现在完成时(2)
一、概述
1. 现在完成时的标志词:当表示动作已经完成并对现在有一定影响时,我们一般用现在完成时。同时,可分别用just, already或yet加以强调或说明。如:
2.考点介绍:just, already与yet的区别
I have already heard the news. 我早已听到消息。
I haven’t heard the news yet. 我还没听到消息。
I have just heard the news. 我刚听到消息。
二、一般过去时与现在完成时的区别
1. 一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调的是过去的动作。如:
I visited West Lake in 2012. 我在2012年游览过西湖。(强调过去参观西湖这一事实)
2. 现在完成时表示过去发生的动作对现在造成的影响或结果,强调的是过去的事情对现在仍有影响。如:
I have visited West Lake, so I won’t go this time. 我游览过西湖,所以这次我不去了。(强调对现在造成的影响)
【注意】当没有明确的过去时间状语时,判断使用现在完成时还是一般过去时的标准是看该行为是否对现在有影响,即该句想要强调什么。
