her award 和 the award 或者an award：

本句用这3个都对，只是意思有所不同。

She's been getting a bit above herself since winning her award.

She's been getting a bit above herself since winning the award.

She's been getting a bit above herself since winning an award.

自从获奖以来，她变得有点忘乎所以了。

虽然中文翻译可以相同，但区别就在这三个限定词上。

1. 物主代词强调奖励属于她的。

2. 定冠词表示特指那个奖励。

3. 不定冠词表示一次奖励。

又如，以下例句都是正确的：

I lost my pen. 

I lost a pen.

I lost the pen.
