8. All of the flowers now raised here have developed from those __________ in
the forest. (1997上海卷)
A. once they grew B. they grew once
C. they once grew D. once grew
答案是c还是d呢 为什么

选c,
因为你要是用d的话那后面的也构不成定语从句,没有主语,起码也需要用过去分词做后置定语啊,而grew只是个过去式啊.而c正好可以构成定语从句,从句中缺宾语,因而关系代词that给省略了,如果这个句子结构需要我划分的话,再联系我哦.

你好,这题的正确答案是C,
首先,THOSE后面跟的是一个定语从句,
D是一个过去式,只能作谓语,而这个句子已经有谓语have developed 了,所以是错的.
