What an easier way is there for a nurse, a policeman, a barber, or a waiter to __6__ professional identity（身份） than to step out of uniform? Uniforms also have many __7__ benefits. They save on other clothes. They save on laundry bills. They are often more comfortable and more durable than civilian clothes.
　　Primary among the arguments against uniforms is their lack of variety and the consequent loss of __8__ experienced by people who must wear them.

　　A teacher who continually draws attention to rewards or who hands our high grades for __8__ achievement ends uPwith uninspired students, Eisenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and __9__ failing grades. 　　In early grades, the use of so-called token economies, in which students handle challenging problems and receive performance-based points to ward valued rewards, shows __10__ in raising efforts and creativity, the Delaware psychologist claims.
