谜底：C。意为固然她很年老，却晓得良多。
2)as, though指导的倒装句
as / though指导的让步从句必需表语或状语提早（描述词、副词、分词、实义动词提早）。
Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
留意： a.句首名词不能带任何冠词。
b.句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一同放在主语之前。

固然他尽了勉力，但他的义务总做的不尽人意。

Whatever happened, he would not mind.
更换：no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever

留意：no matter不能指导主语从句和宾语从句。

（对）Whatever you say is of no use now.
你现在说什么也没用了。(Whatever you say是主语从句)
