高考题中的名词性从句考点一：宾语从句1.The companies are working together to create_______they hope will be the best means of transport in the 21st century.(2008 北京)A.whichB.thatC.whatD.who选A。
解题思路：首先判断该句是哪种类型的名词性从句。
横线前是动词create，其后应接宾语，那么此句是宾语从句；其次看从句中缺少什么句子成分。
They hope为插入语，没有实际意义，可删除。
那么从句缺少主语，故选C。
Which意为“哪一个”，that当从句中主谓宾齐全时，不充当任何成分，who做主语，指人。
2.A good friend of mine from______I was born showed up at my home right before I left for Beijing.(2009安徽)A.howB.whomC.whenD.which选C。
解题思路：首先判断该句是哪种类型的名词性从句。
横线前是介词from，介词后应接宾语，故为宾语从句；其次看从句中缺少什么句子成分。
后面的从句I was born缺少状语，I was born既可以接时间也可以接地点，这里应该接地点更合适，From when I was born=From the time when I was born，意为“自从我出生起”。
整句话就翻译为“就在我动身去北京前，我小时候结交的一位好朋友出现在我家里”。
3.When you answer questions in a job interview, please remember the golden rule: Always give the monkey exactly _______ he wants. (上海2002春)A. whatB. whichC. whenD. that选A。
本题考查宾语从句。
wants后面缺少宾语，只能选what。
Always give the monkey exactly what he wants是一句谚语, 意为“永远给予某人他确实想要的东西”。
4.Mary wrote an article on _______ the team had failed to win the game. (2005全国卷Ⅰ)A. whyB. whatC. whoD. that选A。
介词on后面跟由why引导的宾语从句，why在从句中作状语。
5. —I think it is going to be a big problem.—Yes, it could be.—I wonder ______ we can do about it. (北京2002春季)A. ifB. howC. whatD. that答案C。
本题考察名词性从句的连接词的用法。
wonder后面应跟宾语从句，而从句中的谓语动词do是及物动词，可见从句缺少一个代替宾语的成分，我们可以用排除法排除不作成分的if和that，再排除引导方式状语的how，答案是C，句子的意思是“我们能就此做些什么”。
6.His writing is so confusing that it’s difficult to make out _____it is he is trying to express.(2011安徽卷)A. thatB. howC. Wh oD. what答案：D。
考查名词性从句。
句意为：他的笔迹非常混乱，很难弄清他想表达什么意思。
本题考查动词短语make out引起的的宾语从句，该空在宾语从句中作express的宾语，表示事物，故选择D项。
that在宾语从句中不作句子成分；how作方式状语；who作主语，指人。
只有what可用作宾语并且指事物。
7.Before the sales start, I make a list of ___B___ my kids will need for the coming season.(10山东)A. whyB. whatC. howD. Which8.Cindy shut the door heavily and burst into tears. No one in the office knew __D___ she was so angry.（10湖南）A. whereB. whetherC. thatD. why9.—It’s no use having ideas only .—Don’t worry.

Wherever14.Some people believe ___A____ has happened before or is happening now will repeat itself in the future. (14北京)A. whateverB. whenever.C. whereverD. however15. If you notice that when someone is missing or hurt, tell your teacherimmediately.(2014四川)改错：去掉when。
根据句意，如果你注意到有人失踪或受伤……，可知此处是that引导的宾语从句表陈述，故when多余。
16.But before long they began to see which was happening.(2012 全国新课标)改错：将which改成what。
此处what做宾语从句的主语，意为“看所发生的一切”。
17....but it doesn’t matter that I would win or not.(2000 全国卷)改错：将that改成whether。
Matter后接宾语从句，本句意为“我是否成功没有关系”，因此用whether。
18....I felt that it helped me understand what the world works.(2001 春季)改错：将what改成how。
Work在这里是不及物动词，不能用连接代词what做宾语，只能用连接副词how做状语。
19.I don’t know that they don’t like to talk with me.(2004 全国卷)改错：将that改成why。
Know后面接的是宾语从句，that在句中无意义，只起连接作用，根据句意“我不知道他们为什么不喜欢和我说话”可知，应填why。
考点二：主语从句1._______ has helped to save the drowning girl is worth praising. (上海1999)A. WhoB. Those whoC. AnyoneD. Whoever选D。
whoever是泛指，意为“无论谁”，相当于anyone who；who是特指。
如：I can”t remember at the moment who has said the words.2.To improve the quality of our products ,we asks for suggestions A had used the products.（10重庆）A. whoeverB. whoC. whicheverD. which3.___B____ fashion differs from country to country may reflect the cultural differences from one aspect. (上海2002春)A. WhatB. ThatC. ThisD. Which选B。
主语从句成分完整, 只缺一个引导词，所以选that。
句意：国与国之间时装款式的差异可以从一个方面反映出它们的文化差别。
4._______ in the regulations that you should not tell other people the password of your email account. (上海2005)A. What is requiredB. What requiresC. It is requiredD. It requires选C。
本句是带有主语从句的主从复合句，it作形式主语，that引导的从句是真正的主语，it与require之间为被动关系。
5.I read about it in some book or other，does it matter ____ it was ?（2001春季招生）A．where B．what C．how D．which答案D。
这是一个主语从句。
主语从句中缺少表语。
从上句的意思分析，应是哪本书，所以要填which，这句话的意思是“我在某本书中读到过有关这方面的内容，是哪一本书重要吗？”。
6.I want to be liked and loved for C I am inside.（10北京）A.whoB. whereC. whatD. How7.The limits of a person’s intelligence,generally speaking, are fixed at birth, but___B___ he reaches these limits will depend on his environment.(12安徽)A. whereB. whetherC. thatD. why8.Exactly _C___ the potato was introduced into Europe is uncertain, but it was probably around 1565.
