唔該可唔可以幫我check grammar?

1.Have you ever imagined that you will be a princess one day? If you have, you should watch this film.

建議 : 第一句結構有問題, have you ever 是 present perfect tense , 但 "will be"是future tense ...
可改成 : have you ever imagined that you're a princess ?
[ 因為princess唔會係後天,是一生出黎就會係...所以都唔會will be ]
(純粹我個人見解咋,不必一定arm)

2.This is a cool, comical Cinderella story that will touch your heart.
建議: 我覺得 that touch your heart就ok了,可以delete"will"字
另外,我覺得你用cool黎形容cinderella story 不太合適, 可以用romantic

3.建議改成 : One day, she discovered an astonishing news that she is a real princess. (discover:發現 , 這裡應該用"an"適合過"the", real-life是指現實的, 如果你想說"真正的公主",用"real"就可以了

4.The reluctant princess must make the biggest decision of her life, whether to choose with her family or to leave everything behind to accept the royal responsibilities that come with being the Princess.

可改成 : The fidgety princess must make the biggest decision of her life, whether choose with her family or leave everything behind to accept the royal responsibilities of princess.

建議: 1) reluctant=不情願的;勉強的 如果你想表達"不知如何是好" 的話 ,可以用"fidgety"
2) whether 之後唔可以跟to
3) 句子太累贅
4) princess 細階p
