The show must be go on和The show must go on的区别少了一个be 让他们的意义 有什么不同吗?哪怕是一点点的不同~那这句话的隐身意义有什么呢 就比如 是那种比较无奈的感觉吗 好像是 离开了谁地球都是一样在旋转 没有你 生活还是要继续的那种感觉 或者是那种 非常无奈的 不得不继续下去 但是又非自己本意的那种感觉？

让我假设一下场景：
场景一：当show进行到中途，发生了点状况，可能导致中断，这时，领导指示，The show must be going on.于是下面的人员努力努力再努力，终于挺到最后。
场景二：show将在下星期一举行，但是今天收到恐吓书，说不许举行，否则xxxx。但是这个show很重要，一定要举行，于是上头指示，The show must go on.于是。。。。。。自己想象。

The show must be go on不能这么说，要说The show must be going on.
be动词后面不能加动词原形的。
The show must go on.是正确的。

区别只在于：the show must be go on 是错误的表达
而the show must go on 正确
感觉有一点你说的第二种含义,有伤痛有无奈,但一切必须得继续
像Queen的“the show must go on”里唱到的：
Empty spaces - what are we living for
Abandoned places - I guess we know the score
On and on,does anybody know what we are looking for...
Another hero,another mindless crime
Behind the curtain,in the pantomime
Hold the line,does anybody want to take it anymore
The show must go on,
The show must go on
Queen
Inside my heart is breaking
My make-up may be flaking
But my smile still stays on.
Whatever happens,I'll leave it all to chance
Another heartache,another failed romance
On and on,does anybody know what we are living for?
I guess I'm learning,I must be warmer now
I'll soon be turning,round the corner now
Outside the dawn is breaking
But inside in the dark I'm aching to be free
The show must go on
The show must go on
My make-up may be flaking
But my smile still stays on
My soul is painted like the wings of butterflies
Fairytales of yesterday will grow but never die
I can fly - my friends
The show must go on
The show must go on
I'll face it with a grin
I'm never giving in
On - with the show -
I'll top the bill,I'll overkill
I have to find the will to carry on
On with the -
On with the show -
