问题
选择题
. I'd really appreciate ________ if you would turn off the lights before you leave.
A.you
B.that
C.as
D.it
答案
答案:D
题目分析: 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.
点评: it 的用法很广,注意归纳总结。
