pass,through,across,along的区别 最好能举几个例子

pass v.+sth 通过（抽象或具体物体）e.g.pass the exam
across prep.平面穿过（立体的用through e.g.run across the street,look through the window,go through the forest）
cross v.与across向对应,可直接加名词
by pass by经过
past n.过去 in the past three years
along 沿着 walk along get along with sb.（与某人相处）
Walk through the park...

arcoss 是指横穿,through 是竖穿过某物,along 是沿着, pass 表示通过某个关口等.
