当主句的谓语动词是think, believe, guess, expect, imagine, suppose等时，如果宾语从句是否定结构，通常把主句谓语动词改为否定式，而将宾语从句改为肯定式，这种现象叫做否定转移。 I dont think we two have met before. We dont believe that he could finish his work in such a short time. She doesnt think it is right for John to come late to school. 三、表语从句 ：通常置于主句的系动词之后，说明主句主语的情况。 My idea is that we should help her do housework every Sunday. Is that why you had a few days off? It is because I have never heard of the story. 四、同位语从句 ：常置于某些名词之后，对其内容作解释或补充说明。如: advice, demand, doubt, fact, hope, idea, news, order, problem, promise, question, request, suggestion, truth, wish, word等。 The news that we won the game is exciting. There is no doubt that he is the best player in their country. 同位语从句与定语从句的区别： 同位语从句对所修饰词作补充说明，而定语从句对前面名词起限定作用; that在同位语从句中只起引导作用，无词义，无语法成分，而在定语从句中指代所修饰词并在从句中作主语或宾语。 |
