单选题 John told us that by the end of the year he and his wife together for thirty years.

A) would have been living
B) would have lived
C) would have been lived
D) will have been living

【正确答案】 A

【答案解析】[考点] 将来完成进行时
[解析] 将来完成进行时的构成为：主语+shall／will have been doing，表示动作从某一时间开始一直延续到将来某一时间，动作是否继续下去，要视上下文而定。这种时态常常和表现将来某一时间的状语连用。此句是主从复合句，从句时态要与主句保持一致，主句是过去时，所以从句谓语也要用过去时。故答案为A)。
[避错] would have lived为过去将来完成时形式，表示在过去将来某一时间以前发生的动作；would have been lived为过去将来完成时的被动形式；will have been living为将来完成进行时形式，一般不用在主句谓语为过去时态的宾语从句中。
