单选题 The people of this new African country all treasure their ______ independence and are determined to build their country into a land of prosperity.

A、 hard-nosed
B、 hard-pressed
C、 hard-won
D、 hard-boiled

【正确答案】 C

【答案解析】[解析] 形近词辨析。选项中的形容词均以hard-开头，但词义不同。hard-nosed“顽固的；精明的”；hard-pressed“被紧紧催逼的”；hard-won“来之不易的；难得的”；hard-boiled“煮过熟了的；不动感情的”。根据句中new African country，prosperity提供的语境，空格应填入褒义词。选项中，只有hard-won符合要求。故答案为C。
