各位大神好,
关于曼哈顿SC 6th中的subgroup modifier,书中的例句有点不懂,请教下大家:
This model explains all known subatomic particles, SOME OF WHICH WERE only recently discovered.

This model explains all known subatomic particles, SOME OF THEM only recently discovered.

This model explains all known subatomic particles, SOME only recently discovered.

书中说这三句都是对的,但是为什么后两句不用被动语态???

因为后两句是独立主格
