一道GMAT的SC题
One of Arthur Jessop’s first acts as president of the FHA was to deny a request from the private sector that federal home loan programs should be expanded to cover houses not conforming to civil construction codes.
(A) should be expanded to cover houses not conforming to
(B) be expanded to cover houses not conforming to
(C) should be expand to cover houses not conforming with
(D) would have been expanded to cover houses not conforming to
(E) had to be expanded to cover houses not conforming with
改句啊

答案

首先可以去掉选项E,had to be done结构复杂,不符合sc题简洁明确这一原则.同理可排除选项D.其次可以排除选项C 选项内部出错,should be 后应加done的形式,即expanded 而不是动词原形expand.由于that 指代的是request,后面是陈述request的内容,所以情态动词should多余.因此A选项也可排除.
所以答案为选项B be expanded to cover houses not conforming to
句子简洁,语义明确.
