题目内容
20.We are living in an age QR codes(二维码)are becoming more and more popular in our daily life.( )A. | why | B. | that | C. | whose | D. | when |
分析 我们生活在一个二维码在日常生活中越来越受欢迎的时代.
解答 答案为D.本题考查从句中引导词的选择.题干中第一空格后面是修饰和限制名词the age的定语从句,把先行词the age带入到定语从句,完整的定语从句是"in the age QR codes(二维码)are becoming more and more popular in our daily life";可见in the age 在从句中充当时间状语.定语从句中关系副词when可指代时间在从句中做时间状语,故选D.
点评 选择定语从句中的关系词,首先要理解各关系词的用法;然后找准先行词,将先行词带入到定语从句;最后根据先行词在定语从句中的作用判断关系词.
