With spanish homework, ten points to best answer with spanish homework? what is imperfect and preterit? explain when to use the imperfect and preterit. be sure to support your description with at least 2 examples in spanish for each topic.

While there are specific times to use both, I find that imperfect is used when there is no definite stopping place or if the action is a continuing thing in the past. While the preterit is a one time action- starts, stops. 

Cuando hablaba, me estornudó. 

When I was walking (it's just a continuing action in the past), I sneezed (happened and ended). 

Cuando era un niño, mi mamá murió. 

When I was a kid, my mom died. 
Being a kid is the underlying action, 'died' is the singular action that began and ended. hope this helps :)

Can you write the question correctly?
