itispartofmydailylife中part为什么不加a?

Question

it is part of my daily life 中part为什么不加a?

Answer 1

part是比较特殊的名词,即可数又不可数.我们只能特殊认识.
常见重要用法如下：
part n.[c][u] a piece of sth.
* be part of=be a part of
e.g.Falling over is part of learning how to ski.
=Falling over is a part of learning how to ski.
* part of = a part of (一小部分) / parts of （大部分）
两者区别没有的,只是习惯问题.
