【语篇解读】这是一篇说明文。文章介绍了新鲜空气的好处：新鲜空气中的氧气，阳光对人们的身心健康均有好处。人们已经开始利用大自然和治愈疾病的关系，建造“康复花园”，治疗病人了。
36.E
根据下一句中的“the answer is a big YES”可知，该空应该是一个一般疑问句，选项中只有E选项是一般疑问句。故选E：但是新鲜空气真得像你母亲说的那样对你有好处吗？空前的people tell us to “go out and get some fresh air”和选项中的“your mother always said”亦是呼应。
37.A
根据下一句中提到的“If the air you’re breathing is clean…the air is filled with life-giving, energizing oxygen”可知，新鲜空气充满赋予人生命的，充满活力的氧气。下文中“…breathe more deeply, allowing more oxygen to get to your muscles and your brain”是对前文的递进：在户外，更多的氧气进入你的肌肉和大脑。根据前面的分析可以推知，该空应该提到新鲜空气的基本作用，根据常识，我们知道吸入的空气首先进入的是肺部，然后才会使我们的肌肉和大脑受益，故该空应选A选项：新鲜空气清洁我们的肺部。
38.G
根据下一句中提到的“these places”可以推知，该空应该提到表示地点的复数名词。选项中只有G选项提到该类名词，故选项G：在全国，康复中心已经开始建造“康复花园”。these places就是指Healing Gardens。
39.C
前文介绍的是“康复花园”中的绿色植物对于病人康复的好的作用：绿色的正在成长的植物可以减轻压力，降低血压，使人情绪良好。空后提到“它给我们一种平和感”。该空起承上启下的作用，仍然要提到处于“康复花园”这种自然环境中的好处，空后的it也要指代这种情况。故C选项切题：身处大自然可以使人精神焕发。
40.D
根据下文中提到的“the sun’s rays…give us beneficial Vitamin D”可知，该段介绍的阳光的好处。故该选项应该提到阳光。选项中只有D选项涉及阳光。故选D：获得新鲜空气的另一个好处是阳光。
