(2014年北京市西城区高三5月二模试题)23. It’s been discovered in the study ______ people are more relieved after forgiving others.
A.thatB.whatC.whichD.whose

答案
A
解析
本句中的it是形式主语,that引导的是真正的主语从句,that在这个主语从句中u充当任何成分,只是一个引导词而已。句意:在研究中人们已经发现在原谅别人以后人们更加宽慰。BCD三项都要在句中做成分的。故A正确。
【试题延伸】主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。解答这类题目,关键在于分析清楚句子结构。通过判断引导词在从句中所作的成分及意义,来选择正确的引导词。连接主语从句的从属连词主要有that, if, whether,和疑问词(what how where when ...)。that引导表示陈述句的主语从句,if和whether,whether...or not引导表示“是否”,引导一般疑问句。连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。
