答案及解析：
1．China's first self-designed modern bridge reopened to the road traffic, of which we Chinese were so proud when it was built 50 years ago.
【解析】考查定语从句。句意：中国第一座自行设计的现代化大桥重新通车。当它50年前建成时，我们中国人为它感到骄傲。分析句式结构可知，可把第二句用作定语从句，用关系代词which替代介词of后面的it，变成of+which引导的定语从句，修饰先行词modern bridge。故答案为China's first self-designed modern bridge reopened to the road traffic, of which we Chinese were so proud when it was built 50 years ago。
2．It was not until I finished reading the first English novel that I discovered the beauty of English.
【解析】考查强调句。句意：直到我读完第一本英语小说，我才发现英语的美丽。根据didn’t可知，时态是一般过去时。根据提示，此处是对until I finished reading the first English novel进行强调，句子结构是：It was not until +被强调部分+that…。故答案为It was not until I finished reading the first English novel that I discovered the beauty of English.
3．The writer and his novel that you have just talked about are really well-known.
【解析】考查定语从句。句意：这位作家和他的小说都很有名。你刚刚谈到了它们。 分析句式结构可知，把第二句当做定语从句，用关系代词替代them作介词about的宾语。把第一句的The writer and his novel当做先行词，且作介词about的宾语，因为既有人又有物，所以关系代词用that。故答案为The writer and his novel that you have just talked about are really well-known。
4．Is the computer software they use familiar to you
【解析】考查形容词短语辨析。句意：你对他们使用的计算机软件熟悉吗？be familiar to意为“为…所熟悉”，be familiar with意为“熟悉”，所以二者相转换时，需要交换主语。当be familiar to的时候，主语应为“物”，此处应为电脑软件，为第三人称单数，所以be动词也要改成is。故填“Is the computer software they use familiar to you ”。
5．It is the third time that she has won the race, which has surprised us all.
【解析】考查定语从句。句意：这是她第三次赢得比赛，这使我们大家都感到吃惊。此处可改为非限制性定语从句修饰上文整个句子，从句中缺少主语，应用关系代词which引导。故改为It is the third time that she has won the race, which has surprised us all.
6．which
【解析】考查定语从句。句意：那的路况证明是很好的，而且超出我们预料。原句为and连接两个并列句，同义句转换后，可以变成which引导的非限制性定语从句指代前面的主句，并且在定语从句中充当主语。故填which。
7． having been defeated
【解析】考查非谓语动词。句意：她当场承认她被打败了。分析句子结构及根据句意，可知此处考查的是动词短语acknowledge doing sth.（承认做了某事）；而且“被打败”发生在动词“承认”之前，所以要用动名词的完成式。故填having been defeated。
8．He is a man of great experience, from whom much can be learned.
【解析】考查定语从句。句意：他是一个经验丰富的人，从他身上可以学到很多东西。在“介词+关系代词”引导的定语从句中，先行词指物时，关系代词只能用which，先行词指人时，关系代词只能用whom，分析句子可知，此处主句应为He is a man of great experience，此处的先行词为a man，指人，故此处的关系代词用whom，在从句中作介词的宾语，learn from sb“从某人学得”此处介词应为from，因此完整表达为He is a man of great experience, from whom much can be learned.。故答案是He is a man of great experience, from whom much can be learned.。
9．appealed to
【解析】考查固定搭配和时态。句意：另一方面，这个想法吸引了他。attracted意为“吸引”，与固定搭配appeal to同义，且句子用一般过去时，故填appealed to。
10．Nanche Ancient Village, where I stayed with my family last year, has unique scenery.
【解析】考查定语从句。句意：南社古村落风景独特。去年我和家人住在那里。分析句子可知，我们可以把题干的两个句子合并为一个非限制性定语从句，“Nanche Ancient Village”作主语，“where I stayed with my family last year”为“where”引导的从句修饰先行词“Nanche Ancient Village”，“Nanche Ancient Village”在从句中作地点状语，“has”作谓语，“unique scenery”作宾语。故答案是Nanche Ancient Village, where I stayed with my family last year, has unique scenery.
11．There is no scientific proof for the idea that time travel is possible.
【解析】考查同位语从句。句意：没有科学证据证明时间旅行是可能的。根据句意以及用同位语从句改写要求可知，原句可改写为用that引导的同位语从句，对先行词idea进行补充解释说明。故可改写为：There is no scientific proof for the idea that time travel is possible。
12．I was given three books on cooking, the first of which I really enjoyed.
【解析】考查定语从句。先行词是three books，“头一本”用the first of表示，先行词在定语从句中做介词的宾语，指代物，用which引导，故合并为I was given three books on cooking, the first of which I really enjoyed.
13． the results of the examination to me
【解析】考查双宾语结构。句意：他把考试结果电报给我。分析句子结构和意思可知，这里考查动词wire后面跟的双宾语结构wire sb. sth.=wire sth. to sb.，表示“电报给某人某事”的意思。故答案为the results of the examination to me。
14．had witnessed the accident
【解析】考查过去完成时。句意：许多人说他们是这起事故的目击者。“他们是这起事故的目击者”与“他们目击了这场事故”同义，“他们目击了这场事故”为宾语从句，“目击”为动词witness，“这场事故”为the accident，由主句said，从句用过去完成时，故填had witnessed the accident。
15．It was not until the early 19th century that his musical gift was fully recognised.
【解析】考查强调句。句意：他的音乐天赋直到19世纪初才得到充分的认可。强调句的句型形式“it is…that…”，可以用来对需要强调的成分进行强调。分析句子，本句强调的成分是时间，所以可以改成“It was not until the early 19th century that…”。故填It was not until the early 19th century that his musical gift was fully recognised.。
16．Later I wrote a letter of gratitude to the British gentleman, from whom I got lots of help during my stay in London.
【解析】考查定语从句。句意：后来我给这位英国绅士写了一封感谢信。我在伦敦期间得的很多帮助。根据句意可知，可以把第二句改成定语从句，用关系代词whom代替him作介词from的宾语，这样两句就合并为from+whom引导的非限制性定语从句修饰先行词 British gentleman。故答案为Later I wrote a letter of gratitude to the British gentleman, from whom I got lots of help during my stay in London。
17．atmosphere
【解析】考查名词。句意：我喜欢新年的欢快氛围。原句中tone为名词，意为“曲调，氛围”，可以替换为名词atmosphere，意为“氛围”，在句中作宾语。故填atmosphere。
18． which is because
【解析】考查非限制性定语从句，表语从句。句意：他没有吃早饭，因为停电了。原句为because引导的原因状语从句，同义句转换后，可用which引导非限制性定语从句指代主句“没有吃早饭”这件事，并在定语从句中充当主语；此时because引导的原因状语从句转换为表语从句，在定语从句中充当表语；定语从句的时态应为一般现在时，表示对情况的客观分析。故填which is because。
19． of whose
【解析】考查定语从句。句意：家长们正在改变他们以前的教育方法，他们开始意识到这些方法的负面影响。根据句意分析句子可知，逗号后的句子是“介词+关系代词引导的非限制性定语从句”，其中介词的选择要根据后面的be aware来确定用of，“be aware of”意思是“意识到”，所以第一空格处要填of。根据原句的意思，该句中的关系代词应该在从句中作定语修饰negative effect且翻译为“它们的”，所以第二空格处要填whose。故第一空填of，第二空填whose。
20．He was feeling bad, but he went to work and tried to concentrate.
【解析】考查连词。句意：他感觉很糟糕。然而，他去上班了，并且尽力集中精神工作。此处将原句中的副词however换成表示转折关系的连词but，将两个句子合并成一个句子。故答案是He was feeling bad, but he went to work and tried to concentrate.。
21．The question you are asking is the only one that hasn’t been answered.
【解析】考查定语从句。句意：你在问一个问题。这个问题是唯一一个没有回答的问题。分析句子可知，a question为从句的先行词，在从句中作主语，并且前面有the only修饰，应用that连接，故合并为The question you are asking is the only one that hasn’t been answered.
22． realize your dream come true
【解析】考查部分倒装和固定短语。only修饰句子的状语位于句首时，句子要用部分倒装。把情态动词can提到主语之前，后面的动词用动词原形，realize one’s dream实现某人的梦想，come true实现，所以填realize your dream；come true。
23． The instant as soon as
【解析】考查时间状语从句。这里含有一个时间状语从句，表示“一……就”，可以用The instant或as soon as引导该从句，所以填The instant；as soon as。
24．The moment I see##The instant I see##Immediately I see##Instantly I see##On seeing##Upon seeing
【解析】考查固定句式。句意：我一看到杰克，我就告诉他这个好消息。句式“一……就……”的表达有as soon as, the moment, the instant, immediately和instantly。除了这几个常用表达之外，也可以用介词+动名词的方式来表达以上的含义，介词有on或者upon。短语on seeing him就相当于as soon as I see him。故填The moment I see /The instant I see / Immediately I see/ Instantly I see / On seeing / Upon seeing。
25．The manager of the company is trying to create an easy atmosphere, where the employees can work happily.
【解析】考查定语从句。句意：公司经理正在努力营造一种轻松的氛围，让员工可以愉快地工作。两个句子的共同部分是atmosphere，而in the atmosphere在第二个句子中充当地点状语。两个句子合并为含非限定性定语从句的主从复合句时，主句是The manager of the company is trying to create an easy atmosphere；atmosphere是先行词，且充当从句状语，所以从句应用关系副词where引导，合并后删除第二个句子的in the atmosphere，即从句为where the employees can work happily。故合并为：The manager of the company is trying to create an easy atmosphere, where the employees can work happily.
26． being displayed
【解析】考查时态语态。句意：最新款式在汽车展上展出。on display为固定搭配，意为“正在展览”，最新车型与展出为逻辑上的被动关系，用被动语态，且表示正在展出，用现在进行时的被动语态。故填being displayed。
27．resulted in
【解析】考查固定短语及一般过去时。句意：大雾造成了航班延误。result in意为“造成”，根据句意可知，空前的“大雾”造成了空后的“航班延误”。因此result in符合题意，发生在过去用一般过去时，故用result的过去式。故填resulted in。
28．I wish to thank Professor Smith, without whose help I would never have got this opportunity.
【解析】考查定语从句。句意：我要感谢史密斯教授。没有史密斯的帮助，我不可能得到这个机会。分析句子可知，先行词是Professor Smith，在从句中应该用作定语，故用whose引导，故合并为I wish to thank Professor Smith, without whose help I would never have got this opportunity.
29．I’ve never heard of the people and things that you talked about just now.
【解析】考查定语从句。句意：我从来没听说过这些人和事。你刚才谈到了他们。分析句子结构，主句为I’ve never heard of the people and things，将第二句话变为定语从句，先行词是the people and things，在定语从句中作about的宾语，先行词中既有人也有物，需用关系代词that引导。故答案是I’ve never heard of the people and things that you talked about just now.。
30． What surprised
【解析】考查主语从句。句意：令人惊讶的是，仅仅几周后，她就发现自己可以在课堂上发言了。原句中it为形式主语，that引导主语从句，此处转换成“主语从句+系动词+表语从句”，主语从句使用“主语+ 谓语+宾语+宾语补足语”结构，从句缺少主语，用what引导，表示“人的感受”应用-ed结尾的形容词surprised作宾语补足语；整个句子的谓语动词为was； that she found herself speaking up in class after just a few weeks为表语从句。故填①What②surprised。

【解析】考查非限制性定语从句，表语从句。句意：他没有吃早饭，因为停电了。原句为because引导的原因状语从句，同义句转换后，可用which引导非限制性定语从句指代主句“没有吃早饭”这件事，并在定语从句中充当主语；此时because引导的原因状语从句转换为表语从句，在定语从句中充当表语；定语从句的时态应为一般现在时，表示对情况的客观分析。故填which is because。
19． of whose
【解析】考查定语从句。句意：家长们正在改变他们以前的教育方法，他们开始意识到这些方法的负面影响。根据句意分析句子可知，逗号后的句子是“介词+关系代词引导的非限制性定语从句”，其中介词的选择要根据后面的be aware来确定用of，“be aware of”意思是“意识到”，所以第一空格处要填of。根据原句的意思，该句中的关系代词应该在从句中作定语修饰negative effect且翻译为“它们的”，所以第二空格处要填whose。故第一空填of，第二空填whose。
20．He was feeling bad, but he went to work and tried to concentrate.
【解析】考查连词。句意：他感觉很糟糕。然而，他去上班了，并且尽力集中精神工作。此处将原句中的副词however换成表示转折关系的连词but，将两个句子合并成一个句子。故答案是He was feeling bad, but he went to work and tried to concentrate.。
21．The question you are asking is the only one that hasn’t been answered.
【解析】考查定语从句。句意：你在问一个问题。这个问题是唯一一个没有回答的问题。分析句子可知，a question为从句的先行词，在从句中作主语，并且前面有the only修饰，应用that连接，故合并为The question you are asking is the only one that hasn’t been answered.
22． realize your dream come true
【解析】考查部分倒装和固定短语。only修饰句子的状语位于句首时，句子要用部分倒装。把情态动词can提到主语之前，后面的动词用动词原形，realize one’s dream实现某人的梦想，come true实现，所以填realize your dream；come true。
23． The instant as soon as
【解析】考查时间状语从句。这里含有一个时间状语从句，表示“一……就”，可以用The instant或as soon as引导该从句，所以填The instant；as soon as。
24．The moment I see##The instant I see##Immediately I see##Instantly I see##On seeing##Upon seeing
【解析】考查固定句式。句意：我一看到杰克，我就告诉他这个好消息。句式“一……就……”的表达有as soon as, the moment, the instant, immediately和instantly。除了这几个常用表达之外，也可以用介词+动名词的方式来表达以上的含义，介词有on或者upon。短语on seeing him就相当于as soon as I see him。故填The moment I see /The instant I see / Immediately I see/ Instantly I see / On seeing / Upon seeing。
25．The manager of the company is trying to create an easy atmosphere, where the employees can work happily.
【解析】考查定语从句。句意：公司经理正在努力营造一种轻松的氛围，让员工可以愉快地工作。两个句子的共同部分是atmosphere，而in the atmosphere在第二个句子中充当地点状语。两个句子合并为含非限定性定语从句的主从复合句时，主句是The manager of the company is trying to create an easy atmosphere；atmosphere是先行词，且充当从句状语，所以从句应用关系副词where引导，合并后删除第二个句子的in the atmosphere，即从句为where the employees can work happily。故合并为：The manager of the company is trying to create an easy atmosphere, where the employees can work happily.
26． being displayed
【解析】考查时态语态。句意：最新款式在汽车展上展出。on display为固定搭配，意为“正在展览”，最新车型与展出为逻辑上的被动关系，用被动语态，且表示正在展出，用现在进行时的被动语态。故填being displayed。
27．resulted in
【解析】考查固定短语及一般过去时。句意：大雾造成了航班延误。result in意为“造成”，根据句意可知，空前的“大雾”造成了空后的“航班延误”。因此result in符合题意，发生在过去用一般过去时，故用result的过去式。故填resulted in。
28．I wish to thank Professor Smith, without whose help I would never have got this opportunity.
【解析】考查定语从句。句意：我要感谢史密斯教授。没有史密斯的帮助，我不可能得到这个机会。分析句子可知，先行词是Professor Smith，在从句中应该用作定语，故用whose引导，故合并为I wish to thank Professor Smith, without whose help I would never have got this opportunity.
29．I’ve never heard of the people and things that you talked about just now.
【解析】考查定语从句。句意：我从来没听说过这些人和事。你刚才谈到了他们。分析句子结构，主句为I’ve never heard of the people and things，将第二句话变为定语从句，先行词是the people and things，在定语从句中作about的宾语，先行词中既有人也有物，需用关系代词that引导。故答案是I’ve never heard of the people and things that you talked about just now.。
30． What surprised
【解析】考查主语从句。句意：令人惊讶的是，仅仅几周后，她就发现自己可以在课堂上发言了。原句中it为形式主语，that引导主语从句，此处转换成“主语从句+系动词+表语从句”，主语从句使用“主语+ 谓语+宾语+宾语补足语”结构，从句缺少主语，用what引导，表示“人的感受”应用-ed结尾的形容词surprised作宾语补足语；整个句子的谓语动词为was； that she found herself speaking up in class after just a few weeks为表语从句。故填①What②surprised。
