Question

During the Spring Festival, paper cuttings __________ on windows, doors and walls as symbols of wishes for good luck and a happy new year.

A. are put B. were put C. puts D. putting

Answer

A

【解析】

句意：在春节期间，剪纸被贴在窗户上、门上和墙上，象征着对好运和快乐的新年的祝愿。

由句意知paper cuttings和put on之间存在被动关系，需使用被动语态；又因为每年都过春节，所以应用一般现在时；are put一般现在时态的被动语态，were put一般过去时态的被动语态，puts动词单数，putting动名词；故选A。
