As the boat moved off very quickly across the water.我想问,为什么是move off,如果去掉off,
变成,As the boat moved very quickly across the water.那这两句意思有什么不一样,就是加OFF和不加有什么区别,请详解

move只是“移动,搬迁,使行动,改变.位置”的意思；
move off 是强调“（从某处）离开,出发,开始移动”
在本句中,As the boat moved very quickly across the water：当这艘船迅速在水面移动”不强调方向,目的等.
而As the boat moved off very quickly across the water.“船迅速从水面驶过离开,走掉”之意.

As the boat moved off very quickly across the water.我想问,为什么是 the little boy ran very quickly across the grass这句中quick为什么加 the speedboat continued to move very quickly across the wate He ran into the room as quickly as possible.为什么用的是quickly而不是意思the water that holds up the boat is the same as the water lines across the water The water can carry a boat yet ,itcan turn the boat over as A woman fell ___ the boat ___ the water.A.off; into B.at; be A woman fell ( )the boat ( )the water.off,into,at,below,down Cars moved very slowly in the 1920s,but they ___more quickly the cat ran away as quickly as possible .为什么as quickly as it through the water 还是across the water
