根本差不遠,但beautiful是一種普通的說法,意思跟「漂亮」一樣。但是gorgeous 不常用的,所以,假如說gorgeous的話,就表示「非常漂亮」的意思。 (你們應該有很多說法,可能「華麗」,「絢麗」,「優美」等)
If you call someone 'beautiful' it just means they are pretty, if you say they are 'gorgeous' it means they are extremely pretty, it's much stronger. Usually used for women, but occasionally may be used for a very attractive looking man.
Could also be used to describe nature - "The mountains are gorgeous, aren't they?"
