现在完成时讲解及练习（答案）
现在完成时讲解及练习（答案）初中英语主要时态系列(六)——现在完成时讲解及练习1现在完成时的基本结构肯定句：主语+have/has+动词的过去分词+其他否定句：主语+have/has+not+动词的过去分词+其他⼀般疑问句：Have/Has+主语+动词的过去分词+其他特殊疑问句：特殊疑问词+⼀般疑问句（have/has+主语+过去分词+其他）2现在完成时的⽤法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 1978.⾃从1978年以来，他⼀直住在这⼉。
(动作起始于1978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 out finish----be over open----be open die----be dead buy---have fall ill---be ill come back----be back catch a cold----have a cold3现在完成时常见考法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。
