``动词``填空

短语：record sth./sb doing sth.
所以填inventing

楼上的胡说
这里说的是“根据纪录火药是中国人发明的”。by the Chinese,所以用被动语态，所以应该填invented.

invention...

to be invented . 楼上的都胡说
短语：record sth./sb doing sth. 当然可以，但在被动句中必须用to do.
eg.
The history records chinese inventing gunpowder.
but:
Gunpowder is recorded to be invented by the chinese.
We considered him having a lovely voice.
but::
He's considered to have a lovely voice.
