答案
B |
解析
试题分析:考查同位语从句:句意:一些研究人员相信艾滋病的疗法肯定会被发现的。Doubt是同位词,因为是否定句,所以用that连接的是同位语从句,对doubt的内容进行说明,that不做成分,只起到连接的作用,如果是肯定句,就是用whether连接同位语从句。选B。 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。 |
