36、的才干的。（but = who dont）同位语从句详细讲解一、定义及相关术语同位语：一个名词或代词后面有时跟一个名词或起名词作用的成分，对前者进一步说明。同位语从句一般用来解释或说明前面名词的具体含义或内容，在逻辑上表现为同位关系。同位语从句的引导词有：关系代词（that,，whether，what，which，who），关系副词（when，where，why， how ），通常由 that 引导。常用于同位语从句的名词有：advice（建议），demand（要求），information（信息），news（信息），order（命令），promise（答应），request（要求），sugg

39、。例：The news that they had won the game soonspread over the whole school他.们比赛获胜的消息很快传遍了整个学校。精品资料_二、同位语从句的引导词使用情况1.如同位语从句意义完整，应用 that 引导同位语从句。（即 that 不充当任何成分，只起连接作用，不可省略）The general gave the order that the soldiers should cross the river at once将.军下达了战士们立即过河的命令。解析:the soldiers should cross the river a

40、t once是the order的全部内容，且意义完整，因此应用that 引导同位语从句。2.如同位语从句意义不完整，需增加"是否"的含义，应用whether 引导同位语从句。（if不能引导同位语从句）We'll discuss the problemwhether the sports meeting will be held on time我.们将讨论运动会是否会如期举行的问题。解析：the sports meeting will be held on time意义不完整，应加"是否"的含义才能表达 the problem的全部内容，因此应用

41、whether 引导同位语从句。3.如同位语从句意义不完整，需增加"什么时候"、"什么地点"、"什么方式"等含义，应用 when, where, how等词引导同位语从句。I have no idea when he will be back.解析：he will be back 意义不完整，应加"什么时候"的含义才能表达idea 的全部内容，因此应用when 引导同位语从句。I have no impressionhow he went home, perhaps by bike.解析：he went home意

42、义不完整，应加"如何"的含义才能表达impression的全部内容，因此应用how 引导同位语从句。4.当主句的谓语较短，而同位语从句较长时，同位语从句可以和同位的名词分开。同位语从句常后置。The thought came to him that maybe the enemy had fled（逃跑）the city.The story goes that he beats his wife. 传说他打老婆。The news got about that he had won a car in the lottery. 消息传开说他中彩得了一辆汽车。三、同位语从句的语气

43、在 suggestion, advice, request, order等意为“建议；命令；要求”的名词后，同位语从句中的谓语动词通常用“should +动词原形”的虚拟语气结构，句中的should 可以省略。精品资料_例如：Our teacher gave us some advice how we (should) use the computer.老师给我们提出了一些如何使用电脑的建议。The suggestion came from the chairmanthat the new rule (should) be adopted.采纳新规则的建议是主席提出来的。The governm

44、ent gave the order that all these houses (should) be pulled down in three weeks.政府下令三个星期内所有这些房子都要拆掉。定语从句与同位语从句的区别一、意义的不同同位语从句是用于说明所修饰名词的具体内容的，它与先行词是同位关系；而定语从句是限制所修饰名词的，它与先行词是修饰关系。We are glad at thenews that he will come. 听到他要来这个消息我们很高兴。(news的内容就是that he will come，故 that 引导的是同位语从句)We are glad at then

45、ewsthat he told us. 听到他告诉我们的这个消息我们很高兴(that。从句是限制the news 的内容的，即我们高兴只是因为他告诉的这个news 而不是其他的news，故 that 从句为定语从句)二、引导词的不同what, how, if, whatever等可引导同位语从句，但不引导定语从句。定语从句由关系代词或关系副词引导，关系词在从句中担当相应的句子成分，关系代词在从句中作宾语时经常可省略。同位语从句主要由连词that 引导，在从句中一般不担当成分；有时也由where,when, how,who, whether, what 等连词引导，这些连词则在从句中担当成分。T

46、he news that he told me is true. （定）他告诉我的消息是真的。The news that he has just died is true. （同）他刚刚去世了，这个消息是真的。 The problemthat weare facing now is how we can collectso much money. (定) 我们现在面临的问题是如何筹集这么多资金。The problemhow we can collectso muchmoney is difficultto solve. （同） 我们如何筹集这么多资金，这个问题很难解决。精品资料_三、被修饰词语

47、的区别同位语从句所修饰的名词比较有限，通常有 hope, wish, idea, news, fact, promise, opinion, suggestion, truth等，而定语从句所修饰的名词则非常广泛。 另外，when 和where 引导定语从句时，通常只修饰表示时间和地点的名词，而它们引导同位语从句时却不一定；又如 why 引导定语从句，它通常只修饰名词the reason，而它引导同位语从句时则不一定。I have no idea when they will come . 我不知道他们什么时候来。(同)Illnever forget the days when I lived

48、 there. 我永远不会忘记我住在那儿的日子。(定)We dontunderstand the problem why this is the best choice. 我们不明白这个问题，为什么这是最好的选择。(同)The reasonwhy he didntcome to the meeting is that he is ill.他未能来开会，原因是他生病了。(定)四、是否可以发展成完整句子同位语从句与先行词一般可以用动词 be 发展成一个完整的句子, 而定语从句则不能。A. The idea that we could ask the teacherfor advice is won
