9、第一个题干是一个强调句型,特殊疑问句下的强调句型,有what引导;第二个空是对what的回答,因为what是上一句的主语,That she got the lowest mark in her class是从句,可以作主语;而D项的get是动词原形,不能作主语,故答案为C。【点评】考查强调句型的使用和对特殊疑问句的回答,注意问什么回答什么,也就是说疑问词what是句子的主语,回答的内容也需要在句子中能作主语。9Located between the 16th and the 18th floor, _ I call my “home” is more like a “birds nest”.A
