如今完成时态
详细讲解及其练习
一、如今完成时由“have/has+过去分词〞构成，主要有两 个含义： ①表示过去发生的动作对如今呵斥的影响和结果，常用 的时间状语有many times，just，yet，ever，never， just，already，so far, by now等。
I have already watcቤተ መጻሕፍቲ ባይዱed the TV play. 我曾经看过这部电视 剧了。〔如今我对它不感兴趣了〕
He has been to .他去过北京〔曾经回来了〕 He has gone to . 他去北京了。 〔还没有回来〕 have/has been in 待在某地 如：They have been in .他们呆在北京。 〔2〕终止性动词如今完成时的否认式，已变成一种可以延续
的形状，因此可以和表示一段时间的状语连 用。 如： I haven't left here since 2019.自从 2019 年以来，我不断没
有分开过这儿。
