1.概念与使用场景
现在进行时(be+doing)通常表示“正在发生的动作”。但当句子中的动词是表示位置
转移的趋向动词(如go,come,leave,.start,.aive,fy,dive,travel,move等)且搭配将来时
间状语时,可以表示按计划或安排即将发生的动作。
【口诀】“来、去、离开、出发”,现在进行表计划。

1.核心考点与易错点
(1①)必须有将来时间或明确将来语境
√He is leaving tomorrow.(正确,有tomorrow)
X He is leaving.(若没有语境,可能被误解为“他正在离开”,中考要求结合时间状语)
(2)be动词不可漏
X She going to Beijing next week.
(错误,缺少is)
She is going to Beijing next week.
(3)趋向动词与非趋向动词的区别
非趋向动词(如do,read,play等)用现在进行时表示“正在做”,不可表示将来,除非加
be going too
√I am reading a book now.(正在读)
X I am reading a book tonight..(错误,reading不是趋向动词,应改为I am going to read a
book tonight.)
(4)与be going to dol的区别
现在进行时表将来:按计划、安排(己确定的时间表/行程)
be going to do:打算、预测(主观意图或客观迹象)
【对比】
The train is leaving at5:00.(火车时刻表,计划)
I'm going to leave at5:00.(我打算5点走,但可能变动)
