Question

It never occurred to me _____ you could succeed in persuading him to change his mind.

A．which

B．that

C．what

D．if

Answer 1

B

试题分析：考察主语从句。本句指的It是形式主语，真正的主语是后面的that you could succeed in persuading him to change his mind. that在句中不充当任何成分，只起引导和连接的作用。另外本句中还含有固定句式 sth occur to sb某人突然想起某事。句意：我从未想起过你会成功说服他改变主意。故B正确。
点评：在复合句中做主语的从句叫做主语从句，它的位置与陈述句基本结构中的主语相同。引导主语从句的关联词有：连词：that, whether；连接代词：who, whom, whose, what, which；连接副词：when, where, why, how；复合词：whatever, whoever, whomever, when?蛳ever, wherever, whichever, however.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。
