3月5日，原云南红塔集团董事长、褚橙创始人褚时健离世，享年91岁。请看本报周五的报道：

One of China’s iconic entrepreneurs, Chu Shijian, died Tuesday, aged 91. Chu, who made his name by turning a small regional cigarette factory into a thriving national tobacco giant in the 1980s and 1990s, ended his days as the head of an orange-growing empire in a remote, mountainous area of southwestern China’s Yunnan Province. Chu Oranges are known throughout the country and still sell at a premium over competitors’ fruit.

In between his two successful business enterprises, Chu’s life was turbulent.

报道中的at a premium就是“以高昂的价格（因为优质、稀缺）”。例如：

People want organic foods, so Mary can sell her eggs at a premium.

因为人们想要有机食品，所以玛丽能高价出售她的鸡蛋。
