I urgently need you to check the following sentences. Thank you,Writeacher.

1) They left to go back home.
2) They always sulk about having to do too much homework.
3) He's having a sulk about ... (could you help me complete this sentence?)
4) Peter and Mary are looking for a house. At the moment they are living (also they live?? Both possible?) with their parents.
5) I've go wide apart green eyes (or wide apart and green eyes?)
I make friends with everybody (??)
I have little lunch and then I start my homework.
6) In my family there are three of us: my mum, my dad, and I.
I'm curious and distract (but sometimes absent-minded/inattentive in class)
7) I arrive at home (I arrive home is a mistake?) only at two o'clock because I live far from school.
8)I leave Turin at eight (I live from Turin at eight)

3) He's sulking about not being allowed to go to the movies.

4) Peter and Mary are looking for a house. At the moment they are living (also they live?? Both possible?) with his parents. Yes, both are possible. However, I'm sure they don't live with all 4 parents!!

5) I have wide-set, green eyes.

I make friends with everybody.

I have a little lunch, and then I start my homework.

6) In my family there are three of us: my mum, my dad, and I.

I'm curious and often distracted in class.

7) I arrive home at two o'clock because I live far from school.

8)I leave Turin at eight.

1) The sentence "They left to go back home" is grammatically correct.

2) The sentence "They always sulk about having to do too much homework" is grammatically correct.
3) To complete the sentence "He's having a sulk about..." you need to provide the specific thing or situation he is sulking about. For example, "He's having a sulk about not getting the promotion he wanted" or "He's having a sulk about his favorite team losing the game."
4) Both "They are living with their parents" and "They live with their parents" are grammatically correct. You can use either depending on whether you want to emphasize the continuous nature of their living situation or simply state the fact.
5) The correct phrase should be "I have wide apart green eyes." The words "wide apart" describe the distance between your eyes, so they should be connected to "eyes" with no comma.
The sentence "I make friends with everybody" is grammatically correct.
The sentence "I have little lunch and then I start my homework" would be better as "I have a small lunch and then I start my homework."
6) The sentence "In my family there are three of us: my mum, my dad, and I" is grammatically correct.
Instead of "I'm curious and distract," it would be more accurate to say "I'm curious and easily distracted in class."
7) Both "I arrive at home" and "I arrive home" are grammatically correct. However, "I arrive home" is more commonly used.
8) Instead of "I live from Turin at eight," it would be better to say "I leave Turin at eight." This sentence indicates that you are departing from Turin at eight o'clock.
