要赞美别人的美丽有哪些英文的表达法？有什么区别呢？

You're so beautiful/pretty/handsome/cute/charming!
前两个只能形容女性，第三、四个形容男性，第五个一般形容男性。它们的一般意思依次是：美丽，漂亮，英俊，可爱，迷人。说女生可以说“She's a dish!"or "What a dish!"，这是习语。还有一个词comely，意为“标致的，秀丽的；（举止等）合宜的，恰当的”。
very 是“非常”：你真漂亮！你非常漂亮！so是“你这么漂亮！”用这两个词语气会更强烈一些。

You are so beautiful.很美丽
You are very pretty. 美丽
You are very lovely. 可爱
You are so cute. 可爱

You are gorgeous. 你美丽极了
