(3)never意为“从来没有；决不”，表示否定含义，常位于助动词have/has之后，过去分词之前。如：They have never watched a football match. 2. 现在完成时与一般过去时的区别 (1)现在完成时表示过去发生的某一动作对现在造成的影响，强调的是现在的情况；一般过去时表示过去发生的动作或存在的状态，与现在无关。如： ◇I have seen this film.(强调对现在的影响，已经知道了电影的内容) ◇I saw this film yesterday.(强调看的动作发生在过去，与现在无关) (2)现在完成时常与ever，never，just，already，yet，so far，recently，in the past/last few years等连用。一般过去时常与具体的表示过去的时间状语连用，如：yesterday，last year, ... ago，in 1999，just now等。 一、单项填空 (　 　)1.(2023邵阳)—Hello, this is Lily speaking.
