No sooner____the par ___in when they rang me up.a.did i have,handed    b.had i, handedchad i had,handed      d.i have had答案是c，为什么
回答：no sooner…than…/hardly (scarcely)…when…表示“一…，就…”，引导时间状语从句，主句须用过去完成时，从句用一般过去时。No sooner/ hardly (scarcely)位于句首，主句倒装。如：

He had no sooner been there than I told him about it . 

No sooner had he been here than I told him about it .
