在水上

They glided the boat over the water.

他使船在上滑行。

They made a raft and set it afloat.

他做了一个筏子，使它在上。

Wood floats on water.

木在上。

The boy was floating his boat.

那男孩他的小船在上着。

Since is the life in aquatic, also lets us be suitable the water cause natural subcrust current to get down.

既然是生活在上，且顺着的因缘自然地流下去。
