类型是type，亚种是subtype，种族是race。
RACIAL EMULATION
[RACIAL]
You can emulate a humanoid
more closely with your minor
change shape ability.
Prerequisite: Changeling.
Benefit: When you use your
minor change shape ability to
assume the form of a humanoid
creature, you can also emulate any
of that humanoid’s subtypes.
Though you do not gain any of
the humanoid’s traits, you are
considered to be a member of that
race for all other purposes (allowing you to
use magic items or spells keyed to race, for example).
You can also ignore the normal penalty on Disguise
checks when disguising yourself as a different race
(see the Disguise skill description, page 72 of the
Player’s Handbook).
You can only emulate one race at a time, and you
always retain the shapechanger subtype.
模仿的是类人生物亚种。也就是人类亚种，精灵亚种这样的。
