Question

She is the only one of the girls in our class______ been to the United            States. 

A．who have

B．that had

C．whom has

D．that has

Answer 1

D

考查定語(yǔ)從句和主謂一致。本句的先行詞是the only one，是單數(shù)，故定語(yǔ)從句的謂語(yǔ)用單數(shù)，根據(jù)is可知，時(shí)態(tài)是現(xiàn)在時(shí)，排除A、B；先行詞指的是人，且作主語(yǔ)，故用who/that。故選D。
