基礎班語法同位語和同位語從句

1、基礎班語法同位語和同位語從句同位語：一個名詞(或其它形式)對另一個名詞或代詞進行修飾，限定或說明，這個名詞(或其它形式)就是同位語。同位語與被它限定的詞的格要一致，并常常緊挨在一起。 1.由兩個或兩個以上同一層次的語言單位組成的結構,其中前項與后項所指相同,句法功能也相同,后項是前項的同位語。 Mr. Smith, our new teacher, is very kind to us. Yesterday I met Tom, a friend of my brother's. 2.如同位語與其同位成分關系緊密時不用逗點隔開;如同位語對其同位成分只作補充解釋時可用逗點隔開。 He h

2、imself told me that his brother John is a world-famous doctor. Yesterday I talked to my English teacher, Mr. James. 3.同位語除表示其同位成分的全部意義外,還可以表示部分意義。 We Chinese people are brave and hardworking. He is interested in sports, especially ball games. 在復合句中充當同位語的名詞性從句稱為同位語從句。同位語從句是名詞性從句（主語從句、表語從句、賓語從句、同位語從句）

3、中的主要從句之一，也是中學英語學習中的重點語法知識點之一。在使用同位語從句時，應注意以下五個方面：一、同位語從句在句中的位置1. 一般情況下同位語從句跟在某些名詞（如news，idea，fact，promise，hope，message等）的后面，用以說明該名詞所表達的具體內容。例如：The news _ encouraged us all greatly. 我們女排贏得冠軍的消息大大地鼓舞了我們所有人。2. 有時同位語從句可以不緊跟在它所說明的名詞后，而被別的詞語隔開，在語法上叫做分隔式同位語從句。例如：The thought came to her_. 她突然想起可能在她離開家時沒把門關上

4、。The story goes _. 據(jù)說他高考又落榜了。二、同位語從句前名詞的數(shù)同位語從句前的名詞通常用單數(shù)形式，并且往往帶有限定詞（word除外）加以修飾。例如：Where did you get the idea that I could not come？ 你在哪兒聽說我不能來？三、同位語從句連接詞的選用1.同位語從句：that有些名詞的后面可以接that(不用which)引導的同位語從句. 如果同位語從句意義完整,不缺少句子成分,常用that引導同位語從句advice，announcement，argument，belief，claim，conclusion，decision，evi

5、dence，explanation，fact，feeling，hope，idea，impression，information，knowledge，message，news，opinion，order，probability，promise，proposal，remark，reply，report，saying，statement，suggestion，thought，treat，warning，wish，word I've come from Mr Wang with a message _.我從王先生那邊得知一個消息，他說他今天下午不能來看你了。Word came_. 消息傳來，中

6、國于2003年10月15日首次成功發(fā)射了載人飛船。Give me your promise_. 答應我，你今天晚上要來參加我們的晚會。2. 同位語從句：whether 如果同位語從句表示"是否"含義時,常用whether (不用if)引導同位語從句。例如: He must answer the question _.他必須回答他是否同意這樣一個問題。 whether可以引導同位語從句，而定語從句不能用whether作為引導詞。He hasn't made the decision_. 他還沒有做出決定是否去那里。I have small doubt_. 他是否適合這

7、件工作我有點懷疑。3. 同位語從句：what 可以引導同位語從句，而定語從句不能用what作為引導詞I have no idea_. 我不知道他現(xiàn)在在干什么。4.同位語從句：how 可以引導同位語從句，而定語從句不能用how作為引導詞It's a question_. 那是一個他如何做了此事的問題。5. 同位語從句：who，whom，which，when，where，why用來引導同位語從句The question _requires consideration. 誰該干這項工作，這個問題需要考慮。She raised the question_. 她提出這個問題：我們到哪兒去搞這筆資

8、金。四、同位語從句的語氣。在suggestion，advice，request，order等意為“建議；命令；要求”的名詞后，同位語從句中的謂語動詞通常用“should +動詞原形”的虛擬語氣結構，句中的should可以省略。例如：Our teacher gave us some advice_.老師給我們提出了一些如何使用電腦的建議。The government gave the order_. 政府下令三個星期內所有這些房子都要拆掉。五、同位語從句與定語從句的用法區(qū)別區(qū)別（1）同位語從句和先行詞是同等的關系，而定語從句是用來修飾先行詞，是從屬的關系。區(qū)別（2）that在同位語從句中沒有詞義

9、，不充當句子成分；而在定語從句中充當主語、賓語等句子成分。The news that you heard is not true. (_從句)The news that he has died is true. (_從句)The fact that just now you talked about interests me. (_從句)The fact that he failed in the exam made his parents very angry. (_從句)區(qū)別（3）whether，what，how可以用來引導同位語從句；而它們不能用來引導定語從句。We have no in

10、formation whether he is alive. The problem whether it is right or wrong has not been decided yet. Next comes the question what step we should take.區(qū)別（4）1. 從詞義角度看問題who，whom，which，when，where，why用來引導同位語從句是保持原來疑問詞的含義；它們用來引導定語從句時，不具有疑問詞的含義。He didn't give the answer why he was late. (_從句) This is the

11、house where he saw the thief. (_從句)Then rose a question where we should go. (_從句)The man who broke into the house last night was caught. (_從句)2. 從搭配角度看問題who，whom，which，when，where，why用來引導定語從句時對應性很強，如：先行詞是“人”，引導詞用“who”等，而它們引導同位語從句是先行詞通常是“question，idea，doubt等”。I still remember the day when he was kille
