试题分析:考查主语从句:句意:要不要修建一所现代旅店来取代这座旧巴士站仍在讨论中!从句意看是用whether,前面it是形式主语,真正的主语是whether引导的从句。可以用it替代后面的从句做形式主语。选A。
点评: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。连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述。连接副词主要有when, where, why, how, whenever, wherever, however等.
