this current (going )first in one direction and then in anotherwe give it the name of an .为什么用going啊?

going是现在分词作定语,实际上是一个定语从句的省略:which is going first那怎么就知道是定语从句的省略呢?现在分词作定语时表示主动和进行的意义,而which is going first 就是一个现在进行时的句子,等你学了定语从句后就会判断了。哦,就是说这个词表示的一个句子的意思,所以也可以改写成那个句子是吧,呵呵明白了,谢谢啊,能加你q吗?以后有好多问题要问呢,看着它我头就大对的。+1348532377
