第29题:[单选题]In 1913,Frost’s first book of poems, A Boy’s Will, ________ by a famous publishing house and became a great success later. A.have been published B.has been published C.were published D.was published 参考答案:D
【详解】 考查时态和语态。句意：1913年，弗罗斯特的第一本诗集《男孩的遗嘱》由一家著名出版社出版，后来获得了巨大成功。A. have been published 已经被出版（现在完成时态的被动语态）；B. has been published 已经被出版（现在完成时态的被动语态）；C. were published 被出版 （一般过去时态的被动语态）；D. was published 被出版 （一般过去时态的被动语态）。分析句子结构可知，空处为句子的谓语动词，根据and后面的became可知，句子用一般过去时态。句子的主语和谓语动词之间为动宾关系，所以要用一般过去时态的被动语态。主语为单数，谓语动词使用第三人称单数形式。故选D。
