This dictionary cost you ten dollars,急等
This dictionary cost you ten dollars,
A does it
B is it
C doesn' t it
D didn' t it

This dictionary cost you ten dollars,急等 This dictionary cost you ten dollars,A does it B is it C doesn' t it D didn' t it
D
首先反义疑问句前肯后否,所以C和D又可能
而DICTIONARY是单数,如果是一般现在时COST+S
所以确定是过去式·(COST三型一致)
故选D

选D吧,This dictionary 后面的cost没加s说明应该是过去时,选项中过去时的只有D。
