英语的时态问题
英语的时态可以分为:
“时”
(time)
和
“体”
(aspect)
(又称为态)
。时是指动作发生的时
间,
体是指动作发生时的状态。
时间与 体就象是坐标里的横轴和纵轴,
它们的结合交织出了
瞬息万变的时空,也构成了英语动词的时态 问题。
时间分为:过去,现在,将来,过去将来
体分为:一般(
在
某个时间
点
)
,
进行(
延续
某个时间
段
)
,
完成(
完成
某个时间
段
)
完成进行
(
延续
某个
完成
的时间
段
)
如此以来,英语中就有
16
种时态变化,现在就用动词为
write
例,看看它们的形式。
注意:
里面的斜体字部分,
由于时态过于复杂,几乎没有人真正去应用它们,
可以忽略不记。

六、过去完成时
1.
过去完成时的用法

状态可以在过去某一时间以前已经完成,

2.
过去完成时和一般过去时的比较:
过去完成时表示过去某一时刻,或某个动作前发生 的事,即过去的过去,它着眼于显示
过去发生的几个动作的先后。
一般过去时只叙述过去某时刻 或某时刻后发生的动作,
但不强
调时间顺序。
e.g.

come,
leave,
start, arrive, return, work, sleep, stay, do, play
等。
e.g.
I) We are leaving on Friday.
II) I am seeing the doctor today.
3.
有时用来代替一般现在时,表示一个经常性动作 或状态,通常是为了表示一种感情
(如赞叹、厌烦等)。
e.g.
I) He is constantly complaining about his teacher.
他老是抱怨他的老师。
II) How are you feeling today?
