25、,要写好名词性从句就很容易了。什么样的名词性从句就应该置于什么位置。但是使用名词性从句主要应注意其引导词的用法与区别、何时用it作形式主语或形式宾语来代替真正的主语从句或宾语从句等。(1) He told a lie to everyone. It is wrong. (合并成一个复合句)That he told a lie to everyone is wrong.(2) That he told a lie to everyone is wrong. I think(合并成复合句)I think that he told a lie to everyone is wrong. 若宾语从句后
26、还有补足语,要用 it作形式宾语,而把宾语从句放在句尾。根据英语语言表达方式,如果主语从句或宾语从句太长,可用it作形式主语或形式宾语,真正主语和宾语置于后面,则得出该句最标准的语表达句式:I think it wrong that he told a lie to everyone.(3) Something was going on in the art. They were interested in it.(合并成一个复合句)两句合并成一个句子,首先语义上要符合逻辑,这样可以确定主从句;再根据语法结构及连词的用法表述句子,得出该句为:They were interested in what was going on in the art. (宾语从句)或为:They were interested in something that was going on in the art.
