现在完成时表示一个动作或状态从过去某一时刻开始一直持续到现在，并有可能持续下去。可以和表示一段时间的状语连用，如“for+时间段”“since+过去的时间点或从句”或“since+一段时间+ago”。Ilivedherein2010.Istillliveherenow.Ihavelivedherefor12years.2010nowIhavelivedherefortwelveyears.=Ihavelivedheresince2010.延续性动词拓展延续性动词和非延续性动词的用法1.含义：延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。非延续性动词也叫终止性动词、瞬间动词等，表示不能延续的动作，这种动作发生后即刻停止。2.用法：①常见的延续性动词有learn,work,live,know,walk,watch,sleep,stay,wait,keep等。延续性动词可以用在现在完成时中与表示一段时间的状语连用，如howlong，for＋时间段，since＋过去的时间点，since引导的时间状语从句(一般过去时)，since＋一段时间＋ago等。②常见的非延续性动词有open,close,die,begin,come,go,borrow,lend,buy,move等，可以用

于现在完成时，说明某个动作的结果还存在，

但不能与表示一段时间的状语连用。③在否定句中，非延续性动词可以与表示一段时

间的状语连用。例：我已经有三个星期没有收到我朋友的来信了。Ihaven’theardfrommyfriendforthreeweeks.3.非延续性动词（短语）与延续性动词（短语）
