As you can see,the present perfect tense is formed with the verb to have and the past participle of the main verb,in this case,spoken.
正如你所看到的,过去完成时是由动词have加上实意动词的过去分词形式,比如spoken.
The simple past tense is just the past form of
the verb,which in this case is spoke.
过去时只是由动词的过去式构成,比如spoke.
These tenses are used a bit differently.
时态的使用是有一点区别的.
The present perfect tense expresses an event that happened in the past when the exact time is not known,or when there's a result or a connection being made to the present,or when the time reference is still unfinished,as in so far this week,or up to now,or during my entire life.
现在完成时表示发生在过去的不知道准确时间的事情,或者结果与现在有关联,对现在有影响,或者时间未结束,仍然在延续,例如“直到本周”,“直到现在”,“在我的一生中”这样的时间状语.
The simple past tense,on the other hand,expresses an action that happened when a specific finished time is given,such as yesterday or last
过去式,另一方面表达的是时间已经过去的,特定事件已经结束了的行为,比如“昨天”,“过去”这样的时间状语.
