Question

过去完成时had➕v过去分词的句子？

Answer 1

回答如下：
顾名思义，过去完成时指过去的过去，即其动作在过去某一动作之前发生，或在过去某一时间之前发生。它的结构是助动词had + 过去分词。过去完成时不能单独使用，只能在和过去某一动作或过去某一时间对比时使用。例如：
( 误) He had worked here for two years.
(正) He had worked here for two years before you came here.
(正) He told us that he had worked here for two years.
( 正) He had worked here for two years by the end of last month.
( 正) He had worked here for two years by the time you came to work here last year.
(正) He had worked here for two years by then
