高考英语一轮复习——名词性从句（附答案） I. 考点分析 名词性从句包括：主语从句、宾语从句、表语从句、同位语从句，多由连词that ，wh- 疑问词或 由what ，whatever 等关系代词引导，其中同位语从句在高考考试中最常见。 1. 主语从句 1) 主语从句在句子中充当主语，句子的谓语动词用第三人称单数。如： Why he refused to work with you is still mystery. Whoever comes is welcome. 2) 主语从句前的that 不能省略，仅起连接作用，有时为了保持句子平衡，that 从句后置，而由it 作 形式主语。如： That he became a lawyer may have been due to his mother’s influence. It is not true that he has moved to New York. 2. 宾语从句在句子中充当宾语，如： I don’t know where the sound came from. Don’t be satisfied with what you have achieved. 3 ．当从句放在系动词 be, look, remain, seem 等后即构成表语从句。 The trouble is that I have lost his address. It seemed that the night would never end. 4. 1) 同位语从句是对与之同位的名词中心词作进一步解释，能接名词性从句的常见名词有: idea, fact, news, belief, hope, evidence, opinion, problem, truth, answer, proposal, theory, decision, discovery, problem, thought, understanding 等。 The news that he has passed the examination is exciting. 2) 同位语从句与定语从句的区别在于：定语从句是对先行词加以修饰、限制，而同位语从句时说明 名词中心词的具体内容；that 在定语从句中充当成分，为关系代词，而在同位语从句中不做任何成分, 仅起连词作用。如： The fact that we talked about is very important. (定语从句) The fact that he succeeded in the experiment pleased everybody.( 同位语从句) 5. whether 与if 在名词性从句中的用法区别 if 一般只用于引导宾语从句，而 whether 可引导包括宾语从句在内的其他名词从句。 1) 连词whether 引导的主语从句，表语从句不能用if 来替换。 Whether he will attend the meeting is uncertain. The question is whether he will come. 2) 宾语从句中，whether 常与or not 搭配，可以说whether or not，而不说if or not 。 I don’t care whether or not she will attend the meeting. 3) whether 可用在介词后，或带to 不定式前，if 则不可。 She doesn’t know whether to get married now or wait. I haven’t settled the question of whether I’ll go back home. 4 ）某些动词后面( discuss)只能用whether ，不用if 。 We discussed whether we should go on climbing.
