Выберите правильное местоимение: 1. His parents want ... to behave well at school, a) him b) he c) his 2. I want ... to pay attention to your grammar, a) your b) you c) yours 3. They expect ... to arrange a party, a) I b) my c) me 4. Our teacher expects ... to think of our future, a) ours b) us c) we 5. Would you like ... to stay out of trouble? a) they b) their c) them

Правильные варианты и почему:

1. His parents want him to behave well at school. — после want ставим объектное местоимение + инфинитив (want someone to do). → a) him

2. I want you to pay attention to your grammar. — та же конструкция: want you to…. Ни your, ни yours не подходят, потому что требуется объект, а не притяжательное. → b) you

3. They expect me to arrange a party. — после expect также объект + инфинитив (expect someone to…). → c) me

4. Our teacher expects us to think of our future. — expects us to…; не we (это подлежащее), не ours (притяжательное местоимение). → b) us

5. Would you like them to stay out of trouble? — после would like используется объект + инфинитив (would like someone to…). → c) them

Итого: 1–a, 2–b, 3–c, 4–b, 5–c.
