解析
试题分析:情景对话 句意为:--这片湖闻着咋这么难闻呢? --因为大片的水都被污染了 从语态上讲,动词有主动和被动之分;如果主语和谓语动词之间是主动关系,则为主动语态,反之,则为被动语态。根据答语,主语为water,谓语为pollute,显然为被动关系,可排除A.从时态角度讲,此题涉及进行时和完成时,根据答语可知,水被污染这件事造成了湖被污染,产生了影响,这是现在完成时的用法。据此,可排除B.从主语和谓语一致关系看,通常情况下,不可数名词后跟单数谓语,不过前面有large quantities of修饰时,谓语需要复数形式,推出答案D 点评:此题属于较难语法题。主要考察考生对动词时态和语态和主谓一致的掌握程度和熟练情况,作答此类题型,可用排除法,将明显错误的选项排除。 |
