现在完成时的被动语态精讲


grammar
Has/have been done

现在完成时(have/has + 过去分词)
?

现在完成时的动作或情况虽然发生在过去, 但它强调的是与现在的关系,用来说明现 在的情况。现在完成时不能与表示确定的 过去时间的状语连用, 如: yesterday, two weeks ago, in 1978, when I got there 等.

?

现在完成时常与 already, always, often, ever, never, yet, not...yet, just等不表示 明确的时间副词连用, 还可以和表示时间一 直延续到目前的带since, for 的状语及包括 现在在内的词连用。如: now, today, this month, this year, recently, these few days 等。

1.动作发生在过去,但再说活之前已完成,对现在 仍有影响 -Have you had lunch yet? -Yes,I have. I’ve just had it. 你吃午饭了吗? 我刚刚吃过。 ? 2.表示从过去某一时刻开始一直持续到现在的动 作或状态。这个动作或状态可能仍然在进行。 ? He has taught here since 1981 ? 他自1981年就在这儿教书。 ? I haven’t seen her for four years. ? 我有四年没见到她了。
?

一般过去时则只表示过去某时发生的动作 或情况, 与现在毫无关系。 ? Who has opened the door?谁把门开了? (现在门还开着)
?

Who opened the door? 谁开的门? (指过 去,与现在无关。现在门是关着还是开着, 没有说明。)

I have had breakfast.(现在不饿) ? I had breakfast.(只强调吃过早饭了,并不涉 及现在饿不饿)

现在完成进行时
构成:has/have been doing ? 表示从过去某时开始一直持续到现在的动 作,可能在说话时刻之前刚刚结束也可能 还将持续下去 ? 现在完成进行时和现在完成时区别: 1.现在完成进行时强调的是在一段时期内某 项活动的持续性,强调的是动作本身 2.现在完成时则是强调动作产生的结果或取 得的成就,而不是动作本身。
