第四讲 名词性从句
1．(2016·江苏高考，21)It is often the case ________ anything is possible for those who hang on to hope.
A．why B．what
C．as D．that
D [考查主语从句。句意：通常情况下，对于那些心存希望的人，一切皆有可能。分析句子结构可知，it作形式主语，that引导的从句作真正的主语，故选D项。It is often the case that...可视为固定句式，意为“通常情况下……”。] 2．(2015·江苏高考，25)________ Li Bai, a great Chinese poet, was born is known to the public, but some won't accept it.
A．That B．Why
C．Where D．How
C [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!
—I'm not to blame，mum.I am ________ you have made me.
A．how B．what
C．that D．who
B [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/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.
A．However B．Whoever
C．Whatever D．Wherever
C [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.
A．what B．that
C．whether D．why
B [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 an assistant.There is too much work to do.
A．whether B．that
C．which D．what
B [考查同位语从句。句意：经理提了个建议——我们应雇个助手。要做的工作太多了。分析句子结构可知，空格后的同位语从句用来解释说明
suggestion的具体内容，从句中不缺成分且意义完整，故选B项that。]
【导学号：57732006】7．(2015·安徽高考，25)A ship in harbor is safe，but that's not________ships are built for.
A．what B．whom
C．why D．when
A [考查表语从句的引导词。句意：船停在港口是安全的，但那不是造船的本意。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.
A．what B．who
C．that D．whoever
A [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。
