亲,动词的过去分词不可做名词,它是有着形容词词性的。
你说的enclosed放在句首有两种情形:一种是the +形容词表示一类人。如The old often feel lone.老年人一般都会感到孤独。
另一种情形是倒装。当形容词位于句首时用倒装结构。如,Enclosed is my daily report.我每天的所写的都是与世隔绝的。
enclosed不是名词,可以这样用是因为前面省略了subject,是一种惯用的形式。
Enclosed is = What is enclosed is / what has been enclosed is
其他例子还有
(what's been) Attached is a pic.
(what's been) Written on the wall is a sign that reads..
Enclosed is my daily report. 这是我每天灰写的,书上也有这种用法,它本身是形容词
adj.被附上的
你那个原句是什么啊?
