第05讲 名词性从句 1. 掌握名词性从句的三要素和类型判定。 2. 掌握名词性从句中引导词的意义和用法 1. 引入： 有一个包括5个that的英语句子对吗？ He said (that) that "that" that he used was wrong. I think that that “that ” that that student wrote on the blackboard was wrong. 2. 定义： 英语名词性从句成分是根据从句在主句中的位置划分的，任何一个句子，一旦处于主句某个成分的位置上，它就成了相应的.....语从句。 二. 引导词的作用： 1. that 2. if/ whether 3. who/whom/whose/what 4. why/where/when/how/how many 连 词 that/whether/if /because 连接，不在从句中作成分 连接代词 what/which/who/whom/whose/whatever/… 连接且作主、宾、定语等 连接副词 when/where/why/how 连接且做状语 注意： 1．what引导名词性从句时，意为“什么”或“……的”，在从句中用来作主语、宾语、表语或定语。 2．wh－ever引导名词性从句时，其作用等同于其前面的连接词，意为“任何……”或“无论……”，含有强调的语气。 三．名词性从句分类: 名词性从句的判断：根据从句在整句话所作的成分来判断。 1. When we will start is not clear.________从句 2. Mrs. Black won’t believe that her son has become a thief.___________从句 3. My idea is that we should do it right now. __________从句 4. We heard the news that our team had won. ___________从句 注意：名词性从句高考考查 ①引导词的选择与判断；在主语从句中只能用whether，不能用if ②词序：陈述语序； ③时态：注意主从句时态的呼应 四．名词性从句三步曲：一分二划三看 1. “一分”即分清从句类型 2、 “二划”即划分出从句（用括号表示从句） 3、 “三看”即看从句句意是否完整 1） 句意不完整，选连接代词 2） 句意完整，选连接副词 考点一：主语从句：在句中充当主语的从句叫做主语从句。 1. That he will come here on Wednesday is certain. 2. Whether he will come here on Wednesday is not certain. 3. What he said is not true . 一般来说主语从句都是放在句首，但有时为了使句子保持平衡，避免"头重脚轻"，常用it作形式主语，从而把主语从句放后面。常以it作形式主语的句型有： 常考考向1：在实际应用中，常用it作形式主语，而将真正的主语that从句后置 It + be + 形容词 ＋ that从句 It is necessary/ important /that… 有必要/重要的是… 注意：此时从句语气要用虚拟语气：(should) +v.(原形)，should可以省略。 Eg. It is necessary that a new plan should be designed at once. It + be + -ed分词 ＋ that从句 It is believed/said that… 人们相信/说… It is known to us/all that …. 众所周知… It has been decided that…… 已经决定…… Eg. It’s reported that no one was killed in the earthquake. 拓展：It is suggested that…“建议…” 从句用虚拟语气(should + v.原), should 可以省。 It was suggested that we should start earlier at the meeting. It + be + 名词/形容词/过去分词 ＋ that从句 It is common knowledge that… …是常识 It is a surprise/pity… that …. 令人惊奇/遗憾的是… It
