- 试题详情及答案解析
- I’d appreciate ___________ if you could let me know in advance whether or not you will come.
- 答案：D
- 试题分析：考查代词。 句意为：如果你提前让我知道你是否会来，我会非常感激的。appreciate后跟接if或when从句时，其后不直接跟if或when引导的从句，若语义上需要接这类从句，需借助it。如： I would appreciate it very much if you would help me with it.如果你能帮助我做这事，我会十分感激。，故选D项。
