　　现在完成时用法解析
　　1.构成     
　　现在完成时是由助动词 have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词，说明句子的意义。
　　2.用法      
　　（1）表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如：       
　　-Have you had lunch yet?     -Yes,I have. I've just had it.       
　　你（已经）吃午饭了吗？ 我刚刚吃过。（现在我不饿了）      
　　（2）表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止，可能仍然在进行。常带有for和since等表示一段时间的状语。              
　　如：He has taught here since 1981             
　　他自1981年就在这儿教书。（可能还要继续教）              
　　I have't seen her for four years.              
　　我有四年没见到她了。       
　　（3）表示说话前发生过一次或多次的动作，现在成为一种经验，一般译为汉语“过”，常带有twice,ever,never,three times等时间状语。
