Could you correct my English sentence?

On a scale of 1 to 10, how good is my English?
(pls let me know separately for each①②③)

①Such fire must hurt people who have tried to get over the damage of war.

②Whether cultural things or rebuilt ones, what we have to be the most carefully to protect such buildings made by wood is fire.

③Losing historical buildings by war or fire are as if we lost our past.

See a translation

① 9/10
You have to add 'have' after 'must'.

"Such fire must have hurt the people who tried to get over the loss of war"

If you don't use 'have', it feels like you're ordering the fire to hurt the people..


② 7/10
"Whether it be cultural things or rubuilt ones, what we have to be most careful to protect are buildings prone to burning, such as ones made by wood"
(Prone = 傾く)

I still understood what you were trying to say perfectly, so good job!


③ 9.8/10
You just mistook 'are' for 'is' which is a minor mistake.

"Losing historicals buildings to war or fire is as if we lost our past"

Overall, 26.8/30! Great!! よくできました♥️
