第11讲 名词性从句的5个高频考点与2种解题方法 备考指导 名词性从句是历年高考中考查的最多的一个考点,通常是以单项填空、语法填空、短文改错和书面表达的形 一、名词性从句中的5个高频知识点 1.只能用whether不能用if的4种情况 (1)引导主语从句且位于句首 (2)引导表语从句 (3)从句为介词的宾语 (4)后紧跟不定式 2.有些动词带宾语从句时需要在从句前加it 如:hate,like,take,owe,have,see to,depend on,rely on等,除此之外, take it for granted中的it是位于动词而不是从句之前。 I hate it when people talk with their mouths full of food.我讨厌他们满嘴食物时说话。 3.不能省略that的宾语从句 (1)it作形式主语时 (2)宾语从句较长时 (3)主句的状语置于主句句尾、宾语从句之前 I realized at once that I had dialed the wrong number. 我立即认识到了我打的号码错了。 (4)宾语从句中的状语或状语从句置于从句句首时 He told us that if we would all come to help out the whole situation would be looking up.他告诉我们如果我们能够全部来帮忙整个局势会好转。 (5)主句谓语动词(包括非谓语动词)与宾语从句之间有插入语时 He found,however,that this was not true. 然而,他发现这不是真的。 (6)一个动词有两个宾语从句,第一个可以省略,但是第二个不能省略 4.主语为名词reason时,表语从句的引导词用that不能用why 5.如果指人的引导词具有双重身份,则用whoever 也就是说引导词既是从句的主语也是主句的主语,这时候应该用whoever,因为whoever相当于anyone who,he who等。 Whoever doesn’t reach the Great Wall is not a true man. 不到长城非好汉。(whoever既是主句的主语也是从句的主语) I will give the prize to whoever comes out first. 谁是第一我就把奖给谁。(whoever既是to的宾语,还是从句的主语)二、2种方法帮助你解决名词性从句的相关题目 方法1 位置判断法 根据名词性从句的句子特点及其所处的位置,判断出属于哪一种从句,从而确定连词的种类,也有助于对句子的理解。 What he said astonished us.他所说的话使我们很惊奇。(从句在主语位置,为主语从句) Everything depends on whether you have enough money.一切都看你是否有足够多的钱。(从句在介词后,为介词的宾语,为宾语从句) The question is where we’ll go this Sunday.问题是我is后,为表语从句) He expressed the hope that he would come to China again.他表达了再来中国的愿望。(从句在抽象名词后,对名词解释说明,为同位语从句) 典例展示1 (2015·全国卷)After looking at the toy for some time, he turned around and found where his parents were missing.________ 答案 where→that或去掉where 解析 found后为宾语从句,引导词不作句子成分只起连接作用,应用that引导,而且that可省略。故where改为that或去掉where。 典例展示2 (2014·四川高考)If you notice that when someone is missing or hurt, tell your teacher immediately.________ 答案 去掉when 解析 notice之后为that引导的宾语从句,when属于多余词。故去掉when。 典例展示3 It is still under discussion ________ the old bus station should be replaced with a modern hotel or not. 答案 whether 解析 句意:那个旧公交车站是否应该被一家现代化It”作形式主语, “________ the old bus station should be
