We will solve this exercise in two ways. First, we will write 5 sentences in the present tense and then 5 more in the preterite tense
Before we start solving this problem let's explain what it is the present and the preterite tense. In Spanish, the simple present tense (el presente or el presente de indicativo) is used to talk about habitual actions, routines, things happening now or in the near future, universal truths, facts, hypotheticals, lapses of time, and for ordering in restaurants and stores. There are both regular and irregular indicative forms.
On the other hand, the preterite tense (el pretérito) is used to describe actions completed at a point in the past. So the Spanish preterite is not used to describe regular or continuous actions in the past with no specific beginning or end. In that case, we use the imperfect. Therefore, we use the preterite to talk about completed actions in the past. So, it is used to talk about beginnings and ends, things that occurred on specific dates or days, at specific times or during specific time periods, and events in a sequence. There are two forms in this verbal tense, namely: Regular Imperfect Forms and Irregular Imperfect Forms.
