八年级英语期中复习重难点提优训练知识梳理对于现在完成时，我们要重点掌握以下几点：现在完成时的含义（1） 过去发生的动作对现在有影响；（2） 过去发生的动作持续到现在。：现在完成时的标志词already, recent(ly), so far, up to now, yet, till now,since+过去时间点, for+时间段等。：have been in, have been to,have gone to三者的区别（1）have been in 表示呆在某地多久；通常会和how long, since+过去时间点, for+一段时间连用；（2）have been to 表示去过某地已回通常会和次数或ever, never连用；（3）have gone to 表示去过某地还未回，通常有语境 “where is .?”：现在完成时中短暂性动词和延续性动词的转化如果碰到how long, since+过去时间点, for+时间段, 则要将短暂性动词转化为延续性动词如go/come/arrivebe in; leavebe away; buyhave; borrowkeep等。：现在完成时与一般过去时的区别注意，使用现在完成时，一定要满足上面定义中的任何一个，对现在有影响或动作持续到现在，否则发生在过去的动作就用一般过去时。巩固训练一、 单项选择1.
