小学语法复习精讲&专项练习:现在进行时
概念:
(1)现在进行时表示现在或现阶段正在进行或发生的动作或存在的状态。
(2)现在进行时表示动作发生的时间是“现在”,动作目前的状态是“正在进行中”。
(3)所谓“正在进行中”,是指在谈到这件事的时候,这个动作还在进行中。至于它是什么时候开始的,什么时候会停下来,不是我们关心的。所以“正在进行时”的事件,可能发生几年了,也可能只有几分钟。仍在进行中这是“正在进行时”的关键所在。它是一件持续进行的事情。
比如:
He is reading now. 他正在读书。
He is reading history books these days.这几天他正在读历史书。

现在进行时特殊用法
一.现在进行时与短暂性动词搭配使用时可表示将来的时态。如:go,come,leave,fly,move,start,begin,arrive,stay,return and so on。
Next month my family is moving to Beijing.
下个月,我家就要搬到北京去了。
My son is leaving tomorrow.
我儿子明天就走了。
二.并不是所有动词都有进行时,一些动词一般在句中不能用现在进行时态,而应用一般现在时。这些动词往往是等表示情感状态、知觉认识、愿望或短暂性的动词。如:see(明白),know(知道;了解),want(需要;想要),like(喜欢),hear,have(有),think(想;认为),hope,hate and so on。
I hate that woman.
我恨那个女人。
I hope we can go to England together.
我希望我们能一起去英国。
三.有时候也可以用介词来表示正在“进行”的动作。
He is at work.
他正在工作。
Our new high way is under construction.
我们的新高速公路正在修。
