Давайте разберем вашу задачу и перепишем предложения, преобразовав слова в скобках в Present Simple. В конце каждого предложения добавим "НП" (неправильное):
Mary sees Peter standing at the bus stop. НП
Mary: Hello, Peter. What bus you wait for? НП
Peter: Hello, Mary. I wait for a 9 or a 14. НП
Mary: You usually go to work by car, don't you? НП
Peter: Yes, but the car belongs to my mother and she sometimes wants it. НП
She uses it today to take Bob to the dentist. НП
Mary: I usually go by car too. Jack takes me because he passes my office on his way to the factory. НП
But this week he works in a factory in the opposite direction, so I queue like you. НП
Peter: Here's a 9 now. You come on it or you wait for a 14? НП
Mary: I think I'll take the 9. If I wait for a 14 I may be late, and if you are late at my office everyone looks at you. НП
Теперь все предложения написаны в Present Simple, и "НП" добавлены в конец каждого. Если у вас есть дополнительные вопросы или требуется больше объяснений, дайте знать!
