1、-和现在完成时连用的时间状语-第 3 页和现在完成时连用的时间状语现在完成时是一个与过去和现在都有关系的时态,因此,具有这样时间特点的状语都可以与现在完成时连用。 1. 与表示一段时间的状语连用,如for+时间段,since+时间点。如:We have lived in this city for more than 40 years. 我们在这个城市已生活了40多年。We have lived in this city since 1958. 我们从1958年起就住在这个城市里。从以上两个例句我们可以看出,与表示一段时间的状语连用时,谓语动词常为stay, live, teach, lear

5、y bag? 你看到我的手提包了吗? (你知道它在哪里? )注意:1. 现在完成时不与yesterday, last week, two days ago, in1983, just now, when等表示具体的过去时间的状语连用。2. 一般过去时只强调在过去发生过某事或关注的是动作发生的时间、地点、方式等;而现在完成时则强调过去的动作对现在的影响,因此,若现在影响并不存在时就不能用现在完成时了。如说I have closed the door. 那门现在也是关着的,若被风吹开了,就只能说I closed the door. 了。表示从过去某一时刻开始一直持续到现在的动作或状态。常与“sin
