第二章 现在式和现在进行式
2-2 现在进行式
假如我们正在做一件事，是不能用现在式的，而必须用现在进行式，现在进行式的形态是： verb to be + present participle（现在分词） verb to be 大家都懂，什么叫做现在分词呢？现在分词就是：动词＋ing 以下是现在分词的例子
动词 现在分词
workworking
gogoing
read reading
runrunning
play playing
swimswimming
sing singing
write writing
eat eating
walk walking
comecoming
loveloving
like liking
watch watching
smokesmoking
如果我们说 i am watching a movie. 那是指我现在正在看电影，这和 i watch movies. 意义上截然不同的，i watch movies是说我有看电影的习惯。 因此有些动词是没有现在进行式的，举例来说:i am loving you. 是不通的，因为严格说起来，love是一种状态，而不是一个动作。现在进行式，都是指动作，很少指状态的。
以下是现在进行式的例子：
i am calling my father.
he is swimming now.
he is playing basketball.
they are all eating now.
he is walking in the woods now.
he is reading a detective novel.
mr. brown is driving to work.
mrs. brown is cooking.
it is raining now.
