keep an eye on my luggage
看下我的包
look 多指短暂地看，老外常说 look 来吸引别人的注意力。老师想让学生们看黑板就会说 look at the blackboard ，看那里就是 look over there.
我们请别人帮忙看下包，不是把眼神放到包上，让他们欣赏你的包有多好看那么简单，而是让他们照看好你的行李，别让人偷走了。所以会用到这个短语 keep an eye on...
We often use this when asking people to watch, protect, or take care of somebody or something for us.
我们经常用这个表达来要求别人帮我们观察、保护或照顾某人或某事。

需要注意的是这里的“包”也不单单是指 bag，根据具体的情景有时要说成行李luggage或者suitcase更合适.
