问题 Many experts on international affairs expressed concern that Trump’s unilateral approach to globalization and multilateral efforts in international relations would put US-China relations on a rocky and ______ path. However, most of them breathed a collective sigh of relief after Trump’s visit to Beijing.

选项 A、precarious
B、persistent
C、perspicacious
D、pertinacious

答案A

解析 本题考查形容词辨析。根据a rocky and______path可知,所填词与rocky修饰名词path,rocky意为“坎坷的、艰难的”,precarious(不确定的,不安全的)符合语义,故答案为[A]项。persistent意为“持续存在的,继续发生的”;perspicacious意为“敏锐的,有洞察力的”;pertinacious意为“坚定不移的,义无反顾的”。
