選D.
know后面接的從句是做know的賓語,賓語從句的結構：疑問詞+陳述句.
1.A和C都是特殊疑問句,不能做know的賓語從句.
2.只能在B和D中選,由于主句的謂語didn't是過去時,而從句B中的comes是一般現(xiàn)在時,因而時態(tài)不一致.
3.所以D.
Mr.Wang didn’t know ________________ yesterday evening.
Mr.Wang didn’t know ________________ yesterday evening.
A.when does his son come here B.when his son comes here
C.when did his sin come here D.when his son came here選C嗎?
A.when does his son come here B.when his son comes here
C.when did his sin come here D.when his son came here選C嗎?
