【分析】
这是一道英语语法填空题，需结合语境、固定搭配及语法规则逐一解题。思路如下：15空考查固定搭配be famous for，表“因……而著名”；16空主语she与动词admire是被动关系，描述客观事实，需用一般现在时被动语态；17空表演出的目的，用不定式作目的状语；18空泛指“一首热门歌曲”，用不定冠词；19空连接并列动作，用并列连词；20空修饰动词sing，需用副词；21空为定语从句，先行词指人，选合适关系代词；22空考查固定短语to one's surprise，用名词所有格；23空修饰名词song，需用形容词；24空考查固定搭配can't help doing sth.，用动名词。
【解析】
15. 固定搭配be famous for，故填for；16. 主语she是admire的承受者，时态为一般现在时，故用is admired；17. 此处表目的，用不定式to raise；18. 泛指“一首热门歌曲”，hit以辅音音素开头，用不定冠词a；19. 前后为并列动作，用连词and；20. 修饰动词sing，用副词directly；21. 定语从句先行词为指人的someone，关系代词用who/that；22. 固定短语to one's surprise，用audience的所有格audience's；23. 修饰名词song，用形容词traditional；24. 固定搭配can't help doing sth.，故填thinking。
【答案】
15. for；16. is admired；17. to raise；18. a；19. and；20. directly；21. who/that；22. audience's；23. traditional；24. thinking
