What's the correct word division of this sentence? I don't understand how I should understand this sentence word by word: 农夫过去一看. Without "guo4" everything is clear for me, since "qu4 yi2 kan4" means "to take a look".

But with "guo4" I don't know if it's "Nong2fu1 guo4qu4 yi2kan4" - in this case I don't understand what "yi2" is doing here - or "Nong2fu1 guo4 qu4yi2kan4" - then I don't understand the role and meaning of "guo4". The whole sentence must mean "The farmer came to take a look"... The whole context: 


  老虎倒在了芦苇丛里。农夫过去一看，老虎前胸插着箭。
The sentence describes a two parts action.

&quot;农夫过去一看&quot; means &quot;the farmer went over and took a look&quot;


农夫 the farmer

过去 went over

一看 took a look



过 is a verb for &quot;go over&quot;  e.g. 过美国 (go over to The United States)
去 is the directional verb particle that indicates which direction the subject is going over
&quot;过去美国&quot; (go over to The United States) is different from &quot;过来美国&quot; (come over to The United States); it is &quot;农夫过去一看&quot; (the farmer goes over and take a look), not &quot;农夫过来一看&quot; (the farmer comes over and take a look)

一看 is a more literary style of saying 看看 or 看一看
Note:
过去 (v): go over
过去 (n): past
