Вот как правильно заполнить предложения с использованием Present Perfect или Past Simple:

1. Why hasn’t Jason come to school?
   (Present Perfect используется, потому что речь о действии, которое связано с настоящим моментом — Джейсон до сих пор не пришёл.)

2. Did you have a nice time last Saturday?
   I did. That was an excellent party we had then.
   (Past Simple, потому что событие произошло в конкретное время в прошлом.)

3. I'd love to go to America.
   — No wonder. It's a very interesting country.
   Have you been there?
   — Yes, I was there 3 years ago.
   (Present Perfect для опыта до настоящего момента; Past Simple для конкретного времени в прошлом.)

4. Do you often come to this disco?
   — No, this is the first time I have come here.
   (Present Perfect, потому что речь о событии в жизни до настоящего момента.)

5. I really love this cake. It's the nicest cake I have ever had.
   (Present Perfect с “ever” используется для опыта до настоящего.)

6. Have you been to France?
   — Yes, I have. I have been there twice.
   — Did you like it?
   — Yes, it was super!
   (Опыт — Present Perfect; реакция на прошлое — Past Simple.)

7. They don't have a car any longer. They have sold it.
   They sold it the other day.
   (Present Perfect для результата в настоящем; Past Simple для конкретного времени.)

8. Go and wash your face and hands.
   — But I already have washed them.
   — Sorry, your face is still dirty.
   (Present Perfect для завершённого действия с актуальным результатом.)

9. Have you done the shopping? Have you bought everything?
   — No, I'm sorry. I forgot to take the shopping list.
   (Первые два — Present Perfect, потому что интересует результат к настоящему; “forgot” — Past Simple, конкретное событие в прошлом.)

10. Have you eaten all the sandwiches?
    — Yes, I was so hungry!
    (Present Perfect для действия, завершившегося к настоящему моменту; Past Simple для состояния в прошлом.)

Если хочешь, я могу составить небольшую табличку с правилами, чтобы сразу видеть, когда использовать Present Perfect, а когда Past Simple — это помогает при таких упражнениях.
