重难点06 名词性从句
名词性从句是高考常考的语法项目，主要考查对连接词的正确把握。分析历年高考试题不难发现，连接代词what的用法是考查的热点。另外同位语从句中，经常考查that的用法。除此之外，it作形式主语和形式宾语代替主语从句和宾语从句其他连接词的用法以及从句的语序也时有考查。
名词性从句解题三步走
第一步：根据两句之间的意义和逻辑关系，或者根据句式结构判断是否是名词性从句。
第二步：一旦判断是名词性从句，就根据名词性从句中缺少什么句子成分来确定选用什么连接词。若从句中缺少主语、宾语或表语，用连接代词。指物用what，whatever；指人用who，whoever。
第三步：如果不缺少主语或宾语，要看从句是否有疑问。如果没有疑问用that，有疑问则根据句意使用when，where，why，how，whether等。

【易错题01】 主语从句
1.（ 新课标I卷 ）_______is so breathtaking about the experience is the out-of-this-world scenes.
【答案】what
【错误分析】 未能找到主句谓语动词，造成句首It形式主语的错觉。
【解题思路】 考查主语从句。句意为：这段经历让人叹为观止的是那些超凡脱俗的场景。引导主语从句,在从句中作主语,表示"……的东西",故填What.
2.Your support is important to our work . ________ you can do helps.
【答案】Whatever
【错误分析】 未能对句子谓语动词helps作出判断，误以为helps此处为名词。
【解题思路】考査名词性从句。句意:你的支持对我们很需要, 无论你做什么都会有帮助。从句动词do需要宾语,且引导主语从句,故用whatever。
【易错题02】 宾语从句
3（2022年浙江1月）Cobb, for her party, started to ask conference organizers who invited her to speak ______ she could do so remotely.
【答案】if/whether
【错误分析】由于主句被分割主语和谓语，容易造成翻译出错。影响对宾语从句意思的理解。
【解题思路】考查宾语从句。句意：对于她的出席，Cobb开始询问邀请她的组织者是否可以远程进行。显然ask后面出现了一个宾语从句，宾语从句句意不完整，whether/if“是否”符合语境，故填whether或if。
4.（2021年北京卷）The poor woman wasn't able to give him any information about ________ she lived．
【答案】where
【解题思路】考查宾语从句。句意：这个可怜的老妇人不能说清楚她住在哪里。介词about后是宾语从句，根据句意，此处用where“在哪里；……的地方”符合句意，从句中作地点状语，故填where。
5. Over thousands of years，they began to depend less on ______ could be hunted or gathered from the wild，and more on animals they had raised and crops they had sown.
【答案】what
【错误分析】误把介词宾语从句当做介词加which引导的定语从句。设空处前面没有先行名词，非定语从句。
【解题思路】考查名词性从句。句意：在几千年的时间里，他们开始减少对我们从野外采集的猎物的依赖，而更多地依赖他们饲养的动物和播种的庄稼。分析句子，宾语从句部分缺主语，所以引导词应为“连接代词”。根据句意，此处缺“什么”之意。故填what。
【易错题03】 表语从句
6（2021年天津卷）What puzzles Lily's friends is ________ she always has so many crazy ideas.
【答案】why
【错误分析】不能掌握系动词后表语从句，并且对全句的逻辑意思理解不清。
【解题思路】考查表语从句。句意：令Lily的朋友们感到困扰的是她为什么总是有这么多疯狂的想法。分析句子，该空需要一个表语从句的连接词，结合句意，应该是朋友们不明白Lily 为什么有这么多疯狂的想法。所以本句为why引导的表语从句。故填why。
【易错题04】 同位语从句
7.（2019新课标I卷）While they are rare north of 88°，there is evidence ________ they range all the way across the Arctic, and as far south as James Bay in Canada.
【答案】that
【错误分析】不能熟练掌握同位语从句经常修饰的名词，误把从句看作定语从句。
