Answer 1

The sentences should be completed using either the future perfect tense or the future perfect continuous tense, depending on whether the emphasis is on the completion of the action or its duration up to a certain point in the future.

Step-by-step explanation:

The correct form of the future perfect or future perfect continuous tense should be used to complete the sentences. These tenses are used to describe actions that will be completed by a certain point in the future or that will continue up to that point.

1. By 9 o'clock, he will have finished his homework.
2. They will have left the classroom by the end of the hour.
3. By the end of the month, I will have been living in this town for ten years.
4. By the end of this week, we will have been working on the project for a month.
5. By July the fifth, they will have been studying English for 3 years.
6. By 10 o'clock she will have been watching TV for 4 hours.
7. She will have been sleeping for 10 hours by 11 o'clock.
8. We will have been looking for him for 40 days by next Saturday.
9. He will have written a book by the end of the year.
10. She will have returned from the excursion by 6 o'clock.

Remember, the future perfect tense (will have + past participle) indicates that an action will be completed before a specific time in the future, while the future perfect continuous tense (will have been + present participle) emphasizes the duration of an action continuing up to a certain time.
