The Present Continuous Tense (现在进行时态)
定义:
构成:
标志:
现在进行时态表示现在正在进行着某种事情及动作。
“be (am, is, are )+v- ing
v-ing是动词的分词形式,动词be根据主语人称进行变化。
当句中出现Look/Listen/now或有上下文提示时用现在进行时。
例如:    
Look!Han Mei is singing there!

      Listen!Jack is talking.
      What are you doing now?

It is running, now.
动词现在分词的构成规律
1) 一般情况下,在动词原形后直接加-ing. 如:work—working (工作) do—doing(做)
play—playing(玩)
2) 以不发音的字母e结尾的动词,去掉e,再加-ing. 如:
dance—dancing(跳舞) ing(来)
(但动词词尾是字母组合ee的,就不能去掉词尾e,而应直接加-ing。例如:  see-seeing)
3) 重读闭音节单词,如果末尾只有一个辅音字母,则双写这一字母,再加-ing. 如:
get—getting(得到) shop—shopping(购物)
run—running(跑) swim—swimming (游泳)
