分析句子结构可知，整个句子的谓语动词为"may reflect"，"______ fashion differs from country to country"为主语部分，主语从句中不缺少主、宾、表等成分，也不缺少任何意思，因此应该用连接词"that"引导主语从句，"that"在句子中无意义，但不能省略，指起连接作用。
故选：B。
【点评】本题考查名词性从句．解答此类题目首先要读懂句意和分析句子结构，判断是哪一种从句，然后分析从句中的成分，如果从句中不缺主宾表等成分，则应根据句意来锁定连接词．

故选：A。
【点评】单项选择题考查内容广泛，涉及词汇、语法、习语、日常用语等。在有限的题量中注意知识的覆盖面，设计特定的语境综合考查学生在一定语境中运用语言知识的能力。
4．It is obvious to the whole world__________the US has played dirty tricks to bully foreign companies like Hua Wei and TikTok in order to either destroy them or take them over.（ ）
A．as B．which C．whether D．that
【分析】全世界都很清楚，美国用肮脏的伎俩欺负华为和抖音这样的外国公司，要么摧毁它们，要么接管它们。
【解答】答案：D.分析句意，句中的it为形式主语，真正的主语为后面的从句"_______the US has played dirty tricks to bully foreign companies like Hua Wei and TikTok in order to either destroy them or take them over"。分析成分，从句部分不缺成分和翻译且为陈述句。所以从句应用引导词that引导。
故选：D。

故选：A。
【点评】必须明确that引导主语从句位于句首时不能省略。

【分析】他最喜欢的食物是油炸零食和软饮料，减肥只是他的梦想也就不足为奇了．

【点评】that和what引导名词性从句区别：that不做成分，what作主语、宾语、表语、定语．

【点评】名词性从句一直是高考考查的热点，近几年的高考题主要考查在具体语境中对what和that的辨析，此外，也要求学生对定语从句和名词性从句有清晰的辨认． 首先我们要判断它是哪个名词性从句．名词性从句是主句的一部分，可以充当主语、宾语、表语、同位语．就是说，如果我们能判断出某个从句是某个主句的主语、宾语、表语或同位语，

12．____the meeting should last two days or three days doesn't matter．（ ）
A．That B．Whether C．If D．Where
【分析】会议是否持续两天还是三天没关系．

13．______ Suqian won the title of National Civilized City made people in the city very excited．（ ）
A．That B．What C．Which D．Whether
【分析】宿迁赢得全国文明城市的称号使人们非常兴奋．
【解答】答案 A．
分析句子的结构可知，整个句子的谓语动词为"made"，之前的成分为主语，主语从句中句子结构已完整，意思也完整，因此用连词"that"引导主语从句，"that"在句中不充当成分，也无意义，只起连接词的作用，因此A项符合语境，
故选：A。
【点评】用从属连词that引导的主语从句，例如：
That we shall be late is certain．
That the driver could not control his car was obvious．
但是在一般情况下，往往使用先行it结构，即用it作形式主语，而把that从句放到后面，这时，在口语中，连词that有时则可以省略．所以上述两句可以改为：It is certain that we shall be late．
It was obvious that the driver could not control his car．
常使用先行it结构，用that从句作主语的句子有下列几个句型：
1、It + be + 形容词 + that从句：
It is clear that he was telling the truth．
It's probable that we'll be a little late．
2、It + be + 名词词组 + that从句：
It's a pity that you can't go with us．
3、It + 及物动词 + 宾语 + that从句：
It worried her a bit that her hair was turning grey．
It shocked me that Peter didn't tell anybody where he was．
4、It + be + 过去分词 + that从句：
It is said that he has been there many times．
5、It + seem/happen/appear等不及物动词 + that从句：
It seems that he has lost something．
第二类，用连接代词who、whose、which、what，连接副词when、where、how、why，以及连词whether（或if）引导的主语从句，例如：
Who was responsible for the accident is not yet clear．
→ It is not yet clear who was responsible for the accident．
What he did is not yet known．
→ It is not yet known what he did．
Whether it is true remains a problem．
→ It remains a problem whether / if it is true．
第三类，用what、whatever、where、wherever、whoever、whichever等代词引导的主语从句，例如：
What he said at the meeting encouraged everyone．
Whoever fails to see this will make a big blunder．
这类从句一般相当于带有定语从句所修饰的名词词组，即在结构上相当于一个名词加上一个定语从句，例如：
What he wants to buy is a ten﹣speed bicycle．
→ The thing that he wants to buy is a ten﹣speed bicycle．
Whoever breaks the law is sure to be punished．
→ Anyone who breaks the law is sure to be punished．
14．It is well known _____Confucius was born in the city of Qufu in Shandong province，China．（ ）
A．whether B．where C．that D．what
【分析】众所周知．孔子出生在中国山东的曲阜．
【解答】本题考查主语从句中的引导词；题干中考查句型"It is well known that…众所周知"，其中it 为形式主语，that引导了主语从句；本题中主语从句"Confucius was born in the city of Qufu in Shandong province，China"从意思到成分都是完整的，所以选择 在名词性从句中不担任成分、无意义that，除了在宾语从句中之外，that不可以省略；故选：C。
【点评】名词性从句考查的关键是连接词的选用和语序，因此，我们首先要搞清从句的性质，掌握各连接词的用法，在此基础上判断．此外，关注名词性从句用陈述语序．
15．________ the weather will not clear up until next week is bad news for us．（ ）
A．As B．If C．Whether D．That
【分析】考查主语从句，句意：天气到下周才会晴，这对我们来说是个坏消息．
【解答】答案：D，the weather will not clear up until next week 天气到下周才会晴，这是事实，所以排除B和C选项，此句作主语，排除A选项，as不引导主语从句，此句是完整句子，不缺少句子成分，所以用that．引导主语从句，that在从句中不作成分，无含义．
【点评】弄清句子结构，理清连接词的含义及功能．
16．It is obvious _________bike﹣sharing has a future in China．（ ）
A．what B．that C．where D．if
【分析】很显然共享单车在中国有前景．
【解答】答案是B．本题考查主语从句的引导词；题干中的it做形式主语，真正的主语是主语从句"_______ bike﹣sharing has a future in China"；从句从意思到成分都是完整的，所以选择不担任成分又没有意义的that；故答案选B．
【点评】名词性从句考查的关键是连接词的选用和语序，因此，我们首先要搞清从句的性质，掌握各连接词的用法，在此基础上判断．此外，关注名词性从句用陈述语序．
17．That was the second time that he ________ to this school，and in fact he began to like it the first time he _____ to this school．（ ）
A．came，comes B．had come，came
C．has come，came D．had come，comes
【分析】这所学校，事实上，他第一次来这所学校就开始喜欢上了它．
【解答】答案：B．考查固定句型．句意：那是他第二次来这所学校，事实上，他第一次来这所学校就开始喜欢上了它．That was/is the first time that sb had/have done．是英语的固定句型"这是某人第几次干某事"，加入前边是was，that从句用过去完成时；是is的时候用现在完成时have/has done．
故选：B。
【点评】对于英语中固定句型的考查，需要考生在平时的学习中积累句型，掌握句型，根据句意和句子结构的要求选择合适的句型，然后选出正确的答案．
18．______ you don't like him is none of my business．（ ）
A．What B．Who C．That D．Whether
【分析】你不喜欢他和我无关．
【解答】考查名词性从句． 分析句子可知这是一个主语从句you don't like him，从句中不缺少句子成分，所以用that来引导，what，who，引导主语从句，连接词在从句中都要做成分；whether引导意思是"是否"，故选：C。
【点评】名词性从句一直是高考考查的热点，主要考查在具体语境中对what和that的辨析，此外，也要求学生对定语从句和名词性从句有清晰的辨认． 首先我们要判断它是哪个名词性从句．名词性从句是主句的一部分，可以充当主语、宾语、表语、同位语．
19．It suddenly occurred to him he had left his keys in the office．（ ）
A．that B．what C．where D．which
【分析】他突然想起他将钥匙忘在办公室里了．
【解答】答案：A．根据句意和结构可知这句话使用it作形式主语，这个空引导主语从句，主语从句中不缺成分，意思也是完整的，用that引导主语从句．故选A．
【点评】本题考查名词性从句，首先判断属于哪种名词性从句，再判断从句缺少什么成分，如果缺少主宾表，用what，不缺少成分和意思用that，缺少疑问词根据句意判断．
20．﹣What made her mother so angry？
﹣______the exam．（ ）
A．because she didn't pass
B．Her not pass
C．That she didn't pass
D．Because her no passing
【分析】﹣﹣﹣什么让她妈妈这么生气？
﹣﹣﹣她考试不及格．
【解答】答案：C
根据问句可知，要回答一件事情．所以答句是一个省略句型，即"她考试不及格这件事情让她妈妈很生气．"故完整句子为"That she didn't pass the exam made her mother so angry"．其中That she didn't pass the exam这部分是句子的主语，为主语从句，that没有意思，只起到链接的作用，故答案为C．
【点评】考查主语从句以及省略．考生在答题时要分清考查的知识点，先把句子补充完整，在结合具体语境做出选择．
21．You oughtn't to have gone out without a coat yesterday．It wasn't surprising ______you caught a cold．（ ）
A．whether B．that C．how D．why
【分析】你昨天本不应该没有穿外套就出去了．你感冒不奇怪．
【解答】答案为B．本题考查名词性从句中引导词的运用．题干第二句中it为形式主语，空格后面是主语从句，从句从意思到成分都是完整的，所以选择不担任成分又没有意义的that；故选B．

A．That B．What C．Which D．Whether
【分析】宿迁赢得全国文明城市的称号使人们非常兴奋．
【解答】答案 A．
分析句子的结构可知，整个句子的谓语动词为"made"，之前的成分为主语，主语从句中句子结构已完整，意思也完整，因此用连词"that"引导主语从句，"that"在句中不充当成分，也无意义，只起连接词的作用，因此A项符合语境，
故选：A。
【点评】用从属连词that引导的主语从句，例如：
That we shall be late is certain．
That the driver could not control his car was obvious．
但是在一般情况下，往往使用先行it结构，即用it作形式主语，而把that从句放到后面，这时，在口语中，连词that有时则可以省略．所以上述两句可以改为：It is certain that we shall be late．
It was obvious that the driver could not control his car．
常使用先行it结构，用that从句作主语的句子有下列几个句型：
1、It + be + 形容词 + that从句：
It is clear that he was telling the truth．
It's probable that we'll be a little late．
2、It + be + 名词词组 + that从句：
It's a pity that you can't go with us．
3、It + 及物动词 + 宾语 + that从句：
It worried her a bit that her hair was turning grey．
It shocked me that Peter didn't tell anybody where he was．
4、It + be + 过去分词 + that从句：
It is said that he has been there many times．
5、It + seem/happen/appear等不及物动词 + that从句：
It seems that he has lost something．
第二类，用连接代词who、whose、which、what，连接副词when、where、how、why，以及连词whether（或if）引导的主语从句，例如：
Who was responsible for the accident is not yet clear．
→ It is not yet clear who was responsible for the accident．
What he did is not yet known．
→ It is not yet known what he did．
Whether it is true remains a problem．
→ It remains a problem whether / if it is true．
第三类，用what、whatever、where、wherever、whoever、whichever等代词引导的主语从句，例如：
What he said at the meeting encouraged everyone．
Whoever fails to see this will make a big blunder．
这类从句一般相当于带有定语从句所修饰的名词词组，即在结构上相当于一个名词加上一个定语从句，例如：
What he wants to buy is a ten﹣speed bicycle．
→ The thing that he wants to buy is a ten﹣speed bicycle．
Whoever breaks the law is sure to be punished．
→ Anyone who breaks the law is sure to be punished．
14．It is well known _____Confucius was born in the city of Qufu in Shandong province，China．（ ）

【解答】本题考查主语从句中的引导词；题干中考查句型"It is well known that…众所周知"，其中it 为形式主语，that引导了主语从句；本题中主语从句"Confucius was born in the city of Qufu in Shandong province，China"从意思到成分都是完整的，所以选择 在名词性从句中不担任成分、无意义that，除了在宾语从句中之外，that不可以省略；故选：C。
【点评】名词性从句考查的关键是连接词的选用和语序，因此，我们首先要搞清从句的性质，掌握各连接词的用法，在此基础上判断．此外，关注名词性从句用陈述语序．
15．________ the weather will not clear up until next week is bad news for us．（ ）
A．As B．If C．Whether D．That
【分析】考查主语从句，句意：天气到下周才会晴，这对我们来说是个坏消息．
【解答】答案：D，the weather will not clear up until next week 天气到下周才会晴，这是事实，所以排除B和C选项，此句作主语，排除A选项，as不引导主语从句，此句是完整句子，不缺少句子成分，所以用that．引导主语从句，that在从句中不作成分，无含义．
【点评】弄清句子结构，理清连接词的含义及功能．
16．It is obvious _________bike﹣sharing has a future in China．（ ）
A．what B．that C．where D．if

C．That she didn't pass
D．Because her no passing
【分析】﹣﹣﹣什么让她妈妈这么生气？
﹣﹣﹣她考试不及格．
【解答】答案：C
根据问句可知，要回答一件事情．所以答句是一个省略句型，即"她考试不及格这件事情让她妈妈很生气．"故完整句子为"That she didn't pass the exam made her mother so angry"．其中That she didn't pass the exam这部分是句子的主语，为主语从句，that没有意思，只起到链接的作用，故答案为C．
【点评】考查主语从句以及省略．考生在答题时要分清考查的知识点，先把句子补充完整，在结合具体语境做出选择．
