b. 名词性从句(Noun Clauses)
8 v" Y2 p& P: h 在句子中起名词作用的句子叫名词性从句。名词性从句的功能相当于名词词组,它能在复合句中作主语、宾语、表语、同位语等。根据它在句中不同的语法功能,名词性从句分为主语从句、宾语从句、表语从句和同位语从句。在名词性从句中,连接词that既没有实际意义,又不充当任何成分,只起引导从句的作用, 引导宾语从句时经常省去。4 F; T2 c# ?% ]8 @$ x8 o
一、主语从句 (The Subject Clause):在复合句中作主句的主语。为保持句子结构平衡,主语从句通常被置于句末,而用it作形式主语。
1 M& \$ {* |9 J2 |2 `$ d That light travels in straight line is known to all.
" P7 Y" P% r5 a4 l m8 ]8 C- F0 i8 t When the plane is to take off hasn’t been announced.+ x$ L- j8 Q5 [, @

1 J. n9 ^, J% a5 b It is still unknown which team will win the match.$ Z& U$ Z1 W3 x- [+ D; s9 o! K, v7 y
二、宾语从句 (The Object Clause):主要作及物动词的宾语,有时置于介词或形容词之后。/ g' H. ]$ {' G
He said (that) his father had come back from the United States.$ @) \! o& N. U6 R- f* s9 p
He asked how much I paid for the violin.
" r. \+ d2 u) R No one can be sure what man will look like in a million years.: J) R; S/ P+ \1 v
如果宾语从句带有补足语,通常用it作形式宾语,而把宾语从句置于补足语之后。
