高中 同位语从句详细讲解与练习(附答案)
同位语从句讲义1．定义：用作同位语的从句叫做同位语从句。

如：They were all very much worried over the fact that you were sick.对你生病这件事，他们都很焦虑。
Where did you get the idea that I could not come?你在哪儿听说我不能来？Early in the day came the news that Germany had declared war on Russia.德国已对俄国宣战的消息一大早就传来了。
注：同位语从句偶尔由从属连词whether引导。
如：I have no idea whether he’ll come or not.我不知道他是否来。
连接代词who, which, what和连接副词where,when, why, how亦可引导同位语从句。

同位语从句讲解及练习含答案
同位语从句讲解与训练一、同位语的概述1. 同位语的定义：一个名词或代词后面有时可跟一名词(或其它形式)，对它作进一步的修饰,限定或说明，说明它是谁，是什么，当两个词或词组在一个句子中具有相同的语法地位而且描述相同的人或事物时，我们称它们为同位语。
同位语与被它限定的词的格要一致,并常常紧挨在一起。
2. 同位语的分类：同位语分限制性和非限制性两种。
限制性同位语和前面的词关系比较密切，之间不能停顿；非限制性同位语与前面的词关系比较疏散，常用逗号隔开。
例如：③Mickey Mouse first appeared in the cartoon Steamboat Willie.米老鼠首次出现在卡通片《威利号汽船》中。
Steamboat Willie就是cartoon的同位语，关系紧密。
④Walt Disney, an rich and successful businessman, created the famous cartoon character----Mickney Mouse. 瓦尔特迪士尼，一个富有而成功的商人，创造出了这个著名的卡通形象----米老鼠。
an rich and successful man 是主语Walt Disney的同位语，句子中有没有它，无所谓，不影响理解。
而且“瓦尔特迪士尼”是个“富有而成功的商人”，反过来，“一个富有而成功的商人”可不一定就是“瓦尔特迪士尼”。
3. 同位语的形式：(1)名词用作同位语时最多：①This is Mr．Brown，our Spanish teacher．这是我们的西班牙语老师布朗先生。
②“Leave it to me，”said Lao He，the man on night duty．值夜班的人老何说：“这事交给我。
”③You girls may take those seats over there．你们姑娘们可以坐在那边的座位上。

同位语从句一、同位语从句概述同位语从句是用以解释说明某一名词内容的从句，常见的可以被同位语从句修饰的名词有：belief，chance,doubt,hope,idea,news,opinion，thought，promise等。
引导同位语从句的词有连词that，whether和副词how，when,where等。
二、同位语从句点拨（1）同位语从句是意义完整的陈述句时，用连词that引导。
注:that在从句中不充当任何成分,只起连接作用,通常不省略.如：I got the news that he would come to see methe next week。
（2）同位语从句是疑问句时，应根据语境选用who，when ，where，how，whether（不能用if）等词来引导.如：The question who is the best for the job requiresconsideration.（3）分隔式同位语从句：当主句的谓语较短，而同位语从句较长时,为了使句子保持平衡，常把同位语从句后置。
如:An idea came to him that he could buy her a diamondring.（4）后面常跟同位语的词有:doubt,fact,hope,idea,message，news,possibility，promise，question，suggestion，truth，thought,warning,wish等。
注:advice，order，suggestion等词表示建议、命令的词后的同位语从句中的谓语动词须用(should）+动词原形。
如：He made the suggestion that the meeting(should）be put off。
三、同位语从句与定语从句的区别（1）所表达的内容不同：同位语从句和定语从句一般是放在某一名词后面,但同位语从句是对该名词的解释和说明,而定语从句是对该名词的修饰,说明它的性质特征.如：The fact that he presented was a strong proof.他所提供的事实是一个强有力的证据。

高中英语新高考一轮语法复习讲义（二十）同位语从句（含真题练习与解析）
高中英语新高考一轮语法复习讲义（二十）同位语从句（含真题练习与解析）2021届高中英语新高考一轮语法复习讲义（二十）同位语从句（含真题练习与解析）同位语从句定语：在复合句中充当主句中某一名词的同位语的从句，叫同位语从句。
功能：一般用来解释或说明这些名词的具体含义或内容。
例如：1) It is a fact that smoking is harmful to everyone.2) I have no idea what you mean.3) There is no doubt that he is lying.(说谎)4）The question who should be the first has not been settled.5)The news that he got the first prize made everyone pleased.点拨：1.同为语从句与位于它之前的抽象名词在主句中起着同样的作用，两者是同等重要的。
如上述1)句中的抽象名词fact 和从属连词that 引导的从句之间就是同位关系。
从结构上说，fact 是主句的表语、that 从句也是主句的表语；从意义上说，that 从句用来说明fact 的具体内容。
2.同位语从句在复合句中的位置较灵活，但它始终跟在与它有着同位关系的抽象名词之后。
因此，只要找到抽象名词，就不难找到同位语从句。
3.我们可以把同为语从句前的这个抽象名词叫先行词，把引导该从句的从属连词叫关系词。
真题演练找出以下复合句中的名词性从句，并说明它们分别属于哪种名词性从句。
1.（2018?江苏.七选五）No doubt the theater hascontributed to the area's development and economic growth.2.【2019·天津单选】The manager put forward a suggestionthat we should have an assistant.

同位语从句一、同位语从句概述同位语从句是用以解释说明某一名词内容的从句，常见的可以被同位语从句修饰的名词有：belief,chance,doubt,hope,idea,news,opinion,thought,promise 等。
引导同位语从句的词有连词that,whether 和副词how,when,where 等。
二、同位语从句点拨（1）同位语从句是意义完整的陈述句时，用连词that 引导。
注：that 在从句中不充当任何成分，只起连接作用，通常不省略。
如如：I got the news that he would come to see methe next week.（2）同位语从句是疑问句时，应根据语境选用who,when ,where,how,whether（不能用if）等词来引导。
如：The question who is the best for the job requires consideration.（3）分隔式同位语从句：当主句的谓语较短，而同位语从句较长时，为了使句子保持平衡，常把同位语从句后置。
如：An idea came to him that he could buy her a diamond ring.（4）后面常跟同位语的词有：doubt,fact,hope,idea,message,news,possibility,promise,question,suggestion,truth,thought,warning,wish 等。
注：advice,order,suggestion 等词表示建议、命令的词后的同位语从句中的谓语动词须用（should） + 动词原形。
如：He madethe suggestion that the meeting（should） be put off.三、同位语从句与定语从句的区别（1）所表达的内容不同：同位语从句和定语从句一般是放在某一名词后面，但同位语从句是对该名词的解释和说明，而定语从句是对该名词的修饰，说明它的性质特征。
如：The factthat he presented was a strong proof.他所提供的事实是一个强有力的证据。
（定语从句）The fact that she hadn 'tsaid anything surprised us all.她一言不发的事实让我们每一个人都很惊讶。
（同位语从句）（2）在句中所起的语法作用不同：引导定语从句的that 是关系代词，它的作用是连接主句和从句，并代表先行词在从句中充当句子成分，而且that 作宾语时可省略，指物时，可以用which 代替。
引导同位语从句的that 是连词，只起连接主句和从句的作用，它不充当任何成分，不能省略，也不可被which 代替。
如:We expressed the hope that Mr and Mrs Smith would come to visit China the next year.我们表达了希望史密斯夫妇第二年到中国来访的愿望。
（同位语从句）The news（that/which）we heard spread all over the city.我们所听到的消息传遍了整个城市。
（定语从句）（3）所修饰的词不尽相同：同位语从句所修饰的名词数量有限，往往是含有某种信息的词，如：message,news,fact,hope,desire,problem,idea,suggestion,advice,questtionorder,belief,doubt,fear,truth,throught 等，而定语从句修饰的先行词无此限 制。
(4) wh-引导词引导同位语从句时， 有其本身的疑问含义；引导定语从句时则没有疑问的意思。
如；I have no idea where the meeting will be held.(同位语从句) He is the only one of these boys who can speak Franch. (定语从句)四、 相关练习(1)There is no obvious evidence _______ there is life on any other planet in thesolar system.A.whichB.thatC.howD.where解析：选B 没有确凿的证据证明太阳系的其他行星上有生命。
Evidenee 后的同位语 从句不缺少任何成分，故用 that 引导。
(2) My friend showed me round the town, ___ was very kind of him.A.whiehB.thatC.whereD.it解析：选 A 我的朋友领我参观了这个城镇，他真好。
非限制性定语从句缺少主语， 所以用 whieh 引导，先行词是前面的整个句子。
That 不能引导非限制性定语从句； where 引导定语从句在从句中作状语； it 不能引导从句。
(3) Many ehildren, ___ parents are away working in big eities,are taken goodeare of in the village.A.theirB.whoseC.of themD.with whom解析：选B 许多孩子的父母远在大城市打工， 这些孩子在乡村都得到了很好的照顾。
根据句子结构判断，逗号后面是定语从句，从句主语 parents 前缺少定语，故用关 系代词whose 引导。
Their 和of them 不能引导定语从句；with whom 不能作定语。
(4) It 's helpful to put ehildren in a situation differently. (5) _______________________________________________________ Many young people in the West are expeeted to leave ______________________________ eould be life 's most important deeision—marriage---almost entirely up to luek.A.asB.thatC.whiehD.what解析： 选 D 许多西方年轻人可能会把自己一生最重要的决定 --------- 婚姻，几乎完 全寄托于运气。
Leave 在此是及物动词，表示“把……留给某人决定” ，所选项引导 其宾语从句并在从句中作主语， 所以选连接代词 what 。
As 不引导名词性从句；that引导名词性从句不作成分； whieh 表示选择意义，意为“哪一个” 。
