下面是2015年高考全国卷1 阅读理解C篇中的一道题，当年难倒了一大批考生。
The fine selection of the major works was done in close collaboration (合作) with the Museo Nacional Reina Sofia in Madrid, Spain, and with contributions from other institutions like the Salvador Dali Museum in St. Petersburg, Florida.
31. What does the word "contributions" in the last paragraph refer to
Artworks. B) Projects. C) Donations. D) Documents.
高考 全国卷I 2015 阅读 [解析]根据前一句句意及关键词The fine selection of the major works，可推知contribution在文中的含义为“作品”。而高中生在英语学习中，最常接触到contribution的释义是“贡献”，如果以此释义来解释contribution， 就会导致学生误选失分。[答案] A
[词源解析]说到contribute，还得挖挖tribute。three →tri,意为“三”。古罗马有三个部族(Tites, Ramnes, and L uceres), 所以“部族;部落”这个单词叫做tribe。 部落要向帝国捐献、进贡，于是产生了tribute，意为“贡品:颂词”;后来tribute又演变成‘提供贡品”，其作为词根，被赋予了“给与;捐献”的含义。con-意为“一起(together)”,是前缀com-的变形， con- + tribute， - 起捐献，有点类似现在常说的“众筹”
