Пример:
Теперь ты должен написать, что каждый школьник сделал (скажите про этих школьников, используя "have" и "finish" или "not finish"):

1) John and Jane _____ their homework.
2) Tim _____ the dishes, but he _____ the garbage yet.
3) Lisa _____ her breakfast, but she _____ her teeth yet.

Совет:
To better understand the distinction between completed and unfinished actions, pay attention to the usage of "have" and "has" with past participles (e.g. completed, listened, stored, etc.). Also, consider the time markers (e.g. since September, yesterday) that indicate when the actions or events took place.
