerful way to reduce feelings of sadness and worry. Forest therapy means spending time in a forest while paying full attention to your five senses. It is far more than a simple walk; you truly notice the sights, sounds, and smells around you. This practice helps you step away from daily stress.

Why is it so effective? Experts give several reasons. First, natural light in the forest helps your body clock work better. This improves your sleep and helps you relax. Second, nature does not require much mental effort. Unlike screens or city noise, it gives your brain a chance to rest. Third, the beauty of the forest can fill you with gratitude. Feeling grateful has been shown to reduce stress and improve mood. In short, nature gives our busy minds a much-needed break.

How can you practice forest therapy? First, make it a habit. Even a few minutes each day is better than a long walk once in a while. Second, turn off your phone and leave devices behind. This lets you fully enjoy nature. Third, bring a notebook. Write down what you see, hear, and feel — like birdsong or the smell of trees. This keeps you focused on the present. You don’t need a perfect forest; a local park with trees works just as well.

1.1. What is forest therapy?

A Walking quietly in a forest.

B Sleeping to reduce stress.

C Enjoying nature fully.

D A therapy requiring training.

解析：选C。C细节理解题。根据文章第一段“Forest therapy means spending time in a forest while paying full attention to your five senses. It is far more than a simple walk; you truly notice the sights, sounds, and smells around you.”可知，森林疗法并非单纯在森林散步，而是全身心调动五感、充分感受自然。A选项仅提及“在森林安静散步”，表述片面，不符合原文定义；B选项“睡觉减压”、D选项“需要专业训练的疗法”在文中无任何依据；C选项“充分享受自然”完美契合森林疗法的核心定义。故选C。

2.2. What does the underlined word “it” refer to in the text?

A Natural light.

B Nature.

C City noise.

D Forest therapy.

解析：选B。B词意指代题。画线词“it”所在句子为“Unlike screens or city noise, it gives your brain a chance to rest”。该句紧接在“Second, nature does not require much mental effort.”之后，对比屏幕和城市噪音，“it”指代的正是前一句的主语“nature”，表示自然可以让大脑得到休息。A选项自然光虽然在前文出现，但与本句无关；C选项城市噪音只是被对比的对象；D选项森林疗法是本段的主题，但此处具体给予大脑休息机会的应是自然本身。故选B。

3.3. What can we learn from Paragraph 3?

A A perfect forest is necessary.

B Writing helps stay in the moment.

C Long walks are more helpful.

D Phones are useful for recording.

解析：选B。B推理判断题。根据第三段“Write down what you see, hear, and feel — like birdsong or the smell of trees. This keeps you focused on the present.”可推知，记录自然中的所见所感能够帮助人们专注当下、沉浸当下。本段最后一句“You don’t need a perfect forest; a local park with trees works just as well.”说明无需完美的森林，排除A选项；文段提到“Even a few minutes each day is better than a long walk once in a while.”，说明每日短时体验优于偶尔长距离散步，排除C选项；文段明确要求“turn off your phone and leave devices behind”，手机会干扰体验，并非有用，排除D选项。故选B。

4.4. What does the writer think of forest therapy?

A Harmful.

B Useless.

C Helpful.

D Costly.

解析：选C。C观点态度题。通读全文及最后一段“Forest therapy is a simple, free way to calm your mind and make you feel better. Next time you feel stressed, just step outside... let nature help you.”可知，作者认为森林疗法简单、免费，能够平复心绪、改善心情、缓解压力，对人是有益的。A选项“有害的”、B选项“无用的”与作者态度完全相反，D选项“昂贵的”和文中“free（免费的）”相悖。故选C。

5.5. Which is the best title for the passage?

A The History of Forest Therapy

B Fresh Air Is Important for Health

C How to Take a Walk in the Woods

D A Simple Way to Lift Your Spirits

解析：选D。D主旨大意题。全文围绕森林疗法展开，首先介绍其定义，接着分析其缓解悲伤、焦虑、减压怡情的有效原因，最后讲解具体实践方法，核心主旨是介绍森林疗法这种简单有效的情绪调节方式。A选项“森林疗法的历史”，全文未提及任何历史相关内容，无中生有；B选项“新鲜空气对健康很重要”仅为文章开篇铺垫，并非核心主题；C选项“如何在林间散步”仅对应文章第三段部分内容，片面，无法概括全文；D选项“：一种振奋心情的简单方式”精准概括全文核心内容，适合作为文章标题。故选D。
