Ⅱ. 几种常見时态的相互轉换
英语中的几种时态在一定情况下可以互相轉换，以下是几种常見的轉换形式：
一、一般过去时与现在完成时的轉换
在现在完成时中，延续性动词能与表示一段时间的状语連用，瞬间动词却不能。但是，可用別的表达方式：①瞬间动词用于“一段时间 + ago”的一般过去时的句型中；②瞬间动词可改成与之相对應的延续性动词及短语，与一段时间連用；③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中，表示“自从……以来有……时间”的意思，主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看：
A. He joined the League two years ago.
B. He has been in the League for two years.
C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
二、一般现在时与现在进行时的轉换
在一般现在时中，at加上名词表示“处于某种状态”，如at work（在工作）, at school（上学、上课）等。此短语可与进行时态轉换。请看：
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
三、现在进行时与一般将来时的轉换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语連用表示将要发生的动作。如：I am coming, Mum! 意为“我就来，妈妈！”请看：
The train is leaving soon. The train will leave soon.
四、“be going to+动词原形”与“will(shall)+动词原形”结构的轉换
“be going to+动词原形”、表示打算、计划要做的事；将来时“will(shall)+动词原形”结构在书面语中，当主语为第一人称时，常用助动词shall。在口语中，所有人称都可以用will。请看：
We are going to visit the Great Wall next Sunday.
We shall visit the Great Wall next Sunday
