to have finish the book是什么结构？
原题是这样的：His new book will be published next month. It took him a year to have finish the book.
我也觉得没有这种说法。直接to finish就可以了，你的原句应该不正确。
to have finish 没有这种说法。原句应是： His new book will be published next month. It took him a year to finish the book. 他的新书下月即将出版。完成这本书花了他一年的时间。 to finish the book是不定式短语，在句中作主语，it是形式主语。
to have finish the book是后面句子的真正主语。It做形式主语 全句意思是：他的新书下个月即将出版。完成这本书花了他一年的时间
