1. I have just bought a bright blue mobile phone. (Я только что купил ярко-синий мобильнтй телефон.) Explanation: We use the present perfect tense (have/has + past participle) to talk about an action that happened in the past but has a connection to the present. In this case, the action of buying the mobile phone has just happened, and it still has an impact on the present because the speaker now owns the phone. 2. Have you ever seen a cat without a tail? (Ты когда-нибудь видел кошку без хвоста?) Explanation: We use the present perfect tense to talk about past experiences or actions that happened at an unspecified time before now. In this case, the speaker is asking if the person has had the experience of seeing a tailless cat in their life. 3. My brother has never seen a spaceship. (Мой брат никогда не видел космический корабль.) Explanation: Like in the previous sentence, we use the present perfect tense to talk about past experiences. In this case, the speaker states that their brother has never had the experience of seeing a spaceship. 4. We have not heard your new tape yet. (Мы еще не слышали твою новую кассету.) Explanation: Here, we use the negative form of the present perfect tense to state that the action of hearing the new tape has not happened. The word "yet" adds the idea that the action may still happen in the future. 5. How many words have you written for your history project? (Сколько слов ты написал для своего проекта по истории?) Explanation: Once again, we use the present perfect tense to talk about past actions or experiences. In this case, the speaker is asking about the number of words the person has written so far for their history project. 6. Barbara has not had her breakfast yet. (Барбара еще не позавтракала.) Explanation: Like in sentence 4, we use the negative form of the present perfect tense to state that the action of having breakfast has not happened yet. The word "yet" suggests that it may still happen in the future. 7. What have they done to the computer? (Что они сделали с компьютером?) Explanation: Here, we use the present perfect tense to ask about actions that have happened in the past but have an impact on the present. The speaker wants to know what has been done to the computer. 8. Where have I left my keys? (Где я оставил свои ключи?) Explanation: Once again, we use the present perfect tense to talk about an action (leaving the keys) that happened in the past but has a connection to the present (the speaker still doesn't know where they are now). 9. Simon has not met Jenny's parents yet. (Саймон еще не встречался с родителями Дженни.) Explanation: Similar to the previous sentences, we use the negative form of the present perfect tense to state that the action of meeting Jenny's parents has not happened yet. The word "yet" implies that it may still happen in the future. 10. We have just sent her an e-mail about our trip to London. (Мы только что отправили ей электронное письмо о нашей поездке в Лондон.) Explanation: Here, we use the present perfect tense to talk about an action (sending the email) that happened in the past but has a connection to the present (it was just sent). The words "just" highlights that the action happened very recently.
