【5】inventions

【解析】

本文主要介绍了中国的四大发明。

【1】句意：在宋朝一个叫毕升的人发明了印刷术。因为是在叙述过去发生的事情，故使用过去时，所以答案填invent的过去式invented。

【2】句意：火药在战争中被使用。本句是叙述过去的事情，“they(指火药)”是动作的承受者，作主语。故采用一般过去时被动语态。答案是were used 。

【3】句意：在东汉时期，一个叫蔡伦的人发明了一种新型的纸。分析句子知，本句主谓宾齐全，故需要非谓语动词，分词作定语，所以答案填name的过去分词named。

【4】句意：春秋战国时期发明了指南针。The compass作主语，是动作的承受者，又是叙述过去的事情。故使用一般过去时被动语态，主语是单数。故答案填was invented

【5】句意：中国古代的四大发明，在中国古代史上扮演着非常重要的角色invent动词，发明，创造；其名词形式是invention，因为前面有four故使用其复数形式inventions。
