问题 The second book was______by August 1952, but two years later, the end was still nowhere in sight.

选项 A、completed
B、to complete
C、to have completed
D、to have been completed

答案 D

解析 was to have been completed by August 1952意为“本来按计划要在1952年8月前脱稿的(但并没有如期完成)”。be to do sth.表示打算或按计划要做某事;后面跟不定式完成时表示“按计划本来要做某事(但后因故未做)”。
