Sure, let's go through each sentence and provide the correct form of the verbs in the present simple tense:
We eat eggs for breakfast every day. (eat)
- The verb "eat" remains in its base form "eat" because the subject "we" is a plural subject.
Our teacher always gives us homework on Friday. (give)
- Here, the subject "our teacher" is singular, so the verb "give" takes the form "gives."
I'm sorry—I don't know the answer. (not know)
- For the negative form with the subject "I," we use "do not" or "don't" followed by the base form of the verb "know."
My father doesn't like football. (not like)
- Since "my father" is a singular subject, the negative form requires "does not" or "doesn't" followed by the base form "like."
Do all your friends go to the same school? (go)
- In questions with plural subjects like "all your friends," we use "do" followed by the base form of the verb "go."
Where does your best friend live? (live)
- For a singular subject like "your best friend," the question form requires "does" followed by the base form of the verb "live."
Here's a summary of the sentences with the verbs in the correct present simple form:
- We eat eggs for breakfast every day.
- Our teacher always gives us homework on Friday.
- I'm sorry—I don't know the answer.
- My father doesn't like football.
- Do all your friends go to the same school?
- Where does your best friend live?
In the present simple tense, the verb forms change based on the subject (singular or plural), and whether the sentence is positive, negative, or interrogative.
