说话人强调的是该动作或状态对现在的结果或影响。

My daughter has just gone out. 我女儿刚出去。

I’m sure we’ve met before. 我肯定我们以前见过面。

2)表示持续到现在的动作或状态,往往和包括现在在内的表示一段时间的状语连用,如recently, already, just, lately, for…,since…,yet等。

英语人教版八年级下册九年级英语现在完成时态语法复习讲解及练习(含答案)

现在完成时态的讲解及专项练习现在完成时是初二要学到的语法内容,也是中考的重点和难点。

一. 现在完成时基本结构①肯定句:主语+have/has+动词的过去分词②否定句:主语+have/has+not+动词的过去分词③一般疑问句:Have/Has+主语+动词的过去分词④特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词)二. 现在完成时用法1. 现在完成时用来表示过去已经完成的动作对现在造成影响或后果。

也就是说,动作或状态发生在过去但它的影响现在还存在,强调的是现在。

I have already posted the photo.我已经邮寄出了照片。

与此种用法连用的时间状语时一些模糊的过去时间状语,如already(肯定句句中), yet (否定句/疑问句句尾), just, before, recently,still, lately,never等。

2. 现在完成时也可用来表示动作或状态发生在过去某一时刻,持续到现在并且有可能会继续持续下去。

He has lived here since 1996自从1996年以来,他一直住在这儿。

(动作起始于1996年,一直住到现在,可能还要继续住下去。

)此种用法常与for(+时间段),since(+时间点或过去时的句子)连用。

谓语动词必须是延续性动词。

有些瞬间动词可变为延续动词:go out----be outfinish----be overopen----be opendie----be deadbuy---havefall ill---be illcome back----be backcatch a cold----have a cold三. 现在完成时常见考点对于现在完成时的考查,多以单选、句型转换或词语运用的形式考查学生在具体语境中灵活运用时态的能力。

在考试中,会让大家判断是否该用现在完成时,或者是考查“瞬间动词”不能与表示一段时间的状语连用”这一知识点。
