Do you know ?
A. whether has Susan gone to Africa
B. when Susan has gone to Africa
C. if Susan has gone to Africa
D. where Susan has gone to Africa
这里是考查宾语从句吗?如果我把Do you know 去掉选项似乎都成立,但是加上就很疑惑,不知道怎么排除。求指点。
Do you know ?
A. whether has Susan gone to Africa 名词性从句不倒装。倒装错误。
B. when Susan has gone to Africa 现在完成时不能和确切时间状语连用。时态错误。
C. if Susan has gone to Africa 正确答案。
D. where Susan has gone to Africa 已经有了地点to Africa, 用where为逻辑错误。
