题目解答
答案
这道题考察的是英语语法中主谓一致的问题。我们需要选择一个合适的动词形式来填空，使句子的主语和谓语在人称和数上保持一致。
句子的主语是 "Her mastery of the language"，这是一个单数名词短语。因此，谓语动词也应该是单数形式。
原句是：
Her mastery of the language __ (demonstrate) her interest in the country's culture.
分析：
1. 主语 "Her mastery of the language" 是单数形式。
2. 谓语动词 "demonstrate" 的单数形式是 "demonstrates"。
因此，正确的填空应该是 "demonstrates"。
完整句子：
Her mastery of the language demonstrates her interest in the country's culture.
答案：
demonstrates
