Americans are proud of their variety and individuality (个性), yet they love and respect few things more than a uniform, whether it is the uniform of a lift operator or the uniform of a five-star general. Why are uniforms so popular in the United States Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian (百姓的) clothes. People have become conditioned to expect higher quality from a man who wears a uniform. The television repairman who wears a uniform is likely to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a hairdresser, or a waiter to lose professional identity (职业身份) than to step out of uniform
Uniforms also have many practical good points. They are often more comfortable and more lasting than civilian clothes. Primary among the argument against uniforms is t
A. are usually helpful
B. bare little freedom
C. lose personal character
D. enjoy greater popularity
