答案解析
16.【解析】选C。考查名词性从句的语序。根据特殊疑问词引导宾语从句时用陈述语序可知，A、D两项错误；deal with与how而不与what搭配，故B项错误。
17.【解析】选B。考查名词性从句。句意：直到那时亨利才意识到他犯了一个多么严重的错误。宾语从句由感叹句来充当，结构应为“what +a(n)+形容词+可数名词单数+主语+谓语！”或“How+形容词+a(n)+可数名词单数+主语+谓语！”，故选B。
18.【解析】选D。句意：一些青少年没有意识到的是吸毒成瘾之后生活是多么艰难。_______ some teenagers don’t realize为主语从句，且从句中缺少宾语，故用what。that在名词性从句中不作成分，故排除A、B两项；表语从句为how引导的感叹句，故D项正确。
【易错提醒】本题易误选C项，以为该感叹句的中心词为名词life，difficult用来修饰life，但实际上difficult在该感叹句中作be的表语，故用how。
19.【解析】选B。考查名词性从句和强调句型。句意：我真的不明白是什么使我儿子今天上午这么难过。该强调句型强调的是what，并且what在宾语从句中作主语，名词性从句应使用陈述语序，故B项正确。
20.【解析】选B。考查名词性从句。句意：你能告诉我新产的iPad对我们的日常生活有什么作用吗？_______ use the newly-produced iPad can be of to our daily life为宾语从句，且该从句中缺少定语，其正常语序应为. . . can be of _______ use to. . . 根据句意可知用what。how为连接副词，在句中作方式状语；if是否，在引导名词性从句时不作任何成分；whose尽管可以用作定语，但意为“谁的”，不符合语境。
21.【解析】选D。考查名词性从句。句意：弗朗索瓦·奥朗德当选为法国总统的消息迅速传遍全世界。_______ Francois Hollande had been elected President of France为同位语从句，说明news的内容，该从句中不缺少任何成分，故用that引导。what和which为连接代词，在名词性从句中充当句子成分; whether引导名词性从句时不作成分，但有词义，意为“是否”。
22.【解析】选C。考查名词性从句。句意：面对麦克哈尔的挑战，李娜认为信心会产生很大的作用。_______ would make a difference为表语从句，该从句中缺少主语，故用what。that和whether均为连接词，引导名词性从句时不作任何句子成分；which表示在一定范围内进行选择。
23.【解析】选B。考查名词性从句。句意：众所周知，2016年奥运会将在巴西里约热内卢举行。_______ is well-known to all为主语从句，且该主语从句中缺少主语，故用what。
【易错提醒】本题易误选A、C两项。如果理解为as引导的非限制性定语从句，则题干需改为_______ is well-known to all, the 2016 Olympic Games will be held in Rio de Janeiro, Brazil. 。如果用it作形式主语，则题干应为_______ is well-known to all that the 2016 Olympic Games will be held in Rio de Janeiro, Brazil. 。
24.【解析】选C。考查名词性从句。句意：——这个周末我们改变一下，去看电影《复仇者联盟》怎么样？——好的，你想做什么（就做什么）。whatever无论什么；whichever无论哪一个；however无论怎么样；whoever无论谁。
25.【解析】选B。考查名词性从句。句意：尽管国际社会在努力，但是叙利亚何时会恢复正常我们还不知道。根据句意可知应该使用when引导主语从句，且when在从句中作时间状语。where表示地点；how表示方式；why表示原因。

Ⅰ.单项填空
1．__________ made the little boy so sad is __________ his parents didn’t allow him to go out for a picnic with other boys.
A．What；because B．What；that
C．That；because D．That；what
解析：选B。句意：使这个小男孩如此伤心的是他的父母不允许他跟其他男孩出去野餐。第一空用what引导主语从句，what在从句中作主语；第二空用that引导表语从句，that在从句中不作任何成分，也没有实际意义，只起连接作用。
2．—What did you do yesterday afternoon?
—We discussed __________ Mary could join us.
A．whether B．if
C．that D．what
解析：选A。句意：“你们昨天下午干什么了？”“我们讨论了玛丽是否可以加入到我们中来。”discuss后的宾语从句只用whether不用if引导，意为“是否”，且不在从句中作成分。that在名词性从句中不作任何成分也没有任何意义；what常在名词性从句中作主语、宾语、表语等。
3．The textbook is filled with cases about __________ our life has developed thanks to new inventions.
A．what B．where
C．why D．how
解析：选D。句意：课本中有很多关于我们的生活是如何因为新发明而得到改善的例子。根据句意宾语从句缺少表示方式的状语，故用how引导。what不作状语；where表示地点；why表示原因。
4．Desertification，the name for __________ happens when farm land is turned into desert，is a growing world problem.
A．which B．where
C．what D．how
解析：选C。句意：沙漠化，即可耕种土地变成沙漠，已经发展成世界问题了。所选项引导介词for的宾语从句，并在从句中作主语，故用what。which强调范围；where常在名词性从句中作地点状语；how在名词性从句中作方式状语。
5．__________ we’ll go camping tomorrow depends on the weather.
A．If B．Whether
C．That D．When
解析：选B。句意：明天我们是否去野营取决于天气。所选项表示“是否”之意，且从句中不缺少成分，故用whether。引导主语从句位于句首时，用whether不用if；that在名词性从句中不作任何成分也无任何意义；when常在名词性从句中作时间状语，此处与tomorrow相矛盾。
6．(2012·临沂质量检测)The warning we were given as children __________ eating fast will make you fat may，in fact，have a scientific explanation.
A．that B．who
C．where D．which
解析：选A。考查名词性从句。分析句子可知，we were given as children为定语从句限定主语the warning，其谓语动词为have，从句部分不缺成分，对the warning起到补充说明的作用，为同位语从句。故选A。
7．(2012·泰安一轮质量检测)—It is so dark tonight，Mum.
—Yes，this is just __________ we can enjoy brilliant stars in the sky.
A．when B．where
C．how D．because
解析：选A。考查名词性从句。句意：——妈妈，夜深了。——是的，这时候我们正好可以观看天上闪闪的星星。句中is后接的是表语从句，从句中缺少原因状语，应用when引导。故选A项。
8．(2012·淄博模拟)—Are you still thinking about the e-mail Tony sent you yesterday?
—Oh，to tell the truth，that’s __________ makes me feel excited.
A．what B．how
C．that D．why
解析：选A。考查名词性从句。由语境知，正是Tony的邮件使“我”非常兴奋。what相当于the e-mail that，即作is的表语，又作makes me feel excited的主语。故选A。
9．(2011·潍坊5月份训练)The shoes in our store are all of good quality.You can choose __________ you like.
A．whichever B．however
C．whatever D．wherever
解析：选A。考查连接词。宾语从句中缺少宾语，所以排除B、D两项；选择的鞋子应是前文中所指的，所以用连接代词whichever。故选A项。
10．(2012·青岛统一质量检测)__________ is expected that it will be fine tomorrow，when we can do some outdoor activities.
A．As B．It
C．That D．Which
解析：选B。考查名词性从句。由语境知，大家都指望着明天天气晴好，这样就能做些户外活动了。分析题干知，此处考查主语从句固定结构，即It is＋过去分词＋that-clause。其中it作形式主语，故B项正确。
