12. A考查非真实条件句的虚拟语气。句意：要不是我们学校的捐款，这个男孩儿的父母上周不可能付清手术费。根据句中已知的时间状语last week，可排除B、D。而couldn't have
paid for意为"不可能付 "；shouldn't have paid for意为"本不应该付……"。根据句意可知选A。
【拓展延伸】要不是：（l)but for...(介词短语，与过去或现在事实相反）
(2)had it not been for ... = if it hadn't been for ...(与过去事实相反）
(3)were it not for... = if it were not for ...(与现在事实相反）
