PAST TENSE 
The simple past is a verb tense that is used to talk about things that 
happened or existed before now. Imagine someone asks what your 
brother Wolfgang did while he was in town last weekend.
 
Fortunately, there is a formula for making simple past verbs negative, and 
it’s the same for both regular and irregular verbs (except for the verb to 
be). The formula is did not + [root form of verb]. You can also use 
the
 contraction
 didn’t instead of did not. 
Example: Wolfgang did not brag too much about his hula hoop skills.
Wolfgang’s girlfriend didn’t see the contest. 
The formula for asking a question in the simple past tense is did + 
[subject] + [root form of verb]. 
Example: Did Wolfgang win the gold medal or the silver medal?
Where did Wolfgang go to celebrate? 
Did the judges decide fairly, in your opinion?
