Tony wanted to know ________.
A. what had Father Christmas put in his stocking
B. when Father Christmas had put in his stocking
C. what Father Christmas had put in his stocking
D. where Father Christmas had put in his stocking
这里我选的 D，为什么是错的?
答案：C
put 是及物动词，需要宾语what。
Tony wanted to know what Father Christmas had put in his stocking.
【翻译】托尼想了解圣诞节老人在他的袜子里放了什么。
你选的D：
Tony wanted to know where had Father Christmas put in his stocking.
假如把in 去掉，语法正确。意思就是：
托尼想了解圣诞节老人把他的袜子放在哪儿了。
如此的话，符合圣诞的风俗吗？
