为什么可以说a time、a long time（time是不可数名词啊）

time 是不可数名词，但是为什么可以说 a time、a long time 呢？为什么可以用a？

▲time并不是永远不可数。当它表示抽象意义的“时间”时，它确实不可数。如：

Time heals all sorrows. 时间可以消除一切忧伤。

Time is our most valuable commodity. 时间是最有价值的东西。

Time permitting, we’ll come and see you. 如果时间允许，我们就来看你。

▲但如果表示“一段时间”，则可以连用不定冠词。如：

He left a short time ago. 他刚刚离开不久。

We had a nice time at the beach. 我们在海滨时开心极了。

It’s a long time since I saw Rachel. 自我见到雷切尔以来已有很长一段时间了。

For a brief time they had shared a room in hall. 曾有很短一段时间他们合住过一间学生宿舍。

After qualifying in medicine, he worked for a time at City Hospital. 取得医生资格后他在市医院工作了一段时间。

time 是不可数名词，但是为什么可以说 a time、a long time 呢？为什么可以用a？

【1】当time表示相当长的一段时间，或者说是经历的一段时间，时期为可数名词，可以在前面加不定冠词。

(英文解释： If you say that something has been happening for a time, you mean that it has been happening for a fairly long period of time.)

He was also for a time the art critic of 'The Scotsman'.

有相当长的一段时间他为《苏格兰人》报撰写艺术评论。

He stayed for quite a time.

他呆了相当长的一段时间。

孩子们不在的时候，我和萨拉度过了一段美好时光。

She's had a really tough time the last year and a half.

这一年半以来，她度过了一段非常艰难的时期。

【2】当time表示历史时期;时代,当代;时代潮流还可以使用复数形式并于定冠词the连用。

(英文解释：times are used to talk about a particular period in history or in your life.)

They were hard times and his parents had been struggling to raise their family.

那是段艰苦时期，他父母一直艰辛地养家糊口。

We'll be alone together, quite like old times.
