My father asked him_____ Awhy to do B what he did it for C what to do it Dhow he did with it
答
B what he did it for
答
B what he did it for
答
选B.
A应该是why to do it
B等于why he did it
C应该是how to do it
D应该是how he did it
答
B. what he did it for
答
此题应选D
楼上选B,我有异议.因为若选B,what应该是充当did的宾语,而B项中did已有宾语it, 故did有两个宾语,一个是what,一个是it,二者重复.排除C的理由也是如此,do有两个宾语,重复.
