1. silver laughter 銀鈴般的笑聲，好直接的翻譯，

2. musical→containing or constituting or characterized by pleasing melody. 強(qiáng)調(diào)韻律感，

3. euphonious→①having a pleasant sound.

②(of speech or dialect) pleasing in sound; not harsh or strident.

4. dulcet→extremely pleasant in a gentle way；pleasing to the ear.

看英英解釋，euphonious、dulcet與mellifluous差別好像不大，

mellifluous正好可以分解各通melli和flow，將甜美和流暢的意思都包含進(jìn)去，
