【分析】
首先通读全文，理解文章围绕抽象艺术展开，再逐个分析每个空格的考点：15题需用序数词修饰century表“二十世纪”；16题考查expect的固定搭配；17题考查be interested in的固定短语；18题考查one of结构中形容词最高级的用法；19题考查被动语态的时态；20题考查介词后接动名词；21题考查so...that固定句型；22题考查feel的名词形式；23题考查形容词性物主代词；24题考查元音音素开头单词的冠词用法。
【解析】
15. 考查序数词。“in the + 序数词 + century”是固定表达，twenty的序数词为twentieth，故填twentieth；
16. 考查固定搭配。expect sth to do sth是固定搭配，意为“期待某事发生”，故填to be；
17. 考查固定短语。be interested in是固定短语，意为“对……感兴趣”，故填介词in；
18. 考查形容词最高级。“one of + the + 形容词最高级 + 可数名词复数”表示“……中最……之一”，famous的最高级是most famous，最高级前需加定冠词the，故填the most famous；
19. 考查被动语态。主语many of his paintings是动作call的承受者，时间为today，故用一般现在时的被动语态are called；
20. 考查非谓语动词。by是介词，后接动名词作宾语，故填using；
21. 考查固定句型。so...that...是固定句型，意为“如此……以至于……”，引导结果状语从句，故填that；
22. 考查词形转换。his后需接名词，feel的名词形式是feelings（表多种情感用复数），故填feelings；
23. 考查物主代词。修饰名词works需用形容词性物主代词，they的形容词性物主代词是their，故填their；
24. 考查冠词。important是以元音音素开头的单词，表泛指“一个重要部分”，故用不定冠词an。
【答案】
15.twentieth 16.to be 17.in 18.the most famous 19.are called 20.using 21.that 22.feelings 23.their 24.an
