同位语从句练习题

同位语从句练习题

同位语从句在句中起同位语的作用。它一般跟在某些抽象名词（如fact, news, idea, promise等）的后面，用以说明或解释前面的名词。
引导同位语从句的连词多用that。that在同位语从句中只起连接作用，不充当任何成分，但不可省略。
① The fact that the earth is becoming warmer and warmer is clear.
② The news that our team won the football game inspired all the fans.
③ They introduced the idea that children could learn to read as babies.
④ Tom made his teacher a promise that he would never be late again.
少数情况下同位语从句也可用连词whether和连接代词who，what，which或连接副词when，where，why，how等引导。
① I have no idea whether it is safe to sail in this weather.
② Have you got any idea who will take over now that the president has resigned?
③ Here comes the question what we should do with so much e-waste.
④ I have no idea when the general manger will come back.

例1：i have no idea when he will be back.

　　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。

　　例2：i have no impression how he went home，perhaps by bike.

　　析：he went home意义不完整，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。

　　例3：information has been put forward ____ more middle school graduates will be admitted into universities.（nmet2001上海）

　　a.while b.that c.when d.as

　　析：答案为b.more middle school graduates will be admitted into universities是information的内容，且information不在从句中作成分，所以该句为同位语从句。应将该句区别于：

　　it is said that more middle school graduates will be admitted into universities，this is the information ____ has been put forward.

　　a.what b.that c.when d.as

　　析：答案为b.that has been put forward为information的修饰性定语，且information在从句中作主语，所以该句为定语从句。

　　例4：she heard a terrible noise，____ brought her heart into her mouth.（met91）

　　a.it b.which c.this d.that

　　析：答案为b.分析语境含义、句子结构和句子成分可知，该句为非限制性定语从句，先行词为a terrible noise，且它在从句中作主语。应将该句区别于：

　　i can’t stand the terrible noise ____ she is crying loudly.

　　a.it b.which c.this d.that

　　析：答案为d.she is crying loudly是the terrible noise的内容，且the terrible noise不在从句中作成分，所以该句为同位语从句。
