一场致命的严寒席卷大地,数百万人被告知,若必须外出,就要穿多层衣服。洋葱式分层穿衣法是指穿多件衣服,以便在寒冷的天气让身体舒适。每一层衣物都会形成一个隔热的空气袋,比只穿一件大夹克更能提供保护,而且分层穿衣法有助于带走皮肤上的汗水与湿气。无论天气有多冷,你到户外开始活动时,就可能会出汗。如果你穿的衣服有正确分层,就会感觉到身上的汗水消失。如果你觉得冷,就再加一件;若觉得热或汗湿了,就脱掉一件。
As a bout of bitter and deadly cold sweeps the earth,millions of people are being told to dress in layers if they must go outside.Layering means wearing multiple pieces of clothing to keep your body comfortable in cold weather.Each layer creates an insulating pocket of air that protects you better than just wearing a big jacket,and layering helps move sweat and moisture away from your skin.
