１.“完成法”：表示过去发生或已经完成的某一动作对现在造成的影响或结果。 ２.“未完成法”：表示动作或状态从过去已经开始，持续到现在并有可能延续到将来。 ⑴already，just，ever，never，before，yet等连用。 ⑵recently，so far，in the past/“last + 一段时间”等时间状语连用。 ⑶“for +时间段或since +过去时间点”连用（含从句，从句过去时）。 ⑷与once，twice，three times（三次），several times（几次）等表示重复次数的词语连用。 四、中考考点： 考点一：考查基本概念 例如： Both his parents look sad . Maybe they ____whats happened to him . 　　Ａ. knew 　　Ｂ. have known 　　Ｃ. must know Ｄ.will know 考点二：考查时间状语 例1. He has _______ been to Shanghai ,  has he ? Ａ. already Ｂ.never  Ｃ.ever Ｄ. still 例2. Have you met Mr Li ______？ Ａ. just Ｂ. ago  Ｃ.before Ｄ. a moment ago 例3. The famous writer ____ one new book  in the past two year . Ａ. is writing Ｂ.was writing  Ｃ.wrote Ｄ.has written 　 考点三：考查与一般过去时的区别 例1.—These farmers have been to the United States .　　—Really ? When ___ there ? Ａ. will they go 　　　Ｂ. did they go 　 Ｃ. do they go 　　　　Ｄ. have they gone  例2.—______ you ___ your homework yet ? —Yes . I _____ it a moment ago .  Ａ. Did ; do ; finished 　 　B.Have ; done ; finished Ｃ. Have ; done ; have finished 　 Ｄ. will ; do ; finish 　　简析：现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday , last week , a moment ago等）连用。故例１、２的正确答案皆为B。 考点四：考查非延续性动词的用法 例1. His father ______ the Party since 1978 . Ａ. joined Ｂ. has joined  Ｃ. was in Ｄ. has been in 例2.—Do you know him well ?  — Sure .We _________ friends since ten years  ago . Ａ. were Ｂ. have been  Ｃ. have become Ｄ. have made 例3.—How long have you ____ here ?  —About two months . Ａ. been Ｂ. gone  Ｃ. come Ｄ. arrived 简析：现在完成时中，非延续性动词不能与for和since引导的表示一段时间的状
