题目内容
15．---Do you know _______？---Sorry，I have no idea．（ ）
| A． | where did you park my car | |
| B． | what's the matter with him | |
| C． | how can I get to the park | |
| D． | when they have finished the work |
分析 --你知道他怎么了？
--对不起，我不知道．
解答 答案：B
根据题干Do you know及选项知此题考查宾语从句．
首先，根据宾语从句必须为陈述语序，排除选项A，C；
再根据答语Sorry，I have no idea（对不起，我不知道）可推知上文询问的为某件事．此处做宾语从句，使用陈述语序，且之前主句为do you know一般现在时，从句可根据自身情况选择合适的时态，选项D为问什么时候完成工作，通常不与现在完成时连用，应为一般过去时或一般将来时，可排除．选项B为一般现在时，符合句意，且本身为陈述语序，故选B．
点评 此题考查宾语从句必须用陈述语序及根据句意选择合适的引导词．其中B，D选项的区分是本题的难点．
