3同位语从句学习指导及练习

1、 同位语从句误区探秘同位语从句是对与之同位的名词中心词作进一步解释，说明该名词的具体内容，一般由that引导。能接同位语从句的常见名词有：idea, fact, news, belief, hope, evidence, opinion, problem, truth, answer, proposal, theory, decision, discovery, thought等。误区一 引导同位语从句的that 可以省略that引导同位语从句时，仅起连词作用，没有实际意义，也不在从句中作任何成分，且表示肯定或明确意义，但不能省略。例1 Some researchers believe tha

2、t there is no doubt _ a cure for AIDS will be found.(05广东） A. which B. that C. what D. whether【解题指导】在doubt, possibility, order, news, word, idea, hope, suggestion, information, plan, thought, fear, belief等名词后，说明其具体内容的从句是同位语从句，从句中不缺句子成分，意义非常完整，用that引导。故答案是B。例2 Danby left word with my secretary _ he w

3、ould call again in the afternoon.(05浙江) A. who B. that C. as D. which【解题指导】从句子的结构和意义两方面分析可知，空格后的从句说明的是word的具体内容，表达了明确的意义，因此应选用that引导同位语从句。同位语从句“that he would”与它所说明的名词word被with my secretary分开了。Word这里是不可数名词，意思为“话、口信”。误区二 同位语从句只能用that引导同位语从句除了用连接词that引导外，根据其结构和意义，也可以由whether, 连接代词who, what, whose, whic

4、h，连接副词how, when, where, why，how等引导。在doubt, question, fear等表示“怀疑，疑问”等意义的抽象名词后的同位语从句通常用whether引导，且表示不肯定或不明确，即含“是否”之意，此时从句也不缺句子成分。例3 The question _ it is right or wrong depends on situation. A. whether B. that C. what D. when 【解题指导】根据句意“是非正误还是问题”解释说明question的内容，但又表明了不肯定的意义，因此此题应选whether,表示“是否”。 当idea作名

5、词用于肯定句后面跟同位语从句时，根据句意以及句子结构，可以用连接代词who, what, whose, which，连接副词how, when, where, why等引导同位语从句，且在从句中要充当一定的句子成分。例4 Do you have any idea _ is actually going on in the classroom?(05辽宁) A. that B. what C. as D. which【解题指导】 根据所给信息判断，as, which不能引导同位语从句，再根据句子结构判断，从句中缺少主语，故应选what引导同位语从句。实际上这里是省去了介词of的用法。误区三 同位

6、语从句与定语从句混用同位语从句是说明名词中心词（往往是一些表事实或概念的抽象名词）的具体内容，that引导同位语从句时，起连词作用，没有实际意义，也不作句子的任何成分，一般不能省略；而定语从句是对先行词加以修饰、限制，描述先行词的性质、特征，that在定语从句中充当一定的句子成分，为关系代词，作宾语时，that可以省略。例5 Theres a feeling in me _ well never know what a UFO is not ever.(02上海) A. that B. which C. of which D. what 【解题指导】根据句意判断，从句well never kn

7、ow what a UFO is not ever作a feeling的同位语。解释其具体内容，故选答案that。that只起连接作用，不作从句的任何成分。 例6 We dont believe the news _ he told us yesterday. A. that B. what C. when D. how 【解题指导】根据句子结构判断，从句中谓语动词told带直接宾语，故应判断为定语从句，选答案that，在定语从句中作宾语。能用which吗？可以省去吗？为什么？The thought came to him _ he had no time to prepare for the
