问题 Just imagine every smoker is to give up smoking for the sake of their own and others’ health.

选项 A、shall
B、will
C、ought to
D、were to

答案D

解析 答案是D。此句考查be动词were的虚拟式。也就是说,不管主语是什么人称,动词一律用were。该句表达了一种美好的愿望:“为了自己和他人的健康,所有的烟民都戒烟了。”这当然几乎是不可能发生的事情,所以其语气才使用了虚拟式。再以“Just imagine every citizen of the world were to refuse to use the internet…”一句为例,一般说来,跟随every citizen的be动词应该是单数的is或was,但因该句是个与现实对立的“虚拟式”,因此才会用were的形式来表示。值得注意的是,英语的“虚拟语气”是英语语法系统中占有相当位置的语法规则。再以“If you should succeed,everything would be alright.”和“If we missed the train,we should have to wait an hour for the next train.”两句为例。因为这两句均是对未来推测的条件句,因此will,shall和miss都用了过去时以证其“虚拟性”。除上述外,还有诸多形式的“虚拟式”的使用值得引起大家的注意。看看下面这几句:“It is strange that she should have behaved like this.”“Even though she were here.I should say the same thing.”“If it hadn’t been for his help,you should have failed the attempt.”,这些都是“虚拟式”语用案例。
