【解析】文章介绍了丝绸在中国的发明及丝绸技术向国外的传播的过程。

【1】考查主谓一致。主语为“raising silkworms for silk production”，动名词作主语，谓语动词用第三人称单数形式，故该空填has。

【2】考查固定句式。be doing sth….when…意为“正在做某事这时突然……”，是固定句式。

【3】考查非谓语动词。主语she和realize之间是主动关系，故用现在分词作伴随状语。

【4】考查副词。later是副词，意为“后来，以后”，在句中作状语。句意：她教给人们如何养蚕，后来发明了织布机。

【5】考查冠词。level是可数名词，该处指“一个较高水平”，故该空填不定冠词a。

【6】考查反身代词。keep sth. to oneself意为“保密，不和他人分享”，故该空应填they的反身代词themselves。

【7】考查名词。one of+复数名词，意为“……之一”，故该空应填复数名词。

【8】考查介词。a symbol of意为“……的象征”。

【9】考查副词。句意：蚕丝业慢慢地从亚洲到达了欧洲。slowly是副词，修饰动词reach。

【10】考查被动语态，时态和主谓一致。句意：现在，大部分丝产自长江三角洲南部。时间状语为now，故该句应用一般现在时态。主语most of silk和produce之间是被动关系，故该空应用被动语态，且most of silk是不可数形式，根据主谓一致原则，该空填is produced。
