问题 After years of research, scientists have ______ the virus that is responsible for the disease.

选项 A、recognized
B、identified
C、guaranteed
D、notified

答案 B

解析 语义连贯题。[A]“认出,承认”;[B]“确定,识别”,强调经过了一个过程才确定;[C]“保证,担保”;[D]“通知,宣告”。题干中的years of research(数年研究)提示科学家最终得到了结果,虽然这个过程漫长,但最终还是确定了这种病毒,[B]符合题意,是答案。
