29、】本文是一篇说明文。文章介绍了呼吸新鲜空气和接近大自然有益于身心健康。 1.E 空格前一句说我们都是听着别人告诉我们“出去呼吸点新鲜空气”长大的,空格后一句说这个答 案是肯定的。根据“the answer is a big YES”可判断空格处应该填一个一般疑问句,所以 E 项“但是新 鲜空气真的像你妈妈常说的那样对你有好处吗?”符合语境。 2.A 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

30、语境。 3.G 空格后的 these places 与 G项中的 recovery centres 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 the suns rays 相呼应。
