Such sustained losses in terms of trade have contributed to growth performance in West Africa that is poorer than in East and South Africa.
A、undestroyable
B、remarkable
C、unusual
D、continuous
【正确答案】:D
【名师解析】:题目中的关键词 "sustained" 意味着持续的、持久的。选项A "undestroyable" 意为不可摧毁的,选项B "remarkable" 意为非凡的或显著的,选项C "unusual" 意为不寻常的,而选项D "continuous" 意为连续不断的。根据题目内容,提到了贸易损失是持续的,这影响了西非的增长表现,使其比东非和南非更差。因此,正确答案是选项D "continuous",因为它与题目中的 "sustained" 意思相符,表示贸易损失是连续不断的,导致了西非的增长表现不佳。
