man

form
the
foundation
of
modem
physics
today”在句中作定语，是定语从句，修饰先行词ideas，先行词ideas在定语从句中作主语，指物，而且由the
most修饰，需用关系代词that引导。故选D。
3.【答案】B
【解析】考查让步状语从句和主语从句。句意：——无论我什么时间看电视，我都会把声音调低一点，从不发出任何噪音。——很好，无论你做什么，都不要打扰别人。不管你有多重要，永远不要忘记别人的感受。首先看第一个空，根据句意和句子结构可知，本句为让步状语从句，表示无论何时，故应用Whenever引导让步状语从句，相当于No
matter
when。再看第二空，根据句意和句子结构可知，句子为主语从句，“
you
are
doing”在句中作主语，从句中缺少are
doing的宾语，表示无论做什么事，故用Whatever来引导主语从句，意为任何事情，相当于anything
what。再看第三个空，根据句意和句子结构可知，本句为让步状语从句，表示不管多么重要，故应用No
matter
how引导让步状语从句，相当于however。故选B项。
4.【答案】C
【解析】考查名词性从句和固定短语。句意：你能否成功取决于你有多努力。句中出现or
not，分析句子可知，此处是whether引导的主语从句，引导主语从句位于句首时不能用If。depend

is
no
use
doing
sth.意为：做某事是没有用的，该句型是固定句型；“

6.【答案】B
【解析】考查定语从句。句意：许多化学防晒霜中的活性成分是否安全，对此科学家们没有达成共识。分析句子结构可知，设空处引导从句作同位语，表示的是解释说明agreement的内容；从句表达完整的意思，不缺少成分。故答案为B。

is
no
doubt
that，表示毫无疑问。本句为that引导的同位语从句，句意和句子结构完整。故选C项。
8.【答案】B
【解析】考查名词性从句和定语从句。句意：人们认为工厂应该少用原材料生产东西，且对此的供给也会愈来愈少。第一空表示的是belief一词的同位语从句，故使用that；第二空为非限制性定语从句，其先行词为前面一句中的few
things，故使用of
which适合；如果要使用whose引导的话应该去掉supply前面的定冠词the才可以，故选B项适合。
9.【答案】B
【解析】考查非限制性定语从句和同位语从句。句意：众所周知，威廉违背了给我们加薪的诺言。分析句子结构可知，第一个空是关系代词as引导的非限制性定语从句，先行词是逗号后面的句子，且先行词在从句中做主语，如果用It做形式主语，all后就不能加逗号；promise之后引导的是同位语从句，解释说明promise的内容，用that来引导同位语从句。综上所述，故选B。10.【答案】D
【解析】考查同位语从句、-ing形容词和-ed形容词的区别。句意：我可能会迷路的想法让我感到担心。-ing形容词经常修饰事物，意思是“令人怎么样的”，-ed形容词经常修饰人或者人的表情及反应等，意思是“人感到……”。此处表示“我感到担忧”，因此使用worried。从句是在解释名词thought的内容，且在语意和成分上均完整，因此使用that引导同位语从句。故选D。
11.【答案】C
【解析】考查定语从句和表语从句。句意：他发生事故的原因是他开车太粗心。分析句子结构，第一空引导定语从句，修饰名词the
reason，从句不缺成分，需用关系副词引导，先行词在定语从句中作原因状语，需用why引导，why=for
which，第一空填which；第二空位于系动词was后面，引导表语从句，从句不缺成分，且句意完整，需用连接词that引导。故选C。
12.【答案】D
【解析】考查定语从句和表语从句。句意：电视台被迫想出更好的节目的原因是，如今越来越多年轻的父母更喜欢花时间给孩子读故事，而不是扎根在电视机前。第一空引导定语从句，先行词是reason，关系词在从句中作原因状语，所以使用why引导；第二空引导表语从句，从句结构、意义完整，应使用that引导，故选D项。
13.【答案】C
【解析】考查表语从句。句意：地球上的每个人都不一样，那造就了地球的美丽。分析句子可知，系动词is后是表语从句，从句缺少主语，what引导表语从句，从句中作主语，when“当……时”作时间状语；how“如何”作方式状语；why“为什么，……的原因”作原因状语。故选C。
14.【答案】D
【解析】考查关系词和连接词。句意：女孩在求学生涯的所有阶段都要胜出男孩一筹的理由是女孩比男孩成熟的要快得多，而且更自律更认真。the
reason
why...is
that...是固定句型，why引导的是定语从句，从句中作原因状语。that引导表语从句。故选D。
15.【答案】D
【解析】考查宾语从句引导词。句意：人们涌向樱花盛开的地方，欣赏清新的春光。从句做介词into的宾语，且从句缺少地点状语。where
=
in
which，结合句意，“樱花盛开的地方”。故选D。
16.【答案】C
【解析】考查表语从句。句意：空气污染是现在大多数中国人关心的问题，因为他们的健康正受到威胁。此处be动词后面是表语从句，从句缺少引导词，谓语动词短语“are
concerned
about”缺少宾语，所以所填词要起双重作用，应填what，故选C。
17.【答案】B
【解析】考查主语从句。句意：很明显，学生们应该为他们的未来做好准备。“It”是形式主语，真正的主语是后面的主语从句，引导词在从句中不作任何成分，也没有实际意义，用that，故选B。
18.【答案】C
【解析】考查表语从句。句意：昨天是历史，明天是未知，只有今天是一份礼物，这就是为什么我们称“今天”是“礼物”。“______
we
call
it
present.”是一个表语从句，引导词在从句中作原因状语，用“why”引导，故选C。
19.【答案】B

the
Long
March.”是一个表语从句，引导词在从句中作宾语，表示“学习的事情”，用what，故选B。
20.【答案】A
【解析】考查表语从句连接词。句意：谦虚是一种良好的品质，它能让你成为最好的自己。分析句子可知，“which
is”后面的句子为表语从句，在表语从句中，“take”缺少宾语，所以用“what”来充当其宾语。故A选项正确。
21.【答案】B

Whatever无论什么；B.
Whichever无论哪一个；C.
Whenever无论什么时候；D.
Wherever无论哪里。前句已经给出两个时间点，即“seven
o’clock
or
the
eight”意为“七点还是八点”，需要你确定一个，因此“whichever”意为无论哪一个，符合题意。故B选项正确。
22.【答案】A
【解析】考查主语从句。句意：我终于相信别人对你的看法是什么不重要，最重要的是你对自己的态度。该句结构复杂，“that
it’s
of
no
importance
______
others

23.【答案】B
【解析】考查名词性从句连接词。句意：同样的沸水使土豆变软，使鸡蛋变硬。重要的是你是由什么构成的，而不是环境。本句位于介词“about”后，是宾语从句，从句中缺少宾语，指代事物，用“what”，故选B。
24.【答案】C
【解析】考查宾语从句。句意：你应该设定一个目标并看你是否能在即将来临的考试中实现目标。根据句意可知，此处表示“是否”，故C项正确。
25.【答案】A
【解析】考查同位语从句。句意：鲍勃向经理保证将按时完成工作。分析句子结构可知，此处为同位语从句，从句意思、成分完整，从句解释“promise”的内容，只起连接作用，无实义，故用连接词“that”，A项正确。
二、单句语法填空
1.【答案】that
【解析】考查主语从句。句意：我从没想到过你能说服他改变主意。It是形式主语，真正的主语是
you
could
succeed
in
persuading
him
to
change
his
mind这一从句，且从句不缺成分，句意完整，所以用that引导。故填that。
2.【答案】Whether
【解析】考查名词性从句连接词。句意：她来不来都没有关系。此处为主语从句，从句中不缺少成分，与后文or
not构成短语whether...or
not，表示是否，故应用whether。句首单词首字母要大写。故填Whether。

off
the
lights（关灯）的动作的人，侧重表达“无论是谁”离开房间，都要关灯，故应用whoever引导。故填Whoever。
4.【答案】whether
【解析】考查同位语从句。句意：你还没有回答我的问题，我是否可以参加今晚的聚会。分析句子可知，空格后面的句子是my
question的同位语，从句中不缺少成分，只缺少是否的含义，故填whether。

【解析】考查表语从句。句意：你说人人应该平等，这正是我不同意你的地方。“
I
disagree”是一个表语从句，在从句中缺少地点状语，应用where引导。故填where。
9.【答案】where
【解析】考查名词性从句。句意为：不要因为觉得一份工作太小就拒绝它，你不知道它能引向何方。“know”后面接了宾语从句，“lead”是不及物动词，后面不缺成分，故用副词引导从句，根填where。
10.【答案】whether
【解析】考查主语从句。句意：——我确信我们会在你的生日聚会上与Henry玩得很开心。——也许吧，但是他能否抽出时间来还是个问题。分析句子结构可知，“it”是形式主语，后面的从句是真正的主语，关系词在句中不作成分，但是有词义，表示“是否”，故填whether。
11.【答案】that
【解析】考查同位语从句的连接词。句意：也有人反对童话故事，理由是它们在客观上不真实，巨人、女巫、双头龙等不存在。分析句子可知，本句空格是同位语从句的连接词，其中“they
are
not
objectively
true,
and
that
giants,
witches,
two-headed
dragons
etc.
do
not
exist.”是对名词“the
grounds”（理由）加以解释说明，二者是同位语的关系。分析句子可知，同位语从句中不缺少成分，只是缺少一个引导词，连接词“that”在名词从句中不作成分，只起引导的作用，故填that。
12.【答案】What
【解析】考查主语从句连词。句意：学习中重要的是勤奋而不是智力。本句中“what”指代“重要的事”引导主语从句，并在句中充当主语。故填What。
