英语中,描述行走方向的方式很多.讲解的话,需要以动词为中心.
take.
简单的含义：走几步,注意,步.
take five steps to the right(side)/the north.take five steps forward/back/straight (后面可以加to where you belong to.等)
walk.move.
除了搭配“步”外,还可以加距离“米”等.区别在于,walk强调“步行”,move泛指移动,不要求方式.
搭配toward类词或者直接加数量词：walke several steps toward the cliffside.walk foward/eastward/backward/back five steps.以上两个例句中walk与move可替换.step与meter等可替换.
go.
我没见过这个词搭配step和距离的.一般go在这类语境中只描述动作：you go along the street.go to the norh.go in this way/direction.go back to somewhere.一般如你所问地描述具体细节时,用以上几个词.
至于问题3.4变换问句现在应该不是问题了吧.
关于问题5
go/walk/move/drive north along the street,make a right turn(turn right) at the corner(at the end of it),and then walk a milion miles to the west.(You won't miss it.That I swear.)
很高兴再次见到你!
