1.答案：C.
2.翻译：来访的部长表达了他对谈判的满意,（并且）补充说他很享受/喜欢他的...
3.
1）此题的确是用现在分词adding做伴随状语.
2）此句有两个动词：express“表达”和add“补充（说）”,但是逗号前后并没有and这样的连词连接,说明它只是一个简单句,并非并列句.
而简单句只能用一个动词做谓语（expressed）,所以add只能做状语了,这就要求采用add的非谓语形式了.
考查主语the visiting minister和add的关系为主动,所以用其现在分词形式adding.
3）至于伴随状语的理解,只能根据句子翻译出来后的句意来判断.
4）其他选项中,B指表示目的状语“为了补充说...”或结果状语“结果补充说...”,与句意不符,排除；
A项表明先add“补充说...”,再“表达对谈判的满意”,即动作add发生在expressed his satisfaction with the talks之前,明显不对,排除；
D项用过去分词added,表明主语the visiting minister和动词add之间为被动关系,也明显错误,排除.
