问题补充：
The pretty girl is always busy helping her mother with the housework I go to visit her family.
A. every time
B. every time when
C. at every time
D. however time
答案：
(答案→)A. every time
B. every time when
C. at every time
D. however time
解析：考察连词。Every time 每次干某事的时候，引导时间状语从句，B when多余，C只能作时间状语，不能引导从句，D 无此用法
句意为，每次我去她家，那个小女孩总是忙着帮助她的妈妈做家务，
