高三选择题

因为agreement自己不能intend，
是人们intend。

补充完整后应该是
The international agreement,THAT IS INTENDED TO encourage children not to smoke and help people kick the habit,was sighned on February 27.

是选D吗?是的话to intend to表目的
你可以这样来看
To intend to encourage children not to smoke and help people kick the habit, the international agreement was sighned on February 27.
中文就是为了想要鼓励孩子们……，所以……被签署了，省略号的部分我没翻译

我也认为是第4个，表示目的，为了鼓励孩子们。。。。。。
中间这些都是插入的语句。主句是协议被制定，我个人认为。

补充完整后应该是
The international agreement,which was intended to encourage children not to smoke and help people kick the habit,was sighned on February 27.
理由一楼说得可以，我觉得应该选C

选C agreement是被人发出 的 不能主动

我认为应该选C 这一题是个宾语从句 The international agreement,（____encourage children not to smoke and help people kick the habit,）was sighned on February 27.中间括号内的是对“the international agreement”的解释说明，完整的是：(which was) intended to encourage children not to smoke and help people kick the habit.这个which was 可以省略掉，自然就成了 The international agreement,intended to encourage children not to smoke and help people kick the habit,was sighned on Feb. 27.

回答：非限制性定语，要求用被动语态的现在分词短语所致。选B。

我认为应该选C be intended to 专为．．．．设计的．和主语关系为被动，用过去分次做状语．
