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.
