最近這段時間，我感到未來一片茫然。

　　In recent days, I feel uncertain about the future.

　　在布萊克教授的討論上我是一片茫然。

　　I'm all at sea about Professor Black's lectures.

　　當我想做決定時，一片茫然，不知所措！

　　When I want a decision, a loss what to do!

　　她的臉上是一片茫然的神色。

　　She has a vacant look on her face.

　　我簡直是一片茫然，我無法理解這個問題。

　　I'm all at sea. I can't understand that problem.

　　心里一片茫然想了很多多無關緊要的東西。

　　In many more oblivious to want something insignificant.

　　她打量著周圍像迷宮一般的城市市容。仍然感到一片茫然。

　　She still looked about her upon the great maze of the city without understanding.

　　經濟展一片茫然。

　　The economic outlook is hazy.
