现在完成时态的用法总结(完整汇总)幻灯片PPT
王伯伯在这家工厂工作十年了。
(2)非延续性动词:come,go,arrive,
reach,see,hear,close,leave,begin,start,lose,
buy,fall,join,die等,这些动词可用于完成时态,说
明某个动作的结果还存在,但不能和表示一段时间的状语连用。
例如:
【正】The play has begun
He has been a painter for two months. He has been a painter since July. He has been a painter since he moved to Japan.
(1997—2000) (came here)
(17/09/2000— 26/09/2000)
往往译成“…..过吗?”,“还有….吗?”等. 3)其肯定回答用:Yes,….have(has).
否定回答用:No,….haven‘t(hasn’t).
有时用:No,not yet.或No,never.
Let’s continue :
3.现在完成时的否定句式是 “have(has)+not+过去分词”。如: ⑥We haven‘t studied Unit 2 yet. 我们还没学习第二单元。 ⑦The train hasn‘t stopped yet. 火车还没有停下来。 注意:1)现在完成时的否定句句末往往加yet。 2)否定句常译为“还没有……”等。
2.现在完成时态既涉及过去,又联系现在,它可表示动作或状 态过去已经开始一直延续到现在,和由 “for+时间段” 或
“since+过去时间点/从句”引导的时间状语连用。例如: We have lived here for five years. 我们在这里住了五年了。 I have known him since he was a boy. 我从他还是个孩子的时候就认识他了。
