1、同位语从句学习指要当名词后面所接的从句表示与名词同位并为名词的实际内容时,这个从句就是同位语从句。如:The news that China has joined the WTO excite us all. 中国加入了世界贸易组织这一消息使我们大家兴奋不已。He told us the truth that he fell down from his bike this afternoon. 他告诉了我们他从单车上摔下来这一真相。同位语中应注意:1.高中所学能带同位语从句的名词不多,常见的有:answer, belief, conclusion, decision, discovery, d
2、oubt, explanation, fact, hope, idea, information, knowledge, law, message, news, opinion, order, possibility, problem, promise, proof, proposal, question, report, risk, rumor, story, suggestion, truth, theory, thought, wish, word等。如:He sent us a message that he wont come next week. 他送信来告诉我们说,下周他不来了。
3、There is no doubt that he is fit for this job. 毫无疑问,它适合这一工作。2.表示“命令、建议、要求” advice, demand, decision, desire, idea, insistence, instruction, order, plan, proposal, recommendation, request, requirement, suggestion, wish 等名词的同位语,须用虚拟语气。如:He made clear his desire that he should work hard to go to colleg
4、e. 他已清楚的表明了他要努力学习考上大学这一愿望。Soon came the order that all the people should obey the rules. 不久命令下来了,所有的人不得违犯制度。3.同位语从句与定语从句的区别:同位语从句与定语从句形相似而实质不同,具体表现在以下几个方面:(1)被修饰的词不同。同位语从句的前面一般是数量有限的、表示抽象意义的名词;而定语从句的先行词是无数的指人或物名词。(2)从句的作用不同。同位语从句表示同位名词的具体内容;而定语从句是对先行词名词的限制、描绘或说明。(3)引导词的作用不同。引导同位语从句的that是连词,在从句中不担任任何成分,但不能省略;而引导定语从句的that为关系代词,在从句中担任句子的某种成分,当担任定语从句中的宾语时,that可以省略。(4)引导词不同。定语从句不能用what, how, whether引导;而同位从句可以用what,how, whether引导。(5)判定定语从句和同位语从句的方法。同位语从句可充当同位名词的表语;而定语从句不能充当先行词的表语。
