Tom's father,as well as his mother,( )in New York for a few more days.a:ask him to stayb:asks he stays c:ask he stay d:asks he stay

b:asks he stays 正确是 asks him to stay

d
简单一点说，as well as 后的不要看，只看前（tom's father）
ask him to stay ,-----ask sb to do sth
ask him that he should say-----虚拟语气

D
主语是 Tom's father (注意不是 his mother), 故后接单三形式, 排除 A C
这里有两种说法：
1.用复合宾语 asks him to stay (b 的宾语 he 形式有误）
2. 接宾语从句 ask（that ) he (should) stay
ask 后接从句时 用should 加动词原形, should 可省, 这是虚拟语气
