高三英语新高考复习公开课第十章名词性从句课件

第十章名词性从句英语中，名词充当的句子成分主要有主语、宾语、表语、同位语。然而，在实际运用中，如果这些成分仅仅用名词去充当的话往往不够用，为更加准确地表达出句子的意思，通常用一个句子去充当这些成分，于是便产生了名词性从句。与句子成分相对应，名词性从句也包括主语从句、宾语从句、表语从句和同位语从句。

Acomputercanonlydo________youhaveinstructedittodo.【解析】what引导宾语从句，并在从句中作宾语，表示“一台电脑只能做你指示它去做的事情”。what高三英语新高考复习教学PPT-第十章名词性从句精品ppt课件-PPT执教课件【推荐】高三英语新高考复习教学PPT-第十章名词性从句精品ppt课件-PPT执教课件【推荐】例3

Choosingtherightdictionarydependson________youwanttouseitfor.

【解析】what引导的名词性从句作介词on的宾语，what在从句中又充当介词for的宾语，表示“你想用它做什么”。what高三英语新高考复习教学PPT-第十章名词性从句精品ppt课件-PPT执教课件【推荐】高三英语新高考复习教学PPT-第十章名词性从句精品ppt课件-PPT执教课件【推荐】(2)复合疑问连接代词whatever,whoever,whichever等引导的名词性从句，意义为“无论什么”“无论谁”“无论哪一个”或“任何东西”“任何人”“任何一个”等，可以变成相应的定语从句。Whoeverleavestheroomlastoughttoturnoffthelights.任何最后离开房间的人应关灯。＝Anyonewholeavestheroomlastoughttoturnoffthelights.例4翻译：一般认为给小孩子任何他想要的东西是不明智的。Itisgenerallyconsideredunwisetogiveachild________heorshewants.whatever高三英语新高考复习教学PPT-第十章名词性从句精品ppt课件-PPT执教课件【推荐】高三英语新高考复习教学PPT-第十章名词性从句精品ppt课件-PPT执教课件【推荐】3.连接副词：连接副词在从句中作状语。连接副词在起连接句子作用的同时，还起到副词的作用CouldyoutellmewhereMrWhitelives?你能告诉我怀特先生住在哪儿吗？4.it在名词性从句中的用法(1)it作形式主语由于主语从句位于句首，句子显得头重脚轻，因此常把它移到后面，句首用it来作形式主语。Whetherhewillcomeornotisstillunknown.＝Itisstillunknownwhetherhewillcomeornot．it作形式主语的4个常见句型：①Itis＋形容词＋that从句Itisstrangethathedidn'tcomeyesterday．②Itis＋名词词组＋that从句Itisapitythatwecan'tgothere．③Itis＋过去分词＋that从句Itisreportedthatthreepeoplewerekilledinthetrafficaccident．④It＋动词＋that从句Itdoesn'tmatterwhetherhe'llcomeornot．例5

Itisknowntous________wherethereispollution,thereisharm.【解析】句意：众所周知，哪里有污染，哪里就有危害。it为形式主语，后面的主语从句wherethereispollution,thereisharm结构和意思都完整，填只起连接作用，在从句中不充当任何成分的that。that例6

________wasapitythathemissedthechancetotakepartinthecontest.【解析】此题考查it作形式主语的用法。根据句子结构可知，that引导的从句为主语从句，作真正主语，因此前面应有形式主语，而形式主语只能用it。“很遗憾他错过了参加比赛的机会。”Finally(2)it作形式宾语如果宾语从句后面有宾语补足语，则用it作形式宾语，将从句后置。Wemustmakeitclearthatanyonewhobreaksthelawwillbepunished．5.同位语从句与定语从句的区别Thenewsthathegotthefirstprizeissurprising.(同位语从句)Thenewsthatyou'veheardisn'ttrue.(定语从句)①同位语从句中的that是连词，在从句中不充当任何句子成分；定语从句中的that除了起连接作用外，还在句子中充当一定的句子成分，如例句中的that就在句子中充当宾语。②从语义上来看，同位语从句与先行词是等同关系，一个具体，一个抽象，如例句中的先行词news和从句thathegotthefirstprize,news的具体内容就是thathegotthefirstprize。而定语从句中的从句是修饰先行词的，如例句意思为“你听到的消息”。例7

Iamdelightedtohearthenews________youhavepassedthedrivingtest.【解析】that引导同位语从句，解释说明前面抽象名词news的具体内容。Finally用适当的连词、连接代词或连接副词填空。1.________hedoeshasnothingtodowithme.2.Ihavenoidea________ornothehasfinishedthework.3.________theboydidn'ttakemedicinemadehismotherangry.4.Oneofthemenheldtheview________whatthebooksaidwasright.5.Thatis________helikestheplacesomuch.6.Thatis________LuXunoncelived.What
