1. Chris didn't gone shopping yet. 2. I has bought that green T-shirt. 3. Paul's friends have ran a marathon today. Have Maria baked a chocolate cake? Has you ever eaten a dragon fruit?

Решение:

1. Chris hasn't gone shopping yet. (Правильная форма Present Perfect: has/have + V3)
2. I have bought that green T-shirt. (После 'I' используется 'have', а не 'has')
3. Paul's friends have run a marathon today. (Правильная форма Present Perfect: have + V3, где V3 от 'run' - 'run')
4. Has Maria baked a chocolate cake? (Подлежащее 'Maria' требует вспомогательного глагола 'Has' в вопросе Present Perfect)
5. Have you ever eaten a dragon fruit? (После 'you' используется вспомогательный глагол 'Have' в вопросе Present Perfect)
