Answer 1

Do,Don't,Have последовательно

Answer 2

It seems like your sentences are incomplete, but I'll do my best to help you understand the correct usage of "do/does" and "have to/has to."

1. Do/Does: "Do" is used with the pronouns: I, you, we, and they. Example: "I do my homework every day." "Does" is used with the pronouns: he, she, it, and singular nouns. Example: "She does her homework in the evening."

2. Have to/Has to: "Have to" is used with the pronouns: I, you, we, and they. Example: "I have to finish my homework." "Has to" is used with the pronouns: he, she, it, and singular nouns. Example: "She has to submit her report."

Now, let's complete your sentences:

7. Do you have to do a lot of homework at the weekend? (Correct)

8. Sarah and Peter have to come home before (what time? You need to complete the sentence to make it grammatically correct.)

Example: "Sarah and Peter have to come home before 10 PM."

Remember, the correct usage of "do/does" and "have to/has to" depends on the subject (who is performing the action) and whether it is singular or plural.
