34、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给予人生命的、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。所以本段落主要说的是呼吸新鲜空气的好处。故C项“新鲜空气清洁我们的肺”符合语境。 3.G空格后的theseplaces与G项中的recoverycentres相呼应,代入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。 4.C空格前介绍了接近大自然、看绿色植物对病人的康复有益,空格后一句说“它给我们一种内心平和的感觉”,由此可推断出空格处应该表达置身于大自然的好处,故选C项“置身于大自然使我们精神焕发”。 5.D空格后一句说,虽然阳光会老化和伤害我们的皮肤,但它们也能带来有益的维生素D。这应该是呼吸新鲜空气附带的好处,故D项“呼吸新鲜空气的附带好处是获得阳光”符合语境,D项中的sunlight与空格后的thesunsrays相呼应。
