A 50.A【解析】1.答案B，系动词后为表语，所以此处is后面是表语从句，在从句中不缺少成分，所以可以加上状语，D选项不能引导表语从句，which和what作主语、宾语、表语，不作状语，Where做状语．选B．考查表语从句，句意：纸厂就是纸被制造的地方．先确定从句类型，在找连接词．2.C 考查名词性从句．本句是一个表语从句，that's because…是英语的固定说法"那是因为…"所以用because 来引导．how如何；why为什么；when什么时间．根据句意：那是因为他当时没钱．所以答案选C．虽然那辆车很便宜，但他没有买那辆车，那是因为他当时没钱．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察在具体语境中对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，3.B 考查名词性从句．根据句意：问题是我们是否应该向他们求助．whether引导表语从句表示"是否"．if不能引导表语从句，在名词性从句中if 只能引导宾语从句．本从句是一个表语从句，所以答案选B．．问题是我们是否应该向他们求助．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察在具体语境中对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，4.答案：A 考查定语从句．经过分析句子结构可知，这个句子中包含了一个定语从句和一个表语从句．在定语从句中，关系词指物，并且在定语从句中作宾语，故用that；在表语从句中，表语从句中的引导词在从句中作时间状语，故用when．故选A．雷欧永远不会忘记的时刻是格林先生就如何提高写作水平给了他许多宝贵的建议．定语从句又称为形容词性从句，综观历年高考试题，我们可以发现该语法项目是测试中的热点与难点，解定语从句的题目首先要知道哪一句是主句，哪一句是从句，被修饰的词是谁，从句中的句子成分缺失什么，根据缺失成分的不同从而选出相对应的关系代词或者关系副词，从而选出正确的答案，解题的关键是从句句子的成分分析．5.答案是A．考查名词性从句，分析句子结构"________ she couldn't understand"是一个主语从句，从句中缺少understand的宾语，所以用what引导，what做从句的宾语；fewer and fewer students showed interest in her lessons是一个表语从句，根据句意：她不能理解的是为什么越来越少的学生对她的课表现出兴趣，所以用why来引导．故答案选A．她不能理解的是为什么越来越少的学生对她的课表现出兴趣．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察在具体语境中对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，那么就找到了解题的路子．名词性从句的解题可以从分析从句的句子结构开始，看从句是否缺少主语、宾语、表语、定语等句子成分．然后具体问题具体分析．6.答案为A．本题考查名词性从句中引导词的运用．题干空格后面是be 动词后面的表语从句，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；that在表语从句中仅仅起着结构上的作用，但是不能省略，答案选择A．B项whether表示"是否"，不符合题意；C项which表示选择"哪一个"，并且在从句中要担任成分，所以不符合题意；D项what表示选择"所，什么"，并且在从句中要担任成分，所以不符合题意；Crystal变得如此出名的一个原因是他的思维快．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．7.答案：A．本句考查倍数的表达法．倍数可以用倍数+what从句来表达．如：The production is now three times what it was ten years ago．现在的产量是十年前的三倍．这里 what相当于the production that，故选A．电视生产商的产能比以前高多了．今年的产量是五年前产量的三倍．本题考查倍数表示法．英语中倍数的表示法有三种：倍数+as…as…；倍数+比较级+than；倍数+thesize/length/weight/wideth/height of．学习时，要注意区分和掌握．8.答案为D．本题考查从句中引导词的选择．题干中第一空格后面是修饰和限制名词thing的定语从句，把先行词the important thing带入到定语从句，完整的定语从句是"Jane discovered the important thing"；可见the important thing在从句中充当discovered的宾语．定语从句中that可以在从句中做主语或宾语，做宾语的关系词可以省略；所以根据第一空排除A，what不引导定语从句；第二空题干空格后面是be 动词后面的表语从句，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；that在表语从句中仅仅起着结构上的作用，但是不能省略，由此排除B和C，答案选择D．Jane发现的一件重要的事是黑猩猩也猎取并吃肉．本题考查从句的引导词：在分清从句性质的基础上，理解各引导词的用法再做判断．9.答案为A．本题考查名词性从句中引导词的运用．题干空格后面是be 动词后面的表语从句，表语从句中插入了插入语you think；去掉you think发现从句中缺少表语．名词性从句中，what在从句中可以充当表语，由此判断答案是C．B项是连接副词how在从句中表示方式，不做表语，所以不符合题意； C项that连接代词在从句中不能担任成分，所以排除；D项which在名词性从句中表示选择，所以不符合题．我相信世界是你所认为的那样．所以微笑着面对世界世界也会对你微笑．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．10.答案为A．本题考查名词性从句中引导词的运用．题干空格后面是be 动词后面的表语从句，表示"在这个地方你能玩得开心并且获得的不仅仅是开心"；可见从句中缺少的是"在…地方"；名词性从句中where可以在从句中充当地点状语表示"在…地方/方面"，由此判断答案是A．B项是连接副词how在从句中表示方式，不符合题意； C项连接代词在从句中不能充当状语，所以排除；D项that在名词性从句中不担任成分，不表达意思，而本句意思不完整，所以不符合题．欢迎来到上海迪士尼！这是你能玩得开心并且不仅仅获得开心的地方．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．11.答案为B．本题考查名词性从句中引导词的运用．题干空格后面是is 动词后面的表语从句，从句中lie为不及物动词，缺少地点状语表示"在于…地方/方面"．名词性从句中，where在从句中可以充当地点状语，由此判断答案是B．A项表示原因，C项表示方式、D项表示时间，均不符合题意．他很幽默而他的哥哥很严肃．这儿就是他们的区别所在．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．12.答案为D本题考查表语从句．在本句中"____ he shows love and care for me and my family"作为整个句子的表语从句，因为该从句表达意思完整，不缺成分，故应该选关系代词"that"．关于父亲我所珍惜的是他对我以及家人的爱和关心．名词性从句考查重点在关系词的选择．13.答案为C．本题考查名词性从句中引导词、语序和强调句型的综合运用．题干空格后面是be 动词后面的表语从句，从句中缺少的是主语．名词性从句中，what在从句中可以充当主语，而主语what又被强调句型所强调．强调句型的基本结构是"It be+被强调部分+that（被强调的是人可以用who）+其它"．如果被强调的是特殊疑问词，特殊疑问词要放在句首，构成"特殊疑问词+be it that+其它"，本题中被强调的是what，所以结构是"What is it that…"．本句是名词性从句中的表语从句，必须用陈述语序，因此陈述语序为"what it is that"，由此判断答案是C．众所周知，态度就是高度．我们的态度就是我们生活中改变一切的事物．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．14.答案D．考查名词性从句．分析句子可知表语从句"_______ makes everything run smoothly"句中缺少主语，所以用what引导表语从句，how 引导表语从句只能在句中做状语，which可以做主语但是意义是"哪一个"，that在表语从句中不做任何的成分只起连接作用，故答案选D．一个国家的基础设施使一切顺利．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察在具体语境中对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，15.答案：B分析句式可知，"______ he has enough time"放在is后面是一个表语从句，根据句意填whether，意思"是否"；if不能用来引导表语从句．问题是他是否有足够的时间．考生在答题时先分析句子结构，在根据名词性从句知识做出选择，尤其是要知道if不能用来引导表语从句．16.答案A．考查连词．根据句子结构可知，What she couldn't understand 主语从句，"____ fewer and fewer students showed interest in her lessons"为表语从句，从句中缺少原因状语．根据句意：她无法理解的是，为什么越来越少的学生对她的课感兴趣．所以用why来引导，答案选A．她无法理解的是，为什么越来越少的学生对她的课感兴趣．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察在具体语境中对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，17.答案：B．分析句子的结构可知，be动词was后面为一个完整的句子I was ill，所以用that来引导，因为本句的主语就是The reason，所以再用because来引导表语从句则显得重复，可排除；故选B．--你昨天为什么没有去看电影？--因为我生病了．本题考查表语从句，要会分析句子的成分，并且掌握that引导名词性从句时在从句中不作任何成分．18.答案是A．考查表语从句．句意是：拥有一部智能手机的最大好处就是你能随时随地用它上网，听音乐和拍照．所以用连接词that引导从句．how 怎么，表示方式；what 什么；whether 是否．故选A．拥有一部智能手机的最大好处就是你能随时随地用它上网，听音乐和拍照．解答此类题目，首先要掌握句意，然后分析句型，根据相关语法选择正确的答案．19.B 考查名词性从句．这是一个表语从句，根据句意：我听说你说医生应该得到高薪，这是我不同意的地方．所以用疑问副词where来引导．what是指不同意的内容，why是不同意的原因，故答案选B．我听说你说医生应该得到高薪，这是我不同意的地方．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察在具体语境中对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，20.答案：C题干中the workers held up in that area yesterday will be set free是作系动词的表语，是一个表语从句；从句结构完整，需要知道的是时间，要用连接副词when．故选C．让我们非常关心的是那个地区昨天被绑架的工人什么时候会被释放．在句子中起名词作用的各种从句统称为名词性从句．根据它们在句中的语法作用，这类从句又可分为主语从句、同位语从句、表语从句和宾语从句．21.答案为D．本题考查名词性从句中引导词的运用．题干中空格后面需要的是表语从句，that's when…那就是…的时间；That's how…那就是做…的方式；That's why…那就是…的原因；what在名词性从句中可做主语、宾语、表语或定语，表示"所、什么"，本题的从句中不缺主语、宾语、表语或定语，所以排除what；根据句意，答案是D．--我听说你想要在外国大学进一步深造．--是的．那就是我尽力学好英语的原因．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．22.答案是A．本题考查表语从句中的引导词；题干中is后面的表语从句；that's why那就是…原因；that'when 那就是…时间； that's how 那就是如何…；what在名词性从句中可做主语、宾语、表语或定语，表示"所、什么"，本题的从句中不缺主语、宾语、表语或定语，所以排除what；根据句意，发生事故交通变慢的原因，故答案是A．在主干道上发生了一起车祸．那就是为什么交通突然似乎慢下来的原因．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．23.答案是B．本题考查表语从句中的引导词；题干中is后面的表语从句；that's why那就是…原因；that's where 那就是…地方/方面；that's how 那就是如何…；that's when 那就是…时间；根据句意，那就是我不赞成的方面，故答案是B．--星期天我宁愿把自己关在家里整天上网；--那就是我不赞成的方面．你应该过更活跃的生活．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．24.答案A．题中的____ I don't agree是一个表语从句．从句中的动词agree是一个不及物动词，后面不能直接加宾语．根据句意，这是我不同意的"地方"，在这里指"方式"，故选择where表示抽象的地点状语．故选A．句意：--在星期天我宁愿把自己关在家里，整体听音乐．---那就是我不同意的地方．你本应该有一个更为积极的生活．本题考查表语从句中连接词的使用，要分析表语从句中句子的结构是否完整和结合语境选择出正确选项．25.答案是D．本题考查名词性从句中的引导词．is后面的表语从句中缺少的是like的宾语；how为副词，不做宾语，排除C；that在名词性从句中不担任成分，排除B；which 在名词性从句中表示选择，本题中无选择的含义，排除A；what在名词性从句中可做主语、宾语、表语或定语，表示"所、什么"；故本题选择D．--你为什么喜欢在这家公司工作？--我所喜欢的是友好的氛围．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．26.答案：A根据"arts should serve the people"作为一个完整的句子，用在了系动词is之后，因此该句是表语从句；A．连接词that在表语从句中没有任何意义，只起连接作用，但通常不能省略；B．which 哪一个；C．what通常在表语从句中作主语，宾语和表语；由于从句表达了完整的意思，故选A对于艺术他讲话的一个关键点就是艺术应该为人民服务．本题主要考查了表语从句的用法．做本题时，首先可以根据句子的结构特点，判断出该句为表语从句；其次应熟练掌握表语从句中连接词的用法．例如表语从句中的that虽然不作任何成分，但通常不能省略．27.答案：D．根据The best moment was 说明后面整句是表语从句，而表语从句 I was informed my first book was to be published．根据句意，现在我能记得的最好时刻是当我被告知我的第一本书将被出版．可知句子不完整，缺时间状语，故选D．其中I can now remember 是定语从句现在我能记得的最好时刻是当我被告知我的第一本书将被出版．本题考查表语从句的连接词，在充分分析句型基础上便能选出正确答案．其中I can now remember 是定语从句，可删去不看．故题中从句是跟在"was"后面的，属于表语从句．28.答案：D 根据Teens take risks and while we want to encourage independence，sneaking out at night to hang out with friends or dates isn't 说明后面整句是表语从句，而表语从句parents see as being independent 中句子不完整，缺成分，see…as把…视作，看作，故选D．青少年冒着风险，尽管我们想鼓励独立，晚上偷偷和朋友溜出去闲逛或约会不是父母所视为的独立．本题考查表语从句的连接词，在充分分析句型及了解see…as把…视作，看作，基础上便能选出正确答案．29.答案为D．本题考查名词性从句中引导词的运用．题干空格后面是be 动词后面的表语从句，表示"因为公共汽车在路上出故障"；可见从句中缺少的是"原因"，做状语；名词性从句中because可以引导表语从句说明具体的原因，由此判断答案是D．A项是连接副词why连接的是具体的"结果"，不符合题意； B项that在名词性从句中不担任成分，不表达意思，而本句意思不完整，所以不符合题．C项连接代词what在从句中不能表示原因，做状语，所以排除；你又迟到了．但是这是因为公共汽车在路上出故障了．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．30.答案：D．本题是个并列句，that替代上面的内容，品质，根据 That's可知后面整句是表语从句，而表语从句it takes to do anything successfully句子不完整，缺take的宾语，故选D．坚持是一种品质品质，要做好任何事情都需要有它．本题考查表语从句的连接词，在充分分析句型基础上便能选出正确答案．31.强调句型的特殊疑问句形式为：特殊疑问词+be +it+ that+其它？第一个空是考查强调句型的特殊疑问形式，故填what；第二个空是表语从句，表语从句中缺少he is的表语，故填what。

★ The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋。
★ The problem was that it was too valuable for everyday use.问题是它作为日常之用太贵重了。
★ What she couldn’t unde rstand was that fewer and fewer students showed interest in her lessons. 我们不能理解越来越少的学生对他的课不感兴趣。
※ 由关系代词引导的表语从句。
关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever 等引导表语从句，在句中作主语、宾语、表语，关系代词不能省略。
例如：>★ The question is which of us s hould go.问题是我们哪一个应该去。
★ The problem was who could do the work.问题是谁能做这项工作。
★ That's what he is worrying about.那就是他在担心的事。
★ That's what we should do.那是我们应该做的。
※由关系副词引导的表语从句。
关系副词 when, where, how, why 除在句子起连接作用外，在从句中还充当时间，地点，方式或原因状语，本身具有词义。
例如：★Go and get your coat. It's where you left it. 去把雨衣拿来。
就在你原来放的地方。
^★ I had neither a raincoat nor an umbrella. That’s why I got wet through. 我们既没伞也没雨衣，这是我们淋湿的原因。
★ That is how mice ruin many stores of grain every year.那就是老鼠是怎样每年损害大量粮食的。
★ That is wh at he is worried about.那就是他所担心的。
※ 由连词because，as if/as though等引导的表语从句。
★ It looked as if it was going to snow.看起来好像要下雪了。
★ That's because we never thought of it.这是因为我们从未想过此事。
★ It seems as if he didn’t know the answer.好像他不知道答案。
\注意A. 表语从句一定要用陈述语序。
False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B. 不可以用if，而用whether 连接表语从句(as if 例外）。
引导宾语从句时可以互换if/whether 位于介词后要用whether位于句首时要用whether。
引导表语从句，主语从句，同位语从句时要用whether。
…False: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question.C.不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。
Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D. that在表语从句中不可以省掉。
：基本用法表语从句只能置于主句之后，而主句的动词只能是联系动词。
名词性从句在be等系动词后作表语时被称为表语从句例如：★The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。
(how 在表语从句中充当方式状语)★ The scisso rs are not what I need. 这把剪刀不是我所需要的。
(what 在表语从句中充当宾语)'★ What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本。
(what在主语从句中作直接宾语， that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)★ That is what I want to tell you.那就是我想要对你讲的。
(what在表语从句中充当直接宾语)★ That is why she failed to pass the exam. 那就是她考试不及格的原因。
