2016届高考英语二轮语法专项复习课件：专题9 名词性从句（新人教版）

　　一 二 一、选择合适的连接词 名词性从句就是具有名词作用的从句。它在句中可以作主语、宾语、表语和同位语。解决有关名词性从句的问题的关键是:通过从句的位置,辨别从句的类型;分析从句,看看从句中所缺少的句子成分和句意,最终确定选用合适的连接词。 通过下面几个句子,看看从句的类型: 1.That our team had won the match made us excited.(位于谓语之前,主语从句)  2.The headmaster said that our team had won the match.(位于谓语之后,宾语从句)  3.The fact was that our team had won the match.(位于系动词之后,表语从句)  4.The headmaster announced the news that our team had won the match.(位于名词之后,同位语从句)  一 二 一 二 一 二 一 二 一 二 二、名词性从句的几个特殊情况 1.it用作形式主语的常见句型为: (1)It +be +形容词(obvious,true,natural,surprising,good,wonderful,possible,likely,certain,probable,etc.)+ that... (2)It + be +名词词组(no wonder,an honour,a good thing,a pity,no surprise,etc.) + that... (3)It +be +过去分词(said,reported,thought,expected,decided,announced,suggested,etc.) + that... (4)It + seems/appears/happens 等不及物动词及短语+ that... (5)It doesn’t matter ( makes no differences,etc.) + 连接代词或连接副词引导的主语从句 一 二 It makes no difference where we shall have the meeting. It is a pity (that) we haven’t contacted for ages. 很遗憾,我们几年没联系了。 It has not been decided where the meeting is to be held. 在哪里开会还没决定。 It doesn’t matter whether she will come or not. 她是否来这无关紧要。 一 二 2.it用作形式宾语 如果宾语从句后还有宾语补足语,则必须用it作形式宾语,而将宾语从句后置,并且that不能省略。句型结构为: (1)make/find/feel/consider/think it+ adj./n.(宾语补足语)+that... (2)like/dislike/love/hate/appreciate+it+if/when... I think it best that you should stay here. 我认为你最好住这儿。 He hasn’t made it known when he is going to get married. 他还没宣布他何时结婚。 I hate it when people laugh at the disabled. 我讨厌别人嘲笑我的残疾。 一 二 3.动词 doubt后接宾语从句时,通常要用 whether (if) 来引导,而不用 that,因为 doubt 表示“怀疑”,其意不肯定、不明确;但是如果它用于否定式,其后的宾语从句则通常用 that 来引导,因为 not doubt 表示“不怀疑”,其意是肯定的、明确的。 I doubt if/whether he’ll come. 我拿不准他是否会来。 I don’t doubt that he will succeed. 我敢肯定他会成功。 Do you doubt that he will win? 你不相信他会赢吗? 一 二 4.be sure后的名词性从句通常用that引导,而 be not sure 后的名词性从句则通常用whether/if 来引导: I’m sure that he is honest. 我肯定他是诚实的。 I’m not sure whether/if he is honest. 我不敢肯定他是否诚实。 5.介词后一般不接that引导的宾语从句,但介词except及in除外。 His report is correct except that some details are omitted.  除了有些细节未提到之外,他的报道是正确的。 Criticism and self-criticism is necessary in that it helps us to correct our mistakes.  批评和自我批评是必要的,因为它能帮助我们改正错误。 一 二 6.否定转移 在宾语从句中,主句的谓语动词(词组)是think、believe、suppose、imagine、consider、expect、guess、be sure等,且主句的主语是第一人称并为一般现在时,对宾语从句的否定一般转移到主句上,表示说话者提出一种委婉的看法或主张。 I don’t believe I’ve met you before. 我认为我没有见过你。 I don’t think you will be late.我认为你不会迟到。 Ⅰ Ⅱ Ⅰ.完成句子(高考真题变式训练) 1.The best moment for the football star was 　he scored the winning goal.  2.Some people believe
