新概念二82课中：Such creatures have rarely been seen alive by man. 其中alive的用法
新概念二中有一句：Such creatures have rarely been seen alive by man as they live at a depth of six hundred feet.
这句话我有点糊涂：
1.alive在这里是形容词吗,属于什么用法?
2.这句话如果用主动句如何表达?
谢谢!
再问一个问题：这里man为什么用单数？是否可以用men?
谢谢！
答
1.alive在这里是形容词吗
是的
属于什么用法?
形容 Such creatures
2.man rarely comes across(gets to see) such creatures when they are alive,...
3.man 是集体,就像 mankind
