（1）表示过去发生或完成的某一动作对现在造成的影响或结果。 例：①Have yu read that stry？（你读过那个故事吗?） “读”这一动作发生在过去，对现在造成的影响是：是否知道故事的内容。 ②l have bught tw apples.（我买了两个苹果。）“买”这一动作发生在过去，对现在造成的结果是：拥有两个苹果。
（2）表示从过去的某一时间开始，一直持续到现在的动作或状态。使用的时间状语表示时间段，通常由fr或since引导。
a）fr后常跟一个时间段，表示某个动作到现在为止已持续了多长时间，如：fr three years、fr half an hur等。
b）since作介词，后面可以接一个时间点，也可以接“一段时间＋ag”，如：since 1980、since three years ag、since tw mnths ag等。
c）since还可做连词，引导一个一般过去时的时间状语从句。例：We have knwn each ther since we went t cllege.（自从上大学以来，我们就彼此认识。）
选用fr和since填空1.We haven't seen each ther a lng father has been in the party 10 years film has been n 20 has wrked here he came t grandparents have been dead several ’s five years we met last time.
对现在完成时的时间状语提问通常用Hw lng。eg. Hw lng have yu lived in Beijing? （你在北京住了多久了？） Hw lng have yu studied English？ （你学习英语多久了？）
现在完成时的判定（标志词）
标志词组s far 迄今为止 in the past/last few years在过去的几年里
already: 常用于肯定句中. yet: 常用于否定句,疑问句句尾.
注意点：have been in, have been t 与have gne t 的用法1、have (has) been in 表示“在某地（多长时间）”，现在仍在那里。常与表示一段时间的状语连用。例如：Mr. Brwn has been in Shanghai fr three days. 布朗来上海已经有三天了。2、have( has)been t表示“曾经去过某地”，现在已经不在那里了。可与just, ever, never等连用，例如：Mary has never been t the Great Wall. 玛丽从未去过长城。3、have (has) gne t 意为“到某地去了”，表示到了某地或正在去某地的途中。总之，说话时该人不在现场，例如：----Where is Tm? ----He has gne t the bkshp. 他到书店去了。
现在完成时与一般过去时的用法比较一.一般过去时表示过去发生的动作或单纯叙述过去的事情，强调动作发生在过去，和现在没有关系，而现在完成时是表过去发生的某一动作对现在造成的影响或结果，强调是现在的情况。
二.一般过去时常与具体的时间状语连用。1.一般过去时的时间状语有：yesterday，last week...，一段时间＋ag，in 1980（过去时间），in Octber，just nw，a mment ag等等.
