例如:"It is important for us to study hard."(我们用尽力学习很重要。

语法专题 1
名词性从句与连接词
主语从句、宾语从句、表语从句和同位语从句在复合句中的作用相当于名词,因此这四种从句统称为名词性从句。
我们根据从句应用的位置,可基本判定从句的类型: ①That/Wh-(主语从句)+ v. …
②It (形式主语) + v. …+ that/wh-(主语从句) ③… + vt. + that/wh-(宾语从句) ④… + prep. + that/wh-(宾语从句) ⑤… + be/系动词 + that/wh-(表语从句) ⑥(… +) n./pron. + that/wh-(同位语/定语从句) ⑦状语从句 ,S + P (主句)
⑧S + P (主句) ,状语从句/非限制性定语从句
从句要用陈述语序,即:连接词 + S. + V .。
引导名词性从句的连接词有三类:从属连词、连接代词和连接副词。
(1)、从属连词
它们在从句中只起连接作用,不充当任何成分。
(2)、连接代词 (wh-引导的从句原来是特殊疑问句,wh-引导词很多还保留着原来在疑问句中疑问的含义) 它们都有各自不同的含义,除了起连接作用外,还在从句中充当主语、宾语、表语或定语等成分。
(3)、连接副词 (
wh-引导的从句原来是特殊疑问句,wh-引导词很多还保留着原来在疑问句中疑问的含义) 它们也都有各自不同的含义,除了起连接作用外,还在从句中作状语。
名词性从句和连接词的运用如何用从句作为名词的一部分名词性从句是指在句子中充当名词的从句,它可以用来作主语、宾语、表语、同位语等。
