题目内容
18.An electric salt-flavored fork has been developed as part of the No Salt Restaurant project,___aims to offer low-salt or salt-free food.( )A. | that | B. | where | C. | which | D. | in which |
分析 作为无盐餐馆项目一部分的一种电子调味餐叉已经被开发出来,其目的是提供一种低盐或无盐的食物.
解答 答案:C
句中aims to offer low-salt or salt-free food修饰前面的project,是一个非限制性定语从句;从句缺少主语,且先行词project指物,要用which来引导.故选C.that不能引导非限制性定语从句.
点评 定语从句是一类比较重要的复合句.定语从句关系词的选择要根据从句的结构来确定,从句如果缺少主语或宾语,要用关系代词;从句结构如果完整,要用关系副词.学习时,要注意区分和掌握.
