I'd really appreciate ________ if you would turn off the lights before you leave.A.youB.thatC.asD.it

D解析试题分析: it 的用法。句意；如果你在离开之前会把灯关掉，我将不甚感激。appreciate,like,love,hate等表喜好，憎恨之类词后不能直接接从句，必须先补充it后再接从句。it表虚指，无实义。另外，一些动词短语也不能直接加从句，必须加it再接从句,如see to it that ,depend on it that 等.考点：考查it 的用法。点评: it 的用法很广，注意归纳总结。

我明天再问问老师，叫他解释下这个问题
