下文的信息。故选G项。

20．答案　E

解析　根据空前一句可知，了解艺术家是欣赏其艺术画作的第一步。E项中的Learning something about the artist(了解艺术家)与之相呼应，故选E项。

21．答案　B

解析　根据下文中的"There are different styles and types of art mediums，realism，surrealism，and impressionism，to name but a few."可知，艺术有不同的风格以及不同的表现方法，后文则具体地介绍了不同的风格和表现方法，由此可知本段主要是关于艺术风格和表现方法的。本空位于段首，所以本空为总结句，对下文进行概括。故选B项。

22．答案　F

解析　根据空前一句可知，通过阅读线条和颜色来理解艺术家的心思很难，而空后则提出了一些简单的指导方法。所以本空与不同的人对艺术品有不同的理解有关，故选F项。

24．答案　C

解析　根据空前一句"Not every work of art will catch your eyes or emotions at first sight."可知，并非每一件艺术品都能让你第一眼便被吸引或激起你的情感，空后一句则提到了让读者用眼睛去探索，所以本空为过渡句，C项(理解某些艺术品会需要一些时间。)符合语境。
