2、eat Chinese poet, was born is known to the public, but some wont accept it.AThatBWhyCWhereDHowC考查名词性从句引导词的选择。句意：中国的大诗人李白的出生地众所周知，但有些人还不认可。分析句子结构可知，a great Chinese poet是Li Bai的同位语，where Li Bai.was born是主语从句，表示“李白出生的地方”。3(2014江苏高考，26)What a mess！You are always so lazy!Im not to blame，mum.I am _ you ha
3、ve made me.AhowBwhatCthatDwhoB考查名词性从句引导词的选择。句意：“真是一团糟！你总是这么懒惰！”“妈妈，我不应该受到责备。我这个样子都是你一手造就的。”分析句子结构可知，I am后是表语从句，引导词what在从句中作me的补足语，相当于the one/person that，即I am the one/person that you have made me.。类似的例子还有：He is no longer what (the one/person that)he used to be.。what在此类句子中意为“的，具有特征的”，相当于the one that/
4、the person that/the things that/all that。4(2016北京高考，24)Your support is important to our work._ you can do helps.AHoweverBWhoeverCWhateverDWhereverC考查主语从句。句意：你的支持对我们的工作很重要。无论你能做什么(whatever)，都会对我们有帮助。分析句子结构可知，所填词引导主语从句，且在从句中作do的宾语，所以C项whatever“无论什么”符合语境。however“无论多么”和wherever“无论在哪里”是关系副词，在句中作状语，可排除A、D
5、两项；whoever“无论是谁，不管是谁”，不能作do的宾语，B项也可排除。5(2016北京高考，29)The most pleasant thing of the rainy season is _ one can be entirely free from dust.AwhatBthatCwhetherDwhyB考查表语从句。句意：雨季最愉快的事情莫过于不受灰尘的袭扰。分析句子结构可知，此处是表语从句，且从句中不缺任何成分，故用that引导，所以选B项。6(2016天津高考，11)The manager put forward a suggestion _ we should have a

7、船的本意。从ships are built for来看，表语从句的引导词作for的宾语。why和when是连接副词，不能作宾语，而whom指人，因此选what。8(2015浙江高考，6)If you swim in a river or lake，be sure to investigate_is below the water surface.Often there are rocks or branches hidden in the water.AwhatBwhoCthatDwhoeverA考查宾语从句引导词的选择。句意：如果你在河里或者湖里游泳，一定要弄清楚水面下有什么。经常有岩石或者
8、树枝藏在水里。分析句子结构可知，此处investigate后接了宾语从句，从句缺少主语，故用what引导。who与whoever都可以作主语，但是不符合句意；that在名词性从句中仅仅起连接作用，不作句子成分。名词性从句包括主语从句、宾语从句、表语从句和同位语从句四种。每一种从句都有自己的引导词，引导词都位于从句句首，且从句使用陈述语序。一、名词性从句的引导词引导词用法连词that，whether，if等均不在句子中作成分。that没有意义，引导宾语从句时可以省略；whether和if意为“是否”，在宾语从句中可互换使用，但在其他名词性从句中只用whether连接代词what，who，whom
