Question

4．I'd appreciate ________ if you could let me know in advance whether or not you will come．（　　）

• A． it
• B． you
• C． one
• D． this

Answer 1

分析 如果你提前让我知道你是否会来，我会非常感激的．

解答 答案A．
it指代if从句所表述的内容，是充当形式宾语．真正的宾语是：if you could let me know in advance whether or not you will come． I'd appreciate it if…属于固定句式，表示"假如…我将不胜感激"．故选A．

点评 考查代词辨析及语境理解．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．We really appreciate it when she offered to help．她来帮忙了，我们十分感激．
