题目内容
13.Nowadays,it is common to see people staring at their mobile phones instead of reading a real book,____ many experts are worried.( )A. | when | B. | for which | C. | about which | D. | where |
分析 现在,看见人们盯着手机看而非读真正的书是很常见的,对此专家很担心.
解答 答案是C.本题考查"介词+关系代词";题干中逗号后面是非限制性定语从句,从句中关系代词指代整个主句;从句完整的表达是"Many experts are worried about _____";可见从句中缺少的是介词about和 about的宾语which,其中which 指代主句,故答案是C;
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.
