What does Betty have to do? Read and complete

Краткий ответ:

1. Betty has to wash the dishes.
2. Betty has to clean the room.
3. Betty doesn't have to wash the dog.
4. Betty has to do her homework.

Как понять:

• ✓ = это делать нужно → has to
• ✗ = это делать не нужно → doesn't have to
• Betty = she, поэтому используем has to, а не have to.
• После has to / doesn't have to глагол ставится в начальной форме: wash, clean, do.

Проверка: пример с ✗ — Betty doesn't have to water the flowers, значит, с ✓ ставим has to, а с ✗ — doesn't have to.
