英語翻譯
我在夢中看到許多不同顏色的雲,它們身上寫著不同的數位
慢慢的每件事都變得有一點容易了
那病人對醫生感激得連話都說不出來


I see many different colors in the dream cloud,they were marked with different numbers
Slowly everything became a little easier
Grateful to the doctors that patients were even speechless

選D
D應該是behind吧
C為什麼不對呢,因為如果指的是在某物前面的化,就用in front of something,而in the front of something的意思是在什麼什麼的前部而不是前面.
