题目内容
16.Don't talk about such things _______ you are not sure about.( )A. | which | B. | that | C. | as | D. | what |
分析 不要谈论你没有把握的事情.
解答 答案:C
句中you are not sure about修饰名词things,是一个定语从句;先行词被such修饰,关系词要用as来引导,构成such…as…结构.故选C.
点评 定语从句是用来修饰名词的形容词性从句,相当于一个形容词.连接定语从句的引导词分为关系代词和关系副词,关系代词在从句中要作主语或宾语;关系副词在从句中作状语.这也是选择关系词的一个判断方法.
