my friend -------to visit me last saturdayA comesB cameC will comeD has comeD为什么不对
my friend -------to visit me last saturday
A comes
B came
C will come
D has come
D为什么不对

my friend -------to visit me last saturdayA comesB cameC will comeD has comeD为什么不对
B came
因为后面有【过去时间状语】last saturday,所以是B came
这里就表示【他上个星期来看我】,不需要【完成时】,没有造成对现在的影响;

B came 因为是上个星期6,所以用过去式
D为现在完成时,表示过去发生的事情对现在的影响。貌似本句没有味道
