Question

14.   he explained it to me did I make sense of what he said.

A. Hardly had     B.  Not until

C. Shortly after   D.  No sooner

Answer 1

14.   B考査倒装句。根据后面的倒装"…did I make sense of what he said."可知前面是否定词放在句首的部分倒装句， 排除C,而hardly和no sooner后面用倒装句，需要搭配when和than的从句，只有not until放在句首+从句，后面的主句部分倒装。句意：直到他向我解释了，我才理解他说的话。所以选B。
