1. “Due to a serie of events” → “Due to a series of events”: “Serie” is incorrect; the correct plural form is “series.” 2. “It has started pretty late” → “It started pretty late”: Past simple is more natural here. 3. “Whatever I do on weekends” → “What I usually do on weekends”: More natural phrasing. 4. “Read news” → “Read the news”: “The news” is the correct collocation. 5. “Even though my dog has just become” → “Even though my dog has recently become”: “Recently” is more natural than “just” in this context. 6. “Moves a lot” → “Is still very playful and active”: More descriptive. 7. “Since some time ago my knee has started to hurt” → “My knee has started hurting for some time now”: More natural phrasing. 8. “Nowadays, the one most athletic is her” → “These days, she is the more athletic one!”: More natural word order.
