1、高中英語語法專題講解專題二、同位語從句一、同位語從句概述 同位語從句是用以解釋說明某一名詞內容的從句，常見的可以被同位語從句修飾的名詞有：belief, chance, doubt, hope, idea, news, opinion, thought, promise等。引導同位語從句的詞有連詞that, whether和副詞how, when, where等。二、 同位語從句（1） 同位語從句是意義完整的陳述句時，用連詞that引導。注：that在從句中不充當任何成分，只起連接作用，通常不省略。eg：I got the news that he would come to see me t

2、he next week.（2） 同位語從句是疑問句時，應根據語境選用who, when ,where, how, whether(不能用if)等詞來引導。eg：The question who is the best for the job requires consideration.（3） 分隔式同位語從句：當主句的謂語較短，而同位語從句較長時，為了使句子保持平衡，常把同位語從句后置。eg：An idea came to him that he could buy her a diamond ring.（4） 后面常跟同位語的詞有：doubt, fact, hope, idea, mes

3、sage, news, possibility, promise, question, suggestion,truth,thought,warning,wish等。 注：advice, order, suggestion等詞表示建議、命令的詞后的同位語從句中的謂語動詞須用(should) +動詞原形 eg：He made the suggestion that the meeting(should) be put off.三、 同位語從句與定語從句的區別（1） 所表達的內容不同：同位語從句和定語從句一般是放在某一名詞后面，但同位語從句是對該名詞的解釋和說明，而定語從句是對該名詞的修飾，說明它

4、的性質特征。eg：The fact that he presented was a strong proof. The fact that she hadnt said anything surprised us all. （2） 在句中所起的語法作用不同：引導定語從句的that是關系代詞，它的作用是連接主句和從句，并代表先行詞在從句中充當句子成分，而且that作賓語時可省略，指物時，可以用which代替。引導同位語從句的that是連詞，只起連接主句和從句的作用，它不充當任何成分，不能省略，也不可被which代替eg：We expressed the hope that Mr and Mrs

5、Smith would come to visit China the next year. The news that we heard spread all over the city.（3） 所修飾的詞不盡相同：同位語從句所修飾的名詞數量有限，往往是含有某種信息的詞，如：message,news,fact,hope,desire,problem,idea,suggestion,advice,questtion,order, belief, doubt, fear, truth, throught等，而定語從句修飾的先行詞無此限制。 （4） wh-引導詞引導同位語從句時，有其本身的疑問含義

6、；引導定語從句時則沒有疑問的意思。eg：I have no idea where the meeting will be held.He is the only one of these boys who can speak Franch. 跟蹤練習：1、There is no obvious evidence_ there is life on any other planet in the solar system.A. which B. that C. how D. where2、My friend showed me round the town, _was very kind of
