Is Fresh Air Really Good for You?

We all grew up hearing people tell us to “go out and get some fresh air.” __1__ According to recent studies, the answer is a big YES, if the air quality in your camping area is good.

__2__ If the air you're breathing is clean—which it would be if you're away from the smog of cities—then the air is filled with lifegiving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles (肌肉) and your brain.

Recently, people have begun studying the connection between the natural world and healing (治癒). __3__ In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood (情緒). Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see Buildings or sky instead. __4__ It gives us a great feeling of peace.

__5__ While the sun's rays can age and harm our skin, they also give us beneficial Vitamin D. To make sure you get enough Vitamin D—but still protect your skin—put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that's plenty of time for your skin to absorb a day's worth of Vitamin D.

A．Fresh air cleans our lungs.

B．So what are you waiting for?

C．Being in nature refreshes us.

D．Another side benefit of getting fresh air is sunlight.

E．But is fresh air really as good for you as your mother always said?

F．Just as importantly, we tend to associate fresh air with health care.

G．All across the country, recovery centers have begun building Healing Gardens.

【回答】

篇章導讀：本文是一篇説明文，介紹了呼吸新鮮空氣和接近大自然有益於身心健康。

1．E　空格前一句句意：我們都是聽着人們説的“出去呼吸點兒新鮮空氣”長大的，空格後一句句意：根據最近的研究，*是肯定的。由此可判斷E項“但是新鮮空氣真的像你媽媽總説的那樣對你有好處嗎？”符合語境。

2．A　空格處為本段的中心句。根據空格後的內容可知，如果人們呼吸的空氣是乾淨的，那麼空氣中就充滿了維持生命的、讓人充滿活力的氧氣。如果在户外鍛鍊，人的身體會學會深呼吸，讓更多的氧氣進入肌肉和大腦。所以本段主要説明了呼吸新鮮空氣的好處，故A項“新鮮空氣清潔我們的肺”符合語境。

3．G　空格後的“these places”與G項中的“recovery centers”相呼應，因此G項“全國各地的康復中心已經開始建造康復花園”符合語境。
