单项选择题
How often have you queued for （） seems like hours at the booking office before you can get a train ticket
A. what
B. which
C. that
D. when
答案
参考答案：A
解析：
what此处是关系代词，引导名词性从句作介词宾语，for what seems like hours意为for a long time。全句的意思是：“你在售票处前排了似乎好几个小时才买到火车票，这种情况经常发生吗？”又如：I don’t care about money or about what people call position. 我不在意钱，也不在意人们所说的地位。
