・get distracted
・inattention

「注意力不集中」在英語可以用 get distracted 或 inattention 等來表達。

There is something that is bothering me, I get distracted.
（有一些事情在困擾我，我注意力不集中。）

I've been so busy with work lately that I think the inattention is caused by accumulated fatigue.
（我最近工作很忙，所以我想注意力不集中是由於疲勞累積造成的。）
※ accumulated fatigue（疲勞累積）
