[译] 脸颊上的刀伤毁坏了他的容貌。
[误] The cut across his cheek has spoilt his look.

[正] The cut across his cheek has spoilt his looks.
[注] look 的意思是“表情”，如：I knew she didn’t like it by the look on her face. 我从她脸上表情看出来，她不喜欢它。looks 才是“容貌”的意思，如：You can’t judge a person by his looks. 人不可貌相。looks 有时还可解释为“美貌”（= good looks），如：She is beginning to lose her looks. 她的美貌开始消失。
