题目内容
11.Among the crises that face humans ________ the lack of natural resources.( )A. | is | B. | are | C. | is there | D. | are there |
分析 缺少自然资源是人类面临的众多危机之一.
解答 答案:A、
根据句子结构可知,该句为完全倒装句.用法为,表示方式或方位的副词或介词短语放句首(该句中为(among the crises that face humans),句子要使用完全倒装,即把谓语动词提前到主语之前.由此可知,该句的主语为the lack of natural resources单数,句子本来应为The lack of natural resources is among the crises that face humans.因此选择B项.
点评 倒装英语句子的主语通常位于谓语动词之前,这种语序被称为正常语序.但有时出于修辞或某种特殊的语法结构的需要,需要将谓语动词放在主语之前,这种语序则叫倒装语序.主语和谓语完全倒置叫完全倒装.所以在选择谓语动词的单复数时要找准主语.
