谁能帮我总结一下初中所学内容中的现在完成时
一． 基本结构：助动词have/has+过去分词(done)
二．　句型：
否定句：主语+have/has+not+过去分词+其他.
一般疑问句：Have/Has+主语+过去分词+其他.
简略答语: Yes, 主语 + have/has.(肯定)
　　　　　　　No, 主语 + haven't/hasn't.(否定)
三．用法
（1）现在完成时表示过去发生或已经完成的动作对现在造成的影响或结果
　　I have spent all of my money (so far).(含义是:现在我没有钱花了.)
　　 Guo zijun has (just/already) come. (含义：郭子君现在在这儿)
My father has gone to work.(含义是:我爸爸现在不在这儿) （2）现在完成时可以用来表示发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示）常与for（+时间段）,since（+时间点或过去时的句子）连用.
　　①for+时段
　　②since+过去一个时间点（译为：自从……以来）
　　③since+时段+ago
　　④since+从句（过去时）
　　●⑤It is+时段+since+从句（过去时）
　　Mary has been ill for three days.
　　I have lived here since 1998.
　四．　has gone (to),has been (to), has been (in) 的区别
　　 Have/Has gone(to) :去了(现在不在说话现场)
Where is your father?He has gone to Shanghai.
Have/Has been (to) :去过（已不在去过的地方）
My father has been to Shanghai.
Have/has been in：呆了多久（还在所呆的地方）
My father has been in Shanghai for two months. /since two months ago.
五．现在完成时的标志　　
　1.　现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义:
　* 以already, just和yet为标志
　　He has already got her help.　他已得到她的帮助.
He has just seen the film.　他刚刚看过这场电影.
He hasn't come back yet.　他还没有回来.
　　* 以ever和never为标志　
This is the best film I have ever seen.　这是我曾经看过的最好的一部电影.
He has never been to Beijing.　他从没有到过北京.
　　* 以动作发生的次数为标志
　　He says he has been to the USA three times. 他说他已经去过美国三次了.
　　* 以so far（到目前为止）为标+before
　He has got to Beijing so far.　到目前为止他已到了北京.
She has passed the examso far.　到目前为止她已经通过了考试.
2.过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手,进一步学习现在完成时.
　* 　①for+时段 ②since+过去一个时间点（过去 从句）为标志
注意： 1)现在完成时不能单独与过去的时间状语连用, 如yesterday,last week, three years ago 等; 2)不能与when连用 2.现在完成时往往同表示不确定的过去时间状语连用
　六．过去分词

　　(2)、以“ e ”结尾的动词,只在词尾加“ d ”.
　　live---lived---lived ,
　　(3)、以“辅音字母 + y ”结尾的动词,将 "y" 变为 "i" ,再加“ ed ”.

参考答案：
一、单项选择.
1、现在完成时主要强调过去发生的动作对现在造成的影响,或过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响.这种考查难度较大,往往无时间状语,需要从上下文分析、推理才行.故上两侧根据上下文分析、推理,正确答案是B.
2、现在完成时常与already（已经）,just（刚刚,正好）,ever（曾经）,never（从来,也不；从不）,before（以前）,yet（仍然）等连用.故2应选B.
3、C
4、现在完成时常与recently（近来）,so far（到目前为止）,in the past/“last + 一段时间”等时间状语连用.因为上述短语表示的是从现在起往前推算的一段时间,句中的动作是从过去某一时间或时刻开始持续到现在的.故4应选D.
5、C
6、现在完成时时常与“for +时间段或since +过去时间点”连用（含从句,从句过去时）.故6应选C.
7、C
8、现在完成时还与once（一次）,twice（两次）,three times（三次）,several times（几次）等表示重复次数的词语连用.故8应选B.
9、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9的正确答案为B.
10、B
11、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语连用,通常是用相应的延续性动词来代替.故11的正确答案依次为：D.
12、B 13、A 14、C 15、A.
16、“have/has gone to + 地点”表示“某人去了某地（还未回来）”,指主语所指的人不在这儿.“have/has been in + 地点”表示“在某地呆了多长时间”,常与表示时间的状语连用.“have/has been to +地点”表示“曾经去过某地（但现在已不在那儿）.”故16的正确答案为A.
17、A 18、D 19、C 20、C
二、句型转换.
1、has he? 2、How long 3、died, has been dead
4、has been open 5、has been away 6、joined；ago
7、It is, since 8、The bus has been here for ten minutes.
三、汉译英.
1、Jim has finished doing his homework already. He is free now.
2、He received a letter yesterday.
3、My father has been to the Great Wall before.
4、She hasn't seen the new film yet.
5、She has been to Shanghai.
