For years, no one could make this particular therapy work in animals larger than rodents, but two research groups have demonstrated its______in dogs.
选项
A、efficacy
B、energy
C、enormity
D、exclusion
答案
A
解析
(1)句子结构。
本句是一个由but连接的并列句:前一个分句的主语为no one,谓语为could make,宾语为this particular therapy,宾语补语为work,之后的介词词组in animals…作状语;后一个分句的主语为two research groups,谓语为have demonstrated,宾语为its in dogs。
(2)选项词义。
A.efficacy n.功效;效力
B.energy n.[物]能量:活力;精力;精神
C.enormity n.穷凶极恶;弥天大罪;巨大;极大
D.exclusion n.拒绝,杜绝;排除,驱逐;被排斥在外的人(或事物)
本句大意为“多年来,没有人能成功将这种疗法应用于比啮齿动物更大的动物,但是两个研究小组已经证明这种疗法对狗有效”。从上下文来看,make…work大意基本等同于efficacy,因此,只有选项A最符合题意。
