1主语从句与表语从句知识点1. 名词性从句引导词的选择选择原则“缺什么，补什么，什么不缺，用 that”“什么不缺，用 that”的意思是：如果从句中不缺任何成分，而且句意完整时，就用 that 来引导主语从句或表语从句以及其他的名词性从句。2. whether 意为 “是否” ，引导的主语从句放在句首，不能用 if 代替； 但当用it 作形式主语时，whether 引导的主语从句放在句中或句末，此时可换用 if. It is doubtful whether therell be any seats left.说不上是否还有座位了。3. that 引导主语从句时，只起连接作用，不作任何成分，没有实际意义。在句首时不可省略。What 引导主语从句时既要起连接作用，又要在从句中作主语或宾语，在任何情况下都不能省略，它具有具体意义，表示“什么，所的（事、物、话） ”，相当于 all that/ everything that. Which 引导主语从句也作成分，它表示选择的意义，常译为“那个” 。如： That he survived in the earthquake is a miracle. 他在地震中幸免于难，这是个奇迹。4. 关系代词 what, which, who 引导主语、表语从句时含有疑问意义，而whatever, whichever, whoever 在引导名词性从句时，往往比 what, which, who更强调， 不表示疑问意义。而且 whatever=all that/everything that; whichever=anything that; whoever=anyone who.另外， whatever=no matter what时引导状语从句。如：Whatever is worth doing at all is worth doing well.凡是值得做的事情都值得好好地做。 I 语法填空。使用正确连接词补全下列句子。1.
