---- If he_____ , he ______ that food.              
---- Luckily he was sent to the hospital immediately.

A．was warned; would not take	B．had been warned; would not have taken
C．would be warned; had not taken	D．would have been warned; had not taken

答案

B

解析

考查与过去事实相反的虚拟语气，其构成为if +主语+had done ,主句为would/could/might+ have done,根据句意如果他被警告的话，他就会不吃那种食物了。表示的是过去，所以选B。
