答案

C
各位同学,在这个句子里面的非谓语动词短语一定是作定语不是状语
非谓语动词短语作定语修饰the white mountain goat,很少有人看见,故用被动Rarely seen,如果改成从句可以说The white mountain goat which is rarely seen,is an extremely sure-footed ...
一般非谓语动词短语作定语的位置都在修饰词后,这个句子把它提前了而已,对比以下两句：
1.The computer centre,opened last year,is very popular among the students in this school．
2.Opened last year,the restored 18th-century plantation is now a boutique.
同理,以上两句也可改成定语从句.因而这个句子是非谓语动词短语作定语的典型例句.
