同位语从句的引导词主要包括连词that、whether,以及连接代词和连接副词。1. 连词that常用于引导同位语从句,如"The idea (that) you can do this work well without thinking is quite wrong." 这个句子中,that引导的从句解释了idea的内容,不可省略。值得注意的是,在某些特定名词(如demand、wish等)后面,如"There was a suggestion (that) Brown should be dropped from the team.",需要用虚拟语气。
2. 连词whether可以引导同位语从句,如"The question (whether) we should call in a specialist was answered by the family doctor." 这里,whether表明是否的疑问。而if不能引导同位语从句。
3. 连接代词what、who、whom、whose也可引导同位语从句,如"I have no idea (what size shoes) she wears." 这里,what作定语;"The question (who will take his place) is still not clear." 从句中who作主语。
4. 连接副词when、where、how、why则引导时间、地点或原因的同位语从句,如"We haven’t yet settled the question (where) we are going to spend our summer vacation." 先行词为idea、plan等名词时,它们才能引导同位语从句,而不能用于定语从句中。
总的来说,同位语从句的先行词通常是名词,如fact、news等,而定语从句的先行词范围更广。同位语从句的引导词在定语从句中可能充当成分,而在同位语从句中仅起连接作用。例如,引导词that在定语从句中可能作宾语,而在同位语从句中仅起连接作用,而when、where、why在定语从句中作状语,但同位语从句中则不能转换为"介词+关系代词"的形式。
