( )on 意思:move upwards by pulling
( )up move upwards by pushing
( )up move upwards by lifting
( )up close something completely
( )up fill something completely
( )up tie something so it cannot move
不好意思,打错了,第一个词的on改成up,这样:
( )up 意思:move upwards by pulling
再加上一个:
( )on意思:place on top of something
有什么不明白吗
