entence: Being the highest mountain in the world
question: what is the function of being in this sentence
要將be a highest mountain in the world （作為世上最高的山）這idea 變成【名詞組合】，be以Ving 形態出現。
function 就是變成【名詞】組合。
只是用 the highest mountain in the world 作為subject 而唔用being the highest mountain in the world 可唔可以？
要睇情況，舉例：【作為一個男人應該承擔這責任。】
Being a man should take this responsibility.
如果沒有了Being, 就体現不出【作為一個男人】的敢於承擔。而變成講出一般男人應會這樣作而已。
