Course: English II

UNIT 1: SIMPLE PAST – REGULAR VERBS (INTERROGATIVE FORM)
INTRODUCTION: ASKING QUESTIONS IN A FORENSIC INVESTIGATION.
When forensic investigators analyze a case, they need to ask questions to reconstruct events. To do this in English, we often use the interrogative form in the Simple Past.
We use DID + subject + base verb to ask about past actions.
EXAMPLES in a forensic context:
•	Did the suspect enter the building? 
•	Did the witness observe the incident? 
•	Did the officer arrive on time? 
•	Did the driver stop at the crossing?
Important Rule!
Even though the question is in the past, the verb stays in base form:
Did the driver stopped? (wrong)
Did the driver stop? (right)
