爱华网现在完成时
建议：找点空闲，找点时间，拿出英语，仔细看看，不玩游戏，不迷彩电，no falling inlove ，with a good began
第一部分 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,也可表示过去已经开始,一直延续到现在的动作或状态。 构成:主语+ have/has + 过去分词 +其他。(当主语是第三人称单数时用has,其余人称用have。过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆。)
否定式:主语 + haven't/hasn't + 过去分词 + 其他。
疑问式: 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)
第二部分 现在完成时以already, just和yet为标志
already, just和yet 表示到现在为止动作或状态已经、刚刚或还没有发生。
He has already got her help. 他已得到她的帮助。He has justseen 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
ever和never 表示到现在为止动作或状态曾经或从来没有发生过。
This is the best film I have everseen. 这是我曾经看过的最好的一部电影。He has never been to Beijing.
* 以动作发生的次数为标志
若某一动作到现在为止已经发生了若干次,则要使用现在完成时。
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为标志so far往往表示到目前为止动作或状态已经发生。
He has got to Beijing so far. 到目前为止他已到了北京。She haspassed the examso far.
第三部分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。
英语中的动词从词义上可以分为延续性和非延续性两种,在现在完成时态中一定要注意动词这一特性,应将这类非延续性动词转换为延续性动词。如:
“The play cat” has been on for half anhour. 《猫》已经开演半个小时了。
How long have you had this dictionary? 这本字典你买了多久了?
* 时间“点”、“段”须分清
过去开始的动作可以延续到某一点结束,也可能继续延续,这时就要根据时间“点”、“段”选择相应的介词for或since。如:
He has been away for twoyears. 他已走了两年。(for+时间段)
He has been an English teacher since 1992. 自从1992年以来他一直当英语教师。
(since+过去某一时刻)
第四部分一、She has forgottenher name. She has amnesia.
她已经忘记了自己的名字。她有健忘症。
I have already drunk the coffee
二、当have被用在现在完成时态中时，它可以和前面的代名词一起组成缩写形式。
I've been to New York once before.我曾经到过纽约。
三、现在完成时用not来表达否定形式。She hasn't spoken to him.提问的时候，have需要被提到句首。
Have you seen Matthew?
第五部分 现在完成时和一般过去时的区别
一、一般过去时常常与过去的过去某具体时间搭配使用。如：I went home at 10:00 yesterday.I havegot home now.
二、现在完成时--ever和never。ever表示“曾经”，never表示“从不”；notever=never。ever多用于疑问句，never一般用于否定句；例句：Have you ever been toJapan?（你去过日本吗？）I have never been to Japan.（我从未去过日本。）
