【答案】C
【解析】【分析】句意：——是什么让她对她自己感到羞愧？——是她获得了她班上的最低分让她惭愧。A中的what是句子的主语，但是because引导的从句不作主语，是原因状语从句，故排除；B的第一空是错误形式，故排除；C、D两项的第一个选项是一样的，说明第一个题干是一个强调句型，特殊疑问句下的强调句型，有what引导；第二个空是对what的回答，因为what是上一句的主语，That she got the lowest mark in her class是从句，可以作主语；而D项的get是动词原形，不能作主语，故答案为C。
【答案】B

【答案】C
【解析】【分析】题意：--你正在找什么？--我的钥匙。我不记得我放在什么地方了。考查宾语从句。特殊疑问句做宾语从句应用陈述语序：特殊疑问词+主语+谓语+其他。where什么地方，故选C。

1．连接词that，whether引导①That the college will take in more new students this year is true．今年这所大学将招收更多新生是真的。

②Whether he can finish his task on time is of great importance．他是否能按时完成任务非常重要。

【注】(1)if不能引导主语从句。

(2)形式主语it替代主语从句。

常见的it替代主语从句的句式主要有以下几种：A．It+系动词+形容词+that从句。

如：It is quite clear that the whole project is doomed to failure．很清楚，整个计划注定要失败。

B．It+系动词+名词+that从句。

如：It is our hope that the two sides will work towards peace．我们的希望是双方能朝着和平的方向发展。

名词性从句做题技巧

名词性从句做题技巧

名词性从句做题技巧主语从句、宾语从句、表语从句和同位语从句统称为名词性从句规律一：名词从句中须使用陈述语序！规律二：特别注意虚拟语气的采用！关键词是suggest,suggestion,order,advice,proposal等动词或名词时,后面的从句用”(should)+动词原形”.should可省略.规律三：在主语，表语，同位语从句中一般只使用whether,只有在宾语从句中whether等于if4种情况须要“与否”时，就可以用whether：（1）whether坐落于句子结尾；（2）whether前面存有介词；（3）whether后紧随ornot4）鼓励未来式从句和同位语从句规律四：主从和宾从常用“it”作形式主语或宾语。

需记住某些常见句型：itisimportantthat…itisapitythat…itissaidthat…sbthink/makeitnecessarythat…规律五：名词从句中，如果发生谓语doubt/wonder/notsure/uncertain，则需以疑问词what,why/who/if/whether…，如果发生谓语notdoubt/know/sure，则用that….ihavenodoubtthat…thereisnodoubtthat…iknow/amsure/that….idoubt/don’t knowif/where/whether…规律六：what,whatever,whoever,whomever,在名词性从句中起至两重促进作用.即为在主句和从句中都作成分,因此，当主句和从句都失成分时，可以考量采用。

而that就可以REBOOT名词性从句中作连接词促进作用，不并作从句中的成分。

规律七：名词从句作主语时,谓语一般用单数.从句中即使有两个疑问词,但只有一个动词时,谓语也用单数.但是如果有两个动词,则谓语用复数,不定式作主语时也是如此.规律八：主语从句放在句首时，在从句中起连接作用的that不能省略。

名词性从句答题注意事项-精品PPT课件


扫清盲点 ①从属连词 that/if/whether 不作成分； 而连接副词 when, where 等在从句中作状语。 ②引导名词性从句且在从句中作主语、 宾语、表语时用 what, who, which，要注意意 义差别。 ③名词性从句中 that 引导主语从句、表 语从句或同位语从句时不能省略。
技巧 2 句意语境巧解题 有些引导词在句中有很鲜明的意义，如 if“如果”， whoever“ 无 论 谁 ” ， whatever“ 无 论 什 么 ” ， because“ 因 为”，why“为什么”等。结合句意翻译和语境，不难解决这 类试题。 3．牢记 what 和 that 的区别 ①that 没有词义，也不作任何成分，当从句意义完整，不 缺任何成分时用 that； ②what 在从句中表示“……的(东西)”(有时候可以不 译)，在从句中充当主语、宾语、表语、定语等成分。
答题微点 1.确定是名词性从句 设空处无提示词，先确定主句主谓结构； 再确定设空和设空后的内容在主句中充当主 语、宾语、表语或同位语。
2．利用 2 个技巧搞定名词性从句 技巧 1 分析句子成分 ①缺少主语、宾语、表语：用连接代 词 what, who, whom, which, whatever, whose 等。 ②缺少状语(结合句意判断)：用连接 副 词 where( 表 地 点 ),缺成分，句意缺少“是否”：用 if/whether。 ④不缺成分且句子意义完整：用 that。
