__________knowledge comes from practice is known to all.
A.IfB.WhatC.WhereD.That
D

试题分析:考查主语从句:分析句子可知is是谓语,前面的句子是主语从句,因为主语从句是完整的句子,用that连接主语从句,而且不可以省略,句意:知识来自于实践是众所周知的。选D。
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。
