新概念英语第三册23课其中有两句比较难的句子麻烦各位帮我解答下

(1)but two classes may be roughly seen这句话书上解释为,可分为两为为什么这样解释呢???按照我们解释就是两类鸟粗略地能被看见!(2)Any shi that crosses the Pacific is accompanied for many days by the smaller albatross, Which may keep company with the vessel for an hour without visible or more than occasional movement of wing这句话是比较级句子吗??without visible or more than occasional movement of wing想了半天都不知道怎么解释???visible or more 什么意思???(3)The currents of air that the walls of the ship direct upwards, as well as in the line of its course, are enough to give the great bird with its immense wings sufficient sustenance and progress这里的as well as 是什么意思呢??还有这里的with是不是表示附和的意思,也就是说给了这巨鸟,赋予了它巨大翅膀的浮力和推力???progress查了下字典似乎没有推力的意思
