谁能告诉我across,cross,pass,through有什么区别啊

谁能告诉我across,cross,pass,through有什么区别啊
另外，died和dead 咋用啊

across和through 都是穿过的意思
但是across是指从表面穿过,而through是指从内部穿过
比如 Go through the forest 穿过森林
Go across the road 过马路
Go through the glass 透过玻璃.等等
cross也翻译为穿过,但是和across词性不一样,是动词,而across是介词
穿过 = go across = cross
pass 就是经过的意思,比如上学途中经过哪个人的家之类的.还有及格的意思,pass the exam...等等
died是动词die的过去式和过去分词
He died last year
dead是die的形容词形式
He is dead
