---myself,i began to eat.A Be seated B.Seated C.Seat D.Seating选什么,为什么
2、you must be firm--- you think yourself to be right.
A.on which B.where C.what D.no matter how
选哪个,为什么选这个.a和b的区别.
3.where is your father?he --- Beijing for a week.
A.has gone off to B.has left for C.has been off to D.has set off for

B.seating,现在分词表主动进行的动作.
B.where在哪一点上的意思,如果是on which ,应是you must be firm on which you think yourself to be right about.
C.has been off to 表状态

B seated 因为seat这个动作对于我来说是被动的 如果要选主动的话应该是sitting
B
C
