A.when does his son come homeB.when did his son come home
C.when his son comes homeD.when his son came home

分析 King先生不知道他兒子昨天晚上什么時(shí)候回家的.

解答 答案:D,考查賓語從句:句意"King先生不知道他兒子昨天晚上什么時(shí)候回家的.".賓語從句中從句部分要用陳述語序(主語在前,謂語在后),因此A,B不正確.根據(jù)didn't可知主句是一般過去時(shí)態(tài),因此從句也要用一般過去時(shí)態(tài).C是一般現(xiàn)在時(shí)態(tài),不正確.答案是D.

點(diǎn)評(píng) 賓語從句中從句通常用陳述語序,即"連接詞+主語+謂語+其它",主句是一般現(xiàn)在時(shí)態(tài)或一般將來時(shí)態(tài),從句時(shí)態(tài)不受限制.主句是一般過去時(shí)態(tài),從句用一般過去時(shí)態(tài),注意根據(jù)語境完成試題.
