问题
选择题
The father as well as his three children ____ skating on the frozen river every Sunday afternoon in winter.
A．is going
B．go
C．goes
D．aregoing
答案
C
下划线处与单数形式的主语the father搭配，不受as well as his three children的影响，因此应排除选项B、D。根据状语“every Sunday afternoon in winter”提供的，下划线处应该用一般现在时表示与现在相关的经常性活动，因此应进一步排除A而选出C。
