请问此句中it的用法?
He is good at computer,from which it doesn't follow that his major is computer science.

it是一个形式主语,指代his major is computer science.可是把从句换成it后,好像读不通句子的意思是,他擅长计算机,但这不表示他主修计算机科学。follow在这里是"是……的必然结果”的意思。如果不用it这个形式主语,则从句为that his major is computer science doesn't follow.doesn't follow? follow后不需要加东西吗?好想没说完的样子follow在这里不是“跟随”的意思,而是“结果”的意思。比如,what follows from this?意为这事结果怎么样?我知道不是跟随,但“表示。。。的结果”不是个动词么? his major is computer science doesn't follow 就感觉这句话还没说完follow在此是一个不及物动词,后面不须加宾语。如果要加宾语,必须跟介词from,follow from.而且这句句子实际上采用了follow from 的用法,只是因为从句的原因,把from 放在了前面,from which .... follow.
