1.The students sat in at the administrative building to protest against discrimination of race.
学生公大楼静坐,抗议种族歧视。
2.Some persons can be everywhere at home;others can sit musingly at home and be everywhere.
有些人可以四海为家地无拘无束,也有些人可以静坐家中而神游四海。
3.Don't underdo it.This doesn't mean you just sit whenever the whim strikes you.It means you set up a practice schedule and keep to it with a gentle, patient tenacity.
