would have been declared a national treasure if he had not chosen to take up Canadian citizenship last year 我想问一下would have done...had done?的语法是什么意思&这句准确的翻译?
答
“如果他去年没有选择取得加拿大国籍的话,他就会被封为国宝了.” 这句是虚拟语气.if 后面的句子是假设（事实上并没有发生）,如果是正常的（非虚拟语气）句子则是he didn't choose to take up Canadian citizenship last year,这里由于是虚拟语气假设,时态上倒退一个时态,即did not choose变为had not chosen.主句的虚拟语气用would + 完成时态.
