Объяснение: The sentences given are a mixture of sentences in Present Perfect and Past Simple tenses. The Present Perfect is used to talk about actions or states that started in the past and are still relevant to the present. It is used to describe experiences, actions that have happened but not specified when, and actions that have started in the past and continue until now. On the other hand, the Past Simple is used to talk about completed actions in the past.
In sentences 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, the verb "haven"t" is used, which indicates the negation of the Present Perfect tense. It means that those actions have not happened or completed at the time of speaking.
In sentences 11, 12, and 13, the Past Simple tense is used. The word "hadn"t" indicates the negative form of the Past Simple tense. It means that those actions did not happen or were not completed within a specific time period in the past.
Пример:
"1. Он не купил новый велосипед. (He hasn"t bought a new bike.)
2. Я не отправил письмо другу. (I haven"t sent a letter to my friend.)
3. Она не сделала очень плохую ошибку. (She hasn"t made a very bad mistake.)
4. Дети не пошли спать. (The children haven"t gone to bed.)
5. Мы не встретились с нашими деловыми партнерами. (We haven"t met our business partners.)
6. Они не убрали свои комнаты. (They haven"t cleaned their rooms.)
7. Туристы не посетили Национальную галерею. (The tourists haven"t visited the National Gallery.)

9. Гарри не сломал свою машину. (Harry hasn"t broken his car.)
10. Мэри не видела этот фильм. (Mary hasn"t seen this film.)"
Совет: To understand the difference between Present Perfect and Past Simple, pay attention to the time expressions used in the sentences. "Hasn"t" and "haven"t" are used for the Present Perfect, while "didn"t" or "wasn"t/weren"t" are used for the Past Simple. Additionally, the Present Perfect is often used with words like "yet" and "already" to indicate whether an action is expected to happen or not. The Past Simple is used with specific time expressions to indicate the completion or non-completion of an action in the past.
