题目内容
14.China's New Food Act provides for a food recall system_____producers have to stop production _____their food isn't up to standards.( )A. | that; if | B. | where; if | C. | which; when | D. | when; where |
分析 中国新食品法规定了食品召回制度--如果食物达不到标准,生产商必须停止生产.
解答 答案:B
该题考查定语从句和状语从句,结合句意并分析句子结构,system为先行词,___producers have to stop production ___their food isn't up to standards为修饰system的定语从句,由于定语从句不缺乏名词性成分,所以先行词system可当做地点看待,故应该使用引导词where或in which引导定语从句,分析该定语从句,___their food isn't up to standards在该定语从句当中作条件状语从句,结合句意,应使用if引导该条件状语从句,故选B.
点评 考查定语从句,必须先对句子基本结构进行分析,否则先行词,从句,及关系词选用会出现错误.
