Step3 單元語法
複習同位語
1
概念
同位語是句子成分的一種，位於名詞、代詞後面，說明它們的性質和情況，它可以由名詞、代詞、名詞性短語或從句充當。
The program is attractive. The program is WhereAre We Going, Dad.
→The program, Where Are We Going, Dad, is attractive.
同位語的表現形式
同位語除可以直接位於所修飾的名詞、代詞後外，也可以用“suchas, that is, of, or”等詞引導。
The freezing temperature is the temperature at which water freezes under ordinary pressure. Freezing point is that too.
→The freezing temperature, or freezing point,is the temperature at which water freezes under ordinary pressure.
2
同位語從句
概念：一個句子在複合句中起到同位語的作用，對前面的名詞進行解釋說明。這個句子被稱為同位語從句。
He told me the news—he would come home from abroad soon.
→He told me the news
that he would come home from abroad soon.3
用法：同位語從句一般位於“fact,news, idea, truth, hope, belief, thought, doubt, question, promise,information”等抽象名詞後，解釋前面名詞的具體含義。
When will he come back? I have no idea.
→I've no idea when he will come back.
4
同位語從句連接詞有“that,whether, who, which, what, when, where, why, how”等。
Should we continue to do the experiment？The problem has not been solved.
→The problem whether we should continue to do the experiment has not been solved.
5
同位語從句與定語從句的區分：同位語從句所修飾的名詞在從句中不作成分；定語從句所修飾的名詞在從句中充當句子成分。
①Thenhe raised the question.
Wherewere they to get the machine needed?
→Thenhe raised the question where they wereto get the machine needed.(同位語從句)
②Doyou know the place? He was born in the place.
→Doyou know the place where he was born？(定語從句)
