27. Even at present, in South Africa ______.
C
[解析] 根据Excerpt 3中的“Even today, the economic running of South Africa's gold mines depends largely on the employment of black laborers who are paid about 40 pounds a month, plus room and board, and who must work in conditions that can only be described as cruel.”可知,即使今天,南非金矿的经营主要也是靠雇用黑人劳工,包食宿,每月付大约40英镑,工人必须工作在只能用悲惨来形容的环境中。C项与题干所问的当前南非的情况相符。
