There is no doubt _____ short sight is a serious problem among the youth of our country.
A.which B.whetherC.whatD.that

答案
D
解析

试题分析:考查同位语从句:句意:毫无疑问在我们国家年轻人目光短浅是一个很严重的问题。doubt是同位词,that引导的是同位语从句,对doubt的内容进行说明。要注意的是如果是There is doubt就应该用whether连接同位语从句。选D。
点评:解答这类题目,关键在于分析清楚句子结构,知道引导词的使用习惯。通过判断引导词在从句中所作的成分,来选择正确的引导词。连接同位语从句的从属连词主要有that, if, whether,和疑问词(what how where when ...)。that引导表示陈述句的同位语从句,if和whether,whether...or not引导表示“是否”的一般疑问句的同位语从句。
