题目内容

_____________ we all know is that destroying nature means destroying ourselves.

A．what

B．Which

C．That

D．It

解析试题分析：考查主语从句。本题中的what we all know是一个主语从句，what引导起该从句，并在句中作为动词know的宾语。句意：我们都知道的事情是破坏大自然就意味着毁灭我们自己。It不能引导主语从句，that在主语从句不充当任何成分，which是指特定范围之内的某一个。故A正确。
考点：考查主语从句
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.

In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
