请大家看上面的几组句子，每一组句子中，前一句是一般过去时的句子，过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；后一句是现在完成时的句子，表示过去发生或已完成的某个动作对现在产生的影响或结果，强调的是过去的事情对现在的影响或结果。
用下划线画出现在完成时的结构。（肯定式，否定式，疑问式）
We have seen the film. Have yu seen the film? N, we haven’t. We haven’t seen the film.
I have finished the hmewrk. Have yu finished the hmewrk? N, I haven’t. I haven’t finished my wrk.
I have already arrived. Have yu arrived yet? N, I haven’t. I haven’t arrived yet.
She has just washed the clthes. Has she washed the clthes yet? N, she hasn’t. She hasn’t washed her clthes yet.
I have ever read this bk. Have yu read this bk? N, I haven’t.I have never read this bk.
表示过去发生或已完成的某个动作对现在产生的影响或结果，同already, just, yet等状语连用。例：
I have just turned ff the light. 我刚刚把灯关上。(结果是灯已经关上了) I have already read the bk. 我已读过这本书了。(结果是已知道这本书的内容) He hasn’t fund his eraser yet. 他还没有找到橡皮。
注意：副词 just 常用于肯定句中，放在have / has后；而already多用于肯定句中，可放在句中也可放在句末表示强调；yet 一般用于疑问和否定句中，译为：“还、仍然、或已经”。
Have yu finished yur hmewrk yet? 你还没有完成作业吗？
● have been t和have gne t的区别：have been t 强调“去过”，现已不在那里，如：He has been t the USA three times.他(曾经)到美国去过三次。(他人生中有过这样的经历，过去“到过美国”，现在已“不在美国了”)He has gne t the USA. 他已经去美国了。(主要强调的是“去了”，也许刚动身出发，也许已经到了，也许还在路上，总之现在人不在说话的现场。)
● have been t 和have been in的区别 have been t强调人“已回到原地”，后面可接表示“次数”的状语。例： She has been t Shanghai nly nce. 她只去过一次上海。— Hw many times has he been t Shanghai? 他去过几次上海？ — He's been there many times. 他去过很多次。
have been in表示某人“已在某地停留一段时间，现仍在那里”，其后常带表示一段时间的状语。例：They have been at the barber’s shp fr half an hur. 他们在理发店呆了半小时。(现在仍然在理发店)We have been in Xi'an fr tw weeks. 我们在西安呆了两个多星期。(现仍在西安) Hw lng have they been in China? 他们在中国呆了多长时间了？(仍在中国)
● 现在完成时态中可以和表示一段时间状语(fr, since, hw lng, all ne’s life)连用的动词必须是表示延续的情况或动作的动词，即延续性动词，常与since, fr等连用。She has taught in the schl fr ten years. 她在这所学校教书已经10年了。 I haven't eaten anything since breakfast. 我从早饭起就一直没有吃东西。 I have knwn her since we were children. 我从小就认识她。 注意：since与时间点相连，而fr与时间段相连。
