commerce 是不可数名词，指「大规模的商业贸易活动」，比 trade 更正式。关键搭配：commerce and industry（商业与工业）；chamber of commerce（商会）；e-commerce / electronic commerce（电子商务）；international / global commerce（国际/全球商业）；a commerce degree（商学学位）。形容词：commercial（商业的：commercial success = 商业成功；commercial airline = 商业航空；commercial interests = 商业利益）。辨析：commerce（大规模商业活动，较书面正式）vs. trade（贸易，可与 commerce 互换，但 trade 更具体：free trade = 自由贸易）vs. business（商业/生意，最广泛常用：do business = 做生意）。
