we wear school uniform at school。 uniform为什么不加s?
uniform指制服,是个可数名词,但有时却是不可数名词,例如in
uniform就是不可数的,‘他穿着校服’是He
is
in
school
uniform,‘他们穿着校服’同样是They
are
in
school
uniform。
而wear
uniform则可不可数都可以,你可说They
wear
uniforms,也可说They
wear
uniform。一般而言,uniform是可数的,例如:He
is
wearing
a
new
school
uniform,
which
sits
badly
on
him(他穿的新校服并不合身)。
