4、、主语从句的引导词 1. 连词 that、 whether, 在主语从句中不充当任何成分, 只起连接作用, 不可省略, 其中 that 没有词义, whether 表示“是否”, 但是不能换成 if。 2. 连接代词 what、who、which, 在主语从句中充当主语、宾语、表 语, 不可省略。 3. 连接副词 when、where、how、why, 在主语从句中作状语, 分别表 示时间、地点、方式、原因等, 不可省略。 另外, wh-+ever, 如 whoever、whatever、whichever 等也可引导主语从 句。在句中充当主语、宾语、表语等, 不可省略。 三、it 作形式主语

5、的主语从句 在主语从句中如果主语太长, 宾语或表语又太短, 为了避免头 重脚轻, 保持句子平衡, 通常会采用 it 作形式主语, 真正的主语从句 放在后面。 常见的使用 it 作形式主语的结构: It is said/reported/believed/well known that. . . It is a pity that. . . It is probable that. . . It happened that. . . It is no wonder that. . . . . . 四、主语从句的语序时态问题 主语从句和其他名词性从句一样必须使用陈述语序, 尤其是当 主语从句是疑问

6、词引导的时候, 主语从句的语序仍须使用陈述语序。 Who/Whom he will go to Beijing with remains unknown. 他将和谁一起去北京还不知道。 主语从句的时态根据具体语境来确定, 尤其是当 when 引导主语从句 的时候, 有些同学会和 when 时间状语从句混淆而误用现在时表将来。 When he will come back is still unclear. 他什么时候回来还不清楚。 五、主语从句的主谓一致 主语从句作主语相当于名词, 和非谓语动词的动词-ing 形式或者 不定式作主语一样看作单数, 句子谓语应该使用单数形式。 That you

7、dont like him is none of my business. 你不喜欢他不关我的事。 What the doctors really doubt is whether my mother will recover from the serious disease soon. 医生怀疑的是我的妈妈是否不久就能从这场重病中恢复过来。 三、After-class 教师活动： 【语法主题应用】 学了“A pioneer for all people”这篇课文后, 你有何感想? 谈 谈你的收获, 至少使用三个主语从句。 _ _ _ _ 【参考范文】 Firstly, what moved

8、me most was Yuan Longping s determination to tackle the crisis of the serious shortage of food and his dream to feed more people in the world.
