题目

_____ your advice yesterday,I could complete the task tomorrow.为什么
_____ your advice yesterday,I could complete the task tomorrow.
选项:
a、Did I taken
b、Should I taken
c、Had I taken
d、Were I to taken

答案

C,虚拟语态的倒装结构.
如果我昨天听从了你的建议,我明天将会完成这项任务.
这句话应该是If I had taken your advice yesterday,I could complete the task tomorrow,但有时可以把含有助动词、情态动词、be或have的虚拟条件句中的连词if 省去,而将had ,should,were 等词提到主语之前,即用倒装结构,
而A,B,D选项,后面的动词应该用动词原形take,所以都排除了.
C选项,表示应该做而没做.
