其实重要的区别是：
① come out of ＝ come ＋ out of.out of本身是词组（come并不是关键）,表示：
a) from with to outside of,由里向外；
b) from a given condition,在某个特定条件下；
c) from an origin,source,or cause； 起源
d) In a position or situation beyond the range,boundaries,limits,or sphere of:超过既定范围
e) In a state or position away from the expected or usual.状态脱离预期.
come就按照“来”翻译即可；
② come out from ＝ come out ＋ from,from只是介词,表方向； 而come out本身也是词组,意思：
a) To become known:变为知道
b) To be issued or brought out:带出,发布
c) To make a formal social debut 正式的出场
d) To end up; result.结果,结束
e) To declare oneself publicly:公开宣示
f) To reveal that one is a gay man,a lesbian,or a bisexual.揭示某人的性别或取向.
