u/1E-12

In the title sentence

人们用了三年时间建 好了这座大桥

How does adding or removing “时间” change the overall meaning?

Thank you!

每次吃饭，他都得边吃饭边喝水，一直说“辣”

Can someone please provide some explanation for the phrase "得边吃饭边喝水"? Translates roughly to mean "drink water while eating".

Is this a common structure? I'm having trouble internalizing this one.
