Use of 時 with different verb conjugations


Im learning the use of 時 and it's a wee bit confusing.

I get the difference between

  * 食べる時、お酒を飲む
  * 食べた時、お酒を飲む

But the difference between

  * 食べる時、お酒を飲む
  * 食べている時、お酒を飲む

eludes me. Are they the different ways of saying the same thing? I drink
alcohol when eating/when I eat?




食べる時お酒を飲む can mean, as you say, you habitually drink alcohol in eating, and
besides that, you drink it just before eating. That part is the difference
between 食べている時お酒を飲む, which means you drink it in the course of eating.
