Past simple (verleden tijd) must be used when we describe something that took place in the past at a specified time. ( yesterday/ last year/when I was at the cinema etc.)
- The past tense of regular verbs is formed by adding -ed to the verb.
- If the verb ends in -e, only -d is added: notice - noticed.
- In negative verbs and interrogative sentences did is used.
- Irregular verbs do not form their past tense by adding -ed: buy - bought
