3、示过去确切时间的状语，常用现在完成时；如果有，则只能用一般过去时。如： I have visited the factory. I visited the factory last year.二看句首有无疑问词。如果笼统地问人家做过某事了吗（句首无疑问词），常用现在完成时；但进一步询问何时、何地、何原因、用什么方式做那事时（句首有疑问词）就要用一般过去时。如：Have you had your breakfast? Yes, I have.When did you have it? At seven thirty.注意： 这种用法是以连贯性问答为背景的。否则就需要具体情况具体分析。如： How many words have you learned by heart? How did you learn them by heart?三看句中谓语动词是否为延续性动词。如果表示的动作或状态一直延续到现在，最好选用延续性动词，并使用现在完成时；如果是瞬间动词，则用一般过去时。如： He has been a league member for two months. He joined the Youth League two months ago.专心-专注-专业
