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.
C.Rarely seen非谓语动词作原因状语，see与逻辑主语the white mountain goat 为动宾关系，故用过去分词作状语。
同意楼上选C 不用强调正在被看见
选D，现在分词作伴随状语表示经常持续的状态，表示山羊不易被发现的意思。而A是用的完成时态，所以不行。B的不定式表示目的，也不行；C直接是个过去分词当然更不行了，只能选D。像这种类型的题，建议同学你多做做，慢慢就会有鱼感了，希望我的回答能为你解惑，谢谢！...
