2015届高考英语一轮基础语法专项训练：专题二 《名词性从句》（人教版）

　　名词性从句

　　1．If I were any younger，I would do________I am interested in.

　　A．no matter what　

　　B．whatever

　　C．no matter which

　　D．whichever

　　答案 B及物动词do后面需要接宾语从句，排除A和C两项。whichever要有选择的范围，不合语境。2．________the young man is in great need of a computer in his work is known to his boss.

　　A．What

　　B．That

　　C．How

　　D．When

　　答案 B考查主语从句的用法。句意：据他的老板了解，这个年轻人在工作中急需一台电脑。从属连词that引导主语从句时没有实际意义，不担当句子成分，只起连接词的作用，不能省略。该句还可改写为：It is known to his boss that the young man is in great need of a computer in his work.3．Stage fright is a common example of________educators call a“lack of confidence”among

　　students.

　　A．that

　　B．what

　　C．which

　　D．whose

　　答案 B句意：怯场是教育者称之为学生们缺乏自信的例证中的一个很普遍的例子。what引导定语从句，并在从句中作call的宾语。名词性从句中不缺成分时才能用that引导。4．These shoes look very good.I wonder________.

　　A．how much cost they are

　　B．how much do they cost

　　C．how much they cost

　　D．how much are they cost

　　答案 C考查宾语从句。句意：这鞋看起来很好。我想知道它们花了多少钱。cost为实义动词，排除选项A和D；宾语从句应该使用陈述语序，排除B项，故选C。5．I'm stuck on this problem；you may ask________knows better than I.

　　A．whoever

　　B．whomever

　　C．anyone

　　D．the one

　　答案 A句意：这个问题难住我了；你可以去问一个比我理解更好的人。从句中缺少主语，可排除B项。C、D两项不能引导从句，可排除。whoever在此引导宾语从句，相当于anyone who。6．One of the glorious moments in my school life was________I was awarded the Mayor's

　　Award.

　　A．why

　　B．how

　　C．that

　　D．when

　　答案 D考查表语从句。句意：在我的学生时代，令我感到荣耀的时刻之一就是我被授予“市长奖”的时刻。句子的主语是one of the glorious moments，所以表语应是“当……的时候”。其他选项在语句上不通顺，故选D。7．________seems to be a strong competition in China for senior high students to enter unive

　　rsities does exist in other countries as well.

　　A．It

　　B．Which

　　C．What

　　D．That

　　答案 C考查主语从句用法。在这个主语从句中，设空处作主语，故用what。句意：在中国，高中生考大学似乎存在很激烈的竞争，这一现象在其他国家同样存在。8．Your friends were all worried over________you were sick.

　　A．that

　　B．which

　　C．what

　　D．the fact that

　　答案 D考查同位语从句。句意：你的朋友们都非常担心你生病这件事。the fact作worried over的宾语，that you were sick是the fact是同位语从句。9．________some teenagers don't realize is________difficult life can be after they get addic

　　ted to drugs.

　　A．That；how

　　B．Which；what a

　　C．What；what

　　D．What；how

　　答案 D考查名词性从句。句意：一些青少年没有意识到的是吸毒成瘾后生活是多么艰难。主语从句里面缺少宾语，故排除A，which意为“哪一个(些)”，不符合语境，排除B项；在感叹句中，how修饰形容词或副词，而what修饰名词，排除选项C，故选D。10．My high school friend，________I haven't seen for 20 years，is no longer________he was.

　　A．who；that

　　B．which；that

　　C．whom；what

　　D．that；what

　　答案 C句意：我中学时的朋友，我已经20年没见他了，不再是过去的样子了。第一空：空格前有逗号，可知是非限制性定语从句，所以其引导词不能用that；先行词指人，故排除which。第二空：空格后的表语从句中缺表语且表事物，所以用what。11．In recent years，there has been a heated argument about________it is necessary for

　　children to learn English from an early age.

　　A．whether

　　B．if

　　C．what

　　D．that

　　答案 A考查宾语从句。空白处在介词about之后，表示“是否”之间，且在介词之后引导定语从句，只能用whether，介词后通常不用if引导宾语从句。12．The problem will appear________a different welfare sys

　　tem will be created.

　　A．unless

　　B．whether

　　C．until

　　答案 B句意：是否创建一种不同的福利制度的问题将会出现。whether引导同位语从句，解释说明the problem的内容。if也有“是否”之意，但不能引导同位语从句。13．What I want to tell you is________I've made a decision that I will give up the job.

　　A．this

　　B．that

　　D．these
