网友的问题应该做个修正：动词+名词宾语+宾补。不考虑不定式或that从句做宾语。

这时宾语在二种情况下通常后移至宾补之后：

1 宾语较长。宾补是动词要求的，是使动词语义完整的必不可少的部分，因此宾补不能距离动词太远，导致读者误解动词意义。这是宾语过长而需要将宾语后移的本质上的原因。于此同时，宾语如果是个新信息，需要更多的修饰，也是宾语长的原因，句末通常是信息中心，这也是较长的宾语后移至宾补后句末信息中心位置的原因。多长的宾语算较长的宾语呢？通常是名词带后置修饰语（介词短语，非谓语动词或定语从句作后置定语）。例如：

 They painted green all the walls around the house. 宾语walls带有后置定语。这时，宾语后移可以避免作宾补的形容词和后置定语的词项造成误读。原则是宾补不能离动词太远，不能超出眼球不移动的情况下的一个视野范围。

2 突出、强调宾语。句末是信息中心位置，即使名词只是一个词，也可以将宾语后移至句末予以强调。例如：

He pushed the door open. 正常说法。

He pushed open the door. 强调宾语。

有人说，在“宾语+宾语补语”结构中，如果宾语较长，则宾语补语可以放在宾语之前。

我对此有两个疑问：

一是：这个说法对吗？

解答：这个说法是正确的

二是：如果对，那这里所说的“较长”如何界定呢？多长算较长？

谢谢专家！

解答：当宾语由：不定式/动名词/that从句充当，且后面带有宾补时，需要把宾补提前，然后再加1个形式宾语it(简称为6123结构）

主语+think/find / make /feel/believe/consider+it+adj./n+（doing/to do/ that）从句

She considered it important that everything should be finished by eight.

备注（1）cut short 这里为短语动词结构“意思中断；缩短；简化”。后面可以直接接宾语，而还有被动语态。(主语+cut out +宾语 属于主谓宾结构，不是属于主谓宾补+宾语结构）

备注（2）主语+paint+宾语+宾补（这个才是真正主谓宾+宾补）结构

（paint后面接形容词复合宾语,paint sth+adj.）

他把大门漆成绿色。

备注（3）如果宾补为形容词/名词/副词/介词短语。宾语和宾补存在一种“逻辑上主系表”关系，如果宾补为“不定式/动名词/现在分词，或者，则存在逻辑上主谓关系”
