没有的,可以在book后加上that,但这个是可以省略的.from the book 的位置可以放句首或者句末.句子意思不变:我们可以从书中得知空气是很新鲜的.
We can know from the book that in the past the air there was very fresh. 这里,加了that,in the past 表示“在过去”,there 是那儿的意思,最后这个意思你没有要求.
如果,你在上文中已经讲述了具体的过去时间,句子最好说成:
We can know from the book (that) the air then was very fresh.
