在高二上册我们学过了有关名词性从句的用法。名词性从句几乎每年高考都要考,在各种题目中也经常出现,它也是复合句中比较难以掌握的语法内容之一,因此应切实掌握这一考点。其中名词性从句的连接词的考查是重中之重,考生如何正确理解句子的含义,选取正确的连接词,是把握好这一类题目的关键。

　　名词性从句包括表语从句、宾语从句、主语从句和同位语从句.其关联词有that, if , whether, who, what, which, when, where, why等。

　　笔者把最近几年的有关名词性从句的高考试题进行了分类整理,并加以分析,同时又加注了各种名词性从句的基本特点,希望能为同学们掌握好名词性从句的用法提供一些帮助。

　　一、对表语从句的考查

　　表语从句在句子中作表语,位于主句中的系动词之后。

　　[考例1] - Are you still thinking about yesterday's game?

　　-Oh, that's_______ . (2003北京春季)

　　A. what makes me feel excited_______

　　B. whatever I feel excited about

　　C. how I feel about it

　　D. when I feel excited

　　解析:上文的关键词语"still thinking about yesterday's game"决定必然用表语从句what makes me feel excited ,表示比赛留下久久不能忘怀的印象,豪情激发,现在还在thinking;B项是泛泛而指,当然不行;C和D项内容与上下文问题无关。故答案为A.

　　[考例2]-I drove to Zhuhai for the air show last week.

　　-Is that_______ you had a few days off?(NMET1999)

　　A.why B.when C.what D.where

　　解析:这是一个由why引导的表语从句,表示原因.这句话的意思是"这就是你离开的原因吗?"。故答案为A。

　　[考例3]Perseverance is a kind of quality and that's_______ it takes to do anything well.( 2002上海春季)

　　A. what B. that C. which D. why

　　解析:what在表语从句中作takes的宾语,构成"It takes sth. to do sth."的句型。答案为A。

　　二、对宾语从句的考查

　　宾语从句在句子中作及物动词或介词的宾语.如果主句的谓语动词是及物动词make, find, see, hear等,则把宾语从句置于宾语补足语之后,用it作形式宾语.另外,某些作表语的形容词,如sure, happy, glad, certain等之后也可以带宾语从句。

　　[考例4]Mr. Hall understands that_______maths has always been easy for him, it is not easy for the students. ( 2003安徽春季)

　　A. unless B. since C. although D. when

　　解析:该题考查连词在宾语从句中的用法.观察题干Mr. Hall understands是主句,其后有that引导的宾语从句,可将该句简化为: _______maths has always been easy for him,it is not easy for the students.分析简化后的句子可知,maths has always been easy for him与it is not easy for the students之间含有转折关系,其他选项不合题干逻辑。故答案为C。

　　[考例5]When you answer questions in a job interview, please remember the golden rule: Always give the monkey exactly_______ he wants .(2002上海春季)

　　A.what B.which C.when D.that

　　解析:这是一个宾语从句,wants后面缺少宾语,Always give the monkey exactly what he wants是一句谚语,意思是"永远给予他人他确实想要的东西"。故答案为A。

　　三、对主语从句的考查

　　主语从句在从句中作主语,它可以放在主句谓语动词之前,但多数情况下由it作形式主语,而把主语从句放在主句之后。

　　[考例6]_______fashion differs from country to country may reflect the cultural differences from one aspect.(2002上海春季)

　　A.What B.That C.This D.Which

　　解析:这是含有一个主语从句的句子。因为主语从句是一个完整的句子,所以要填写that。这句话的意思是"国与国之间的时装差异可以从一个方面反映出其文化的差异"。答案为B。

　　[考例7]_______ she couldn't understand was_______ fewer and fewer students showed interest in her lessons.( 2000上海)

　　A.What;why B.That; what C.What; because D.Why; that

　　解析:答案为A。主语从句she couldn't understand缺少宾语,要用what引导。表语从句fewer and fewer students showed interest in her lessons是一个完整的句子,要用why引导,意思是"为什么越来越少的学生对她的课感兴趣。"

　　四、对同位语从句的考查

　　同位语从句一般跟在某些抽象名词概念的名词后面,用以说明名词所表示的具体内容,常跟同位语从句的名词主要有:idea, news, promise, answer, belief, condition, doubt, fear, hope, problem, proof, question, reply, report, suggestion, thought, truth等。

　　[考例8]Information has been put forward_______ more middle school graduates will be admitted into universities.( 2001上海)

　　A.while B.that C.when D.as

　　解析:that引导从句作information的同位语,解释information的具体内容.这句话的意思是"有消息说,有更多的中学毕业生将进入大学"。由于information与同位语从句被has been put forward分隔开来,增加了试题的难度。

　　2. A.what引导主语从句,作said的宾语。

　　3.C.whether引导主语从句,if不能引导位于句首的主语从句,A、D不合题意。

　　4.B.whether引导表语从句,而不用if。

　　5.B.同位语从句说明fact的具体内容,只用that引导,不能省略.不用which引导,that只起连接作用,不作句子成分。

　　6.C.that引导同位语从句,说明promise的具体内容。

　　7.B.when引导宾语从句,表示"那时,这是个僻静的村庄"。village已有quiet修饰,不能再用how引导从句,C、D不合题意。

　　8.C.首先排除D ,who引导主语从句并作从句的主语,whom不能作主语,whoever则表示"无论谁",与句意不符。

　　9. B.whatever引导宾语从句,在从句中作wants的宾语。用whichever引导,则表示"任何一个",与题意不符,A、D都只能作状语。

　　10. A.what引导主语、宾语从句,可作从句中的主语或宾语,而that引导名词性从句时在句子中不作成分。
