Okay, let's put the verbs in the present simple tense!
-
She spends her free time with her friends. They often go to the cinema.
-
Tony doesn't work at weekends. He visits his grandparents in the countryside.
Explanation:
- In the first sentence, 'she' is a singular subject, so we add '-s' to the verb 'spend' to make it 'spends'. 'They' is a plural subject, so the verb 'go' stays as it is.
- In the second sentence, 'Tony' is a singular subject. To make the negative form of 'work' in the present simple, we use 'doesn't work'. Then, since 'he' is a singular subject, we add '-s' to the verb 'visit' to make it 'visits'.
