现在完成时态

(1)
目前已经完成的动作

（
4
）这个时态强调动作对现在的影响。

要点
2
：
当句子中出现表示到现在为止这段时间的状语时，
谓语动词一般用 现在
完成时
:
这类状语有：
up to now, up till now, so far, these days, this summer, for
后面
接一段时间的短语或
since
等
:

一般过去时态
要点
1
：
一般过去时 表示
(1)
过去某个特定时间发生，并且一下子就完成了的动作
（即：非持续性动作）
，也可以表示
(2)
过去习惯性的动作。
一般过去时不强调动作对 现在的影
响，只说明过去。
I had a word with Julia this morning.
今天早晨，我跟朱丽亚说了几句话。
(1)
He smoked many cigarettes a day until he gave up.
他没有戒烟的那阵子，烟抽得可凶了。
(2)
一般过去时常与表示过去的时间状语或从句连用，如：
yesterday,
last
week,
in
1993, at that time, once, during the war, before, a few days ago, when
等等。
句子中谓语动词是用一般过去时还是用现在完成时，取决于动作是否对现在有
影响。
