Do You Realize?的歌詞如下：
Do you reali
se
the sunrise
Do you reali
se
the birds singing
Do you reali
se
the butterflies flapping their wings
Do you reali
se
the raindrops falling from the sky
Do you reali
se
the taste of a peach on a summer's day
Do you reali
se
the way that a child's laughter can light up a room?
If you don't reali
se
all these things, then what have you really got?
Have you really got nothin' at all?
Have you really got nothin' at all?
Have you really got nothin' at all? (do you realize)
Do you reali
se
the rainbow, that dances in the rain? (do you realize)
The ocean and the trees standing tall, the fireworks that burst in the night, the forest, the river and the land, do you see it all? (do you realize) do you feel it all? (reali see) have you ever wanted to cry because of all the things that you have seen? (do you realize) Have you lost your dreams, like I did, I say we should cry. And so, it seems that it is no mystery why there are some people that never give up hope, when there is no hope to give up. I will continue to cry and feel because of what I have lost and what I have seen. And so, I ask again, have you lost your dreams? Have you lost your dreams? Have you lost your dreams? (do you realize) Do you realize? (reali see) Do you realize? (reali feel) Do you realize? (reali see) Do you realize? (reali feel) Do you feel it all? (reali see) Do you feel it all? (reali feel) Do you feel it all? (reali see) Do you feel it all? (reali feel) Do you feel it at all? (reali see) Do you feel it at all? (reali feel) Do you feel it at all? (reali know) Do you know? (reali know) Do You Realize? (Do You Realize?) Do You Realize? (Do You Realize?) Do You Realize? (Do You Realize?)在以下哪個情況下，最適合使用閉包（closure）？（）（2分） A. 創建一個函式，該函式返回另一個函式，以便在需要時可以調用它。 B. 創建一個函式，該函式返回一個變數。 C. 創建一個函式，該函式需要訪問另一個函式的變數。 D. 創建一個函式，該函式需要訪問一個對象的屬性。 E. 創建一個函式，該函式返回一個對象的屬性。
正確答案是：A. 創建一個函式，該函式返回另一個函式，以便在需要時可以調用它。選項A中提到需要創建一個函式，該函式返回另一個函式以便在需要時可以調用它，這就是閉包的基本概念。當一個函式在其內部作用域中創建並保存另一個函式的引用時，就會形成閉包。其他選項中，B、C、D和E都與閉包無關。因此，答案是A。
