(That is just close to what you want to say, not a good sentense)
I think the origanal meaning of this statement, even in Chinese is not complete. "香港正面臨的情況" Are you talking about "社會現象"? "情況" or "問題"? Are you going to give solution to that later on? You may want to make clear about what the thesis statement is.

Hong Kong is now facing with the problem that its young people have little understanding of the ongoing events, especially in politics.
Alternatively, I think
Hong Kong is now having a situation that its young people have little understanding of the ongoing events, particularly in politics.

你的句子其實是帯點冗長、文法上的錯誤樓上dannyfish已解釋清楚。我再試試重新組句：

The situation Hong Kong's teenagers are facing is：they know little about anything、especially in politics。

Hong kong is currently experiencing a situation that, teenagers with the issue happening around them, is misunderstanding, especially related to politics.

The situation Hong Kong is facing is teenagers do not know well about events around them, especially related to politics.



acquaintance (n)的意思其實是 相識/認識 ，所以....用字不當
acquaintance(n) , 唔會用with
political (adj)，形容詞，所以related to political <-- 應該係related to politics

the situation Hong Kong facing <-- 應該係the situation Hong Kong is facing
