[单项选择][听力原文] ??清晨,空气新鲜,大气层中含有较多的氧气。中老年人应该到绿地或公园中进行呼吸养生。呼吸养生的正确姿势是:挺身直立,目光远视,两手叉在腰间,双肩松弛,胸部自然舒展;接着,用双手向自己的肚脐方向用力推挤,同时通过鼻腔深深地吸气;然后再从口中缓缓吐出,双手收回到腰部。呼吸养生的关键在于吸气、呼气要尽量缓慢,如果平时一呼一吸需要5秒钟,那么进行呼吸养生时就需要10秒钟。像这样每天做上40-60次,不间断,就可以使肌体得到较多的氧气,从而刺激心、脑、肝、肾等重要脏器的组织细胞,维持正常的新陈代谢,使青春常驻。 清晨,中老年人应该到绿地或公园中做什么?()

25Swiss voters overwhelmingly rejected a nationwide referendum Sunday that would have set the nation’s minimum wage at $25 an hour and 22created the world’s highest paid unskilled workforce.
Final results from Sunday’s vote showed 76.3% of voters opposed the Decent Salary Initiative, which would have had the greatest impact on 23immigrants working in such jobs as agriculture, housekeeping and catering.
