英文白痴 作文求評 urgent help!!!!!!!!!

1你英文叻過大把人,睇得出你自己寫,係冠詞(articles,a/an/the用得差):
On behalf of all students(冇指定唔使同the)
quality of food provided(少尐動詞,簡潔尐,意思/文法都啱)
holding assembly and sport events前後唔對稱,你用designated做主要動詞,後面加個act,會唔明你講乜
2 tone唔用簡寫,用多尐strongly believe,都ok,但你開頭個連詞/not only,but also用得幾好
3內容充實唔夾硬,都全面,我諗唔到其他
4principal後面都要隔行,各方面都冇乜問題...
希望有更多人幫你,加油
