Question

Thank you very much for explaining to me the best choice.
I still have a few sentences I'm doubtful of. I included 7 doubts using question words. Thank you

1) Sometimes my parents aren't at home for (?) their work and so I have to stay at home alone with my brother.
2) I felt sorry for my mum because she has a broken leg (better: she broke her leg, she had a broken leg).
3) I finished primary school with an average mark of 9 out of (?) 10.
4) I was proud of myself on 24th July when I passed my driving test.
5) The teacher reprimanded me (= wrote a reprimand in the class register??)
6) It was the last sad moment in my life when my girlfriend broke up with me (?). While I was climbing a step I fell on the floor (?)(I fell down on the floor)

Answer 1

1) Sometimes my parents are at work, not at home, so I have to stay at home alone with my brother.
<b>?? </b>

2) I felt sorry for my mum because she has a broken leg (better: she broke her leg, she had a broken leg).
<b>I'd say "... because she broke her leg."</b>

3) I finished primary school with an average mark of 9 out of 10.
<b>OK </b>

4) I was proud of myself on 24th July when I passed my driving test.
<b>OK </b>

5) The teacher reprimanded me (= wrote a reprimand in the class register??)
<b>OK, either way you want to write it is fine. </b>

6) It was the last sad moment in my life when my girlfriend broke up with me. While I was climbing a step, I fell down.
<b>If you fall down, "on the floor" is usually assumed -- or "on the field" if you're outdoors, etc.
I don't understand "last sad moment" -- do you mean this? ~~> The last time I felt sad was when my girlfriend broke up with me.</b>
