Задание F

Ответ:

1. Sometimes my father buys magazines in this news-stall.
2. The students usually answer the questions very well.
3. Her daughter rarely helps her.
4. Every day they watch TV.
5. As a rule, his grandfather reads newspapers in the evening.

Принцип: здесь используется Present Simple, потому что речь идёт о регулярных действиях. На это указывают слова sometimes, usually, rarely, every day, as a rule.

• Если подлежащее можно заменить на he / she / it, к глаголу добавляем -s:
  father buys, daughter helps, grandfather reads.
• После I / you / we / they и существительных во множественном числе глагол остаётся без окончания:
  students answer, they watch.

Проверка:

• my father → he → buys;
• the students → they → answer;
• her daughter → she → helps;
• they → watch;
• his grandfather → he → reads.
