,英语课件：人教版必修三Unit5Section,语法专题突破,同位语从句,一、定义,同位语从句就是跟在某一名词后，进一步说明该名词具体内容的从句。,同位语从句一般跟在某些抽象名词的后面，用于解释或说明前面名词的内容。可带同位语从句的抽象名词有：,news,，,answer,，,message,，,doubt,，,possibility,，,idea,，,reply,，,reason,，,belief,，,hope,，,promise,，,suggestion,，,question,，,certainty,等。,英语课件：人教版必修三Unit5Section,二、连接词,可引导同位语从句的有从属连词,that,，,whether,；连接代词,who,，,which,，,what,；连接副词,when,，,where,，,why,，,how,等。,1,连词,that,和,whether,引导的同位语从句。该类引导词只起连接作用，在从句中不作任何成分。,There is no doubt that prices of cars will go down.,毫无疑问，轿车的价格会下降。,英语课件：人教版必修三Unit5Section,2,连接代词和连接副词引导的同位语从句。该类引导词在从句中作相应的成分。,Next comes the question what you want to put in the box.,其次就是这个问题：你想在盒子里放些什么。,Nobody can explain the mystery why he suddenly disappeared.,没人能解开为什么他突然消失了这个谜。,英语课件：人教版必修三Unit5Section,三、学习同位语从句应注意的要点,1,表达,“,是否,”,的概念时，要用,whether,而不用,if,引导同位语从句。,I have no idea whether you are interested in working for her.,我不知道你是否有兴趣为她工作。,2,分隔式同位语从句：有时同位语从句与其先行词被其他成分隔开，这种分隔主要出于修辞原因，即为了保持句子结构平衡。,英语课件：人教版必修三Unit5Section,His promise was along with the letter that he would visit me this coming Christmas.,信中他承诺在即将到来的圣诞节他会来拜访我。,3,在某些抽象名词后的同位语从句中，其谓语动词应用虚拟语气形式，即,(should,),动词原形。常见的这类名词有：,advice,，,order,，,demand,，,plan,，,proposal,，,suggestion,，,request,，,requirement,，,decision,，,recommendation,等。,The suggestion that a new bridge (should) be built was accepted.,修建一座新桥的建议被采纳了。,英语课件：人教版必修三Unit5Section,4,名词,doubt(,怀疑,),后的同位语从句用,whether,引导；,no doubt(,不怀疑,),之后的同位语从句用,that,引导。,We have some doubt whether they can complete the task on time.,我们怀疑他们能否按时完成任务。,There is no doubt that he will keep his promise.,他将遵守他的诺言，这一点是毫无疑问的。,英语课件：人教版必修三Unit5Section,四、同位语从句与定语从句的区别,1,同位语从句属于名词性从句，它对先行词作进一步的解释或补充说明；而定语从句则属于形容词性从句，它对先行词起修饰或限制的作用。,The foreigner expressed the hope that he would come to China again.(,同位语从句,),Ill remember the hope that the foreigner expressed to me.(,定语从句,),英语课件：人教版必修三Unit5Section,2,同位语从句的先行词通常是抽象名词；而定语从句的先行词无此限制。,The possibility that socialists clone a man may come true.(,同位语从句,),This is the horse that the scientist cloned.(,定语从句,),3,引导同位语从句的,that,只起连接作用，往往没有任何意思，在句中也不作成分，通常不被省略；而,that,引导定语从句时为关系代词，它除了起连接作用外，在从句中还充当某一成分,(,如主语、宾语等,),，作宾语时可以省略。,英语课件：人教版必修三Unit5Section,He made a promise that if anyone set him free he would make him very rich.(,同位语从句,),I still remember the promise (that) he made.(,定语从句,),4,当,when,，,why,，,where,和,how,等引导同位语从句时，它们为连接副词，虽然在句中充当句子成分，但前面没有与其意义相当的先行词；而在定语从句中它们为关系副词，在其前面分别有表示时间、原因、地点或方式意义的名词作先行词。,Then arose the question where we were to get so many chairs needed.(,同位语从句,),Thats the reason why he didnt come to the meeting.(,定语从句,),英语课件：人教版必修三Unit5Section,.,完成句子,1,(2011,年高考天津卷改编,) Modern science has given clear evidence _ (,吸烟能导致很多疾病,),答案：,that smoking
