Hello Amir! :)
"The neighbours were not happy because HER children WAS too noisy."
In this sentence better to say not "her", because it's not so clear, who is this "her", - it's better to repeat the word "aunt". And of course plural verb after "children". So, it should be:
"The neighbours were not happy because AUNT'S children WERE too noisy."
Next you have: "There WASN'T NOTHING in the fridge."
You cannot use double negation in a sentence. So, you should say:
"There WAS NOTHING in the fridge." or "There WASN'T ANYTHING in the fridge." (in this case you use negation only once).
In the next several sentences you have the same mistake:
"There WEREN'T vegetables for dinner, there WASN'T juice for her children." and "There wasn't even bread in the house!"
The rule is we use 'no' before a noun phrase:
e.g. There’s no address on the envelope.
No biscuits before dinner!
So, you should do like in example:
"There WERE NO vegetables for dinner, there WAS NO juice for her children."
"There even WAS NO bread in the house!"
OR! It's also possible to say:
"There WEREN'T ANY vegetables for dinner, there WASN'T ANY juice for her children."
"There even WASN'T ANY bread in the house!" (meaning is the same)
Hope, it was helpful :)
