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 (治愈). __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 (情绪). 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】

篇章导读：本文是一篇说明文，介绍了呼吸新鲜空气和接近大自然有益于身心健康。

1．E　空格前一句句意：我们都是听着人们说的“出去呼吸点儿新鲜空气”长大的，空格后一句句意：根据最近的研究，*是肯定的。由此可判断E项“但是新鲜空气真的像你妈妈总说的那样对你有好处吗？”符合语境。

2．A　空格处为本段的中心句。根据空格后的内容可知，如果人们呼吸的空气是干净的，那么空气中就充满了维持生命的、让人充满活力的氧气。如果在户外锻炼，人的身体会学会深呼吸，让更多的氧气进入肌肉和大脑。所以本段主要说明了呼吸新鲜空气的好处，故A项“新鲜空气清洁我们的肺”符合语境。

3．G　空格后的“these places”与G项中的“recovery centers”相呼应，因此G项“全国各地的康复中心已经开始建造康复花园”符合语境。
