groom eyebrows 和 trim eyebrows 的差別在哪裡？如果不好說明，請提供一些例句。

Trim means to cut. Trimming eyebrows means to cut hair or perhaps to remove hair.
Grooming is the process of taking care of yourself: hygiene and appearance.

Grooming your eyebrows almost certainly means to trim your eyebrows, because there is nothing else to do with eyebrows. It is implied.

Grooming hair could mean to comb, to put in a scrunchy, or to trim the hair.
