1. b) I don't smoke. (We use the auxiliary verb 'do not' / 'don't' to form the negative in Present Simple). Перевод: 1. b) Я не курю. 2. a) He drinks a lot of coffee. (In the third person singular, we add -s to the verb in Present Simple). Перевод: 2. a) Он пьет много кофе. 3. a) My cousin has a flat in Paris. (The verb 'have' in the third person singular becomes 'has'). Перевод: 3. a) У моего кузена/кузины есть квартира в Париже. 4. b) Do you live with your parents? (We use 'Do' to form questions in Present Simple with 'you'). Перевод: 4. b) Ты живешь со своими родителями? 5. a) Does your sister have children? (We use 'Does' for the third person singular in questions). Перевод: 5. a) У твоей сестры есть дети? 6. a) Where does your wife work? (In wh-questions, the auxiliary verb 'does' comes before the subject). Перевод: 6. a) Где работает твоя жена? 7. a) 'Do you play the guitar?' 'Yes, I do.' (We use the auxiliary 'do' in short answers for questions with 'do'). Перевод: 7. a) «Ты играешь на гитаре?» «Да». 8. a) I'm an engineer. (We use the indefinite article 'an' before professions).

Перевод: 9. a) Билл — муж Карлы. 10. a) This is my parents's house. (Although 'parents'' is also grammatically correct in many contexts, 'parents's' is sometimes used, but option 'a' implies specific possession here. Let's look closer: actually, standard English usually prefers 'parents'' for plural possessive. However, in tests, if 'parents's' is listed, it is often considered correct as an explicit possessive marker. Actually, b) 'This is my parents' house' is strictly standard grammar. Let's re-evaluate: 'parents' is plural, so the possessive is 'parents''. Option b is the most standard correct form). Перевод: 10. b) Это дом моих родителей.
