题目内容
2.I don't know _______ her because I forget the arrival time of her flight.( )| A. | where to meet | B. | how to meet | C. | when I to meet | D. | when to meet |
分析 我不知道什么时候去接她因为我忘了她的航班到达的时间.
解答 答案:D.know后加宾语,疑问词+to do作为宾语,结合 because I forget the arrival time of her flight可知不知道什么时候,故when,故答案是D.
点评 动词不定式可跟在what,how,where,which,when等疑问词(why除外)之后,构成"疑问词+to do"结构.
此结构常放在know,ask,find out,forget,decide等动词后作宾语.例如:
We must know what to say at a meeting.
我们必须知道在会议上说什么.
He could not tell whom to trust.
他不能区分该相信谁.
