谁能帮我看一下这句英语有没有错误
I'd buy this if it were cheaper.再便宜一点我就买.（这是我在爱词霸看到的,it是单数不是应该配is吗,就算是过去式应该也要配was吧.可是这里为什么用were 这句话有没有错误呢?
答
没错，were是表示虚拟语气，就像说“如果我是你”就是“if i were you”不能单纯的从谓语动词的角度理解，详细的就看语法书虚拟语气部分吧
答
是if条件句的虚拟语气，这句话是对现在的虚拟，if从句用一般过去时，be动词用were，主句用将来时（此句中是would）
答
没有错误，这句是虚拟语气，在虚拟语气中不管单复数或者现在将来，全部是were
答
没有错误，这是虚拟句，在虚拟语句中，这是固定用法，一定用were
答
是假设现在,书面用法If he were French,he would live in Paris.If she were rich,she would buy a yacht.I would play basketball if I were taller.I would buy that computer if it were cheaper口语可用 was...
