To rewrite the given sentences in Simple Past or Present Perfect Tense, we need to understand the use of both tenses.
The Simple Past Tense is used to describe actions that happened and were completed in the past. The action has no relation to the present. Words often used with the simple past tense include 'yesterday,' 'last week,' 'a year ago,' etc.
The Present Perfect Tense , on the other hand, describes actions that occurred at an unspecified time before now or began in the past and continue into the present. It often uses words like 'already,' 'just,' 'yet,' 'ever,' 'never,' etc. This tense connects the past to the present.
Let’s rewrite each sentence accordingly:
Original Sentence : They finished their homework a little while ago.
Simple Past Tense : They finished their homework a little while ago.
Present Perfect Tense : They have finished their homework.
Original Sentence : I wrote my first poem when I was just ten years old.
