如果哪一天,你找到屬於自己的幸福時,
記得用力的抱住它......
因為那是多難得多麼美好的感覺....
也許就是你那麼一個疏忽.
它就離去了~~~~~~~~~~~~
記得用力抱住喔

推 alger0416:have a difficult time+V-ing
推 Lyon9:省略了介係詞 動詞自然就要+ing 成為動名詞了
推 Austinn:have a difficult time (in)+ Ving 這裡的in可省略
→ Austinn:have difficulty (in)+Ving 也是一樣　用difficulties也行
→ ohcaptain:補充 have a trouble/problem/good time   也是這樣
