19、n，leave，put，reach，receive，shut，start，stop等。终止性动词用在现在完成时要注意下面三点：1.终止性动词可直接用来表示某一动作的完成。例如：They have reached Shanghai他们已经到达了上海。Has he gone to London?他已经到伦敦去了吗?2.终止性动词表示的动作极其短暂，不能持续，所以，在现在完成时中一般不能和以since，for等引导的表示一段时间的状语连用。例如：那老人已经死了一周了。The old man has died for a week(误)他三天前就已经来这儿了。He has come here sinc
20、e three days ago(误)在以上两句中，die和come都是终止性动词，可用于现在完成时，但不能与以 since或for引导的表示一段时间的状语连用。.25 1把终止性动词改为延续性的动词。例如：The old man has been dead for a week He has been here since three days ago 2把原句中的一段时间改为表示“过去”的时间，时态由现在完成时改变成一般过去时。例如：The old man died a week ago He came here three days ago 3用“It is+时间+since”句式。例如
21、：It ishas been a week since the old man died It has beenis three days since he came here 4用“多长时间+has passed+since”句式。例如：A week has passed since the old men died Three days had passed since he came here.26examplesexamples1.他来北京五天了。He has been in Beijing for 5 days.He has come to Beijing for 5 days.()
