A句
Theychosethis particular behavior for three reasons, according to study co-author Eric Schwitzgebel, a philosopher at the University of California, Riverside其中，1.for three reasons——介宾结构作原因状语此时，for three reasons位于名词后且位于完整句结尾，便涉及定语or状语的区别——译为定语：他们选择“出于三种原因的”特定行为；译为原因状语：他们选择这种特定行为，出于三种原因：...显然，结合句意，译为状语更加合适，因此该介宾结构作原因状语表示主句发生的原因！2.according to study co-author——介宾结构作状语表示前面信息的来源； 3.Eric Schwitzgebel——名词作co-author的同位语【判断方法：在名词|代词后；2.co-author=Eric Schwitzgebel，即合著者就是Eric Schwitzgebel】
3.a philosopher at the University of California, Riverside——名词短语作Eric Schwitzgebel的同位语【判断方法：1.位置：在名词|代词后；2.Eric Schwitzgebel=a philosopher at the University of California, Riverside，即Eric Schwitzgebel是加州大学河滨分校的一名哲学家】
