Question

Not until many years later_______that many of his neighbors helped him when he suffered the loss of his parents at an early age.

A.he was informed B.he informed

C.was he informed D.did he informed

Answer

C

【解析】

考查倒装和时态。句意：直到很多年后，他才得知，当他年幼失去父母时，许多邻居帮助了他。Not until+从句/词组置于句首时，全句用部分倒装，即：Not until+从句/词组+助动词/be动词/情态动词+主语+其它，所以排除选项A和B；根据时间状语 at an early age可知用一般过去时。因为他是被告知，所以此处需用被动he was informed，否定词置于句首，倒装，be动词was提至主语he前。故选C。
