Step-by-step explanation:
Changing a tense from the present to the perfect requires the use of the present perfect tense structure "has/have+ third form of the verb." This means that depending on the subject, we have to insert has/have along with the past participle form of the verb.
The sentences with a changed verb tense are as below-
1. Tony has walked from home to school.
2. Sara has baked potatoes for dinner.
3. Taha has painted beautiful pictures.
4. Afia has talked all the time in class.
5. The baby has cried in its pram.
