问题描述：
单选The secong book was __ by August 1952,but two years later,the end was still nowhere insight.
A.completed B.to have completed C.to complete D.to have been completed
为何不选D?
答
首先这句话可以翻译为：第二本书原定于1952年8月完稿,但是直到两年以后也没有看见书的结尾部分.
答案C.to complete.
be to+ 动词原形 表示即将做,是对将来的一种决定.
对于D,be to have been completed,这种搭配是不存在的.
因为能力有限只能说到这里,希望对你有所帮助.
