()---you didn't catch the train,did you?---------,i tried my

A.No,I didn't
下文i tried my best to get there on time.看不出成功的结果
如果是最终赶上了,应该有 and I managed to .,而不是强调过程的tried
再问： 我们英语老师说选A,可是我不能理解...我觉得他是赶上了呀
再答： i tried my best to get there on time 我尽最大努力准时赶到那（不一定如愿）。
try(do) one's best to do sth 强调的不是结果， 是动作本身！！
