Question

我在做英语题时有这样一个句子：Some photos taken by children.

请问这里面的taken是表示被动的吗？如果是，那能否直接用被动语态，写成are/were taken?

Answer 1

答：作为一个单独的句子，这是错误的。因为它不是一个句子，而是一个名词短语。
但在有上下文时，它又可能是一个正确的省略句：
.—What are on show in the museum?
--- Some photos _____ by the children of Yushu,Qinghai.
A.taken B.are taken
本题选A。
译：在博物馆里展出的是什么？
一些由青海玉树的孩子们拍的一些照片。
是的，过去分词表示被动和完成。这里是过去分词taken by the children作后置定语，相当于定语从句：which/that were taken by the children of Yushu, Qinghai.
这个回答如果完整的话是：
Some photos taken by the children of Yushu, Qinghai are on show.

如果填B或C.
Some photes are/were taken by the children. 倒是一个完整的句子。但不符合对话。
人家问的是博物馆里在展览什么？
你回答一些照片被人拍了。不是答非所问吗？

Answer 2

可以，但区别：

Some photos taken by children are very beautiful . (
Some photos are / were taken by children.

加油！不明白再问！如果帮到你，请采纳，谢谢！

追问

请问后置定语是什么？

Answer 3

taken是过去分词做定语,
take与photo时被动关系，所以用过去分词。相当于定语从句some
photos
which
are
taken
by
the
children

Answer 4

首先，你说的句子其实是一个短语，taken by children 是过去分词短语做后置定语，
这里的确是表被动，可以改成some photoes which are taken by children.

Answer 5

taken by children 是photo 的后置定语，表被孩子们照的照片。

如果加上Be动词are. were 的话 原文就从词组变成了句子。
